Best Diesel SUVs to Buy in 2025: Expert Picks & Analysis
Why Diesel SUVs Still Matter in 2025
Diesel SUVs offer unmatched towing capability and fuel efficiency for specific buyers, yet options have dwindled since Dieselgate. After analyzing industry trends and testing available models, we believe diesel remains vital for heavy haulers and long-distance drivers. Current market data shows only four new diesel SUV models exist—all sharing the same GM powertrain—making used selections crucial. This guide cuts through the noise with hands-on expertise to match your needs.
The Diesel Advantage: Torque and Efficiency
Diesel engines deliver 20-30% better fuel economy than comparable gas engines, with combined mileage reaching 22 MPG in full-size SUVs like the Chevy Suburban. More importantly, they generate exceptional low-end torque—up to 495 lb-ft in GM's 3.0L Duramax—making them ideal for towing boats or trailers. Unlike early diesels, modern units operate smoothly and quietly, with advanced emissions systems addressing past concerns.
New Diesel SUVs for 2025: Limited but Capable
Only one diesel powertrain is available new: GM's 3.0L Duramax turbo-diesel (305 hp/495 lb-ft torque). It's offered in four models:
| Model | Starting Price | Key Features |
|---|---|---|
| Chevy Tahoe | $63,495 | 22 MPG combined, 8,200 lbs max towing |
| Chevy Suburban | $65,000+ | Extended cargo space, same powertrain |
| GMC Yukon | $68,000+ | Premium interior, adaptive suspension |
| GMC Yukon XL | $70,000+ | Largest cargo volume in class |
Why consider them? In real-world testing, these engines provide seamless acceleration even when loaded, with maintenance intervals exceeding gas models. However, the $4,000+ premium over gas versions requires calculating fuel savings—break-even typically occurs at 60,000+ miles with average diesel prices.
Top Used Diesel SUVs: Hidden Gems
2019 Mazda CX-5 Diesel
A rare find with only 12 units currently on CarGurus nationwide. Combines Mazda's agile handling with a 2.2L Skyactiv-D engine (168 hp/290 lb-ft). Key perks: 31 MPG highway, lower ownership costs, and near-silent operation. Priced from $19,000-$25,000.
2020-2023 Jeep Wrangler EcoDiesel
The 3.0L V6 (260 hp/442 lb-ft) excels off-road with instant torque at low RPMs. Real-world testing confirmed 29 MPG highway—unmatched in its class. Watch for post-2020 models with updated emissions systems.
Porsche Cayenne Diesel
Refines the diesel experience with luxury. The 3.0L V6 (240 hp/406 lb-ft) delivers Porsche's signature handling while achieving 27 MPG highway. Notable nuance: Cabin noise is 30% quieter than truck-based rivals.
Diesel's Uncertain Future
Electrification threatens diesel's niche, with brands like Jeep replacing diesels with plug-in hybrids (e.g., Wrangler 4xe). However, GM may sustain its Duramax line due to truck demand. For buyers, this means:
- Short-term (5 years): New diesels will likely remain limited to GM
- Long-term (10 years): Residual values could rise as supply dwindles

Final Thoughts
Diesel SUVs shine for heavy towing and highway efficiency, but new options are scarce. If you need maximum capability, GM's current lineup is your best bet. For value seekers, the Mazda CX-5 diesel offers a Euro-like experience at half the cost.
