Despite a limited budget, Larrousse had a testing schedule planned for the 1994 season. However, following the deaths of Ayrton Senna and Roland Ratzenberger at the San Marino Grand Prix, the technical regulations were changed for subsequent races to slow the cars down by making the chassis produce less downforce and the engines less power. This resulted in new components having to be built for the LH94 and a new supply of spare parts to be confirmed for the rest of the season, which eliminated the financial support for any further development.
