The Chevrolet Blazer has been a popular SUV model for decades, evolving significantly in terms of fuel efficiency and tank capacity over the years. This guide provides a detailed look at how the Blazer’s fuel economy and tank size have changed across different generations and variants, including the latest all-electric Blazer EV.

Fuel Efficiency Comparison Table

Let’s start with a summary table comparing the fuel efficiency of recent Blazer models:

Current Generation Blazer (2019-Present)

The current generation Chevrolet Blazer, introduced in 2019, offers a range of engine options with varying fuel efficiencies:

2.0L Turbocharged 4-Cylinder Engine

This engine, available in more recent model years, provides a good balance of power and efficiency:

– City: 9.4 KM/L (22 MPG)
– Highway: 12.3 KM/L (29 MPG)
– Combined: 10.6 KM/L (25 MPG)

3.6L V6 Engine

The V6 option offers more power but with a slight reduction in fuel economy:

– City: 9.3 KM/L (22 MPG)
– Highway: 12.9 KM/L (27 MPG)
– Combined: 10.8 KM/L (24 MPG)

Fuel Tank Capacity

The current generation Blazer has a fuel tank capacity of 67 liters (17.7 gallons), providing a good range for both city and highway driving.

Blazer EV (2024 Model Year)

The all-new Blazer EV represents a significant shift in Chevrolet’s approach to fuel efficiency:

Range and Efficiency

– Estimated range: Up to 515 km (320 miles) on a full charge for the RS RWD model
– Efficiency: Approximately 6.8 KM/L (16 MPGe) combined

Battery Capacity

The Blazer EV comes with two battery options:
– Standard: 85 kWh
– Extended Range: 102 kWh

Charging Capabilities

– DC Fast Charging: Up to 190 kW, adding up to 126 km (78 miles) of range in 10 minutes
– Level 2 (AC) Charging: 11.5 kW standard, with 19.2 kW available on some trims

Historical Blazer Models

To understand how far the Blazer has come in terms of fuel efficiency, let’s look at some historical models:

Second Generation K5 Blazer (1973-1991)

The full-size Blazer of this era was known more for its ruggedness than fuel efficiency:

– 250 cu in (4.1 L) inline-six engine (1974 model):
– Highway efficiency: 13.69 KM/L (16.44 MPG)

– 350 V8 engine (1973 model):
– Observed efficiency at 45 mph: 9.65 KM/L (11.59 MPG)

Fuel Tank Capacity

The K5 Blazer typically came with a large fuel tank to compensate for its lower efficiency:

– Standard tank: 117 liters (31 gallons)

This large tank capacity was necessary for the vehicle’s off-road capabilities and to provide a reasonable driving range despite its lower fuel economy.

Factors Affecting Blazer Fuel Efficiency

Several factors contribute to the Blazer’s fuel efficiency across different generations:

1. Engine Technology

Modern Blazers benefit from advanced engine technologies like direct injection and turbocharging, which improve fuel efficiency without sacrificing power.

2. Vehicle Weight

The transition from body-on-frame construction to unibody design in the current generation has reduced overall vehicle weight, contributing to better fuel economy.

3. Aerodynamics

Contemporary Blazer models feature more aerodynamic designs, reducing drag and improving highway fuel efficiency.

4. Transmission Advancements

The use of advanced multi-speed automatic transmissions helps optimize engine performance and fuel economy across various driving conditions.

5. Drivetrain Options

The availability of front-wheel drive, all-wheel drive, and now electric drivetrains allows consumers to choose the most efficient option for their needs.

Real-World Fuel Economy Data

While manufacturer-provided fuel economy figures are useful, real-world data often provides a more accurate picture of what owners can expect:

User-Reported Fuel Economy

According to data from Fuelly.com, based on real-world driving experiences:

– 2024 Blazer: 20.6 MPG average (11.4 KM/L)
– 2023 Blazer: 21.9 MPG average (12.1 KM/L)
– 2022 Blazer: 20.5 MPG average (11.3 KM/L)
– 2021 Blazer: 21.4 MPG average (11.8 KM/L)
– 2020 Blazer: 21.7 MPG average (12.0 KM/L)

These figures are based on a significant number of vehicles and fuel-ups, providing a reliable indication of real-world performance.

Blazer EV Efficiency Considerations

The introduction of the Blazer EV brings new considerations for efficiency:

1. Driving Conditions

Electric vehicles typically perform better in city driving due to regenerative braking, which can recapture energy normally lost during deceleration.

2. Temperature Effects

Extreme temperatures, both hot and cold, can affect the range and efficiency of electric vehicles. The Blazer EV’s battery management system works to mitigate these effects.

3. Charging Efficiency

The efficiency of charging can vary depending on the charging method used. DC fast charging is quicker but may be slightly less efficient than slower Level 2 AC charging.

Comparing Blazer Efficiency to Competitors

To put the Blazer’s fuel efficiency into context, let’s compare it with some key competitors in the midsize SUV segment:

2024 Ford Edge (2.0L EcoBoost)

– City: 9.8 KM/L (23 MPG)
– Highway: 12.8 KM/L (30 MPG)
– Combined: 11.1 KM/L (26 MPG)

2024 Honda Passport (3.5L V6)

– City: 8.9 KM/L (21 MPG)
– Highway: 11.5 KM/L (27 MPG)
– Combined: 10.2 KM/L (24 MPG)

2024 Hyundai Santa Fe (2.5L 4-cylinder)

– City: 9.8 KM/L (23 MPG)
– Highway: 11.9 KM/L (28 MPG)
– Combined: 10.6 KM/L (25 MPG)

The Blazer’s fuel efficiency is competitive within its class, especially when equipped with the 2.0L turbocharged engine.

Tips for Maximizing Blazer Fuel Efficiency

Regardless of the Blazer model or generation, there are several ways owners can maximize their fuel efficiency:

1. Regular Maintenance

Keeping up with scheduled maintenance, including oil changes and air filter replacements, ensures the engine operates at peak efficiency.

2. Proper Tire Inflation

Maintaining the correct tire pressure reduces rolling resistance, improving fuel economy.

3. Smooth Driving Habits

Avoiding rapid acceleration and hard braking can significantly improve real-world fuel economy.

4. Use of Cruise Control

On highway trips, using cruise control helps maintain a steady speed, optimizing fuel consumption.

5. Reduce Excess Weight

Removing unnecessary items from the vehicle reduces weight and improves efficiency.

6. Plan Trips Efficiently

Combining errands into single trips can reduce overall fuel consumption.

Future of Blazer Fuel Efficiency

As Chevrolet continues to develop the Blazer line, we can expect further improvements in fuel efficiency:

1. Hybrid Technology

While not currently offered, a hybrid Blazer could significantly improve fuel economy, especially in city driving.

2. Advanced Materials

The use of lightweight materials in future models could further reduce vehicle weight, improving efficiency across all powertrains.

3. Expanded EV Options

As battery technology improves, we may see Blazer EV models with even greater range and efficiency.

4. Aerodynamic Improvements

Continued refinements in vehicle aerodynamics could lead to better highway fuel economy for both ICE and EV models.

Conclusion

The Chevrolet Blazer has come a long way in terms of fuel efficiency since its inception. From the gas-guzzling V8s of the K5 era to the modern turbocharged engines and the all-new electric Blazer EV, each generation has seen improvements in technology and efficiency.

Today’s Blazer offers a range of options to suit different needs and preferences, from the balanced performance of the 2.0L turbocharged engine to the zero-emissions capability of the Blazer EV.
