Concept Car of the Week: Lancia Bertone Sibilo (1978)

The second half of the ‘70s saw automotive design fall into an era of uninspired and uninspiring economic cars finished with cheap plastic add-ons and stuffed with beige itchy fabrics.

McLaren upgrades MP4-12C for 2013

The McLaren MP4-12C supercar will get a bevy of updates for 2013, and current 12C owners will have access to most of them at no charge. First and most importantly on the list is a power increase, from 592 hp to 616 hp, a 24-horse bump through engine-remapping.

Mercedes GLA 45 AMG: OFFICIAL

Mercedes GLA 45 AMG: OFFICIAL After the arrival of the Mercedes A 45 AMG – and its swoopy coupe sibling CLA 45 AMG – it was always more than likely that Mercedes would launch a GLA 45 AMG, and we saw the first evidence of that with the debut of the Mercedes GLA 45 AMG Concept at the Los Angeles Auto Show in November. But now, Mercedes has the production version of the GLA 45 AMG ready to go and we get the first photos and details ahead of its debut at the Detroit Auto Show next month. Powered by the same 355bhp 2.0 litre turbo as the A 45 AMG and CLA 45 AMG, the GLA 45 AMG manages to get to 62mph in 4.8 seconds (0.2 slower than the A 45 and CLA 45) and manages official economy fo 37.6mpg and 175g/km (but not in the real world).
