Infiniti QX30 vs Hyundai Tucson

What's the difference?

Even though it’s almost identical to the Q30, the QX30 manages to feel sufficiently different in suspension tune and cabin ambiance to be considered different.

It’s a disappointing oversight, though, by Infiniti to deny the base GT such basic safety fundamentals as a rear view camera (which Infiniti assures us is being worked on).

As Toyota has found with the RAV4, these types of ‘self-charging hybrids’ are popular with customers because they offer more performance, lower fuel economy and require no change in behaviour - no plugging in or managing battery range.

There’s a very good reason for Hyundai to add the Tucson Hybrid to the local line-up, because it will expand the appeal of what is already a popular SUV. Many buyers have turned off diesel in the wake of the Volkswagen emission scandal, so hybrids such as these have greater appeal.

Especially if Hyundai can keep the price difference between the hybrid and diesel to a similar level to what we’ve already seen with the Santa Fe. In these current times of high petrol prices and cost-of-living pressures, anything that can make driving better financially we welcome.

The QX30 is one of the first projects to result from a technology partnership formed between the parent company of Mercedes-Benz and the Nissan-Renault Alliance.

In a sign of how worldly the car industry is becoming, the QX30 is built in Nissan’s Sunderland plant in the UK, using the German Mercedes-Benz A-Class platform and powertrains, all under Sino-French ownership via the Nissan-Renault Alliance.

On the outside, the design that first aired on the Q30 is pretty unique. It’s not a subtle car, with deep crease lines along its sides that, according to Infiniti, is an industry first in terms of manufacturing complexity.

When it comes to differences between the two vehicles, it’s minimal at best. There is a 35mm increase in height (30mm from taller springs and 5mm from roof rails), an extra 10mm in width, and extra trims affixed to the front and rear bumpers. Aside from the all-wheel-drive underpinnings, that is pretty much it for the exterior.

The same black plastic overfenders that are fitted to the Q30 are present on the QX30, with 18-inch rims on both the base model GT and the other variant, the Premium.

The dimensions of the QX30 are also an exact match for those on the Mercedes-Benz GLA, with the long front overhang acting as the main visual connection between the two cars.

What’s interesting about the design is that there isn’t anything unique about it, at least not overtly different from the rest of the Tucson range. As electrification becomes the norm rather than the exception, car makers have realised car buyers don’t need or want their electrified cars to be styled dramatically differently. 

As Toyota's decision to drop the Prius in Australia and instead relying on the Corolla to cater to buyers looking for a hybrid model demonstrates, buyers have evolved with their tastes. 

Instead both outside and in, the Tucson Hybrid is a regular-looking SUV that will appeal to anyone looking for a fuel-efficient model. 

The QX30 is obviously very similar to the Q30 in many respects, but the interior is slightly different, with larger, less cosseting seats up front and slightly higher seats in the rear.

The cabin is also lighter in overall appearance, thanks to a paler colour palette.

There are plenty of neat inclusions, including a pair of USB ports, plenty of door storage, a space for six bottles and a sizable glove box.

A pair of cupholders resides up front, along with a pair in the fold-down armrest in the rear.

There is no particularly logical location for the storage of smartphones, though, and the lack of Apple CarPlay or Android Auto is down to Infiniti opting for its own phone connectivity suite.

A decent 430 litres of luggage space behind the rear seats is contrasted by a cramped rear area for all but the smallest of passengers, while sharply shaped rear door apertures making getting in and out a bit of an ask.

There are two ISOFIX baby seat points and a 12-volt socket in the rear, as well.

Despite the addition of the hybrid powertrain elements the Tucson remains a practical family car. While it’s not the biggest SUV in its segment it offers adequate room for a family of four or five.

The front seats are comfortable and there’s good small item storage, as you’ll find in the existing Tucson range, with cup holders, a wireless smartphone charging pad, lidded console box and deep door pockets. The rear bench is good too, with enough room for my 180cm frame to fit in relative comfort, as well as cup holders in the fold-down armrest and a bottle holder in the door.

Crucially, the boot capacity is the same in both the petrol and hybrid Tucson in US specification, which means it should translate to the same 539-litres offered here. The boot floor is flat, which will make loading and unloading easier, but it’s worth noting that the US-spec model we drove had no space for a spare tyre and instead relied on a puncture repair kit.

While Hyundai may have confirmed the impending arrival of the Tucson Hybrid, the details are still under wraps. That’s likely because the hybrid will coincide with an as yet unseen mid-life refresh of the Tucson that was first revealed back in 2020.

Because of that there’s no public confirmation of pricing and specification for this new addition, but we can extrapolate what to expect based on the rest of the Hyundai line-up. Based on the recently added Kona and Santa Fe Hybrids, it’s a safe bet there’s likely to be two variants of the Tucson Hybrid. Expect an entry-level model - likely just called Tucson Hybrid - and a more luxurious variant - probably carrying the Tucson Hybrid Premium name, or possibly the Highlander badge.

Precisely what specification they will include and how much they will cost remains to be seen, but again we can probably take an educated guess based on what we’ve seen with the Kona and Santa Fe. The Kona Hybrid carries a $4000 price premium over its petrol-powered equivalent, while the Santa Fe Hybrid costs $3000 more.

So if the 2024 Tucson prices stay flat (which is possible but not guaranteed) expect the Tucson Hybrid to start around $46,900 and the Tucson Hybrid Premium/Highlander at $53,900.

Just the one engine is used across both cars; the 155kW/350Nm single-turbo 2.0-litre four-cylinder petrol engine from the Q30 and A-Class.

It’s backed by a seven-speed transmission and wired into an all-wheel-drive system that is biased towards a front-drive configuration.

Sourced from Mercedes-Benz, up to 50 per cent of drive can be sent to the rear wheels, according to Infiniti.

This is the heart of the matter, with the Tucson Hybrid combining a 1.6-litre turbocharged four-cylinder petrol engine with a small electric motor. The petrol engine makes the same power as the ‘SmartStream G1.6’ in the current Tucson, 132kW/265Nm. But the addition of the 44kW electric motor takes the total powertrain output to 168kW/349Nm.

The powertrain is paired to a six-speed automatic transmission as standard as well as Hyundai’s HTRAC all-wheel drive system.

Infiniti claims a combined fuel economy figure of 8.9L/100km for the 1576kg QX30 across both the variants; this is 0.5L thirstier than the Q30 version.

Our brief test yielded a dash figure of 11.2L/100km over 150km.

Hyundai USA rates the Tucson Hybrid fuel economy at between 6.1L/100km and 6.3L/100km depending on the variant. It must be noted that US fuel economy figures do alter to Australian numbers, but as a guide those figures are competitive without being class-leading.

The X-Trail e-Power returns the same 6.1L/100km, but the RAV4 Hybrid uses just 4.8L/100km so there’s room for Hyundai to close the gap.

But at 6.1L/100km the hybrid would be the most fuel-efficient member of the Tucson range in Australia, with the diesel managing 6.3L/100km and the 1.6 turbo petrol using 7.2L/100km. So there’s reason to think adding this hybrid option would expand the appeal of the Tucson.

The US-spec models have a 51-litre fuel tank which means a theoretical driving range of up to 835km on a single tank.

Again, it would be easy to think that the QX30 would feel almost identical to its lower-riding sibling – but that would be incorrect. We criticised the Q30 for being a bit too buttoned down and unresponsive, but the QX30 feels more lively and involving, thanks to its unique spring and damper set-up.

Even though it’s 30mm higher than the Q, the QX doesn’t feel it at all, with a benign, pleasant ride with good body roll control and competent steering.

Our front-seat passenger complained of feeling a little ‘hemmed in’, which is a valid point. The sides of the car are very high, and the roofline is quite low, exacerbated by the steeply raked windscreen.

The 2.0-litre four-potter is smooth and punchy, and the gearbox well suited to it, but it’s lacking in aural character. Luckily the QX30 does a terrific job of suppressing noise before it gets into the cabin, then…

The extra power and torque makes for a notable improvement in performance over what’s currently offered in Australia. The Tucson Hybrid feels quite punchy off the mark whenever you engage both the engine and motor. While it’s not exactly a ‘N Performance’ model, it does feel sprightly for a mid-size SUV.

Plus there’s the added bonus that the electric motor can do all of the work some of the time.

So if you do a lot of urban driving and can be careful with your right foot you may be able to get close to, or even beat, the claimed fuel economy.

It’s difficult to make a definitive comment on the handling, because the version we drove had the US suspension tune, which felt softer than what we’ve experienced here to deal with America’s very average road conditions. Even so, our test drive did demonstrate that the addition of the hybrid system, and the added weight it brings, doesn’t have a negative impact on the way the Tucson drives. It still feels like a well-balanced and responsive SUV and we’d certainly expect that to be the case of Australian-bound models.

Again, this is an area where we don’t know any specific details, but it’s almost certain that the Tucson Hybrid will follow the same safety features as the rest of the range.

There’s all the usual acronyms you expect these days, such as AEB (autonomous emergency braking), ESC (electronic stability control), BSM (blind spot monitoring) and RCTA (rear cross-traffic alert).

The biggest difference between the current range and the hybrid is likely to be the loss of the full-size spare wheel. Given the unique Australian conditions, if Hyundai can find a way to fit even a spacesaver spare it would be more appealing and safer than the puncture repair kit.

The addition of an all-new engine variant typically requires a new crash testing program under the ANCAP safety ratings, but the rest of the Tucson range is five stars and there's no reason to think the hybrid would be dramatically worse.

The Q30 is offered with a four-year, 100,000km warranty, and servicing is suggested every 12 months or 25,000km.

Infiniti offers a fixed three-year service schedule, with the GT and the Premium both costing an average of $541 over the three services provided.

It’s safe to assume that Hyundai Australia will offer its standard five-year/unlimited kilometre warranty for the Tucson Hybrid. 

Servicing costs are unclear but it’s probable that the more complex hybrid powertrain would mean a higher price. But Hyundai Australia will likely offer a servicing plan, so you’ll know up front what you’re in for.
