AutoWeek office swag: Mazda rotary-engine keychain with realistic motion

When I got the keys to our long-term 2011 Mazda 5 last week, they came with a surprise--this aluminum-and-brass keychain in the shape of a rotary-engine housing, complete with moving rotor. The rotor doesn't just rattle around or spin in a circle. Thanks to a thumbwheel on the back of the housing, coupled with a timing gear and offset crank journal, the thing actually moves in an approximation of epitrochoidal motion just like a real Wankel.

Gemballa Mirage GT Carbon Edition revealed

Gemballa Mirage GT Carbon Edition Uwe Gemballa and his team are probably the world’s best Porsche Carrera GT Tuners. There have been a number of tuned and pimped versions from them in the last few years (you wonder when they’re going to run out of donor cars  – there were only 1270 ever made), but this one looks particularly good. Based on a standard donor Porsche Carrera GT, the Gemballa Mirage GT Carbon Edition gets a power increase of around 50bhp, taking it to 670bhp (not as mad as some of the Gemballa Carrera GTs have been) and 470lb/ft of torque.

Peugeot SxC concept

Peugeot have revealed pictures of its latest concept ahead of its Shanghai launch. Dubbed the SxC, the show car has been designed solely at the Peugeot Style Studios in China. Sitting atop 22inch wheels and weighing in larger in every dimension than a Range Rover, the Peugeot SxC is an 'impressive size' according to Peugeot, but also harks back to design elements of previous concepts such as the BB1, EX1 and SR1.
