Não estou convencido quanto ao posicionamento dos faróis dianteiros (mas pelo menos não são iguais aos da restante molhada). Fora isso... é lindo.

Não ocorreu que usassem as turbinas como geradores. Brilhante! São pequenas, leves, eficientes, como servem de gerador o lag é irrelevante e como já foi dito podem queimar de tudo. E 780cv a puxar 1350Kg!

Venha ele e muitos parecidos!

Marca britânica está a estudar a viabilidade financeira da produção do «concept car» C-X75, revelado em Paris

A Jaguar está a estudar a viabilidade financeira da produção de máquina de sonho baseada no estudo revelado na última edição do Salão Automóvel de Paris, o Jaguar C-X75. A receber «luz verde», o desportivo será produzido numa edição especial e limitada.

Projectado para assinalar os 75 anos da histórica marca britânica, o C-X75 é capaz de alcançar os 100 km/h em 3,4 segundos, aos 160 km/h em 5,5 segundos e aos 300 km/h em meros 15,7 segundos. Para isso, conta com quatro motores eléctricos colocados nas quatro rodas que debitam, cada um, 195 cv (potência combinada de 780 cv) e um binário combinado de 1600 Nm (!).

Mais interessante é o facto de o C-X75 não ser um puro eléctrico mas sim um híbrido “plug-in” pois a autonomia em modo totalmente eléctrico não ultrapassa os 110 quilómetros.

Para estender a autonomia, a Jaguar usa duas micro-turbinas a gás montadas atrás do habitáculo e que podem utilizar como combustível gasóleo, biofuel, gás natural ou GPL. Estas turbinas podem carregar as baterias e aumentar a autonomia do veículo em 900 km, distância suficiente para viajar de Londres a Berlim com um único depósito ou, quando em modo “Track”, disponibilizar potência suplementar directamente aos motores eléctricos.

Os planos da marca prevêem a produção de 1000 a 2000 unidades/ano, a partir de... 2018!

• Direct technology transfer from top-level motorsport
• Prices from £700,000 depending on local market and taxes
• Exclusive limited volume hybrid supercar – only 250 will be built

Jaguar can today confirm that it will launch the remarkable C-X75 concept car as an exclusive hybrid supercar.

Jaguar C-X75 will become the British marque's most advanced model to date. It will offer performance on a par with the fastest production cars on the market, while adopting cuttingedge technology that offers remarkably economical running. Jaguar expects this hybrid supercar to deliver incredibly low CO2 emissions of less than 99g/km while being able to achieve in excess of 200mph.

"People expect Jaguar to be innovators - that is when Jaguar is at its best," said Adrian Hallmark, Jaguar Brand Director. "The C-X75 received an incredible reception as a concept car. We've been building on that momentum and there is a clear business case for this exclusive halo model. No other vehicle will better signify Jaguar's renewed confidence and excellence in technological innovation than this."

Project C-X75 will be the ultimate expression of Jaguar design and engineering innovation. This high-performance hybrid supercar will stay true to the initial concept design study that made its debut at the 2010 Paris motor show, while fulfilling requirements that allow it to be homologated for road use.

"We were always determined that the Jaguar C-X75 would be as striking on the road as it was in concept form," said Ian Callum, Director of Design, Jaguar. "This will be the finest looking and most innovative Jaguar ever produced. Even in the world of supercars, we can still produce the most beautiful."

In an unprecedented move, Jaguar C-X75 will be developed in association with Williams F1, who will provide their engineering expertise in areas including aerodynamics, carbon composite manufacture and hybrid technologies. This association will be at the leading edge of British automotive engineering and innovation.

"Confirmation of this project today signposts Jaguar Land Rover's continued determination to embrace new technologies," said Jaguar Land Rover CEO, Dr Ralf Speth. "A supercar like the C-X75 is the logical choice to showcase cutting-edge design, intelligent use of new environmental technologies and motorsport-inspired performance."

It also marks a new milestone in both company's histories as Jaguar Land Rover and Williams F1 collaborate for the first time to produce one of the world's highest performance and environmentally sustainable supercars. The production of Jaguar C-X75 will create more than one hundred highly-skilled jobs in the UK.

A direct technology transfer between elite motorsport and road-going production cars is key to C-X75's success. The supercar's chassis will be made of carbon-fibre to create an incredibly lightweight, yet rigidly strong structure. Aiding the transition from concept to production vehicle is the choice of powertrain. Jaguar continues to develop the use of the micro-turbine technology that was showcased in the original concept C-X75. Jaguar's parent company Tata has taken a significant stake in Bladon Jets, and will develop this very advanced technology as a medium-term aspiration that will play a part in Jaguars of the future.

To bring Project C-X75 to showroom reality within the timescales of a conventional model programme, an equally innovative powertrain had to be developed. The road-going supercar will use a state-of-the-art, small-capacity, highlyboosted internal combustion engine with one powerful electric motor at each axle.

"The engine's compact size allows it to be mounted low in the car for optimum weight distribution and to retain the concept's stunning silhouette. This will make the Jaguar C-X75 a bona fide hybrid supercar capable of silent electric running with an extensive EV range in excess of 50km," explained Bob Joyce, Group Engineering Director, Jaguar Land Rover.

When C-X75's motors and combustion engine combine, it will be one of the fastest production cars in the world, with a sub-three second 0-60mph time and a top speed in excess of 200mph. Crucially, this performance will be generated alongside incredibly low emissions, with a target of less than 99g/km CO2, thanks to Project C-X75's lightweight construction and cutting-edge powertrain technology.

Williams F1 has been at the forefront of motorsport engineering for three decades. The project engagement on Jaguar C-X75 is testament to the team's ambitions and will bring together two leading lights of the UK motoring industry.

"Our new association with Jaguar Land Rover provides us with an exciting opportunity to work with one of the motoring world's most famous and iconic brands," said Sir Frank Williams, Chairman of Williams F1. "Williams has always considered itself an engineering company and so this project will allow us to combine our technical expertise to create something truly exceptional."

Jaguar C-X75 will redefine the customer experience, and will set new standards in sales and after-sales services that will be recreated across the range in the future. Only 250 examples will be built, each costing between £700,000 - £900,000 depending on market and local taxes.

"Never before has the company launched such an ambitious, world-beating vehicle programme," said Carl-Peter Forster, CEO Tata Motors. "This is the Jaguar of the future. The opportunity for innovation like this in the UK is part of the reason Tata Motors invested in Jaguar, and it's fantastic that products like the C-X75 can now become reality."

From today Jaguar will be taking expressions of interest via its website (www.jaguar.com) or via its dedicated Project C-X75 contact service on the following numbers:

Afinal não usarão os motores a jacto que tinha no prototipo.

Pois não, ao que parece vão utilizar um motor de combustão interna derivado da F1, nomeadamente o 1.6 turbo que a Williams F1 utilizará.

La nota de prensa de la confirmación del C-X75 de Jaguar era vaga en muchos detalles, y nos dejó con algunas dudas, que, en parte, Jaguar España nos ha resuelto, y en otra parte, hemos averiguado a base de tirar de contactos. Lo primero que intentamos aclarar es el tema de la mecánica. El proto, como bien recordarás, contaba con dos microturbinas encargadas de recargar las baterías en marcha, y conseguir de esta manera una mayor autonomía del vehículo sin recargas ni repostajes de por medio.

Pues bien, las "prisas" de sacar este coche al mercado (2013), han hecho que se vaya a contar con otra opción para el "extensor de autonomía". Esto no quita para que se continúe el desarrollo de las microturbinas por parte de Jaguar, que además ofrecerá algunas unidades del C-X75 con ellas instaladas, pero de manera más puntual.

¿Y cuál es la alternativa a las microturbinas? Pues bien, todo parece indicar que será un motor de combustión interna derivado de los utilizados en la "nueva" Fórmula 1. Concretamente, el 1,6 turbo de inyección directa, con "muchos" caballos, y co-desarrollado con Cosworth, siendo empleado por Williams F1.

¿Y qué pinta Williams en todo esto? La involucración de la escudería británica parece más importante de lo que a simple vista podría dar a entender. Además de ofrecer el conocimiento de la fabricación y diseño con materiales compuestos, también integrará varias tecnologías propias de la F1 en el desarrollo del coche, como un completo y complejo estudio aerodinámico para el coche, uso de frenos y suspensiones derivados de las carreras...

Pero todo va más allá, y es que según varias fuentes muy próximas al proyecto (incluso de dentro de Williams), Tata podría estar interesada en invertir en Williams, y hacer de ella su "equipo de F1", con nombre Jaguar probablemente. Pero Frank Williams y compañía no están por la labor de vender todo el negocio, así que podría darse un acuerdo que acabara con un Williams Jaguar F1 a partir de 2013, con motores Cosworth, y decoración "british racing green". No suena mal, nada mal.

Usará []

Actualmente a F1 utiliza motores V8 atmosféricos de 2.4l.

A partir de 2013, há a intenção da FIA (nem sei se não estará já no papel, provável que sim) de a F1 passar a contar com motores de 4 cilindros 1.6 Turbo mas a medida não tem sido propriamente unânime, por isso, espero para ver se vai mesmo avante e, se não for, como vai ser este projecto.

Jaguar C-X75 hybrid supercar news update: here in 2014 | Automotive & Motoring News | Car Magazine Online

Jaguar today confirmed it will bring a limited, 200-strong edition of the C-X75 hybrid supercar to market in just three years' time.

The C-X75 is being developed in partnership with Williams and will be the second British hybrid supercar – alongside McLaren's new P11 – to challenge the Ferrari Enzo successor and Porsche 918 e-sypercars.
Jaguar C-X75: the latest news

Coventry today confirmed to CAR that just 200 C-X75s will be built in a low production run. The first production cars are expected around 2014.

The big news today was the engine: a turbo- and supercharged 1.6 petrol engine developed by Williams will provide the power. It's a techfest, sporting direct injection, twin-charging and a stratospheric 10,000rpm redline.

This charismatic powertrain was shown off to selected media today. CAR's Gavin Green was present and will blog on his experience later this evening. 'It sounded like a crazed motorbike engine,' he said.
Jag C-X75: the new generation of hybrid supercars coming soon

'And the car never runs on petrol power alone – the 1.6 is always boosting the electric motors or it can run in EV mode at speeds up to 40mph around town. It's clearly aimed at the McLaren, Ferrari and Porsche and it seems they want to be the most efficient of all.'

Although no kerbweight has been issued, Jaguar confirmed the C-X75 would have a full carbonfibre body to keep the mass to a minimum.

5 protótipos rolantes

5 protótipos rolantes

Antes de pôr o carro no mercado, parece que a Jaguar irá construir 5 carros de modo a certificar-se de que este modelo consegue atingir todos os objectivos estabelecidos pelo posicionamento e preço.

O desenho do carro terá apenas alguns ajustes, mantendo a forma geral e melhorando apenas alguns aspectos, como o refinamento.

O conjunto propulsor deverá debitar um valor acima de 500 cv de potência máxima, devendo o 1.6 fazer 10 mil rpm. O carro recorre a um compressor que entrega mais binário antes das 5000 rpm, recorrendo a um turbo para atingir a potência máxima depois das 5000 rpm, para além disto, o carro recorre a injecção directa de combustível e recorre a tecnologia de competição para a engrenagem da árvore de cames.

Jaguar is building five C-X75 plug-in hybrid electric hypercars to validate its performance target. If they're satisfactory, says Bob Joyce, Jaguar Land Rover's group engineering director, the project will get the green light.

"The business wants to put this car into volume production but it has to meet all its targets for positioning and price," Joyce said to Motor Trend at a powertrain demonstration.

Projected price is "£700-900,000 ($1.1-1.4 million) plus local taxes," and it would go on sale about 2014. The business case calls for 200 units sold.

In contrast, Porsche is aiming for 918 examples of its 918 Spyder, at [euro] 645,000 ($800K) plus tax. Joyce says he isn't especially worried about Jaguar meeting its targets. Ultra-wealthy collectors will buy one of each car that is credible. "The decision to go is defined not just by the competitors. These cars are defined by what they stand for."

The performance targets Joyce enumerates are eye-popping. Zero to 60 mph in under 3.0 seconds, and 0-100 in less than 6.0 seconds. The EV range is 60 kilometers (37 miles) on the Euro drive cycle, and the Euro CO2 measure must be fewer than 100 grams per kilometer. The electric motors are powerful enough to accelerate the car to 60 mph in 6.0 seconds, even in EV mode with the combustion engine off.

The final car will look much like the gorgeous and highly praised concept car from the 2010 Paris show. "It's absolutely the same shape and form, but with more edge and refinement," Joyce explains. The main changes are additional cooling apertures.

Like the concept, it's a PHEV with electric drive to front and rear wheels, with one substantial change: The concept used a pair of small turbines as range extenders. Joyce says these aren't ready for prime time, so the production car will have a gasoline reciprocating engine, linked to the wheels with a seven-speed automated manual transmission.

Jaguar wanted something that would publicize its forthcoming family of high-output, downsized four-cylinder engines. The C-X75 takes that concept to the extreme (and, in fact, is a unique bespoke engine, sharing no parts with that high-volume family). It's a 1.6-liter unit that goes to 10,000 rpm and makes over 500 horsepower, says Jaguar, courtesy of a supercharger providing torque below 5000 rpm, and a turbo spooling out high-rev power, and both direct and port gasoline-injection systems. It uses a motorsport-type gear drive for the camshafts.

The car received engineering expertise from Williams Grand Prix engineering, where the project team is based. This gives access to top-level race tech in aerodynamics, chassis dynamics, and composites. (The car has a carbon-fiber tub and skin, but aluminum front and rear crash structures.)

Most of all, the car benefits from Formula 1's kinetic energy recovery system development. The front and rear electric motors, which are the axial flux type, are three times as powerful for a given weight and size as any other car traction motor, Jaguar claims, with a greater rpm range than the conventional radial flux type.

The lithium-ion batteries use F1 control technologies for greater charge density. The pack weighs only 440 pounds yet has a capacity of more than 15 kW-hrs. Jaguar refuses to give the exact capacity, because, according to project director Paul Newsome, "We're very aware our competitors are taking actions and are interested in what we're doing." To reduce thermal loss, the battery and motors run at an extremely high 600 volts. The battery can run at an output power of "more than a quarter of a megawatt for an extended period," says Newsome.

The rear e-motor and the gas engine are separately clutched to the input shaft of the rear seven-speed transmission. This means the car can run in pure EV mode or combined hybrid mode. The four-cylinder engine and automated manual are light and compact. The AMT is said to save more than 200 pounds over a dual-clutch transmission. Lightness is vital to offset the battery mass, and compactness means there's unobstructed airflow through the rear diffuser.

The front e-motor is permanently coupled to the front wheels, using a single gear that approximates to sixth for the rear gearbox. Because of this, it takes a progressively higher share of the torque as speed increases. So the car has a high rear torque bias at low speed for better agility, but more stability at high speed as the front wheels take a greater share.

Because it needs to work in EV drive mode, the climate control is a new system independent of the engine. Power steering is also electric. The brake pedal actuates the servo directly; there's no brake-by-wire intervention. Newsome says that would have given potential extra efficiency, but "We've never tried a brake-by-wire system that feels natural." Another challenge is to synthesize an exciting noise for the EV mode.

The main challenge with the prototypes is to ensure satisfactory cooling. The design simulations called for 11 heat exchangers, composed of nine radiators (charge air, motors, power electronics, battery, A/C, engine oil, transmission, and two for engine coolant) plus two engine intercoolers. Unfortunately this leaves no room for a luggage trunk, so the engineers aim to combine two radiators and create space.

They are adamant that the cockpit package must not be compromised. Space, decent visibility, and a straight-ahead driving position are claimed to be non-negotiable.

Clearly, Jaguar and Porsche are thinking the same way. Both the C-X75 and 918 have batteries mounted low and centrally, and longitudinal engines in concert with a rear e-motor driving seven-speed transmissions, plus a single-speed front motor. But the Jag is a four-cylinder forced induction with 500-plus hp, and the Porsche is a naturally aspirated V-8 with 570 hp. The Porsche uses a DCT; the Jaguar, an AMT. The main difference is the electrical system. The Jaguar has at least twice the battery capacity, hence more electric range, and electric motors of something like twice the power. It's more of an electrically biased car than the Porsche.

Jaguar C-X75 enters 'critical phase' | Autocar

The 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-X75’s 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 car’s 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-X75’s 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 firm’s 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 drivetrain’s 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.

“We’re entering the critical phase of the project,” said Hallmark. “We’ve 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”.

Jaguar C-X75 axed

Jaguar has axed the C-X75 hybrid hypercar in response to the global economic crisis

The Jaguar C-X75 supercar has been axed. Global brand director Adrian Hallmark confirmed that the decision not to put the radical hybrid into production had been taken due to the current global economic crisis.

Five working prototypes will continue to be developed until next May. Up to three of these will then be sold at auction, while one will go into a future Jaguar museum and the other will be kept by Jaguar for running demonstrations.

"We feel we could make the car work, but looking at the global austerity measures in place now, it seems the wrong time to launch an £800,000 to £1 million supercar," said Hallmark. "This is backed up by other products from us that people are screaming out for."

The C-X75 was first revealed as a concept at the Paris motor show in 2010. Its hybrid drivetrain included a pair of gas turbines to power the car once charge from the four electric motors, one mounted at each wheel, had expired.

In May 2011 Jaguar confirmed the C-X75, which features the firm's first bonded carbonfibre chassis using Williams F1 expertise, had been signed off for production, albeit without the gas turbines.

The original drivetrain had been replaced with a turbocharged/supercharged 1.6-litre petrol engine and two electric motors, mounted at either end of the car, driving transaxles and powered by a liquid/air-cooled battery pack.

The combined power figure of the hybrid drivetrain was 888bhp and combined torque 590lb ft. The C-X75 could crack 0-60mph in 2.8sec and promised 0-100mph in less than 6.0sec. An all-electric range of 60 miles was quoted.

Hallmark said the undisclosed investment in the C-X75 would not be wasted, and 60 per cent of its technology would filter through to future Jaguars. The hybrid technology, he said, could be used on a three-cylinder engine to give it the power of a six-cylinder engine.

The C-X75's sophisticated aerodynamics should also influence future Jaguars, while the high-pressure supercharger technology could be used on future performance Jaguars with four-cylinder engines.

Hallmark said around 100 expressions of interest had been taken in the C-X75, with the maximum number of cars to be built capped at 250.

The C-X75's carbonfibre chassis was developed with the Williams F1 team. Hallmark said the relationship with Williams would end in May when the project died, but he expected the pair to work again in the future.

tendo em conta que este nicho estava a ficar cheio (918, P1, novo enzo), será que acharam que já não dava espaço para encontrar 250 compradores?
