Rimac is a world leader in high-performance electrification and Porsche knows a thing or two about it too. Apparently I’m here to drive the Chiron Super Sport and revel in the staggering numbers (it eats 1000 liters of air per second at full revs and acceleration), but can we also talk about electrification?
One thing that strikes me about this Chiron is that despite two of its four turbochargers being revved low to improve response, the W16 engine still makes almost 200bhp per litre, so some lag is inevitable. . It churns and builds the way an EV, well, doesn’t.
“The acceleration [of EVs] it’s huge, and they can beat all the numbers from zero to whatever,” Wallace notes, but they struggled to reach or maintain a really high top speed.
“To hit 300 mph in any car, you’re basically wide open for a few seconds,” he explains. “During that event in a combustion car, you’re going to 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] and then the inverter is converting that into the power that the motors need, the inverter is getting hot. You can draw the power for a certain period of time, but then to save yourself [from the heat], you gain a power reduction. So you don’t have it long enough to hit 300mph, although I’m sure it will happen eventually.”
