Seen these two powerplants tested by a magazine here in U.S. with a similar outcome. I've also had 2 of each engine in a 135 and 335, one each with N54 and one each with N55... The N55 cars were more fun to drive and had much superior overall power. Problem is now the new M235 is heavier than the M4. That's not good. Regular light limited production this time should keep pricing reasonable. This car should underut the M3 by $8-10k. Give us a 48-54k M2 and I'm sold. I'll buy 2,  ... We need something to smack down the CLA45 and a rumored 390 hp CLA45 S coming. |
Interesting thoughts on N54 and N55... thanks for sharing.
