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.

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.

David Brown Automotive Speedback UK debut at Goodwood Festival of Speed (video)

The David Brown Automotive Speedback (above) gets its UK debut at the Goodwood FoS The reveal of the David Brown Automotive Speedback was a pleasant surprise. We’d expected the Speedback to be yet another take on the E-Type – based as it is on the underpinnings of the still very able Jaguar XKR – but instead it was a proper classic GT car that looks much like a classic Aston Martin from the 1960s – think DB5/DB6. Glorious though a DB5 or DB6 is to own, a lot of the time they’re more a work of art to covet than a car you can drive every day.
