The Z4 has undergone a facelift, reducing the ungainly styling it first dawned early in the decade.  The new roadster, BMW’s only two-seater, now features a retractable hardtop and a 3.0 L inline-six.  A lightweight aluminum chassis and high-precision direct-injection add efficiency in addition to high-performance, reducing carbon emissions and maximizing fuel economy.
