Porsche plans to market a new lithium-ion starter battery for threedifferent 2010 model year cars. The battery weighs under sixkilograms, roughly ten kilos lighter than a normal lead battery.
Users of the 18Ah battery should notice no difference in performancewhen compared to the 60Ah Lead battery. The reason for this is thatlead battery users normally get the benefit of just 30% of the batteryat any given time, versus the 100% available power of the Li-ionversion.
Purchasers of the 911 GT3, 911 GT 3 RS, and the Boxster Spyder willbe able to get the lightweight battery as an option. German pricingfor the battery is an astonishingly high €1,904, including VAT.
As if that is not bad enough, previous purchasers of those threemodels can retrofit the battery for €2,499, beginning in February.
