A Rival for Tesla, the Concept One All Electric Sports Car from Rimac Automobili

The Concept One
Rimac all electric sports car is competition for Tesla

The Concept One All Electric Car from Rimac ( Solar Thermal Magazine)  – Rimac Automobili, as an automobile manufacturing company was established in 2009 in Zagreb, Croatia in it’s founder best friend’s  garage. The company’s primary objective was to build an electric supercar, starting, as Rimac put it, “with a blank sheet of paper”.

The story goes that when Rimac’s 1984 BMW E30 blew its internal combustion engine during one a race, he made it the company’s first test mule, fitting it with a 600 hp electric powertrain. This first electric car, called the “Green Monster”, set five Fédération Internationale de l’Automobile (FIA)-sanctioned acceleration records in April 2011.


What is it about electric cars?

It is true that even primitive (DC) electric motors can outperform any combustion engine in efficiency, response time, power band width, size, regenerative braking and torque.

The concept one powertrain is divided into four sub-systems, each consisting of one motor, inverter and reduction gearbox. Each of those systems drives one wheel, completely independent one from the other. Each wheel can independently accelerate or decelerate hundreds of times per second, helping to achieve the driver selectable handling.

The Concept One is a completely different car from the Green Monster prototype that launched Rimac Automotive. See if you think this car can give the Elone Musk Tesla line up a run for it’s money. Check this out.
