For years, automotive experts have speculated that if a company could come up with an economically viable alternative to the gasoline engine, they would launch us into the future. Enter the Quant e-sportlimousine.

Back in March, this car was shown off and was thought to be a fun prototype, however, the brand is now saying they plan on mass producing and selling the vehicle after it was recently approved for use on public roads in Germany.

The vehicle uses what the brand calls a “NanoFlowcell,” which is a flow cell power system that is powered by saltwater. The system was originally developed by NASA for use in space flights in the ’70s.

How fast and powerful is a vehicle that supposedly runs on saltwater? The Quant e-sportlimousine hits 60 mph in just 2.8 seconds and has the potential to pump out 912 HP, though the ones that are going to be put on the market will churn out 643 ponies.  Its top speed is 236 mph, with a driving range of 370 miles (these specs come from Quant).

Obviously, there are many who are still very skeptical of those specs given the claim that it runs on saltwater, but we shall see as the car goes into development.
