I agree and disagree, is it that bad to have the best of both. The only reason i bought a DSL was for the fuel economy, if the 335i was lighter on fuel i would have bought that. Infact most DSL drivers own their cars cause of the low fuel consumption. Would you really buy a DSL if fuel price wasnt an option?

0 - 100 in 3.9sec!!!!!
That could justify the R1m pricetag.
Ferrari's cost 4 times that and do 0 - 100 3.5 sec.

S55 vs N55
Stroke:
80mm vs 89.6mm
Bore:
89.6mm vs 84mm
The bore/stroke really sets this engine apart from the 335i (N55) engine and is nothing that a tuned 335i can compensate for. The engine's will act, feel and sound different.
Block:
Completely New and lightweight
Twin-wire arc-spray coating (instead of liners) in cylinder bores reduce engine weight
Turbo size is smaller than 1M turbos.
Maximum HP between 5500-7200rpm (should be 5700-7200rpm)
Maximum torque between 1800-5700rpm
"The turbos run at a maximum of 1.25 bar boost but often less, the electronic brain only cranking up to that level of pressure under high operating temperatures or at high altitude. It means the power and torque figures will remain consistent in the vast majority of conditions. As Vice President of engineering, Albert Biermann, explains, that means a standard M3/M4 will often be as fast on track as a tuned car with a claimed additional 50bhp but no extra leeway to continue to develop that power as operating temperatures soar."
S55 vs N55
From the info ive managed to gather, quite a bit of difference..

The main differences between the S55 remain be it vs. the n54 or n55.
The bore & stroke are the same between the n55 & n54 whereas the s55 is completely different, which was what I found and posted above.
The turbos are also smaller than the n54 turbos in the 1m.
The block due to different bore & stroke is being called all new, but yet to be seen if derived from an older NA motor.
The Discussions on the interweb are that the s55 is quite a big departure from the designs employed in the n54 & n55.
If you have more info on the n54 vs s55 will help but from my understanding the s55 is quite different.
Comparisons also made to the alpina n55 motor which show how even when modified the s55 is a better motor as it employs a high revving TC motor, making power almost until the redline, but with lower torque.
So all in all just comparing blocks, it is a very different motor.
