Though it might seem like 2010 is just beginning, that’s not stopping BMW from releasing information about its upcoming 2011 model lineup. Although we already knew about some heavily revised or all-new models, BMW spilled the beans on the rest of its 2011 revisions today, which include some new transmissions and a race-tuned suspension package for the M3.
The changes are otherwise mostly related to packaging shuffles, although all models formerly equipped with BMW’s twin-turbo six-cylinder will get the new single twin-scroll turbocharged version of that motor. This includes the 135i, 335i, X5 and the new 5-Series.

Models not listed below, with the exception of the X5, are unchanged. BMW says it will release information about the refreshed X5 at a later date. Most 2011s will go on sale in the second quarter of 2010.

1-Series
Mechanically, the 135i adds a seven-speed dual-clutch transmission in place of the outgoing six-speed automatic. The 135i gains the aforementioned twin-scroll turbocharged six-cylinder. 128is are unchanged and will continue to include the six-speed automatic as an option.

Feature-wise, the 1-Series now gets no-cost leather trim and iPod adapter, a newly optional heated steering wheel, an upgraded Harman/Kardon audio system and a revised Convenience Group. The 2011 1-Series does not see a price increase.

3-Series
In addition to the changes already announced to the coupe, 335is and convertible versions of BMW’s popular 3-Series, the sedan and wagon receive a handful of minor upgrades. Unlike the 1-Series, however, the 3-Series retains its optional six-speed automatic transmission.

BMW’s diesel-powered 335d sedan will be newly available with the $3,750 M Sport Package and all models get a newly available Harman/Kardon audio system. All models get no-cost leather seats and iPod adapter.

Pricing for the sedan starts at $34,025 for the base 328i sedan.

M3
BMW’s high-performance M3 adds a new Competition Package for 2011. The package adds a 10 mm lowered suspension, 19-inch alloy wheels with a greater offset to increase the track width and revised Electronic Damping Control and stability control. The package is available on sedans and coupes for $2,500.

Base M3 sedans start at $56,275 for the new model year.

7-Series
BMW added several new models to the 7-Series, including the turbocharged six-cylinder 740i and 740Li, the Alpina B7 and the ActiveHybrid 7, the automaker has added a few new standard features to the mid-level 750-line. The previously optional Convenience Package, which included soft close doors, electronic trunk opening and closing and Comfort Access keyless starting, is now standard.

The entry-level 740i starts at $71,025, about $10,000 less than the 750i.

Z4
In addition to the new Z4 sDrive35is, other Z4 models gain a newly optional M Sport Package that includes styling and suspension upgrades for $3,500-3,900 depending on model.

The entry-level Z4 sDrive30i will list from $46,875.

X6
BMW has added an eight-speed automatic transmission to its X6 crossover. The transmission is added to both the six- and eight-cylinder models, reducing the time it takes to reach 60 mph by 0.1 seconds on the xDrive50i and 0.2 seconds on the xDrive35i.

Otherwise, the automaker has lightly juggled the X6′s option packages and discontinued the availability of heated rear seats and a ski bag.
