We first saw the Rimac C_Two at the Geneva motor show, and now the Croatian manufacturer has given us an update on its development process. In a new post, Rimac details how its engineers have used a mixture of physical models and initial CFD simulation (computational fluid dynamics) to hone the aerodynamics of its new electric supercar.
Of course, pretty much every car you see on the road is designed using the same combination of complex simulation and wind-tunnel testing – but it’s still interesting to see how Rimac is developing the C_Two.
The blog posts states that the company is using a 7000-core supercomputer called BURA, at the University of Rijeka in Croatia, and the computer calculates the flow of air at 70 million divided sectors on the car.

After that, a full-scale model of the C_Two was made to test CFD parts, and analyse everything drag coefficient to cooling efficiency. Interestingly, Rimac says there was only 2.4% deviation between its simulated results and wind-tunnel ones.
Rimac will then take the C-Two to the track, where an even less sterile environment will confirm what it's already seen in simulations and wind-tunnel testing.

So what’re the specs?
At most motors shows, engine figures seem to become meaningless – and that’s probably thanks to cars like the Rimac C_Two. According to the EV maker, the C_Two’s four electric motors can develop a total of 1,887bhp and around 1,700lb ft of torque. Like we said, these numbers are almost meaningless now.

As for getting that power on the road? The C_Two uses a single-speed transmission to put power down from the front wheels, while teach rear wheel has its own dedicated two-speed gearbox. The result? A theoretical top speed of 258mph, and a 0-62mph dash time of just 1.97 seconds. If you need it - and it’s unlikely you will – the Rimac can also go from standing to 100mph in just 4.3 seconds. With those figures, the Rimac C_Two may end up being one of the fastest cars – as well as EVs – in the world.
However, the Rimac also has a eight cameras, a lidar, six radars, and twelve ultrasonic sensors stuffed into its 1950kg chassis. What’s that doing in a hypercar you ask? Well, it’s making the Rimac C_Two ready for Level 4 autonomy – not something you’d usually expect in a supercar.

As for how much it’ll cost and when it’ll be here, we don't know yet – but we’ll update this article when we find out.
