Geneva: Quant e-Sportlimousine shows promising tech with a confusing backstory [w/video]

Quant Nanoflowcell e-Sportlimousine

The Quant e-Sportlimousine that you see here is just the kind of fascinating concept car that the Geneva Motor Show is known for offering up. The product of an energy company called nanoFLOWCELL AG based in Liechtenstein – with help at various points along the way from Koenigsegg and Bosch – the Quant promises a very advanced battery pack to power the electric drivetrain inside of this unmissable bodywork.

Details from the company website regarding the e-Sportslimousine are sparse and indecipherable in equal part, but the basics are nevertheless intriguing. The car is powered by a “flow battery” – specifically the nanoFlOWCELL from the eponymous parent company – which uses tanks of negatively and positively charged electrolyte solutions, pumped into and through a central cell stack. We’ve embedded a video after the jump to explain the processes behind the flow battery in greater detail, but the long and short of it is a system that is said to produce a nominal voltage of 600 volts, and a nominal current of 50 amps. Fed to four, three-phase induction motors, that juice nets a peak power output of 680 kW (912 horsepower) to all four wheels, with an “operating power” of 480 kW (643 hp).

Predicted performance is just 2.8 seconds to go from 0 to 100 km/h, with a top speed approaching 236 mph.

Predicted performance from the e-Sportslimousine concept is impressive in turn, with the company calling out sprint of just 2.8 seconds from 0-100 km/h (0 to 62 miles per hour), with a top speed approaching 380 km/h (236 mph). All that, and the range is said to be between about 400 to 600 km (250 to 370 miles) between charges. The company makes note that all of these figures have been simulated in a laboratory, so we wouldn’t recommend selling off your Model S just yet. NanoFLOWCELL does say that the vehicle “is neither a show car, nor a concept car” and has been “designed from the ground up to meet all homologation requirements.”

As for the rest of the car, it’s clear by the name that Quant would like onlookers to be impressed by the roomy seating accommodation made for four passengers, with what appears to be some high-zoot trimming. Acres of bent-wood trim can be seen, along with yard after yard of leather and Alcantara, and enough LEDs to make an Audi blush. Have a closer look for your self in our galleries, or dip into the slightly sketchy press materials we’ve assembled and nanoFLOWCELL press release, below.

Highlight at the Geneva Motor Show 2014: The world premiere of the QUANT e-Sportlimousine with nanoFLOWCELL® powertrain concept

“A vision becomes reality.” With these words, Nunzio La Vecchia presented the new QUANT e-Sportlimousine during the press day of the 2014 Geneva Motor Show. The world premiere of the first automobile with a nanoFLOWCELL® powertrain aroused great international media interest. This highly anticipated, revolutionary powertrain technology and energy-storage system can give new impetus to the field of electric mobility.

“The QUANT e-Sportlimousine is a research vehicle for road testing innovative energy storage systems, focusing especially on development and improvements in flow cell battery technology,” according to Nunzio La Vecchia, Technical Director of nanoFLOWCELL AG.

“The QUANT e-Sportlimousine is neither a show car, nor a concept car. It is the first automobile to be fitted with the nanoFLOWCELL® that is also designed from the ground up to meet all homologation requirements,” La Vecchia explains the direction of the intensive research and development work undertaken to produce the first prototype during the last few years.

How the nanoFLOWCELL® works
Flow cells combine aspects of electrochemical accumulator cells with those of fuel cells. Liquid electrolytes are kept in two tanks and circulated through the cell. At the heart of the system, a membrane separates the two electrolytic solutions, but allows electrical charge to pass through and thereby produce power for the drive train.

Advantages of the nanoFLOWCELL®
“The advantages of the nanoFLOWCELL® lie in its high charge density, high performance density, and its light weight compared to conventional energy storage systems. Furthermore, it contains no harmful substances, no moving parts, and it is very efficient,” explains Nunzio La Vecchia.

The nanoFLOWCELL® was conceived and is under active development at the nanoFLOWCELL DigiLab simulation lab at nanoFLOWCELL AG in Zurich, Switzerland. The results are very promising: At a nominal voltage of 600 V and 50 A nominal current the system is achieving an impressive continuous output of 30 kW. The nanoFLOWCELL® has a 5-times greater performance-by-weight than current lithium-ion technologies that power most of today’s electrical vehicles, meaning its driving range is 5-times greater than a conventional unit of the same weight.

The new QUANT e-Sportlimousine
Elegant, sporty and with an extraordinary design that underscores the special character of this car as the platform for a revolutionary new powertrain technology – this is the QUANT e-Sportlimousine in its world premiere at the 2014 Geneva Motor Show. With its length of more than 5.25 metres and a width of more than 2.2 metres and a height of 1.35 metres, the QUANT e-Sportlimousine makes a bold statement in terms of its dimensions and proportions.

“It was important to us that our four-seater QUANT e-Sportlimousine would be a very sporty car despite its size and unusual dimensions,” Nunzio La Vecchia is thrilled by the very positive public reactions at the car’s premiere in Geneva. Two unusually long gull-wing doors, large 1.7 metre wide side windows, extremely curved front and rear windscreen, no b-pillar, 22 inch tyres, and a short front bonnet are all part of the impressive optics of the new QUANT e-Sportlimousine.

The interior stands out with some unusual highlights: The two rows of seats, one behind the other in jet-cockpit style, accentuate the carbon fibre monocoque construction. The prototype presented in Geneva also won a lot of fans for its paint colour, “chrystal lake blue” developed exclusively for this vehicle, which reflects the character of the powertrain. The blue represents water; copper highlights, the flowing of electricity.

Another distinctive feature of the new QUANT e-Sportlimousine are its wooden operating controls. The new sensorFLOW® technology provides a visual highlight never seen before in automobile control elements. At first glance, you only seen the natural, smooth ash wood surfaces. Once the QUANT e-Sportlimousine is activated, the control elements become visible through the natural wood. “The wood surfaces are so thin that a light touch of the finger on the sensorFLOW® icons triggers the appropriate action,” enthuses development lead Nunzio La Vecchia, “This innovation allows us use a sustainable material like wood to give you a direct connection to the digital control systems.”

The interior also features modern display technology more than 1.25 metres wide and 16 centimetres tall, the front display gives this car that widescreen cinema feeling. The QUANT e-Sportlimousine’s complete infotainment system is implemented in an Android-based system. The new QUANTmobile App allows the driver to access the QUANT e-Sportlimousine’s climate and infotainment controls from outside the vehicle. Driving statistics and navigation functions are also accessible from a smartphone.

Upcoming events
The next public presentation of the QUANT e-Sportlimousine will be April 17 to 20 at the nanoFLOWCELL AG stand at Top Marques Monaco 2014.
