2015 BMW Z4 vs. Its Competition

2015 BMW Z4 Pure Fusion Design
Nelson Ireson Nelson Ireson Senior Editor

A decade ago, BMW moved to six-cylinder base engines to power its roadsters; now with better technology, it can accomplish the same–or more–power with turbocharged four-cylinders.

The Porsche Boxster is the sportiest competitor in the segment, and while you may deal with a little more interior noise, it's the best option for someone looking for occasional track use.

The Infiniti Q60 is comparatively bulky, but comes with a rear seat and a willing V-6 engine.

The Audi TT feels lean and sporty–and it costs less, too–but it comes standard with front-wheel drive and less power than the BMW.

There's also the Mercedes-Benz SLK 250, which feels bulkier than the Z4, but offers similarly frugal fuel economy numbers.
