How does a Jaguar engine sound at 10,000rpm? It sounds like this.
With any normal Jag, it would be the sound of a mechanical catastrophe. What you have here, instead, is a hard-edged howl of performance that takes you straight back to the four-pot turbo F1 cars of the 1980s.
The engine of the C-X75 hypercar is safe to this dizzying figure. Top Gear heard, and saw, the prototype engine safely doing this today, its turbo glowing red-hot (below). It makes 500bhp from 1.6 litres and has a supercharger and a turbo.
