2018 Land Rover Discovery 5 Diesel MPG Test: Does Rusty Beat Expectations?

"Rusty" the Discovery 5 Diesel

• 🟡 This video features a 2018 Land Rover Discovery 5, nicknamed "Rusty" due to its color, powered by a 3.0L turbo-diesel engine.
• 💰 The SUV was purchased for just over $20,000 and is described as a luxury vehicle with a premium feel, quiet ride, and a suite of features including a heated windshield and seats.
• 🛠️ Despite its substantial four-wheel-drive system and slightly aggressive, snow-rated Falcon Wild Peak AT tires, the Discovery 5's design is noted to be more aerodynamic than previous models, potentially aiding efficiency.

Engine and Performance

• 🚀 The 3.0L V6 turbo-diesel engine produces 254 horsepower and 443 lb-ft of torque, offering good low-end grunt for off-roading and a smooth, quiet experience on the highway.
• ⚙️ This engine shares similarities with a diesel found in the Ford F-150 from a period when Ford owned Land Rover, indicating shared engineering synergies.
• 💨 The vehicle is equipped with air suspension, currently set to access height for highway travel, but capable of raising for up to 11 inches of ground clearance for off-road use.

The Denver 100 MPG Loop Test

• 🛣️ The team conducted their "Denver 100" MPG loop test, an over 100-mile route designed to provide an average fuel economy reading.
• 📊 The Discovery 5's trip computer initially indicated 28.7 MPG, exceeding its EPA highway rating of 26 MPG.
• ⛽ After topping off the fuel tank and calculating manually using 111 miles and 3.876 gallons, the actual MPG was found to be nearly 29 MPG, matching the trip computer's accuracy.

Conclusion on Fuel Economy

• ✅ The nearly 29 MPG achieved is considered an excellent result for a large, capable SUV that can also handle challenging trails.
• 💡 This performance demonstrates that diesel powertrains remain a strong contender for fuel efficiency, even in luxury SUVs with off-road capabilities.
• 📈 The test suggests that "Rusty" is a practical vehicle for road trips and general use, offering a good balance of luxury, capability, and economy.
