The 1967 Shelby GT350 and GT500 are here!

The 1967 model year saw the introduction of a redesigned Ford Mustang that was slightly larger and heavier than the first pony cars. Bloat, it seems, has been around forever. But it wasn't all bad: '67 'Stangs got those crisp, fastback lines immortalized in "Bullitt" and yes, the remake of "Gone in 60 Seconds." Plus, the Mustang's increased size meant you could wedge a big-block motor under the hood, and that's exactly what Shelby American did with the GT500.

Mercedes CLS (2011 / 2012) spied undisguised

Mercedes CLS 2011 Spy shot The Mercedes CLS was the first - and some would say still the best - interpretation of a four door swoopy-coupe. It set the benchmark for cars to follow and made the genre hugely desirable. We now have everyone from VW to Porsche and Aston Martin to Jaguar producing 4 door coupes, with Audi joining in with the Sportbacks and BMW about to put the Gran Coupe in to production.

Video: Track-day fun in the Lexus LFA

As promised, the third installment in our supercar video extravaganza--after the Chevrolet Corvette Z06 and the Porsche GT2 RS--gives you the lowdown on the hyperexotic Lexus LFA and its insane 552-hp V10 powerplant. Best described by senior editor for motorsports Mac Morrison as "shrieking like a melting witch," the Lexus LFA emits a wail unlike anything this side of a Formula One racer, and its performance isn't too far off that mark, either. Check out the walk-around and some on-track fun, then come back for the VBox lap on Friday.
