Unveiled at the Los Angeles show, this four-wheel-driver runs a more powerful version of the Cayenne Turbo’s twin-turbocharged 4.5-liter V8 engine, putting out 521 hp at 5500 rpm and 531 lb-ft of torque between 2750 and 3750 rpm. That is a 71-hp and 71-lb-ft improvement on the standard Cayenne Turbo. It makes this new S the second most powerful road car Porsche has ever placed into production after the 5.7-liter, 605-hp V10 Carrera GT. It’s also enough to lower the big, 5200-pound SUV’s 0-to-62-mph time from 5.6 seconds to 5.2, as well as provide it with a 50-to-75-mph fifth-gear time of 5.4 seconds.
