The top 10 Diesel Dogs

By | October 18, 2012, 3:05 AM PDT

The peppy Polo from VW is a popular diesel car. This one gets about 70 mpg.

That’s dog as in top dog, not what a dog.

And that’s diesel, as in what you can put in a car instead of gasoline in order to get better mileage and emit less CO2.

Despite its long running reputation in the U.S. as a big environmental blight, diesel fuel actually delivers a greater wallop per gallon and softens the global warming impact, compared to gasoline.

Of course, your car has to have a diesel engine, which perpetrates internal combustion without using spark plugs. Rather, it compresses air that heats up and ignites injected fuel. Not only does the diesel engine outperform the gasoline engine, but it lasts longer too.

Given America’s historical tendency - now changing - to turn its nose up at diesel, U.S. car makers have some catching up to do.

According to a new report from Pike Research, only two U.S. auto companies make the Top 10 list of  ”clean diesel” car producers, none ranking higher than fifth. “Clean diesel” is a standard that meets environmental limits for soot, nitrogen oxide and other choking, smog-inducing pollutants.

The list is dominated by, you guessed it, European manufacturers. German brands Volkswagen, Mercedes and BMW  take the top 3 spots in that order, followed by France’s Peugeot Citroen, all ahead of General Motors.

Europeans have long paid a lot more money per liter of automobile fuel than Americans have - thus the popularity of fuel efficient diesel vehicles on the Continent.

The Top 10, according to Pike:

  1. Volkswagen Group
  2. Mercedes
  3. BMW
  4. PSA Peugeot Citroen
  5. General Motors
  6. Renault-Nissan
  7. Ford
  8. Mazda
  9. Fiat-Chrysler
  10. Mitsubishi

The U.S. ain’t even Deputy Dog yet. But with a little more work, it should earn its star soon.

I've driven diesel passenger cars in Europe...
...where they've been a mainstay for decades, mainly because of their fuel economy in lands where fuel is usually twice as expensive as it is in the US. The first time I did, I was surprisingly impressed.

It's a shame that GM's cheap, under-engineered, half-hearted attempt at passenger diesel a back around 1980 poisoned Americans on the concept for over a generation. It's a good example of the consequences of attempting to deploy a not-ready-for-prime-time technology on consumers.

diesels
I owned a 1962 Mercedes diesel and drove it nearly 200,000 miles. I also owned an Oldsmobile diesel that was a disaster. Car ran well, but all of the cars I knew of blew engines--head gasket, wrist pins, bearings--the engine was destined to set diesels back a generation. I still love diesel engines, but not much is available in the US.

Clean Diesel
The GM Oldsmobile diesel of the '80s was a converted gasoline engine, and it was a disater. Don't judge diesel engines by and engine that wasn't designed to be a diesel.

If you take a fleet of new Mack Trucks with clean diesel technology, and drive them around Los Angeles, you could clean up a lot of the air pollution, because the exhaust would be cleaner than the L.A. air.

biofuel compatible, too
I bought a 2004 New Beetle with the hopes of running it on used french-fry oil. That did not come to pass, although there still is a small underground of folks making or selling biodiesel. The greatest surprise for me, however, was the performance of the car. The torque of its engine is amazing (and it outperforms its rival top-of-the-line VW gas engine).

I miss my '84 Nissan Sentra Diesel.
In 1984 I found myself considering my first diesel. It was in a Nissan Sentra equipped with a 1600cc engine. What caught my eye was the foot high yellow numbers 50/66 on the windshield. They lied. I rarely got 66 on the highway, usually on 4+ hour trips mileage was in the low to mid 70's. NE Ohio winters were not a problem starting the car. I was crest fallen when I discovered Nissan had stopped offering their diesel when it was time for my next vehicle. I sure wish American made versions were available today.

The Smart car has a diesel variation available in Canada but not in the US. WHY NOT?

Probably emissions.
The trick to the new generation of diesel cars is making them compliant with American emissions standards. The cost of making a diesel Smart car compliant was probably not worth the effort considering the number of them likely to be sold at their current price point.

Who decided...
Who decided that the trucks barreling outside my door should be able to blow black clouds of diesel smoke and I can't run a 1.0L diesel in a SmartCar?
Someone in Congress should grow some and challenge this nonsense.

Work already done in Europe/Japan
The work is already long done.

Diesel's amongst the lowest CO2 emissions, and with a Catalyst and Particulate filter also the cleanest.

If you are a performance nut, the V8 turbo-diesel's Jaguar/Landrover, Mercedes, Toyota, BMW etc have have more torque than a Bugatti Veyron. They also have very frugal units from 1 litre upwards through 3, 4, 5 6 and 8 cylinder versions.

Average Mile Per gallon in euro-diesels is 40-50mpg. The new version of SkyActiv Diesel's Ultra-High Compression diesel's from Mazda are even better.

Can You Answer This?
Why are diesel cars so popular in Europe and worldwide and almost NONE in the US?
I had a VW Golf diesel back in the 80s and it was a great little, cheaply-operating car.
How and why did the US ban diesel cars that operate fine in Europe?
I can't believe some of the trucks I see spewing soot everywhere and we are prevented from running small diesel cars?
I will welcome the option of a diesel car- but I won't hold my breath...

Mostly particulate emmissions.
Europe has much lower emissions standards than we do. (I find many cities literally unbreathable) It's only been relatively recently that clean diesel technology has been available market-wide. (good explanation below)

Diesel
We owned a VW rabbit diesel in Michigan. It was a brand new one with 4 doors and 5 speed stick. We used to get 50 mpg. It was a blast to drive and cheap to keep. We spld this for a new car for almost the same price we paid. I miss that a lot. Perhaps I will buy a new Jetta with a turbo Diesel this year.

Breath-taking Diesels
Diesel vehicles are breath-taking...literally. The UN just declared diesel exhaust as a "Known Human Carcinogen", raised up from the "Probable Human Carcinogen" category. Diesel vehicle owners should be responsible for the carnage they create, the same as someone creating an accident is.

Complex chemicals
Complex chemicals in all petroleum fuel's are known carcinogens.

It's all a matter of hazard v's risk.

Do you know the long term effects of household chemicals, cosmetics, medicines, food additives, food constituents (High Fructose Corn Syrup) on your long term health.

As America, with the rest of the world at it's heels, is suffering an obesity epidemic, your focus is on the wrong place.

It seems to me that "everyone" overlooks Energy Content differential.Gas(petrol) has better milage per Gal(Ltr).

True, but...
...diesel engines with their much higher compression ratios are far more efficient in converting that heat to mechanical energy.

My sweet Diesel-powered Volvo
Back in 1982, when I needed to buy a car, there were just four makes of diesel-powered station wagons, and the Oldsmobile was already being called "The Car That Falls Apart." I bought a Volvo 245GL, and I'm still driving it. I still prefer it over anything else on the road.

A couple of years after I bought it, California passed a law that required all new diesel cars be as clean as the Mercedes, which used a patented clean-diesel technology that they refused to license to other makers. The result was an immediate closure of three independent efforts to make diesel cars cleaner. That law exempted trucks, buses, and all government-owned vehicles, so the market for aftermarket clean-up devices dried up, and California is such a huge market that the diesel-car market dried up across the USA.

We all had to wait until the Daimler-Benz patented clean-diesel technology ran through its twenty years of patent protection. The next time you're behind a smoking diesel vehicle, "thank" the California EPA for making it smoky.

BMW/Honda/Peugeot/Toyota/Nissan/GM Europe/Ford Europe/Fiat allready have
All the above have (with the exception of Honda) have been doing diesel for decades and already have their own clean diesel and particulate filter tech - you don't need to wait for Mercedes.

Diesel hybrid
I'm surprised no one has offered a diesel hybrid yet. Seems like a diesel engine would be ideal for running a generator.

Indeed...
...especially considering that diesels are even more highly efficient when running withing a relatively narrow band of RPM. One of the challenges for passenger auto diesels has been getting decent performance across a wide band of RPM as drivers come to expect from gasoline engines.

Since both hybrid technology and diesel engines are more expensive than their traditional counterparts, my guess is that the marketplace isn't yet ready for it yet. My guess is that will change once the new fuel economy mandates distort the marketplace enough to eliminate cheaper competition.

This is a myth
"One of the challenges for passenger auto diesels has been getting decent performance across a wide band of RPM "

This is a myth. Drivers in Europe have been enjoying the benefits of Turbo-Diesel's for decades.

More economical, more power, far greater torque.

Peugeot
French Peugeot do one,.

They have also taken a novel approach to this, and instead of the electric part of the hybrid augmenting the front drive wheels, the electric motors drive the rear wheels, giving a pseudo-4x4 effect.
