Obvio, a Brazillian car company that has been manufacturing light-weight, high-efficiency 'tribrids' (natural gas, gasoline, and ethanol burners) has just partnered with Lotus to design their next round of vehicles. This is extremely good news because Lotus has a lot of experience designing light-weight attractive cars. Obvio, on the other hand, had some experience of it's own, designing extremely ugly light-weight cars.  Best of luck to the new Obvios there's a good chance they'll be for sale in a nearby metropolitan area in the next year.
