Ward’s Auto presented its list of the “10 Best Engines” for 2010. The list includes powertrains that are high-mpg in their efficiency, but are power performers.
Although fuel economy isn’t technically one of the criteria, 40mpg.org, a public interest group, notes that going green for your next car doesn’t necessarily mean you need to sacrifice performance. … You can keep the power you crave and save at the pump, the organization remarks.
Two hybrids, two clean diesels, and three 4-cylinder engines made the list. Volkswagen and its luxury line, Audi, did particularly well with three engines on the list. Also notable, was only one V8 made the list, whereas as many as four made the list in 1997 and 1999.
Those engines for 2010 and their vehicles are:
- 2.0L TFSI Turbocharged DOHC I-4 (Audi A4)
- 3.0L TFSI Supercharged DOHC V-6 (Audi S4)
- 3.0L DOHC I-6 Turbodiesel (BMW 335d)
- 2.5L DOHC I-4 Hybrid (Ford Fusion Hybrid)

Although heavy-duty vehicles have been exempt from fuel economy regulations, the new EPA finding that greenhouse gas emissions are dangerous to human health may change that.Mpg for medium-duty trucks had risen in some recent research but based on the number of these trucks on the road, how much gas they consume due to very low mpg, and the number of miles they drive, fuel economy improvement in this sector is needed as part of the larger vehicle strategy for the United States.A counsel for the American Trucking Association says it is possible a fuel economy rule for heavy trucking could be enacted as soon as 2016.
ACEEE has said average fuel economy for heavy-duty vehicles could be increased by over 50% in the next 10-15 years.Gains in this sector can make a big impact to improve the environment and reduce U.S. dependence on oil.
