E85 makes inroads on cost and availability

Three years ago, we embarked on a Midwest road trip in search of what was then the Holy Grail of fuel: E85. Our findings weren't too positive--there were far more E85-compatible vehicles on the road in 2006 (5 million) than there were E85 pumps to fuel them (about 700 out of some 200,000 fuel stations nationwide). In addition, those burning the mix of 15 percent gasoline and 85 percent ethanol were paying a pretty penny for their earth-friendly ways, losing about 15 percent in fuel economy while often paying the same price as regular unleaded.

SEAT Leon FR 2.0 TDI 184 PS costs from £22,075

The SEAT Leon FR 2.0 TDI 184 PS (pictured) arrives in the UK from £22,075 The 2013 SEAT Leon arrived at the Paris Motor Show last year as the Spanish take in the VW Golf. And now the SEAT take on the Golf GTD is in the UK – the SEAT Leon FR 2.0 TDI 184 PS. With a dose of Spanish flair making the SEAT a more flamboyant, and appealing, car than the Golf, it comes with the same 181bhp 2.0 litre diesel as the GTD, offering 0-62mph in 7.5 seconds and 67.3mpg.

Lamborghini Murcielago LP650-4 Roadster

Lamborghini Murcielago LP650-4 Roadster Expected to sport the same 650bhp engine as the Reventon, this LP650-4 looks like it’s going to be one of the quickest open-topped cars there is, with a 0-60 time just over 3 seconds. Just like the Reventon, the LP650-4 looks likely to come in just one colour choice, in this case a matt grey (Grigio Telesta) with orange accents, and dark painted alloys. With the expected launch of the LP670-4 SV happening at Geneva in a couple of weeks, it is unlikely that Lamborghini will show this car, more likely saving it for later in the year for maximum impact.
