Washington, D.C. – New orders of clean diesel and diesel-electric hybrid buses by transit agencies in major communities like San Francisco, Chicago, Detroit, and New York over the past year are a strong indication that clean diesel technology is still the all-around best choice for public transportation according to Allen Schaeffer, the Executive Director of the Diesel Technology Forum.
Diesel vehicles use a more energy-dense fuel and a different combustion cycle than a gasoline engine that, together, lead to improved fuel efficiency. New advances in pollution-control methods have made the pollution from diesel vehicles comparable with gasoline vehicles, and many manufacturers are now deploying diesel vehicles to reduce fuel use.
I would have liked to sample the Diesel Cruze for a year to see if I could top the highway mpg score of my own Cruze, which was 50.2 mpg over 50 miles. The Cruze Diesel did the same 50 miles at 58.6 mpg and I didn’t even try like I had to with my Cruze Eco. Over the entire week and 454 miles, I averaged 44.1 mpg with a bit more highway than city driving. The sticker says 27 mpg city and 46 mpg highway, and 33 combined, so it was easy to beat what the sticker says.
We're proud of the role diesel equipment plays in America's emergency response programs. From powering the backup generators that give hospitals and operating rooms electricity within 10 seconds of a blackout to powering disaster-relief vehicles, diesel is a key player in protecting our public health and safety.
Washington, D.C. – A new study published today said that switching from diesel to natural gas in heavy-duty trucks could worsen and accelerate negative climate impacts unless methane leakage can be lowered. The study also outlined the need for increased data and new policies to lower methane leakage in order for natural gas heavy duty trucks to have a possible environmental advantage over new and future clean diesel trucks.
