Mercedes is augmenting its hybrid vehicle offerings with an S Class luxury car that will be a highlight of its 2009 line. The S Class 400 hybrid will use electric motors and a battery pack to augment its 3.5l, six-cylinder engine. That battery pack will be supplied by Johnson Controls-Saft, a joint agreement between the suppliers of automotive components and batteries, respectively. The battery supplier will also provide the control system that makes sure its lithium-ion batteries operate safely over a long lifetime. Initial performance specifications for the 400 claim mileage in excess of 40 mpg, a high level for a luxury vehicle.
