Larrousse LH94

The Larrousse LH94 was a racing car of the French Formula 1 teams Larrousse, which was used in the 1994 Formula 1 season. He was the last model that constructed the financially troubled team and brought to the start.


The Larrousse LH94 was in the UK by the Larrousse UK Ltd.. developed, a subsidiary of the French racing team, which was led by the British engineer Robin Herd. Larrousse UK was founded in 1990 under the name Fomet as a branch of the Italian racing team Fondmetal Corse and had the Fondmetal Fomet one constructed for the 1991 season before it ran into financial difficulties and was taken over by Larrousse end of 1991.

The LH94 was an evolution of Larrousse used 1993 LH93, which in turn was based on the Larrousse LH92 1992. He differed from his predecessors in the first place through the engine: During the LH92 LH93 and was powered by a Lamborghini engine with twelve cylinders, the LH94 took advantage of a weaker eight-cylinder engine from Ford


Larrousse used 1994 Ford customer engines of the type HBF7. The engines went into its basic features back to a design from 1989. Until 1991, they were used exclusively by Benetton and enabled regardless of a power deficit compared to the ten- and twelve-cylinder engines from Ferrari, Honda and Renault individual victories. In 1993 the engine for Benetton and McLaren has been further developed. Older, less powerful versions of the HB- engine went from 1992 to various smaller teams that used it as a low-cost customer engines. 1994 drove alongside Larrousse also Arrows, Minardi and Simtek with HB engines.

The performance of HB- motor used in the version of Larrousse is reported in the literature about 705 hp. He was apart from the Ilmor engine of the Pacific teams in the weakest engine on the grid in 1994; the power deficit compared with engines from Ferrari was over 100 hp and over the ten-cylinder Renault 75 hp.

Chassis and Body

Chassis and body of the LH94 corresponded largely previous model years 1992 and 1993. Changes were limited to adjustments in the engine environment, which were made ​​necessary by the change of Lamborghini on Ford engines. Also new was the transmission. Instead of the transverse Lamborghini six- speed transmission of previous years used Larrousse now a semi-automatic six-speed gearbox, which was matched to the HB engine and has been purchased by Benetton.

The LH94 learned in the course of the 1994 season, no further development with a view to increasing the competitiveness; the tight budget of the team did not allow for such work.

However, some modifications were required mid-season, because the design requirements in the regulations in the spring of 1994 had been short-changed. These rule changes represented a response to the fatal accidents Roland Ratzenberger and Ayrton Senna is the Grand Prix of San Marino in 1994 and were intended to reduce the speed of the cars quickly and without constructive effort. Among them was the attachment of an opening in the rear of the engine cover that reduce the accumulation effect in the air scoop and thus should reduce the engine power. Other rule changes aimed at simplifying the aerodynamics in the front and rear wings; Thus, the diffuser had to be reduced in length at the rear of the vehicle. Finally, the minimum weight of the cars was increased by 10 kg to 515 kg. Larrousse put these changes to the regulations.

Racing applications

Larrousse continued throughout 1994 two vehicles of the type LH94 one. Regular driver Érik Comas and were the Monegasque debutant Olivier Beretta, in the course of the year however they were replaced by the Paydriver Philippe Alliot, Yannick Dalmas, Hideki Noda and Jean -Denis Delétraz. Only Comas scored World Cup points with the LH94. The team suffered throughout the year from a lack of technical reliability. A total of 20 failures were recorded, most of them were due to problems in the environment of the engine.


Gérard Larrousse planned to adapt the modified rules for the coming season, the LH94 and LH95 1995 as to bring them to the start. A message was received by the FIA ​​though; because of financial difficulties that ultimately resulted in the insolvency of the team, Larrousse became operational in 1995 but actually not more.
