yeah but its much more simple so forget torque, gear ratios, contact patch, it gives a rough guess and is good for comparisons as both cars are tested simply. Although some figures would be well out in my opinion for example the volvos wouldnt be able to put there power down(300bhp) and then would be to heavy to do such a good 1/4mile time.
The clio times are realistic enough not 100% accurate as my cup does 60 in 6.49/6.5 and im sure that you cant get it any faster than that. But the times are near enough and if you think about it theres no driver error incorporated into this test so it doesnt depends on the weight of the driver or his skill ect. So its defiantely a good way of judging!
