 In the meantime, the team's promised Ford TEC engines also not ready (the deal to build the turbocharged V6 Ford was only agreed to at the 1984 British Grand Prix and engine designer Keith Duckworth lost 4 months trying to unsuccessfully develop a 4 cylinder engine before eventually deciding on a V6).This forced Haas to do a deal with Hart Racing Engines to use their 1.5-litre turbocharged, 4 cylinder 415T engines until the Ford units could be completed, while Goodyear became the team's tyre supplier.When the team made their first race appearance at Monza, Jones qualified 25th out of 27 cars, before the Hart engine failed after only six laps.
