The new BMW Z4 is a joy to drive, but it's not as lithe as past versions.
The same is not true for the Audi TT, which has become more sports car-like in its latest edition, with a leaner body and rear-biased all-wheel drive handling its ample turbo power.
The Mercedes-Benz SLK grows more masculine and composed in its current generation, and the Z4 is now in its weight class, so the BMW's handling edge has largely disappeared.
Those who want a true sports car should consider the Porsche Boxster, which has direct-injection engines and a new dual-clutch transmission option to match its stellar handling.
And for luxury loafing, the hefty Infiniti G37 Convertible is a great addition to the ranks, with a handsome body and quick-folding top increase appeal to its rosewood-trimmed interior-and a throaty 325-hp V-6 and seven-speed automatic or six-speed manual bringing enough performance to fit the class.
