New Cars Reviews : Jaguar C-X75 (2013)

New Cars ReviewsJaguar C-X75 (2013) This will be the 900bhp jaguar c-x75 supercar, an £800k rival for your own mclaren p1, porsche 918 spyder and laferrari – and we’ve driven it. That’s the excellent news. The bad news is jaguar truly cancelled the c-x75 project in december 2012, therefore the prototype we’ve driven doesn’t preview the production supercar, however instead tease us with what would possibly have been…

How does the jaguar c-x75 turn out 900bhp ?

The original c-x75 concept car ( unveiled with the 2010 paris motor show ) used 2 diesel-driven micro-turbines out to charge its batteries, that in flip powered four electric motors, one nestled in every wheel hub. Alas this potential powertrain proved somewhat too space-age, however jaguar’s different resolution isn’t specifically low-tech : there’s a supercharged /and/ turbocharged a regular. 6-litre engine using direct /and/ port-fed fuel injection, combined with 2 electric motors but a lithium-ion battery pack out to build a four-wheel drive hybrid supercar with around 900bhp.

Should jaguar have only slotted the 542bhp supercharged 5. 0-litre v8 due to xfr-s directly into c-x75, saved a few weight, and saved itself lots of technical headaches ? That raucous v8 merely wouldn’t fit at intervals the sleek silhouette, says c-x75 programme director rob atkin, and he and his team had four terribly specific objectives that precluded this jag supercar from getting a simple fossil fuel engine.

Those four objectives ? For your own c-x75 production car to own the very same look and appeal of one's original concept car ; for it to get 0-100mph in same time just like a bugatti veyron ; for your own co2 emissions out to match a toyota prius ; and for your own electric vary out to a minimum of match that of one's chevrolet volt. Quite a demanding list…


Therefore for your own jaguar c-x75 out to accelerate as arduous just like a veyron it required a a regular. 6-litre four-cylinder engine ?

That, apparently, is true. The slender form of one's c-x75 suggests that it can’t use a few monstrous quad-turbo engine much like the veyron, and as also a v8 won’t fit atkin and his team had to seem for one thing smaller. Conversely, when using the demands becoming a clean and inexperienced clearly as the prius and volt, the jag required a hefty set of batteries too.

Combine those 2 demands and you will end up by having dry sumped, all-aluminium a regular. 6-litre four-cylinder nestled behind the driver, and flanked on either aspect by lithium-ion battery packs. The engine revs out to 10, 200rpm, is supercharged ( for your own low-rev response of the naturally aspirated engine ) and turbocharged ( for top-end power ) and it also has direct and indirect injection : at lower revs and under partial loads the two main combine in and up to help the c-x75 be reasonably economical, however at high revs a second throttle body opens and each systems are utilized throw as much fuel as is possible directly into engine.


Beyond that the engine is mated to the 295lb ft electric motor but a seven-speed automated manual transmission, and within the nose there’s another 295lb ft electric motor out to drive the front wheels. The automated manual was developed as a result of it’s small and light ( far more therefore than the usual twin-cutch ‘box ) however the transmission truly has 2 clutches, one to alter gears with, and 1 out to disengage the engine due to electric motor for ev running. Shifts take 200ms ( the new 911 gt3 can shift in 100ms ) however the nose-mounted electric motor sends a few additional torque throughout the front wheels throughout the gearchange out to compensate for your own torque interruption onto the rear wheels.

Anything i would like to discover ?

The c-x75 concept was aluminium, however the c-x75 production car is utterly carbonfibre. Still, with all the batteries and motors aboard the kerbweight of one's production car was predicted out to solely only sneak below 1700kg – that’s like-for-like higher in comparison to the porsche 918 spyder, however a good bit heftier in comparison to the p1 and laferrari. The 5 prototypes aren’t quite that lithe though, and also the roll cage and testing and diagnostic equipment adds more kilos.

However despite the switch from aluminium out to carbon, the styling of one's production c-x75 has modified terribly very little. If something, it’s truly improved, when using the front grille now more akin onto the f-type, fuller flanks, but a more aggressive rear diffuser. It’s gained door mirrors too, and a pop-up rear spoiler-cum-airbrake, and also the standard doors of one's concept have morphed into fancy flip-up dihedral items. The fifth prototype, painted navy, is notably gorgeous.


How does the c-x75 drive ?

In ev mode it feels about as brisk just like a hot hatch – jaguar reckons it’ll do 0-60mph in around six seconds – and there’s instantaneous urge due to electric motors. It’s not really a silent experience either, just like a ‘sound synthesiser’ produces a distant rumble of huge generators ( like you’re inside the bridge of one's uss enterprise and might hear the warp core deep when using the bowels of one's ship ) and pulses a loud electric heartbeat whenever the c-x75 is plugged in and charging.

And also the thorough road check ? There are a couple of caveats. The 5 prototypes were built out to prove the technology, and also the next stage was out to develop the dynamic aspects of one's c-x75. Therefore though atkin says 50% of one's project was completed before finally it was cancelled, terribly very little of your work was on any ride or handling set-up.

With only a number of laps of jaguar’s gaydon check track allowed, what will we learn ? That the electric power steering ( the very 1st few application within the jag, however the very same system already for all the current series of vary rovers ) is light but is not wholly devoid of feel, that the adaptive dampers ( pinched due to f-type ) offer the c-x75 a reasonably compliant ride, which the gearshifts aren’t as instantaneous just like a double-clutch ‘box, however feel quicker than the usual lamborghini aventador nonetheless additionally less brutal. Bar the lights and exhaust system, all the mechanical parts are contained at intervals the c-x75’s wheelbase, you are doing notice the burden through what corners and bends we will notice. We suspect the porsche 918 ( with its rear-wheel steer system ) and also the mclaren p1 ( with trick hydraulic suspension ) can each feel more agile.

The engine is pretty special though. At idle there’s the rough chatter on your engine’s gear-driven cams, the shriek on your supercharger builds and builds till the purpose where it’s de-clutched at 5500rpm and it’s solely the turbo forcing air in the engine, then the deep snarl and growl on your exhausts very takes over and starts to firmly deafen you. Despite the little engine, at 10, 000rpm you’ll never suppose the c-x75 lacks any aural drama.

Is it as quick currently being a veyron ? More or less. I’ve solely driven the 1183bhp vitesse, that's shockingly fast, however the jaguar isn’t quite as brutally manic. However as we hit over 180mph connected to relatively short straight there’s no doubting the electricity, and along with the electrically assisted four-wheel drive the low-speed initial acceleration is significantly intense. Ditto those previous few moments before you can reach 10, 000rpm in every gear.



Laferrari. P1. 918 spyder. C-x75. Despite the four representing a brand new breed of supercars, all have become completely different, and therefore the jag had the potential to possess one of the technically advanced hybrid powertrain – however it’s solely one that’s been cancelled. And conversely, laferrari – with the use of a relatively standard 6. 3-litre v12, no zero-emissions mode as well as a hybrid system designed purely to firmly boost acceleration – is the major one amongst the quarter reported to possess sold out. Is that the worldwide market very willing for hybrid supercars ?

Where does that leave the c-x75 ? The 5 prototypes can proceed to be developed for your own remainder of 2013, as technology contained at intervals them is promised to firmly filter through onto forthcoming jaguars. The long run is bright for jag, however it'd are even brighter with the use of a real halo supercar.
