It's been well documented that the Group B cars could reach 60 miles per hour (from standstill) in about 2.3 seconds. The modern WRC machines acheive 60mph in 3 seconds, but what about the Group A cars in between.

Does anyone know the official figures for the following cars: 1987 Group A Lancia Delta HF Turbo (8 valve), 1990 Group A Toyota Celica GT4 ST165 and the 1995 Group A Subaru Impreza 555.

It'd be interesting to know.
