While the latest Z4 boosts its gas mileage with the new turbo four, it's not quite as nimble as previous versions.
Nevertheless, it remains one of the most lithe options in its class, as competitors like the Audi TT, Mercedes-Benz SLK and Infiniti G37 have added bulk or started from larger bases.
Aside from the Porsche Boxster, it's the most serious sports car in the group, though each of the others offers some benefit in comfort (SLK), price (G37), or all-wheel-drive ability (TT).
The Boxster's sporting purity outshines the Z4's, but at the expense of a noisy cabin and a soft top.
