Trident Iceni - 70 mpg @ 70 mph and 375 hp

[Daox]

A coworker sent me this link. Very impressive specs. Not a bad looking car either.

Price - around £60,000 ($78,500 US)
Engine - 6.6 liter diesel V8
Weight - 2690 lbs
Aspiration - turbocharged
Torque - 520 lb-ft @ 1800 rpm
HP - 375 hp @ 3100 rpm
1/4 mile - 12 seconds
0-60 mph - 3.9 seconds
Top Speed - 170 mph (electronically limited)

*68.9mph at a constant 70mph was the first recorded test at Millbrook Proving Ground. The figure naturally improve at lower speeds – at 30mph, Trident's initial tests returned 108mpg.

...The Iceni is a traditional grand tourer. With a full tank of diesel, you can expect to travel around 2000 miles without needing to fill up.

...at 70mph, the Iceni is running at 980 rpm whereas the average car runs at between 2500 and 3500 rpm at 70mph.

Can't wait to find one used. I think the biggest issue with driving one is waiting to fill the tank up and guessing when you will need to wait to fill up with the winter blend to prevent clouding. Also I guess I might confuse when it needs a fillup and when it needs an oil change.

As an off-roader..... [drool] I want that engine, lots of torque at the low end. I bet the engine is half of the cars weight though.

Throw a diesel in a Vette and there ya go (there's a thread on that here somewhere).

This also throws those BS arguements out the window how a diesel that is large enough to have the same power as a gasser will be less efficient.

Seems like I remember saying more than once that a diesel is efficient throughout its load range, even at very low loads. I suppose I will see someone here say the diesel vette clone only gets 70mpg because the diesel fuel has 20% more energy ?

[Daox]

Well, a diesel still looses efficiency at lower loads, just not NEARLY as bad as a gas engine. The BSFC charts show it all. As you can see in the example below, the gasser's peak efficiency is roughly equal to the efficiency of the diesel at ~30-40% load.

Yes it shows that I rather have a waterfall than a pinpoint BSFC. Easier to hit somewhere on the mark that way.

I wonder if this is Imperial gallons? It would still be impressive, just not quite AS impressive.

"Their fantastic fuel economy is achieved through technology called torque multiplication and it can be applied to all diesel cars"

"Torque multiplication keeps a car's rev range low. It is this that decreases fuel consumption and reduces emissions. For example, at 70mph, the Iceni is running at 980 rpm whereas the average car runs at between 2500 and 3500 rpm at 70mph."


I think they have an interesting transmission and the driver will need a bit of training to use it effectively.

Please carry on,

I suspect you're correct. That would give it a 56 mpg reading in normal gallons, not the convoluted British variety .

I've seen pics and read articles of big diesels in sports cars, and the mpg figures have always been no less than impressive.
