For a $80,000 model, the 2009 Firsker Karma hybrid sedan is expected to offer a lot of luxury options. Nothing spooky here, right? Well is time to become a bit more mysteriously: the company decided that there is no need for the car to be silent (?!), instead they have decided to fit the car with speakers inside and out to blast fake engine sounds!!!

According to Henrik Fisker, head of the company, by fake engine sounds it means real, gruff, user-selectable engine sounds. One will apparently sound ''like something between a Formula One car and a jet plane," which should certainly be enough to keep unwary pedestrians leaping for the sidewalk as you roar towards them.

And the logical explanation for this decision is...?
