Mercedes-Benz Plans on Building S-Class E-REV

Mercedes-Benz is looking to build an S-class plug-in hybrid (actually, from the description, it's an E-REV (Extended-Range Electric Vehicle)) that will achieve 81 mpg. More details are coming out according to CarandDriver.  Mercedes-Benz launched a hybrid S-Class in Japan last September.
 
The new S-class will mate a 3.0-liter V-6 gasoline engine-dirct injection and peizo injectors witha 60 hp electric motor. The electric range will be about 20 miles.

Mercedes-Benz Thomas Weber feels that the biggest issue with electric cars is the battery. From the expense, charging time, possible overheating, to just the extra weight. Thus, they are looking at the variants which will allow them to use smaller batter packs, but still keep the range and reduce the cost of the vehicle.
