why is it that a fabia Vrs (130bhp) is faster than a a3 TDi (130bhp) even though the a3 weighs less than the fabia and has the same running gear. the specs are as follows: Audi a3 1.9TDi (130ps) 3 door Weight 1200 kg 0-60 mph 10.2 s Power Output 128 bhp Torque 310 Nm Top Speed 127 mph Fabia vRS 1.9TDi (130ps) 5 door Weight 1315 kg 0-60 mph 9.2 s Power Output 130 bhp Torque 310 Nm 229 lb-ft Top Speed 128 mph as far as I am aware these both have the same engine and gearbox, do these have different mapping? even so the vRS has no more peak torque so why is it so much quicker 0-60? the only thing I can think of is tyre sizes ( a bit wider on the skoda) and aerodynamics. can any one else explain this? all figures from parkers website.
