The tragically named Z4 sDrive35i features a twin-turbocharged, 3,0-liter inline-six that outputs 300 horsepower. The lesser Z4 sDrive30i features the same 255 horsepower 3.0-liter inline-six as the current model.
Putting that power to the road is a six-speed manual transmission or, in the case of the sDrive35i, a seven-speed double clutch transmission (DCT).
The Z4's new creased hood helps to make the new roadster look much longer than the current model. In fact, the new model shares the same wheelbase as the current Z4 and is only 5.8 inches longer from nose to tail.
While the new Z4 looks good from almost every angle, we think the head-on view looks a bit cross-eyed. The new headlamps and wider kidney grilles make the Z4 look lower and wider, although it's actually equally wide and slightly taller than the current Z4.
View from the side, the Z4's profile more or less remains intact. The less pronounced "duck tail" is much more visible from this angle and the rear end takes on a slightly Porsche Boxter-esque downward slope.
Adaptive M Suspension with Electronic Damping Control
The aforementioned Sport Package includes the Adaptive M Suspension with Electronic Damping Control which allows the Z4's digital brain or the driver to adjust the characteristics of the suspension on the fly.
Dynamic Drive Control allows the driver of the new Z4 to choose the drive characteristics of the car. In addition to changing damper forces on the Adaptive M Suspension, DDC also conditions the responses of the gas pedal, the power steering, and the response thresholds of Dynamic Stability Control. And if the car is fitted with either sport automatic transmission, the adaptive gearshift logarithms are adjusted.
