It's only been a few days since GM's board of directors officially approved the Chevrolet Volt for production, but product czar Bob Lutz managed to grab some seat time in a prototype for the plug-in hybrid.
Writing on his FastLane blog, Lutz says the prototype - which essentially sticks the Volt's E-Flex powertrain beneath the body of an older Malibu - makes use of a sixteen kilowatt-hour lithium ion pack.; Although Volt prototypes have been running around GM's test sites since the end of 2007, they've only used the lithium-ion pack for the last few weeks.
Although he notes there's plenty of calibration yet to do before it hits the road, Lutz seems rather impressed with the electric-powered acceleration of the "Voltibu," noting it silently delivers plenty of torque at launch.
That said, he does take the opportunity to caution that this is still a prototype.; The lithium-ion batteries still need plenty of real-world testing, and Lutz hints that engineers haven't yet settled on a specific battery design or supplier.
