Diesel engines are available in a variety of vehicles, primarily in heavy-duty pickup trucks, full-size SUVs, and certain European-brand sedans and wagons. For the average American driver, the most common and accessible diesel vehicles are the heavy-duty versions of the Ford F-Series, Ram Trucks, and Chevrolet Silverado/GMC Sierra. Outside of the truck and SUV segment, options are more limited but include models like the Chevrolet Equinox Diesel and historically, passenger cars from brands like BMW, Mercedes-Benz, and Audi.
The key advantage of a diesel engine is torque, which is the twisting force that provides strong low-end power. This makes diesel-powered vehicles exceptional for towing and hauling heavy loads. They are also generally more fuel-efficient than comparable gasoline engines, especially on the highway. However, the higher upfront cost of a diesel vehicle and the typically higher price of diesel fuel are important factors to consider.
If your primary needs involve frequent long-distance highway driving, substantial towing, or demanding payloads, a diesel truck or SUV is an excellent choice. For daily commuting in stop-and-go traffic, a gasoline or hybrid vehicle is often more practical and cost-effective.
The table below outlines some popular diesel models available in the U.S. market, highlighting their key specifications.
| Vehicle Model | Engine | Horsepower | Torque (lb-ft) | EPA Est. MPG (Combined) | Key Feature |
|---|---|---|---|---|---|
| Ford F-250 Super Duty | 6.7L Power Stroke V8 | 475 hp | 1,050 lb-ft | ~20 mpg | Best-in-class torque |
| Ram 2500 Heavy Duty | 6.7L Cummins Turbo I6 | 370 hp | 850 lb-ft | ~19 mpg | Proven Cummins engine reliability |
| Chevrolet Silverado 2500HD | 6.6L Duramax Turbo I6 | 470 hp | 975 lb-ft | ~21 mpg | Strong towing capacity |
| Jeep Grand Cherokee | 3.0L EcoDiesel V6 | 260 hp | 480 lb-ft | ~26 mpg | Diesel option in a midsize SUV |
| Chevrolet Equinox Diesel | 1.6L Turbo I4 | 137 hp | 240 lb-ft | ~32 mpg | High fuel economy for a compact SUV |

You're looking at heavy-duty trucks, mostly. Think Ford F-250s, Ram 2500s, and Chevy/GMC 2500s. They're built for work—towing giant trailers or hauling heavy loads in the bed. Some big SUVs like the Chevy Tahoe or Jeep Grand Cherokee have had diesel options too. They give you crazy pulling power and better gas mileage on the open road, but you pay more for the truck and the fuel. For most daily driving, it's overkill.

Beyond the big American trucks, your best bet for a diesel car is often a used European model. Brands like BMW, Mercedes, and Audi have sold diesel versions of sedans and wagons here. They're less common, but they offer a unique blend of quiet, refined highway cruising and excellent fuel range. The challenge can be finding them and ensuring you have a good mechanic familiar with these engines. They're a niche choice for drivers who prioritize long-distance comfort and efficiency.

My neighbor is a contractor and swears by his diesel pickup. He says the fuel cost evens out because he gets almost double the mileage when towing his equipment trailer compared to his old gas truck. He doesn't worry about mountain grades anymore; the truck just pulls. But he also admits it was a significant investment. For him, it's a business tool that saves time and stress on job sites. For someone who doesn't tow, he thinks it wouldn't make much financial sense.
