Diesel

Fuel prices continue to increase in Australia.Hybrid models generally offer better fuel efficiency than a comparative petrol model, but they are also more expensive. Questions remain about how much going hybrid actually saves buyers on fuel and how long it will take to pay off the extra upfront cost. Below is a comparison based on some of the most popular models in Australia offering petrol and hybrid choices and the potential increased savings in the current climate. Figures have been calculated based on the average yearly kilometres driven at 15,000km, and the cost to fill-up based on average NSW pricing data using the official recommended fuel for each model. Small car/sedanHyundai i30 sedanThe Hyundai i30 is one of few passenger car models which are available with petrol and hybrid variants in its lineup. Many of its rivals have become hybrid only, such as the Toyota Corolla and Camry as well as the Honda Civic. The hybrid is cheaper to fill up and goes further on its tank, so it takes around four years to pay off the $4000 hybrid premium - well within the seven-year warranty period for the car. This is also due to the smaller and more efficient hybrid motor compared to the bigger petrol engine.Small SUVChery Tiggo 4 The Chery Tiggo 4 is one of the cheapest SUVs on the market, with a drive-away price under $30,000 for both petrol and hybrid variants. The Hybrid carries a $6000 premium over the petrol, which means it will take roughly seven years to pay off the extra cost. This is part due to the $850 year-on-year saving, which is less than many of the other cars on this list. Unlike the other examples, there is no change in engine capacity between petrol and hybrid variants of the Tiggo 4.  The seven-year break-even point matches the seven-year warranty provided on the car. Medium SUVGWM Haval H6There is a $5000 gap between pricing on the petrol and hybrid versions of the Haval H6, but the smaller and more efficient hybrid engine sees savings of more than $1000 year-on-year. The H6 hybrid offers an average of more than 500km of driving range than the petrol. This means the extra cost of the hybrid can be paid off in just under five years. This falls within the seven-year warranty period for the H6. Large SUVHyundai Santa FeThe Hyundai Santa Fe was CarsGuide’s 2026 Overall Car of the Year, and offers one of the most competitive hybrid/petrol pricing comparisons. This is because the hybrid Sante Fe is less than $4000 more expensive than the petrol and offers more than 400km average driving range. With nearly $1200 of savings each year, it would take around three years to pay off the hybrid premium, and the majority of the car’s seven-year warranty will also still be valid.UteThis comparison uses the cheapest dual-cab variant of the Toyota HiLux Workmate and the single-variant BYD Shark 6. While these utes are obviously not variants within the same lineup, the Shark 6’s petrol status offers savings over the diesel ute. It also has a smaller fuel tank, which makes filling up cheaper. The HiLux is also slightly more expensive to drive-away, costing about $59,500 in NSW.Fuel efficiency on the Shark 6 dramatically decreases when the ute has less than 25 per cent of battery charge, dropping to 7.9L/100km. This still makes it less expensive to run than the diesel HiLux. *Petrol engine only fuel use figure not provided by Ford but calculated over several CarsGuide road tests once battery had been depletedThe plug-in hybrid set-up in the Canon Alpha does make it cheaper to run overall, but the substantial price difference between the plug-in hybrid and the petrol, means it would take eight years to break even on the extra cost. The Ranger PHEV is more of a curve ball, it is harder to hit on exactly how much fuel it will use. It all depends on how ofter you charge the battery. If you don't charge it every night it'll be more expensive to run than the diesel, as it needs to be topped up more often. If you regularly charge it the cost equation flips and it's a wallet saver.You'll need to be vigilant about charging to pay off the $15,000 premium, though.

The third-generation Mitsubishi Outlander mid-size SUV was popular in Australia for good reason, with it offering buyers the choice of five or seven seats, and plug-in hybrid, petrol or diesel powertrains. As a result, it can also make for a good used car.

Volkswagen Australia is adding two new V6 turbo-diesel variants to the dual cab ute’s local line-up, with the 2026 model year range becoming an almost exclusively 3.0-litre V6 offering.Volkswagen says it has been “guided by feedback from owners, dealers and enthusiasts in placing stronger emphasis on V6 powertrains, while simplifying the range to make choosing an Amarok clearer and more intuitive than ever.”But it’s worth noting, as with its co-developed Ford Ranger ‘twin-under-the-skin’, the 154kW/500Nm 2.0L twin-turbo diesel four from the Amarok Life and Style models has been squeezed out of existence by tightening emission regulations.And, unlike Ford Australia, VW has also made the call to phase out the 125kW/405Nm 2.0L single-turbo four-cylinder diesel, currently offered in the entry-grade Amarok TDI 405 Core.To help pick up the slack, the first of the Amarok’s new 184kW/600Nm 3.0L turbo-diesel entries is the Dark Label V6.Limited to 200 examples, it adds visual drama and a lengthy standard equipment list to the VW ute formula, including:20-inch ‘Matte Black’ ‘Bendigo’ alloy wheelsLED matrix headlights (with black surrounds)Darkened tail-lightsBlack sports bar, side steps, rear bumper, door handles and mirrorsFront bumper ‘X‑design’ in blackBlack front skid plateMatte Black B‑pillar foilRoof rails in Matte BlackSpray‑in tub linerBlack tonneau coverDark Label sticker pack (bonnet, doors, tub sides, tailgate) Pricing and exact arrival timing are yet to be confirmed, but it’s likely to hit showrooms before the end of 2026.Then, in the second quarter of this year, the Amarok W600 special edition will deliver another premium performance option.Locally-developed by Walkinshaw Automotive Group in Melbourne and based on the TDI600 Style, it features the 3.0L turbo-diesel V6 as well as a multitude of dynamic upgrades including a bespoke Koni suspension set-up, 20-inch six-spoke alloy wheels, a full-width LED light bar and (lots) more.Volkswagen believes it will “reinforce Amarok’s position as a leader in driving feel and performance within the dual‑cab segment.”And finally, the 222kW/452Nm 2.3-litre turbo-petrol four-cylinder powered Amarok Style TSI452 replaces the previous Aventura TSI452 with spec upgrades including: Permanent all‑wheel driveSix drive modesOptional 20-inch ‘Bendigo’ alloy wheelsFor reference, the current Amarok Aventura TSI452 is priced at $79,990, before on-road costs.Volkswagen’s Australian Amarok line-up for MY26 (with pricing yet to be confirmed) will be:Amarok Style 2.3 TSI452Amarok Style 3.0 TDI600Amarok Style (w/ Tray) 3.0 TDI600Amarok PanAmericana 3.0 TDI600Amarok Aventura 3.0 TDI600Amarok Dark Label 3.0 TDI600Amarok W600 3.0 TDI600

Why does my 2022 Mazda BT-50 diesel manual idle at around 1000rpm most of the time and shudder when I turn it off?

Diesel isn't dead after all: Why the owner of Peugeot and Jeep is making up for lackluster EV sales with diesels.

To torture a well worn Mark Twain reference, if Australia’s 2025 new vehicle sales numbers are anything to go by, reports of the diesel engine’s death are greatly exaggerated.According to Federal Chamber of Automotive Industries VFacts registration data, for the full calendar year of 2025 diesel-powered vehicles across passenger, SUV and light commercial segments totalled 364,605 units, only 1.7 per cent lower than 2024’s overall number (370,818).In fact, sales of diesel-powered passenger cars were up 1.3 per cent year-on-year (10,372 vs 10,242) with diesel SUV sales rising no less than 6.0 per cent (122,603 vs 115,670).Diesel light-commercial sales were down 5.4 per cent (231,630 vs 244,906) while plug-in hybrid commercials went from zero in 2024 to 20,634 last year.A coincidence that 18,073 examples of BYD’s Shark 6 PHEV dual cab ute found homes last year? We think not.The Ford Ranger was the best selling vehicle in 2025, but it wasn't alone at the top.Traditional diesel-heavy sellers the Toyota HiLux, Isuzu D-Max, Ford Everest and Toyota Prado filled the third to sixth slots on the 2025 overall sales leader board with others such as the Mitsubishi Triton lifting year-on-year volume, too. Only the second placed Toyota RAV4 Hybrid managed to break up diesel's dominance atop the new car sales charts last year.Of course, nothing stays the same forever and given the rapidly shifting form of the Australian new vehicle market and the increasing impact of the federal government’s New Vehicle Efficiency Standard (NVES) regime there’s a chance the diesel engine’s status may have changed dramatically by the end of 2026.But for now, it appears diesel power isn’t headed for the automotive graveyard just yet.  Australian diesel vehicle registrations:

South Korea’s KGM (formerly known as SsangYong) has officially revealed the design of its new-generation Musso dual-cab ute ahead of more details surfacing in the new year.Dubbed the ‘Q300’, this generation of the Musso dials up the style factor with glitzy looks that are similar to the current Actyon- and Torres-based Musso EV.The front particularly is busy with lots of design elements. KGM has shown off two grille designs, but both feature big LED headlights that are joined by a full-width LED daytime running light set-up.Around the side there is plenty of thick black cladding around the wheel arches and the door sills. There are also vertical accent strips at the top of the wheel arches, like the Musso EV.At the back there is a step into the tub, vertical tail-lights, KGM embossing on the tailgate, as well as a complex sports bar.Beyond this KGM hasn’t provided any further details. It appears this new-generation ute has a body-on-frame chassis, though it’s unclear how much has been altered compared to the outgoing generation.Globally this new Musso will be offered with petrol and diesel powertrains, though no specifications or outputs have been announced yet.The current Musso is offered with a 2.2-litre four-cylinder turbo-diesel engine that produces 133kW and 420Nm. In other markets there’s also a 2.0-litre turbocharged four-cylinder petrol engine available.KGM plans to launch this new-generation Musso in the domestic market in the first quarter of 2026.It’s unclear when it will be coming to Australia. We’ve reached out to KGM Australia and will update this story once we hear back.The Musso name dates back all the way back to 1993 when it was adorned on an SUV. It later spawned a dual-cab ute version in 2002 called the Musso Sports.The outgoing version of the Musso, dubbed the Q200 generation, dates back to 2018. It has received a number of updates over the years, including one that launched in Australia earlier this year with the availability of electric power steering among other safety feature additions.It also saw SsangYong dropped from the name altogether.Given there is a new Musso that’s now been revealed, it’s unclear whether a new-generation Rexton SUV is also on the horizon. The two vehicles have historically been based on the same platform and share a lot of componentry.

Nissan to unveil long-awaited next-gen Navara imminently!

Diesel engines are far from over, with a big new 3.0-litre unit is destined for one of Australia’s emerging range of utes and SUVs. To make its global debut in Australia sometime in the middle of next year, this internal combustion engine with no electrification assistance will arrive in an in-line four-cylinder turbo-diesel configuration that promises to be one of the most efficient of its type available anywhere in the world.

Diesel as a fuel source might not be dead yet, but the vultures are circling, waiting for their prey to finally stop moving. Don’t believe me? It doesn’t take a crystal ball to see into a future already so clearly laid out, and not just by newcomer brands, but by some of the biggest proponents of diesel engines in the history of the fuel.
