KTM X-Bow – want a drive?

KTM X-Bow 'Drive Orange' track days at Brands Hatch and Silverstone KTM is an Austrian Motor Cycle manufacturer which has woken up to the possibilities of making a four-wheeled creation, and has been busy building and refining the X-Bow in collaboration with Dallara and Audi. Featuring a 237bhp, 2.0 litre Audi  TFSi unit – and coming in at a bit under £50,000 for the street version – its low weight (790kg) gives it supercar acceleration of around 3.7 second 0-60mph. There is even talk of a 380bhp version, which will put it up there with the Ariel Atom V8 we reported on recently.

VW to intro Passat BlueMotion Concept at Detroit auto show

While performance heads are anxiously awaiting the North American debut of the hot-heat Mk VII Golf R at the Detroit auto show, Volkswagen's Passat BlueMotion Concept offers never-before technology in the Yank/Canuck family sedan segment: a four-pot motor with cylinder deactivation. Based on the EA211 1.4L turbo motor we sampled last year in the Euro-market Audi A3 sedan, the Passat BlueMotion Concept's engine is capable of shutting down the middle two cylinders during cruise, and features the Jetta Hybrid's gearbox, a twin-clutch unit capable of decoupling from the engine during off-throttle coasting. In the Passat's application, the 1.4 puts out 150 hp and 184 lb-ft of torque; VW suggests its highway fuel economy will stand at 42 mpg.
