Renault Megane Fuel Consumption: Real-World MPG, Engines, Trims, and Efficiency Analysis

Renault Megane in the Modern Hatchback Landscape

The Renault Megane remains a benchmark mid-size hatchback, positioned squarely against long-standing rivals such as the Ford Focus and Volkswagen Golf. While crossover SUVs have eroded the traditional hatchback market, the Megane continues to appeal to drivers prioritising road manners, efficiency, and balanced ownership costs. Renault’s own SUV line-up competes internally, yet the Megane persists as the brand’s most efficiency-focused conventional hatch.

Powertrain Evolution and Efficiency Direction

Renault’s strategic shift toward electrification has redefined the Megane range. Traditional petrol and diesel engines coexisted with high-performance RS variants, while the latest direction places heavy emphasis on hybrid technology. Each powertrain delivers a distinct fuel-consumption profile aligned with specific driving patterns.

Megane E-Tech Plug-in Hybrid Fuel Consumption

The Megane E-Tech plug-in hybrid represents the most efficient iteration of the model.

• Official WLTP combined rating: 235.4 mpg
• Electric-only range: Approximately 30 miles
• Real-world efficiency with depleted battery: 50–60 mpg

When charging frequently and completing short urban trips, petrol usage becomes minimal. Longer motorway journeys see consumption normalise, yet efficiency remains competitive. For drivers unable to plug in regularly, self-charging hybrids such as the Toyota Corolla may deliver marginally lower operating costs.

Diesel Renault Megane MPG Performance

Diesel engines remain the undisputed efficiency champions within the conventional Megane range.

Blue dCi 115 Diesel

Across trims such as Play, Iconic, and GT Line, the 1.5-litre Blue dCi consistently delivers exceptional economy.

• Manual gearbox:
  • Combined: 60.1–62.8 mpg
  • City: 50.4–53.3 mpg
  • Highway: Up to 74.3 mpg
• EDC automatic:
  • Combined: 56.5–61.4 mpg
  • City: ~48.7–50.4 mpg
  • Highway: Up to 70.6 mpg

These figures position the diesel Megane as one of the most economical non-hybrid family hatchbacks available.

Petrol Renault Megane Fuel Consumption

Petrol variants balance respectable economy with lower upfront cost and quieter operation.

TCe 140 Petrol

Available in both manual and EDC automatic transmissions:

• Manual gearbox:
  • Combined: 44.8–48.7 mpg
  • City: 34.9–38.7 mpg
  • Highway: Up to 57.6 mpg
• Automatic EDC:
  • Combined: 42.2–47.9 mpg
  • City: ~31.4–35.8 mpg
  • Highway: Up to 56.5 mpg

Later MY20–MY21 updates show modest efficiency gains, reflecting incremental engine calibration improvements.

Renault Megane RS Fuel Economy

The performance-oriented Megane RS trades economy for output.

RS 280 and RS 300

• Combined MPG: 33.2–35.8 mpg
• City MPG: 23.7–26.2 mpg
• Highway MPG: 38.2–41.5 mpg

These figures underline the RS’s clear focus on driving engagement rather than fuel economy, standing in sharp contrast to the E-Tech hybrid.

Trim-Level Influence on Fuel Consumption

While trims such as Play, Iconic, and GT Line add equipment and styling differentiation, fuel consumption differences remain marginal when engine and gearbox are identical. Wheel size, weight, and optional equipment can cause slight real-world variation, but drivetrain choice dominates efficiency outcomes.

Manual vs Automatic: Efficiency Comparison

Manual transmissions consistently outperform automatics by 2–4 mpg across petrol and diesel engines. However, Renault’s EDC dual-clutch automatics narrow this gap compared to traditional torque-converter systems, offering smoother urban driving with limited efficiency penalty.

Urban, Highway, and Mixed Driving Profiles

• Urban driving: Hybrids and petrol engines perform best due to frequent stop-start conditions.
• Highway driving: Diesel engines achieve outstanding mileage with minimal consumption increase.
• Mixed use: The Blue dCi 115 remains the optimal all-round choice for balanced efficiency.

Fuel Consumption by Measurement Standard

WLTP testing reflects more realistic driving conditions than older NEDC standards. Real-world results typically align closely with WLTP for diesel variants, while plug-in hybrids remain usage-dependent.

Ownership Cost Implications

Fuel efficiency directly impacts long-term ownership costs:

• Lowest fuel spend: E-Tech hybrid with frequent charging
• Best long-distance economy: Blue dCi diesel
• Lowest purchase cost: TCe petrol
• Highest running cost: RS performance variants

Comparative Efficiency Within the Segment

Against direct competitors, the Megane diesel remains class-leading, while the plug-in hybrid offers one of the most accessible entry points into electrified motoring within the segment.

Practical Efficiency Summary Table

• Best overall MPG: Megane E-Tech PHEV
• Best non-hybrid MPG: Blue dCi 115 manual
• Balanced petrol option: TCe 140 MY21 manual
• Performance-focused: Megane RS 300

Recommended Powertrain by Driver Type

• Urban commuter: E-Tech plug-in hybrid
• High-mileage driver: Blue dCi diesel
• Occasional driver: TCe petrol
• Driving enthusiast: RS variant

Long-Term Efficiency Outlook

The Megane’s efficiency story reflects broader industry trends: electrification at the top, diesel excellence for distance driving, and petrol engines offering simplicity and affordability. Each configuration serves a distinct audience with clearly defined consumption expectations.
