Most Americans Don’t Care How Fuel Economy is Achieved, Says Study

Although nearly all American drivers are at least somewhat concerned about fuel economy, a majority don't care how a vehicle saves fuel – just that it does, say University of Michigan researchers.

In a new survey of 674 vehicle owners across the U.S., Brandon Schoettle and Michael Sivak of the U-M Transportation Research Institute examined several topics related to fuel economy and advanced vehicle technologies (continuously variable transmissions, cylinder deactivation, diesel engines, gasoline-hybrid vehicles, stop-start engine systems, supercharging, turbocharging, twincharging).

According to the report, a little more than half (52%) of respondents said it didn't matter to them how a vehicle saves fuel and reduces emissions. However, 24% listed engine improvements and 20% cited alternative fuels as their preference for improving fuel economy.

The report says men and drivers over 45 were more likely to favor engine improvements, while younger motorists preferred alternative fuel sources (diesel, electric, hydrogen) as the primary means to save fuel and reduce emissions.

About 73% of those surveyed said they would be less likely to own or lease a vehicle that requires more expensive premium fuel, the report adds.

‘Overall, fuel economy is important to consumers, and they generally do not care specifically how fuel savings can be achieved,’ says Schoettle. ‘Knowledge and opinions were mixed, with older respondents and males being more likely to have stronger opinions – both positive and negative – and to claim to know more about the technologies covered by the survey than younger respondents and females.’

The report says that although about 90% of respondents indicated that they basically understand how diesel engines and gasoline-hybrid vehicles work, a majority also said they had never heard of twincharging, cylinder deactivation or continuously variable transmissions.

Regardless of knowledge, a majority said they felt very or somewhat positive about advanced vehicle technologies, with the exception of continuously variable transmissions. In addition, the report says stop-start engine systems received the most negative ratings, although more than 60% of respondents viewed them as at least somewhat positive.

The U-M survey also asked vehicle owners which advanced technology they would prefer at two different gasoline price points: $2.50/gallon and $5/gallon. The report says that at both prices, gasoline-hybrid vehicles were the most preferred technology, while twincharging was the least.

Among powertrains, gasoline hybrids ranked first at either price point, while diesel internal-combustion engines were the least preferred. Gasoline internal-combustion engines rated second-most preferred at $2.50/gallon, ahead of electric vehicles, plug-in hybrids and hydrogen fuel-cell vehicles – but below them at the higher price point.

Finally, Schoettle and Sivak asked respondents about their willingness to pay for improved fuel economy. The results indicate that 25% would be willing to pay at least $300 for a 5% improvement in fuel economy, $1,000 for a 10% improvement and $2,500 for a 25% improvement.
