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.

Jaguar Lightweight E-Type makes a comeback after 50 years – 6 new Lightweights to be built

6 new Jaguar Lightweight E-Types on the way Even in 1963, car makers made ‘special editions’ of production cars, and one such car was the Jaguar Lightweight E-Type, a lightweight version of the then new production E-Type designed to take Jaguar racing. This was in the days before carbon fibre panels, so Jaguar built many of the body panels from aluminium and fitted an aluminium block version of the 3.8 litre engine from the production E-Type with 300bhp (55bhp more than the road car), fuel injection and a ZF 5-speed gearbox. The Lightweight E-Type wasn’t a spectacular success on the track, and Jaguar ended up building just 12 of the original planned run of 18.

Porsche Panamera diesel owners can boost the fun with TechArt power upgrade

The German Porsche tuning haus TechArt revealed a power-upgrade kit for the Porsche Panamera diesel. While the 30-hp bump from the stock 250 horses to 280 won't light the world on fire, the 37-lb-ft jump in torque, from 405 lb-ft to 442 lb-ft, is sure to be a kick in the pants. The 0-to-60-mph time drops by 0.1 second from stock to 6.6 seconds, but the top end is up 3 mph to 153 mph.
