The thing about turbine engines, is that they go through far more rigorous tests then any conventional engine.

Imagine a conventional engine as a High School student preparing for a 100meter dash.
A turbine engine is a like person who is preparing him self for a 400meter dash at the Olympics.

If you compare service intervals between a conventional piston engine vs turbine engine, then you can clearly see that a turbine engine can work for longer hours and under heavier loads far longer then your standard engine.

I thought that Turbines traditionally get horrible economy.

16 gallon tank, 68 miles on electric only. So that is 560 - 68 = 492 miles with the turbines spinning / by 16/gal tank = 30.75mpg, and I would assume that this would be using the hwy estimated mileage that will be on the EPA sticker.
All those engines make 780 horsepower and 1179 torques
I would say that they went a little over board though. Each electric motor weights 110lbs. So x4 that is 440lbs in electric motors. Then you have to figure in the twin turbines, weight of the diesel and the batteries. All that just for the engines + fuel.


0 to 200 in 17.5 seconds.
I'd love to have one of these things though for sures! [thumbup]

Turbines have a range where they aren't so bad, but if you used them directly for drive they'd almost never be n that sweet spot.

I imagine with a good computer and software having a drive motor for each wheel will make this thing crazy on corners + that acceleration and top speed it might break a few track records.

Pity it doesn't have look like it'll have killer down force however.

So than why did you say that the range is 560 miles?

Its range should be 628 miles.


oh, battery packs weighs 400+ lbs. Almost the same as the electric motors. Plus diesel fuel, plus 2 turbines, this engine combination weighs over 1,000lbs.

Each turbine weighs 110 pounds, + 400 pound battery pack. So 620 total, producing 780bhp and 1170 torque. That is it though. No radiator or any of the other added weights necessary on a typical engine, plus weight savings in the transmission make it quite acceptable, especially given the fuel economy. Diesel is heavier than petrol, but not that much. All super cars have large fuel tanks, so that point is completely mute.

Its nice but the new Lamborghini Sesto Elemento concept car is insane!

I am not a fan of that rear end with the exposed diff case but the overall updated Gallardo look and shape with that interior is awesome. Plus the performance is just sick

If they put elements of this car into the Gallardo replacement it should be amazing!

Apparently Boeing helped Lamborghini with the carbon fiber materials for the car, kind of ironic when it was Lockheed Martin that made the Stealth fighter

The trend i noticed with Lambos, is that the designers take an Axe and just whack corners off the car and make it look awesome.

At some point all conventional engines will die off and all mechanics will have to take a quick course on new tech.

the only problem i can see with turbines is not only the exhaust temp and N2 temp is also the rotation speed - in the event of an accident `what if` theres an uncontained failure . that will get very very messy.

we`ve had 2 uncontained failures recently - one on a qantas 747 and the other on 787 001 whilst testing.

Where did you find that? 110lbs for the turbines? You also forgot the 4 electric motors.

Motortrends link says 110lbs x 4 electric motors + 400lbs batteries = 840lbs before turbines and diesel fuel that will weigh around 100lbs with a full tank. Could easily weigh 1,200lbs before figuring in the transmission. The turbines are watercooled, so there will be a radiator.
Shoot, at least it is still getting 30mpg.

I expect the turbines are air cooled, just like every other turbine I know off.
Why do you and the other chap include fuel - you wouldn't worry about it with a 'convenjtional' engine.

Red, service intervals for turbines are very long, j7st make sure they have a good supply of clean oil - regarding a catastrophic failure, remember the mass is still very low and so containment is easy. Consider a turbo-charger failure, even a large model at over 100k rpm does little damage.


Thing I would be concerned about would be the potential noise levels...
