Quote from Autocar Roadtest of the 156 Veloce 20V JTD 14 October 2003:
"Our test was blighted by incessant rain, hardly ideal conditions for a front-wheel-drive car with enormous torque, but despite this the 156 ripped to 60mph in 7.6 seconds. This is a mighty engine, one which puts its rivals in the shade: neither the 163bhp Audi A4 2.5TDi (8.9sec) or the BMW 320d (9.3sec) can live with that pace and their lower torque outputs mean itís a similar story for in-gear acceleration. Here the JTD really hits its stride, storming from 40-80mph in fourth in just 8.7 seconds. Not only is that substantially quicker than the diesel competition, it also beats our favourite petrol-engined junior exec Ė the BMW 330i Ė over the same test by 3.5sec."
this is like pulling teeth.
first of all comparing it to a 163hp audi and a 150hp BMW which both probably weigh more, what do you expect?
ill do my best to explain it for you all one last time,
being at around 2000rpm in a diesel is around the same as being at 4000rpm in a petrol.
you are using all the diesels available power, because you are at a lower revs for a given gear ratio you think that are not 'ragging' it. of course you are you are 2000rpm or so from peak power and operating range.
IIRC 4th gear in the 330ci will do around 125mph so put the alfa in a gear that can do around that speed then put your foot down. or try it in 3rd with the BMW for a more fair comparison.
torque at the engine is not particularly relevant; it is the torque at the wheels that matter and that is determined, by the gearbox ratios and the final drive ratio.
what do you think would happen if you gave a jtd a jts's gear ratio's?
think about it guys.
