Nissan's DeltaWing goes for a ride at Sebring

The Nissan-powered DeltaWing race car was on-hand for a few laps at Sebring this weekend, and the funky-looking speedster made it around the 3.7-mile track without incident. Granted, it was at about half race speed, but it was good to see the Nissan out on four wheels— narrow as some of those wheels might be. The DeltaWing sports a direct-injection, 1.6-liter turbocharged Nissan engine making about 300 hp.

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.

Commute times increasing

COMMUTING times are starting to creep up after falling back during the recession, a new study has shown. Research by the TUC union revealed that men in their early 40s spend longest getting to and from work, at an average of more than 67 minutes a day. Commute times for women peak in their late 20s at 54 minutes and then start to fall as they get older, said the report.
