Quant e-Sportlimousine Unveiled with Staggering Performance Claims


Cutting-edge EV boasts a 236 mph top speed, clocks 0-62 mph in 2.8 seconds and has a 372-mile range.

Liechtenstein-based energy company nanoFLOWCELL AG revealed its Quant e-Sportlimousine this week at Geneva, presenting a state-of-the-art battery pack wrapped inside stunning sheetmetal. First shown in 2010, the latest concept – codeveloped with Koenigsegg and Bosch – is an electric sedan powered by four separate motors that combine to produce 920 horsepower. By today's standards, that's relatively conventional, but the rechargable energy storage system that powers the motors is far from it.

Dubbed a “flow battery,” the system mimics a standard battery, but uses tanks of negatively and positively charged electrolyte solutions that are circulated through a central cell stack. A membrane separates the solutions, while allowing for the electrical charge to pass through in order to produce power for the drivetrain. Company founder Nunzio La Vecchia claims the nanoFLOWCELL has five times greater performance-to-weight ratio than a lithium-ion battery, meaning the driving range would be five times that of a lithium-ion battery of the same weight. With a driving range of 372 miles, and storage capacity of 120 kWh, charging is done by replacing the electrolyte solutions.

Predicted performance is a 0-62 mph time of 2.8 seconds and a top speed of 236 mph. None of these figures have been proven outside of a laboratory as yet, but the company insists this is only a matter of time. As for the design, the Quant comes dressed in Crystal Lake Blue paint and sports aerodynamic styling, a sloping double bubble roof, copper accents, gullwing doors and 22-inch alloys. Four working prototypes will soon be built and after some real-world testing. A small production run of cars is planned.
