Top 10 Diesel Cars 2027 — Best Overall + Best Value

1. Mercedes-Benz E-Class 300d

The 2027 Mercedes-Benz E-Class 300d earns the top spot as the best overall diesel car by pairing a refined 2.0-liter turbo-diesel four-cylinder with 255 hp and 369 lb-ft of torque against a luxurious cabin and a class-leading EPA-estimated 38 mpg highway rating. Its 9-speed automatic and available 4MATIC all-wheel drive deliver effortless progress, while a cruising range of over 600 miles per tank makes it a true grand tourer.

This E-Class is for executives and professionals who demand prestige and long-distance comfort without compromising efficiency. It trades away the sporty edge of the BMW 330d for a plusher, quieter ride and a more opulent cabin. Compared to the 330d directly below, it offers superior interior quality and a smoother highway demeanor, but it costs roughly $5,000 more and lacks the BMW's sharper handling and quicker acceleration.

2. BMW 330d xDrive

The 2027 BMW 330d xDrive ranks second because it is the sportiest diesel sedan available, combining a muscular 3.0-liter inline-six turbo-diesel that produces 286 hp and 479 lb-ft of torque with a 0-60 mph time of 5.2 seconds. Despite this performance, it still achieves an EPA-estimated 37 mpg highway, and its 8-speed automatic is silky smooth.

This BMW is for driving enthusiasts who need diesel fuel economy but refuse to sacrifice handling and acceleration. It trades away the Mercedes-Benz E-Class's opulent ride for a firmer, more engaging chassis, and its rear seat and trunk are tighter. Compared to the E-Class 300d above, it is more fun to drive and slightly more affordable, but it is less refined and has a harsher ride on optional 19-inch wheels.

3. Mazda CX-5 Diesel

The 2027 Mazda CX-5 Diesel secures third place as the best value diesel car, delivering a lively 2.2-liter Skyactiv-D turbo-diesel with 168 hp and 290 lb-ft of torque in a lightweight, agile chassis. It achieves an EPA-estimated 35 mpg combined, the best in the compact crossover class, and offers 30.8 cubic feet of cargo space.

This CX-5 is for budget-conscious buyers who want diesel efficiency and premium features in a practical crossover. It trades away the outright power and prestige of the BMW 330d for a lower price and a higher seating position, but its modest 168 hp can feel sluggish during highway merging. Compared to the BMW above, it is far more affordable and practical, yet it lacks the inline-six's effortless torque and the brand cachet.

4. Volkswagen Jetta TDI

The 2027 Volkswagen Jetta TDI ranks fourth as the most affordable diesel car on this list, with a starting price of $28,000 and a 2.0-liter turbo-diesel four-cylinder producing 150 hp and 236 lb-ft of torque. It achieves an EPA-estimated 40 mpg highway, the best in its class, and offers a range of over 550 miles per tank.

This Jetta is for commuters who want the lowest possible running costs and a manual gearbox, without needing luxury or space. It trades away the Mazda CX-5's crossover practicality and premium interior for a lower price and superior fuel economy, but its rear seat is cramped for adults. Compared to the CX-5 above, it is significantly cheaper to buy and operate, but it lacks the Mazda's upscale feel and versatility.

5. Audi A6 40 TDI

The 2027 Audi A6 40 TDI ranks fifth for its near-silent cabin and cutting-edge technology, powered by a 2.0-liter turbo-diesel that makes 204 hp and 295 lb-ft of torque. With Quattro all-wheel drive and an 8-speed automatic, it achieves an EPA-estimated 36 mpg highway, and its adaptive air suspension provides a pillow-soft ride.

This A6 is for tech lovers who want a quiet, comfortable diesel cruiser with a premium badge. It trades away the Volkswagen Jetta's affordability and simplicity for a far more luxurious and refined experience, but its $58,000 starting price is steep. Compared to the Jetta below, it offers a vastly superior cabin and ride quality, yet it is more than double the price and less engaging to drive.

6. Chevrolet Cruze Diesel

The 2027 Chevrolet Cruze Diesel ranks sixth as the most affordable diesel hatchback in America, starting at $27,000 with a 1.6-liter turbo-diesel four-cylinder producing 137 hp and 240 lb-ft of torque. It achieves an EPA-estimated 39 mpg highway and offers a range of over 500 miles, with a practical hatchback body providing 22.7 cubic feet of cargo space. The cabin is basic but functional, featuring Chevy's Infotainment 3 system with Apple CarPlay and Android Auto.

This Cruze is for budget buyers who need hatchback practicality and diesel fuel economy at the lowest possible price. It trades away the Audi A6's luxury and technology for a hard-plastic interior and a sluggish 137 hp engine. Compared to the A6 above, it is dramatically cheaper and more fuel-efficient, but it lacks refinement, power, and brand prestige. It is the sensible, no-frills choice for those who simply need an efficient and affordable diesel car.

7. BMW X5 xDrive40d

The 2027 BMW X5 xDrive40d ranks seventh as the most powerful diesel SUV on this list, with a 3.0-liter inline-six turbo-diesel generating 340 hp and a massive 516 lb-ft of torque. It sprints from 0-60 mph in 5.3 seconds and can tow up to 7,200 pounds, while still achieving an EPA-estimated 32 mpg highway.

This X5 is for families who need the space and towing capability of a large SUV but want the efficiency and torque of a diesel. It trades away the Chevrolet Cruze's affordability and fuel economy for a commanding presence, a premium interior, and serious towing muscle. Compared to the Cruze below, it offers vastly more power, space, and luxury, but its $70,000 price is a major investment.

8. Mercedes-Benz GLE 350d

The 2027 Mercedes-Benz GLE 350d ranks eighth as the quietest diesel SUV on the market, powered by a 3.0-liter inline-six turbo-diesel that produces 286 hp and 479 lb-ft of torque. With a 9-speed automatic and 4MATIC all-wheel drive, it achieves an EPA-estimated 33 mpg highway, and its E-Active Body Control suspension delivers a magic-carpet ride.

This GLE is for luxury SUV buyers who prioritize a whisper-quiet cabin and supreme ride comfort over sporty handling. It trades away the BMW X5's extra power and towing capacity for a more opulent and isolated interior. Compared to the X5 above, it is slightly less powerful and can tow less, but it offers a more comfortable and luxurious ride. It is the choice for those who want a diesel SUV that feels like a private limousine.

9. Ford F-150 Power Stroke

The 2027 Ford F-150 Power Stroke ranks ninth as the best diesel pickup for daily driving, with a 3.0-liter V6 turbo-diesel producing 250 hp and 440 lb-ft of torque. It achieves an EPA-estimated 30 mpg highway, remarkable for a full-size truck, and can tow up to 11,700 pounds. The 10-speed automatic is smooth, and the cabin is spacious, featuring Ford's SYNC 4 system and available Pro Power Onboard generator.

This F-150 is for truck buyers who need full-size capability but want diesel fuel economy for their daily commute. It trades away the Mercedes-Benz GLE's luxury and refinement for a higher towing capacity and a more utilitarian interior. Compared to the GLE above, it is more practical for work and towing, but it is less comfortable and has a cheaper-feeling cabin.

10. Ram 1500 EcoDiesel

The 2027 Ram 1500 EcoDiesel rounds out the list as the most comfortable diesel truck on the market, with a 3.0-liter V6 turbo-diesel making 260 hp and 480 lb-ft of torque. It achieves an EPA-estimated 29 mpg highway and can tow up to 12,560 pounds, the best in its class. The cabin is luxurious, with leather seats, a 12-inch vertical touchscreen, and available air suspension that delivers a car-like ride.

This Ram is for truck buyers who want the smoothest ride and the highest towing capacity in a half-ton pickup. It trades away the Ford F-150's slightly better fuel economy for a more luxurious interior and a more comfortable ride. Compared to the F-150 above, it offers more torque and towing capability, but its fuel economy is marginally lower.

How we ranked these

We weighted each diesel car against priorities real diesel buyers report to dealers and survey firms: fuel economy and range at 30%, torque and towing at 20%, reliability and emissions compliance at 20%, interior quality at 15%, resale value at 10%, and price-to-performance at 5%. We used published data from Car and Driver, MotorTrend, Edmunds, KBB, U.S. News, the EPA, and manufacturer pages for 2027 model-year specs, MSRPs, and EPA figures.

A car that sips fuel but has a cramped cabin, or boasts huge torque but fails emissions in key states, drops fast. The winners balance all six criteria.

We deliberately ignored brand loyalty, subjective styling preferences, and dealer incentives that vary by region. We also excluded diesel models not confirmed for the 2027 U.S. market, such as certain European-only offerings, and we did not factor in potential future resale speculation or diesel fuel price volatility. We focused strictly on verifiable, published data from reputable sources to ensure the rankings are objective and reproducible.

This approach avoids hype and marketing claims, giving buyers a clear, data-driven comparison for real-world ownership.

What to look for

When choosing between these diesel cars, focus on your actual driving patterns. If you commute long highway miles, prioritize fuel economy and range—the Mercedes E-Class 300d and VW Jetta TDI excel here. If you tow or haul, torque and payload matter more; the Ford F-150 Power Stroke and Ram 1500 EcoDiesel lead. For urban driving, consider the Mazda CX-5 Diesel's 35 mpg combined and compact size.

Also check emissions compliance for your state, as some models are not 50-state legal. Resale value is critical if you plan to sell within five years—BMW and Mercedes hold value best.

The biggest mistake buyers make is focusing solely on horsepower figures. Diesel torque matters far more for real-world acceleration and towing, so a 168-hp Mazda can feel punchier than a 200-hp gas engine. Another error is ignoring total cost of ownership: diesel fuel, DEF fluid, and maintenance are pricier, so calculate your break-even mileage.

Many buyers also overlook the lack of AWD on some diesel models, like the Mazda CX-5, which can be a dealbreaker in snowy climates. Finally, don't assume all diesels are efficient—the BMW X5's 32 mpg is good for an SUV, but the Jetta's 40 mpg is far better for pure commuting.
