Why almost a third of new-car shoppers are considering diesel

Consumer Reports News: June 11, 2013 09:08 AM

Among consumers likely to purchase a vehicle in the next two years, 31 percent are likely to consider a diesel, motivated by fuel economy and environmental concerns. This tidbit is among the findings of a recent survey conducted by the National Association for Convenience and Fuel Retailing (NACS).

To better understand consumers, NACS conducted an online survey last month of almost 1,200 Americans who buy gasoline. (Read the related report: "Ethanol doesn't spark interest among consumers.")

These diesel-curious shoppers will find an increasing number of vehicles to choose from, including the well-established Volkswagen Jetta and Passat, luxury SUVs like the BMW X5 and Mercedes-Benz GLK250, and the new Chevrolet Cruze. And there are many more diesels coming to market soon.

We have found that diesel models can provide exceptional fuel economy, although the powertrain often carries an added expense and the fuel prices tend to be higher than regular gasoline. Right now, diesel averages about 22 cents more per gallon, although its fuel economy benefits are generally much greater than the price premium. (See the latest national gasoline prices by region.)

Other answers strike us as curious, such as being better for the environment. While a diesel car may burn less petroleum, the smog-forming emissions are typically greater than with a contemporary gas-fueled car.

Likewise, the reliability perception born from past performance may no longer be so distinct. In our reliability surveys, we have not seen an appreciable difference with most models offered with gas and diesel powertrains where we have adequate data.

As surveys often point to, it is important for car shoppers to not base their selection strictly on perception. Check the data--readily available at for all major models--before buying.
