The Shadow DN5 was a Formula One car used by the Shadow team during the 1975 Formula One season . Updated to a 'B' specification, it was used through the 1976 Formula One season and for the first two races of the following season. It was qualified on pole position three times, and twice achieved a fastest lap in a race. Its best finish in a race was third (twice), both times driven by Tom Pryce .
33-478: The Shadow DN5 was designed by Tony Southgate . A development of the previous year's DN3 , the DN5 was more aerodynamically refined and had its weight distribution rearranged. It was updated into a 'B' specification for the following season, prior to which Universal Oil Products , the team's major sponsor, withdrew its financial support. The DN5 proved to be a fast car, which qualified well several times. In fact, for

264-880: The Audi R8C , which was a major influence in the Bentley Speed 8 , which won Le Mans in 2003. He continues to be a regular visitor to current and historic race meetings. Southgate is the only chief engineer to have won the Triple Crown of Motorsport with his cars: Indianapolis 500 with Eagle TG2 in 1968, the Monaco Grand Prix with the BRM P160B and the 24 Hours of Le Mans in 1988 and 1990 with Jaguar XJR-9 and Jaguar XJR-12 . Tony Southgate became interested in motorsport during his engineering apprenticeship and, like many aspiring racing designers in
297-661: The BRM P153 , appeared in time for the first race of the 1970 season in South Africa . BRM enjoyed a renaissance with the P153 and its successor the BRM P160 . The P160, in particular, was highly competitive during the 1971 season; drivers Pedro Rodríguez and Jo Siffert often ran near the front of the field, only for poor reliability to let them down before the finish. Continued development work reaped vast improvements. In

The EXP Speed 8 debuted in the 24 Hours of Le Mans in 2001 and won the race in 2003 . It has a strong resemblance to and shares some technology with the Audi R8C , which had raced only once before Audi dropped the project to focus on the later dominant Audi R8 . The EXP Speed 8 marked Bentley 's return to racing after
363-639: The Ford RS200 . In 1983 Southgate designed his last Formula 1 car, the Osella FA1E. The design was severely constrained as Osella Squadra Corse did not have sufficient finances to build an entirely new chassis, forcing Southgate to adapt some parts (gearbox and rear suspension) of the Alfa Romeo 182 of previous year to fit an engine from Alfa Romeo . After the experience on Can-Am cars with Shadow, Southgate collaborated with Ford in 1982–83. with

After Lotus, Southgate returned to Shadow, but left the team again at the end of 1977 together with Franco Ambrosio , Alan Rees , Jackie Oliver and Dave Wass to form Arrows . Arrows' first car, the FA1 , was almost identical to the Shadow DN9 , which Southgate had designed while at Shadow. The FA1 was comfortably leading its second race,
429-539: The South African Grand Prix , at the hands of Riccardo Patrese , when its engine blew, forcing it to retire. The Shadow team successfully sued Arrows for infringement of its copyrights and the Arrows FA1 was declared illegal in a UK court judgement on 31 July. Southgate had anticipated this and had completed an alternative design dubbed Arrows A1 which was swiftly produced without Arrows missing
462-837: The World Sportscar Championship three times and the Le Mans 24 hour race twice. The XJR-9 also raced in North America in the IMSA GT Championship . It won on its debut at the 24 Hours of Daytona in 1988, and in the final race of the season at Del Mar. He remained at TWR until 1990. Southgate subsequently worked on sports cars for Toyota ( Toyota TS010 1991–93), Ferrari ( Ferrari 333 SP 1993–95), Lister , Nissan ( Nissan R390 GT1 1996–97) and Audi ( Audi R8R and R8C ).

495-508: The 1972 season BRM and Tony Southgate parted company. BRM finished the season in seventh place. At the end of 1972 Shadow Racing Cars founder Don Nichols approached Southgate to design a Formula One car for his team to enter in the 1973 World Championship. Shadow had already been involved in the CanAm sportscar series for nearly two years, and with UOP sponsorship Nichols was planning an entrance into Formula One. Southgate designed and built
528-695: The CanAm championship. In the same year Peter Revson died while testing the Shadow DN3 at Kyalami . Tony Southgate designed the Shadow DN5 for the 1975 Formula One season. The car proved very fast, with Jean-Pierre Jarier and Tom Pryce both winning pole positions during the year, however it had poor reliability, often retiring when in a points scoring position. At the end of 1975 the withdrawal of Shadow's main sponsor UOP prompted Southgate to move to Lotus , where he worked alongside Peter Wright on
561-493: The car (and some driver induced errors) meant that Jarier finished only two races during the season. The best of these was fourth at the Spanish Grand Prix , for which he was awarded half points due to the race being stopped as a result of a bad crash. He also switched to a Matra V12 powered DN7 for two races towards the end of the season. An updated version of the previous year's DN3 was driven by Tom Pryce for
594-558: The car for 2003, leading to the change of name to simply Speed 8. The flat front end was replaced with a raised crash box for a nose, while deep valleys ran between the nose and fenders. This required the addition of large horizontal bodywork between the nose and fenders to shroud the suspension arms of the Speed 8. The cockpit would also be tapered to allow for better airflow to the rear wing. Bentley also decided to switch to Michelin tyres for their 2003 campaign. In 2001 Bentley returned to
627-407: The driver to abandon the car. Bentley returned in 2002, using their new larger engine, now running a lone entry as a testbed for the evolved Speed 8 in 2003. The car managed fourth place, once again behind only R8s. For 2003 , Bentley decided that their new evolved Speed 8 would need competitive testing in order to prepare for an overall win at Le Mans. The pair of new cars were therefore entered in
660-458: The end of the season, the achievement was marred by Siffert's death in a non-Championship race at Brands Hatch . Unfortunately for BRM and Tony Southgate his 1972 design, the BRM P180 , was not as competitive as the previous model. Siffert's replacement Jean-Pierre Beltoise managed to win a rain-hit Monaco Grand Prix in the older P160, and with it take BRM's final Formula One victory. During

However, production was soon shifted to the US, to where Southgate once again relocated. Drivers George Follmer and Jackie Oliver were immediately competitive in the DN1. In 1974 the Southgate-designed Shadow DN4 earned first and second in
759-416: The first race of the season, the Argentine Grand Prix , Jarier, the team leader qualified the DN5 on pole. However, on race day, the car failed to complete the warmup lap due to a crown wheel and pinion failure in the gearbox. Jarier took pole again for the following Brazilian Grand Prix , but retired on lap 32, having led for most of the race (and achieving fastest lap). Ultimately, the poor reliability of

Pryce fared better than Jarier with the DN5 and managed several finishes; he finished sixth three times, finished fourth in Germany and third in Austria . He had qualified on pole for the British Grand Prix , but like Jarier in Brazil, retired from the lead in the race itself. The DN5 was updated into a 'B' specification for the 1976 Formula One season . However, while

In 1962 Broadley gave Southgate his first job, as a draughtsman for Lola Cars . Southgate gained a broad grounding in many areas of motorsport design while at Lola. He was involved in projects as wide-ranging as
891-545: The latter half of the season Siffert and Peter Gethin (who had replaced Rodríguez following the latter's death) won back-to-back victories in the Austrian and Italian Grands Prix. Gethin's victory at Monza was taken at an average speed of over 150 mph (240 km/h) and stood as the fastest ever Grand Prix win for over 30 years. Although the BRM team finished second in the Constructors' Championship standings

He also assisted with designs for IndyCar chassis, one of which evolved into the Honda RA300 Hondola Formula One race-winner. It was his experience with single-seater and IndyCar designs which prompted Dan Gurney to hire Southgate for his All American Racers team, based in California , to design some of
957-406: The reliability of the DN5B was much improved from its parent, it was not as competitive, at least during the latter part of the year. Jarier qualified his DN5B third on the grid in the Brazilian Grand Prix and ran second for much of the race before crashing. This left Pryce to take third place, the best result for the team during the year. While both drivers regularly finished in the top ten, there

Bentley also chose to run on Dunlop tyres instead of the Michelins used by Audi. Following its initial year of competition, the Audi-sourced V8 was modified to better suit the EXP Speed 8. This saw the engine expanded to 4.0 litres, producing approximately 600 hp . This would ultimately lead to Bentley redesigning
