Atomic Batteries To Power

turbines to speed; Jaguar has created a range-extending plug-in hybrid supercar that has a pair of gas turbine devices on board, just like that of the Batcar. Hopefully its future is more considered than Jaguar's previous supercar effort, the XJ220, which was dogged by controversy.

The C-X75, a unique engineering concept that was built to celebrate Jaguar's 75 years of being, wowed attendees at the Paris show. The electric supercar is a hybrid with four electric motors, and a lithium-ion battery pack recharged by gas turbines. There is a 50kg electric motor with a maximum output of 145kW for each wheel, and a torque total of 1600Nm. The C-X75 can accelerate from O-lOOkm/h in a claimed 3.4sec, and tops out at over 2OOmph (330km/h).

Jaguar quotes a six-hour home recharging time for the 19.6kWh lithium-ion battery pack. As for range, 110km is possible in electric mode, but with the two gas turbines fired up, the car can quickly generate enough electricity to extend touring to 900km.


The tiny turbine blade, developed in partnership with Blndon Jets, increases the efficiency of small gas turbines to the point that they can be viewed as a realistic automotive power source, says Jaguar. Each of the units produces 70kW at a constant 80,000rpm and yet emits only 28g of C02 per kilometre overall. Usefully, they can be run on a range of fuels.

Being 4WD, the supercar has the ability to vector torque to each wheel,

Track mode

In track mode the turbines provide power directly to the motors for a 330km/h top speed car, high-speed airflow is directed to the back of the rear wheels for increased stability. A carbon-fibre rear diffuser helps manage airflow and creates downforce, and a high-speed aerofoil and vanes in the exhaust improve the flow of gases under the car.

Jaguar may claim sentimental reasons for creating the C-X75; however, the concept points not only to a new styling direction for the forthcoming XK (and possibly a smaller sportscar) but also the company's desire to be a voice in the supercar world after the disappointment of the XJ220 in the early '90s.

touchscreen display, Jaguar 'Co-Pilot', is located in the centre console, and instruments in front of the driver relay information on gas turbine status.

Underpinning the C-X75 is an extruded and bonded aluminium chassis. The bodywork is also alloy to reduce weight, which has been kept to a trim 1345kg. With no conventional engine, the concept vehicle is apparently shorter (4647mm) and lower (1200mm) than a conventional supercar.

Aerodynamic efficiency is a special feature of the C-X75. The front grille and brake cooling vents only open when needed, while at the rear comers of the

SAAB has released pictures and details of its first all-electric vehicle, the 9-3 ePower. The company describes the ePower as 'the first practical family wagon with all-electric propulsion' and claims a range of 198 kilometres. A 70-strong test fleet will apparently be built, due to start real-world, data-logged trials in Sweden at the beginning of 2012. This prototype will not make it to production, but the modified floorpan is to be used as the basis for Saab's new 'Phoenix Architecture', which will underpin the next-generation 9-3 and 9-5, opening the way for fully electric versions of future medium- and large-car ranges from the auto maker.

JAGUAR is testing a British-engineered flywheel hybrid that promises an extra 6okW power boost and up to a 20 per cent fuel economy improvement. Packaged into the rear axle of an XF test prototype revealed at this week's Low Carbon Vehicle event at Millbrook, the hybrid features components from British engineering specialists Flybrid Systems, Torotrak, Xtrac and Prodrive, plus input from Ricardo, and is being evaluated as an alternative to battery hybrids for storing waste energy during braking. The £3111 project is dubbed the FHSPV - that's Flywheel Hybrid System for Premium Vehicles - and is funded to the tune of around £2.2m by the government's Technology Strategy Board.

SUBARU plans to fit its upcoming rear-wheel-drive coupé, as yet unnamed, with a turbocharged 2.5-ntre engine. Subaru sources in lapan had previously said a 2o6kW version of the turbocharged 2.5-Utre flat-fourfrom the Impreza WRX STI's would be used. The new option will give it more power
