Hyundai ix35 Hydrogen FCEV for £300 a month and free fuel – but only in the U.S.

Hyundai Tucson Hydrogen FCEV (pictured) for £300 a month and free fuel – but only in the U.S. It’s very early days for cars powered by hydrogen fuel cells, not least because there’s very little in the way of a refuelling infrastructure in place. But car makers are starting to push FCEVs in a bigger way as production costs fall and performance increases, and Hyundai are at the forefront of this move with the hydrogen-powered ix35 and its US equivalent the Hyundai Tucson.

Hybrid owners sue Ford over Fusion, C-Max mpg claims

Pennsylvania car owners are suing Ford Motor Co., claiming that the 2013 Fusion hybrid and C-Max hybrid are not delivering on promised fuel-efficiency figures, according to a report from Bloomberg. Both hybrid models are advertised to return 47 mpg, but the owners say that number is inflated to seem more competitive among other midsize sedans, according to their court filing. The complaint says car owners who have submitted estimates to a fuel-economy tracking website averaged 38.5 mpg, a 10-mpg difference that can cost an additional $1,800 in fuel costs over five years, Bloomberg reports.

Lamborghini Aventador LP700-4 Roadster arrives next week

The Roadster version of Lamborghini’s LP700-4 Aventador will be revealed in Miami next week and debut at the Los Angeles Motor Show. The Lamborghini Aventador – successor to the Murcielago – was revealed by Lamborghini at the start of 2011 before getting a public debut at Geneva 2011, since when we’ve been anticipating the arrival of its Roadster sibling and even had confirmation of the Aventador Roadster from the EPA in the US. But the wait for the Aventador Roadster is now just about over with the news that Lamborghini will be debuting their open-topped Aventador at the Los Angeles Motor Show later this month.
