Hyundai Considering Diesel for the US

Hyundai may offer diesel engines across its US lineup of cars and trucks as an alternative to gasoline-electric hybrids if it can clear cost and technical hurdles, according to a report in the Detroit Free Press.

Steve Wilhite, chief operating officer of Hyundai Motor America, told the paper that diesels made better financial sense than hybrids, although Hyundai has hybrids under development.

“The highest priority on my personal wish list is bringing our diesel technology to the United States, and I’d like to bring that across all of our products,” Wilhite said in an interview at the New York auto show. “It just seems like a much more elegant solution to me than a hybrid.”

Some of that diesel technology was on display at the 2007 Seoul Motor Show. While the main focus of the Seoul show was three new vehicles—the Veloster sports coupe concept, the production TQ van, and the production FD estate wagon—Hyundai also had on display:

  • A Urea-SCR (Selective Catalytic Reduction) emission treatment system applied on the 3.0-liter S-Engine installed on the Veracruz.

  • A NOx and particulate matter treatment system which is capable of meeting the upcoming Euro-6 emission regulations—and which thus might also be able to meet Tier 2 Bin 5 regulations in the US.

Also on display was a Sonata LPI (Liquefied Petroleum Injection) Hybrid Electric Vehicle and a Tucson Fuel Cell Electric Vehicle.



Awesome! Bring it on Hyundai! Thank you for not trying to exploit the E85 loophole to meet fuel efficiency standards, and not completely jumping on the gasoline-electric hype-brid bandwagon.

The fact that Hyundai recognizes diesel's real-world benefits over gasoline-electric hype-brids speaks volumes to their company's leadership. I might just have to buy some Hyundai stock.

Having consistently achieved ~50mpg driving numerous clean-diesels from Ford (Mondeo, Focus Wagon), Opel (Astra), VW(Golf), Fiat(Multipla), and MB(E220CDI) over my years overseas I can personally attest that they are superior to the current crop of hybrids. During my relatively short drives in a Prius, and Camry Hybrid I was only able to achieve ~42mpg and ~33mpg respectively.

Add to their superior real-world fuel economy the fact that clean-diesels can be fueled with biodiesel from numerous renewable sources- and the US can start moving towards energy independence!

Hyundai- I applaud your efforts! GM, Ford, & Chrysler: take a good hard look at the car companies that are showing explosive growth in the US and learn! You'll keep eroding your market share if you continue to fight what the market demands.


Hey DH,

I agree with you 100%!!!

It's either fulL BEV or high efficiecy diesel...it's a matter of fact that we do not need gasoline engines at all...diesel car running on B100 would do just fine!

Although, BEVs are also a great option!



I dont know bout the "matter of fact" but I certainly do welcome the competition to phev, bev,E85.A choice between clean diesel and serial hybrids could blow cafe stsndards away.I would like a basket of technologies going forwad rather than tunnel vision focused on one{hydrogen}tech answer.


Overseas is in your case Europe. But there are no clean Diesels. So, where have you been and want have you been driving?

Please, look at the EURO IV and coming EURO V emission regulation and compare the Diesels and patrol emissions. And please, take into account that the patrol engine are far below the regulation. Not the Diesels.

As a rule of thumb, a Diesel produces 10 times more harmful emissions than a petrol car. In got cases is around 8 times.
Please, think about it.



A diesel does not produce 10 times more harmful emissions than a petrol car; in fact, diesels produce less.

Check your assertions. A diesel produces much less harmful emissions by weight than a gasoline/petrol powered car per mile driven.

Diesels do produce more NOx and particulate than gasoline/petrol but they produce much less greenhouse gas (carbon monoxide and hydro-carbons) which is the primary exhaust emission by weight. NOx and particulate are now being addressed in new diesel technologies.

In addition, new studies show that gasoline engines when under load match or exceed particulate emissions of diesel engines (Univ Michigan) and that gasoline produced PM are more toxic than diesel produced PM.

Gasoline engines also have a higher ramp-up of emissions as the engine ages compared to diesel engines.

Now, with Bio-diesel introduction, things are even better for diesels. Bio-diesel results in an additional 25%+ reduction in Carbon Monoxide emissions over petrol based diesel.

New evidence shows that diesels are also better than petrol/gasoline for fighting ground level ozone. Studies were done because of the confusing fact that in SOCAL ground level ozone was consistently higher on weekends than weekdays - it was confusing because more cars and less diesel trucks were on the roads on weekends.

QUOTE: 'The reason, according to Whitten, is that a reduction in hydrocarbon and carbon monoxide emissions has a much greater beneficial impact on ozone formation than an equivalent reduction in NOx. Whitten concludes, "The effectiveness of THC for reducing ozone in these simulations must be as much as 8 times better than NOx reductions on an equal percentage of the mobile emissions basis." Since diesel engines tend to have significantly lower emissions of CO and HC (VOCs), while generally higher emissions of NOx, one could conclude based on these recent studies that an increasing market share of diesel-powered cars and light trucks will have a positive impact on ground level ozone rather that the negative impact which has always been assumed. '

This fact that CO and HC are larger contributors to ground level ozone was also backed up by a National Research Council's (NRC's) study.
