Porsche Taycan vs Toyota Prius

What's the difference?

Porsche says its Taycan models have always been performance-focused and this updated version is even faster than the car it replaces, in a straight line and point-to-point. It’s better equipped, more efficient, and yes, more expensive but every millimetre a Porsche in the way this EV sedan and wagon package has been executed.

It’s an impressive car likely to appeal to Porsche newcomers rather than traditionalists, although you may already have other Porsches in the garage. But with the Macan EV landing any minute and the pure-electric 718 Boxster and Cayman just around the corner it's a key part of the changing face of this iconic German brand.

The Prius can rest its weary head. The Age of the Hybrid has begun. Even though this iconic eco car might have lost its ultimate purpose to more mainstream models in the last few years, it’s still the best execution of Toyota’s hybrid tech on the market and if you can look past its divisive-as-ever looks, it’s comfortable and practical, too.

The brand’s Australian division promises the Prius will stick around in one form or another, so we’re keen to see what its next iteration will look like. Plug-in? Fully electric? Time will tell.

Porsche has freshened up the Taycan’s front and rear end, the nose losing the vents dropping down from the headlights as previewed by the original Mission E Concept in 2015.

Matrix LED headlights are standard with high-resolution HD available. But there are no major sheet metal changes to the bulk of the car. And why would you fiddle with it? The drag coefficient is an ultra-slippery 0.22.

Around the back the Porsche logo in the rear light strip has been given a cool three-dimensional treatment al la the 911, Panamera and other current Porsches. And if you have eyes for the Turbo or Turbo S the brand’s glamorous ‘Turbonite’ metallic silver colour is now available.

Inside is a screen-rich environment with a three-dial digital version of the brand’s five-dial instrument cluster customisable through roughly 5000 configurations and there’s a new multimedia software interface for the central screens with additional functions. A passenger display is a $2860 option.

The Prius is the very visage of economic motoring. Derided by big-engine lovers, and adored by the eco-crowd, the fact that the Prius’s wedge-shaped frame is more about function than form tells you everything you need to know about this car.

It blends with Toyota’s latest design language, the face and bodywork containing some subtle nods to other models that would launch after it, like the Corolla, Camry, and C-HR.

What always surprises me about even this top-spec Prius is its dorky ride height. For a car with such a low drag coefficient, it sits so far off the ground! The 17-inch wheels look almost out of alignment with the body in those wheelarches.

Round the back, the Prius’s integrated spoiler and glasshouse bodywork are as divisive as ever, with more extreme pointed light fittings leaning into the effect created by its boxy, rear three-quarter view and mirroring the shape of the LED headlights at the front.

Of course, this car is less about being looked at as it is about its drag coefficient of 0.24 Cd, which is one of the lowest on any production car.

Inside, things again prove divisive, with a minimalist dash, a swoopy gloss highlight piece that frames the central vents and multimedia screen, and an odd, centrally mounted dash cluster, which is a usability faux pas.

In the case of the I-Tech at least there’s a holographic display which can put up useful information to help prevent your eyes from drifting too far from the road. Still, I can’t help but feel like this whole interior ethos is futuristic for the sake of being futuristic, with a little less thought given to how practical it is, compared to the brand’s other models.

The leather-appointed trim across the wheel and soft plastics in the door and dash-topper are appreciated, and there’s attention to detail in the little ‘Prius’ logos on the vents. However, I found the dull multimedia screen to be susceptible to glare during the day, and the big integrated panel in which it sits is made from a tinny gloss plastic, which will easily to get covered in fingerprints and scratches.

At nearly 5.0m long and 2.0m wide but less than 1.4m tall the Taycan is a low-slung large sedan.

In the front of the Taycan I’ve got plenty of breathing space, lots of headroom and enough shoulder room and you don’t feel cramped relative to the co-pilot.

In terms of storage, there are pockets in the doors with room for bottles, a couple of cup and bottle holders in the centre console as well as a tray under the flying buttress type upper console section.

A lidded box between the seats housing a couple of USB-C outlets and a 12-volt socket is handy and there’s a decent-size glove box on the passenger side. 

Interestingly, an in-car video function enables video streaming on the central display (while the vehicle is stationary) and the passenger display at any time with the vision hidden from the driver by a lenticular-style screen.

In the back, sitting behind the driver’s seat, set for my 183cm position, I have ample legroom and space for my feet. Problem is my head hits the roof solidly, even with the extra room afforded by the panoramic glass insert, which is a no-cost option from the Taycan 4S up.

Standard configuration is two rear seat positions, although a ‘4+1’ set up which adds an occasional centre rear position is optionally available. Trust me, that’s tight. 

On the upside you have adjustable ventilation for the rear seat passengers (climate control zones on the Turbo grades) with a small oddments shelf below them, slots in the doors for bottles and two more cup or bottle holders in the fold-down centre armrest.

No map pockets on the front seat backs, so while there’s some room for storage it’s not exactly over supplied in that department, or for breathing space in general.

Boot space is relatively modest at 366 litres in the sedan but the 60/40 split-folding rear seat liberates more space if required. The Cross Turismo wagon offers 405 litres and a much larger load aperture for greater flexibility. An 84L frunk sits in the nose of all Taycans.  

Interesting to note Taycans in other markets boast an extra 41L of boot space. It doesn’t feature here because Porsche Australia has made the high-end Bose sound system standard and its sub-woofer eats into available capacity. 

A power boot lid or tailgate and auto self-levelling to maintain the car’s ride height under load is standard but there’s no spare tyre of any description. A repair/inflator kit is your only option, which is less than ideal.

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.

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.

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.

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.

The entry-level single-motor RWD Taycan features a new electric motor that’s 10kg lighter and seven per cent more powerful but more notably produces 22 per cent more torque than the unit it replaces.

Both it and the additional motor fitted to the front axle of AWD models are permanent magnet synchronous units with outputs up across the range, the Turbo S producing a stonking 700kW and more than 1100Nm.

That 700kW peak number for the Turbo S comes courtesy of an ‘overboost’ function with Launch Control. And Taycan models equipped with the Sport Chrono package and the Performance Battery Plus have up to an extra 70kW courtesy of a 10sec push-to-pass button.

There’s a two-speed transmission on the rear axle and a single-speed on the front of AWD variants.

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 Taycan runs 800-volt electric architecture which means it can charge at up to 320kW on a DC fast-charger which is 50kW more than its predecessor. In fact, charging at more than 300kW for up to five minutes is possible. 

You’re looking at a 10-80 per cent charge in 18min on a fast charger which is down from 37min. It’s 46min on a more typical 120kW charger.

An 89kWh lithium-ion battery is standard on the entry-grade Taycan. It boasts a nickel, cobalt, manganese cell chemistry which Porsche says delivers high energy content, lower internal resistance and higher charge and discharge currents. And it’s 9.0kg lighter.

All models above it feature the 105kWh ‘Performance Battery Plus’, a roughly $12K option on the base car.

Maximum AC charging capacity is 11kW and you’re staring down the barrel of nine hours for a 0-100 per cent fill of the smaller battery and 11 hours for the performance battery pack.

Official energy consumption on a combined urban, extra-urban cycle varies from 17.1kWh/100km for the single motor Taycan to 17.8kWh for dual-motor variants.

On the launch drive program, covering mainly rural B-roads on Tasmania’s east coast, we cycled through all models on offer and recorded a best figure of 21.5kWh/100km for the single-motor Taycan up to 22.0kWh for the Turbo S. Not bad.

Claimed range is 566km for the entry-grade Taycan, up to 626km for dual-motor models.

Interestingly, on 4WD models the - front electric motor can electronically decouple more frequently to improve efficiency.

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.

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.

Full disclosure. My preference when it comes to Porsche propulsion is pistons in cylinders; ideally six of them, horizontally opposed. 

But if the Taycan is on your shortlist you’re ready to move past internal combustion and there is no doubt this car is properly quick. 

The entry-level RWD model accelerates from 0-100km/h in 4.8sec (0.6 faster than the outgoing model) with the Taycan Turbo S at 2.4sec which is hypercar fast.

Porsche admits to having played around with some dual-clutch transmission-type mimicry along the lines of the Hyundai Ioniq 5 N. But the boffins in Zuffenhausen left that to one side due to concerns over compromise to the car’s point-to-point ability. Porsche seemingly can’t entertain anything that makes a car slower.

It did, however, install a push-to-pass function on dual-motor versions which gives you a 10-second burst of extra performance which is fun.

Suspension is by forged alloy double-wishbone front and rear with some extra links at the back.

Adaptive air suspension is standard across the range, and ‘Active Ride’ is fitted to the upper variants which takes things one step further.

And it does ride very nicely. The launch drive covered second-class, coarse-chip B-road type surfaces and the Taycan smooths the road out beautifully.

Standard wheel diameter is 19-inch for the entry-grade, 20s for the 4S and Turbo, then 21s on the Turbo S. The cars on the launch program all featured 21-inch rims shod with Goodyear Eagle F1 or Michelin Pilot Sport 4 rubber and even on those big wheels the car still rides well.

In terms of the steering… hey, it’s a Porsche. It’s fantastic. Accurate and direct without being too jerky or snappy. It does exactly what you want the car to do. The connection with the front tyres feels like it’s almost direct.

This car may be lighter than its predecessor but all models are over 2.0 tonnes so you’d expect it to be heavy and slow. It’s not. Point and accelerate through corners with supreme confidence. It’s beautifully balanced. What you’d expect from a Porsche performance car.

Physical braking is by big ventilated discs all around with six-piston aluminium monobloc fixed-calipers at the front and four-piston units at the rear. Suffice it to say they wash off speed effectively. 

Believe it or not the Turbo S’s front brake calipers contain no less than 10 pistons, clamping ceramic composite rotors. We gave all Taycan variants a solid workout on the Baskerville Raceway just north of Hobart and stopping power felt as strong and effective at the end of the session as it did at the start.

There’s also improved recuperation capacity for the regenerative braking system, up 30 per cent from 290 to 400kW.

In terms of miscellaneous observations, beware the 11.7m turning circle. What might appear to be a three-point turn situation often turns into a five-pointer.

And entry to cars fitted with Active Ride is made easier (when activated). As soon as a door is opened, the body raises by 55mm. May seem OTT but it makes life with the Taycan that bit better.

The Prius was responsible for popularising Toyota’s Hybrid Synergy Drive, and fittingly, it still feels like the best execution of the technology on the market. That instantly available torque from the electric motor is sleek, quiet, and easy. It feels as though the Prius can make more extended use of purely electric drive than not only its rivals, but all other Toyota and Lexus hybrid products.

Despite its awkward exterior looks, the ride and handling of the Prius are excellent, thanks to its robust TNGA-C underpinnings (in fact, the Prius was the car to debut this platform for Toyota). It tilts into corners nicely, despite a frumpy ride height, and deals with bumps in its stride. This is a comfortable car, and the Lexus influence here is undeniable. The steering characteristics are also smooth and responsive. I wouldn’t go so far as to say the Prius is fun to drive, but it is certainly comfortable and compliant.

What the Prius lacks is the lower, firmer, and more aggressive ride and handling characteristics of its Hyundai Ioniq rival, perhaps a telling insight into the trajectory of each brand.

These characteristics add up to an around-town driving experience that really is a breeze. It’s quiet in the cabin and at times genuinely hard to tell whether the car is using its electric motors or the engine. When it comes to bursts of acceleration, the Prius might surprise you. Using both the motor and engine in tandem, I found that the Prius can sprint from the line with an alarming urgency, more so than its Corolla sibling. With the same tech behind the accelerator pedal, it’s hard to imagine why.

Once the electric motor has reached its strictly defined limit, though, the engine breaks in with a vengeance, and this car does have an anaemic follow-through when the electric components fall to the wayside. As in other applications of this drivetrain, the 1.8-litre Atkinson-cycle petrol engine can be thrashy and noisy when a lot is asked of it.

Of course, driving in such a sporty manner is hardly the point of the Prius, and where it really excels is in that day-to-day traffic grind, where the hybrid system works largely in the background to maximise the time spent with the engine off. The best part? While you can really fall into the hybrid system’s addictive fuel-saving displays, which really encourage hypermiling, this is a set-and-forget system. You can drive the Prius like any other car, and it will be trim on fuel consumption anyway. It’s not like I was trying awfully hard to attain my weekly figure of 4.0L/100km, so I’m sure it can do better over the long term.

The Prius wears a maximum five-star ANCAP safety rating to the 2016 standards, although even in today’s market it has a great active-safety suite.

Standard modern active features on all Prius models include freeway-speed auto emergency braking with pedestrian and daytime cyclist detection, lane-keep assist with lane-departure warning, adaptive cruise control, traffic-sign recognition, and auto-high beams. Our top-spec I-Tech adds blind-spot monitoring and rear cross traffic alert, for an overall excellent suite.

All Prius varaints are also equipped with seven airbags consisting of the standard front, side, and head, as well as a driver’s knee airbag, and the standard array of electronic stability and brake controls are also present.

Porsche covers the Taycan with a three-year, unlimited km warranty which is off the pace for the premium segment where five years, unlimited km is the norm. The high-voltage drive battery is covered by an eight-year, 160,000km warranty. The paint is covered for three years and a 12-year (unlimited km) anti-corrosion warranty is included.

Porsche Roadside Assist provides 24/7/365 coverage for the life of the warranty, and after the warranty runs out is renewed for 12 months every time the vehicle is serviced at an authorised Porsche dealer.

Thanks to fewer moving parts, servicing intervals for the Taycan are relatively lengthy at two years or 30,000km, whichever comes first. 

With Porsche, final costs are determined at the dealer level (in line with variable service labour rates by state/territory).

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.
