Jay Leno's EcoJet - Click above to watch the video after the break

In a garage full of ultra rare, highly desirable cars and trucks, Jay Leno's EcoJet still manages to stand out as one of the coolest. Part of the vehicle's claim to fame comes from its ability to run on biodiesel fuel, putting out an impressive 750 horsepower and 700 ft-lb of torque at 48,000 RPM from its Honeywell LT101 jet turbine engine.

Underneath its distinctive carbon fiber skin lies an aluminum chassis that is kept in contact with the ground using existing suspension bits from the Chevrolet Corvette. Also in use is a four-speed automatic transmission from General Motors that gets its input from a custom gearbox that reduces engine speed from those aforementioned lofty heights down to 6,000 rpm.

Naturally, special carbon fiber brake discs from Brembo paired up with aluminum six-piston calipers were necessary to hold back the engine's 200 horsepower at idle. Inside, Microsoft built the dash, including a full Windows Vista-powered computer that is fully connected to the internet.

As we have come to expect from Leno, the EcoJet does indeed see action on the roads in California, and Jay also finds the time to visit the airstrip for a race against a private jet. Wanna know who wins? Click past the break to watch the video.

      thats one ugly car
        • 5 Years Ago
        UGLY! Really?!?!?

        I think it looks nice for what it is. It's no beauty, but I wouldn't call it ugly.

        "- One of us should have gone to spec savers?!?!?"

      Lucky! That car sounds like a freaken space ship rofl.
      • 5 Years Ago
      but has it gone around the Nurburgring yet?




      =P

        I wanna know when it can fly across the Pacific.

      carbon fiber brake discs eh? i'd like to see that in action.
        • 5 Years Ago
        Ok let me remove my foot from my mouth for a second and ask this: Is it simply a matter of nomenclature? If you look em up on the brembo website, NO WHERE does it say "carbon fibre." However, if you read about F1 brakes off the F1 website, it says the discs are carbon fibre composite. Could someone explain this?
        • 5 Years Ago
        You can. Formula 1 comes on early next Sunday morning.

        carbon CERAMIC people. CERAMIC.
        • 5 Years Ago
        @Trent, I think you're right. I thought they were carbon ceramic.
        • 5 Years Ago
        Carbon fibers can be used to reinforce many different types of materials. The fibers work on the same principle as rebar in concrete, but at a smaller size and larger scale. In most automotive applications the "concrete" is a plastic of some kind, but a heat resistant ceramic filler is used for brake pads.

        So to answer your question, the technical terminology is something like carbon fiber reinforced ceramic. In any case, I think "carbon fiber" and "carbon ceramic" brakes can be used interchangeably because they are both unambiguous shortenings on the correct term. Likewise, ricers should say their hoods are carbon fiber reinforced plastic, but that just doesn't have the same ring, now does it?

      i wonder whether they got the 750bhp from the jet fuel or the bio-diesel? they loaded both but only gave a figure. anw, that is loud! not sure i want to cruise on the highway in that though.
        • 5 Years Ago
        Jet Fuel and Diesel Fuel are essentially the exact same thing.
      • 5 Years Ago
      As far as I know, Carbon Ceramic is made from a material called Moissanite (aka Silicon Carbide). It's called a ceramic because it is manufactured in much the same way-via a cooking process.

      What would stop a small gas turbine from being hooked up to a hybrid system? It's always running at peak efficiency and can continuously charge the battery. An electric motor would also compensate for the lack of torque a small turbine motor would have, as well as eliminate the "turbine lag" that Chrysler's prototype units had.

      Chrysler's direct turbine-drive prototypes of the 60s were able to do 25 mpg back in the day, with lower weight, maintenance, and the ability to run on essentially any combustible liquid (including Chanel #5, apparently) with just an adjustment to the air/fuel ratio. I bet an electric car with an on-board turbine generator could do pretty well. Too bad Chrysler's the only company with any experience, and they're not in any shape to be doing significant R&D at the moment.

        i thought i read 25 mpg somewhere. hmm.

        you're thinking along the lines of a Prius type hybrid - what about a Volt style? A lightweight generator that runs at peak efficiency all the time to charge the batteries and generate electricity for the motor. Less dead weight to carry around, and a small turbine would likely be at least as efficient as a small ICE.

        Or maybe I'm wrong. I'd love to see someone trying something different.
        • 5 Years Ago
        What about completely doing away with the batteries?
        • 5 Years Ago
        Ayle - my knowledge of physics/electricity is limited, but I'd imagine that if you eliminate the batteries, the maximum power output of the electric motors would be no greater than the maximum power of the turbine, whereas if there's a battery to capture the "spare" potential energy generated by the turbine at maximum efficiency, then there will be more peak kinetic power available when asked for (power from turbine + power from batteries).

        The benefit of this setup over the Volt:
        - fewer parts in a gas turbine (lower maintenance costs)
        - likely lighter weight than an ICE (benefits in vehicle dynamics, potential benefits in fuel efficiency)
        - runs a variety of fuels without need for conversion

        Mazda's the champion of the rotary, Toyota's the champion of the Prius-type, developing other competing powertrain options could be cool...

        • 5 Years Ago
        I don't think so. Those early Chryco turbines got about 17mpg (US gallon).
        The engine only pulled 130hp but had 425ft-lb torque at stall.
        It was frickkin' slow....12 seconds 0-60. And extremely noisy too.

        Moreover, it isn't a good idea to use a turbine for intermittent power generation...frequent automatic starting and stopping isn't really an option.

      Windows Vista dashboard? I see the DOT and NHTSA instituting a different type of crash ratings...
      • 5 Years Ago
      Wow, that was an awesome.
      • 5 Years Ago
      Hey, if he produced it with the Windows Vista I can Imagine the crash test. When you crash, A window will pop up and say "Windows needs your permission to deploy airbag."
        • 5 Years Ago
        ......yawn......
        • 5 Years Ago
        There is no airbag.
