Toyota Prius Hybrid 2021 review: i-Tech

This Toyota Prius in top-spec I-Tech form costs a whopping $45,825 before on-road costs, which is a tall order, especially given the fact that the technical advantage this car once had to help justify its price-tag has been lost to the rest of Toyota’s range.

An equivalent Corolla hybrid, even in top ZR trim, can be had from just $34,695, and even the much larger Camry in its highest hybrid SL trim is more affordable, at a suddenly cheap-looking $42,790. All three Toyotas are sourced from Japan.

Not a good start in the value battle, then, especially since those other Toyotas are not just hybrids, but great cars in their respective segments.

The Prius I-Tech’s most direct rival is the similarly shaped and sized Hyundai Ioniq Premium, which can be yours from $40,390 with competitive equipment. Hyundai is not only hunting Toyota with this car, but flexing its deep pockets by selling the Ioniq in Australia as not just a hybrid, but a PHEV and a full EV, too.

Thankfully, the I-Tech comes with some decent gear, sporting 17-inch alloy wheels, a 7.0-inch multimedia touchscreen with Apple CarPlay and Android Auto connectivity, digital radio, a 4.2-inch digital information display, a holographic head-up display, full LED lighting with auto-levelling, leather-appointed seat trim, auto dimming rear vision mirror, wireless phone charging, 10-speaker audio, and improved interior trims over the base car.

The I-Tech also scores a larger boot capacity and an improved safety suite compared to the base Prius. More on that in later sections of this review.

Is the Prius “good value” then? It's still a no, as all of this equipment can be had in bigger, more mainstream Toyota models, and far more affordable rivals. It’s a shame Toyota hasn’t brought the Prius’s cost down in the five years since this generation launched, because in today’s market it makes less sense than ever.

That said, there is a certain niche audience for this car. One that will always love its little innovations, like the fact that it has one of the lowest drag coefficients on the market, its stellar fuel-consumption number, and its claimed 40 per cent thermal efficiency.

If nothing else, all of the Prius’s edgy design gives it plentiful interior space. Toyota granted this generation of Prius a low seating position and tall roof, which combine with the distant dash elements to make for a spacious cockpit for the front two occupants.

The seat design in the top-spec I-Tech is also cushy, reminiscent of the seats in high-spec Camrys, and I had absolutely no trouble finding a comfortable driving position. If there’s one thing to be said for the annoying, centrally mounted instruments, it’s that you don’t need to consider the position of the wheel interfering with their visibility.

The Prius’s total glasshouse grants superb visibility out the front and sides, with large wing-mirrors, too. The only downside is that integrated spoiler at the back, which makes for a distracting view out the rear mirror that I’m sure any owner will quickly become accustomed to.

If nothing else, all of the Prius’s edgy design gives it plentiful interior space.

Soft trims across the doors and centre console, even in the back seat, make the Prius cabin a comfortable place to be, too.

Ergonomics have not been forgotten, with the multimedia screen and climate unit having useful and easy-to-reach physical dials and toggles for all the key functions. Even changing gear is a breeze in the Prius, with its odd little rosebud-shaped shifter simply a flick of the wrist from where your arm sits.

I do wish Toyota had made better use of the large area under the climate unit, however. The front part of the centre console is exclusively for the wireless-charging bay alone, and the rest of the space is constructed from a smoothly contoured gloss-finish plastic panel. It has looks to match the Prius aesthetic, but it’s no good for storing anything other than a single phone. It would have been better to make a large bay here with a rubberised finish.

Thanks to the lack of a physical handbrake in the centre or any other buttons or functions, there are two large bottle holders with variable edges.

Room in the rear seat is excellent, and the comfy seat trim continues.

A huge centre-console box and large door bins round out the Prius’s front-seat storage options.

Room in the rear seat is excellent, my 182cm tall frame had stellar amounts of space for my legs and head, as the roofline continues through to that raised rear spoiler. The comfy seat trim continues, although the padding in the base is notably not as good as it is in the front.

There are some useful pockets on the backs of the front seats and a drop-down armrest with cupholders for rear passengers, too.

Finally, the awkward rear of the Prius makes for a fantastic boot capacity, one advantage this car still holds over its hybrid Toyota stablemates. Capacity for the I-Tech is a mid-size-SUV rivalling 502-litres (VDA), which easily consumed our CarsGuide test luggage set and is even bigger than the base Prius, at the cost of the space-saver spare wheel. The I-Tech only has a repair kit to go with its larger alloys.

It wouldn’t be a Prius without Toyota’s signature hybrid synergy drive technology. In this most original case it consists of a 1.8-litre four-cylinder petrol engine, which uses the more thermally efficient but less powerful Atkinson combustion cycle, producing 72kW/142Nm, paired to a set of electric motors on the front axle, which can produce up to 53kW/163Nm.

Combined system output is rated by Toyota at 90kW, driving the front wheels only via a continuously variable automatic transmission (CVT). This system is the same one now also employed in the C-HR and Corolla hybrid grades.

The Prius’s electric motors source their power from an older design nickel-metal hydride battery (instead of the more modern lithium-ion setup) located under the boot floor.

The Prius’ sandpapered hybrid drive, low drag number, weight reductions, and low-rolling-resistance tyres add up for a stellar official/combined fuel-consumption figure of just 3.4L/100km. While its signature hybrid tech might be available on other Toyota’s, it’s here where the Prius still shines, undercutting the others by almost a whole litre every 100km.

But can it live up to that promise in the real world? Over my week of what I would consider to be reasonable ‘combined’ driving conditions; with plenty of traffic, freeways, and suburban driving, the Prius returned a stellar figure of just 4.0L/100km. This is not just one of the lowest figures I have ever achieved on a test car, it is even lower than the Corolla Hybrid that I tested over a three-month period. I couldn’t get that car below 4.9L/100km, despite by best attempts.

It’s clear that the Prius is still the king of hybrid, then. At least for the time being.

For a true rival comparison, my week-long test of the Ioniq hybrid in 2019 had the Korean managing a fuel number of 4.6L/100km.

You need not worry about kWh energy consumption for the Prius, as its hybrid system’s software manages the state of battery charge on the fly. It will simply run the engine to charge the battery if levels drop too low, although it always feels good to make the most of the motor’s regenerative braking to keep the battery topped up.

It’s clear that the Prius is still the king of hybrid, then. At least for the time being. All Prius models have 43-litre fuel capacities and are able to consume base-grade 91RON unleaded.

Toyota’s range-wide warranty currently stands at five years or unlimited kilometres, which is really the accepted industry standard and matches its key Ioniq rival.

Annoyingly, however, the Prius needs to adhere to six-monthly or 10,000km service intervals. Said intervals are capped to $165 per visit for the first six visits under Toyota’s “service advantage” program, after which time you fall back to Toyota genuine servicing with significant price hikes to $221.97, and $425.47 for the next two services covering four years or 80,000km.

A year of roadside assist is included, after which time you will need to subscribe to Toyota’s program, from $89 a year.

While Toyota’s offering is on par with many, it’s hardly the cheapest or most comprehensive we’ve seen.
