Top Fuel-Efficient Pickup Trucks of 2025: A Closer Look

2025 Chevrolet Silverado & GMC Sierra 1500 Diesel | 26 MPG

The 2025 Chevrolet Silverado and GMC Sierra 1500 Diesel trucks are perfect for those who need a robust engine that also delivers solid fuel efficiency. With the Duramax 3.0L I-6 diesel engine, you'll get an impressive 460 lb-ft of torque---making these trucks powerful yet surprisingly economical. Both trucks offer excellent highway fuel economy, and their diesel engines help you travel farther on a gallon of fuel, even if diesel prices fluctuate.

Though the diesel option adds a bit to the price, with the Silverado LT starting at $52,385, it's an investment if you plan on doing a lot of long-distance driving or towing. The base model, however, is still affordable, and the fuel efficiency is among the best in the full-size truck category.
