The 2019 Volkswagen Jetta GLI gets 28 MPG combined, putting it in the running for drivers who want performance without sacrificing all fuel efficiency. The GLI prioritizes a fun, engaging driving experience. Buyers are performance-focused and have a daily commute, unwilling to accept an unexciting economy car. They value responsiveness and handling, but still need reasonable running costs. This MPG figure reflects that balance, accepting a slight penalty at the pump for a car that’s more rewarding to drive than a standard Jetta.

City and highway performance

The EPA estimates of 25 MPG in the city and 32 MPG on the highway for the 2019 Jetta GLI reflect its dual nature. The city figure acknowledges stop-and-go driving where the turbocharged 2.0L engine uses more fuel. The automatic transmission is programmed to shift smoothly and efficiently, but even in its most economical settings, it can’t completely overcome the engine’s thirst when accelerating. On the highway, however, the GLI is strong. At consistent speeds, the turbocharger requires less boost, and the engine settles into a more relaxed and efficient state, delivering highway MPG figures that are respectable for a sporty sedan.

Annual fuel cost

The officially stated annual fuel cost for the 2019 Volkswagen Jetta GLI is $1,550. This figure is calculated by the EPA using a formula that assumes 15,000 miles of driving per year, with approximately 55% of those miles driven in the city and 45% on the highway. The calculation also incorporates the national average fuel price for regular unleaded gasoline at the time the EPA testing was conducted. This figure should be viewed as a baseline; individual fuel costs will vary depending on driving habits, local fuel prices, and the grade of fuel used.

Real-world expectations

While EPA estimates provide a useful benchmark, real-world fuel economy can vary significantly based on individual driving habits and conditions. A driver who accelerates quickly and spends most of their time in city traffic can expect to see numbers closer to the low end of the EPA’s range, potentially even dipping slightly below 25 MPG. Conversely, someone who primarily commutes on the highway and practices smooth acceleration can likely achieve figures closer to or even slightly exceeding the 32 MPG highway estimate. Environmental factors like weather, tire inflation, and the use of accessories like air conditioning can also influence fuel economy.

How it compares

The 2019 Jetta GLI’s fuel economy compares well against its competitors. The Honda Civic Si, a rival known for its sporty character, achieves an EPA-estimated 26 MPG combined. The Hyundai Elantra Sport lands around 29 MPG combined, offering a slight edge in efficiency. Even some non-sport models like a Toyota Corolla hatch can slightly pull ahead near 31 MPG combined. Considering the GLI’s horsepower advantage and performance tuning, the minor fuel economy difference is acceptable to many buyers.

Tips to maximize efficiency

Avoid constantly accelerating as much as possible. The GLI is designed to be fun, but aggressive acceleration and frequent bursts of speed will significantly decrease fuel economy. Smooth acceleration will keep the turbocharger working less and save fuel, especially in city driving.

Check your tire pressure regularly. Under-inflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure for optimal fuel economy and handling.

Use cruise control on the highway whenever possible. Maintaining a consistent speed minimizes unnecessary acceleration and deceleration, leading to more efficient fuel consumption. Avoid abrupt speed changes, and anticipate traffic conditions to maintain a steady pace.

Minimize idling. Letting the engine idle for extended periods wastes fuel. If you anticipate being stopped for more than a minute or two, turn off the engine. Modern engines do not require a long warm-up period, so you can start driving gently almost immediately.
