American carmaker Czinger has unveiled the 21C, its hybrid hypercar for 2021 that's made using 3D printing processes. Apart from claiming stellar on-road performance, the 3D-printing methods employed for the 21C ensure a much more efficient production process, with each part first tested and modeled on computers, and then constructed via 3D-printing. This means there's very little wasted material, making for an efficiently constructed car. The 21C is powered by a 2.88 liter twin-turbo V8, which supported by two electric motors develops a combined 1,250 bhp, enough to get it from standstill to its near 400 kmph top speed in just 29 seconds. In line with a sustainable production method, the car runs on methanol that's extracted for biomass, making the 21C's emissions carbon neutral.
