We don't use exclamation points all that often, but once in a while it's justified.
In this case, the Jaguar C-X75 Concept supercar just unveiled at the 2010 Paris Motor Show deserves one. If not several: !!!
Not only is it sleek, sexy, and stunningly beautiful (to our eyes, anyhow). It returns better than 30 miles per gallon of fuel on the European test cycle once its 68 miles of pure electric range are exhausted.
In other words, it's a very green high-performance car. Better yet, there's nary a piston engine to be found.

Four electric motors = 780 hp
Instead, the wheels driven by four 145-kilowatt electric motors, with the electronic control system providing torque vectoring on each wheel for maximum stabilty and traction control.
If you don't do metric, that's a total of 780 horsepower in motors. And the total torque is even more amazing 1190 foot-pounds.
205 mph, 68 electric miles
What does that mean on the road? The top speed of the Jaguar C-X75 is projected to be 205 miles per hour, with 0-to-62-mph acceleration in just 3.4 seconds and, even more impressive, 0 to 100 mph in a negligible 5.5 seconds.
A 19.6-kilowatt-hour lithium-ion battery pack--whose precise chemistry Jaguar is rather vague about--sits between the front wheels. The company quotes an electric range of 68 miles, after which a range extender kicks in to recharge the battery pack and flow power to the drive motors.
Two tiny turbines
That range extender is comprised of two 70-kW micro gas turbines, each just 22 inches long and weighing less than 80 pounds, spinning at up to 80,000 rpm.
The pair, provided by Bladon Jets and mounted at a downward angle behind the rear bulkhead of the passenger cabin, can operate either one at a time or together, depending on energy needs.
In addition to recharging the battery pack, the turbines can drive the electric motors directly when the C-X75 is set to "Track" mode for its highest speeds.
Part of the performance comes from the exceptionally compact and lightweight nature of not only the microturbine range extenders, but also the vehicle itself.
The C-X75 Concept is based on an entirely aluminum structure--one that contains, by the way, about 50 percent recycled metal. Your used soda cans never looked so good.
Jaguar has created a supercar that's shorter, narrower, and far lighter--it weighs just 2,970 pounds--than competitors from Lamborghini, Ferrari, and other famous marques.
Aggressive airflow management
The aerodynamics are aggressively managed, using the turbines' huge appetite for air as a way to keep the car on the ground at speed and manage outgoing airflow. In front, both the grille and brake vents have shutters that open only when needed, with a movable airfoil at the rear contributing to management of the turbine exhaust flow.
How much air do those turbines use? Running at maximum speed, each one uses almost 900 cubic feet of air per minute--or 15 cubic feet per second.
As well as running on any number of fuels--diesel, biodiesel, kerosene, and more--the turbines are efficient. Just 16 gallons of fuel provide almost 500 miles of range once the car switches into range-extending mode, or roughly 31 miles per gallon.
