While we're clamoring for small, efficient transportation, Europe is already awash with micro cars, diesels, and hatchbacks. When Toyota designed and engineered the tiny iQ, it had to go smaller and greener than the competition, so the little four-seater is only about 1.5 feet longer than a Smart fortwo. AutoExpress is reporting that Toyota is prepared to take iQ to the next level of green, with a plug-in hybrid version of the micro mini. Plug-in technology would reportedly be shared with the next generation Prius, save for an engine that goes from 1.0L to a displacement of only 500 cc. Chargeable batteries will enable the iQ to travel 15 miles or more without a drop of CO2-spewing combustion, and the smaller engine would stay stingy when it does come to life. While the iQ is probably still a little too small for large scale US consumption, we're sure the vehicle would have quite the cult following if it could pull off fuel economy in the 100 mpg range. If gas decides to travel back north of the $4 mark, though, even a clown car would be acceptable Stateside.

Fisker Automotive is going to have its work cut out for it when it comes to meeting its self-imposed deadline of bring the Karma sedan to market by the fourth-quarter of 2009. To complicate matters even further, the automaker is now rumored to be working on three more plug-in hybrids. That would represent a truly serious undertaking for such a small automaker. To ease matters slightly, all four models would use the same basic underpinnings -- including the most important piece of all, the lithium ion battery and its assorted bits. Fisker has recruited Quantum Technologies, a company which has seen success building vehicles for the military, for help in creating the drivetrain for its electric vehicles. Reportedly on the drawing board are a coupe, a convertible and an SUV, all of which should go a long way towards meeting Fisker's goal of selling 15,000 vehicles a year by 2011.

The attention of the hybrid technology universe has been focused firmly on two vehicles: the Chevy Volt and the plug-in Prius. On the surface, these two vehicles are primed to be big-time competitors in the battle for mpg-conscious buyers. Not so, says the king of quote, Maximum Bob Lutz. According to Mr. Lutz, the two vehicles are very technologically different. Toyota also says that a plug-in Prius will be in production in 2009, a full year ahead of the Volt. Lutz hypothesizes that the Prius plug-ins will be available only to select fleets and not in large scale production, and the GM Vice Chairman says that the Volt will be available as part of a large test fleet in late 2009, as well.

We agree that the Volt and Prius are technologically different, but we're pretty sure the two vehicles will be competing for the same buyers. After all, Americans are calling for more fuel efficient vehicles and don't care if one's a plug-in parallel hybrid that runs on nickel-metal hydride batteries and the other is a series hybrid with lithium-ion batteries and a "range extender". They just care about whichever one can go further on a drop of fuel.
