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.

India's National Institute of Design

The National Institute of Design (NID) in Ahmedabad is hidden in the greenery behind an iron gate in the crowded streets of the biggest city in the Indian state of Gujarat. There are no car manufacturers here, nor is there any particular tradition of design in general. But for almost half a century this has been the main school to enrol in if you want to become a car designer in India.
