Fuel economy still shapes most car purchases, and the 2027 model year offers a wide spread between frugal hybrids and thirstier performance picks. These sedans, coupes and hatchbacks are mainstream regular-fuel models, and each carries an official combined rating. Here are twelve cars that show how far mileage and annual fuel cost can diverge.
1. Toyota Prius: Efficiency Benchmark
The fifth-generation hybrid carries an EPA-estimated rating of 55 mpg combined in the 2027 LE grade, which starts at $28,755. That figure leads every car on this list by a wide margin, and the low, sleek body is a large part of how the powertrain reaches it.
The rating is a few mpg below the 57 earned by the 2026 model, so buyers comparing model years should expect a small step back. Even so, the balance of price and mileage remains the strongest in the segment for commuters.
2. Hyundai Sonata Hybrid: Midsize Mileage Surprise
The 2027 Sonata Hybrid Blue posts a published fuel-economy listing of 51 mpg combined, split into 47 city and 56 highway, with annual fuel cost put at about $1,300. Highway mileage that exceeds city mileage is the signature of a hybrid system tuned for long, steady driving.
Few midsize sedans pair this much cabin room with such low running costs. Drivers who cover long commutes stand to save the most, since the highway number is the better of the two.
3. Toyota Corolla Hybrid: Compact Hybrid Staple
Toyota’s compact hybrid sedan earns an official mileage rating of 50 mpg combined for 2027, made up of 53 city and 46 highway, costing roughly $1,350 a year in fuel. Its city figure beats its highway one, the classic hybrid pattern in which regenerative braking recovers energy in stop-and-go traffic.
Urban commuters benefit most from that split, while drivers logging mostly interstate miles will see the number drift lower. The rating still ranks among the best available without plugging in.
4. Honda Prelude: Hybrid Coupe Returns
Honda’s revived two-door earns a combined-mpg estimate of 44 mpg combined for 2027, with fuel spending estimated at $1,500 a year. The nameplate returns as a hybrid coupe, trading the old high-revving image for efficiency that few sport-styled cars can match.
Shoppers drawn to coupe styling rarely get a fuel bill this modest, so the Prelude fills an unusual niche. Anyone expecting performance-car thirst should note that the rating sits much closer to a family hybrid than a sports car.
5. Toyota Corolla Hatchback: Practical Hatch Pick
The 2027 Corolla Hatchback manages a hatchback mileage listing of 35 mpg combined, made up of 32 city and 41 highway, at about $1,900 a year in fuel. The drop from the hybrid sedan higher on this list shows how much the electrified system contributes.
Buyers who want hatchback cargo flexibility without hybrid pricing still get respectable mileage. Highway trips deliver the best returns, while heavy city use pulls the average toward the low thirties.
6. Nissan Sentra: Budget Sedan Standard
Nissan’s compact sedan carries a combined mileage rating of 33 mpg combined for 2027, and the annual fuel estimate is $2,050. Pairing that mileage with a modest sticker has made the Sentra a staple for cost-conscious drivers who want no hybrid hardware to maintain.
The gap between its fuel bill and the 50-mpg Corolla Hybrid is roughly $700 a year, so the savings depend on how far the car is driven. Low-mileage owners will hardly notice the difference.
7. Mercedes-Benz CLA: Luxury Gas Sipper
The 2027 CLA 220 earns a CLA 220 rating of 33 mpg combined, matching far cheaper sedans, yet its annual fuel estimate climbs to $2,500. A gap that large suggests the premium-grade fuel typical of luxury cars is raising the cost of every gallon.
Luxury shoppers should read the mileage and the dollar figure together, since the same mpg costs several hundred dollars more each year than in an economy car. The efficiency is genuine, but it is not cheap to feed.
8. Kia K4: Value Sedan Contender
The 2027 K4 sedan with the driver monitoring system is rated at 33 mpg combined, with 29 city and 39 highway, and an estimated $2,050 a year in fuel, according to MPG Buddy’s K4 listing. That puts the K4 level with the Sentra and the CLA on the efficiency ladder.
A rating this strong in a roomy compact sedan keeps the K4 competitive against its best-known rivals. Mileage can vary by trim and equipment, so buyers should check the exact version on the window sticker before comparing, because the listing covers only one configuration.
9. Mini Cooper: Small Car, Modest Mileage
The 2027 MINI Cooper C 2 Door is rated at 31 mpg combined, with 27 city and 39 highway, and an estimated $2,650 a year in fuel figured on premium gasoline, per MPG Buddy’s Cooper C listing. Its turbocharged three-cylinder engine is tuned for lively driving rather than record-setting economy.
Owners who choose the Mini for personality should expect fuel costs closer to a midsize sedan than to the featherweight image. The charm is real, but frugality is not what the car is selling.
10. Kia K5: Stop-Start Midsize
The 2027 K5 equipped with stop-start is rated at a stop-start efficiency rating of 30 mpg combined, with 26 city and 37 highway, and fuel is priced at about $2,250 a year. Automatic engine shutoff at stoplights is meant to trim city consumption, yet the city number remains the weakest of its figures.
Highway-heavy drivers will see the best results, since the 37 mpg figure sits well above the combined rating. The K5 makes sense for buyers who prioritize space and style over the lowest fuel bill.
11. Subaru Impreza: All-Wheel-Drive Compromise
Subaru’s compact hatchback is rated at a combined fuel-economy figure of 29 mpg combined for 2027, composed of 26 city and 33 highway, with fuel costs around $2,300 a year. Standard all-wheel drive adds friction and weight that front-drive rivals avoid.
That extra drag is the price of the traction owners in snowy regions value so highly. Buyers in mild climates who rarely need the grip may find a front-drive compact more economical to run.
12. Volkswagen Golf GTI: Hot Hatch Last Place
The 2027 Golf GTI is rated at a listed mileage rating of 28 mpg combined, with 25 city and 34 highway, and yearly fuel is estimated at $2,400. Its turbocharged four-cylinder is built for acceleration first, which helps explain why it finishes at the bottom of this group.
Performance-minded buyers get a lively car that still returns a respectable highway number. Anyone chasing low running costs will find the GTI the thirstiest option here, though the penalty is smaller than its reputation suggests.
