Infiniti Essence

PEBBLE BEACH, Calif.--The Pebble Beach Concours d'Elegance is a great place to see a flawlessly restored 1934 Rolls-Royce Phantom II. But the event also features plenty of the latest cars, too.

Attendees en route to the classic car show's awards ceremony Sunday were funneled past a stable of concept cars from many manufacturers at the prestigious golf course near Monterey, Calif. The sixtieth red Ferrari in a single day can seem a bit ho-hum as it rolls past, but there's still plenty to catch a car enthusiast's eye among the concept cars. The models range from thought experiments to real products.

This shot shows the Infiniti Essence, a luxury concept with a 600-horsepower 3.6-liter engine hybridized with a battery. Its drivetrain and styling are expected to be incorporated into future Infiniti models. The car features custom-fitted Louis Vuitton luggage.
