The boost in power helps pull the McLaren to a 10.6 quarter-mile, one-tenth of a second faster than in the previous year model.

Fisker Karma S concept

Fisker Automotive revealed the newest addition to its lineup at NAIAS 2009, exactly a year after the independent carmaker unveiled its first concept vehicle, the Karma.

The design of the S is likely to make it to the showroom almost unchanged.
