The Aluminum karma

Car makers are all decking up their cars for the 2010 Geneva Auto Show. Are you ready? Looks matter. Do they? At least for cars, the answer would be a definite ‘Yes’. That is why Fisker has taken its Karma to the beauty parlour. Do you believe that? Is it just the looks? No. As far as Fisker is concerned, it is not the looks. Yes, you got it right. It’s the performance.


The Fisker is changing the skin of its Karma. The car wants to shed off some pounds. Yes, the beauty will look prettier. Not just that. Fisker is more bothered about the efficiency. The car is getting all set to show off its aluminum muscles. Yes, the lightweight, super-strong Karma will be walking the ramp at the Geneva Auto Show next month. Surprised? We were too. A car with an aluminum space frame will be displayed at the Geneva Auto Show.

The frame will be very strong, one of the strongest in the car industry. The torsional and bending rigidity too will beat that of other top sports cars. Let’s just wait till next month for the real picture. Aluminum will be giving the Karma the ease to move around quickly. The initial battery charge is believed to allow the car to run a mighty distance of 50 miles.

Would you like to see a picture of the Karma? No, Fisker will not show it. We will not even get to know the car’s weight. However, there’s something I can still tell you. The car uses 5000 and 6000 series high-strength aluminum alloys. It is built around a powertrain and drive system that includes a 2 Litre turbocharged GM Ecotec gas engine or generator up front, a lithium-ion battery pack down the center and a 403-horsepower, two-motor electric drive assembly in the rear. A structural tunnel down the center houses the battery pack and works as a torque tube connecting the front and rear frame sections. The whole thing is held together by 79 meters of precision welds and 1,058 self-piercing rivets. Isn’t this too much of news for the moment?

The frame had been designed keeping in mind the initial four-door sedan Karma. I just heard the rumour that Fisker would be coming up with a coupe and a convertible. No word from Fisker has come directly though. It also looks like the car will be using the same engineering and assembly parameters for the frames of the "Project Nina" family of smaller plug-in electrics. Isn’t that great news?

Now, will the Fisker Karma steal the show at the 2010 Geneva Auto Show? Will the lightweight aluminum muscles attract the right crowd? Well, hope we get just a little more news before the month end. I’m just too desperate to know more. You too? We will hopefully get some news very soon.
