You can say what you want about beating car off the mark.
As every one should no it all comes down to the driver. To answer your question put the same driver in all differant cars & run them 0-100 then you can work out whos faster or not.
Also your 1200 weighs 700kg the average commodore weighs 1400kg so to match a V6 commo you need half the power & half the weight. If you get an a15 to make 140 HP in a 1200 you will be very suprised what it will do on the street if you can drive it properly.

P.S I am a bit pissed
