Interesting.

GM is not AUDI!:D

An effective diesel setup should help it to get great milage.

I would be all for it.

I never understood why the current LS vettes didnt atleast get DoD to shut off cylinders when you're cruising at hwy speeds.

Why do we keep wasting time talking about the fuel mileage the C6 gets? it great it's better then the new Cobalt my wife drives, this isn't the car that needs diesel.

Sure, it gets good milage for what it is.

I get 32-33 at 65-70mph...but I wouldnt mind getting 40+mpg either :)

I find it very hard to believe that your C6 gets better milage than the cobalt...it's either broken or your wife is WOT at all times.

Hey! Maybe we could put a 5th wheel set-up in the cargo area and I could use my vette to pull a camper! :crazy: :lolg:

Dual TURBO Diesel Corvette-----now you're talkin'..............I can just see a Corvette taking off in a cloud of tire (and diesel exhaust) smoke....NOT! Diesels are noisy, smelly, oily, rattle traps and do NOT belong under the hood of any sports car, GM or Audi.........

Supposedly it was tried. With the transmission in the rear the Corvette has a long driveshaft that caused problems. They weren't able to dampen out the vibrations.

You won't ever find a diesel under the hood of my Corvette. Even if the C7 came with a diesel engine (and if I bought one) I'd put a different engine in it.

WILD :thumbs:

It better get a lot better mileage when diesel fuel in
Jersey is running almost $1.00 more per gallon.

Have you been in a NEW diesel car that is built well? Audi or Mercedes? They are not the diesels of days past.

That is such an insane statement to make. "I'd never put a more efficient engine that makes more power under the hood of my sports car"

Just because it's a diesel (I know, scary) and you aren't used to it doesn't mean it isnt a better option. I bet you also wouldnt buy a hydrogen powered corvette or electric corvette, etc.... ?

:lol:

Interesting...I didnt know that.

Thanks for the tip...now when it comes up in conversation with some of my buddies we'll have something else to talk about :)

I took particular notice of the "doubling of horsepower"...I'm a long way from an engineer but doubling of mileage and doubling of HP on just an initial prototype does interest me. Imagine a hybrid using this technology combined with that of the Tesla electric and now you're talking!

A diesel engine'd Vette would probably be a ton of fun to drive, just think of the massive amount of torque it would have! And diesel engines make about 90% of their peak torque right off idle too. So the car would be an absolute blast to drive around town. Getting 50 MPG on the highway would be pretty sweet too.

I'm also open to the idea of future Corvettes having a hybrid motor in them, as long as it was still performance oriented. For instance, it could come with a 250hp gas engine along with an extra 200hp boost from an electric motor. The beauty of that is the fact that electric motors produce all of their torque instantly. So just like a diesel, it too would be a ton of fun to drive around town!

I know both of these ideas sound sacreligious to a lot of enthusiasts, but I'll pose this question to you. If you had the choice between no Corvette at all, or a Corvette with a diesel or hybrid engine instetad, I'm sure most people would choose to see the Corvette live on with one of those alternative powerplants!

You are apparently stilll stuck in the 1980's.....

Well thanks for the affirmation..........but have you heard a brand new Dodge pickup pull up next to you recently? I can't stand either the noise or the smell.......I can't imagine have a Corvette smell that way with the top off or the windows down...................ick! And of course that really attractive oily fuel that turns to sludge during a freezing winter here? No thanks.......

Even Audi is having trouble working out the details of a road going version of the car. They are trying to figure out how to deal with a variety of issues - mostly boiling down to the added weight of the car, and some packaging contraints centered around not just the engine, but drivetrain components that can handle 750 lb ft of torque.

It's all about the Corporate Average Fuel economy!

They will have to either eliminate the poor performers or do something drastic with them (Trucks/SUV's) and make the high mileage vehicles even higher MPG.

Hummer H2 won't be around much longer in it's current configuration, and several others like the TBSS, Gas powered 3/4 and 1 ton trucks

Lighter vehicles will prevail, like the Corvette, but with 25% more MPG.

If it happens, maybe we can get a group of diesel "Vettes together, slap on some snow chains, and go do "Ice Road Corvettes" on the History channel.

4K redline... No thanks. :leaving:

Oh, and don't forget urine... er... I mean urea injection!

One way or another, I do believe serious changes in the next 4-5 years are coming. Hopefully the general 'fun" aspects of the car will only change for the better. We'll see...

In the end, I think diesel will be the only realistic big mileage alternative for the gas engine. The diesel will allow the Vette to be a performance road car capable of long distance runs that most of us desire. Most alternative's may be able to pony up the performance, but not the mileage (read distance.) Of course, I would expect the C7 to have a gas motor as I don't expect the sky to fall in the next few years:crazy: .

Ahh yes, but WE have driveline components ready for 750ftlbs. ala ZR-1 Now only to build up the A6's..... 1/4 mi. guess with that kind of torque??? Call your Broker, get tire stocks while it's still cheap.:lol:

Guy's relax, I live in Sebring, Fl, the 12 hr of Sebring endurance race is held here, 2 years ago the Audi team brought their deisel prototype, they had done thier homework, the car is so quiet when it goes by at 160 mph all you hear is the wind and a little of the turbo, it does NOT SMOKE!!!!!!, the car is ungodly fast and yet it is detuned, so as not to run and hide from the rest of the prototype and gt classes.
I would deffinately buy a diesel vette if it would perform anything like the Audi!!!!!!!!!!!!
this year's race in march was also impressive both times they have run the 12 hrs, the following day they put them back on the track without any maintinance and run another 12hrs just to make sure the find all the bugs for the 24hr at Lemans, so yes I'm very impressed!!!!!!!!:eek:
and reliable!!!!!!!!!!!!:thumbs:

diesel fuel is more expensive than premium gas. For that reason alone, I would never buy a car with a diesel motor.

Its coming
 

Some time ago I brought this up, and I was surprice that most are living in the 80's when GM converted gas to diesel, I think it was done on purpose, so people will stick to gas, diesel on high performance cars and on the Vette will be here sooner than later:cheers:
http://forums.corvetteforum.com/show....php?t=1993877

do you remember when diesel was a lot cheaper than gasoline??
and do you know how it is made???
is it a byproduct of something, another fuel perhaps??
well the oil companys are just getting greedy!!!!!!!!

Let me guess, it's made out of monkey piss :crazy:

Was that a trick question, or do you really want to know?

Diesel & electric - interesting concept!

:party: Ding ding ding ding ding :party: ......we have a winner folks. :rofl:


Damn.....and I was going to say that. :sad:

*Yawns*... It could happen? The Corvette doesn't even have overhead cams because there is not enough space with the low hood line; putting a much larger, much heavier diesel engine there is not happening.
I think a smaller engine, direct injection engine is a much more likely proposition, perhaps with forced induction.

I don't care if it runs on gas or diesel as long as it flies like in the Jetson's

Some of the European manufacturers like Audi and Peugeot are running diesels in LMP1. Audi won at Sebring with diesel for about three years straight and at Le Mans for several years until Peugeot won last year with a diesel.

:iagree:

you sound like my DAD!! (very old)
Its that mentality that prevents real companies that know how to make a excellent diesel from bringing them to the US.

you are stuck in a time when diesels WERE the way you are describing.
NOW times are-a-changin'

diesels are MORE powerful, BETTER mpg, much higher TQ, far more dependable, and more durable, quiet, and ultra clean with the new ultra low sulfer diesel standard. and up until recently much cheaper to fuel..
all the major makers have diesels in other countries.
why do you think the Military uses diesel so much??

you need to do allot more research before you go spouting off junk like that. Have you even researched the Audi R8 TDi?? or other diesel racers?

i wouldn't expect the average vette buyer to want a diesel in a vette.

but you are just ignorant in this area.:smash:

Yes, I remember when diesel was cheaper than gasoline, then Bush Sr put an extra federal fuel tax on diesel.

I also know how it is made. It is the remnant after the lighter fractions of crude oil (gasoline and naptha) are distilled off in the refinery.

Now modern refineries can crack heavier fractions to make more gasoline. So they have a choice, sell the heavy fraction as diesel and heating oil, or crack it and sell it as gasoline. It takes energy to crack the heavy fraction to make more gasoline, so it isn't economical to do when gas is cheap, but as gas prices rise, it starts to make sense to crack more heavy fractions to gas, leaving less to be sold as diesel. That drives the price of diesel up too.

Yes and we a have a winner!!!!!!!!!!!!!:party:
It's all about making MONEY!!!!!!!!!!!!:thumbs: :thumbs:

So getting 25+% better fuel economy isnt worth paying 15% more?

The added cost of diesel does NOT negate the increased milage that is possible in any way. :thumbs:

I am OK with any diesel engine in a Corvette, as long as it performs.... and is a turbine!

Well again ---- thanks for the affirmation!...you probably don't remember how WILDLY successful the first round of GM diesels was --- I do.......and even the new diesels still stink and rattle more than conventional internal combustion engines (heard one start up cold??). Putting liquid or powdered urea (you do know what THAT is made out of, right?) into the car every third tankful is not my idea of pleasant either.......but you are right, the diesels have had incredible racing success recently, but not even Audi has been able to translate that to the street yet.....Ignorant?...no.....sceptical in the extreme? Definitely.
I am with the poster above --- a much heavier, taller engine like a diesel is simply never going to fit in the Corvette and still have anything resembling sleekness. Direct injection on a smaller FI engine I can believe..........Chill, dude!

Maybe GM is talkin to BANKS PERFORMANCE?

He lives to make diesel outperform gas.

I vote for Ethanol or Hydrogen...Eth has a higher compression potential and both are cleaner than dinosaur fuel.

Plus it would be kinda cool driving an H-Bomb :lol:

:thumbs:

Yes I didnt mean to sound like im flying off the handle, its struck a chord in me as that is the EXACT same argument my dad uses (father issues?) heh and he hauls a big ass boat all over with a v10 complaining about MPG.. but wont even consider a diesel.

Anyway, to answer your questions.. I barley remember the old nasty American made diesels (i grew up and was awaken many times next to one)

of course they are not as quiet and a gasser but the positive out-weight the negatives. I also know about having to add Urea:ack: sometimes to ULSD.

I love my old (97) dodge cummins and run everything through that engine.. and my own homemade Bio-diesel. and mix and match.
cutting fuel cost to almost free to drive. ( so this issue personal to me)
try that while getting 300Hp/ over 720Lb TQ, AND 20 MPG from a 4x4 Auto.!!:flag: :thumbs:

True about Audi not making RACING diesels to the street YET..
BUT Audi, Honda, Toyota, Nissan, VW all have extremely high quality passenger cars over seas and BMW has 2 models arriving very soon in diesel 5 series and and X series.

diesels arn't THAT much bigger than gassers, heavier.. yes
and finally, if they made a corvette (or any sports car) with a diesel, that was sleek and great looking I would DEFINATLY get one:smash:

It is truly ashame that you don't know what you're talking about. I own a Mercedes turbo dieseland several Vetts. The new turbos use high pressure rail fuel injection. They are quiet,do not smell and do not produce the old telltale smoke. They produce so much torque, you wouldn't believe it, with a mere 196 Hp. Single turbo. Immagine a TT with, say 500HP and 1000ftlbs of torque. Now that would be talking. Oh, by the way, to prove the point, Mercedes ran a TT diesel at Le Mans for 24hrs at 200MPH.
Put that in your pipe and smoke it.

its no use, he's very old school and has a closed mind set...:toetap:

:(

Buddy NO don't say that!!


*Hugs L98 engine while sobbing

A diesil Corvette is Never going to happen

I own a fairly large trucking company and own 40 Diesel powered tractors. The newest Caterpillar engines run so clean that you could literally put your head into the stacks and not smell any diesel fumes. But it's when you fill up is where I get turned off. First of all with the fuel filler in it's present location you will definitely get diesel fumes wafting into the interior, and they linger! Did you ever go into a station that sells diesel and look at the ground around the diesel pumps? Nasty.I definitely don't feel like tracking that into the car either. I'll keep the diesels in the trucks and the gasoline engines in my Vette!

GM could put blades where the front spoiler was and mow lawns too...

The New Diesels are fantastic.
I have a twin turbo V10 in my Touareg with 552 lb ft torque at 2,000 rpm's
Red line at 4,000 so you don't have to wait to develop the horsepower.
With just a chip it's over 700 torque.

I'm not a fan of diesel engines, but even I have to admit they're ideal for regular cars and regular drivers - the sort of people who would never dream of taking their cars over 3000rpm and run on part throttle almost all the time. For them the mid-range torque is great, and the limited rev-range isn't an issue.

However, I think most Corvette drivers have higher expectations of their engines:
1) Nice noise. When my neighbour starts up his Audi A6 diesel, I run to the door thinking a delivery van has arrived... And if Audi can't make an LMP race car exhaust sound interesting, what chance is there for a diesel Corvette?
2) Decent rev range. Look at a high-output turbo-diesel torque curve, and you'll see nothing below about 1700rpm, rising vertically to a dizzy peak at 1900rpm, then falling off fast until there's nothing left beyond about 4000rpm. So you have an effective rev range of just over 2000rpm, compared with 5000rpm for an LS3....
3) Light weight and compact. Diesels are big and heavy. Even if you can package them, it's going to affect handling. Less of an issue with mid-engine designs, but for a sleek front-engined car it's a big problem.

I think the progress made with diesel engines over the last 20 years has been truly amazing, but that doesn't make them the right engine for a Corvette.

Never say never.

Scroll down and you can see where the new 4.5L Duramax is compared to the 6.2L gas engine visually with a side and end view of the two engines laid over each other. The 4.5L Duramax could be a direct replacement for the LSx engines in the Corvette and with aluminum heads and narrower 72 degree V-angle, it won't be much heavier if any. The exhaust manifolds are cast integral to the heads and dump into the V of the engine directly to a turbo. The intakes are cast integral to the cam covers...oh yeah, it's a DOHC 4-valve engine like our ZR-1s.:cheers:

Nothing wrong with a diesel. I would love to see one in a vette. It would match my truck.

For You Gary W.
Check it out.:rofl: Your arm chair engineering needs a tune:willy:

I don't understand why 'Vettes are being faced with mileage panic. They get better mileage than most cars.

My Z06 gets typically 20 for a tank, with a mix of ~28 highway and ~15-16 city. I've no doubt the normal C6s are appreciably better (better Cd, less displacement).

Guys, thats pretty good mileage. Throw in DOD and I can't see why a normal C6, with its .28 Cd, relatively small frontal area, light weight, 2 wheel drive, etc. couldn't get an EPA of 20-22/30. Real world highway mileage of 33 or something like that.

Am i missing something? Did someone spike my coffee? Or is the 'Vette a gas-sipper the way it is and something simple, like DOD, could bump it into economy car territory?

Can you show me a torque of any diesel that has 90% of peak torque off idle? Not likely, since it would never pass emissions. Take a look at the torque curves of diesels and GM gasoline engines, and you'll see the gasoline engines have much flatter torque curves, and wider power bands as a function of maximum rpm.

Some time ago I brought this up.

`Tis a silly place....
Americans don't like diesel cars, Americans don't buy diesel cars, Americans will not buy diesel Corvettes. GM will not sell a diesel in their flagship car anytime soon, there is no money in it.
Your next gen Corvette engine will be an mid-4 liter, overhead cam, direct injection with a supercharger which will run on gasoline and get comparable mileage and torque as a turbo D-fuel engine. Unlikely to be above 5 liter because of impending mileage restrictions, but possible.
This is the engine under development, tell all your friends now so you can look real smart 6-8 years down the road when it happens. This diesel speculation is nonsense.

I agree, the fillup is the worst part, I guess I'd have to carry rubber gloves so I didn't smell like diesel all day.


the idiots in their big diesel pickups pouring black smoke out at every stplight aren't helping your case. I don't know if they remove the partical seperators or just run crappy tunes or do it because they like it, but it isn't helping the image of a clean burning diesel like the vw tdi's at all.

Diesel is a lot more expensive these days. That negates any fuel advantage savings.

Ahh yes, but WE have driveline components ready for 750ftlbs.

Never say never.

diesel fuel is more expensive than premium gas.
