This new roadster introduces a first-ever retractable hardtop. The newly redesigned BMW iDrive has a more intuitive interface with an 8.8-inch display screen with high-resolution graphics. Dripping with new technology, the Z4 will easily connect your iPod, iPhone or MP3 player. With dynamic driving control, drivers can opt for the sport button for a quicker engine response as well as reduced power steering assist. Bi-Xenon headlights follow the direction of the wheels, turning around bends, allowing the driver to see more of the road faster, enabling a safer ride. Worried about driving in Arizona’s rainy season? With the enhanced braking system, the automatic windshield wipers trigger the brake-drying feature. Starting at $46,500. www.bmwusa.com.
