Chris Harris drives the Porsche 919 Hybrid

And yet the internal combustion engine in this thing is just 2.0 litres and configured as a V4. It is heavily turbocharged to produce about 500bhp and it really is physically tiny – buried against the rear bulkhead. The front axle is the single most impressive example of packaging I’ve ever seen in any vehicle. A single spring and damper sit horizontally ahead of a single electric motor that drives the front axle.

Due to a quirk of the WEC regulations, it has to run through a mechanical locking differential, rather scotching some mouth-watering torque-vectoring potential. The motor can produce up to 500bhp too. And it’s tiny – the size of a rolled-up sleeping bag. If one single component has changed my opinion of a potential electric future, it is that motor. To see its size, then hear the specification, and then eventually its effect, is quite something.

The front and rear axles are not connected, so the driver has separate traction controls for each, and the front axle disconnects completely above 240kph. Aragon is a high-speed circuit where the 919 has been tested extensively.
