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.

Following the unveiling of the striking S550 Coupe at the recent Geneva motor show, Mercedes-Benz has now taken the wraps off the even more powerful S-class two-door: The 2015 S63 AMG Coupe. It's set to make a public debut at the upcoming New York auto show. The plush, leather-lined four-seater, which will lock horns with the Bentley Continental GT when North American sales get underway later this year, runs a carryover twin-turbocharged 5.5-liter V8 engine from its predecessor, the CL63 AMG.

Toyota GT86 TRD Griffon makes its debut at Goodwood (video)

The Toyota GT86 TRD Griffon 9Pictured) made its debut at Goodwood this weekend We’re still waiting for Toyota to make a more powerful version of the GT86 (and Subaru the BRZ), but we are starting to get more focused versions. We’ve already seen the GT86 TRD – developed by Toyota Racing development – as a road car limited edition, and last month we learnt that Toyota were going to debut a track version – the GT86 TRD Griffon – and that it would arrive at Goodwood. Now the Griffon has arrived looking immensely purposeful with its wings and diffuser and carbon fibre for the roof, doors, bonnet and boot and some severe fettling of the oily stuff with upgraded brakes, new alloys, mechanical limited slip diff and stiffer suspension.
