The Rimac Concept S is a lighter, more powerful, and track-focused iteration of the Concept One. It can accelerate from 0-100 km/h in 2.5 seconds and reach a top speed of 365 km/h. Modifications to use carbon fiber reduced the weight by 110 lbs. Aerodynamic additions like a front splitter, side skirts, and large rear wing generate more downforce than the Concept One. The interior features racing seats and harnesses with a driver-focused display and alcantara trim. Only two Rimac Concept S vehicles were produced.
