Daimler Chrysler is set to introduce an automotive first: integration of a lithium-ion battery into a passenger car. Planned for production in the 2009 BlueHYBRID, the lithium-ion technology is possible thanks to 25 patents now held by Daimler. Lithium-ion is more efficient and smaller than current nickel-metal batteries found into today’s hybrids, and require a climate control system for a long service life and max performance. The BlueHYBRID will be the most economical luxury sedan spewing out just 190g/km of CO2, and will achieve roughly 50km per gallon of gas. Far from the VW Diesel Hybrid we saw earlier this week, but a step in the right direction.
