I would not let this scare you away as I cannot say enough good things about this little motor. There are several post on how BMW underrates the HP & Torque of their motors and I believe it. The N20 will keep up with a lot of V6s out on the market and getting great fuel economy while doing it. My wife consistently gets 26 mpg in mixed driving condition in comfort mode.
If you are looking for a great sounding BMW motor, the N20 is probably not for you. I myself prefer to keep the noise outside the car  |
10 years from today people will complain how bad the next generation engine when compared to N20. It takes time to get recognition for any new comers like actors, singers...engines are not exception to this rule.
