The Trident Iceni Grand Tourer is purported to offer top-of-the-line performance and amazing fuel efficiency. So what's the catch?
A cheesecake that helps you lose weight. Beer that cleanses your liver. Some things are just too paradoxical to be realistic. But in a world where everything your heart desires involves some kind trade-off, a plucky British automaker is trying to bring us the ultimate in have-your-cake-and-eat-it, too.
After years of stalled efforts, the Trident auto company has announced that they will soon introduce a revolutionary production-ready model called the Iceni Grand Tourer. Packing a 430 hp diesel engine and a top speed of 200 mph, it's a scorcher capable of going from 0 to 60 in 3.7 seconds. Yet it will also boast one of the best fuel efficiency ratings out there, with a combined city and highway rating of about 70 mpg. The popular eco-friendly Toyota Prius hybrid has a rating of 50 mpg.

So not only will it rival your neighbor's Porsche but it'll can also outgreen your treehugging hippie friend's hybrid. And being that it runs on bio-diesel as well, the Iceni GT can be powered using a wide range of fuels from regular diesel to "mineral diesel, bio diesel, palm oil and linseed oil," according to a press release.
I don't know what kind of engineering dream team Trident has assembled, but it's hard to fathom how this is even possible -- even with a car that runs on diesel. And though Trident has released some basic specs, they've been coy about what kind of secret sauce they've got running under the hood.
What we know so far is that the car's relies on a 6.6-liter turbocharged diesel horsetrain that, when combined with Trident's innovative Torque Multiplication system and proprietary transmission technology, delivers 430 bhp and a staggering 950 lbs ft of torque at under 3250 rpm. Roughly speaking, this means that cruising at a constant 70 mph, the specially tuned engine will run at just 980 rpm, produce 700 lbs ft of torque and keep on going for over 2,000 miles with just one full tank of fuel.
For an extra cost, buyers can also upgrade to a 660bhp model that delivers 1050lbs ft of torque.
The Trident will be on display at the Salon Privé 2012, an annual car show held at West London's Syon Park in early September. The company plans to start taking orders shortly after with a starting price of $119,000.

I found it a great reading and I wish good luck to Trident Auto Company to make the best energy efficient models and rank them higher. http://www.national.co.uk/information/winter-tyres.aspx
Hi, I really need the information more as you have provided in this valuable blog. http://www.sellyourcarfast.com.au/sell-my-car-for-cash/

Pretty looking car. Unfortunately, probably sucks to drive in any inclement weather. I don't see any roof, or any setup for installing a roof. Why can they not make a car that gets 50-100mpg and tops out only at 100mph. That is the most ANY family would need n a daily basis. RE: Pickup trucks - yes there is a place for them, but for "mom" to be driving a HEMI "dualie" to the corner market to pick up some milk is supremely ridiculous. I live in town and my neighbours have 2 (TWO) huge pickup trucks for daily commutes, etc. Why? Because that is what everyone else is driving these days, and bigger means better, right? $200 for each fuel fill-up is insane! It only costs me $45 to fill my 2000 Olds Intrigue, and I still get around 36mpg. If I could, I would drop a diesel and advanced tranny in it in a second.
Seems to be the combination of a huge engine, with a very high-tech transmission that lets the diesel run as a diesel should; at a very low range of low rpms. The low-speed torque is because the engine itself is huge, and the tranny lets it step down suddenly when more torque is required. Done seamlessly, this ought to do it. Wouldn't be surprised, however, to see a smart torque-return system incorporated into the tranny.
"IF" these do go into mass production, where will you take it for service ? I'd be leery of having one, and find out I have nowhere to take it for service/repair. Also, as one poster mentioned, are these MPG claims in US or Imperial gallons ? One imperial gallon is approximately equal to 1.201 U.S. gallons. Personally, I'm with another posters thoughts. Build me a full size pick-up that has the torque and power to PULL something. I'd even settle for "JUST" 50 MPG and say 100MPH top end.
Great. We have an efficient car that may sell 100,000 units due to price. Big green savings! We need these cars to be sold in the millions to make a green difference. The price has to be under $30,000 to sell big numbers.
As a physicist and energy management consultant, I always start with energy considerations. Is there enough energy in a gallon of fuel to run the car 70 miles? With careful driving and a well-designed, lightweight vehicle, the answer is yes. Can it be done with normal driving in a combined city/highway cycle? Doubtful. Can it be done while having fun with all that acceleration or driving at speeds over 100 mph? No! I want to see some actual performance numbers accompanied by a description of the driving conditions and verified by a competent, reputable organization other than the manufacturer.
My comment is related to the drive line of the automobile. The transmission in the vehicle could be an infinately variable a hydrostatic drive that provides an infinately variable ration transmission that can be adjusted at random to any input rpm to output rpm within the capability of the unit that was selected for this vehicle. Overall efficiency of these units is approximately in the low to mid 90% when new. Other possible options for infinate variation is electric servo motors, or variable belt drive units.
You can bet it doesn't get that kind of mileage when it's going 200 mph. Not that remarkable, really. Light weight, low drag... probably shuts down most of the cylinders when it doesn't need the power.
You guys don't get it. Who cares if some little yuppie race-car can go really fast and use less fuel. How about a 1 ton, diesel powered pick-up truck that has the horse power and torque needed to tow equipment to a job site. This has value and results in savings to businesses that create jobs and make things work for those of you who are concerned about and can afford a "useless" sports car that can do nothing more than haul you ass around.
Back in the mid to lat 1960`s there was a car a called a Morris 1000. It was a zippy little box on wheels that was fun to drive. We got 57 miles per gallon on Imperial gallons. A little later a friend bought a diesel VW Rabbit and got around 50 MPG Imperial gallons. If he had coughed up some more cash he could have got a model with a higher gear or overdrive and that would have given him very close to 70 mpg imperial. There seems to be some mystique about getting better gas mileage, not sure why. I`m also wondering about the makeup of the car described in the article. How much does it weigh? That would have quite an influence on fuel consumption. One of the cheats on carbon emissions in automobiles seems to me to be air injection into the exhaust manifold. Yes it would help burn up fuel that escaped being consumed in the cylinders. It also dilutes the carbon emissions in parts per million going out the tail pipe where the government vehicle emission checkers hook their machines to. Something really fishy there. You can have a horribly inefficient engine look terrific under those circumstances. I'm hoping this new car contains some real improvements in engine design. Too many lazy automakers just trying to get product out without thought.
Wouldnât a 2000 mile range and 70 mpg equal about a 30 gallon fuel tank? That seems exceptionally large. Again, Smart Planet needs to do some editing. PS There are several reasons for relatively poor gas mileage (I had a 80 VW diesel that consistently got 50 mpg) Some of those reasons for poor gas mileage are government mandated, including emission mandates, fuel mandates (ethanol) and safety mandates (impact protection, 5 mph bumpers), some are customer comfort mandates, (AC, power windows, etc)
Secrecy doesn't mean they don't have anything. Breakthroughs in fuel/engine technology - any technology for that matter - must be closely guarded. If they do not yet have safeguards in place (patents, etc.) to protect their innovation from thieves - and there are plenty of them - they would naturally not want to be specific about it. Has no one making these accusations ever heard of Apple? Or Microsoft? Just to name a few.
Using modern, high-end lubricants, better ignition parts (spark plugs, etc), better air intake, better exhaust, and decent tires my old 1990 Geo Storm got upwards of 50 MPG highway. My 1995 (admittedly terrible) Mitsubishi Mirage S (basic coupe) gets upwards of 43!! SOHC Saturn SC models got something like 45+. There's a sports car called the Avion that gets upwards of 100MPG. Look it up. The problem is that somewhere along the line past the mid-nineties we just plain forgot how to build engines. America suffers from not only collective amnesia but an incredible brain drain as we have incredibly lousy engineers at the corporate helm. We focused on bigger, louder engines with no real increases in any kind of efficiency, getting to the point where my parents think that an absolutely pathetic 20+ MPG highway is "really good". Of course the car in this article can get 70+ MPG with these kinds of specs. It's just plain good engineering. Also, look at the smooth lines and curves - less drag means more efficiency. I'll also bet you the vehicle doesn't actually weigh all that much.
Just like there's an entire underground of people doing hybrid and electric car stuff, there are groups concentrating on Diesel mileage (on their Jetta TDIs for example) and getting some pretty impressive numbers.
