KOENIGSEGG QUANT
Swedish supercar marquee Koenigsegg and NLV Solar AG, a pioneer in photovoltaic and accumulator technology, have joined forces to create the Koenigsegg Quant. The brainchild of this marriage of power and energy is a four-seater solar electric car. A full-scale model is to be unveiled at the 2009 Geneva Salon, with the two companies currently working on running prototypes to scale up for series production.
The NLV Koenigsegg Quant is rear-wheel drive, with four-wheel brake regeneration, ABS and ESP. It is powered by two electrical AC induction electric motors with variable frequency drive and in-line planetary step down drive, one for each rear wheel. The twin-motor design eliminates the need for bevel gears or a differential, further simplifying the lay-out and giving constant and controlled power proportioning to the rear wheels, in both drive and coast mode.
The projected curb weight of 1780 kg is very light considering that it is a battery-powered, four-seater, luxury performance car. This is partly due to the two-motor installation which weighs in at only 140 kg – a remarkable achievement considering the power output of 512 hp and maximum torque of 715 Nm which allows the Koenigsegg Quant to deliver 0–100 km/h in 5.2 seconds and hit a top speed of 275 km/h. Another reason for the car’s low weight is the utilization of a carbon-fiber monotube backbone chassis, construction, which houses the FAES system safely inside the centerline of the car at the lowest possible position, bringing down the center of gravity and central mass point. The FAES only weigh around 450 kg and contain no hazardous material or heavy metals.
