Quiet Champs Vs. Loud Guzzlers
Not all sedans are built with the same appetite. Some are surprisingly light on their fuel cravings, while others show up like they’ve never met a gas station. In a world where hybrid systems and turbo engines are becoming the norm, it's easy to miss who’s actually doing it best—or worst. That’s where this roundup steps in, separating the 10 frugal from the 10 ferocious.
1. 2025 Toyota Crown
When Toyota decided to reinvent the traditional sedan format, it created something unprecedented. The 2025 Crown achieves an impressive 41 mpg combined while offering SUV-like ground clearance and standard all-wheel drive. Its elevated design houses a 2.5-liter hybrid system.
2. 2025 Toyota Camry Hybrid
Every 2025 Camry now comes exclusively with hybrid power, marking the first time in the model's history without a V6 or traditional four-cylinder option. The payoff is substantial: 51 mpg in front-wheel-drive trim, with all-wheel-drive versions managing 49 mpg combined.
3. 2024 Toyota Corolla Hybrid
At just under $25,000, this represents the cheapest entry point into hybrid sedan ownership available today. What makes it special is that Toyota's engineers borrowed the proven 1.8-liter engine from the previous Prius generation and obtained 50 mpg together.
4. 2025 Honda Accord Hybrid
Forget everything you know about hybrid compromises. Honda's hybrid system doesn't just match the regular Accord's performance but destroys it with 204 horsepower. The EX-L trim, equipped with smaller wheels, maximizes efficiency while the two-motor system intelligently switches between 3 drive modes.
5. 2025 Hyundai Sonata Hybrid
That distinctive fastback roofline is Hyundai's bold rejection of a boring three-box sedan layout. The 2.0-liter four-cylinder engine teams with an electric motor to produce 192 horsepower and 47 mpg. Hyundai's confidence shows in their 10-year, 100,000-mile hybrid component warranty.
6. 2025 Hyundai Elantra Hybrid
Compact sedans rarely break the 50-mpg barrier, but the Elantra Hybrid demolishes expectations. This brilliant efficiency stems from downsizing to a 1.6-liter engine, compared to the regular Elantra's 2.0-liter unit. Additionally, the SmartSense safety suite includes forward collision avoidance.

7. 2025 Nissan Versa
Being America's cheapest new car doesn't mean cutting corners on safety. The Versa includes automatic emergency braking and blind spot warning as standard equipment. The 1.6-liter four-cylinder produces around 122 horsepower, but that modest output translates to nearly 35 mpg.
8. 2024 Lexus ES 300h
At 44 mpg, this beast outperforms every luxury competitor while retaining the refined ride quality Lexus buyers expect. The secret lies in sharing Camry's proven hybrid powertrain while adding extensive sound deadening. Lexus provides a 10-year, 150,000-mile hybrid battery warranty.
9. 2025 Honda Civic Sedan
The mature, upscale structure of this car marks a dramatic departure from the aggressive styling of previous generations. Featuring 14.8 cubic feet of trunk space, the Civic Sedan achieves 36 mpg together from its efficient 2.0-liter naturally aspirated engine.

10. 2025 Nissan Sentra
Long-distance comfort gets scientific treatment with Nissan's Zero Gravity seats, engineered to reduce driver fatigue. Updated LED headlights and a revised grille gave the compact sedan fresh styling for 2024. It possesses a standard 2.0-liter four-cylinder and CVT transmission.
Now let's look at those automobiles that gulp down gas like there's no tomorrow.
1. 2024 Cadillac CT5-V Blackwing
America's last manual transmission, rear-wheel-drive sedan is a dying breed that burns rubber with authority. The hand-built supercharged 6.2-liter V8 cranks out 668 horsepower while delivering dismal fuel economy. This is just 15 mpg combined with the six-speed manual.

3. 2024 BMW M8 Gran Coupe
Four doors don't make this a traditional sedan. BMW's "Gran Coupe" classification reflects its low, sloping roofline that prioritizes style over practicality. With the optional Driver's Package, this rocket reaches a limited top speed of 190 mph but has low fuel efficiency.

4. 2024 Mercedes-AMG E63 S
Here comes the final chapter for pure gasoline V8 power in Mercedes-AMG's E-Class lineup. The twin-turbocharged 4.0-liter V8 delivers 603 horsepower and 627 lb-ft of torque, but its consumption rate takes a backseat at 16 mpg city and 23 mpg highway.
5. 2024 Rolls-Royce Ghost
Ultra-luxury comes at a fuel economy price that would make environmentalists weep. The Ghost's massive 6.75-liter twin-turbocharged V12 produces 563 horsepower, but achieves only 12 mpg city and 19 mpg highway, resulting in a combined fuel economy of 14 mpg.

6. 2024 Genesis G90
When it comes to the Genesis G90, the base 3.5-liter twin-turbo V6 hits 18 mpg city and 26 mpg highway. However, upgrading to the available 5.0-liter V8 results in a drop in efficiency to 15 mpg city and 23 mpg highway.
7. 2024 Bentley Flying Spur W12
Hand-stitched luxury meets the harsh reality of fuel consumption in this British masterpiece. The W12 engine produces 626 horsepower with mountain-moving torque, but delivers an abysmal 12 mpg city and 19 mpg highway. Its fuel tank capacity is 90 liters (23.8 gallons).
8. 2024 Lexus LS 500
Most luxury sedans use eight or 9-speed transmissions. Then, Lexus entered, choosing an unusual 10-speed automatic for efficiency optimization. As a full-size luxury sedan, the LS 500 is heavy and tends to prioritize comfort and refinement over lightweight dynamics.
9. 2024 Mercedes-Benz S-Class S500
Mercedes' MBUX infotainment system centers around a massive 12.8-inch OLED display that commands the dashboard like a digital command center. With opulent rear legroom, the mild hybrid S500 gets 21 mpg in the town and 31 mpg on the highway.
