In order to meet the increasingly stringent demands of fuel efficiency regulations, Mazda is rolling out some new green technologies that will be featured in future cars.  Car and Driver's article is here.  A short summary: We like Mazda’s strategy for the simple reason that stuff like stop/start, energy regen, and diesel engines can be added without greatly affecting the fun-to-drive appeal of the company’s cars, nor will they add huge levels of cost.  Sounds good to me.  

Yes there are 100 different cars out there that can be considered "green."  This is evidence that fuel efficiency has passed way beyond fad stage.  See Yahoo!'s list here, where cars are ranked according to their green rating. 

Honda has a new concept to be shown at the 2010 Geneva International Motor Show.  The 3R-C3, not to be confused with this, is described as a "revolutionary three wheeled battery electric vehicle concept shows what a future minimal urban transport vehicle for one person might look like. The battery electric drivetrain is mounted low in the three wheeled chassis, therefore keeping the centre of gravity low and thus improving stability."  I think it looks like one of the motorcycles from Tron, which at the end of the day, is pretty cool.  It will be featured alongside the FCX Clarity.  See the press release here.  

Did you know that when electric cars become available to the public, that you will only own the car, and not the battery?  Read about it here.  What do you think about not owning your ENTIRE vehicle?
