2009 BMW Z4
The most obvious change to the Z4 when it debuts at the Detroit auto show in January will be its more conventional styling. The polarizing influence of Chris Bangle has been greatly toned down, although the trademark “Bangle butt” remains. Overall, the lines look similar to those of the BMW 1-series, though some cues carry over from the new 7-series as well.
The other plainly clear difference is the absence of a cloth top. In lieu of separate convertible and coupe variants, the new Z4 features a retractable hardtop that disappears at the touch of a button within 20 seconds. Less clear from the pictures are the Z4’s stretched dimensions. The new car is nearly 6 inches longer and a half an inch wider than its predecessor. BMW says this growth affords passengers more comfort and space inside. The larger size, coupled with the addition of the power-operated hardtop, contribute to a weight increase of roughly 500 lbs in a fully loaded, automatic model, to a claimed curb weight of 3494 lbs.
Changes inside are a bit subtler. The biggest news is the availability of iDrive for the first time in a Z4. Overall, the interior appears to have moved decidedly more upscale, especially when equipped with the optional leather-wrapped dash. BMW says it focused on increased practicality as well. Door openings are larger for easier ingress and egress, and there are new storage compartments throughout the interior. In the trunk, a mid-gate separating the roof compartment can be folded down for more luggage. An optional winter package adds a pass through to the cabin, allowing room for up to two full size golf bags with the top up, BMW says.
