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.
