As for the engine lineup, why make any choises any different than what is allready available in the sedan? I could care less about turbochargers and diesels (maybe, depends on US regulations post-2007) as long as I get a sily-smooth 3.0L I6 with a six-speed manual.
Because BMW is on the low end of the horsepower curve in the price range right now. In 2006, 255hp is simply not going to cut it in the $40,000 class. Not when Lexus is packing 305hp and Infiniti is packing 290hp. 0-60 times may be on par with the heavier competitors, but if you look at 1/4 mile trap speeds, the 330i is way down compared to the Japanese.
This new coupe is going to ringing up in the mid $40,000 range at the register. That's not only 10 grand more than it's direct competition: the G35 Coupe, it's also in Corvette territory.
Speaking of the Corvette, the Z4 3.0i is 145 horses down there, and costs the same $45k after you pile on the options.
Also consider this: a 530i rings in around $50,000 well equipped. For the roughly the same dough, I could have a base V8 Infiniti M45 that would suck the 530i's headlights right out.
BMW needs to have a six cylinder power option that makes 300ish horses. It would make three model ranges (3, 5 and Z4) far,
far more viable. And they need to do it without raising prices much.
BTW: Why use the new turbo engie rated a 333HP when they allready have the M-Spec version that pumps out the same power? I'd much rather go with proven power than something new that is more likely to have problems.
The S54 motor in the M3 costs twice as much to produce as a "regular" NG6 motor, making it cost prohibitive. Besides, from a marketing standpoint, it would be a disaster; an M engine in a non-M product would send current M owners into a tizzy.
The turbo is a quick fix to the horsepower problem. I'd MUCH rather have a bored and stroked version of the current motor like the internet rumor mill suggested. But a many say there's no room between the cylinders to expand and a longer block would create packaging problems in the 3er and 1er.
