I drove the 135i again and this time it wasn't as much fun... I think it's down to the loss of sensation of speed, you feel it's fast but it's so incredibly smooth it feels slightly detached. Driving the non-turbo charged model you get to wring the engine out more as it likes to rev in the upper end of the rpm band. For some reason I like the ability to rev the engine more than I like just having a bunch of artificially aspirated torque under my right foot. I'm sure with the Camaro V8 I'll be able to do all the engine straining I want but still having the naturally aspirated power too.
