The new BMW Z4 has taken on a retractable hardtop, several hundred pounds of weight, and some useful new high-tech equipment, and altogether it's a joy to drive.
But it doesn't feel nearly as edgy as former versions did.
The new Z4 is now heavier than the Mercedes SLK; while the SLK used to feel heft in comparison, they're now on equal footing.
The new Audi TT has a much more aggressive feel, with rear-biased all-wheel drive, than the models they replace, and it arguably comes across more like a full-fledged sports car than the Z4.
Those who want a true sports car should consider the Porsche Boxster, which just this year got an all-new engine lineup.
The Nissan 370Z is another possibility, though the Nissan Z has a loud, sometimes uncomfortable cabin with generous helpings of road and engine noise that don't make it a good traveling companion.
The Z4 weighs about 1,000 pounds more than a Mazda MX-5 Miata, and you can now get two Miatas for less than a base Z4; those who want that lightweight roadster feel might want to keep it basic.
