We Recommend

The 2018 Toyota Prius Prime is all about convenience and comfort. The more you are willing to pay, the better features you get that will make your ride better and enjoyable.

About a thousand bucks costlier than the base model, it offers better and enhanced infotainment system with some additional perks.

2018 Toyota Prius Prime Engine and Performance

“The Toyota Prius Prime’s strong suit lies in its superb fuel efficiency and ability to switch from gas to electric power smoothly. Though handling is composed, it’s slow to accelerate, and it doesn’t have a very engaging ride.”- cars.usnews

Engine and Transmission

Though the 2018 Toyota Prius Prime flaunts to have the best engine in its competition, the performance is just the opposite. The latest avatar of Prius Prime delivers only 121 hp of power, which seems puny when compared with 139 hp offered by Hyundai’s Ioniq Hybrid and Kia Niro FE. Chevrolet Volt rules the power category with 149 hp.

Power 121 hp 139 hp 139 hp 149 hp
Torque 105 lb-ft 109 lb-ft 195 lb-ft 294 lb-ft

The torque capability of Prius Prime further diminishes its performance with a mere value of 105 lb.-ft. Hyundai Ioniq Hybrid is nothing much greater than Prius Prime with 109 lb.-ft. of torque. While the Niro FE delivers a powerful torque of 195 lb.-ft. even that is put to shame by the 294 lb.-ft. the amount of torque delivered by Chevrolet’s Volt.


Another downer for the Toyota Prius Prime is its poor acceleration. Kia Niro FE takes about 8.6 seconds to reach 60 MPH from nothing. While Hyundai Ioniq Hybrid requires 8.1 seconds to accomplish the same feat, Volt offers a superior acceleration with a time slot of mere 7.8 seconds. The 2018 Toyota Prius Prime is much behind the competition with 10.2 seconds.

N/A 3.2 3.5 1.3

While Chevrolet Volt takes only 15.9 seconds to cover a quarter-mile, Ioniq Hybrid and Niro FE take almost 17 seconds. Again, Toyota Prius Prime lags behind by taking 17.7 seconds to traverse a quarter-mile.

Ride and Handling

Handling has always been a pleasing aspect of the Toyota Prius Prime, to which the latest iteration is no exception. Since all three trims work on the same level of powertrain and battery, the handling and steering experience is same on all of them. The wheel is soft as well as the braking system is a breeze.


Braking capability of the latest iteration of Toyota Prius Prime is yet another area requiring work, but not completely. Even though supporting a curb weight of 3365 lbs., it comes to a halt from 60 MPH to 0 MPH at a distance of 125 feet. This is much better than that offered by lighter Ioniq Hybrid and Kia Niro FE.

Curb weight(lbs) 3365 2996 3106 3543
60-0 MPH 125 124 138 120

Once again, Chevrolet Volt emerges victorious with a halting distance of 120 feet, best among the competition. So, the braking system of Prius Prime is average, almost a relief compared to the acceleration offered by the same.

Fuel Economy

Undoubtedly, the biggest advantage of going for 2018 Toyota Prius Prime is the impressive combined mileage of 54 mpg-e. It is superior to that offered by the Kia Niro FE and Chevrolet Volt, 50 and 42 respectively.

“There’s no risk of the 2018 Toyota Prius Prime getting lost in a crowded mall parking lot. It looks like something out of a sci-fi movie. It wouldn’t look out of place driving around Hill Valley’s town center in Back to the Future Part II.”- Kelley Blue Book

Dimension and Weight

Neither the curb weight nor the ground clearance is good, which are 3365 lbs. and 4.8 inches, respectively. Hyundai Ioniq Hybrid, with 2996 lbs., and Kia Niro FE, with 3106 lbs., are much lighter than Prius Prime. However, Chevrolet Volt is the heaviest with 3543 lbs. of curb weight.

Exterior Features

There aren’t much to the exteriors of the 2018 Toyota Prius Prime as with its interiors. It seems to flaunt a typical chrome build with not much mulled over design. Nonetheless, here are some exterior feats of the hybrid car:

  • Toyota Prius Prime flaunts to have a basic outer design. It isn’t something to brag about but a relief when compared with the appearance of its sibling Prius
  • Dual-wave Rear Glass Design
  • Carbon-fiber Reinforced Polymer Rear Hatch
  • Washer-Linked Variable Intermittent Windshield Wipers

Seating and Comfort

2018 Toyota Prius Prime is comfortable, no doubt about that. However, it can accommodate only 4 passengers, which is lowest in the competition. Ioniq Hybrid, Volt and Kia Niro FE, all of them offer a passenger capacity of 5. In the front the headroom is average, shoulder room is smaller and legroom, 43.2 inches, is the larger.

At the back seat, the latest iteration of Prius Prime flaunts to have 37.2 inches, 53 inches and 33.4 inches of headroom, shoulder room and legroom, respectively. None of them is impressive, yet acceptable at its best.

The navigation system is average, while non-navigation functions are above average. Connecting and using smartphone apps is easier, though not completely convenient. Physical knobs, as well as the climate controls, are a delight and relief to use.

Interior Features

Prius Prime develops over the Prius with a pleasing style and a larger 8.8-kWh lithium-ion battery pack. Interiors of all the 3 trims are almost the same. Seat coverings differ for each trim option though. On the inside, the 2018 Toyota Prius Prime packs:

  • The seats are designed while keeping comfort in mind. Each of the doors has soft-touch panels and the dashboard is made from rubberized plastic that adds to the overall interior aesthetics of the ride
  • Bigger and better 11.6-inch screen is available in the Premium and Advanced trims
  • Exposed carbon-fiber weave is built along the edges of the hatch, which looks more than good

2018 Toyota Prius Prime Head-to-Head Competition Check

Chevrolet Volt

Chevrolet’s Volt is a beast in terms of power and torque, which are 149 hp and 294 lb.-ft., respectively. Moreover, it has the best acceleration in the competition. It takes only 7.8 seconds for the ride to hit the 60 MPH mark from 0. CO2 emissions are also lowest in the competition with an emission value of mere 1.3.

The biggest downer for the Chevrolet Volt is the hefty price-tag of $34,095. Also, it is the bulkiest car in the competition with a curb weight of 3543 lbs. If that’s not enough then adding all these facts with the poor fuel economy of 42 makes Volt a disastrous choice to make.

Hyundai Ioniq Hybrid (Blue)

The biggest perk of Hyundai Ioniq Hybrid is its inexpensive price-tag of $22,200, which is the least among the competition. It delivers a fair performance with its 1.6L GDI DOHC 16-Valve Inline 4-cylinder engine. Acceleration is good with 8.1 seconds for hitting 60 MPH from nothing. Fuel economy of 58 mpg-e is the most impressive in the competition.

Ground clearance isn’t impressive at 5.3 inches, still better than that offered by the Toyota Prius Prime. The Ioniq Hybrid takes 16.8 seconds to cover quarter-mile, which is only better than the Prius Prime. Torque is low at 109 lb.-ft., much behind than the Niro FE and Volt.

Kia Niro FE

Priced at $23,340, Kai Niro FE is a great option for those looking for a powerful ride. It features a 1.6L 4-cylinder and Full Parallel Hybrid System, capable of delivering 139 hp of power and 195 lb.-ft. of torque. Acceleration and handling are good. A fuel economy of 50 mpg-e is acceptable. Offers the best ground clearance of 6.3 inches among the competition.

Downsides of Kia Niro FE is led by 138 feet required for coming to a halt in emergencies. Moreover, it offers the most CO2 emission value of 3.5. 2nd row folded cargo volume is not available and front row legroom of 41.7 inches is the least among the competition.

Final Verdict for 2018 Toyota Prius Prime

Toyota Prius Prime offers one of the best fuel economies. It is an excellent option for those looking for a car that is capable of delivering the most economical performance in the city as well as on bustling highways. However, it falls short of the expectations of powerful acceleration and lightweight built.

Safety features of the car are impressive and of a high standard. If the 4-passenger only build is acceptable, then going for Toyota Prius Prime is a good thing to do. The infotainment is good but somewhat frustrating at times. However, if it is economy that matters the most then Toyota Prius Prime is worth the expense.
