I didn't say anything about power. My point was about torque. Guess what makes acceleration? Not HP.

A 335d would therefore be quite a bit more expensive than a 328i.
Diesel engine needs larger displacement to produce similar power. Likewise, a 4-cycle engine needs to be larger than a 2-cycle for comparable power.
This is most easily verified by studying performance numbers.
I do agree with Dunderhi, however, that in a typical city driving diesel will sure enough "feel" quicker, as RPM is typically low. Not so much on an autobahn though (or some faster interstates). There, torque loses its glamour and anything above 60mph is all about true power (where 335d would compete with 328i, not 335i). 335i leaves the diesel in the dust.
Sorry, I'm just a torque junkie. I've never lived in an area where I could wind out a car more than a gear or two. I love stomping on the throttle and gaining 20 MPH in the blink of an eye accompanied by that shove in the back.
