1 Million Porsche 911s: An Evolution over Seven Variants

1963: The original 911

As the successor to the Porsche 356, the 911 won the hearts of sports car enthusiasts from the outset. The prototype was first unveiled at the Frankfurt IAA Motor Show in 1963 as the 901, and was renamed the 911 for its market launch in 1964. Its air-cooled six-cylinder flat engine with two-litre displacement delivered 130 hp, giving it an impressive top speed of 210 km per hour. If you wanted to take things a little slower, you could also opt for the four-cylinder Porsche 912 from 1965. In 1966, Porsche presented the 160 hp 911 S, which was the first to feature forged alloy wheels from Fuchs. The 911 Targa, with its distinctive stainless steel roll-over bar, made its debut in late 1966 as the world’s first ever safety cabriolet. The semi-automatic Sportomatic four-speed transmission joined the line-up in 1967. And with the 911 T, and the later E and S variants, Porsche became the first German manufacturer to comply with strict US exhaust emission control regulations. The Porsche 911 became more and more powerful as displacement increased, initially to 2.2 litres (1969) and later to 2.4 (1971). The 911 Carrera RS 2.7 of 1972 with a 210 hp engine and weighing less than 1000 kg remains the epitome of a dream car to this day. Its characteristic “ducktail” was the world’s first rear spoiler on a production vehicle.

1973: G series is a success

A best-seller goes into production: Ten years after its premiere, the engineers at Porsche gave the 911 its first thorough makeover. The “G model” was produced from 1973 to 1989, longer than any other 911 generation. It featured prominent bellows bumpers, an innovation designed to meet the latest crash test standards in the United States. Occupant protection was further improved by three-point safety belts as standard equipment, as well as integrated headrests. One of the most important milestones in the 911 saga was the 1974 unveiling of the first Porsche 911 Turbo with a three-litre 260 hp engine and enormous rear spoiler. With its unique blend of luxury and performance, the Turbo became synonymous with the Porsche mystique. The next performance jump came in 1977 with the 911 Turbo 3.3 equipped with charge-air cooler. At 300 hp it was the best in its class. In 1983, the naturally aspirated 911 Carrera superseded the SC; with a 3.2 litre 231 hp engine, it became a favourite collectors’ item. From 1982, lovers of fresh air could also order the 911 as a Cabriolet. The 911 Carrera Speedster, launched in 1989, was evocative of previous legendary Porsche vehicles.

1988: 964 introduces all-wheel drive

Just when automotive experts were predicting the imminent end of an era, in 1988 Porsche came out with the 911 Carrera 4 (964). After fifteen years of production, the 911 platform was radically revised with 85 per cent new components, giving Porsche a modern and sustainable vehicle. Its air-cooled 3.6 litre flat engine delivered 250 hp. Externally, the 964 differed only slightly from its predecessors – in its aerodynamic polyurethane bumpers and automatically extending rear spoiler – but technically it was almost entirely different. The new model was designed to captivate drivers, not only with sporty performance but also with enhanced comfort. It came with ABS, Tiptronic, power steering and airbags, and rode on a completely redesigned chassis with light alloy control arms and coil springs instead of the previous torsion-bar suspension. A revolutionary member of the new 911 line right from the start was the all-wheel drive Carrera 4 model. The rear-wheel-drive Carrera 2 came on the market just six months later. In addition to the Carrera Coupé, Cabriolet and Targa versions, starting in 1990 customers could also order the 964 Turbo. Initially powered by the proven 3.3 litre flat engine, in 1992 the Turbo was upgraded to include a more powerful 360 hp 3.6 litre power unit. Today, the 911 Carrera RS, 911 Turbo S, and 911 Carrera 2 Speedster are particularly in demand among collectors.

1993: 993 – first version with a biturbo engine
911 Carrera 3,6 Coupé from 1993, Porsche AG

911 Carrera 3,6 Coupé from 1993

The 911 with the internal design number 993 remains the one true love of many a Porsche driver. The remarkably pleasing design has much to do with this. The integrated bumpers underscore the smooth elegance of its styling. The front section is lower-slung than on the earlier models, made possible by a switch from round to polyellipsoidal headlights. The 993 quickly gained a reputation for exceptional dependability and reliability. It was also agile, as the first 911 with a newly designed aluminium chassis. The Turbo version was the first to have a biturbo engine, giving it the lowest-emission standard automotive powertrain in the world in 1995. The hollow-spoke aluminium wheels, never before used on any car, were yet another innovation of the all-wheel drive Turbo version. The Porsche 911 GT2 was aimed at the sports car purist who cherished the thrill of high speeds. An electric glass roof that slid under the rear window was one of the innovations of the 911 Targa. But the real reason why dyed-in-the-wool Porsche enthusiasts still revere the 993 is that this model, produced from 1993 to 1998, was the last 911 with an air-cooled engine.
Number of vehicles produced: 67,535
1997: 996 with water cooling

The 996, which rolled off the assembly line from 1997 to 2005, represented a major turning point in the history of the 911. It retained all the character of its classic heritage, but was an entirely new car. This comprehensively redesigned generation was the first to be driven by a water-cooled flat engine. Thanks to its four-valve cylinder heads it achieved 300 hp and broke new ground in terms of reduced emissions, noise, and fuel consumption. The exterior design was a reinterpretation of the 911’s classic line, but with a lower drag coefficient (cd value) of 0.30. The lines of the 996 were also a result of component sharing with Porsche’s successful Boxster model. Its most obvious exterior feature were the headlights with integrated direction indicators – at first controversial but later copied by many other manufacturers. On the inside, drivers experienced an entirely new cockpit. Driving comfort now also played a greater role alongside the typical sporty characteristics. With the 996, Porsche launched an unprecedented product offensive with a whole series of new variations. The 911 GT3 became one of the highlights of the model range in 1999, keeping the tradition of the Carrera RS alive. The 911 GT2, the first car equipped with ceramic brakes as standard, was marketed as an extreme sports vehicle from the autumn of 2000.

2004: 997 caters to individual preferences
911 Carrera 3,6 Coupé from 2004, Porsche AG

911 Carrera 3,6 Coupé from 2004

In July 2004, Porsche unveiled the new generation 911 Carrera and 911 Carrera S models, referred to internally as the 997. The clear oval headlights with separate blinkers in the front end were a visual return to older 911 models, but the 997 offered more than just style. It was a high-performance vehicle, with a 3.6 litre flat engine that turned out 325 hp, while the new 3.8 litre engine of the Carrera S managed an incredible 355 hp. The chassis was also substantially reworked, and the Carrera S came with Porsche Active Suspension Management as standard. In 2006, Porsche introduced the 911 Turbo, the first petrol-operated series-produced car to include a turbocharger with variable turbine geometry. Model improvements in the autumn of 2008 made the 997 even more efficient thanks to direct fuel injection and a double-clutch transmission. Never before had the 911 series made such extensive allowances to suit drivers’ individual preferences, and with Carrera, Targa, Cabriolet, rear or all-wheel drive, Turbo, GTS, special models, and road versions of GT racing cars, the 911 family ultimately comprised 24 model variants.

2011: 991 sets technological standards 
911 Carrera 3,4 Coupé from 2011, Porsche AG

911 Carrera 3,4 Coupé from 2011

Internally known as the 991, this sports car embodied the greatest engineering leap in the history of the 911. For generations the benchmark in its class, this 911 generation set the bar yet another notch higher in terms both of performance and efficiency. A completely new chassis with modified wheelbase, greater track width and beefier tyres, plus an ergonomically optimised interior produced an even sportier and more comfortable driving sensation. In engineering terms this 911 was all about Porsche Intelligent Performance: even lower fuel consumption and even more power – created, for instance, by reducing the engine size to 3.4 litres on the base Carrera model (yet still delivering 5 hp more than the 997/II) and using a hybrid construction method (steel/aluminium), which led to a considerable reduction in weight. Also new: Porsche Dynamic Chassis Control and the manual 7-speed transmission. The design of the 991 likewise met with high critical acclaim. With its low, stretched silhouette, its bristling surfaces and precisely shaped details, the Porsche 911 Carrera – in the seventh generation as before – continued to be unmistakably a 911 and was thus once more setting new standards in automotive design.
In 2013, the new Targa was added to the 911 family. The latest generation of this extravagant 911 variant combined the classic Targa idea with advanced roof convenience. Just like the legendary original Targa, it featured the distinctive wide bar in place of B-pillars, a removable front roof section and a wraparound rear window without a C-pillar. But unlike the classic 911 Targa, the roof segment could open and close at the push of a button. The fully automatic roof system stowed the Targa top behind the rear seat in spectacular fashion.
The new 2015 Porsche 911 cemented its position as the best in its class in terms of performance and efficiency. The development of a turbocharged flat engine gave the world’s best-selling sports car a significant boost in power as well as considerably lower fuel consumption. The new 3.0-litre biturbo charged six-cylinder flat engine developed 370 hp (272 kW) in the 911 Carrera and 420 hp (309 kW) in the 911 Carrera S. In both cases, this represented a power boost of 20 hp over the prior model, with just under twelve per cent less fuel consumption. The 911 Carrera represented a quantum leap in innovation, featuring a sharp new look outside and Porsche Communication Management with multi-touch screen inside. Above all, however, the new 911 raised the benchmark considerably in the sports car world: more power, the enhanced Porsche Active Suspension Management (PASM) chassis and optional rear axle steering improved the best time of the 911 on the Nürburgring-Nordschleife to 7.30 minutes. Ten seconds faster than its predecessor and with an even greater lead over the competition.
Number of vehicles produced until the end of the 2016 model year: 152,659

Why are Warren and Butler (OH) County Officials Enamored with Roundabouts?

An interesting story this morning in the Dayton Daily News about interest in roundabouts on the part of Warren and Butler County officials.  Among other things, the reasoning is that if the Federal Government advocates the construction of roundabouts, then we should take notice.

I have experienced plenty of roundabouts while driving in Germany.  Yes, they can be confusing at first. But I think the real issue is how do roundabouts fare when traffic gets congested.  Are they really more effective than signaled intersections when traffic is heavy.  My sense is when there is light traffic, on county roads, roundabouts can work if drivers are accustomed to seeing them.  But Warren County is one of the fastest, if not the fastest growing county in Ohio.  In the long run, will the roundabouts be able to take additional traffic 10 years from now?  We have plenty of drunk and drugged drivers out there, and also distracted ones on cell phones. Are roundabouts easier for hampered drivers to traverse without incident?

You tell me!

Looks good when there are 4 cars entering the roundabout from the same direction!

Hacking into Keyless Entry Cars: How Easy it is!

From the British Newspaper The Sun, May 5, 2017 website!

For more on hacking and car theft see my book, Stealing Cars:Technology and Society from The Model T to Gran Torino (Johns Hopkins University Press, 2014).

A FED up Ford owner is going to extreme lengths to protect his vehicle after falling victim to a spate of keyless car thefts.
Matt Smith parked his work van behind his keyless Ford Focus, at about 9.30pm on April 14, and headed into his home –  less than five minutes later he watched as thieves drove the car away.
Matt, of Birmingham, got his car back after the robbers left it in a quiet street, but as spates of keyless car thefts are reported across the country he’s taking some extreme precautions against cyber thieves.
He said: “I put a big chain over the steering wheel and over the horn so if there’s any movement it will sound.”
On top of this site manager Matt is removing the starter relay fuse – a key component of the starting mechanism – every night.
The furious car owner was shocked at how quickly the thieves were able to break into his car and drive off, as gangs continue to target dozens of models by hacking into the keyless systems.
He said: “They got in the car without making any noise and I just saw them pull off.
“I jumped in my work van and I tried to cut them off but they got out in front of me. I took a bend too fast and hit a lamp post writing off my work van.”
Luckily for Matt, 42, who almost lost two vehicles in one night, his local Facebook community spotted his car the following morning.
There was no damage to it and he believes the thieves had planned to pick it up the following day.
Matt is one of many keyless car owners going to extreme lengths to keep their cars safe, as calls grow for manufacturers to do more.
A mum-of-seven whose keyless car was snatched from her driveway as her family slept told Sun Online she now stashes her hi-tech fob in the microwave.
Some of the cyber thieves open cars using an amplifier that extends the unlocking signal up to 300 feet to reach the owner’s fob.
Tests by the ADAC – the German AA – tricked the keyless sensor technology into thinking that the vehicle’s owner is nearby with the fob.
BMW 740, Ford Focus RS, Toyota’s Prius and VW Golf 7 GTD are among the car’s affected.

The only vehicle that the researchers failed to unlock was BMW’s i3
But they were able to start the engine.

Mercedes-Benz Entries at the 2017 Mille Miglia


Mercedes-Benz 300 SL racing sports car (W 194), Rudolf Caracciola and Peter Kurrle, starting number 613, Mille Miglia 1952.


Around two weeks to the start: On 18 May 2017, the starter in Brescia will send the cars on their way in this year’s Mille Miglia, which will take place in four stages until 21 May. Mercedes-Benz Classic will compete with ten vehicles from different eras of the historic road race, from the late 1920s to the mid-1950s. In 2017, the Stuttgart-based brand will be represented by, among others, the former Mercedes-Benz racing drivers Ellen Lohr, Roland Asch and Bernd Mayländer as brand ambassadors. A further vehicle will be piloted by Mercedes-Benz motorsport boss Toto Wolff and Aldo Costa, Engineering Director of the Mercedes AMG PETRONAS Formula One team.
“We congratulate the Mille Miglia and its organisers on this special anniversary. The race and our brand are linked by a unique success story that includes some key highlights from motorsport history, such as the overall victories of Mercedes-Benz in 1931 and 1955. Our involvement since 1930 reflects the significance of this legendary and still important road race for us,” says Christian Boucke, Head of Mercedes-Benz Classic.
Having first taken part in 2016, She’s Mercedes will again field its own team in the thousand-mile race. The initiative, with which Mercedes-Benz places an even stronger focus on the needs of female customers, will enter a total of five G-Class vehicles as part of the Mercedes-Benz Mille Miglia Challenge. She’s Mercedes will be represented in a Mercedes-Maybach G 650 Landaulet by TV presenters Cristina Chiabotto and Diletta Leotta together with Pamela Amann, development project manager of the Mercedes-Maybach G 650 Landaulet.
Magic seven
The theme of Mille Miglia 2017 is the “magic 7”: in 1927, the Mille Miglia was held for the first time; in 1947, it started up again for the first time after the end of the Second World War; in 1957, it was held for the last time as a classic road race; and in 1977, it was reborn as a historic motorsport event. Since 2012, the automobile club of Brescia has been holding the Mille Miglia with its high-calibre participants through its subsidiary 1000 Miglia Srl. Today, the only vehicles eligible to participate are those whose models competed in the original road race between 1927 and 1957.
Mercedes-Benz has been involved since 1930, so virtually since the first event. Back then factory driver Rudolf Caracciola with his co-driver Christian Werner entered in a Mercedes-Benz SSK (“ Super-Sport-Kurz”, (“Super Sport Short”)) and promptly finished in 6th place. One year later Caracciola won the Mille Miglia in 1931 as the first non-Italian driver with his co-pilot Wilhelm Sebastian in a Mercedes-Benz SSKL (“Super-Sport-Kurz-Leicht” (“ Super Sport Short Light”)). It is this triumph in the era of the supercharged racing touring cars that is being remembered in 2017 with the participation of a Mercedes-Benz SSK from Mercedes-Benz Classic.
Racing renaissance of 1952
The Mille Miglia in 1952 was the scene of the first redeveloped competition vehicle from Mercedes-Benz after the Second World War, the 300 SL racing car (W 194). In 2017 it is precisely this vehicle with the chassis number 5 that Mercedes-Benz Classic is sending to the starting line in Brescia, the very model in which Caracciola and Peter Kurrle (starting number 613) finished in 4th place. Their team colleagues Karl Kling and Hans Klenk drove the new 300 SL racing car and finished in 2nd place.
With no less than six 300 SL “Gullwing” (W 198) models Mercedes-Benz Classic is celebrating the outstanding success of the Stuttgart racing team at the Mille Miglia of 1955: back then Stirling Moss and Denis Jenkinson drove the 300 SLR racing car (W 196 S) to overall victory. And with the standard 300 SL “Gullwing” Mercedes-Benz also dominated the Gran Turismo class over 1300 cc displacement in this successful racing season.
The year 1956 is recalled with two further vehicles from Mercedes-Benz Classic in the peleton of this year’s Mille Miglia: in a Mercedes-Benz 220 a (W 180) Christian Boucke, Head of Mercedes-Benz Classic, will be at the wheel together with Bernd Mayländer, regular driver of the Safety Car in the Formula 1 World Championship. In 1956  Erwin Bauer and Erwin Grupp won in their class driving a vehicle of this model. What’s more, the racing version of the Mercedes-Benz 190 SL (W 121) is taking part in the regularity run on the trail of the road race. Last year a car of this model took part in the modern Mille Miglia for the first time. This has been made possible due to findings from 2015 relating to automotive history. They prove that in the 1956 road race a 190 SL took part (Michel Bianco and Jean Loup Pellecuer, starting number 347).
Mercedes-Benz Mille Miglia Challenge 2017
The 2017 Mille Miglia will be held from 18 to 21 May in four stages from Brescia to Rome and back. In the tracks of the legendary road race the organisers have chosen a clockwise route: on 18 May the cars start in Brescia and head west, past Lake Garda to Padua. The stage of 19 May then runs south through San Marino and Italy’s hinterland to Rome In the capital the peleton embarks on the third stage on 20 May, northwards to Parma. The fourth and last stage will reach Brescia again on 21 May.
The regularity run through the heart of Italy is one of the most exciting events globally in the automotive classic world . This is down to highlights such as the 2017 Mercedes-Benz Mille Miglia Challenge 2017 as well as the actual competition. This exclusive regularity run is taking place as a reminiscence to the major triumphs of the Mercedes-Benz brand in the competition held from 1927 to 1957.
The participants in the Mercedes-Benz Mille Miglia Challenge will drive ahead of the classic cars on the same route and will subject themselves to the same special stages. Vehicles permitted to take part are Mercedes-Benz SL sports cars of various generations, numerous vehicles from Mercedes-AMG plus models of particular historical value from product history.
For further research, Mercedes-Benz Classic M@RS is available as a comprehensive multimedia archive and search system. It is the world’s largest digital archive of an automotive manufacturer and unique in terms of its public accessibility: https://mercedes-benz-publicarchive.com/marsClassic.
Mercedes-Benz drivers at the Mille Miglia 2016
Roland AschBorn on 12 October 1950 in Altingen, Germany
Trained as a master automotive mechanic, Roland Asch began his motor racing career as a hobby but achieved victories like a true professional: after winning the German Hill-Racing Championship in 1981 and the German Motor Racing Trophy in 1983, he made his debut in the German Touring Car Championship (DTM) in 1985. He became Runner-Up in 1988 in his own Mercedes-Benz 190 E 2.3-16. In the late 1980s he won the overall rankings in the Porsche 944 Turbo Cup three times, and in 1991 took the championship title in the Porsche Carrera Cup. In the early 1990s he achieved a total of five wins and various good placings in the DTM for Mercedes-Benz. In 1993 he became DTM Runner-Up for the second time, and in 1995 moved to Ford in the Super Touring Car Cup. As a Brand Ambassador Roland Asch enjoys close links with Mercedes-Benz to this day and from time to time he can be seen at events when he takes the wheel of important racing cars from the Mercedes-Benz Classic collection.
Ellen Lohr
Born on 12 April 1965 in Mönchengladbach, Germany
Ellen Lohr came to motorsport via karting, in which she was active from 1979 to 1983. Her greatest triumphs were taking part in the Junior Karting World Championship as well as 1st place in the Northwest German Regional Karting Championship. After competing in the German Formula Ford 1600 series (German Champion in 1987) and first races in the DTM (BMW) and German Formula 3 Championship with VW in 1989/90, she was signed up by the AMG-Mercedes team for the German Touring Car Championship. Ellen Lohr is the first and only woman to date to have achieved a DTM victory, which she won in May 1992 at the motor racing festival in Hockenheim at the wheel of an AMG-Mercedes 190 E 2.5-16 Evolution II. For the 1995 season, she moved to the Mercedes-Zakspeed team, and in 1996 drove for the AMG-Mercedes Persson MS team. In 1997, she competed in the European Truck Racing Championship at the wheel of a Mercedes-Benz racing truck. Subsequently, Ellen Lohr has continued to be actively involved in numerous other racing series, including the Paris–Dakar Rally since 2005 and again in truck racing since 2012.
Bernd MayländerBorn on 29 May 1971 in Waiblingen, Germany
Bernd Mayländer makes regular appearances in Formula One at the front of the field. That‘s because the racing driver, born in Waiblingen in 1971, has since 2000 been the official driver of the Mercedes-Benz Formula One safety car – currently a Mercedes-AMG GT S (C 190). Mayländer began racing in 1990, first taking part in Porsche Club Sport, Porsche Carrera Cup (overall victory in 1994) and Porsche Super Cup as well as in long-distance races. Driving for the Persson Motorsport team, from 1995 he participated initially in the German Touring Car Championship (DTM) and the International Touring Car Championship (ITC), while, from 1997, he drove an AMG-Mercedes CLK-GTR in the FIA GT Championship, in which, together with Klaus Ludwig and Bernd Schneider, he won the 1997 race in Spielberg in an AMG-Mercedes CLK-GTR. In 2000, he was victorious in the 24 Hours Nürburgring at the wheel of a Porsche 996 GT3. Bernd Mayländer contested his final DTM season in 2004 as a member of the Rosberg team driving a Mercedes-Benz C‑Class.
Mille Miglia 2017: Mercedes-Benz Classic vehicles
Mercedes-Benz SSK (W 06, 1928)
The Mercedes-Benz, SSK (W 06) was the most exclusive and fascinating model of the S-series, a range of high-performance sports cars equipped with supercharged six-cylinder engines and introduced in 1927. The model designation of the 7.1-litre sports car stood for Super-Sport-Kurz (Super Sport Short) and featured a shorter wheelbase alongside its particular sportiness. After the S-type as the first model of the series had scored numerous victories, its successor models SS and SSK continued the success story. In the summer of 1928, works driver Rudolf Caracciola won the Gabelbach Race at the first attempt as well as the races at Schauinsland and Mont Ventoux with the brand-new SSK. In 1930 the SSK took him to victory in the European Hill-Climb Championship. In the same year the supercharged sports car was entered in the Mille Miglia for the first time: Rudolf Caracciola and Christian Werner took sixth place in the overall rankings with a time of 17 hours and 20 minutes. The weight-reduced 1931 version with an increased output of 220 kW (300 hp), also known as the SSKL (Super-Sport-Kurz-Leicht - Super Sport Short Light), achieved a spectacular success in the Mille Miglia: In April 1931, Rudolf Caracciola was the first non-Italian to win this demanding road race from Brescia to Rome and back – setting a new course record of 16 hours and 10 minutes.
Technical data of the Mercedes-Benz SSK (standard-production version)Production period: 1928-1932
Cylinders: 6/in-line
Displacement: 7065 cc
Output: 125 kW (170 hp), with supercharger 165 kW (225 hp)
Top speed: 192 km/h
Mercedes-Benz 300 SL racing sports car (W 194, 1952)
When Mercedes-Benz planned to return to motor racing following World War II, sports racing cars were initially the only consideration. This was due to the fact that new Formula One regulations were announced for 1954, and the limited resources prevented previous development of a Grand Prix car based on the old formula. The new 300 SL racing sports car (W 194) used many existing components such as axles, gearbox and engine from the prestigious Mercedes-Benz 300 (W 186) saloon. A brand-new innovation was the extremely light yet rigid space frame, enveloped by a streamlined body made of light-alloy sheet metal. Because the space frame was built relatively high on the sides, the racing sports car was fitted with the characteristic gullwing doors. The car was powered by a 129 kW (175 hp) M 194 in-line six-cylinder engine with a displacement of three litres. In its very first race, the 1952 Mille Miglia, the 300 SL achieved a second place with Karl Kling and Hans Klenk. After this, one victory followed another: The 300 SL scored a one-two-three victory at the Grand Prix of Bern (Switzerland), followed by spectacular one-two victories at the 24 Hours of Le Mans (France) and at the Carrera Panamericana in Mexico. In the “ Nürburgring Jubilee Grand Prix” the 300 SL, which was entered in a roadster version in this race, even achieved the top four places.
Technical data for the Mercedes-Benz 300 SL racing sports car (W 194) In use: 1952 Cylinders: 6/in-line Displacement: 2996 cc Output: 129 kW (175 hp) Top speed: 230 km/h
Mercedes-Benz 300 SL “Gullwing” (W 198), 1954-1957)
In February 1954, the 300 SL standard-production sports car (W 198) celebrated its world premiere at the International Motor Sport Show in New York. The coupé was referred to as the “Gullwing” owing to the distinctive roof-mounted doors resembling a gull’s wings. The high-performance sports car was based on the legendary 300 SL racing car (W 194) from the 1952 season. It was the first standard-production car with a four-stroke petrol injection engine. With an output of 158 kW (215 hp) – a good 20 percent more than the carburettor-fed racing version of 1952 – and a maximum speed of up to 250 km/h, the W 198 was in the top echelon of standard-production sports cars in its day, which also made it predestined for racing. One legendary triumph was the triple class victory of the 300 SL standard-production sports car in the 1955 Mille Miglia. John Cooper Fitch and his co-pilot Kurt Gessl achieved fifth place in the overall ranking in his car bearing starting number 417 (which stood for their starting time of 4:17 a.m.), heading the class for standard-production sports cars above 1.3 litres and followed by two more “Gullwing” cars. Between 1954 and 1957, a total of 1400 units of the 300 SL “Gullwing” were produced, no fewer than 867 of them in the year of its Mille Miglia class victory in 1955.

Mercedes-Benz 190 SL (W 121, 1955-1963)
Along with the high-performance sports car 300 SL, in February 1954 Mercedes-Benz unveiled the prototype of the elegant, compact roadster model 190 SL (W 121). The open-top two-door model was conceived as a sportily-elegant two-seater touring vehicle and was, especially in its revised production version, closely based at a stylistic level on the 300 SL “ Gullwing” sports car (W 198. Designed as a roadster right from the beginning the 190 SL established the tradition of open-top SL sports cars. At a technical level, it was more closely related to the Mercedes-Benz 180 “Ponton” saloon (W 120), using the latter’s shortened floor assembly. The 1.9-litre petrol engine rated at 77 kW (105 hp) was newly developed. The four-cylinder power unit featured an overhead camshaft and was to found an entire family of engines. The 1956 Mille Miglia was contested by the French team of Michel Bianco/Jean Loup Pellecuer in a 190 SL (starting number 347). This is confirmed by documents in the archives of Mercedes-Benz Classic and in the Museo Mille Miglia in Brescia. This fact, rediscovered in 2015, made the 190 SL Roadster, which is popular among collectors, eligible for the Mille Miglia from 2016. A total of 25,881 units of this model were built from 1955 to 1963, some 10,000 of them going to the USA.

Mercedes-Benz 220 (W 180, 1954-1956)
Unveiled in spring 1954, the 220, also called the 220 a (W 180) internally to differentiate it from its predecessor model bearing the same name, was the first Mercedes-Benz six-cylinder model with a self-supporting design. Its modern, spacious “Ponton” body, which Mercedes-Benz had unveiled six months earlier in the mid-size model, offered previously unknown spaciousness and comfort. A single-joint swing axle, which had been introduced into standard production with the 220, ensured safe handling. Several Mercedes-Benz 220s participated in the 1956 Mille Miglia in the class of standard-production special touring cars. In this class, the vehicle chassis and engine could be modified. The Erwin Bauer/Erwin Grupp team won its class in the legendary Italian road race in a special 220: in the racing division headed by Karl Kling, three vehicles were prepared specifically for the Mille Miglia. They were already equipped with the twin-carburettor system of the 220 S successor model, with which the engine developed approximately 85 kW (115 hp). Shorter and harder springs as well as modified shock absorbers were fitted for sporty driving. In addition, the driver could change gears via a floor shift, as in the 190 SL – instead of the otherwise fitted column shift.
