Tech Ride: Amazing Jaguar Power Plant For Its Porsche 918 Spyder Rival

Jaguar has shared details of the engine that will make its way between the fenders of the upcoming C-X75 hybrid hypercar. The Porsche 918 rivaling horsepower comes from a twin-charged (supercharger on the intake-side, turbo on the exhaust side) 1.6-liter four cylinder revving to an electrifying 10,000 rpm. The engine, co-developed with Williams, features direct injection and will apply the F1 team's knowledge of the KERS system to this eco-friendly rocket ship. Though production of the first Jaguar hypercar since the XJ220 isn't scheduled until 2014, the engine is currently undergoing dyno testing at Jaguar's Coventry facility. Someone at Jaguar was kind enough to record and release this clip of the engine at full song and it sounds phenomenal (warning: you may want to turn down your speakers/headphones this thing is loud). It reminds us a little bit of the Lancia Delta S4 with all sorts of whining, and whistling combined with the unmistakable fury of a motor with a serious Napoleon complex.

The engine itself is pretty advanced compared to the Lancia Delta S4, benefiting from 30 years of technological evolution. The 16-valve, all-aluminum engine features dry sump lubriation, direct fuel injection and port injection. The unique twin-charging system works in tandem with the belt driven supercharger working to produce low-end power then switching to the single turbo at 5,000 rpm. The setup, according to Jaguar,  minimizes turbo lag at low rpms while reducing drivetrain loss to the supercharger as the revs approach the 10,000 rpm red line. There's been no word of an official horsepower figure, but the gas engine alone will produce at least 500 horsepower.

The 1.6-liter unit is aided by the power of two axial flux electric motors, one on the front axle and the other mounted on the rear axle. Jaguar claims that the electric motors are three times as powerful as conventionally-sized electric motors. All that instant torque and horsepower in a carbonfiber shell will make the C-X75  an amazing performer. We should expect the run from 0 to 60 mph to be completed in under three seconds, and the run to 100 mph over in just six seconds. The party is set to end at an estimated 205 mph.

The C-X75's hybrid technology is on the bleeding edge, with its liquid cooled batteries producing a shocking 600 volts and weighing a scant 400 lbs. Sitting mid-ship, they serve as the bun to the meat of the screaming gas powered engine. In electric-only mode, the halo Jag is capable of speeds in excess of 40mph with a range of 37.5 miles.  With such a spectacular sounding motor, you'd have to be mad to ever shut the thing off. Our guess is that most owners of this $1.25 million ride can afford to hear this kitty purr all the time.

All of that power is transmitted through a single clutch seven speed gearbox mounted transversely, just like the Pagani Huayra. The electric motor mounted on the front axle is geared to make the C-X75 an AWD car which helps make the sprints to 60 mph and 100 mph so blisteringly quick.  The body employs further use of the Williams F1 team's know-how. Constructed entirely of carbon fiber and aluminum, the C-X75 will likely be one of the strongest and lightest cars when it goes on sale in 2014. No official word on the weight, but it's a safe guess that heads will roll if this Jaguar doesn't tip the scales at less than the Porsche 918 Spyder's 3800 lbs.
