A combined 23 MPG might not excite every car enthusiast, but most 2018 Subaru BRZ tS owners accept it. This car isn’t about saving fuel; it’s designed for driving pleasure, which the tS heightens. Buyers prioritize cornering and handling, and they’re willing to pay more at the pump for that.

City and highway performance

The EPA estimates the BRZ tS gets 20 MPG in the city and 27 MPG on the highway. The city figure shows stop-and-go traffic conditions, where the BRZ’s 2.0L engine works to accelerate its light body. The highway number shows that the BRZ can be efficient when cruising at a steady speed. The 6-speed manual transmission helps, letting drivers select higher gears to keep the engine at lower RPMs. Restraint is key, as a heavy foot will lower highway MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Subaru BRZ tS is $2,500. This is based on driving 15,000 miles per year and using the national average fuel price for premium unleaded gasoline, which the BRZ needs for its best performance. This cost can change depending on driving and fuel prices, and serves as a benchmark.

Real-world expectations

While the EPA provides a standard estimate, real-world fuel economy for the BRZ tS can change. Drivers who often drive hard, or engage in track days, should expect numbers closer to the city rating, or even lower. However, careful drivers who accelerate smoothly and maintain consistent speeds on the highway might see numbers close to, or slightly exceeding, the EPA’s 27 MPG estimate. This car rewards a light touch; drive it hard, and you won’t get close to the EPA’s number.

How it compares

The BRZ tS’s fuel economy sits in a niche compared to other sporty coupes. The Mazda MX-5 Miata, a competitor in terms of driving, gets a better 29 MPG combined with its manual transmission. The Miata prioritizes open-top driving and a relaxed feel. The Ford Mustang EcoBoost, with its turbocharged 2.3L engine, offers a more muscular 30 MPG combined, but lacks the BRZ’s focus on handling. Even all Subaru fuel economy data shows that fuel economy is not the top priority, with the brand favoring safety and capability. If you are interested in BRZ MPG across all years, that is also helpful to compare. BRZ buyers accept the trade-off: less fuel efficiency for a purer driving experience.

Tips to maximize efficiency

Drive smoothly. The BRZ’s engine rewards a light touch. Avoid fast acceleration and hard braking, to maintain speed, and maximize efficiency. Anticipate traffic and adjust your speed.

Tire inflation is important for fuel economy. Check your tire pressures and keep them at the recommended levels (on the doorjamb sticker). Underinflated tires create resistance, forcing the engine to work harder.

Consider using cruise control on long highway drives. This helps maintain a consistent speed and optimizes fuel consumption. Be mindful of hills, but cruise control can help maximize highway fuel economy.

Minimize idling, since idling consumes fuel. If you’ll be stopped for more than a minute, turn off the engine. This can make a difference over time, especially in city driving.

Avoid unnecessary modifications to the BRZ, which can affect fuel economy. Stick to factory specifications, unless modifications improve efficiency.
