Top Factors to Consider for Fuel Efficiency:

When you’re on the hunt for a fuel-efficient used car, several key factors will influence how much you spend at the pump. Understanding these will help you make an informed decision:

• MPG Ratings (City/Highway/Combined): Miles Per Gallon (MPG) ratings, or in Australia, typically litres per 100 kilometres (L/100km), are crucial indicators of a vehicle’s fuel consumption. These figures are usually presented as city, highway, and combined ratings.

  • City: This rating reflects fuel economy in urban driving conditions, characterised by stop-start traffic and lower speeds.
  • Highway: This rating indicates fuel efficiency at consistent, higher speeds on open roads.
  • Combined: This is a weighted average of the city and highway ratings, giving you a more general idea of expected fuel consumption in mixed driving conditions. When comparing vehicles, pay close attention to the combined figure as it often provides the most realistic estimate for everyday driving. Lower L/100km figures indicate better fuel efficiency.

• Engine Type and Size: The engine is a primary determinant of fuel consumption. Generally:

  • Smaller Engines: Tend to be more fuel-efficient, especially in city driving, as they require less fuel to produce power. However, they might work harder and consume more fuel at higher speeds or when carrying heavy loads.
  • Hybrid Engines: Combine a traditional petrol engine with an electric motor and battery. They offer significant fuel savings, particularly in stop-start city driving, as the electric motor can power the vehicle at lower speeds or assist the petrol engine.
  • Diesel Engines: Historically known for their better fuel economy on longer journeys compared to petrol engines, especially for larger vehicles. Modern diesel engines are also cleaner than older models, but it’s worth considering potential higher maintenance costs and specific emissions requirements.

• Transmission Type: The type of transmission can also have a subtle impact on fuel efficiency:

  • Manual Transmissions: Can sometimes offer slightly better fuel economy than traditional automatic transmissions, as the driver has more control over gear selection and engine RPM.
  • Automatic Transmissions (including CVTs): Modern automatic transmissions, especially Continuously Variable Transmissions (CVTs), are often designed for optimal fuel efficiency by keeping the engine in its most efficient rev range. CVTs generally offer smooth and efficient power delivery.

• Vehicle Weight and Aerodynamics: A heavier vehicle requires more energy to move, thus consuming more fuel. Similarly, a more aerodynamic design allows the car to move through the air with less resistance, improving fuel economy, particularly at higher speeds. Sleek, lower-profile cars generally have better aerodynamics than boxier SUVs.

• Maintenance and Driving Habits: Even the most fuel-efficient car won’t perform optimally if it’s not well-maintained or if driven inefficiently.

  • Regular Maintenance: Ensuring the engine is properly tuned, tyres are correctly inflated, and air filters are clean can significantly impact fuel consumption.
  • Efficient Driving Habits: Smooth acceleration and braking, avoiding unnecessary idling, and maintaining a consistent speed can all contribute to better fuel economy. Aggressive driving with rapid acceleration and hard braking wastes fuel.

Hybrids:

• Why They’re Efficient: Hybrid vehicles combine a traditional internal combustion engine (usually petrol) with an electric motor and a battery. The electric motor can assist the petrol engine, power the car at lower speeds, and recapture energy during braking (regenerative braking) to recharge the battery. This synergy significantly reduces fuel consumption, especially in stop-start city driving.

• Example 1: Toyota Prius (e.g., 2010-2015 models)

• • Key Fuel Efficiency Figures:

    • Combined Fuel Consumption: Approximately 3.9 – 4.0 litres per 100 kilometres.
    • City Driving: Often achieves even lower fuel consumption figures due to the electric motor’s greater involvement in stop-start conditions.
    • Highway Driving: While still efficient, fuel economy on the open road might be slightly higher than in the city, but remains competitive.

This inherent property allows diesel engines to extract more kilometres from each litre of fuel. Modern common-rail diesel engines are also designed for efficient combustion and often produce more torque at lower RPMs, which can contribute to better fuel economy, especially on longer journeys and when carrying loads.

• Example 1: Volkswagen Jetta TDI (e.g., Mk6 generation, 2011-2018)

• • Key Fuel Efficiency Figures: Depending on the specific engine (typically a 2.0L TDI), expect combined fuel consumption figures in the range of 4.5 – 5.5 L/100km. Highway driving often sees the best fuel economy due to the engine’s characteristics at consistent speeds.
  • Other Benefits: Diesel engines generally produce higher torque, resulting in strong pulling power and comfortable cruising at highway speeds. The Jetta TDI often offers a more refined driving experience compared to some petrol counterparts in its class. Diesel engines can also be quite durable and long-lasting with proper maintenance.

Tips for Finding and Buying a Fuel-Efficient Used Car:

Finding the right fuel-efficient used car requires a thoughtful approach. Here are some valuable tips to guide your search and purchase:

• Set a Realistic Budget: Before you even start browsing, determine a clear and realistic budget. This should encompass not only the initial purchase price but also factor in potential immediate maintenance or repairs, registration fees, and insurance costs. Remember that even fuel-efficient cars require upkeep.

• Research Specific Models and Years: Don’t just look at car categories; delve into specific makes and models known for consistently high fuel economy ratings and a strong track record of reliability. Research owner reviews and common issues associated with particular years to make an informed decision. Some years within a model’s production run might be more fuel-efficient or reliable than others.

• Check Fuel Economy Data: Utilise reputable resources, such as government fuel economy websites (in Australia, the Green Vehicle Guide is a good starting point), to find official fuel consumption figures (L/100km) for the specific models and years you are considering. Compare these figures across different options to see the potential savings.

• Inspect Vehicle History Reports: As with any used car purchase, always obtain a comprehensive vehicle history report (like Carfax or AutoCheck, if available in your region). This report can reveal crucial information about the car’s past, including accident history, title issues, and reported maintenance, which can indirectly impact fuel efficiency (e.g., poor maintenance can lead to higher fuel consumption).

• Test Drive Thoroughly: A comprehensive test drive is essential. Pay close attention to how the engine performs – is it smooth and responsive? Listen for any unusual noises or vibrations. Assess the overall driving feel, including acceleration, braking, and handling. A car that isn’t running smoothly is unlikely to be fuel-efficient.

• Consider a Pre-Purchase Inspection (PPI): Investing in a pre-purchase inspection by an independent, trusted mechanic is highly recommended. They can assess the car’s mechanical condition, identify any potential problems that could affect fuel efficiency (like engine issues or worn components), and provide you with an unbiased opinion before you commit to buying.
