We saw this on the rolling road. And heard it, to the extent that we had to put our fingers in our ears. Standing close to a car on a rolling road that is spinning at 207mph is a bracing experience, as you hear – and then see through the print-out – 641bhp pouring through the four wheels.

If you had bought an F-Type SVR then you’d have bought 567bhp and 516lb ft. Sounds impressive. But this Predator model has the 641bhp and also 687lb ft of torque. British company Viezu Technologies is responsible for unleashing all that power, and they do so virtually without raising a spanner.

Finding more power in modern engines means picking up the laptop not the socket set. Specifically, Viezu focused on the thousands of maps within the software, ensuring they focus on things like the supercharger maps and not the ones for the temperature control.

The change maybe 60 maps out of the thousands and even then any change only comes in at about 60% throttle. This means the car has the normal driveability of a standard car so you can potter about if you wish with no apparent clue as to what can happen if you put your foot down. Then you put your foot down.

If you’re going to do that then you need to be paying attention before you do it, not after. This is like a Lamborghini Aventador, it’s that aggressive, sudden and violent. It’s really, really quick in a way that needs your total commitment. And all the while the soundtrack is filling your mind, since the sort-of freeflowing exhaust hammers away at your eardrums like a monster trying to get into your brain.

Viezu has also added in a lot of bodywork upgrades, mostly in carbonfibre, and also some suspension changes, such as a lowered ride height and polybushing. On smooth roads that all works well but on rougher backroads there is a discrepancy between performance and the car’s ability to handle it.

We might pass on some of those upgrades, but that’s the joy of this, you can choose how much of a Predator you want. So, if you had about your person a used F-Type V8 R, then you’d need to find another £8k or so to gain the sort of performance that puts you well ahead of the more expensive SVR version. Now there’s a thought.
