March 6, 2009 Swedish supercar manufacturer Koenigsegg, in conjunction with NLV Solar of Switzerland, is showing its full scale four-seater NLV Quant at the 2009 Geneva Salon. Producing 512hp with maximum torque of 715Nm, the Quant runs 0–100 km/h in 5.2 seconds and hits a top speed of 275 km/h. The all-electric car is powered through a combination of what it has dubbed a Flow Accumulator Energy Storage (FAES), which charges to full capacity in 20 minutes, and solar energy supplied via a thin layer photovoltaic coating over the car. The combined solar/FAES offer a claimed range in excess of 500km.
The thin layer solar technology and the proprietary FAES system enable the design of a fully electrical vehicle, rather than relying on more commonplace hybrid solutions. This also simplifies the drive train layout and packaging, as only one propulsion system is needed.
Koenigsegg says that the Quant will be able to cover long distances without a charge due to a combination of a low frontal surface area of around 2 m2, a drag coefficient of around CD 0.27 and the efficiency of the FAES and solar systems.
The ingenious design provides a unique blend of supercar looks and the space of a traditional luxury sedan. The car will carry four large adults in comfort and also feature a spacious boot at the rear.
The gull-wing doors on the Quant allow for an easy and more ergonomic access to both the front and rear passenger seats than in conventional cars. The unique split side-lite feature allows passenger to open and close the front and rear side windows separately.
The NLV Quant is a rear-wheel drive, with four-wheel regenerative braking (no details yet on how the front captures energy), ABS and ESP. It is powered by two 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, simplifying the lay-out and giving constant and controlled power proportioning to the rear wheels, in both drive and coast mode.
A projected curb weight of 1780 kg is achieved by a combination of the two-motor installation which weighs in at 140 kg and a carbon-fiber monotube backbone chassis, construction, which houses the FAES system. The FAES weighs around 450 kg and Koenigsegg advises that it contains no hazardous material or heavy metals.
In addition to the Quant, Koenigsegg will introduce a new touch screen infotainment system, a fast ATM paddle gear shift system and an electronic differential at the Geneva Auto Salon this year.
The touch screen Infotainment system features are:
The ATM Paddelshift system features a new gearbox design, which has been developed for the CCX. The gearbox is engineered to take up to 1100 nm of torque and due to its transversal layout, it is about 30 cm shorter then the manual transaxle gearbox it replaces, which improves weight distribution, says Koenigsegg. They go on to say that the gearbox features a synchronization system that allows shift times of 30 milliseconds - a great improvement, compared to existing synchromesh system. Basically it is as fast as a dual clutch transmission, but reduced in size and weight – two important factors in a Supercar, says Koenigsegg.
The gearbox also includes an electronic differential control. Koenigsegg says that the E-diff, makes the car easier to drive on the limit of performance, and thereby enhances the experience to most drivers. The gearbox is controlled with ergonomic paddles mounted on the steering wheel. Koenigsegg believes this to be the most optimal solution, as the paddles follow the steering wheel movements at all times.
We see the NLV Quant providing a benchmark for super cars into the future. It combines speed, comfort and enjoyment with environmental integrity. Given the vulnerability and price volatility of oil-based automotive fuels, having an all-electric power plant makes good sense. This new car allows for the design and performance from a supercar manufacturer Koenigsegg, to be featured with the latest developments in the thin layer photovoltaic technology provided by NLV Solar.
