A Jaguar XE prototype was recently spied during testing on the Nurburgring Nordschleife race track in Germany. As you're probably expecting, the Jaguar XE test car is completely covered in camouflage. So, we can't tell you much about its design. However, we managed to learn that Jaguar is going to sell the XE with a 3.0-liter V6 engine and with a 5.0-liter V8 powertrain. According to unofficial specs, the supercharged V8 version of the XE Jag is going to deliver just over 540 hp.
