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.

Audi A3 Concept (2011): first pictures

Audi has released first sketches of the Audi A3 concept, ahead of its debut at the 2011 Geneva motor show. Audi is previewing the upcoming A3 with this saloon concept. It's powered by the fan-favourite five-cylinder turbocharged engine in 408bhp specification. Quattro four-wheel-drive and a seven-speed S-tronic double-clutch transmission complete the powertrain.  Sizewise, the new A3 saloon is 4440mm long, 1840mm wide and 1390mm high.  That's longer than the current A3 Sportback (4.3m) but shorter than the current VW Jetta saloon (4.64m). The new concept is slightly wider and lower than the current A3.

Autoweek archives: Porsche, same as it ever was? Not quite

In July 1997, Autoweek introduced its readers to the next-generation Porsche 911, the Type 996. Hot off the Frankfurt motor show release of the redesigned Type 991 2012 Porsche 911, we thought it might be fun to look at how much the iconic German sports car has changed since then. While it looks like not much has changed, the Type 991 is a brand-new car.
