The Z4 comes exclusively with 6-cylinder power and offers a choice of four transmission types. Two models are offered: the Z4 roadster 2.5i; and the higher-performing, more extensively equipped Z4 roadster 3.0i.
The X5 Series got an extensive round of product enhancements last year. The changes included a new all-wheel drive system, xDrive, that adjusts front/rear torque proportioning according to road and operating conditions. There are two X5 models: the X5 3.0i and the X5 4.4i. The newest X5 4.4i sports an even smoother, more potent 4.4-liter V-8. It puts out 315 hp. The X5 3.0i keeps the same 6-cylinder engine as before.
The X3 stays pretty unchanged from its introductory year. BMW's 2.5- and 3.0-liter inline 6-cylinder engines are available. The X3 3.0i boasts 225 horsepower while the X3 2.5i offers 184. Both models come standard with a six -speed manual transmission. A five -speed automatic transmission is available as an option.
The new 750i and long-wheelbase 750iL will use a 4.8-liter Valvetronic V-8 capable of 360 horsepower and 360 pound-feet torque. The only engine left unchanged is the 442-horsepower V-12 in the 760i and 760Li.
With the introduction of the all-new 6 Series Coupe, an icon is reborn. Much like the original, the new 6 Series Coupe will be noticed first for its looks. The styling is bold, purposeful, dynamic and elegant all at once. The 4.4-liter V8 engine features 325-horsepower and 330 lb-ft of powerful torque at 3,600 rpm. The BMW 645Ci covers the sprint from 0-60 mph in well under six seconds.
The new 5 is a roomier car: Riding on a wheelbase 2.3 inches longer than before, these new Sedans are 2.6 in. longer and 1.8 in. wider than their predecessors, as well as 1.3 in. taller. The new 5 Series consists of three models, each powered by its specific engine. The 525i Sedan continues with the engine of its predecessor, the fuel-efficient 2.5-liter, 184-horsepower inline 6-cylinder unit. The 530i Sedan again offers a step up in 6-cylinder power (3.0 liters, 225 hp) and additional standard equipment over the 525i. The 545i Sedan derives its new model designation from theValvetronic engine first introduced in the 7 Series: a 4.4-liter V8 delivering 325 hp.
The range of ten 3 Series models is unchanged. The heart of the 3 Series' appeal remains its unique concept: each model is compact and tightly dimensioned, with short overhangs, a relatively long wheelbase, and wheels/tires that fill out their fender openings with serious road adhesion; every model is powered by an acclaimed inline 6-cylinder engine that delivers not merely strong, but also aesthetically satisfying performance. The 325 models' 2.5-liter unit generates 184 horsepower; the 3.0-liter of 330 models delivers 225 hp
