The Koenigsegg Quant which was displayed at the 2009 Geneva
Motor Show is the product of a collaboration between NLV
Solar AG, a company involved in photovoltaics and accumulator
technology, and Koenigsegg.
The Quant project was initiated when NLV Solar AG commissioned
the Swedish supercar manufacturer Koenigsegg to develop
and design a "car of the future", incorporating
NLV Solars groundbreaking, proprietary technology
in the field of photovoltaics and accumulators.
The advances in electric power generation and storage,
combined with the aerodynamic, futuristic Koenigsegg design
and engineering, will enable the NLV Quant to charge the
FAES (Flow Accumulator Energy Storage) to full capacity
in 20 minutes and give the vehicle a range of 500 kilometres.
The additional power input from the invisible, thin-film
photovoltaic coating that covers the body of the car,
further increases the potential range.
The NLV Quant concept 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 layout and giving constant and controlled power proportioning
to the rear wheels, in both drive and coast mode.
In total the two motors weigh just 140 kgs (308 lbs) but
produce 512 horsepower and 715 Nm of torque. This means
the Quant can hit 60 mph in 5.2 seconds and reach a top
speed of 170 mph (275 km/h).
The Quant is fitted with gull-wing doors which aside from
being a striking feature, also make entry to the car easier
due to the lack of B-pillars. They provide easy access
to both the front and rear passenger seats. The split
side windows allows all passenger to open and close the
front and rear side windows separately, despite the fact
that there is only one door per side.
Currently both Koenigsegg and NLV Solar AG are developing
further prototypes of the Quant in order to assess the
viability of a production version.
