Mazda diesel delayed again

If you've been waiting for a Mazda 6 diesel, prepare to wait a bit longer. After delaying the US launch until Spring 2014, Mazda now says it won't meet that target date either. Mazda says the engine meets current emissions standards using only a particulate filter, but the resulting blend of performance and fuel economy isn't up to snuff.

Aston Martin V12 Vantage Roadster: Official

Following the leak of Aston Martin V12 Vantage Roadster photos and an undisguised car in London we now get the official reveal of the V12 Vantage Roadster. The leak of photos we had of the Aston Martin V12 Vantage Roadster last week (assuming they were a leak rather than a Photoshop) managed to make the new soft top V12 Vantage look decidedly bland (not an easy thing to do with an Aston). But the photos of the V12 Vantage Roadster we had at the weekend were much more appealing; a white V12 Vantage Roadster obviously on an official photoshoot in appealing London locations.

Alfa Romeo 4C in action at the Goodwood Festival of Speed (video)

The Alfa Romeo 4C made its dynamic debut (pictured) at the 2013 Goodwood Festival of Speed The long awaited Alfa Romeo 4C finally made its debut in production spec at the Geneva Motor Show in March, and at the weekend the 4C made its dynamic debut at the Goodwood Festival of Speed. To make sure the 4C made as big an impact as possible at Goodwood, we’d expected Alfa to run up the hillclimb in the launch edition 4C, which gets plenty of extra goodies including a carbon fibre body kit and spoiler, but this 4C looked to be a standard model. But even though we’d like to have seen the launch edition with its extra carbon fibre goodies, the standard car gets exactly the same 1750cc 4-cylinder petrol engine with enough get up and go, 236bhp, to move the lightweight 4C (under 900kg) to 62mph in just 4.5 seconds.
