Kia K4 Hatch to debut more efficient engine in Australia
Speaking with CarExpert at the Australian media launch of the updated Sportage mid-size range, Kia Australia's general manager for product planning Roland Rivero wouldn't be drawn on the local prospects for the K4 Hybrid (HEV), which is yet to be revealed, but he did confirm a more efficient drivetrain is coming to the core K4 lineup.
'We've got [the] hatchback first – the K4 Hatch. That does adopt a new powertrain which you're familiar with from the Seltos… which helps us out from a CO2 perspective – that will be our first adjustment in light of NVES [the federal government's New vehicle Efficiency Standard],' Mr Rivero said.

The powertrain in question is the Atkinson-cycle 2.0-litre four-cylinder petrol engine mated with what Hyundai and Kia call an 'IVT' or Intelligent Variable Transmission. Effectively, it's Hyundai/Kia-speak for a CVT.
As Mr Rivero mentioned, this drivetrain is already on sale locally in the Seltos small SUV, and also serves in the related Hyundai i30 Sedan and Kona crossover.
Due to its more efficient Atkinson cycle, the new engine makes slightly less grunt than the existing 2.0-litre 'MPI' engine (110kW/180Nm versus 112kW/192Nm) but is claimed to be more fuel-efficient, helped in part by the different transmission.
'The CO2 on that is better than even the 1.6 turbo – I think it's about a 30g/km improvement [over the 2.0L MPI]. Whether we spec it with [idle stop/start] is TBC,' Mr Rivero added. K4 Hatch Credit: CarExpert
The current 2.0L MPI engine with a six-speed automatic in the K4 Sedan quotes combined fuel consumption of 7.4L/100km and CO2 emissions of 167g/km, while the more powerful 1.6 T-GDI engine in the GT-Line with its eight-speed auto quotes 6.7L/100km and 158g/km.
For reference, the related Hyundai i30 Sedan with the Smartstream-branded Atkinson-cycle engine and CVT quotes a much thriftier 6.1L/100km and 139g/km of CO2 on the combined cycle.
Mr Rivero said the new drivetrain will be applied to both the upcoming K4 Hatch as well as the existing K4 Sedan during the fourth quarter of 2025, likely coinciding with model year 2026 (MY26) production.
As yet there's still no word on a K4 Hybrid or HEV variant, which has been all but confirmed for a future introduction. It will almost certainly draw upon the 1.6-litre hybrid system used in the i30 Sedan and Kona hybrids, which makes 104kW and 265Nm. K4 Sedan Credit: CarExpert
Since launching earlier this year, the Kia K4 has managed 1892 registrations to the end of May. By comparison, its top-selling predecessor, the Cerato, managed 6323 registrations during the January-May 2024 period. But last month, the new sedan-only K4 outsold the outgoing Cerato hatch and sedan with 577 sales versus just 68, which was nevertheless short of segment leaders including the Toyota Corolla (1576), Hyundai i30 (909) and Mazda 3 (735).
However, the K4 currently lacks an ANCAP safety rating, which is a requirement for many of the large fleet customers that account for a large proportion of small car sales across the industry, so the addition of a more popular hatchback body style and an independent safety rating should give the K4 a significant shot in the arm.
'It's taken a few months… but now [the K4] is starting to build momentum. Once it gets its ANCAP rating, it will open the door to fleets,' said Dean Norbiato, general manager for marketing at Kia Australia.
'Then we get the hatchback. We are a hatch-biased market, so when that comes at the back end of the year we're really confident in that product taking over a really important model in the Cerato, and that hatch in particular will definitely meet the demand and appetite of the Australian market as well.'

How India ties into Suzuki Australia's EV plans
Suzuki Australia is gearing up for an onslaught of electrified vehicles, and it says its parent company's Indian operations will be key to getting such cars into local showrooms. Maruti Suzuki is an Indian subsidiary of the Suzuki Motor Corporation, and its largest subsidiary in terms of production volume and sales. Founded by the Indian government in 1981 as a joint venture with Suzuki, Maruti Suzuki became wholly owned by the Japanese manufacturer in 2007. Since then, it has been responsible for producing countless Suzuki models for domestic and export markets, including Australia. These models have included the Baleno, the current Jimny XL, and now the Fronx Hybrid. 'It's essentially the same brand. We are Suzuki. They are Suzuki. They are part of the organisation,' Suzuki Australia general manager Michael Pachota told CarExpert. CarExpert can save you thousands on a new car. Click here to get a great deal. 'And we control the future of products from a global perspective, the Suzuki Motor Corporation, that's the mother company. That being said, from a production perspective, the opportunities are endless. 'Some of our newest, most state-of-the-art production plants are in India now, based on the fact that, you know, they're probably running out of space in Japan.' Maruti Suzuki operates four manufacturing facilities, with two in the state of Haryana, located in northern India. One is its Gurugram plant, a 300-acre facility responsible for producing Indian examples of cars like the S-Cross and Ignis, as well as the Australian-market Jimny. The other is the Manesar plant, a larger, 600-acre facility responsible for producing the Australian-market Baleno up until the model's local axing in 2022. Combined, these two plants have a claimed annual production capacity of 1.5 million units. A third is Suzuki Motor Gujarat, located in western India. This facility opened in 2017 and has a total annual production capacity of 750,000 units across its four plants, one of which is a dedicated engine and powertrain plant. Produced in Gujarat are Australian examples of the mild-hybrid Fronx. Incoming models, like the eVitara, Suzuki's first fully electric vehicle (EV), began production at the Gujarat facility in April this year and will be sold in Australia from early 2026. Other Australian models, like the Swift Hybrid, are built in Makinohara, Japan, while the incoming Vitara Hybrid – related to the eVitara in name only – is built in Esztergom, Hungary. 'With that said, you've got to tailor to the market and be in good positions where you can distribute vehicles from an export perspective, and India is a perfect place to do so,' Mr Pachota told CarExpert. 'We have 100 Japanese staff over there doing quality control all the time as well. It doesn't matter what plant the vehicle is manufactured in, the quality will always remain undeniably Suzuki.' Additionally, Maruti Suzuki began production at its newest facility in Kharkhoda, Haryana, in February 2025, with an initial annual capacity of 250,000 units. The company has predicted this plant will become the world's third-largest car manufacturing facility once fully operational. Maruti Suzuki is also building a second manufacturing plant near its Gujarat facility with an annual production capacity of 1 million cars, which, once up and running in 2029, could serve as a launchpad for future EVs after the eVitara. 'The opportunities for EVs … eVitara will be manufactured in India, so that's the first step towards that goal,' Mr Pachota added.

How much Volkswagen is in Lamborghini's newest supercar?
The 2026 Lamborghini Temerario supercar still benefits from broader Volkswagen Group expertise – despite there no longer being an Audi equivalent – according to the raging bull brand's chief technical officer, Dr Rouven Mohr. Due in Australian showrooms in the first half of 2026, the Temerario will be priced from $613,885 before on-road costs, sitting below the flagship V12 Revuelto, launched this year from $987,908 before on-roads. The Temerario uses a twin-turbocharged 4.0-litre V8 petrol spinning to 10,000rpm and three electric motors as part of a hybrid setup, enabling a rapid 2.7-second 0-100km/h sprint and 343km/h top speed. The new supercar replaced the Huracan as the entry-level Lamborghini, which was powered by a 5.2-litre naturally aspirated V10 petrol engine also used in two generations of Audi R8 supercar. CarExpert can save you thousands on a new car. Click here to get a great deal. The Huracan – like the Gallardo before it – was twinned to create the Audi R8 supercar for the fellow Volkswagen Group brand, giving both brands credible road-going models and sports car (GT3) racing competitors. Production of the R8 commenced in 2006 and ended in 2024. Yet the Temerario is the first entry-level Lamborghini for three generations not to share its underpinnings with Audi – making it the first since the 1988 Jalpa – with the German brand quitting sports car racing to join the Formula One grid in 2026. This doesn't mean the Italian brand was left to develop the Temerario alone given there's no Audi-equivalent this time around – but nor is it a Volkswagen parts bin special, either. 'This [being part of the Volkswagen Group] is an absolute strength,' Dr Mohr, Lamborghini's chief technical officer, told CarExpert. 'For sure, we are discussing synergy [with other VW Group models], this is clear … [but] for me, I'm fully convinced the Volkswagen company is the only group that lets the brands lead their own events.' The Lamborghini tech boss explained developing parts which have limited impact on the customer's experience is not an intelligent business approach. 'It simply doesn't make sense, to be honest – what is the differentiation factor, addition value for the for the customer, for [separate development of] the climate control?' he said.'But if you look at the at the product defining components – and I can give you also really specific examples on the car – we have the full freedom for sure.' The Temerario is loaded with 'product defining components', as Dr Mohr puts it. 'The electric front axle was a standalone development … the battery is a standalone development – we are using only in the [VW] Group cell, because we are not developing cells, chemical cells, but the battery assembly and so on [is Lamborghini].' 'Cooling concept is Lambo. Gearbox is only Lambo. Engine – people think it's based on the [Lamborghini] Revuleto [V12] engine – it has nothing to do with the Revuleto,' Dr Mohr explains. 'Because if you want to rev 10,000rpm, to be honest, you cannot start with the standard V8. You can reach a 10,000 because you start everything based on the mechanical configuration of the engine with this [10,000rpm] point [in mind], so this is completely standalone.' The V8 includes a 'hot vee', the term used to describe turbochargers mounted within the 90-degree cylinder banks, which again aren't taken from another Lamborghini or Volkswagen Group powertrain. '[The Revuleto's] turbochargers are not used [the Temerario's are smaller for better response], but there is a pump for the cooling circuit – something like that is carryover – but the rest is standalone,' the tech boss explained. 'This [synergy], I have to say, is one of the strengths. As an organisation, we became focussed on the differentiation … we could balance what is important for the brand and what is make or break to make a difference'

Suzuki's flagship SUV hanging on, but for how much longer?
Production may have ended for Suzuki Australia's largest and most expensive SUV, but the brand insists there's still plenty of stock for prospective buyers. The S-Cross was one of five Suzukis to fall victim to updated Australian Design Rules (ADR) that outlined specific performance requirements for autonomous emergency braking (AEB) systems. This change also affected several Mitsubishi models. Suzuki Australia announced production of the S-Cross ended in February 2025, ahead of the introduction of the new rules on March 1, 2025. Know the news with the 7NEWS app: Download today Since then, there has been no confirmation on whether shipments of the S-Cross would resume with a compliant AEB system, though separate distributor Suzuki Queensland said it was axing the model. However, Suzuki Australia general manager Michael Pachota says the model is not yet extinct in showrooms. CarExpert can save you thousands on a new car. Click here to get a great deal. 'From an S-Cross perspective, based on our current inventory, we still have a long sales journey based on what we can supply and what we can sell,' he told CarExpert. 'So we're still re-evaluating that position, but we haven't made a decision yet on S-Cross' future per se. 'We'll continue selling it until we haven't got it, maybe.' Mr Pachota's vague wording doesn't inspire confidence for the resurrection of the S-Cross, at least as we know it. This isn't surprising, given the S-Cross was comfortably Suzuki's lowest-volume model in its final two full years on sale. In 2023, it chalked up 598 deliveries, below the 2016 posted by the next-closest Vitara, and followed it up with 706 in 2024, still down on the 1815 recorded by the Ignis. Production for the Vitara and Ignis also ended for Australia when the ADR axe fell. The current, Hungarian-built S-Cross, launched here in 2022 as a significant update of a model that entered production in 2013. Suzuki Australia had previously confirmed it would bring a hybrid version of the S-Cross to Australia in 2024, but this never eventuated. The outgoing car is still available on Suzuki Australia's website in both MY23 and MY24 guises, starting at $33,290 and $36,990 drive-away respectively. As for the Vitara, which was axed by the separate Suzuki Queensland entity, Suzuki Australia has confirmed an updated Vitara Hybrid and new electric eVitara will launch in early 2026. The latter will be Suzuki's first-ever fully electric vehicle (EV). When asked about early indications for the Vitara Hybrid, which has yet to be confirmed with either mild- or strong-hybrid power, Mr Pachota said he believes 'the Australian consumers are ready for a hybrid Vitara'.
