23 MPG combined isn’t going to win any fuel economy awards, but for the 2018 Dodge Challenger V6, it’s a perfectly reasonable trade-off. This isn’t a hybrid or an economy car; it’s a stylish, comfortable coupe with enough power to be genuinely fun and a healthy dose of retro swagger. Consider it a modern muscle car with manners, and suddenly that fuel consumption figure makes a lot of sense, especially when you examine CHALLENGER MPG across all years. Owners aren’t prioritizing efficiency above all else; they want the look, the feel, and the sound of a Challenger, and the V6 delivers all of that at a more accessible price point.

City and highway performance

The EPA estimates 19 MPG city and 30 MPG highway for the 2018 Dodge Challenger with the 3.6L V6 and 8-speed automatic transmission. That 30 MPG highway figure is particularly important because it shows that while the Challenger can certainly deliver thrilling performance, it’s also capable of relaxed and relatively efficient cruising when you’re not pushing it. The 19 MPG city figure is less flattering, reflecting the engine’s need to work harder in stop-and-go traffic and the Challenger’s overall weight. Drivers who spend most of their time in urban environments will likely see a dip in their overall fuel economy.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2018 Dodge Challenger 3.6L V6 is $1,900. This figure is based on driving 15,000 miles per year and using national average fuel prices. Remember that this is just an estimate, and your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local fuel prices. It provides a useful benchmark for comparing the Challenger’s fuel consumption to other vehicles in its class. Premium fuel is not required, helping to keep those costs down.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy often differs. Challenger owners report numbers somewhat below the official figures, particularly if they drive aggressively. Spirited acceleration, frequent short trips, and prolonged idling can all negatively impact fuel efficiency. However, drivers who focus on smooth acceleration, maintain a steady speed on the highway, and minimize idling can often get closer to the EPA estimates, or even exceed them on long trips.

How it compares

Compared to other sporty coupes, the 2018 Dodge Challenger 3.6L V6’s fuel economy is competitive, but not the best. The Ford Mustang EcoBoost, for example, is rated at 25 MPG combined, offering a slight advantage in fuel efficiency, but a different driving experience. The Nissan 370Z, though offering a more raw and sporty feel, achieves around 22 MPG combined, putting it close to the Challenger. The Chevrolet Camaro with its base turbocharged engine also matches the Mustang’s 25 MPG combined. The Challenger’s appeal lies in its unique blend of muscle car styling, comfortable interior, and accessible performance, making the fuel economy a secondary consideration for many buyers. Potential owners comparing all Dodge fuel economy data should consider their individual needs and priorities.

Tips to maximize efficiency

The 8-speed automatic transmission in the 2018 Challenger V6 is key to maximizing fuel economy. Let the transmission do its job and shift smoothly. Avoid aggressive acceleration unless you truly need it, as this will force the engine to work harder and consume more fuel. Using cruise control on the highway helps maintain a steady speed and prevents unnecessary fluctuations in fuel consumption.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which in turn reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the sticker inside the driver’s side door jamb. This simple step can make a noticeable difference over time.

Regular maintenance is critical for optimal fuel efficiency. Keep your engine properly tuned, and change the air filter according to the manufacturer’s recommendations. A clean air filter ensures that the engine receives adequate airflow, which is essential for efficient combustion. Using the recommended grade of motor oil is also important for minimizing friction within the engine.

Reduce unnecessary weight in the vehicle. Carrying extra cargo adds weight, which increases the amount of energy required to move the car. Remove any items from the trunk or backseat that you don’t need to carry regularly. This is particularly relevant for a car like the Challenger, which is already a relatively heavy vehicle.

Limit idling time. Idling gets you zero miles per gallon. If you’re going to be stopped for more than a minute or two, it’s more efficient to turn off the engine. Modern engines are designed to restart quickly and easily, so you don’t need to worry about excessive wear and tear from frequent restarts.
