A video has surfaced on YouTube showing the new Jaguar XE SV Project 8 laying down some numbers on a dyno. The readouts tell us the actual power of the engine.
What the manufacturer says in regards to engine power and what an engine actually produces is often quite different. Sometimes car companies under-quote their outputs and sometimes an engine doesn’t end up producing as much as the carmaker claims.
Harry’s Garage YouTube channel recently put the new XE SV Project 8 to the test. This is Jaguar’s latest fire-breathing model which currently holds the Nurburgring lap record for a production sedan, clocking a blistering lap in 7:21.23.
In the engine compartment is a 5.0-litre supercharged V8 that produces 441kW (592hp/600PS) and 700Nm, according to Jaguar. This is the most powerful production Jaguar ever made. On the dyno, it looks like it’s actually more powerful than what Jaguar says.
Harry’s example laid down an impressive 601hp (448kW) and 686Nm at the engine. However, on the day, the Jag peaked at an impressive 620hp (463kW) at the specific temperatures of the day. The advanced dyno used was also able to calculate the power at the wheels, showing 485hp (362kW), resulting in a drivetrain drag of 135hp.
As we all know, the power isn’t the only awesome part of the XE SV Project 8. It showcases some crazy aero features, racing-like bucket seats, racing brakes and suspension, and all wrapped up in an elegant Jaguar design. The fact that it actually produces more power makes it even more awesome. Check out the dyno video below to see how it goes and sounds.
