The Cost Of Additional Porsche (Li-ion) Lightness: $132/lb.
Never one to shy away from expensive options, Porsche has announced that beginning in January 2010, a lithium-ion starter battery will be optional in the 911 GT3, GT 3 RS, and Boxster Spyder. Porsche is the first automaker to offer a li-ion SLI (starting, lighting ignition) battery, and given its cost, €1,904 (US$2,900), it may stay that way for a while. The new pack weighs 6 kg (13 lb), which is 10 kg or 22 (lb) lighter than a conventional 60 Ah lead battery. That works out to $132 per pound saved, based on European pricing. US pricing has not yet been announced. That sounds like a bargain compared to some of Porsche’s other pricing shenanigans. Ask the fellas in the paint booth to leave off the masking tape on a certain number of exterior and interior pieces to make them body colored, and they’ll ask you a mighty $13,545 for their (non)effort. Only a company that has the cojones to do that would to try to take over VW. I digress. More battery lightness after the jump:
