Lairier, quicker, and just plain better, the 2013 Porsche Panamera GTS was unveiled this week at the L.A. Auto Show. And now it's on video doing its thing, on track--with all four seats filled.

if you've been looking for a true four-seat hoonage machine that doesn't bear Mercedes, Cadillac, or BMW badges, this may be your answer. And with 430 horsepower pumping from its 4.8-liter V-8 engine, PDK transmission, and Porsche Active Suspension Management (PASM), it's an answer that's at once higher-tech and likely more comfortable than many of the alternatives.
