Thanks for the link. It's a concept so it doesn't really exist but it does look interesting. Tks.
 
Rather than allowing Toyota to improve on GM's design...GM should just bring it to market first.. get the profits and take the glory.

You still don't get it. It's not cost effective. There is a "concept" called point of diminishing returns. And small hybrid diesels are past that point right now. Say if fuel costs go to $5.00 per gallon then maybe. A Hybrid diesel like the Opel should conservatively get 50 mpg combined. It's non-hybrid version 40 mpg. That is a 25% increase. At $5.00 per gallon that's $0.125/mile non-hybrid and $0.100/mile for the hybrid version. Over 150,000 miles the difference works out to be $3,750 in fuel costs savings. That will take 6+ years to recover the initial costs at $5.00 per gallon, longer at $3.00. At $3.00 per gallon it works out to $2,250 for the same 150,000 miles. Not practical!! Advanced engines which are more efficent like the Scuderi design are better solutions and are easier and more cost effective to Hybridtise. Now this is my estimate on when you will see this engine in production and used in a production vehicle. 5 years. Shortly after most manufactures get their diesel models to pass US EPA emission standards. When it comes to doing business glory has nothing to do with it. It's all dollars and cents. You can't eat glory.

The Prius wasn't cost effective when it was first introduced in 2000 but Toyota took the risk so that by next year they will havesold nearly a million of the hybrids.
 
Seriously now, Maybe that is the very point of all of this. GM should bring this to market in the same way Toyota and Honda did in 2000. Take the risk. It looks good. It'll probably get great gas mileage. Just Do It.
 
Since 2000 Toyota and Honda have shipped nearly 1.0 Million hybrids and gathered all the good press and probably some profit. They took the risk. If the GM product is more than a skin over an idea then put it on the market. If they keep dragging their feet then Toyuzu and Honda and Renault all will have the diesel hybrid here first, making money and getting the good press.
 
Now if it is just a skin over an engineer's dream then maybe it's not ready for the road. You can bet that in 2010 a Toyuzu diesel hybrid will be here. Gm better have this Opel ready as well.
 
GM faithful are dying for GM to do something dramatic, like the Saturn announcement this week, to show that GM understands the surge of buying interest in fuel efficient vehicles.

Isn't this vehicle being introduced in Europe? If so then gas prices would have to go down to hit $5/gallon. Actually I've never understood why manufacturers are making hybrid versions of these already fuel efficient vehicles like the 40 mpg Opal. Take a 20 mpg vehicle and increase its fuel efficiency by this same 25% and you'll save twice as much money on fuel.
 
When people talk about not recovering the hybrid premium they seem to rarely mention the resale value. If you get rid of your car after 3 years it will probably be worth about 50% of what you paid for it. So at that time you recover half of the hybrid premium.

About 74 mpg US plus 20 miles in all EV mode - BRILLIANT !!
 
I'd buy that car today if it were for sale in the USA.

Too bad this car never made it into production.
 
Hybrid diesel 4-dr sedan, 108 MPG in the year 2000.
 
GM Precept
 
The hybrid-electric Precept is driven by a battery-powered electric traction system that moves the front wheels, and a lightweight, 1.3-liter, 3-cylinder diesel engine in the rear. The direct-injection engine, featuring turbocharged compression ignition, was developed by Isuzu Motor Co. Ltd., one of GM's Asian affiliates.

Hmmm..... now Toyota owns this share in Isuzu that GM used to own. That's very interesting since it was announced that Toyota and Isuzu would have a hybrid diesel out in 2010.

Good point and connection.....
 
Looks like Toyota now has that engine, and they already have had the hybrid side, so all they gotta do is put 1 and 1 together, and with their superior HSD technology over whatever GM had in the Precept......we might get 110-120 MPG in the diesel/electric hybrid they build.
 
KDH, will you sell me one of these when they build it ???

Yep right after I get mine.
 
My Prius will be 5y.o. then and have about 200,000 miles so I'll be ready.
