Much has been said about the upcoming C-X75 from Jaguar , but now we have some real, tangible news. The hybrid supercar will be fitted with a 1.6-liter turbocharged inline-four capable of, apparently, 500 horsepower.According to Autocar, the diminutive engnine is able to acheive this output through twin-charging, or the employment of both a supercharger and turbocharger. They are able to boost power at varying RPMs, thus making for a wide powerband. Oh, and speaking of revs, the engine is said to redline at a towering 10,000 RPMs. Jaguar engineers estimate that the eco-friendly performance machine will achieve a top speed of 200 miles per hour, and 0-60 time of below three seconds. That should put it in the same neighborhood of the forthcoming McLaren P11 and Porsche 918 hybrid-supercars. Jaguar is developing the C-X75 with Williams, and intend on producing only 200 examples. The first of which is said to roll out in 2014.The supercar never runs on gas alone, as the mid-mounted four-pot constantly charges up the 600-volt battery pack. The battery sends power to a pair of electric motors that allow the vehicle to run in full EV mode at speeds of up to 40 mph.The price for all of this high-tech low-emissions gadgetry? £700,000 to £900,000, or $1.1 million to $1.4 million based on current exchange rates.
