Check out the BMW Z4 2011. It may not be the best car to drive, but it is the best car to ride. Competitors offer superior performance, but for the supreme all-around roadster available, choose the blue and white roundel. BMW slotted the two-seat Z4 as a direct competitor to the high-performance but low-comfort Porsche Boxster and Lotus Elise. But the Boxster and Elise kept getting better, so BMW decided to edge its competition via a different approach. However, just because the BMW Z4 is a runner-up on the track does not mean it has no chops. The six-cylinder powerplant is one of the best, with a seductive soundtrack and an even circulation of power and torque throughout the rpm range. A standard six-speed manual gearbox quickly routes power to the two rear wheels, which do an worthy job of keeping the 3,252-lb roadster convertible grounded. The Z4 offers practicality and interior grace in a segment renowned for not having much of either. It has a useable rear trunk with a pass-through feature, commendable legroom and a finely crafted interior with sumptuous styling and a superb user interface.
