Toyota Prius vs Alfa Romeo Giulietta

What's the difference?

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.

So much right and some things not quite right – the Giulietta has the Alfa Romeo mix of highs and lows which the brand is famous for. There’s no mistaking that this is a unique and sexy looking car, with the practicality of a five-door hatch plus impressive handling and performance.  More heart than head decision here though it seems, but romantic Alfa enthusiasts should adore it.

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.

Alfa Romeo couldn't design a boring car even if it was handed a picture of a Toyota Camry and told to copy it or else. The Giulietta is no exception.

There's the deep 'V' grille shared with the new Giulia sedan and 4C sports cars that make up the current Alfa model line-up. There's the bug-eye headlights with pretty inset LEDs and the chiselled bonnet, a side profile which looks like that of a mini Porsche Cayenne and a cute-but-tough bottom with its elegant taillights and twin exhausts.

The latest update brought a honeycomb mesh grille and a slightly different design to the headlight and LED foglight surrounds. The tail pipes were also given a styling tweak, so too were the alloy wheels.

Despite its coupe looks it's actually a five-door hatch with ‘hidden' handles for the rear doors.

The cabin saw new materials and finishes added. The Veloce had the Alfa Romeo logo stitched into the integrated headrests, shiny sports pedals, and lashings of faux carbon fibre trim on the doors and dash.

You can tell a Veloce from the outside by the red Brembo brake calipers behind the front wheels, 18-inch alloys, its chunkier exhaust tips poking out of the diffuser, red pin-striping to the front and rear bumpers, and the black window surrounds.

Okay, how big or small is it? Here's some dimensions for you. The Guilietta is 4351mm long, 1798mm wide, 1465mm tall and the Veloce with its sports suspension is 9mm lower than the others with 102mm of ground clearance.

Compared to say a Mazda3 hatch the Giulietta is 109mm shorter end-to-end and only 3mm wider. But if you're considering an Giulietta why are you looking at the Mazda3 anyway? That would be sensible - Like comparing Cancer Council hats to top hats.

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.

Beautiful things tend to favour form over function. The Giuletta tries to do both and succeeds…but also fails in places.

Successes first: despite its coupe looks it's actually a five-door hatch with ‘hidden' handles for the rear doors placed up at window level near the C-pillar. So good is the two-door disguise that our photographer climbed into the back seat through the front door.

Rear legroom is a bit tight back there and at 191cm I can sit behind my driving position but I'd hate for me to be sitting behind me because my knees are digging hard into the seat back.

Headroom isn't much chop either and I literally can't sit in the back seat and hold my head high – a combination of that sloping roofline and the optional double sunroof reduces the head space.

A major practicality fail is the lack of storage throughout the cabin.

Ordering drive-thru is possibly out of the question.

My wife's phone kept mysteriously appearing in the footwell every time we left it in the glove box, like there was a tear in the time-space fabric, but then we realised it was slipping through a gap.

There's no centre armrest storage bin in the front – actually there's no centre armrest. There is a pop-up hidey-hole on the dash but with only enough room for a pair of sunglasses.

The two cup holders in the front are small. It's safe to say that unless you have somebody with hands at the ready, ordering drive-thru is possibly out of the question.

Or if you have long arms and can reach the fold down armrest in the back there are two decent sized cup holders along with a small storage space. There are no bottle holders any of the doors, but there is fortunately room for a phone and wallet because there isn't space for them anywhere else.

But wait, the Giulietta is saved from a total storage fail by a large-for-the-class 350-litre boot. That's 70 litres bigger than a Toyota Corolla's and only 14 litres less than the Mazda3.  We could fit the pram, the shopping and the rest of the gear which goes with a military operation such as a trip to the park with a toddler in there.

The 2016 update saw the Giulietta variants renamed. There's the entry grade $29,990 Super Manual which has a six-speed manual gearbox, then buyers can step up to the Super TCT with a six-speed dual clutch automatic transmission for $34,900 and then there's our test car – the Veloce for $41,990. There's 10 paint colours at your disposal from the colour of our car (Alfa Red) to Perla Moonlight. Only Alfa White comes at no extra cost, the rest are a $500 option.

The Veloce collects the same features as the Super TCT such as a 6.5-inch touch screen, with sat nav, front and rear parking sensors, three drive modes and then adds bi-xenon headlights, 18-inch alloys, leather and Alcantara seats, a flat-bottomed steering wheel, the big exhaust tips and the sports diffuser, tinted rear glass and then less cosmetic features such as sports suspension and launch control.

There's no reversing camera which is disappointing, considering they come standard on some cars half the price.

At this price you'd shop the Veloce against a BMW 120i hatch for $41,900, a Volkswagen Golf GTI for $43,490 or possibly a high-end Mazda3 SP 25 Astina for $37,040.

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 Giulietta Veloce has a 1.75-litre four-cylinder turbo-petrol engine which produce 177kW of power and 340Nm of torque. It's a great engine that lets loose a wonderful scream when pushed hard and the little grunts it makes when it changes gear when driving around normally sound like a giant enjoying his food.

The transmission is a dual-clutch auto which Alfa calls a TCT or twin-clutch transmission. I'm not a fan of them regardless of the brand of car they're in but the Alfa version is better than most of the others in its smoothness at lower speeds and decisiveness.

There's so much potential here for a great driving experience.

What about the Giulietta's reliability over time? This version of the car is less than two months old so we can only comment on what it offers as a brand-new vehicle, but you'll find good context in our used review of the earlier 2011-2014 Giulietta.

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.

Alfa Romeo says you should see your Veloce drink at a rate of 6.8L/100km during combined driving, but the dash showed more than double that during mainly urban driving while  channelling  Enzo Ferrari.

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.

There's so much potential here for a great driving experience such as the accurate and direct steering and great suspension which provides a comfortable ride and great handling, only for all to be let down by turbo lag which kills the responsiveness in the car.

Of the three steering modes: Dynamic, Natural and All Weather, the Dynamic setting was kept on almost always with the other two just feeling too lethargic.

The Giulietta is front-wheel drive and there's a lot of torque being sent to those wheels, but unlike a stack of Alfas in the past there's next to no torque steer. That said, our hill start test on a wet night saw those front wheels scrambling for traction as it accelerated up the slope. Cornering grip from the tyres is excellent, however.

There's some Alfa Romeo ergonomic issues in the cabin we've gotten used to over the years, but just because you're accustomed to something doesn't mean it's okay. For example, the cramped driver's footwell with the brake and accelerator pedals so close that it's easy to hit both at the same time.

Such is the intensity of the spray from both the window washer and the headlight washers it's like you're captaining a fishing trawler that's hit a massive wave at sea.

The indicator and wiper stalks are also so far from the steering wheel rim that they're almost out of reach – I don't think I have small hands, nobody's ever pointed them out or laughed at them.

And speaking of wipers, the Giulietta is obsessed with keeping itself clean. Pull the wiper stalk towards you to clean the windows and such is the intensity of the spray from both the window washer and the headlight washers it's like you're captaining a fishing trawler that's hit a massive wave at sea. Put the car into reverse and the rear wiper starts squirting and washing.

For Christmas I want Alfa to upgrade their media unit or bin it – the UConnect system disconnected my phone without prompting and isn't intuitive to use.

The Alfa Romeo Giulietta has been given the maximum five-star ANCAP rating. It doesn't have the advanced safety technology such as AEB and lane keeping assistance which is now standard on any small hatches for a lot less money.

For child and baby seats there's two top tether and two ISIOFIX points in the back seat.

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.

The Giulietta is covered by Alfa Romeo's three year/150,000km warranty. Servicing is recommended at 12month/15,000km intervals with a major service every two years. Alfa Romeo doesn't have capped price servicing but there is Mopar Vehicle Protection which customers can purchase with the vehicle for $1995.
