Car manufacturers have revealed the specs on their 2018's. As expected, they are a little more fuel efficient than the 2017 models. The most efficient cars are being produced by the manufacturer's that usually make the greenest cars. Although there are a couple surprises. Whether you're looking for a more fuel-efficient gas-powered sedan or hybrid SUV, we've got the numbers for you. As your shopping, keep in mind that you can get a sizeable income tax deduction for buying a plug-in hybrid or electric car.
Which 2018 gas-engine cars are the most fuel efficient?
Toyota is leading the way in gas-powered fuel-efficient cars for 2018. The Toyota Prius gets the best mileage. It gets 48 mpg in the city and 43 mpg on the highway with a 1.5-L 4-cylinder gas engine. The new Camry gets 29 mpg in the city and 41 mpg on the highway. It has a 2.5-L 4-cylinder engine with an automatic transmission.
The Mitsubishi Mirage gets 33-37 mpg in the city and 40-43 mpg on the highway.
Chevrolet is giving Toyota and Mitsubishi some serious competition, though. The 2018 Cruze gets 27-29 mpg in the city and 37-40 mpg on the highway with its 1.4-L 4-cylinder engine. The diesel-powered Cruzes get 29-31 mpg in the city and 45-52 mpg on the highway.
Honda's 2018 Fit gets 29-33 mpg in the city and 36-40 mpg on the highway. The Civic gets 22-32 mpg in the city and 36-42mpg on the highway, depending on which model you get.
Which 2018 luxury cars are the most fuel efficient?
Lexus is blowing away the competition with the ES 300h. If you get the 2.5-L 4-cylinder automatic trim, you can expect to get 40 mpg in the city and 39 mpg on the highway. The GS 450h gets 29 mpg in the city and 34 mpg on the highway. The LC 500h with a 3.5-L 6-cylinder automatic trim level gets 26 mpg in the city and 35 mpg on the highway.
BMW is making their luxury vehicles greener, too. The BMW 230i, 330i and 320i, 430i and 530i get 24 mpg in the city and 34-35 mpg on the highway. BMW 328d diesel-powered models get 30-31 mpg in the city and 40-43 mpg on the highway.
The Porsche Panamera 4 E-Hybrid is causing quite a stir and Porsche is letting the suspense build. At this time, we don't have the mileage figures on this one, but they are rumored to be impressive.
What are the most fuel-efficient hybrids?
The Chevrolet Volt hybrid is the most fuel-efficient hybrid with 106 mpge combined and 42 mpg combined with the gas-powered engine. However, there are still a couple of contenders that we don't have the numbers on yet.
The 2017 BMW i3 was the most fuel-efficient hybrid with a combined mpge of 124. BMW hasn't released the specs on the 2018 i3s but, if they are at least as good as the 2017 i3, they will be the most fuel-efficient hybrids in 2018. Oh, and, that is "s" as in plural. BMW has expanded the hybrid family.
What are the most fuel-efficient 2018 SUV's?
Lexus is bringing the green in the SUV category this year, too. The NX 300h AWD SUV hybrid gets 33 mpg in the city and 30 mpg on the highway. Toyota's RAV4 Hybrid AWD beats it by 1 mpg, though, with 34 mpg in the city and 30 mpg on the highway.
The Honda HR-V is classified as a station wagon; however, it's a sporty-looking gas-powered station wagon that is very fuel-efficient. It gets 25-28 mpg in the city and 31-34 mpg on the highway.
Which all-electric cars are the most efficient?
At this time, the 2018 Kia Soul Electric is at the top of the list with 124 mpge in the city and 93 mpge on the highway. However, we don't have all the numbers just yet. Last year's Hyundai Ioniq was the most efficient electric car. It gets 150 mpge in the city and 122 mpge on the highway and has a range of 124 miles per charge.
The 2017 Chevrolet Bolt EV hatchback and Volkswagen e-Golf might have them both beat, though. The Bolt EV gets 110 mpge on the highway and 128 mpge in the city and can go up to 238 miles on a fully-charged battery. The eGolf gets 126 mpge city and 111 mpge highway and has a range up to 125 miles on one charge. Chances are, Chevy and Volkswagen have made some adjustments, and the Bolt EV and e-Golf will be a little more fuel efficient. For now, we can only speculate.
