New Reveal : 2010 BMW Z4

Finally, after all the spy shots, BMW has finally released some official pictures and information of the new Z4. This new generation is the first Z4 to have a retractable hardtop. So it's two models in one, a coupe and a roadster. The new Z4's lightweight aluminum roof takes just 20 seconds to open and close.

With the heavy retractable metal roof, the new Z4 is considerably heavier than its predecessor. It sits on a longer wheel base, has a longer hood and larger wheel arches. It's also the first Z4 to have BMW's iDrive system, which controls all entertainment, information, navigation and telecommunication functions. So the new Z4 is aimed closer to being a highway cruiser than a sports car.
As for design, this Z4 is following its other Bimmer brothers with the huge grill like in the 7-sires. And the headlights are inspired by the 3-sires. Along with the wide wheel arches on the side, there are some muscular line to give it an aggressive look. At the back, the aggressive lines continue on the bumper, but the tail-lights have a much cleaner look than its predecessor.
Like all Z4s in the past, this Z4 has a simple cabin. Although it now has iDrive, but it can be hidden away in the instruments panel when it's not in-use. The new interior design, has some fascinating HVAC controls, which are pretty easy to use.
Engine line-up for this generation includes three, starting off:

Z4 sDrive23i, which is the cheapest model here. It's powered by a 2.5L inline-6 with 204hp connected to either a 6-speed manual or automatic.

Z4 sDrive30i. It's powered by 3.0L inline-6 with 258hp and 228 lb-ft of torque connected to the same transmissions as the sDrive23i. 0-60MPH comes in 5.8 seconds and the top speed is 130MPH (150MPH when equipped with the optional Sport Package).

Z4 sDrive35i, which is the top model. It's powered by BMW's award-winning new 3.0L twin-turbo inline-6 that develops 306hp. 0-60MPH comes in 5 seconds flat, and a top speed of an electronically-limited 130MPH (150MPH with the optional Sport Package). This engine is connected to a 6-speed manual, or an optional new 7-speed dual-clutch automatic with paddle shifters on the steering-wheel.
No word yet on the Z4 M, but the M version is likely going to follow end of 2009. No word yet either on prices, but we should hear a word from BMW at the Detroit Auto Show, where the Z4 will have its world debut over there.
