Geneva: Fisker shows off Space Frame of 2011 Karma
Nine months to go before its launch, no one from the media has ever driven a 2011 Karma. Its maker Fisker decided to reveal the space frame of this plug-in sports sedan during the Geneva Motor Show.
The space frame is designed to play a vital role in distributing the hybrid powertrain throughout the Fisker Karma. The frame holds the engine-generator under the hood of the car.
The lithium ion battery pack of the 2011 Karma is positioned at the spine of the car. This battery makes use of iron-phosphate cells manufactured by A123 Systems. The battery pack is located at the least vulnerable space if ever the driver meets a road mishap.
The 403 horsepower electric motor can be found just behind the rear seat a bit in front of the rear wheels.
The founder of the company noted that the focus of the design must be on torsional rigidity and adaptability to new styles of the car’s body foreseeing the coming of the 2012 Karma S which will have a retractable hardtop.
The space frame is very strong according to Henrik Fisker himself. He explains that the components are joined by about 260 feet of MIG welding spots and about 1,000 rivets. The car is also said to have great resistance to angled roads with about 33,000 N-m for every degree.
