30 MPG combined may not scream “fuel-sipping champion,” but for a large, comfortable, and technologically advanced sedan like the 2016 Acura RLX Hybrid, it’s a respectable figure. Acura isn’t aiming for Prius-level efficiency; they’re targeting a buyer who wants a smooth ride, a luxurious interior, and a strong V6 engine, while keeping fuel costs surprisingly low for the segment.
City and highway performance
The EPA estimates for the 2016 Acura RLX Hybrid are 28 MPG in the city and 31 MPG on the highway. This narrow difference between city and highway MPG shows the hybrid powertrain’s effectiveness in both driving environments. The electric motors help the 3.5L V6 during initial acceleration and low-speed cruising, reducing fuel consumption in stop-and-go traffic. The strong V6 doesn’t disappear at highway speeds. The RLX can easily cruise at 75 MPH while still getting impressive fuel economy. Many non-hybrid, smaller sedans struggle to match that 31 MPG highway figure.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2016 Acura RLX Hybrid is $1,950. This is based on driving 15,000 miles per year, with fuel prices reflecting national averages. Your actual fuel costs may vary depending on your driving habits, the type of roads you typically drive on, and local fuel prices. Aggressive driving or frequent trips to the mountains will likely increase that figure. Even at slightly higher fuel prices or mileage, the RLX Hybrid is still a fiscally responsible choice compared to its non-hybrid luxury competitors.

Real-world expectations
EPA estimates provide a useful baseline, but real-world fuel economy can change. Expect to see figures close to the EPA’s estimates with careful driving habits. Some owners report exceeding the 31 MPG highway estimate on long road trips, while others find the city MPG harder to achieve consistently if they accelerate hard often. The RLX Hybrid’s powertrain management system aims for optimal efficiency, but it cannot overcome inefficient driving practices. Weather, tire pressure, and the type of fuel you use can impact your MPG.
How it compares
When cross-shopping the 2016 Acura RLX Hybrid, knowing its fuel economy compared to competitor vehicles is critical. A similarly sized and equipped Lexus ES 300h, another strong contender in the hybrid luxury sedan segment, gets an EPA-rated 40 MPG combined , a better figure. A non-hybrid Acura RLX with the standard V6 engine gets around 23 MPG combined. The RLX Hybrid bridges the gap: it offers better fuel economy than the non-hybrid version, while still providing a more powerful and refined driving experience than some of its more efficiency-focused hybrid rivals. The buyer accepting the 30 MPG is trading fuel efficiency for a more engaging driving experience, which some people value. For RLX MPG across all years, you can browse our database.
Tips to maximize efficiency
Use the regenerative braking to your advantage. The RLX Hybrid uses regenerative braking to capture energy and recharge the battery when decelerating. Anticipate stops and gently ease off the accelerator, allowing the system to maximize energy recovery and minimize wear on your brake pads.
Pay attention to the power gauge. The RLX Hybrid features a power gauge in the instrument cluster that displays real-time energy usage. Keep the needle in the “charge” or “eco” zones as much as possible to optimize fuel efficiency. Avoid abrupt acceleration, which often sends the needle into the “power” zone, signaling increased fuel consumption.
Ensure proper tire inflation. Underinflated tires increase rolling resistance, which hurts fuel economy. Check your tire pressure regularly, ideally every two weeks, and inflate them to the recommended pressure listed on the sticker in your driver’s side doorjamb.
Minimize accessory usage. Power-hungry accessories like the air conditioning and heated seats can strain the electrical system and reduce fuel economy. Use them carefully, particularly during short trips where the engine may not have sufficient time to operate at its most efficient temperature. This is a great tip in EVs as well!
