Koenigsegg Quant Concept

At the 2009 Geneva Motor Show Koenigsegg has presented the full-scale model of its Quant Concept, a full electric four-door coupé developed in partnership with NLV Solar, which provided the innovative thin-flm photovoltaic coating that covers the body. The goal is to reach a limited series production.

Koenigsegg Quant ConceptThe Quant Concept was developed by Swedish supercar manufacturer Koenigsegg in partnership with NLV Solar AG, a pioneer in photovoltaics and accumulator technology.

A full-scale model of this four-seater solar electric car was unveiled at the 2009 Geneva Motor Show, with the two companies currently working on running prototypes to scale up for series production.

The Quant is a battery-powered electric vehicle that can be re-charged to full capacity in just 20 minutes, thanks to the FAES (Flow Accumulator Energy Storage) system, with a range of 500 kilometres.

Koenigsegg Quant ConceptAmong the technical highlights are the carbon chassis with aluminium/carbon body panels and the innovative, invisible thin-flm photovoltaic coating that covers the body of the car which offers an additional power supply.

This system also contributes to the design of a fully electrical powertrain, which simplifes the drivetrain layout and
packaging, as only one propulsion system is needed.

The total output is 512 hp and the maximum torque is 715 Nm; which allows the Quant to deliver 0-100 km/h in 5.2 seconds and reach a top speed of 275 km/h.


Given the size of the NLV Quant, it has an unusually low frontal surface of around 2 square meters. This, combined with a drag coeffcient of around CD 0.27 and the efficiency of the FAES, will increase the car’s range.

The design team includes Christian von Koenigsegg, Nunzio La Vecchia (Project and Design Leader), Joachim Nordwall (Designer), Efraim Tangen (Modelling/Surfacing/Designwork), Victor Rosenvinge, Ketil Humlekjaer, Remi Andersen (Physical Modelling).

Koenigsegg Quant ConceptThe design provides a unique blend of supercar looks and the space of a traditional luxury sedan. The car will carry four adults in comfort and also feature a spacious luggage compartment at the rear.

The gull-wing doors are a unique feature for a production four-seater; in addition to represent a stylish feature, they also make entry to the car more ergonomic, thanks to the lack of B-pillars, thus providing a easy access to both the front and rear passenger seats.

The unique split side-lite feature 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.

Technical features

Koenigsegg Quant Concept Interior RenderingThe NLV Quant has a 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 Quant to deliver 0–100 km/h in 5.2 seconds and hit a top speed of 275 km/h.

Koenigsegg Quant ConceptAnother reason for the car’s low weight is the utilisation of a carbon-fibre monotube backbone chassis, construction, which houses the FAES system safely inside the centreline of the car at the lowest possible position, bringing down the centre of gravity and central mass point. The FAES only weigh around 450 kg and contain no hazardous material or heavy metals.

The project

The project was born when NLV Solar AG commissioned the environmentally aware Swedish supercar manufacturer Koenigsegg to develop and design a “car of the future”, incorporating NLV Solar’s groundbreaking, proprietary technology in the felds of photovoltaics and accumulators.

In 2008, the two companies signed a co-operation agreement to create a test vehicle for a unique propulsion system which makes optimum use of
the solar technologies developed by NLV Solar AG, allied with an innovative accumulator unit.
