As for the straight cylinder configuration, its just tradition. And just posted the motor weights, which is pointless since you have to put a motor into a chassis eventually. The E46 M3 coupe weighed 3,415 lbs, while the E92 3,704 lbs -- so much for the 15 lbs lighter.

As for this shit, the M7 is not realistic -- The closest you'll get is 760 twin-turbo V12. Alpina does have the best working relationship with BMW, but it is an independent business and is an aftermarket company, the B7 is the only Alpina you can buy directly from BMW. The relationship is exactly the same as Ford selling the GT500. Just like how you don't see every Shelby model being sold in a Ford dealer, you don't see every Alpina model being sold in BMW dealers (B3 BiTurbo / B5 BiTurbo). The European tuners (Alpina, Hamann, AC Schnitzer, Hartge, etc.) are much more respected & much larger when you compare them to anything here in the states, whether it be Cobb, Vishnu or Burger Tuning. Dinan is essentially North America's version of Alpina (it's actually specific to the North American BMW market), you can walk into specific BMW dealers (found here: and buy a Dinan-tuned BMW & have it serviced by that same dealer. The minute you buy a Alpina/Dinan BMW, it no longer is under BMW's warranty but instead the independent aftermarket company's.
note: f01 740i is also a n54
