Ferrari Enzo successor to make 920 hp

About a decade and a half after Porsche eschewed its lightness-and-small-displacement strategy and built a five-liter sports racer to take down Ferrari at Le Mans, a different sort of war kicked off between the two marques: a battle for supremacy in the super-supercar market. In 1984, Ferrari built a radically modified twin-turbo 308 GTB with an eye toward Group B road-racing rules. Porsche countered the resultant 288 GTO with the mighty 959, which launched at about the same time as the 288's successor, the practically skeletal and infinitely loopier F40.

Novitec Alfa Romeo 8C Spider adds boost for a sensuous 600 hp

Novitec has laid hands on the near-perfect Alfa Romeo 8C to create the 8C Spider Kompressor, a car the tuner claims is the “most powerful street-legal Alfa Romeo of all time.” Heady words, but they're nicely backed up by a supercharged version of the 4.7-liter Alfa V8 cranking out 600 hp and 434 lb-ft of torque. That's up from approximately 450 hp and 346 lb-ft on a stock Alfa Romeo 8C Competizione. Tweaks supporting the force-fed mill include a water-to-air intercooler, custom injectors and revised fuel and ignition mapping, plus a variable stainless-steel exhaust system.

2011 Ford Shelby GT500 Mustang gets more power, loses gas-guzzler tax

The 2011 version of the Ford Shelby GT500 Mustang carries a supercharged 5.4-liter V8 that weighs less, delivers more power and uses a unique spray-coating process that eliminates the need for cast-iron liners in the aluminum cylinder block. The 550-hp Shelby GT500 also loses something from the previous model--it's gas-guzzler tax. Ford says the new Shelby GT500 will deliver 23 mpg on the highway and 15 mpg in the city.
