Yes, but these are not F1 cars, they are road cars. Like it or not, I am right about the TDI 130 accelerating just as quickly as the 1.8 Turbo petrol, road tests in the UK have proved it time and time again. The 1.8 Turbo petrol is not a particularly revvy engine anyway, and when people put them on the rollers, they tend to develop maximum power just below 6,000 rpm, regardless of what it might say on paper.

And the fact that in-gear acceleration isn't as good with a lower torque petrol engine is easily overcome: for maximum acceleration, one has to shift into a lower gear in order to get motor speed up into a region where the petrol engine has its maximum power band. |
I have actually come from a pretty revvy petrol powered car, and I think for real world driving, diesels are far better. Put my foot down in 5th (or 6th) for that matter, and I'll leave the vast majority of cars behind, including yours probably. I still have the option of dropping down a gear, but its a moot point, because once again, road tests have PROVED the performance of the TDI 130 (and TDI 100, TDI 150) engine. I am not trying to say that my car is the fastest around, but it is quicker than the Turbo 150 bhp engine and barely any slower than the 180 bhp Turbo engine.
You try to make out torque is useless. Well sorry, you are DEAD wrong. My car gives an incredible surge forward when the torque comes on song, which believe me, makes up for the deficit it might have by lacking the long legs of a revvy petrol engine. Not only that, but torque allows me to power out of corners quicker than the majority of petrol cars. Lets not even mention the fact the TDI will give you this performance, and probably double the fuel economy of an equivalent petrol engine.
But anyway, if you were in the UK with your car, I'd happily let you suffocate on my diesel fumes, because I know what my car can do and that is that. I speak from experience, because I have driven both petrol and diesel hot hatches, where I suspect you have not driven a diesel hot hatch. As it is, since you clearly will not have it that my car has a good engine, I am done with this thread, because quite simply I dont give a toss what you think my car wont do
