Default Jaguar C-X75ís To Feature Four-Cylinder Turbo With More Than 500 Horsepower

Quote:
The production version of Jaguar's stunning C-X75 concept is on track for its scheduled debut late next year, albeit without the conceptís original jet-turbine technology. Instead, Jaguar will go with a conventional internal combustion engine paired with a plug-in hybrid system.

However, as journalists invited to Jaguarís test facility in Gaydon, England recently found out, the engine featured in the production C-X75 will be like none other found in a production car on sale today.

The engine will be a four-cylinder unit displacing just 1.6 liters but developing more than 500 horsepower and revving past the 10,000-rpm mark. This will be made possible thanks to a myriad of technologies including direct fuel injection as well as supercharging and turbocharging.

The engine will either drive the rear wheels via a seven-speed single clutch transmission (picked for its lightness) or generate electricity to charge up the carís lithium-ion battery pack. This battery will then power a pair of electric motors, one at each of the axles, and combined the system should be able to accelerate the car from 0-60 mph in under 3.0 seconds and see it reach a top speed in excess of 200 mph.

The setup will also enable multiple driving modes, including all-electric and hybrid modes, but curiously no gas-only setup. According to Autocar, in electric-only mode the car will have a range of 37 miles and 0-60 time of less than 6.0 seconds.

In isolation these figures are quite impressive, but there are at least three other hybrid supercars claiming to offer similar performance, so the Jaguar will certainly have its work cut out for it. Some of the rival models include the highly anticipated Ferrari Enzo and McLaren F1 successors as well as the Porsche 918 Spyder.

Only 200 examples of the Jaguar are scheduled to be produced, with pricing for each likely to be in the vicinity of $1 million.

agreed. I know in the past they have talked about reliability issues but my land rover is going 65k+ miles without any issues.

The latest XJ is a beauty.

Didn't Jaguar learn with the XJ220, nobody wants a tiny turbocharged engine in a supercar. No matter how awesome it is.

Oh, and 500hp is weak.

500 hp seems like a lot but for an f1 derived engine with an big turbo I thought it would be even higher. Not that it's not impressive but I was expecting near a full race engine. The current f1 engines are 2.4 liter v8 that produce 750 whp and they do that detuned so they all have about the same power and the old 3 liter v10 produced over 1000 whp

I'm wondering how long the engine will last? 1.6 and 500 ponies must be a lot of boost.

Sounds like a nightmare if anything goes wrong, but hey that's why you sell before the warranty's up, right?

On one hand, it's not unheard of to boost a 1.6L to that power level on the aftermarket. So with a team of car engineers building and tuning every single component to spec, it should be alright. On the other hand, Jaguar.

there is no car manufacturer in the world who sells a 4 cyl engine with a turbo at this power level....and now letīs ask why...

Supercars aren't bound to the same maintenance cost or interval constraints as cars for us plebes.

Yep. The XJ220 also suffered from tons of lag iirc.

I wouldn't be surprised to see the same thing happen in this car.

The Jaguar C-X75 is no more

Sad news – the British hybrid supercar will not make production. Ollie Marriage reports

It is with great regret that we have to inform you of the death of the Jaguar C-X75. The British hybrid supercar, first seen at the Paris Motorshow in 2010, and which you can listen to here, was due to enter production next year, the firm intending to build 250 cars each costing close to £1 million.

That now won’t happen, and economic reasons are to blame, principally the fact that Jaguar no longer believes it can make an “adequate return on investment”.

Linked to that, inevitably, is the current global economic situation. “By the time we got to market with this, we expected normality to have returned”, said brand director Adrian Hallmark, “and even though we could carry on and could fund it, it’s not a major part of our investment. When we look at the global environment and the austerity and the difficulties being faced out there, to bring to market an £800,000-£1 million supercar just feels wrong”.

This is a great shame, denying us the chance of seeing the C-X75 line up against the holy trinity of 2013 hypercars: Porsche’s 918 Spyder, McLaren’s P1 and Ferrari’s new ‘Enzo’.

It would have been a fascinating battle, because Jaguar, in conjunction with the Williams F1 team, had made great progress with the C-X75. True, the proposed jet engines had been ditched (they worked beautifully, apparently, but emissions in the start-up phase were too high), but the turbocharged and supercharged 1.6-litre four cylinder was producing a reliable 500bhp and the electric motor specially developed for the project weighed just 23kg, had a mere 17 moving parts and was compact enough to fit in the space required by a single cylinder, yet developed 295lb ft.

That was to be driven by a “revolutionary” liquid and air-cooled battery pack, capable of an unassisted range of 60 miles. In total 17 radiators and a total intake area of 1.5 square metres were needed to keep things cool and allow the car to run properly. And the quoted figures were impressive: 663lb ft of torque and up to 900bhp. What this would have meant for performance was a 0-60mph time of 2.8secs and a 0-100mph time; “quicker than a Veyron”, according to Hallmark. Top speed was forecast at 205mph, and predicted emissions were sub 100g/km.

However, while all these figures are now largely meaningless, the technology behind them isn’t. Jaguar is claiming to have learned a massive amount during the C-X75’s development, enough to be able to use many of the elements in future projects.

Expect the 295lb ft super-compact electric motor and battery to appear in a hybrid concept before too long, and further down the line to possibly replace one of the cylinders in a range extender model.

The small capacity engine looks destined for a bright future, with Hallmark saying, “the new engine family that we are developing for production in the Wolverhampton plant will be able to use the high pressure, supercharged, turbocharged systems to give us high performance versions of four cylinder engines”. Incidentally, the team has looked at possibly creating a V8 by mashing two of these fours together…

All in all, Jaguar has 100 patents relating to the C-X75 and claims that “at least 60 per cent of what we actually spent… will be recycled into our road cars.”

Besides the powertrain technology, this includes carbon brakes and a method of casting alloy wheels that removes 40 per cent of their weight. The C-X75 also featured some amazing aerodynamic solutions, including an exhaust blown diffuser. Again, Hallmark claims this has relevance for future sports cars. Likewise the jets, which Jaguar believes have relevance not just for future automotive applications, but for “domestic power generation”. Imagine: a turbine providing your hot water or electricity…

And for the time being, development is continuing. Why? Because Jaguar has five working prototypes and at the end of this phase – anticipated to be next April/May – is likely to sell two of them to private collectors. That will likely be done via auction, allowing the 100 people who had made serious expressions of interest to find out who really has the deepest pockets. Just two, instead of the 250 originally planned, but couldn’t we claim this as a production run?

Extremely high boost pressures = extremely high NOx levels = an engine like that won't be sold in the US, much less California on any street-legal vehicles.

Seeing as the car is dead before making it to the showroom floor Jag will once again have us waiting for them to produce a true supercar.

Anyways last time i checked, 4 bangers with that much power twin charged had 0 lag and as a result from them having all of that power they were deemed too dangerous for WRC and banned. If Jag wants to build a 500+ HP 4 cyl engine with a perfect torque curve to get the performance they are looking for they would go twin charged.

EDIT:
That video is new. My assumption of it being twin charged was dead on and now they are saying it will have 800 horsepower. GLORIOUS!
