We have a diesel pinglist? Cool.

Could you please add me? Thanks.

“Huh, I have no problem getting parts. Even O’Reilly’s sells them.”

I didn’t have trouble finding the parts, I had trouble paying for the parts. Maybe 300D’s are easier, I see a few driving around town.

Hahaha! That’s just the thing, I can’t kill that 5 cylinder turbo diesel that’s in it now. The interior is bad and someone hit my front bumper, but the engine just keeps on ticking...

[2ndDivisionVet]

Probably, it seems like the sportier models are more expensive at purchase and from then on.

[Red Badger]

Done!................

If you live at 5,000 ft and drive higher in the mountains, a turbo is the only way to go.

Toyota has had a popular diesel for some time, just not available in the USA of course.

Was curious about the non-functional hood scopp on my 4Runner. Turns out it is functional with the diesel option.

[doorgunner69]

scopp = scoop on the hood of course.

Jeep Grand Cherokee EcoDiesel with the V6 turbo.

30 mpg and crazy towing capability.

[truth_seeker]

Thanks. Is that a Chrysler engine with some history?

For the metrically challenged, 130kw and 450N.m converts to 174.3HP and 332ft/lbs. That's stump puller torque.

Toyota has been rumored in recent years to be looking at putting their Hino turbo diesel in a one-ton 'Tundra HD 2500'. They even did a mock-up of it at a trade show:

Hino Motors is Toyota's industrial truck divison. They make the Aisin transmission that the high end Dodge Ram 3500 Cummins HO (6.7l inline six: 385hp, 865ft/lb torque) uses.

Toyota basically has a Cummins-level prime mover engine/drivetrain combo that could tow even the biggest and heaviest fifth wheel toy hauler: 32,000 GVWT. That's 16 tons towing capability. The wicked Cummins HO only supports 15 tons and anyone who needs that kind of towing capability is like a hero to me. That's just SICK towing capability.

They just need to put that Hino mill in a Tundra that has a chassis can handle a military-marine grade drivetrain. If they do, they'll sell every one they make.

(Side note: Most powerful engine I've seen on the road was a Volvo D13 inside a two million dollar Prevost luxury coach that had some 1600+ ft/lb of torque and was towing a 30-foot trailer behind his 40 foot RV. Jeeminy jumpin' jehosephat, and it even got 9 mpg with a range of more than 1000 miles. Just absurd power: 13 liters of howling turbo diesel.)

The US govt has seem to want to do all it can to keep clean diesels out of the US. From whatever sources. Too afraid it will cut into the diesel supply for truckers, and too afraid it will improve the numbers for fuel efficiency without being a pet pc way to do so (hybrid/electric/hydrogen).

I am not much of a conspiracy follower. I learned a few years ago that over half of new passenger vehicle sales in Europe were diesels.

Very clearly VW/Audi, BMW and Mercedes are positioned with a variety of diesels in the US, all the way up the model-price range.

The one and only diesel passenger vehicle from the former big three is a Chevy Cruse.

You’re right — Toyota styling at the moment is awful. Funny because sometimes Toyota really nails it.

This is what we have been waiting for.

The new EcoDiesel V6 Turbo is a Volkswagen-designed engine made in Italy. It's new for this year:

"... VM Motori Cento in Ferrara, Italy, produces the engine, which will be marketed under the EcoDiesel name. It features a block of compacted graphite iron and aluminum twin-cam heads. Basic specs for the 60-degree six include common-rail injection, downstream emissions treatment via urea, a 15.5:1 compression ratio, and ceramic glow plugs so quick to heat up they might well consign mentions of glow plugs to history. Adding to the allure of the diesel is that, like the 2014 GC’s gas-fired engines, it is backed by a ZF-designed eight-speed automatic." (Source: Car & Driver

So, you have a twin-OHC rail-injected turbo diesel with urea filtering (it's this goop you add to a reservoir) that has 240 horsepower and 420(!) ft/lb torque, gets 30mpg HWY, an 8-speed automatic, and has a range of 720 miles on a single tank. The Jeep GC can tow 7500 pounds too. Bet even the 4x4 model still gets mid-20s even towing a 3500 pound trailer. And at 420 lb/ft torque, it's gonna surprise a lot of suckers at a streetlight drag race getting whooped by a Jeep crossover wagon.

They start at $29k. Personally, I think it's a deal and I'm a Toyota guy. Like another poster said above, anyone not buying the turbocharged model of a vehicle when a turbo is available is making a pretty sad mistake.

[The KG9 Kid]

To my mind, I think you're right.

There's no way I'd choose the gasoline motor in a vehicle I wanted where the factory also offered a turbo diesel option. The turbo diesel mill is invariably going to be designed and manufactured -- part for part, compared to the standard gasoline engine option -- like it was developed in the aerospace/military division of whatever company it came from.

The only downside to owning a diesel is the maintenance service cost. Now THAT... That can be hefty. I admit that.

Only reason I'd seek a gasoline vehicle is if it were a whiz-bang supercar that needed to rev to 9,500 rpm and do 10 seconds in the quarter mile. I'm not in the market for a car like that.

[Sequoyah101]

But we can’t have one here in Amerika.

[truth_seeker]

VW/Audi are leaders in consumer vehicles using diesel.

Obviously Fiat-Chrysler-Jeep have done their homework.

Enjoy.
