The new BMW Z4 was revealed in December 2012 and will go on sale in March 2013, marking 80 years since BMW first introduced the roadster concept. BMW's only current two-seat convertible, the new Z4 now includes an entry-level sDrive18i model and offers a more sophisticated and well-appointed Pure Traction Design package than previous Z4 versions. The updated Z4 will be available at a range of price points and power outputs.
