BMW M3 Lime Rock Park Edition set for fall

The current generation of the BMW M3 has been with us since 2007. As it nears a refresh, the company built a limited run of 200 special M3 coupe Lime Rock Park Edition cars to celebrate the racetrack in Connecticut. Skip Barber, owner of Lime Rock, and BMW collaborated on the vehicle, which will only come in what BMW calls fire orange.

Concept Car of the Week: Mazda Ibuki (2003)

With the Ibuki, Mazda designers synthesized the most successful of the first generation MX-5's iconic elements and evolved their forms to make them even more memorable and simple. To do so, they used a strong geometric theme throughout the car inside and out: LED headlamps; front air intake; tail lamps; rear view mirrors; release handles and interior details down to the pedals – every shape follow the same oval theme. Zooming out, the silhouette – as well as the top view – is also oval, making the Ibuki look more like a toy than a car, which is a real bonus for a small roadster.

Jaguar F-Type R Coupe unveiled!

When Ian Callum speaks design, it doesn't feel entirely like he's speaking from a teleprompter, listlessly reading from a speech carefully combed over and picked apart by public relations professionals. No, Callum -- 59, and broadly Scottish -- speaks like an old, tenured college professor, a living institution at an institution, as if he's trying to inspire a troubled student. "Cmon," he seems to tell us, "this is how it's done." For Callum, the F-Type Coupe has been an "emotional journey" since he started 15 years ago at Jaguar.
