Cadillac ELR

Cadillac has revealed the ELR: a production version of the highly-acclaimed Converj concept revealed at the 2009 NAIAS in Detroit. The new luxury coupe will be equipped with extended-range electric vehicle technology – essentially a T-shaped lithium ion battery powering an electric drive unit mated to a a four-cylinder engine-generator, which propels the car when the battery's energy is low. "There's no mistaking it for anything but a Cadillac, an aggressive, forward-leaning profile and proportion showcases a uniquely shaped, modern vision of a personal luxury 2+2," said Ed Welburn, GM vice president, Global Design. Welburn also stated that the Converj concept sparked the idea of combining the desirability of a grand touring coupe with electrification.

Mercedes GLA Concept: OFFICIAL

Aimed at cars like the BMW X1 and Audi Q3, the GLA is a good-looking compact SUV that carries much of what’s good about the new A-Class, raises its ride height, adds a few butch bits and creates a car that will probably have more appeal for owners of the old A-Class than the new A-Class does. The GLA heading for the Shanghai Motor Show sports a 2.0 litre turbo with 208bp, 4MATIC and a 7G-DCT gearbox – which we guess makes it a GLA 250 – and sports something new – laser headlights that function as projectors. The GLA features a pair of cameras on the front of the roof rails that can take 3D HD images and can be removed if you want to use them for mountain biking or jet-skiing or whatever floats your sporty boat.
