Rimac is a world leader in high-performance electrification and Porsche knows that too. I’m here ostensibly to drive the Chiron Super Sport and revel in the astonishing numbers (it sucks 1000 liters of air per second at max revs and throttle), but can we also talk about electrification?

One thing that strikes me about this Chiron is that, although two of its four turbochargers are throttled at low revs to improve response, the W16 engine still produces close to 200 hp per litre, so some lag is unavoidable. It blows and builds the same way an EV, well, doesn’t.

“The acceleration [of EVs] is huge, and they can beat all numbers from zero to anything,” Wallace points out, but they struggle to reach or maintain a very high top speed.

“In order to hit 300 mph in any car, you’re basically open for seconds,” he explains. “During this event in a combustion car you will be putting a lot of energy into the water and the oil, but the cooling systems are such that you can stabilize that temperature.

“When you draw power from the battery [in an EV] then the inverter converts that into the power the motors need, the inverter gets hot. You can draw energy over a period of time but then, in order to save yourself [from the heat], you get a power reduction. So you don’t have it long enough to hit 300mph – although I’m sure eventually it will.
