Audi Sport Quattro Concept grips the 2013 Frankfurt Motor Show

Audi has revealed the Sport Quattro Concept here at the 2013 Frankfurt Motor Show – 30 years after it first showed the original Sport Quattro at the same Frankfurt show in 1983. A retro-inspired but thoroughly high-tech concept, it packs a 700hp V8 plug-in hybrid engine for explosive performance that has an unexpected green twist, too.

2015 Mercedes S-class Coupe: The flagship has landed

Mercedes-Benz's long history building dramatic flagship coupes started with the 1952 300 S, considered a “car for the world's elite.” The 220 S Coupe followed in 1956, and the elegant W111/W112 coupes ran from '61 to '71. Over the years, the 280 SE 3.5 Coupe, SEC coupe, S600 Coupe and CL class all added to Mercedes' reputation for building gorgeous, sought-after coupes. Now comes the new S-class Coupe, making its public debut at the Geneva motor show March 4 and arriving in U.S.

Range Rover Sport (2014) [w/Gallery]

This is the new, second-generation Range Rover Sport, unveiled at the New York Auto Show. While the first Sport – introduced in 2005 – was a tentative toe in the water for a second Range Rover model line, this new model forms the center of a three-model range, between Evoque and full-fat Range. At 4,850mm long it's 62mm longer than the car it replaces but 149mm shorter than the new Range Rover, while its wheelbase has grown by 178mm to increase rear access – particularly important as there's now the provision of a pair of occasional seats in a third row.
