Toyota’s Prius Prime saved me fuel cash however most likely not the atmosphere

I’ve at all times questioned what it could be prefer to personal a plug-in hybrid, and lately, destiny handed me that chance. On a latest journey to Vancouver, I rented a 2024 Toyota Prius Prime for almost two months — the best situation to check out North America’s hottest PHEV.

My expertise with the Prius Prime

Beforehand, the phrases “Prius” and “attractive” have been hardly ever utilized in the identical sentence. Nonetheless, I believe the wedge-shaped Prius Prime introduced for 2023 is a lot sexier than its frumpy predecessors. The glossy form additionally pierces the wind higher to enhance effectivity. It’s decrease to the bottom than earlier than, although, which might make entry powerful for taller or older folks.

I used to be snug within the Prius Prime as soon as seated, despite the fact that the supplies and choices aren’t fairly as luxurious as different PHEVs sold in the US. On two 10-hour freeway drives as much as northern Canada I by no means felt sore (or chilly) within the well-bolstered, heated seats. Nonetheless, visibility wasn’t the best because of the low seating place and thick entrance pillars that sometimes blocked my view of visitors.

With its wraparound sprint and 8-inch touchscreen, the inside within reason high-tech however to not the usual of some EVs I’ve tried lately. It got here with wi-fi CarPlay and Android Auto help that gave me seamless streaming leisure on lengthy freeway stretches. The motive force security options (lanekeeping, adaptive cruise, automated braking and extra) additionally boosted my confidence in Vancouver’s gnarly visitors. The Prius Prime doesn’t provide true one-pedal implementation, however it has a mode that’s near that.

With a two-liter 150 HP fuel motor and 161 HP electrical motor (web 220 HP combined), the 2024 (fifth era) Prius Prime has a whopping 100 extra horsepower than the earlier mannequin. The electrical drivetrain is equipped by a 13.6kWh battery (10.9kWH usable) that takes 4 hours to cost at 240 volts, or double that with 120-volt family electrical energy. Which means you may juice it totally in a single day, however it doesn’t have DC fast-charging for fast power-ups on longer journeys. The EPA electrical vary is 44 miles, 19 greater than the fourth-gen Prius.

It accelerated surprisingly nicely (from 0 to 60mph in 6.7 seconds) and was agile, however had a good quantity of physique roll because it’s not designed for the race observe. Nonetheless, contemplating the Prius’s repute as a staid hippie econobox, the brand new mannequin was downright sporty. I loved driving within the all-electric mode far more than the hybrid mode, although — it was quieter and smoother, with decrease noise ranges and vibration.

So, how far was I in a position to drive on that electrical motor alone? On the freeway at about 65 MPH, I eked out 30 miles and simply over 40 miles within the metropolis. On one journey, I drove from town heart to a suburb 30 miles away and made it there and partially again on a full cost. On one other voyage, I used to be in a position to drive forwards and backwards between the east- and west-most factors of Vancouver (13 miles) — a typical commute for a lot of city-dwellers — with a few quarter cost to spare.

With constant charging, my gasoline consumption over a two week interval (averaging 25 miles per day) was a few quarter of a tank or round $7.50. When it comes to electrical energy, I used almost 70.5kWh throughout that point at $.085/kWh, for a complete of $6. All instructed, I spent $13.50 for fuel and electrical energy over 350 miles of blended driving, so the Prius Prime was clearly low-cost to function.

For longer journeys, it’s nonetheless as cheap because it will get for a gasoline-powered car, because of the environment friendly ICE motor and hybrid system that’s among the many greatest within the business. With a full battery cost and tank, I set out on a 547-mile drive and travelled 470 miles earlier than stopping for fuel, with 1 / 4 tank to spare. That fill-up price round $25.

The true financial savings and the issue with plug-in hybrids

The timing for my take a look at of this automobile was supreme. In October, I noticed a European study concluding that PHEVs aren’t as economical as anticipated over a big pattern measurement. Engadget’s article about that stirred up some ardour amongst homeowners and potential consumers, so I wished to match my expertise with factors within the examine.

First, let’s see if a PHEV is price the additional cash in comparison with a daily hybrid. My calculations are for the typical US purchaser and don’t take state or federal clear air rebates into consideration.

Once I selected to hire a “compact” automobile, Avis assigned me a mid-range Prius Prime XSE — a mannequin that lists at $37,320 however usually sells for $34,590, in line with Edmunds. That suited me nicely because it solely lacked a couple of options of the high-end XSE Premium, notably the bigger 13.2-inch infotainment show and photo voltaic roof possibility. A totally outfitted 2026 XSE Premium mannequin with these options prices $41,665.

Since Toyota additionally makes a daily hybrid Prius, that car provides a really perfect comparability. The equal Prius XTE mannequin has an inventory value of $31,995 in an analogous configuration, making it $5,325 cheaper than the Prius Prime XSE.

The typical US driver covers 13,662 miles per year and gasoline at present has a median $3 per gallon value. Over that distance, a non-PHEV Prius driver may anticipate to burn 273 gallons at 50 MPG (EPA mixed) in a yr, spending $819 on gasoline.

A Prius Prime driver, then again, would use 70 to 85 p.c much less gasoline by present EPA or WLPT estimates. If we generously take the excessive finish of these numbers at 85 p.c, that cuts gasoline prices to $160. That will require utilizing about 2,500 kWh of electrical energy, although, so at a median US value of $0.18/kWh, that quantities to $450, for a complete of $610 (fuel plus electrical energy). Which means you’d save simply $209 in a yr, or $2,090.00 over 10 years — not sufficient to justify the additional value. (Gasoline and electrical energy costs, utilization and different components range by area and might have a huge impact on these figures.)

It might be even worse than that, in line with a European automotive thinktank known as Transport & Atmosphere (T&E). After gathering real-world OBFCM data from 800,000 autos, they decided that PHEVs solely run in all-electric mode 27 p.c of the time, relatively than 84 p.c as estimated by Europe’s WLPT normal. Consequently, plug-in hybrids in Europe emit 5 instances extra emissions and value customers €500 ($586) extra per yr than beforehand thought. These figures are possible related within the US.

How may regulators be so flawed about this key information? The primary, apparent purpose is that they underestimated how usually folks cost their autos. With their comparatively quick vary, plug-in hybrids usually want a full cost to get via the day in electric-only mode — however many individuals aren’t doing that.

Why? One purpose could also be an absence of simple charger entry away from dwelling. I discovered them to be tough to search out and use, usually requiring a sign-up or app relatively than simply letting me faucet a bank card (I’m taking a look at you, ChargePoint, Flo and Swap Power). It may also be dearer than simply shopping for gasoline, since many firms cost triple or extra the market price for electrical energy. One other issue is that drivers of firm or fleet PHEVs charge their vehicles less often than personal homeowners.

There’s one further and particularly pernicious purpose: The ICE engine usually kicks in when PHEVs are supposedly working in all-electric mode, significantly with heavier sedans or SUVs. That’s as a result of the electrical motors alone aren’t highly effective sufficient for maneuvers like passing.

Bigger batteries can increase all-electric utilization, however solely to a degree. Past 45 miles of vary, emissions really improve. The reason being easy: “Lengthy-range PHEVs are the heaviest within the dataset, averaging 28 p.c extra mass and 33 p.c extra engine energy than the group slightly below,” T&E wrote.

Total, I loved my time with the Prius Prime and located it to be enjoyable, sensible and low-cost to drive. It’s essentially the most economical PHEV as a result of it has glorious electrical vary and sufficient energy that the ICE engine hardly ever must kick in. On the identical time, it provides the best EPA mileage score of any non-EV bought in North America. If I have been out there for a brand new car, the Prius Prime could be excessive on my listing.

Nonetheless, I additionally realized that PHEVs aren’t decreasing emissions or saving consumers as a lot as regulators and producers have promised. Governments are guilty for a lot of that, as they overestimated all-electric use in PHEVs and didn’t help the charging infrastructure wanted to make them sensible.

Duty additionally falls to automakers and consumers. Shoppers need SUVs, however producers aren’t making the electrical motors in PHEVs highly effective sufficient to run on a regular basis in EV mode or providing quick DC charging. On the identical time, drivers are failing to cost their autos persistently. Till these points are solved, in my expertise plug-in hybrids are a poor substitute for EVs by way of emissions and a much less economical alternative than common hybrids.
