Development & Publicity – Mercedes Benz 300 SLR # no.1

Earlier this year Geoffrey Horton kindly forwarded some of today’s photos taken by Otto A Rentsch a tool and die maker at Adam Stamping in Union, New Jersey.

Adam Stamping was owned by Geoffrey’s uncle George Tilp who was selected by Mercedes Benz to run a highly successful team of works built and supported 300 SL’s driven by Paul O’Shea and Phil Hill from 1955 to 1957.

In 1958 Mercedes Benz shipped a 1955 World Sports Car Championship winning type 300 SLR complete with the “Blue Wonder Rennwagen Schnelltransporter” to Georges facility in New Jersey prior to the vehicles being loaned to the Ford Museum in Michigan, Otto A’s son Otto R is seen above at the wheel of the car with it’s distinctive sign writing down the side.

It turns out that the 300 SLR sent to the USA for the loan to the Ford Museum was none other than the original 300 SLR chassis no.1.

No.1 was used for extensive pre 1955 season testing and later for practice on the Mille Miglia, where of course there was no qualifying, but according to Mercedes this car was never raced.

Along the side of the car the five one – two victories scored by no.1’s siblings are recorded; the Stirling Moss / Denis Jenkinson partnership beat the solo Jaun Manuel Fangio on the Mille Miglia, Fangio then beat Moss at the Eifelrennen where Karl Kling finished fourth in a third 300 SLR behind a Ferrari 750 Monza driven by Marsten Gregory, Fangio also finished ahead of Moss in the Swedish Grand Prix.

Moss partnered by John Fitch beat Fangio and Kling at the Tourist Trophy where Kling was joined by Wolfgang von Trips and André Simon in the third placed 300 SLR, before Moss teamed up with Peter Collins to beat Fangio and Kling again on the Targa Florio where Fitch and Desmond Titterington finished fourth behind the Ferrari 857 S driven by Eugenio Castellotti and Robert Manzon.

The one omission from these results being of course the 1955 Le Mans race where the 300 SLR driven by Fangio and Moss was leading the Jaguars by two clear laps when it was withdrawn on the orders of the board of the Mercedes board of directors after parts of the sister car driven by Levegh ploughed into the spectator enclosures killing 82 spectators and injuring 100 more following an accident involving a slower car.

My thanks to Geoffrey Horton for initially forwarding Douglas Rentsch’s photographs and to Otto R Rentsch’s son Douglas for kindly giving me permission to use them, the remaining photo’s of no.1 were taken at Goodwood Festival of Speed.

Monterey Porsches – Rolex Monterey Motorsports Reunion

Leave a Reply

On our fourth visit to this years Rolex Monterey Motorsports Reunion I’ll be looking at some of the Porsches and Porsche powered cars present.

Porsche 1500 Super Continental, Rolex Monterey Motorsports Reunion,

First up the 1955 Porsche 1500 Super Continental owned and driven by Clinton deWitt, US Porsche importer Max Hoffman had the 1500 Continental supersede the 1500 America in 1955 with the less powerful ‘normal’ motors because he thought they would give his customers better low engine speed performance than the more powerful “Super” motors, the inverse of what a race car needs. The Continental name did not last long because objections from Ford who used the Continental name at that time for a stand alone brand.

Porsche 550A, Rolex Monterey Motorsports Reunion,

Porsche 550’s have a long tradition of being raced on the East and West coast of North America the 1955 34 F Modified 550 A belongs to Tom Tarbue a regular visitor to the Rolex Monterey Motorsports Reunion.

Denzel Roadster, Rolex Monterey Motorsports Reunion,

Strictly speaking the 1958 Denzel 1300 Roadster owned and driven to Terry Sullivan does not belong in this blog since Wolfgang Denzel came up with his Roadster completely independently of Porsche and like Porsche developed his own range of performance parts for use in motors sourced from contemporary Volkswagen Beetles, but I included it just for the benefit of disambiguation.

PAM Platypus Porsche, Rolex Monterey Motorsports Reunion,

Scooter Patrick, Hans Adam, and Don Mitchell are credited with building the Porsche powered 1964 PAM Platypus out of P.A.M. Foreign Cars of Hermosa Beach, California for NO FEAR pilot Miles Gupton who raced the car with a number of different Porsche motors finishing 1964 as runner-up West Coast Champion, second only to Frank Monise’s Lotus 23B. The car was latter fitted an Oldsmobile V8 but as since been restored with a 2 litre Porsche 901 motor and is currently run by owner driver Arthur Conner.

Porsche 935J, Rolex Monterey Motorsports Reunion,

From 1977 the story of the Porsche 935 became increasingly confusing with the works offering 10 ’76 935 spec customer cars known as 935/77A’s while proceeding with their own development plan on the works 935/77 that featured improved aerodynamics that necessitated a more inclined second rear screen which covered the mandated original. The works 935/77 also adopted a twin turbo motor to stay ahead of the expected competition from a turbocharged BMW CSL. Meanwhile the Kremer brothers had been developing it’s own K series of 935’s which were the class of the field at Le Mans in 1979 when a K3 took overall honours, to keep up Joest Racing, better known these days for their exploits at Le Mans with Audi, developed there own version of the 935 known as the 935J above is the 935 J 000 00012 one of two cars that appeared in 1980 for the Momo sponsored Electrodyne racing. This car, now owned by William Chip E Connor, only recorded the one race win at Daytona in July 1981 when Mauricio de Narvaez and Hurley Haywood drove the now DeNarvaez entered car to victory lane in the Paul Revere 250 at Daytona.

Porsche 962C, Rolex Monterey Motorsports Reunion,

Finally we have the 962C chassis #962-170 being offered for sale by Canepa said to be an unraced spare, one of the last four 962’s built in 1991. While I do not doubt it was never raced I wonder if as well as being sent to Team Trust in Japan sans engine it was also sent sans factory body work since to the best of my knowledge no factory supplied 962 was ever supplied with a central pillar mounted rear wing or a nose with single head lamps on either side, where as the likes of Britten Lloyd Racing, from whom Trust also bought a 962 chassis, Kremer and Joest all built a variety of body variants for the 962 with unusual headlight arrangements and centrally mounted rear wings.

My thanks to Geoffrey Horton and Karl Krause for organising and taking today’s photographs respectively.

Hot In Miami – Jaguar XJR5 #006

4 Replies

If one foreigner deserves a knighthood for trying to keep the British Motor industry alive while it was in self destruct mode twixt the early 1960’s and late 1980’s my nomination without question would go to Bob Tullis who prepared and raced a succession of British sports cars from Triumph and Jaguar to numerous victories over the 30 years in question.

Perhaps most remarkably of all having been a successful driver for 20 years, which included driving a few non British vehicles like the Dodge Dart, AMC Javelin,Bruce Jennings Porsche 911 and a one off drive in a works Oldsmobile Cutlass, Bob and Group 44 Inc business partner Brian Feurstenau managed to persuade Mike Dale of Jaguar Cars Inc, New Jersey, to fund an IMSA GT Prototype project which would see Jaguar return to Le Mans nearly 30 years after their last official appearance at the circuit in 1955.

Tullis who’s diverse endurance experience included driving the Triumph Spitfire Coupé and Howmett gas turbine car at Le Mans employed Lee Dykstra to design the new Jaguar XJR5 IMSA GTP challenger.

The XJR5 was to be powered by a variant of the 2 valve per cylinder 5.34 litre / 326 cui Jaguar V12 which Bob had successfully campaigned in his Trans Am Quaker State Group 44 Inc Jaguar E-Type and later XJS models since the mid 1970’s.

In August 1982 Bob and long time co driver Canadian Bill Adam drove the XJR5 to a debut 3rd place finish behind two of the outgoing Porsche 935’s at Road America to score a debut class victory.

Bob and Bill scored the teams first overall victory at Road Atlanta in April 1983, two more followed at Lime Rock and Mosport, Doc Bundy then shared the final XJR5 victory in 1983 at Pocono with Bob.

Today’s featured chassis #006 first appeared at the 1984 Daytona 24 Hours where Bill Adam, Pat Bedard and Brian Redman qualified 6th and were classified a disappointing 24th, the sister car driven by Doc Bundy, David Hobbs and Bob Tullius qualified and finished 3rd.

Next time out at Miami with Brian and Doc at the wheel chassis #006 qualified 4th but more importantly crossed the line first when the chequered flag fell. Despite the team increasing the capacity of it’s V12 motors to a full 6 litres / 366 cui a couple of months later this would prove be their only overall victory in 1984.

After Porsche’s top driver Derek Bell had been suitably impressed with the XJR5 after testing it in 1983 Jaguar gave the green light to Bob and Group 44 to take the cars, one of which would be #006 driven by Tony Adamowicz, John Watson and Claude Ballot-Léna to Le Mans in 1984.

Tony, John and Claude qualified 19th and retired after an accident on lap 212 while the sister car driven by Brian, Doc and Bob qualified 14th and made it to lap 291 before the gearbox gave up.

Chassis #006 returned to the States and finished the season with a 2nd place finish in the Daytona 3 Hours with Brian and Hurley Haywood at the wheel.

For 1985, by which time Lee Dykstra reckoned he had redesigned 99% of the XJR5, #006 was prepared for the Le Mans 24 hours.

Jim Adams joined Brian and Hurley in chassis #006 where the car was qualified 17th and retired after only 151 laps with a constant velocity joint failure.

The sister car driven by Bob, Chip Robinson and Claude qualified 16th and finished 13th overall and first in the GTP class.

The cars final two races were back in the States where Chip Robinson joined Hurley to score a best 2nd place finish at Pocono in September 1985 on it’s final in period race appearance.

At Daytona in December 1985 the XJR5 model appeared for the last time, before it was replaced by the all new XJR7 in 1986, Brian and Hurley sent the model into retirement with a fine second place less than 8.5 seconds behind the winning Hobert Racing Porsche 962 driven by Al’s Holbert and Unser.

Today #006 is owned by Don Miles who can be seen driving the car at Silverstone Classic events in these photographs.
