Fuel Economy and Luxury: Inside the 2026 Lexus RX 350h Hybrid SUV

When luxury SUV shoppers think about hybrid technology, fuel economy often takes a back seat to performance and comfort. The 2026 Lexus RX 350h challenges that assumption with numbers that deserve attention: 6.5 L/100 km combined fuel consumption. For families seeking premium features without frequent fuel stops, this hybrid SUV offers a strong solution.

The RX 350h pairs its 2.5L four-cylinder hybrid powertrain with 246 hp and 233 lb-ft of torque, proving that efficiency doesn't require sacrificing capability. With 1,585 kg (3,494 lbs) of towing capacity and 838 litres of cargo space, this SUV handles everyday demands while delivering fuel economy that stands out in the luxury segment.

How the RX 350h Achieves 6.5 L/100 km Combined

The hybrid system in the RX 350h combines a 2.5L four-cylinder engine with electric motor assistance to optimize fuel consumption across driving conditions. City driving registers 6.3 L/100 km, while highway efficiency measures 6.8 L/100 km. The combined rating of 6.5 L/100 km reflects real-world driving patterns that mix urban commutes with open-road travel.

This efficiency comes from intelligent powertrain management that smoothly transitions between gasoline and electric power. The system prioritizes electric propulsion during low-speed operation and light acceleration. The gasoline engine provides power when needed for highway merging or passing manoeuvres.

Performance Specifications That Support Daily Driving

The RX 350h generates 246 hp and 233 lb-ft of torque through its hybrid powertrain. These figures support confident acceleration and smooth power delivery across the speed range. The system integrates power from both the gasoline engine and electric motor to provide responsive performance without compromising fuel economy.

Key performance and capability specifications include:

• Power Output: 246 hp (183 kW) system power
• Torque: 233 lb-ft
• Towing Capacity: 1,585 kg (3,494 lbs)
• Cargo Volume: 838 litres behind second row, expanding to 1,308 litres with seats folded

The RX 350h maintains a ground clearance of 206 mm and seats five passengers comfortably. The 2,850 mm wheelbase contributes to interior spaciousness while maintaining a turning circle of 5.9 metres for urban manoeuvrability.

The digital rear view mirror available on Ultra Luxury and Executive trims provides an unobstructed view behind the vehicle regardless of rear seat occupancy or cargo loading.

Dimensions and Practical Considerations

The RX 350h measures 4,890 mm in length, 1,921 mm in width, and 1,710 mm in height. These dimensions create interior space for passengers while maintaining proportions suitable for parking and daily driving. The 2,850 mm wheelbase contributes to rear seat legroom and cargo area depth.

Comparing Fuel Economy Across the RX Lineup

The RX 350h delivers notably lower fuel consumption than the RX 500h across all driving conditions. While the RX 500h offers higher performance with 367 hp and 406 lb-ft of torque from its 2.4L turbocharged hybrid system, the RX 350h prioritizes efficiency for drivers who value fuel economy alongside luxury features.
