The famous drag race car was a 4.2. Autocar believed the car had a special engine in it as it was so fast, so much so that they took it to a rolling road. The figures were exactly as quoted by the factory for a 4.2. The Top Gear road test car had a Tuscan Challenge 4.5 fitted.

Thats good to hear....beating some of the best at the time on a standard engine we can all have

Yup 4.2 and that drag race wasthe inspiration for fighting torque.

With those pipes in the engine,looks like a 4.5 to me, so why did they state it was a 4.2
