Inhabitat has a post on an unusual carbon free racing car from Mercedes Benz - Mercedes’ Futuristic Formula Zero Sail Racer.

Recently Mercedes Benz revealed images of its stunning Formula Zero Racer, a futuristic foray into the next generation of racing. Incorporating elements from luge, yacht, and Formula One vehicles, the zero-emissions racer is propelled by a wind-catching sail in addition to electric motors that are powered by renewable resources. The concept is a tribute to a future where cars will win races based not just upon their speed, but on how energy efficient they are.

EcoGeek reports that Mercedes-Benz aims to eliminate petrol powered vehicles from its product lines by 2015 - well ahead of time. Presumably diesels will go eventually too.

In less than 7 years, Mercedes-Benz plans to ditch petroleum-powered vehicles from its lineup. Focusing on electric, fuel cell, and biofuels, the company is revving up research in alternative fuel sources and efficiency.

The German car company has a few new powertrains in the line-up that European journalists have had the opportunity to test out in their facility in Spain. One vehicle includes the F700, powered by a DiesOtto engine that combines HCCI and spark ignition to get nearly the same efficiency as diesel, but minus the expensive after-treatment systems. The engine can run on biofuels, and we may have a purchasable vehicle by 2010 – a year that seems to be popular for the debut of a lot of new alternative fuel car models, making ’08 and ’09 simply thumb-twiddling years for consumers. I don’t know, maybe car makers just like the roundness of “2010.” The company’s next big step will be to launch a Smart electric car which is fuel and emission-free.

Anyway, Mercedes is looking into electric vehicles, both battery powered and fuel cell powered. Not only are models in development, but we’ve also seen the company making steps towards their zero petroleum goal right now, from better cabs in London to Li-Ion battery improvements. The company also has about 100 Smart electric cars undergoing testing in London, with that favorite 2010 year as the projected market release date. Mercedes is making serious investments, already putting nearly $4 million into the pot of their long-term Sustainable Mobility plan, with another over $14 billion going in before 2014.
