The Leyton House CG911 was a Formula 1 racing car from the British racing team Leyton House , which was used in the 1991 Formula 1 season . The Leyton House was the only one in the field to be powered by the debut engine Ilmor V10 . At the beginning of the season, Ivan Capelli and Maurício Gugelmin drove the car. Karl Wendlinger replaced Capelli in the last two races in Japan and Australia. In 32 starts, the drivers reached the finish line only twelve times and scored one world championship point. Leyton House finished the season in twelfth place in the constructors' championship. The following year the car was modified and used again as the Leyton House CG911B . The CG in the type designation was a tribute to team manager Cesare Gariboldi, who died in a car accident in 1989 .

construction

The previous model in the 1990 Formula 1 season was the Leyton House CG901 . The main innovation of the CG911 was the Ilmor engine with ten cylinders. The engine manufacturer made its Formula 1 debut in 1991 and developed an output of around 490 kW (≈670 hp) from a displacement of 3.5 liters, whereas the Judd V8 from the previous year only developed around 470 kW (≈640 hp).

1st run - GP USA

In qualifying for the US Grand Prix in Phoenix , Capelli was only able to qualify for 18th place on the grid (1: 26.121 min). Gugelmin came in 23rd with a time of 1: 26.865 min. Both Capelli and Gugelmin were satisfied with the performance of the Ilmor engine because, according to the two racing drivers, it “takes a bite and has a good grip on the gas”. However, the race ended for Leyton House in a double retirement. The reason for Gugelmin's departure on lap 35 was a gearbox damage caused by a broken second gear. In addition, its engine overheated after a hole was made in the radiator. Capelli made it into the pits on lap 41, when his transmission also went on strike due to the transmission oil pump breaking.

2nd run - Brazilian GP

Gugelmin qualified with the defeated Leyton House in his home race in the fourth row of the grid in 7th place (1: 18.664 min) and thus promising for possible world championship points. Capelli put his car in 16th place with a time of 1: 19.517 minutes. During the warm-up for the Grand Prix, the fire extinguisher of Gugelmin's car activated itself due to a technical defect and caused first and second degree burns on the driver's legs. Gugelmin started, but gave up the race on the ninth lap due to his pain. On the 18th lap the power transmission broke down on Capelli's car, causing him to retire and Leyton House suffered another double failure. The journalist Heinz Prüller named engine failure as the reason for failure.

3rd run - GP San Marino

Leyton House fired Simon Keeble, one of his two team managers , in the run-up to the San Marino GP in Imola . In qualifying, Gugelmin placed his Leyton House in 15th place with 1: 25.841 minutes. His team-mate was 23rd, almost a second behind (1: 26.602 min). The race was once again disappointing for Leyton House. Capelli was catapulted out of the race on the 24th lap by a flat tire with a subsequent spin. Gugelmin made it to lap 56 before engine failure (piston) stopped him. In their publication, Malberg / Braillon cite a failure in the power transmission as the reason for failure. Gugelmin was rated 12th due to the distance covered.

4th run - Monaco GP

The Monaco Grand Prix took place in the urban canyons of Monte-Carlo from May 10th to 12th, 1991 . Gugelmin reached 15th place in the second qualification training on Saturday with 1: 23.394 min. With a lap time of 1: 23.642 min, also driven out on Saturday, Capelli was only registered in 22nd place. The race on Sunday took place at an optimal outside temperature of 21 ° C. However, Capelli dropped out early because his Leyton House had a brake fluid leak on lap eight and the braking effect failed. Gugelmin finished the race on lap 44 when the gas cable on his car snapped. It was the fourth consecutive double loss for Leyton House.

5th run - Canadian GP

The Canadian Grand Prix at Circuit Gilles-Villeneuve took place from May 31 to June 1, 1991. In the qualification on Friday the track was partly wet, so that most of the drivers only achieved their best times in the qualification on Saturday; so did Capelli, who put his Leyton House in 13th place with 1: 22.443 min. Gugelmin had a dark qualifying Saturday. With 1: 23.650 min, which is more than a second slower than his team-mate, it was only enough for him to place 23 on the grid. The race on Sunday took place at 28 ° C outside temperature and gave Leyton House another double retirement. Capelli's car had an engine failure due to overheating on lap 43. Gugelmin also retired on lap 62 with engine failure.

6th run - GP Mexico

The sixth Formula 1 round in 1991 was the Mexican Grand Prix at the Autódromo Hermanos Rodríguez . Qualification training was disappointing for the Leyton House pilots. Gugelmin took 21st place with 1: 20,200 min. Capelli came in 22nd place and thus also in row 11 with an almost identical time of 1: 20.252 minutes, both drivers set their fastest times in qualifying practice on Saturday. The race on Sunday turned out to be another fiasco for the team ; a phenomenon Leyton House suffered from since the beginning of the season. Engine failure stopped both Gugelmin (16th round oil pressure) as well Cappelli few laps later, on lap 20, Cappeli over turned while his engine to 19,000 min -1 and gave Leyton House another double failure.

7th run - French GP

Overview of the failure reasons from which Leyton House suffered in 1991.

The seventh round of the 1991 Formula 1 season took place on the newly opened track in Magny-Cours from July 5 to 7, 1991. After Leyton House had followed the peloton in the previous races, Gugelmin qualified surprisingly well in 9th place with a time of 1: 24.044 min and was behind Nelson Piquet on the Benetton B191 (1: 23.626 min). Capelli took 15th place with 1: 24.587 min. On race Sunday, Gugelmin missed a world championship point for sixth place with 7th place. However, he managed to get a Leyton House to the finish line for the first time this season, Capelli had already retired in the 8th round. The lathe and subsequent engine stall occurred when Capelli tried to avoid the Morbidelli, who was also turning in front of him.

8th round - GP England

The British Grand Prix took place at the Silverstone Circuit . It was the eighth World Championship round of the 1991 Formula 1 season and thus also half-time for the Leyton House team. In the previous seven races, Leyton House had only reached one finish, that of Gugelmin in Magny-Cours. Gugelmin qualified for 9th place with 1: 24.044 min. He was able to run out of time on Saturday. Capelli was half a second behind (1: 24.587 min) in 16th place. However, Leyton House's race ended again with a double retirement. Capelli fell out on lap 16 due to a spin. Prüller puts this spin as lap 9. Gugelmin gave up on lap 24 after strong vibrations had become noticeable on his car. However, Prüller cites leg cramps as the reason for failure at Gugelmin.

9th run - GP Germany

The German Grand Prix took place at the Hockenheimring on July 28, 1991 . Both Leyton House drivers qualified with 12th place (Capelli 1: 41.330 min) and 14th (Gugelmin 1: 41.715 min) in midfield. But once again, technical unreliability led to a double failure. On lap 22, Gugelmin's car suffered a final gearbox damage after having been driven without a clutch since the start of the race. One lap before that, Capelli made his pit stop. Capelli came up to the 36th round. It was stopped by electronic damage (misfire), which led to engine failure. At least Capelli was spared the long walk back to his box. After the race he was taken along by Gerhard Berger ( McLaren ) as a "co-driver".

10th run - Hungarian GP

On the Hungaroring , sometimes referred to as the "Mickey Mouse Course" , Leyton House was able to largely compensate for the performance deficit of the Ilmor engine compared to the competition. Capelli finished ninth in the qualification with a time of 1: 19.794 min. Gugelmin came in 13th with 1: 20.024 min. The race with outside temperatures of 35 ° C developed into a heated battle. In the first corner the order of Senna , Patrese , Mansell , Prost , Berger , Alesi and Capelli was in seventh place. However, Gugelmin had to pit on lap eight after suffering a tire damage on the left rear in a collision with Modena and Pirro. On lap 47, Capelli picked up a fresh set of tires. For the first time both Leyton Houses reached the goal. Cappeli took a world championship point with his 6th place, but only because Prost retired from the race on lap 28 with engine failure. It was the first and only championship point for Leyton House in 1991. Gugelmin completed Leyton House's performance with 11th place.

11th run - Belgian GP

The Belgian Grand Prix took place at the Circuit de Spa-Francorchamps from 23 to 25 August 1991 . Capelli qualified with his car in 12th place with a time of 1: 52.113 min. Gugelmin completed the result with 1: 52.623 min, which brought him 15th place. But the same fate befell both drivers on race Sunday. Gugelmin was already out on the 2nd lap due to engine failure (engine burst). The same thing had happened to him during the warm-up. Capelli followed on lap 14 with the same defect. Overall, it was the ninth double failure of the season.

12th round - Italian GP

The Italian Grand Prix in Monza from September 6th to 8th, 1991 was the 12th Formula 1 round of the 1991 season. Capelli finished 12th in qualifying practice (1: 23.674 min). Gugelmin was eighteenth with 1: 24.391 min. This race did not end in catastrophic failure for Leyton House; both cars reached their destination. However, Gugelmin came to the pits on lap 7 to have the ignition box changed after a misfire on the Ilmor. His pit stop lasted 3:45 minutes. Capelli changed his tires on lap 12. Gugelmin crossed the finish line in eighth place, Gugelmin came in 15th.

13th run - GP Portugal

In the run-up to the Portuguese Grand Prix on the Circuito do Estoril , the previous team boss Takagi was no longer to be found. He was embroiled in a financial scandal and arrested. Mercedes caught the financially struggling team from Leyton House and "leased" it as a test department for the group. Under pressure from Mercedes, Mercedes junior Karl Wendlinger should contest the last races of the season. Regardless of these events, or precisely because of them, both Leyton House pilots showed a clean qualifying result. Capelli came in 9th place (1: 15.481 min). Gugelmin even came in 7th place (1: 15.266 min). Gugelmin kept this place in the race and again just missed important championship points. Capelli had to park his car on lap 65 due to a broken nose after a collision.

14th round - GP Spain

In qualifying at the Circuit de Catalunya , Capelli placed his Leyton House in 8th place with 1: 20.584 min. Gugelmin followed in 12th place with a time of 1: 20.743 minutes. In the race, Capelli still fell in the first round due to an accident with the BMS Scuderia Italia by Emanuele Pirro made. Gugelmin finished seventh and narrowly missed the points again.

15th round - Japanese GP

For the last two races of the 1991 Formula 1 season, Ivan Capelli was replaced by the young Austrian Karl Wendlinger , who brought enough sponsorship money to finance Leyton House's start in the last two races of the season. Capelli drove in the 1992 Formula 1 season at Ferrari as a replacement for the dismissed Alain Prost . In qualifying training on the Suzuka International Racing Course , Gugelmin came in 18th. Wendlinger came in 22nd in his Formula 1 debut. The race ended for Wendlinger on the first lap when he was involved in a mass accident. Gugelmin finished in 8th place with his Leyton House.

16th run - Australian GP

The season finale of the Formula 1 season took place on the Adelaide Street Circuit . Qualification training turned out to be difficult for Wendlinger, due to his size he had shifting and seating problems. Wendlinger described the situation as follows:

"I lose three tenths in every corner because I still have to stir the gearbox, although I should have been on the accelerator long ago."

In the morning training, Wendlinger slipped into the wall, destroying the front wing and wishbones. Initially qualified in 19th place, Wendlinger fell back to 26th and last place on the grid with a time of 1: 18.282 minutes because Martin Brundle (Brabham-Yamaha) blocked him on a fast lap. Gugelmin was a whole second faster and reached 14th place with a time of 1: 17.344 min. The race, known as the "Rain Battle of Adelaide", was stopped after 15 laps had been driven. Wendlinger overtook nine opponents within a few laps and was soon in 15th place. On lap seven, however, he had to pit to have the ignition box replaced. He then drove to 20th place. Gugelmin squeezed past Stefano Modena on lap 14 on the finish line , but lost control of his car due to aquaplaning and collided with the pit wall. Two marshals were injured. However, since the race was stopped on the 15th lap, Gugelmin was classified in 14th place.
