Infiniti JX crossover revealed at Pebble Beach

After a month of teasers and tidbits, the Infiniti JX Concept was finally revealed in its entirety on Thursday in California, ahead of the Pebble Beach Concours d'Elegance. The seven-passenger, three-row crossover concept is expected to appear largely intact as the production 2012 Infiniti JX next spring. Styling cues were obviously borrowed from the Essence concept, but the JX also seems to have a bit of Volvo XC90 in the greenhouse and even a touch of Mitsubishi Lancer in the front grille aperture.

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.
