If you want to achieve great things, you have to set bold goals and then do your best to meet them. Mercedes now has the first part of the equation down, lets hope they can deliver on the execution.

Their plan is to make their whole car lineup petroleum free in 7 years. To do that, they’re looking at battery electric cars, fuel cells, and more efficient combustion engines that can run on biofuels (lets hope that by then we have truly sustainable ethanol and biodiesel). “The company have already spent £2million on their new long-term Sustainable Mobility plan and are set to invest a further £7billion before 2014.” Of course, there’s a catch: A car that can run on biofuels can still run on fossil fuels, so without a good supply of sustainable biofuels, that’s probably how they’re going to be used. But still, a step in the right direction.

 I’m not too fond of the Hummer H3′s design but this concept looks pretty interesting. The car looks quite futuristic and reminds me of Halo’s Warthog.

To be dubbed Reventon, it’s based on the Murcielago LP640, and it’ll cost a breezy one-million euros. Only 20 are set to be constructed, and all have been already betrothed to high rollers who’ve reportedly ponied up more than $300,000 each as a deposit. Rumors had indicated the car was inspired by jet fighters, a prospect bourne out by the greenish dash cluster. It even has a gauge to track G forces, just in case you weren’t busy enough making that sweeping left hander off the back straight on track day.

Here are some artist impressions of the Reventon:
