2013 BMW Z4 vs. Its Competition

2013 BMW Z4
Bengt Halvorson Bengt Halvorson Senior Editor

A decade ago, BMW and Mercedes-Benz has gone to six-cylinder base engines for their roadsters; now with better engine technology—especially turbocharging—they're returning to fours.

Like the Z4 28i, the Mercedes-Benz SLK 250 offers strong fuel economy, although the SLK tends to feel a bit bulkier.

The Infiniti G37 is also at the portly end of the scale, although its strong V-6 is an asset.

The Audi TT is more of a sports car in its current generation and is a lean-feeling alternative that costs less.

The Porsche Boxster stands as the most serious sports car in the group, and it's probably the top choice for those who also plan to take their car out on the track once in a while; the only disadvantage of the Porsche is that you get a little more interior noise.

Quick Specs
7.8
The 2013 BMW Z4 is spirited and purposeful, and balances fun and comfort quite well, but it's pricier than other roadsters.
8.0
The 2013 Audi TT RS is the star on track, but all TT models offer fun and efficiency, plus a welcome dash of style.
8.4
The 2013 Mercedes-Benz SLK is the least polarizing of the roadsters, but there's enough urgency to go with its elegant, mini-SL charm.

The 2013 Porsche Boxster is one of the most fun, stylish, and luxurious roadsters available.
