Porsche 911 vs Toyota Prius

What's the difference?

The more things change, the more they stay the same. The t-hybrid might be an entirely new propulsion system for the 911, but the net result is unchanged – power, poise and performance on tap.

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.

This facelift debuts a revolutionary exterior design that has completely reshaped the 911.

Just kidding. If it ain’t broke and all that. The front air vents and exhaust have changed, the former now an active intake system that deploys via vertical flaps, but elsewhere it’s largely evolution over revolution.

Instead, Porsche has focused most of the updates in then cabin. In here, you’ll find a new digital instrument panel, they’ve changed some of the levers and the steering wheel.

In true Porsche fashion, though, this new 911 mimics the older versions in that it's one of the more intuitive cabins you’ll ever sit in. Everything feels as though it’s exactly where it should be, and all feels entirely centred on the driver.

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.

This probably falls under the ‘next question, please’ umbrella, given that, while the Porsche 911 is known for a lot of things, vast acres of space with loads of practicality perks just ain’t a part of its portfolio.

The new 911 measures a not-insubstantial 4533mm in length, 1852mm width and around 1294mm in height, and it rides on a 2450mm wheelbase. Luggage space is a paltry 135 litres under the bonnet, plus whatever else you can fit in your pockets.

There’s seating for four, should you not like the people you’re squeezing back there very much, but really the 911 is best enjoyed as a two-seat proposition – which is why you can also delete the backseat, should you wish.

It also weighs a minimum 1595kg, or up to 1745kg, but Porsche says the hybrid tech only adds about 50kg to the total kerb weight.

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.

A new (or at least, massively altered) 3.6-litre petrol engine has been developed for this T-Hybrid, which combines with two electric motors to produce a total 398kW and 610Nm. It’s only available with Porsche’s very good eight-speed Porsche Doppelkupplung (PDK) automatic, largely because the brand admits it would be… well… unpleasant to drive as a manual.

Now, there is lots of magic at work here, and I don’t want to bore you, but the Porsche setup sees a lightweight 1.9kWh battery placed basically in the middle of the front axle, and a 12-volt battery now behind the front seat. Then, a tiny e-motor lives as part of the gearbox (it’s just 55mm long) and delivers up to 150Nm at low speeds to supplement the petrol engine.

It’s joined by what Porsche calls an “electric exhaust gas turbocharger”, which essentially removes the spooling time from the turbo, delivering instant power.

The aim of the game here is excitement, not efficiency, and the launch-control-aided spring to 100km/h takes just 3.0 seconds. And it somehow feels, and sounds, faster.

The latter being important, with Porsche aware that if the new powertrain didn’t sound good, "nobody would like it”.

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.

Porsche in Australia is yet to lock in local fuel use for the Carrera GTS T-Hybrid, but international testing has it at 10.5-10.7L/100km, C02 emissions of between 239-244g/km. 

Those aren’t exactly Toyota Prius numbers. But again, that was never Porsche’s intention. The electric power on offer here is intended to improve acceleration, not fuel use.

It’s fitted with a 63-litre fuel tank, which should deliver a driving range of around 600km per tank.

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.

Porsche did just about the Porschiest thing to ever Porsche in launching the 911 Carrera GTS T-Hybrid, in that we piled into cars in Melbourne, drove the many, many hours (well, it feels that long, at least) to the Phillip Island race circuit, beat the hell out of the cars on track and on the drag strip for several hours, then trundled back out on the road and drove them back to Melbourne.

The subliminal messaging here is pretty clear. This new 911 might have a new powertrain, but it can still deliver the road-track-road experience without breaking a sweat — or, more importantly, without breaking any expensive bits.

So let’s do this in order, shall we? On the road, this new 911 is every bit as sweet as it has ever been. Comfortable, quiet enough when you want it to be, and — save some road noise from those big wheels – quiet enough to let you forget you're driving something with one of Peter Dutton’s nuclear reactors hidden beneath its svelte metal work.

Mind you, that T-Hybrid powertrain will happily remind you of its presence every time you press the accelerator in anger, the exhaust erupting into life and the 911 genuinely rocketing into the future, but stay gentle with your inputs and this hybrid 911 is a genuinely comfortable, genuinely liveable daily driver.

Its split personality appears when you rumble out onto a race track though, where you quickly discover the electrified, and electrifying, Porsche is properly, properly rapid, both in a straight line or around Phillip Island’s fast and flowing circuit.

It’s so rapid, in fact, that it feels most closely related to a performance EV, like the Taycan. Of course it is louder and more engaging, but that’s the best way I can think of to describe the instant power on offer here. There’s no ICE-like lags or lumps in the way that 398kW and 610Nm finds its way to the tyres and into the tarmac. Instead it’s just this constant, savage flow of power that never seems to let up.

Porsche says this new powertrain is about 50kg heavier, but you’d need to be plugged into the race track like its the Matrix to ever feel it, with the T-Hybrid feeling lithe, grippy and athletic, aided by near-perfect steering, the best automatic gearbox in existence, and exactly zero roll through the body. In fact, the only thing that really moves when cornering hard in this new 911 is the driver, and I genuinely got out after several laps with a sore neck from trying to stay vertical.

Downsides? Well, it’s faster in a straight line (it will be some 7.0m further down the road after 2.5sec when compared to the older GTS) and faster around corners (8.7sec faster around the Nurburgring than its predecessor), but there’s something delightfully analogue about the outgoing car, which also manages to feel more aggressive under heavy acceleration, too, owing to the little ebbs and flows of power, and after driving both back-to-back, I still can’t decide which one I like more.

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.

The 911 Carrera GTS is covered by a pretty underwhelming three-year, unlimited-kilometre warranty, with servicing required every 12 months or 15,000kms. We don’t have the hybrid service pricing yet, but as guide, the last 911 split the services into minor and major, and charged either $785 or $1285 for each.

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.
