Car fuel efficiency is increasing every year
New vehicles being launched in the past four years have a higher degree of fuel efficiency. This fuel efficiency is up 14% according to a study conducted by the University of Michigan. Consumers are showing increased awareness where fuel efficient vehicles are concerned and this is what has led auto companies to concentrate on this aspect while designing their vehicles.
From the year 2008 to 2012 car fuel efficiency has increased by 2.8 miles per gallon while light trucks and SUVs have seen an increase by 1.6 miles per gallon. Maximum increase has been seen in station wagons where fuel efficiency has increased by 4.1 miles per gallon in the past four years which has resulted in all station wagons offering a maximum average of 26 miles per gallon as on date.
With rising prices of fuel in the past years, customers are on the lookout for vehicles offering a higher level of fuel efficiency which has prompted auto companies to cater to these increased demands.
Fuel economy of new vehicles continues to rise
ANN ARBOR, Mich.-The average fuel economy of current model year vehicles is 14 percent higher than just four years ago, say researchers at the University of Michigan.
For all 2012 light-duty vehicles (cars, pickup trucks, minivans, vans and SUVs) offered for sale, average mpg is 21.5, compared to 18.9 mpg for model year 2008 vehicles. The averages were 21.2 for 2011, 20.7 for 2010 and 19 for 2009.
For new vehicles actually purchased, average fuel economy is typically one-to-two miles per gallon higher-22.5 mpg for model year 2011 (the last full year of sales), 22.1 for 2010, 21.3 for 2009 and 20.8 for 2008.
“This implies that consumers tend to choose vehicle models with better fuel economy than the average of all vehicles available,” said Brandon Schoettle of the U-M Transportation Research Institute. “The recent economic downturn, coupled with rising gas prices, has led to an increased interest in purchasing more fuel-efficient vehicles.”
Using data from the EPA, Schoettle and UMTRI colleague Michael Sivak also examined fuel economy changes by vehicle characteristics: cars vs. light trucks, vehicle class size, transmission type, number of engine cylinders, drive type, fuel type and hybrid vs. conventional vehicles.
They found that average fuel economy:
Improved 2.8 mpg for cars (including station wagons) and 1.6 mpg for light trucks (pickups, minivans, vans and SUVs) from model year 2008 to model year 2012. Average fuel economy is currently 23.4 mpg for cars and 18.6 mpg for light trucks.
Increased for all 12 vehicle-size classes between the 2008 and 2012 model years. The largest increases were 4.1 mpg for station wagons, which had the highest average 2012 rating of 26 mpg, and 3.8 mpg for compact cars, which had the second-highest average of 25.6 mpg. The smallest increases were 0.2 mpg for full-size vans, which had the lowest average 2012 rating of 13.4 mpg, and 0.4 mpg for small pickup trucks, which had the third-lowest average of 18.6 mpg.
Increased 2.5 mpg for vehicles with automatic transmissions and 2.8 mpg for vehicles with manual transmissions; 2.3 mpg for four-cylinder engines and 1.4 mpg for six-cylinder engines; and 3.4 mpg for front-wheel drive vehicles and 2 mpg for four- or all-wheel drive vehicles from model year 2008 to model year 2012.
Improved 9.8 mpg for diesel engines and 2.6 mpg for conventional gasoline engines, but dropped 3 mpg for hybrids, which are still more fuel-efficient overall than internal-combustion-only vehicles.
