The feature list in the BMW Z4 is pretty extensive and enough to satisfy tech-savvy shoppers—provided the right option boxes are checked. Dynamic cruise control, HD radio, and xenon headlamps with cornering lamps are all standard, but items like satellite radio and a USB port are optional, as are Bluetooth and smartphone integration. Bluetooth, for instance—standard on many inexpensive cars—is only offered as part of a $3,900 BMW Assist package. The available premium sound system gets 14 speakers and 650 watts, and the base system has ten speakers and subwoofers, though our editors aren't very impressed with its top-down sound.
The optional navigation system includes iDrive—in its much-improved fourth-generation form—along with an 80-gigabyte hard drive-15 gigs of which are partitioned for personal music storage.
Price can be a sore point. The add-on features of the 2011 Z4 can take it from expensive roadster to near-exotic prices; tacking on the Sport Package and Cold Weather Package to the base car pushes its price to the $50,000 mark, while a completely optioned turbo Z4 zips past $70,000.
Overall, the Z4 is a far more expensive proposition than in the past, with a base price that's higher than the previous-generation, top-of-the-line Z4 M.
New this year is an M Sport Package, which combines the Adaptive M Suspension, exclusive exterior colors, an Anthracite headliner, and an M Sport steering wheel.
