Our Prius Prime long-term test car was plugged in and ready for its usual around-town electric car duty, something it did with ease every day with its up to 44 mile range exclusively on batteries. It had been a while since we had to go beyond those all-electric miles and take advantage of the Prime’s long-range capabilities as a hybrid. Yep. A road trip was calling.
This time we’re heading out from Green Car Journal’s headquarters in San Luis Obispo on California’s Central Coast, up the Cuesta Grade, and through bucolic Paso Robles, one of the most important wine regions in California. But it isn’t wine we’re focused on this trip so we continue northbound amid wide-open countryside dotted with the occasional small city beckoning those needing fuel or food.
Our destination 145 miles ahead is the picturesque Monterey Peninsula, home of charming Carmel-by-the Sea, the laid-back Carmel Valley, and historic Monterey with its Fisherman’s Wharf and Cannery Row of Steinbeck lore. This is an area steeped in history that beckons one to experience and explore, with one of its highlights the dramatic 17 Mile Drive that winds along some of the most spectacular coastline on the planet. It’s no wonder that the Monterey Peninsula is an incredibly popular tourist destination that attracts visitors from all over the world.
Drawing our attention as auto enthusiasts is that the peninsula is the home of the annual Monterey Car Week, Pebble Beach Concourse de Elegance, The Quail Motorsport Gathering, and the Monterey Motorsports Reunion historic car races at nearby Raceway Laguna Seca. While this wasn’t our focus now, visiting Monterey in August provides some of the best auto enthusiast immersions possible anywhere. Beyond the week's many official gatherings, you'll find automotive eye candy in abundance plying the streets of Carmel-by-the-Sea and Cannery Row as classics and exotics show their stuff amid everyday life.
As the miles rolled by during our drive, we couldn't help but appreciate the accommodating features of our Prius Prime and how ideal it is for this, or really any, road trip. There were four of us this time – three adults and a child – with our Prius loaded with the gear and trappings required for a fun weekend getaway. As we made our way northbound it wasn’t lost on us that these days, a great majority of trips, local and long distance, are made in SUVs of one stripe or another. We've done plenty of that and the sheer number of these on the road during our drive illustrated their popularity. But we have a great interest in efficiency and the capabilities that family sedans and hatchbacks with a smaller footprint continue to bring to the highway. The Prius Prime is a poster child of this efficiency and functionality.
Speaking of efficiency, one can't help but be impressed with how frugal this Toyota plug-in hybrid is with a gallon of gas. While numbers can vary depending on speed, terrain, and driving style, it's a given that more often than not we're seeing 50-plus mpg displayed on our instrument panel, including on this trip. That's a testiment to the Prius Prime's newest-generation Hybrid Synergy Drive. This powertrain combines a 2.0-liter engine, 151 horsepower motor-generator, and 13 kWh battery pack to not only deliver this high level of efficiency, but welcome performance as well with its overall 220 horsepower. While we appreciate the ability to plug-in during travels to enable a degree of all-electric driving at an EPA rated 127 MPGe, we only did that before leaving home and upon our return from this quick weekend journey.
On our list of high points for this trip was stopping by Mission San Carlos Borromeo de Carmelo, also known as Carmel Mission, in Carmel Valley. The second of 21 missions established from 1769 to 1823 by Franciscan missionaries led by Padre Junipero Serra, the mission is fully restored and an important touchstone in the region’s history. We’ve traveled to all 21 missions in the California Mission System over the years and a stop at Carmel Mission was a must during this trip.
No trip to the Monterey Peninsula is complete without spending time exploring the many distinctive shops and eateries in quaint Carmel-by-the-Sea. There's no doubt this is an art town given the sheer number of art galleries present along its charming streets. Pastries? Sure. Unique and hand-made gifts? Absolutely, at an endless sea of shops. And dining experiences? There's no shortage to choose from, but you won't want to miss breakfast at Village Corner California Bistro or lunch at Clint Eastwood's Hog's Breath Inn.
There are so many activities to experience here that time isn’t on your side. A weekend getaway is always fun but additional days afford the luxury of taking in all the area has to offer. No matter how long a trip to this Central Coast jewel, you can't come to the Monterey Peninsula without a visit to the truly impressive Monterey Bay Aquarium, located on Cannery Row. That's how it was with us considering we had a five year-old in tow who patiently tagged along during our shopping in Carmel-by-the-Sea, visits to historic sites, and explorations of other points of interest. A visit here is truly a treat for kids and adults alike and a great way to cap off a Monterey Bay vacation.
The latest generation Prius Prime – now rebadged as the Prius Plug-In Hybrid for 2025 – has been a welcome change of pace from Toyota. Sleek, stylish, and unexpectedly fast, the debut of an all-new model in 2023 presented an unexpected departure from the pedestrian Prius stylings of old.
Don’t get us wrong: The Prius has always been a game-changer in its own right with its supreme efficiency and leading eco-consciousness. But it never was a model appealing to performance-focused auto enthusiasts or one drawing admiring looks from passers-by…until now.
Since we began our long-term test of a fifth generation Prius Prime XSE last year, we’ve found this hatchback’s overall driving experience to be just as we had hoped. While today’s Prime is similar to the previous generation with notable high efficiency and plug-in capability, there’s a world of difference that makes the model so much more compelling. First, there’s the styling. We don’t know what prompted Toyota to let its designers have at it with such a huge change in looks and an all-new ethos, but we do know what to say in response: “Thank you very much…great job!”
Beyond its now compelling appearance is the model’s newfound embrace of performance. The previous Prime used a 1.8-liter four-cylinder delivering 95 horsepower, augmented by its electric motor’s 71 horsepower. The new Prime ups the ante by nearly 100 horsepower, delivered by a 150 hp 2.0-liter engine and 161 hp electric motor. This extra power is immediately noticed and appreciated, especially during freeway driving when changing lanes and overtaking slower cars is a necessity. Plus, the extended range provided by the larger 13.6 kWh battery in this plug-in hybrid is a welcome addition, increasing electric driving range from some 25 miles to 44 miles of all-electric driving. EPA estimates the Prime XSE at an overall driving range of about 550 miles.
One of the things that often fascinates drivers is a plug-in hybrid’s ability to seamlessly blend the efficiencies of battery and hybrid drive during journeys beyond the Prime’s all-electric range. For example, on a recent roundtrip 600 mile drive down the California coast on the southbound 101 freeway, we experienced a peak combined 86.9 mpg during one segment of the trip after starting with a full charge. On the drive back and without having a charged battery, our mpg readings settled closer to 45 mpg while experiencing bouts of traffic and construction on the various highways heading back north.
On another 200 mile round-trip drive from California’s Central Coast to the Central Valley, our fuel economy remained an impressively stable 55 mpg on hybrid power alone. At times, driving conditions had degraded from a relatively clear evening and slowly gave way to dense fog. Despite the heavy fog conditions, the robust suite of technologies provided by Toyota’s Safety Sense 3.0 helped ensure a smooth and safe experience during this challenging drive with low visibility.
The assistive driving features on the Prius Prime have been indispensable on many drives taken during the past year. While many Toyota Safety Sense 3.0 systems are available, our favorites would be Proactive Driving Assist and the Traffic Jam Assist.
Adaptive cruise control typically feels more reactive than proactive, but the addition of features with the appropriately named Proactive Driving Assist helps make unfamiliar roads feel safer. Proactive Driving Assist complements Dynamic Radar Cruise Control and is a key component of the Toyota Safety Sense 3.0. Working in tandem with this system means that PDA is able to assist with breaking into curves, provide steering input to help keep you centered in the lane even during mild corners, and provide obstacle anticipation assist all at once.
Traffic Jam Assist is indispensable during drives with stop and go traffic, which was common during our drive down the California coast as we approached larger metro areas. This feature does require Toyota’s Drive Connect subscription to use, but I did find it worthwhile if stop and go traffic is a common experience. TJA operates at typical traffic jam speeds under 25 mpg and engages a host of other features, including hands free steering, acceleration, and braking during heavy traffic. Recording is also an option with Traffic Jam Assist as an added (but hopefully unneeded) feature during bumper to bumper traffic where collisions are statistically more likely. Recording is implemented during crash or crash-like events.
These driver assist features, in addition to the entire Toyota Safety Sense 3.0 suite, add comfort and an enhanced sense of safety during our frequent drives. Overall, longer drives feel less arduous with Prius Prime, which means we can focus on enjoying the road ahead and being behind the wheel of an entirely satisfying vehicle that’s comfortable and a joy to drive.
Green Car Journal has closely followed the evolution of the Toyota Prius since our early hands-on experience at Toyota’s Arizona Proving Grounds in mid-1997. Here, we piloted a Toyota Corona test mule powered by an exotic gas-electric powerplant concept that was unlike anything we had driven before. Little did we know that this test car’s Toyota Hybrid System would make its way in production form to the automaker’s all-new Prius, a model that debuted later that year at COP 3, the third United Nations climate conference. This is where the landmark Kyoto Protocol international treaty was adopted to mitigate greenhouse gases and climate change.
The Prius was there to make a statement that Toyota recognized the environmental challenges ahead and was prepared to lead. Prius sales began in Japan in 1997 and expanded worldwide in 2000. The rest is history. In the 27 years since the Prius was introduced, this hybrid has stayed true to its original mission as a model of high efficiency and low carbon emissions. It has shape-shifted over time, starting out as a quirky subcompact sedan and then morphing into a hatchback with a distinctive and easily-recognizable profile.
Now in its all-new fifth generation, Toyota’s Prius is a true game changer presenting as a wondrous liftback with a whole new outlook that far transcends eco consciousness, though that is still the core of its being. Today’s Prius is now sleek and visually compelling, extraordinarily fuel efficient at up to 57 combined mpg, and delivers surprising levels of performance for an eco-champion priced at just $27,950.
For an additional five grand the model’s plug-in hybrid variant, Prius Prime, features all this along with a more powerful 13 kWh lithium-ion battery that brings an EPA estimated 45 miles of electric driving and up to 600 miles of overall range. Along with its admirable EPA estimated 52 combined mpg as a hybrid, Prime achieves up to 127 MPGe when running on its batteries.
Prius Prime’s considerable battery electric range makes it the ideal electric vehicle for a great many who wish to drive zero emission every day, but also want the ability to tackle longer trips seamlessly. This characteristic, and so many others that elevate the model above its peers, distinguished Toyota’s Prius Prime as Green Car Journal’s 2024 Green Car of the Year®.
Performance in a traditional sense, like quick acceleration and impressive driving dynamics, has never been expected of a Prius. That wasn’t its mission. This changes in a big way with the new Prius presenting as a driver’s car, a model that speaks to car enthusiasts who value appealing style and a fun-to-drive nature alongside environmental performance. The new Prius Prime’s 220 system horsepower, delivered by a 2.0-liter engine and 161 hp electric motor-generator, changes the performance equation with nearly 100 more horsepower and a third greater torque than the previous generation Prime. That extra power is a big deal and drivers will appreciate Prius Prime’s surprising ability to sprint from 0-60 mph in just 6.6 seconds.
Greater performance aside, the most noticeable change in the new Prius is clearly its attention-grabbing, smoothly sculpted design. We know this first-hand. Over the past few months, we’ve spent significant time behind the wheel of an uplevel ($39,670) Prius Prime XSE long-term test vehicle equipped with this model’s full complement of advanced electronics and a cabin smartly upholstered in leatherlike SofTex. Inevitably, we get looks, questions, and overt signs of appreciation from a great diversity of people during our drives, many of them drivers of earlier Prius models and others who simply love the car’s forward-leaning and distinctive look.
We get it. The new Prius exudes a sporty appearance with its low roofline and sweeping aerodynamic profile, lending homage to the Prius of old while transforming its look into something more compelling. Once attention moves beyond the car’s most noticeable and eye-catching feature, there’s plenty inside to appreciate as well. Here, one finds a comfortable and functional cabin featuring a pleasing balance of tech, comfort, and style, with a distinctive instrument panel design that takes its cues from Toyota’s bZ4X electric car.
We’ll be sharing our experiences of daily life with the Prius Prime in the months ahead, and no doubt, more stories of interactions with others who find the all-new Prius as compelling as we do.
Toyota’s 2017 Prius Prime aims to fill the needs of drivers who love the efficiency of the ubiquitous Prius but want the added benefit of a plug. As is the case with most hybrids, all-electric drive in the conventional Prius hybrid is limited to very short stretches with light pressure on the accelerator, otherwise it’s running on gasoline-electric hybrid power. The Prius Prime changes this with truly usable battery electric range before resorting back to hybrid propulsion.
Prime is a significant advance for Toyota as the company seeks to establish the highest conceivable standard for a plug-in hybrid, all packaged in edgy sci-fi styling. Think Blade Runner and you’re not far off, but in a clean Zen environment. Three distinct models of the Prius Prime are offered to fit varying tastes, including the Prime Plus at $27,100, the Prime Premium at $28,800, and the Prime Advanced at $33,100.
All Prime models share their silhouette with the Prius Hatchback but with unique front and rear end treatments. Prime is also 6.5 inches longer and just a bit lower and wider than the standard Prius model. To achieve increased front and rear head room, engineers lowered placement of the gasoline engine, electric motor, and seats. An additional benefit Toyota designers targeted was slippery aerodynamics, which they achieved with a coefficient of drag of just 0.25 – lower than most sports cars. Less wind resistance is an important element in achieving Prime’s exceptional fuel efficiency of 54 combined mpg as a hybrid and 133 MPGe when running on battery power. With an estimated driving range of 640 miles, Prime will outrun most anything for distance. EPA estimates an all-electric range of up to 25 miles.
We spent time behind the wheel of a fully-equipped Prime Advanced model on twisty mountain roads and highways to get a feel for Toyota’s new plug-in hybrid. Our test drive included stretches of high speed curves with little traffic, where we found the Prime Advanced doing quite well with good mid-range power while passing on two-lane roads. We’ve driven a friend’s first-generation 2016 Prius Plug-in Hybrid regularly over the past year and found it very efficient, but mundane and cumbersome on our own mountain road. A few fast turns into our drive instilled much more confidence in Toyota’s latest plug-in hybrid as we continued increasing our speed in turns.
The Prime’s major improvement in handling stems from a much more grounded feeling in turns, a nod to the Prime’s use of independent McPherson strut front suspension and double-wishbone rear suspension, with stabilizer bars front and rear. This is what some of the better-handling sports car utilize for their superior driving characteristics. Another significant change to enhance handling was moving the car’s 287 pound lithium-ion battery to the rear, with the weight transfer making a big difference in balanced handling. The only thing that holds you back from driving faster is the squeal of tires that are primarily designed for fuel economy.
Prime uses all-season P195/65/R15 tires mounted on 6.5J X 15 inch 5-spoke aluminum wheels. There are no optional wheel or tire choices and no spare. For tire repairs there is a repair kit and three years of 24-hour roadside assistance at no charge. Prime’s basic warranty is 36 month/36,000 miles with an additional 60 months covering the powertrain, with no mileage limitations. Hybrid-related components including the HV battery and modules are covered for 8 years/100,000 miles.
Toyota’s Hybrid Synergy Drive powers all Prius Prime models using a dual motor drive. This dual motor capability did not come with the addition of a second drive motor, but rather repurposing the drivetrain’s motor-generator (MG1) for additional use. In this configuration, a one-way clutch engages both MG1 and the car’s primary electric drive motor (MG2) for motive force, the first time MG1 has been used in this way. During deceleration, regenerative braking recaptures electrical energy through MG1 and stores this energy in the battery for later use. Energy is supplied to the motors via an 8.8 kWh lithium-ion battery pack. The gasoline engine used in this hybrid powertrain is a 1.8 liter, 95 horsepower Atkinson-cycle four- cylinder. Combined, the engine and motors deliver 121 net system horsepower.
For some, the best new feature will be changes in charging requirements. While the Prime’s 8.8kWh battery delivers over double the energy of the previous Prius Plug-In’s battery pack, no special wall charger is needed. Just plug it into a standard 120-volt household outlet and in less than 5 1/2 hours you’ll have a full charge. Toyota recommends a dedicated 15A GF1 outlet for this. Faster charging in under two hours is achieved using a public charger or a 240-volt home charger, if desired. Prius Prime apps can manage charging, locate charge stations, set climate control, and handle numerous other functions that take advantage of the Prius Prime’s connected capabilities.
Different operating modes can be selected. EV Auto Mode will automatically rely on electric capability in urban driving and during short trips. Under certain driving conditions such as negotiating steep hills, Prime’s gas engine will kick in to provide additional power. Selecting Hybrid Mode uses the gas engine for primary drive force with supplemental power from the electric motor. Power is transmitted via a planetary-type continuously variable transmission.
The most distinctive styling elements of Prime are its quad LED headlights that give this car its futurist look. These automatically adjust brightness to its environment and oncoming cars. Without a doubt, a Prime will always be readily identifiable at night given its full-width LED rear light panel that follows the shape of the double-wave rear window and spoiler. In fact, the first time you see a Prime on the road at night an immediate impression might be that of a new Lamborghini…the taillights have that kind of styling impact.
Contributing to the Prius Prime’s overall light weight of 3,375 pounds is a rear hatch made from carbon fiber. This superior strength material is usually only found on exotic or race cars due to its expense. In this application it is used for lightweighting purposes and to make opening and closing the hatch effortless. Rear visibility is enhanced by a full-width glass panel and standard backup camera.
All Prime models feature a four-seat layout with a center console front and rear, with 60/40 folding rear seats. The front console has a handy wireless charging pad for Q-i compatible devices. Auxiliary 12-volt power outlets are provided up front and in the rear, with a USB 2.0 port for iPod connectivity and control standard. The shiny white plastic used for the console has a Star Wars trooper look to it and may be too bright for some tastes. A 4.2-inch gauge panel mounted above the dash is considerably easier to read in daylight than that of the previous model. A heads-up display is available.
The most obvious interior feature is Prime’s optional 11.6-inch tablet-like HD multimedia screen that’s mounted vertically in Premium and Advanced models. A standard Entune multimedia system provides audio, navigation, and an App Suite. Suffice to say if it’s on the market, Prime has bundled it...unless you want to play CDs. Apparently there is no place for CDs in the future. Audiophiles will be particularly pleased with the Prime Advanced model since it includes JBL audio with 10 speakers and delivers an exceptional concert hall experience.
For those who find parking a challenge there’s the Advanced model’s included Intelligent Clearance Sonar (ICS) with Intelligent Parking Assist (IPA). Once selected, the system’s sonar sizes up an available parking space and reverses the car into the space. Perpendicular spaces are also negotiated, plus it will also steer you out of a parallel spot.
The Prime's Safety Sense P list of standard safety features is as impressive as it is extensive. Prime bundles a Pre-Collision System with Pedestrian Detection and Automatic Braking, Lane Departure Alert and Steering Assist, Full-Speed Dynamic Radar Cruise Control with full stop technology, and Auto High Beams. The Advanced model adds Blind Spot Monitor and Rear Cross Traffic Alert. Also, there are eight airbags for additional driver and passenger safety.
Toyota is out to raise the standard by which plug-in hybrids are measured. They have done so with the Prius Prime by adding leading edge technology systems coupled to a powertrain that is a marvel of efficiency. Factoring in a price reduction in the thousands from the earlier generation Prius plug-in and an expanded 25 mile battery-only driving range, this Toyota model certainly holds appeal for Toyota Prius fans and new converts to a plug-in hybrid society.
Toyota has added ‘Prime’ to the branding of its second generation plug-in hybrid electric vehicle (PHEV) to emphasize it’s the most technologically advanced, best-equipped Prius ever. Prime is the first Toyota hybrid to feature a dual-mode generator drive system that enables the Hybrid Synergy Drive’s electric motor and generator to both provide power for maximum acceleration. A new 8.8 kWh lithium-ion battery pack delivers up to 22 miles of all-electric driving, double that of the first-generation plug-in Prius. Toyota estimates 120 MPGe or greater or the model, which is expected to be the highest MPGe rating of any PHEV.
Prime features an array of connected and advanced electronics systems including an available 11.6-inch HD multimedia screen. Prius Prime will start appearing in U.S. showrooms in late fall and will be available in all 50 states.
