Lamborghini Aventador Roadster sold out for the next year

It seems that the newly launched Lamborghini Aventador LP700-4 Roadster is already sold out until the middle of 2014. That North American East Coast outing comes just a few months after Lamborghini revealed its open-topped Aventador at the Los Angeles Auto Show in November with the same 6.5 litre V12 engine as its tin-topped sibling and a 0-62mph of a scant 3.0 seconds. At a UK price expected to be just the right side of £300k you might think, especially in these financially constrained times, Lamborghini might struggle to find buyers for its ultimate toupee wrecker.

Video: BMW M1 Hommage

BMW took the wraps off its latest concept car at the Concorso d'Eleganza in Villa d'Este this past weekend. Called the M1 Hommage, the concept is exactly what it says on the tin: pay homage to the iconic M1 designed by Giorgio Giugiaro, which celebrates its 30th birthday this year. The design of the M1 Hommage concept is a thoroughly modern interpretation of the original - compete with a louvered rear window - but it has grown in size over its thirty year old forebear.

Ownership costs of traditional versus alternative fuel vehicles

As gas prices remain high, and an increasing number of automakers roll out plug-in hybrid cars and full-electric vehicles, it's becoming easier to be tantalized with the idea of driving right past the gas station and simply "plugging in." The debate ensues when it comes to cost: These alternative fuel vehicles mean a larger outlay of cash at the onset, but the long-term fuel savings could make the purchase worthwhile. To help straighten out this numbers game, we use the Department of Energy's Vehicle Cost Calculator to compare alternative fuel vehicles with their gasoline-only counterparts. For each scenario, we assumed that our hypothetical owner was able to get the full $7,500 federal tax credit and a $2,500 state tax credit, such as is available in California.
