Diesel engines are increasingly popular among automakers, drivers

Drivers in the U.S. are discovering what Europeans have known for years: Diesel engines are powerful and still get eye-popping fuel economy, especially at highway speeds.
Diesels account for just 3 percent of U.S. auto sales. But automakers see that increasing as they offer more diesel models, part of the effort to meet increasingly stringent federal fuel economy standards.
GM joins Volkswagen, Audi, Mercedes-Benz and BMW in pitching diesel passenger cars for the U.S. market. This year, Jeep will offer a diesel version of its popular Grand Cherokee sport utility vehicle, and Mazda Motor Corp. will offer a diesel version of the new-generation Mazda6 sedan.
The automakers are using versions of diesel engines they have already developed for Europe and other markets.
Diesels now account for about 20 percent of VW’s sales volume in the U.S. The company welcomes the entrance of new diesel competitors, believing a rising tide will lift all boats.
“This is not a fixed slice of pie that gets divided by the same customers,” said Jonathan Browning, chief executive of Volkswagen Group of America. “This will grow the diesel segment, and that’s good news for us.”
Automakers hope to lure more buyers such as Danny Albarran, a Simi Valley, Calif., resident who drives a diesel Dodge Ram pickup truck. The Los Angeles City Fire Department engineer learned to appreciate diesels after seeing their reliability and efficiency while driving firetrucks.
“You will see diesel trucks and cars out there regularly get 200,000 to 300,000-plus miles,” said Albarran, who also owns a Toyota Prius. “We rarely have true engine trouble with our firetrucks — none of the issues you see with gasoline engines.”
Even in everyday vehicles, diesel engines provide more power, better fuel economy, a higher resale value and extra longevity, he said.
The resale value of a compact car with a diesel engine is about 63 percent of its sticker price after three years, according to ALG, a consulting firm that estimates used car values for the leasing business. That compares with 53 percent for a compact car with a gasoline engine.
But there are drawbacks.
Consumers pay a premium for that diesel engine — from about $2,000 for a VW hatchback or sedan to more than $5,000 for a luxury car or big truck.
Although the fuel economy for a diesel can be as much as a third better than for a gasoline car, oil companies charge more for diesel. Depending on what’s happening in the oil industry, the gap has been as much as 50 cents a gallon over regular-grade gasoline in the last year or so. Diesel has been 20 cents to 30 cents higher for much of the past two years, according to the nonprofit Diesel Technology Forum.
Currently, diesel costs 45 cents, or about 13 percent, more than regular-grade gasoline, according to the AAA Fuel Gauge Report. About half of all service stations nationwide have at least one diesel fuel pump.
Part of the gap comes from taxes. Federal taxes on diesel fuel are 6 cents a gallon higher than for gasoline, a result of an agreement with the diesel-dependent trucking industry as a way to make up for the extra wear and tear heavy trucks put on the nation’s roads.
A growing number of consumers appear willing to accept that extra fuel expense, perhaps inured by the high price of all automotive fuel, said Allen Schaeffer, executive director of Diesel Technology Forum. Sales of diesel vehicles have risen by double digits in 20 of the last 24 months, he said.
Car buyers “are looking at long-term value,” Schaeffer said.
Americans have historically shunned diesels. That’s because of historically cheap gasoline, compared with other countries, and because the first diesel passenger cars were noisy, smoky, smelly and slow.
“Just recently are we seeing that image begin to change,” said Tom Libby, an analyst with automotive research firm R.L. Polk & Co.
Rainer Michel, vice president of product strategy for Volkswagen, remembered diesels in the 1970s usually getting passed by other cars as their rattling engines spewed “black smoke like crazy.”
“The only passenger cars you’d see were the Mercedes, and they were really dogs,” he said.
The addition of turbochargers and other technological advancements solved those problems, making many modern diesels as quiet and powerful as gasoline engines.
“I think diesels have not had a fair shake in America,” said Jake Fisher, automotive test director for Consumer Reports. “The small displacement turbo diesels of the type that VW is doing are very good and have great fuel efficiency.”
Consumer Reports recently tested a VW Passat diesel and found that it achieved 51 miles per gallon while traveling 65 mph on the highway. “That’s amazing for a roomy, a full-size sedan,” he said.
Chevrolet has put VW in the cross hairs with the Cruze.
“We expect to compete head-to-head with the German diesels, in particular VW’s Jetta TDI,” said Gary Altman, chief engineer for Chevrolet’s small cars.
The new Cruze will have a 2.0 liter, four-cylinder engine that will get an estimated 42 mpg in highway driving with an automatic transmission. With a 15.6-gallon fuel tank, the diesel Cruze could have a range of as much as 650 miles between fill-ups.
The car is based on the model sold in Europe, where approximately 40 percent of Cruze sales have the diesel engine.
Altman said the Cruze will deliver an estimated 148 horsepower and 258 pound-feet of torque and go from zero to 60 mph in 8.6 seconds. Chevrolet plans a starting price of $25,695 when it goes on sale this year. That will include two years of maintenance.
The Cruze will be the first Chevrolet diesel car since the 1986 Chevette.
“The compact car market is huge,” said Cristi Landy, a Chevrolet marketing director. “We think there is some room here and some opportunity.”
