The development of the Bugatti->ke16 killer from Britain has entered a critical stage that decides whether Jaguar’s newly developed hybrid system and the C-X75 project as a whole deserves the green light or no.

For the past three months, Jaguar has been testing the hybrid system on a test bed and is now confident enough to install it on a rolling chassis to create a working prototype. Now the anticipation meter is back to its highest point after months of silence.

When it was first revealed at the 2010 Paris Motor Show, the Jaguar C-X75->ke3681 featured two turbines that looked like rockets attached. Since Jaguar was gunning for the top-spot in performance, the rockets did make sense. But, they weren’t there to launch the car down the road like a Wile E. Coyote contraption; they were actually a pair of gas turbines to power the car once charge for the four wheel-mounted electric motors had expired.

What looked promising when Jaguar bragged about was later scrapped when the Leaping Jag announced the production of the hypercar in 2011.

The gas turbine system was replaced with a hybrid system that combined a 1.6-liter boosted engine that produced more than 500 horsepower and four insanely powerful electric motors powered by a highly sophisticated liquid- and air-cooled battery pack.

So far, the tests conducted on the hybrid system have been a success in the test bed but the real nail-biting situation will arise when Jag installs the system into a chassis to make a functional prototype.

If Jaguar succeeds this phase, then hypercar fans, start clearing your bedroom posters for space...
