Wrap-up of this thread so far:
Engine
- 2008 - 2010 models have the twin turbo N54 engine
- 2011 models have the twinscroll (single) turbo N55 engine
Both are rated at 300hp/300tq and have similar performance. Stock vs Stock, the N55 has a slightly louder rumble. Especially on cold starts.
N54
- Twin Turbo setup
- Easier to get more power from pnp tunes
- HPFP Issue, check the numerous threads and sticky in General Discussion. Warranty for N54 engine HPFP has been extended to 10 years or 100,000 miles.
N55
- TwinScroll single Turbo
- Pnp tunes in testing, but not quite as much gains as N54 tune
- So far no confirmed reports of HPFP issue
- Supposedly reaches peak torque at ~200 less RPM than N54
Sport / M-Sport
- 2008-2011 models had the M-Sport option which included sport package + M Sport style 261M wheels, M door sills, and Anthracite (black) headliner.
Transmission
- 2008-2010 had the option of Steptronic or 6MT
- 2011 128i maintains Step or 6MT
- 2011 135i has the option of Dual Clutch transmission or 6MT
- 2011 128i Steptronic paddles are right side up and left side downshift instead of previous method of push for up and pull for down
Mirrors
- 2008-2009 have smaller mirrors
- 2010-2011 have larger mirrors
Colors
- 2008 model year was the only year to offer Sparkling Graphite Metallic
- 2009-2011 introduces Le Mans Blue Metallic available only with the M-Sport Package
- 2008-2009 offered Monaco Blue
- 2010-2011 Deep Sea Blue replaced Monaco Blue
Value Package
- 2011 models have the Value Package option which includes leather interior and i-Pod connectivity at no cost
2009-2011 models had the M-Sport option which included sport package + M Sport style 261M wheels, M door sills, and Anthracite (black) headliner.
and Increased top speed limiter and Shadowline exterior trim and M shift knob and M hand brake handle, and the M Steering wheel if you didn't order the Cold Weather Package.
Yes, M-Sport includes everything the Sport package has and adds the headliner, M door sills, and M Wheels. You can still get the Sport package alone for 2009-11 models but M Sport was/is only a $200 addition.
Some owners with '10/'11 models have retrofitted the smaller '08/'09 mirrors on their cars.
This means that a 2011 135i could have the m steering wheel, m shifter and m door sill along with 264( none m)wheels?
YES, I have seen this.
