The 2022 Toyota Prius Prime gets 54 MPG combined, a number central to this plug-in hybrid. This isn’t a vehicle sought after for performance, styling, or luxury. Prius Prime shoppers want exceptional fuel efficiency and are committed to minimizing their environmental impact, often making it their top priority. They’re willing to accept the Prius Prime’s quirks, and it does have some, because of the significant fuel savings.

City and highway performance

The EPA numbers show how the Prius Prime performs in different driving conditions. It achieves 55 MPG in the city and 53 MPG on the highway. This similarity in fuel economy highlights a key trait of many hybrids: they excel in stop-and-go traffic due to regenerative braking. The Prius Prime captures energy when decelerating and recharges the battery, reducing the need to use the gasoline engine. While the drop to 53 MPG on the highway might seem surprising, aerodynamics are important for fuel efficiency at higher speeds, and the Prius Prime’s shape is designed to reduce drag. For those with consistent routes, the consistency in fuel economy is a plus.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Toyota Prius Prime is $800. This is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Individual fuel costs will change depending on local gas prices and driving habits, but this $800 estimate is a useful benchmark for potential buyers. It shows the savings possible compared to a conventional gasoline-powered vehicle, which can easily cost double or triple that amount to fuel each year. Factor that against all all Toyota fuel economy data and you see the value argument.

Real-world expectations

While the EPA estimates are a guide, real-world fuel economy differs. The Prius Prime has an advantage over the standard Prius because it can be plugged in. Drivers who regularly plug in their Prius Prime and mainly drive short distances can achieve higher fuel economy, even exceeding the EPA estimates, by driving mostly on electric power. However, those who rarely plug in and primarily drive long distances on the highway might see fuel economy closer to the non-Prime Prius. Driving style, climate, and terrain affect the final MPG figures. Consider your own driving patterns to accurately predict your fuel savings. It’s also a good idea to look at PRIUS MPG across all years.

How it compares

The Prius Prime is unique in the car market. Compared to the standard Toyota Prius, which gets 56 MPG combined in its LE trim, the Prime offers plug-in capability for more electric driving. The Hyundai Ioniq Plug-In Hybrid, rated at 52 MPG combined, is a direct competitor. The Honda Insight, a hybrid sedan, gets 52 MPG combined, making it worth considering for those who want a more traditional sedan shape and driving experience. Fully electric vehicles like the Nissan LEAF offer zero-emission driving, but they require adjusting to charging infrastructure and range. The Prius Prime hits a sweet spot: high fuel economy and the flexibility of a gasoline engine for longer trips.

Tips to maximize efficiency

Charging often is important for maximizing the Prius Prime’s fuel efficiency. Plug in the vehicle after each trip if you can, even for short errands. This keeps the battery charged, allowing for more electric driving and less gasoline use. Setting a charging schedule to match off-peak electricity rates can lower your running costs.

Accelerate and brake gently to maximize fuel efficiency in any hybrid vehicle, including the Prius Prime. Avoid hard acceleration, which forces the gasoline engine to start. Anticipate traffic and brake gradually, allowing the regenerative braking system to capture energy and recharge the battery. Using the “B” mode on the transmission also increases regenerative braking.

Check your tire pressure. Properly inflated tires reduce rolling resistance. While a small improvement on its own, it makes a difference over time. Check your tire pressure regularly and keep it at the recommended level, which is on the sticker inside the driver’s side doorjamb.

Reduce accessory use, whether operating in EV or HEV mode. Air conditioning strains the system, so does rapid defrosting of front and rear windows. When you need them to improve visibility or comfort, use them sparingly. Plan your trips and adjust your schedule to avoid traveling at times that require using them a lot.
