Hang onto your hats. The most fuel-efficient petroleum powered sedan in America for open road cruising is the 2017 Chevy Cruze Turbodiesel. While a number of hybrids may be more efficient in city driving, the Cruze turbodiesel delivers off-the-charts fuel economy out in the country and on the highway. I covered 336.3 miles in mixed conditions and used only 6.942 gallons of diesel fuel (verified via tank fill, not the onboard computer), with an overall average of 48.4 miles per gallon (MPG) in my six-speed manual tester.
2017 sets another high point for fuel efficiency with a bumper crop of hybrids, turbo-diesels, and small-displacement vehicles that will knock your socks off. Not only do these highly efficient cars deliver great gas mileage, many are exceptionally rewarding to drive and stylish to boot.
While the brand new Hyundai Ioniq swipes the top spot from the Toyota Prius, the Kia Niro, Honda Accord Hybrid, and Chevrolet Malibu Hybrid are roomy and packed with creature comforts.
Here’s our list of the Top Fifty Cars of 2017 with Great MPGs (without a plug) …
Fleet vehicles use a whopping amount of fuel. The Federal Highway Administration estimates that the average delivery truck travels approximately 13,000 miles per year, a police car slightly over 15,000 miles, and a light truck nearly 12,000 miles. Multiply those numbers by the size of each fleet and the numbers roll up.
Whether it’s a police cruiser, an appliance repair truck, or an executive transport coach, optimizing idle settings is key to slashing overall fleet fuel consumption. The average fleet vehicle spends a monumental amount of time idling. A fleet manager can see a substantial reduction in fuel costs by implementing some simple changes. Yet it’s rarely done.
I am a road-test editor by trade. Testing fuel-efficiency is a key part of my job. It seems odd that the EPA, NHTSA and CARB have teamed up on TAR, but that the DOE and USDA have been left out.
The Oak Ridge National Labs work on this topic is crucial. The world’s largest automobile manufacturers are all turning to highly-efficient downsized, down-speeded small displacement forced-induction engines. They produce more power with less weight.
Modern forced induction small-displacement engines LOVE high-octane low-carbon fuel. The most cost-effective way to achieve high-octane is with ethanol.
I have begun fuel efficiency testing with E15 fuel. My first E10 vs E15 test with a turbocharged 1.4-liter 2017 Hyundai Elantra Eco produced remarkable results:
I hailed an Uber when I was in Charlotte a while back. When the car arrived, I was surprised to see that it was a Dodge Caravan. The Uber driver explained that he bought his Caravan because Minivans are eligible for UberXL which can generate more revenue. He also wanted to provide the most comfortable and convenient ride for his customers.
Some Uber drivers will tell you that the Toyota Prius is the best car to use. But that’s largely because it’s so good on gas, not because it’s the best ride for their customers.
The Dodge Caravan and the new Chrysler Pacifica are Flex Fuel vehicles. They can run ethanol blends up to E85. Ethanol burns cleaner and is 100% domestic. Department of Energy (DOE) Research says an E30 blend – 30 percent ethanol – may deliver the optimal price/performance ratio.
