The Quant is back. Swedish supercar manufacturer Koenigsegg partnered with German firm NLV Solar AG on the Quant by Koenigsegg, shown at the Geneva Motor Show in 2009. It was a styling buck of a four-passenger sport sedan that used a brand new, proprietary propulsion system invented by NLV called Flow Accumulator Energy Storage (FAES). Intensely complex, it was said to be good for 512 horsepower and 527 pound-feet of torque, with a 300-mile range and a charge time of 15-20 minutes. The company wanted to have prototypes running in a year; obviously, that didn't happen.

NLV returned to the 2010 Geneva show, without Koenigsegg, with a Quant sedan powered by four 150-kilowatt electric motors, built on a carbon fiber chassis and having a body covered with a thin solar film making use of NLV's solar expertise. It planned to have a production-certified car ready by 2012; obviously, that didn't happen either.

This year the Quant returns to Geneva but under the auspices of a company called nanoFLOWCell, lead by the same Nunzio La Vecchia of NLV Solar. Nothing is being said about the car at the moment except that it will be longer than 17 feet, have four seats and be "the first car equipped with nanoFLOWCELL drive," which we will assume uses flow-cell battery technology.

According to Wikipedia, "The fundamental difference between conventional batteries and flow cells is that energy is stored as the electrode material in conventional batteries but as the electrolyte in flow cells." Among its benefits are a flexible layout and quick charging, but it's still a new and rather complex technology. If you're better with visual demonstrations, we've included a video below on one kind of flow-cell battery, the vanadium redox type, that explains it, along with a short press release. We'll be on the lookout for the latest Quant in Geneva.
