How much fuel does a Subaru use per 100km?

Fuel consumption per 100 km for a Subaru varies by model, year, and configuration. In general, most gasoline Subarus sold recently hover around 7.5–9.0 L/100 km (roughly 26–31 mpg) in combined driving. The Crosstrek Hybrid is notably more efficient, typically around 6.5–7.0 L/100 km (about 36–38 mpg).

What affects fuel economy in Subarus?

Several factors influence how much fuel a Subaru uses per 100 km: engine size and type, drivetrain (all-wheel drive adds weight and friction), aerodynamics, tire choice and pressure, cargo and occupants, driving style, temperature, and whether the vehicle is operating in city stop-and-go or on long highway stretches. EPA ratings represent standardized testing under specific conditions and real-world results can vary by a notable margin.

Typical ranges for current Subaru gasoline models

The following ranges reflect common configurations in recent model years (EPA combined estimates), presented in both liters per 100 kilometers and miles per gallon for context. Note that hybrids and performance trims may differ significantly.

• Gasoline models with a 2.5L four-cylinder engine (most Forester, Outback, Legacy variants): 7.5–9.0 L/100 km (26–31 mpg) combined.


• Gasoline models with turbocharged or larger engines (2.0L or 2.4L turbo options in WRX, Outback, Ascent): 8.5–11.0 L/100 km (26–21 mpg) combined.


• Subarus with the 2.0L naturally aspirated or 2.0L turbo configurations in lighter duty cars (e.g., Impreza/WRX variants): around 8.0–9.5 L/100 km (29–25 mpg) combined.


• Crosstrek (2.0L, non-hybrid): ~7.8–8.2 L/100 km (29–28 mpg) combined.


• Crosstrek Hybrid (2.0L Atkinson-cycle plus electric): 6.5–7.0 L/100 km (36–38 mpg) combined.

Across these categories, turbocharged and larger-engine models tend to consume more fuel, especially in city driving or when the vehicle is loaded. Hybrids offer a meaningful efficiency advantage, while the Crosstrek base model remains a relatively frugal option among gasoline Subarus.

Representative Subaru models and their estimated fuel economy

Here are illustrative EPA-style figures for popular recent models, shown as approximate ranges to reflect year-to-year variations and different trims. Real-world results can differ based on driving conditions and configuration.

• Crosstrek Hybrid: about 6.5–7.0 L/100 km (36–38 mpg) combined.


• Crosstrek (non-hybrid, 2.0L): roughly 7.8–8.2 L/100 km (29–28 mpg) combined.


• Forester (2.5L, AWD): around 8.0–8.5 L/100 km (29–28 mpg) combined.


• Outback (2.5L, AWD): roughly 8.0–8.5 L/100 km (29–28 mpg) combined.


• Outback (2.4L turbo): typically about 9.0–11.0 L/100 km (26–21 mpg) combined, depending on configuration.


• WRX (2.0L turbo): approximately 8.5–9.5 L/100 km (28–25 mpg) combined.


• Legacy (2.5L, AWD): around 7.5–8.5 L/100 km (31–28 mpg) combined.


• Ascent (2.4L turbo, AWD): about 9.5–11.0 L/100 km (25–21 mpg) combined.

These figures illustrate the diversity within the Subaru lineup. Hybrids remain the standout for efficiency, while performance-focused trims and larger SUVs lean toward higher consumption. Always check the specific model year and trim for precise EPA estimates.

Practical tips to improve fuel economy

Whether you’re buying a Subaru or already own one, small changes can noticeably affect fuel use per 100 km. The tips below apply across most Subaru models and driving situations.

1. Drive smoothly: steady acceleration and gradual braking reduce energy use, especially with AWD systems that add weight.


2. Maintain proper tire pressure: under-inflated tires increase rolling resistance and fuel consumption.


3. Lighten the load: remove excess roof racks and unnecessary cargo to improve aerodynamics and efficiency.


4. Use cruise control on highways when conditions permit to maintain consistent speed.


5. Plan efficient routes: combine trips and avoid peak congestion when possible to reduce stop-and-go driving.


6. Use climate controls wisely: preconditioning the cabin while parked and using seat heaters rather than full A/C can save fuel, especially in stop-and-go traffic.


7. Keep up with maintenance: regular oil changes, air filter replacements, and timely spark-plug service help sustain optimal efficiency.

Adopting these practices can help real-world fuel economy align more closely with EPA estimates, regardless of model.

Summary

In short, a Subaru’s fuel use per 100 km varies by model and drivetrain. Most gasoline Subarus hover around 7.5–9.0 L/100 km (26–31 mpg) in mixed conditions, with the Crosstrek Hybrid pulling ahead at about 6.5–7.0 L/100 km (36–38 mpg). For precise numbers, check the specific model-year and trim’s EPA rating. With mindful driving and proper maintenance, drivers can maximize efficiency across the lineup.

Which car gets 70 mpg?

Several hybrid and diesel cars can achieve around 70 mpg, though it's often an official rating and can vary in real-world driving. Examples include the Vauxhall Corsa with a 1.5-litre turbo diesel engine, which can get up to 70.6 mpg, and various hybrid models, including some versions of the Hyundai Elantra Hybrid and Toyota Prius, which can reach this level under ideal conditions.
 
Examples of cars with around 70 mpg

• Vauxhall Corsa (1.5-litre turbo diesel): Can achieve up to 70.6 mpg, making it one of the most fuel-efficient diesel cars available. 
• Hyundai Elantra Hybrid: Early models were advertised with a claimed 70 mpg combined fuel economy. 
• Toyota Prius: Various models can get close to 70 mpg, especially older non-plug-in hybrids which are cheaper on the used market. Plug-in hybrid versions can also run on electric power for short distances. 
• Hyundai Ioniq Hybrid: Can achieve around 59 mpg combined. 

Important considerations

• Official vs. real-world MPG: The 70 mpg figure is often an official rating that is achieved under specific testing conditions, and your real-world mileage may be lower or higher depending on your driving habits, the vehicle's condition, and road conditions. 
• Hybrid vs. diesel: Both hybrid and diesel cars can achieve high MPG, but hybrids have the added benefit of electric-only driving for short distances, while some diesels can have higher upfront costs but offer impressive fuel economy on long-distance journeys. 
• Age and model: Some of the models with the highest MPG ratings are older, so be sure to research specific model years when shopping. 
• Type of driving: While hybrids and diesels can be very efficient, their fuel economy can vary significantly depending on whether you are driving in the city or on the highway. 

What is a good fuel economy per 100km?

A good fuel economy is generally considered to be below 6 L/100km for a passenger car, while 8 L/100km or less is excellent for SUVs and trucks. Lower numbers indicate better fuel efficiency, meaning the vehicle uses less fuel to travel the same distance. For example, a small car might get 5-6 L/100km, while a medium SUV could be considered good at 7-9 L/100km.
 
What is considered good fuel economy

Vehicle Type	Good Fuel Economy (L/100km)
Small Car / Hybrid	Below 6 L/100km
Medium SUV	Around 8 L/100km or less
Truck	Below 12 L/100km
Plug-in Hybrid	0-5 L/100km

What is considered average or poor

• Average passenger car: 8-10 L/100km
• Average larger SUV/truck: 12-14 L/100km
• Poor fuel economy: Anything over 12 L/100km is generally considered poor. 

Factors that influence fuel economy

• Vehicle size and type: Smaller, lighter vehicles and hybrids are more efficient. 
• Driving style: Aggressive acceleration, hard braking, and high speeds decrease fuel efficiency. 
• Driving conditions: City driving with lots of stops and starts is less efficient than consistent highway driving. 
• Vehicle maintenance: A well-maintained engine will be more efficient. 

Why is Subaru's fuel consumption so high?

The reason is because the motor was designed in the 80s so it's ancient technology, and it's a low compression motor so it doesn't burn fuel efficiently at light throttle. It's also a very heavy car at nearly 3500lbs. All this combines to give it poor gas mileage and dated performance numbers.
