Study Indicates Diesel Interest Waining, But Other Options Still Needed
While most automotive manufacturers have shifted production to focus on smaller vehicles, nearly 70 percent of consumers say they want manufacturers to invest more in existing and emerging powertrain technologies, according to the J.D. Power and Associates 2008 Alternative Powertrain StudySM released today.

Now in its third year, the Alternative Powertrain Study examines the reasons why consumers consider or avoid alternative powertrain vehicles, such as hybrid, flex fuel and clean diesel fuel models. The study includes the Automotive Environmental Index, which combines U.S. Environmental Protection Agency (EPA) publicly available information related to fuel economy, air pollution and greenhouse gases for 2008 model-year vehicles and J.D. Power and Associates’ voice of the customer data related to stated fuel economy. Feedback from verified vehicle owners is also used to help determine the relative importance of these environmental factors.

The study finds that more than 80 percent of consumers believe that the United States is currently faced with an energy crisis. Only 18 percent of these consumers believe this issue can be addressed by focusing on small vehicle production with better fuel economy. Approximately 30 percent of consumers believe that auto manufacturers should continue to produce a comparable vehicle lineup with a focus on hybrid-electric, clean diesel and flexible fuel vehicles, while an additional 39 percent believe manufacturers should focus on developing emerging technologies not currently available in the market, such as fuel cell and electric vehicles.

“Nearly 80 percent of consumers believe that gas prices will continue to rise, which will have a significant effect on the vehicles they will consider,” said Mike Marshall, director of automotive emerging technologies at J.D. Power and Associates. “However, some consumers still want more than small cars to choose from in the auto market. They still want their SUVs and pickup trucks, except with better fuel economy and more environmentally friendly.”

The study also finds that the percentage of consumers who are considering a hybrid-electric vehicle is up from 50 percent in 2007 to 62 percent in 2008. Consideration for flexible fuel (E85) capable vehicles—which are designed to run on gasoline or a blend of up to 85 percent ethanol—has decreased slightly from 2007 (47% vs. 43% in 2008), while consideration for clean diesel demonstrated the most notable decline from 23 percent in 2007 to only 16 percent in 2008. The drop in consideration for diesel technology may be attributed to the substantial increase in the relative price of diesel since 2007.

Among the top 30 models in the Automotive Environmental Index, Toyota has the highest number of vehicles (6), followed by Chevrolet, Honda and Nissan with three models each. Additionally, eight models in the Automotive Environmental Index top 30 are hybrid-electric vehicles. They are:

Ford Escape Hybrid   
Nissan Altima Hybrid
Honda Civic Hybrid   
Toyota Camry Hybrid
Lexus RX 400h   
Toyota Highlander Hybrid
Mercury Mariner Hybrid   
Toyota Prius

The remaining models in the Top 30 Automotive Environmental Index are:

Chevrolet Aveo   
Hyundai Accent   
Nissan Sentra   
Smart Fortwo Coupe
Chevrolet Aveo5   
Hyundai Elantra   
Nissan Versa   
Toyota Corolla
Chevrolet Cobalt   
Kia Rio   
Pontiac G5   
Toyota Matrix
Ford Focus   
Kia Spectra   
Pontiac Vibe   
Toyota Yaris
Honda Civic   
MINI Cooper   
Saturn Astra   
Honda Fit   
MINI Cooper S   
Smart Fortwo Convertible

“It’s also interesting to note that among hybrid vehicles included in the top 30, all but one model receives a consumer-reported miles per gallon rating that is lower than the stated EPA rating,” said Marshall. “However, for the 2008 model year, the EPA has implemented a new methodology for estimating mpg, which has resulted in much smaller variances from consumer-reported fuel economy than seen in previous years.”

The 2008 Alternative Powertrain Study includes responses from more than 4,000 consumers who plan to purchase a new vehicle within the next two years. The web-based study was fielded in May and June 2008. The voice of the customer components of the Automotive Environmental Index are derived from the 2008 Alternative Powertrain Study and the J.D. Power and Associates 2008 Initial Quality StudySM.

Diesels are just not clean enough and their performance isn't anything special when compared to hybrids. I can see why people are beginning to see through the hype and lies about diesels.

Gee MichaelTaylor, while we're on the subject of lies, a V8 bi/twin turbo diesel would do something the LS600h never did -- actually accomplish the stated goals of gas V12 performance and gas V6/V8 fuel economy.

But that's ok. Not everyone has to actually live up their promises and marketing hype. Not when you have idiot fanboys who blindly suck off the Lexus marketing teat.

The Lexus LS600h set out what Lexus promised: amazing performance and low emissions. It's the cleanest car in its class and it only lags behind the S600 in performance.

Do not buy a diesel after 2006. 2007+ is subjected to the USLD regulation and you risk damaging the engine using anything other than ULSD(that's not to say you'll damage anything).

2006 and prior, you can put just about anything in the tank. That doesn't mean go buy a Jeep or Mercedes diesel because I'm pretty sure they're strictly ULSD.

Now that I think about it, I'm pretty sure Jeep and Mercedes didn't start importing the "new to us" diesels until 2007.

Forgot to add that ULSD has a lower energy content than regular diesel, so you're going to get fewer mpgs out of it compared to regular diesel. Thus the clean diesels will get fewer mpgs than their European equivalent.


AudiphileAudiphile - 7/15/2008 10:04:25 PM
+1 BoostDrop the Boost Up the Boost
I'm not so sure about that, BMW8er. European diesel fuel has a much lower sulphur content than traditional non-ULSD fuel, thus the Euros' diesel is pretty close (if not identical) to our ULSD in terms of energy efficiency. You could be right, though.

You don't have to look very far to see why diesel interests are waning. Just compare diesel fuel prices to regular and premium fuel and you will see diesel is 20% and 10% higher.

MichaelTaylor. You're ignorant to 40 years of technological advances in diesel engine technology, so stop commenting. You come across poorly.

yes, diesel is 10% more than premium fuel. But if it gets 35%+ better fuel economy than the gas car, it's a net gain of 25+%. A hybrid basically get you that same 25% bump, but instead of paying $3000 more for the car versus the gas version (like the diesel) you have to pay $8-33k more.

So which one saves you more money? Hint: you have a 50-50 chance, and it's not the hybrid.

Hybrid = ok. Diesel = better. Diesel hybrid = now we're talking...

I agree! Diesel hybrid would be a win-win combination!
Can't wait for the first diesel-hybrids to arrive in the future.

yes what on earth is wrong with them? This was obviously the best option from the very beginning! Add a cvt gearbox and I am willing to bet a VERY low fuel consumption figure could be reached!

You're right about the current high cost of diesel fuel damping some of the demand for clean diesel engines. However, I noticed in an earlier entry that many VW dealers have already met their annual allocation of the new Jetta TDI, even though the car won't go on sale for another month!

Granted, the Prius has higher EPA ratings, but the Jetta performs better, and the Jetta might be a roomier, better-finished car. (I can't be certain about that last point.)

I have also noticed in my area that the gap between diesel and gasoline is slowly going down. Chevron & Shell dealers now sell diesel for only $0.41 per gallon more than premium, while only about a month ago the gap was $0.50 per gallon.

Finally, some of my mechanic buddies tell me that diesels have an easier time than hybrids of achieving their EPA mileage in real-world driving situations. I'm tempted to buy a diesel-powered car when my lease expires.

MichaelT's biases are so transparent it's embarrassing. No fuel solution is perfect, whether hybrid or diesel, but to compare diesel with a gas-hybrid is silly. What you need to compare is a diesel-hybrid with a gas-hybrid, now we're talking. Unfortunately, until a diesel-hybrid alternative exists, the "best" comparo is with a regular diesel, and yet, even with that disadvantage, the diesel is the more efficient solution than the hybrid. Sorry Prius, but there is no way you can compare to a similarly weak diesel engine in terms of fuel efficiency (hint, only Europe gets these mini-diesel engines).

It's all about fuel prices.

Back when diesel was the same or less than gasoline it made a great deal of sense. That day may very well come again. Who knows.

At the end of the day, diesels are more fuel efficient, last longer and don't pollute any more than gas.

If you're cold starting a diesel in the winter and then not driving it long enough to warmup, you're doing more damage to the diesel engine than you would be to a petrol engine.

In case you weren't aware, M-B will have that diesel hybrid in 18 months or less:

http://www.nytimes.com/2008/01/15/automobiles/autoshow/14-s300.html

Concerning gas and diesel prices, I've observed something quite interesting in my area of the Midwest. Regular gas has fluctuated +/- $0.35 in prices over the past 10 weeks. It's $4.20/gallon as of July 15th, but has been as low as $3.98/gallon over the past 3-4 weeks. In the same 10 week time frame, diesel prices have only fluctuated +/- $0.15 and has been stuck at $4.79/gallon for about 3-4 weeks.

To complicate matters further, the European Commission is investigating the U.S. over dumping subsidized biodiesel in their markets. It gives the appearance that not only is the U.S. artificially altering the price of biodiesel abroad, but at home as well.

http://news.bbc.co.uk/2/hi/business/7453564.stm

Now this is only my opinion, but wouldn't you think diesel prices in the U.S. would be more in line with gas prices if this wasn't happening?

Add in the fact that the U.S. Justice Dept. has been given the "ok" to sue OPEC, along with the lifting of the executive order banning off-shore drilling (political grandstanding?), and consumers don't take the time to factor their cost per mile, I would think that there just isn't a right or wrong answer for consumers right now when it comes to what fuel is used or the engines powering their vehicles.

Interest in diesels is waining because most people still don't have ANY experience with them. You might as well ask most Americans just how interested they are in buying a seaweed powered car. That all said... all this 'diesel waining' sure doesn't seem to be behind the tremendous INTEREST in the 2009 VW TDI's now - does it. Craig!! :o)

Lately, I've been obsessing over hydrogen. Everyone knows about the BMW's hydrogen 7, but what about making it main-stream. We have the ability people! There is a private taxi company in my city that fuels exclusively with hydrogen. They have 30 gallon aux tanks in the trunk and a hydrogen conversion system running along the drive shaft and on either side of the engine. Now, I understand that the prominent concern is refueling, but it isn't that difficult! In addition to having your own compressor ($3500), there are already about 2000 stations around the country. While this technology makes me smile every time I think about it, it's still dangerous as all hell.
America's problem is that we're took scatter brained! It takes an amazing amount of capital to make a technology feasible.
For instance, when we made the mistake of developing e85, it was government subsidized with full backing from General Motors. After well over a billion dollars in research, they finally built a fleet of cars capable of running on something other than that black gold! One thing, though, is that we used a resource that was already in major demand. Corn, soy beans, etc. are all necessities for a functioning society!
When I first read about this new ethanol technology, I was thrilled because I thought we might finally see extraordinarily cheap gas...then I finished the article. I'm guessing these developers never considered the law of supply and demand. When the demand for corn is 93.8% of the supply, that means that if you increase demand, the price is going to rise due to a lower supply. (Horribly complicated, I know) This drives me crazy because it's like they were just asking for rising food costs and overall inflation to take place!!!!
There's no question that we need other/better options, but use a little damn common sense. Get out of those physics and chemistry classes and drop in on a few economics courses. There are a lot of unutilized resources out there just waiting for us to exploit, why are we still wasting time with the normal stuff!

Sarcastic,
The hydrogen7 gets 4mpg.

The longer the Germans stay with 19th century technology, the further ahead everyone else will become.

Btw, the 2008 EPA standards actually show diesels have a larger drop than hybrids.
