2012 Chevrolet Corvette upgrades focus on track performance

To keep up on the track with the Vipers and Super Snakes of the world, Chevrolet has upgraded the Corvette for 2012.

Only offered on the Z06 and ZR1 models, the package includes the tires, 285/30-19 in front and 335/25-20 rear, and lightweight aluminum Cup-style wheels in satin black or machined finishes.

Honda would like to remind you that while journalists have spent the last few years fretting whether the Big H has "lost its way," the company has quietly launched, shelved, resurrected, and all but waited out its plan to dominate the business-jet skies, which we are to assume are less friendly than United's. The HA-420 HondaJet has been kicking around for more than 10 years now, but the very first production-ready plane just rolled off the assembly line in Greensboro, N.C., this week -- and, Honda promises, the $4.5 million business jet should be delivered in the second quarter of next year. Honda began taking orders for the jet in 2006, but the long recession squashed the market for private jets.
