X5 / BMW model changes for 2009/2010

[LeMansX5]

X5: Like the 3-series, the X5 gets the 265-hp, 3.0-liter turbo-diesel engine, which is legal in all 50 states. The diesel X5 will be badged the X5 35d. In mid-’09, it’s likely that BMW will introduce an M version of this sport-utility vehicle.

Z4: The current Z4 sports car remains in production until early ’09 and will then be replaced by an all-new model that features a retractable hardtop in place of the current car’s folding softtop. BMW likely will offer naturally aspirated and twin-turbo 3.0-liter inline six-cylinder engines, making about 230 and 300 horsepower, respectively. The slow-selling Z4 coupe (along with the M version of the coupe and roadster) will go quietly to its grave.

3-series: The sedan and wagon versions of BMW’s bestseller get an exterior makeover that consists of a new hood and revised front and rear fascias. Models fitted with iDrive get the latest update of the system. The sedan also will be available with a 265-hp, 3.0-liter inline six-cylinder turbo-diesel engine for the first time in North America. The coupe and convertible models soldier on unchanged.

7-series: A new version of the range-topping sedan should arrive here in the first quarter of 2009. Available in both long- and short-wheelbase forms, its new styling is a lot less polarizing than was its predecessor’s. Underhood is BMW’s 400-hp, twin-turbo 4.4-liter V-8 that debuted in the X6. Expect the 750i to be priced similarly to the outgoing model and feature the latest, greatest version of iDrive and a more sophisticated active steering system. The V-12–engined 760Li departs, at least for the time being.

Unchanged: M3, M5, M6, X3, X6,
1-series, 5-series, 6-series.

Dead: Alpina B7, Z4 coupe, Z4 M.
