Up front on the 2009 BMW Z4 wide double-kidney grilles establish an aggressive face. Out back, the tail is cleaner and more elegant than the current Z4's, featuring simpler, wraparound taillamps with attractive lighting effects. The biggest change of all, of course, can be found in the roofline. As was the case in the 3 Series, the soft top has been retired in favor of a retractable metal roof. There's a subtle "double-bubble" effect evident when it's in place, and its use reportedly improves outward visibility with the top up. 20 seconds is how long you need to wait for it to raise or stow. European models have three engine selections, and the 2009 BMW Z4 employs BMW's ridiculous new naming scheme, as first seen on the X6. The Z4 sDrive23i is probably Euro-only, powered by a 2.5L inline-6 making 204 horses via a six-speed manual or automatic.
