Peugeot teases Onyx supercar concept

Peugeot has teased a supercar concept dubbed the Onyx ahead of its world debut at this month's Paris motor show. The Onyx will be further developing the supercar concepts that we've seen the automaker unveil in the past – such as the SR1 convertible and the EX1 electric racer – and is likely to indicate Peugeot's future design language as well as that of the RCZ's successor. From the teaser images we can see that the Onyx has the classic supercar wedge shape with a cab-forward design and a rear spoiler that rises at high speeds.

Infiniti JX crossover revealed at Pebble Beach

After a month of teasers and tidbits, the Infiniti JX Concept was finally revealed in its entirety on Thursday in California, ahead of the Pebble Beach Concours d'Elegance. The seven-passenger, three-row crossover concept is expected to appear largely intact as the production 2012 Infiniti JX next spring. Styling cues were obviously borrowed from the Essence concept, but the JX also seems to have a bit of Volvo XC90 in the greenhouse and even a touch of Mitsubishi Lancer in the front grille aperture.

Rinspeed XchangE concept previews cabin of self-driving cars

Ever wondered what you'll be doing in your car once cars become driverless? We'd probably just sit in the back seat and read the financial section of the paper (on some kind of transparent tablet computer, of course) to see how our Tesla shares are doing and make small talk about the weather with our imaginary chauffeur named James in a faux British accent, asking him to pass the Grey Poupon from time to time. But unlike us, coachbuilder Rinspeed is actually taking the yet-to-materialize issue seriously, and at the upcoming Geneva Auto Show it will debut its XchangE concept.
