Here's something you don't see often: a tuner car more faithful to a brand image than the product it's based on. Somehow the Porsche Cayenne-based RUF Dakara manages attractive, round 911-style headlights.

Renault has a history of building some fairly taut sporting versions of regular production econo-hatchbacks. The Renault Sport Mégane RS is no exception to the rule, bringing 250 turbocharged horses to the table.

You're probably asking what RUF is thinking, developing an electric sports car, but remember way back when you asked the same thing about that small startup in Silicon Valley. RUF might be onto something.

Still in concept form but now in real pictures instead of PR gloss, here's the Alfa's MiTo GTA. Those ludicrous exhaust pipes look even more enticing in the flesh!

The Frazer-Nash Namir by Giugiaro claims to be the world's fastest hybrid. The car unveiled in Geneva is a 187 MPH missile miserly enough to run on vapors. How fitting.

When we heard the Infiniti Essence Concept would feature custom Louis Vuitton bags, we made fun of it. A lot. But the car's now debuted at the Geneva Motor Show and it's gorgeous. Seriously.

Think you saw the Mitsubishi iMiEV Sport Air Concept before when it debuted as the iMiEV Sport? Think again. It's now gussied up with blue paint, "solar panels" and a crazy interior straight from Tron.

This is the Dacia Duster concept and it's bringing a totally original, unprecedented suicide-door sport activity youth-market crossover utility design with headlights stretching to the doors to Geneva. Yes, it's a rolling modern design cliche.

Take the oddly-shaped segment-bending BMW X6, add a bunch of carbon fiber doo-dads, lower it over deep-dish wheels and name it after a Mercedes-Benz racer. The result? The Lumma Design BMW CLR X 650 GT.
