Tråd: Jaguar C-X75 træder ind i afgørende fase

Jaguar hypercars fremtidige besluttes hybrid drivaggregatets tech træder næste fase af developmentThe Jaguar C - X 75 ind i en kritisk fase af sin udvikling, som vil i sidste ende beslutte, om den radikale hypercar vil gøre produktionen eller annulleres.
Jaguar har haft C-X75s komplekse hybrid drivetrain kører på et prøveanlæg for de sidste tre måneder og er nu klar til at sætte det i bilen for at skabe en fungerende prototype.
Denne del af udviklingen er helt ukendt, indrømmede globale brand direktør Adrian Hallmark på det seneste Los Angeles motor show. Som sådan, sagde han, der er en ansvarlig spørgsmålstegn omkring fremtidens biler.
Vi ønsker at gøre det, men indtil vi ved teknologi vi kan ikke klare, tilføjede han.
Når først afsløret som et koncept på 2010 Paris show, inkluderet C-X75s hybrid gearsystem et par af gasturbiner til at drive bilen når afgift for de fire hjul-monterede elektriske motorer var udløbet.
I maj 2011 bekræftet Jaguar C-X_75 - hvilke funktioner virksomhederne først fæstnede kulfiber chassis, bygget ved hjælp af Williams F1 ekspertise - var blevet underskrevet for produktionen, dog uden gasturbiner.
Den oprindelige gearsystem var blevet erstattet med en turbo og kompressor 1. 6-liters benzinmotor og to elmotorer - en i hver ende af bilen, og hver kører en transaxle.
Tidligere på året Jaguar afsløret drivetrains første officielle tal. Den blæst 1. 6-liters motor ville have så meget som 500bhp og ville rev til 10, 000 rpm. Elektriske motorer ville være den mest magtfulde i verden og drevet af en meget sofistikeret flydende og luftkølede batteri.
Den forreste motor vil køre kontinuerligt gennem en enkelt-trins gearkasse kraftoverførsel forhjulene, mens den bageste motor ville engagere sig med en skræddersyet syv-trins automatiseret manuel gearkasse til at yde kørsel til baghjulene i samarbejde med motoren.
Jaguar citerede en alle-elektriske vifte af 37 km, sammen med en 200-plus top hastighed og en sub-3. 0sec 0-60 mph tid, mens CO2-udledningen blev vurderet til mindre end 99g/km.
Mens alle denne teknologi fungerer korrekt på test senge, Hallmark sagde den virkelige test vil komme, når det blev overført til kørende prototyper.
Ind i kritisk fase af projektet, sagde Hallmark. Weve været en smule reserverede og holdt tilbage fra kommunikere det fuldt ud.
Fremtiden for projektet er nu mindre klar end det var sidste år, men Hallmark sagde bilen ville stadig være bygget, hvis vi har et niveau af tillid i teknologi arbejder sammen.

Jaguar hypercars future to be decided as hybrid powertrain tech enters next stage of developmentThe Jaguar C-X75 is entering a critical stage of its development, which will ultimately decide if the radical hypercar will make production or is cancelled.
Jaguar has had the C-X75s complex hybrid drivetrain running on a test bed for the past three months and is now preparing to put it in the car to create a working prototype.
This part of the development is absolutely unknown, admitted global brand director Adrian Hallmark at the recent Los Angeles motor show. As such, he said there is a responsible level of question mark surrounding the cars future.
We want to do it, but until we know the technology we cannot be clear, he added.
When first revealed as a concept at the 2010 Paris show, the C-X75s hybrid drivetrain included a pair of gas turbines to power the car once charge for the four wheel-mounted electric motors had expired.
In May 2011 Jaguar confirmed the C-X75 - which features the firms first bonded carbonfibre chassis, built using Williams F1 expertise - had been signed off for production, albeit without the gas turbines.
The original drivetrain had been replaced with a turbocharged and supercharged 1. 6-litre petrol engine and two electric motors - one at either end of the car and each driving a transaxle.
Earlier this year Jaguar revealed the drivetrains first official figures. The blown 1. 6-litre engine would have as much as 500bhp and would rev to 10,000rpm. The electric motors would be the most powerful in the world and powered by a highly sophisticated liquid and air-cooled battery pack.
The front motor would run continuously through a single-speed transmission powering the front wheels, while the rear motor would engage with a bespoke seven-speed automated manual gearbox to provide drive to the rear wheels in tandem with the engine.
Jaguar quoted an all-electric range of 37 miles, along with a 200mph-plus top speed and a sub-3. 0sec 0-60mph time, while CO2 emissions were rated at less than 99g/km.
While all this technology is working successfully on test beds, Hallmark said the real test would come when it was transferred to running prototypes.
Were entering the critical phase of the project, said Hallmark. Weve been a bit reserved and held back from communicating it fully.
The future of the project is now less clear than it was last year, but Hallmark said the car would still be built if we have a level of confidence in the technology working together.
