Jaguar crossover concept (2013) the first teaser shot

What looks like a screen grab from Sin City is in fact our first official glimpse of the new Jaguar crossover. The jacked-up, coupe-like CX-17 is one of two new models on the way from Gaydon, the other being the ‘X760’-codenamed 3-series rivalling sports saloon. Argh, not another teaser picture… We don’t like them any more than you do, but in this case we’ll allow the Jaguar through the net.

Kia Forte

Kia has released renderings of its 2014 Forte model, known as the K3 in Korea and the Cerato in the European market, ahead of its debut at this year's Los Angeles auto show in November. The renderings show the Kia family tiger nose grille, while a rising line sweeps from the front to the rear, giving the car a much more aggressive stance than its predecessor. A steeply-raked windscreen and blacked-out side window frames, emphasized by a chrome strip around the side graphics, creating a more dynamic profile.

New BMW M3 and M4 engine secrets laid bare

BMW's M division has lifted the veil of secrecy on the inline six-cylinder engine bound for its upcoming M3 sedan and new-to-the-range M4 coupe and convertible, revealing a potent twin-turbocharged 3.0-liter direct injection gasoline unit that produces an official 424 hp at 7,500 rpm and what officials describe as "significantly more than 369 lb-ft" of torque. The newly developed engine, known under the internal codename S55 B30, shares its 84.0 mm bore and 89.6 mm stroke with BMW's standard turbocharged 3.0-liter in-line six-cylinder direct-injection gasoline mill, the M55 used across the German car maker's lineup, endowing the aluminum block unit with an overall swept volume of 2,979 cc. This represents a sizeable 990 cc reduction on the engine BMW's M division's new unit replaces, the S65.
