You probably remember Jaguar C-X75 Concept – a hyper car that first unveiled at the 2010 Paris Motor Show featuring an XJ220-inspired design and a jet-inspired gas turbine powetrain. And you remember that last year it was confirmed for production with a new hybrid powertrain. Now news emerge that it may never happen.

The new system, comprising a 1.6 liter petrol engine with a supercharger and a turbocharger as well as two electric motors, is now undergoing its first real world test in a prototype. This is the critical phase, because at this stage Jaguar will decide whether or not they can make the car.

The powertrain has successfully past initial phases on a test bed in a lab, but to put it in an actual car and send it out, that’s a whole different ball game. Jaguar admits they have no idea if it’s going to work. And they cannot sign it off for production until they fully make sure it does.

This hybrid system seems a bit too complicated, but it’s definitely worth the hassle. If they manage to make it, we will have a Jaguar hyper car with four-wheel drive, 0 to 60 time of under 3 seconds, top speed of over 200 mph, an electric range of nearly 40 miles, and CO2 emissions of under 100 g/km.

So… fingers crossed!
