Rimac is keeping the vital details of its second hypercar secret so far but apparently some of them are out.

Citing a source close to the manufacturer, Autocar reports that the new Rimac hypercar will come with a 120kWh battery pack. Previous reports suggested that the upcoming electric car will offer a longer range than the Concept One’s 210 miles, backing up the reported battery capacity.

The Croatian manufacturer will also make its new model capable of Level 4 autonomy, meaning that the codenamed ‘Concept Two’ will be able to drive itself completely and without the driver’s attention where legal, but with a driver still sitting behind the wheel.

Other sources claim that Rimac changed their targets for the new model when Tesla announced the new Roadster, which claims a 0-62mph in 1.9 seconds and will feature a 200kWh battery pack.

Rimac has already teased the new model ahead of its world premiere at the Geneva Motor Show. Compared to the Concept One, which was produced in just eight examples, plus two track-only Concept S versions, the new car will feature a roomier cabin and, more crucially, more power and better performance figures.

The Concept One was powered by four electric motors mounted on each wheel, producing a combined 1224hp and 1180lb-ft of torque. 0-62mph takes just 2.5 seconds.

Rimac is targeting a limited production run of 100 cars for its second hypercar, which will debut on March 6 at the Geneva Motor Show.
