Diesel

BMW believes there's no such thing as too much choice with its all-new fifth-generation BMW X5.Why else would it go ahead and develop no less than five different powertrains that include a mild-hybrid petrol and diesel, plug-in hybrid, all-electric and, from 2028, a hydrogen fuel-cell?On sale in Australia late this year, the new BMW X5 is the third member of the German brand's Neue Klasse family of next-generation vehicles, lining up alongside the mid-size iX3 and more recently unveiled i3.Like the electric mid-size SUV and sedan, it adopts the firm's latest design language that sees the large SUV embrace striking monolithic proportions, a bold front end with the Neue Klasse visor and a large pair of illuminated vertical kidney grilles.You won't miss it in a car park.If you don't dig the double X LED running lamps, BMW says you can dial them back to double strikes, while the lamps themselves neatly integrate the indicators and provide a clean, imposing look.Along its flanks, the simple surfacing and a lack of any jarring door handles reinforce the X5's imperious stance, while muscular arches and large wheels that range from 21 to 23-inches mean this isn’t an SUV for shrinking violets.Measuring in at 4994mm long, 2000mm wide and standing a towering 1742mm, with a substantial 3035mm wheelbase, some family owners might lament the loss of both the handy split tailgate and the option of a third row of seats, with both the X5 and iX5 strictly five-seaters.Grab the door winglets and the front doors swing open automatically, like they would in a 7 Series limo or a million-dollar Rolls-Royce.Inside, the luxurious Mercedes GLE or Audi Q7 rival picks up where the iX3 left off, boasting the same Panoramic Vision that features a digital strip display that stretches across the entire top half of the dash.Complementing the configurable strip is a large 3D head-up display and a massive 17.9-inch infotainment touchscreen that can be combined with a passenger screen.Helping compensate for the lack of physical controls is a multifunction steering wheel that provides haptic feedback when in use.All the in-car tech runs the car-maker's latest OS X software that now embed Amazon Alexa AI tech within its handy virtual assistant.As well as a striking design, the X5 features a blend of new high-grade leathers and a fresh choice of natural materials, that even include slate for the first time around the gear lever.Helping BMW's latest X5 offer a wide range of powertrains, the large SUV misses out on the brand's next-generation Neue Klasse platform that is reserved for EVs.Instead, the new SUV sits on an upgraded version of the current car's CLAR underpinnings.Even though it misses out on the more advanced architecture, the all-electric iX5 still comes with BMW's latest sixth-generation eDrive powertrain that uses cylindrical cells that have a 20 per cent higher energy content than before.Sharing the same 800-volt electrics as the BMW iX3, the bigger SUV boasts a class-leading 800km range. The German brand says its unbeatable distance between charges comes from efficiency gains, although we think the enormous 140kWh battery does most of the heavy lifting.Plug it in and the charging rate is said to exceed 450kW, with a 10 to 80 per cent charge set to take less than 25 minutes.Add a tow hook and the iX5 can haul up to 2700kg (braked) – not too far off the maximum 3300kg the PHEVs can tow.Impressive, but it's worth mentioning the EVs won't arrive until late 2027.If you can't wait until then or you're not ready for an all-electric revolution, BMW will offer a pair of mild-hybrid combustion engines that combine a 3.0-litre inline six-cylinder with a 48-volt integrated starter-generator, plus an eight-speed transmission and all-wheel drive.The X5 40 xDrive produces 294kW and 540Nm of torque, which is enough for a 0-100km/h dash of 5.4 seconds. The second turbo-diesel, the 230kW/670Nm X5 40d xDrive takes 6.2 seconds for the same sprint but can also average a more miserly 7L/100km (versus 8.6L/100km for the petrol).For Australians, the two plug-in hybrid (PHEV) versions might be a perfect compromise when they arrive in the second half of next year.Both the PHEVs blend an EV range of up to 100km with either 360kW (X5 50e xDrive) or 450kW for the X5 M60e XDrive that takes just 4.2 seconds to launch from 0-100km/h.Until the sportiest twin-turbo V8-powered X5 M arrives, the flagship PHEV and advanced iX5 60 xDrive remain the sportiest variants, with the latter dual motor EV pumping out 425kW and 805Nm of torque for a 0-100km/h sprint of 4.7 seconds.BMW will release full details of the iX5 Hydrogen later, which comes equipped with a third-generation fuel-cell that has been developed with help from Toyota.With plenty of praise already heaped on the BMW iX3, the German brand says its latest Neue Klasse SUV will blend best-in-class handling with high levels of comfort.Included in its dynamic repertoire is the same powerful Heart of Joy superbrain that seamlessly manages torque and all the chassis tech.Whichever you buy, all X5s come with a 50:50 weight distribution, air suspension and rear-wheel steer.A more sophisticated Adaptive Chassis height-adjustable suspension is also available, plus a further semi-active suspension that cancels out body roll for the most comfortable ride.Driver assist tech includes hands-free highway driving and a city assistant driverless mode that helps with working out who has right of way in unfamiliar cities.BMW Australia says it's too early for full details and pricing for the BMW X5 or iX5 but the new fifth-gen large SUV lands it is tipped to be priced from $150,000 plus on-road costs when sales begin at the end of this year.

Hyundai has just updated its Staria people mover and despite the imminent arrival of new electric and hybrid variants, is this diesel workhorse version still worth considering?

Will the current war in Iran mean a ban on petrol and diesel vehicles? My view is no, it won’t directly cause a ban on combustion cars. But the ban is still coming and the Middle East conflict will fastrack it. For starters a date has already been set for ban on petrol and diesel cars in the United Kingdom, where from 2030 sales of new vehicles with combustion engines will cease. The European Union has a 2035 ban but previous to the Iran war this was watered down.China, which in February was our main source of vehicles, is also focused on building and developing electric cars.As for Australia, only the ACT has set a goal of phasing out the sale of new combustion powered cars by 2035.That could all change now and by this I mean be fastracked.Until now the reasons for switching to electric vehicles were mainly ethical and environmental, with emissions and cleaner air being the carrot. The problem is nobody really  wants to eat a carrot, even if it’s good for us. But faced with the prospect of not eating at all because the weekly fuel bill for two cars is now $300 and the price of groceries is going up because of the soaring cost of transport, that really changes things.Interest in electric vehicles has never been this strong. We can see it in real time by the traffic coming to carsguide.com.au and we know our competitors are witnessing the sharpening of this focus on EVs, too.Towards the start of 2025 there had been a slow down in global interest in EVs and a renewed take up of hybrids. The price premiums attached to electric cars, the limited driving range and lengthy charging times were to blame, but all things early adopters, and even slightly later ones, were willing to endure. The rest of the car buyers were too put off by the downsides of EVs and stuck with the convenience and familiarity of petrol or perhaps bought a hybrid. But now the price of convenience appears to be reaching a point where suddenly an EV sounds like a good idea. At the time of writing 95 RON premium unleaded was $2.70 per litre. An increase of about $1 per litre or 60 per cent in the space of a month. The prohibitive cost now of petrol combined with the looming threat of Australia running out of it in less than three weeks, plus reports of servicing stations already running dry now make an electric car suddenly seem like not such a bad idea after all, even to the most hardcore fans of fossil fuels.The problem is bigger than just consumers not being able to afford petrol, it’s the soaring cost of goods, which are distributed through Australia’s enormous freight network that relies on diesel.The Australian government is responsible for setting such low minimum fuel reserves all in the name of a free market. The current situation could see it either mandate that the industry maintain a higher level or reduce the risk entirely of being held hostage like this again and ban petrol and diesel car sales in favour of electric ones, which can be powered by a fuel we can produce ourselves.The second option wouldn’t be the choice of the $6 trillion-a-year global oil and gas industry. And an industry that’s worth that much has enormous sway.But then the collapse of entire economies wouldn’t be the choice of most governments.Decoupling from oil and gas is impossible in less than 50 or even 100 years. Whether we like it or not the industry pervades every part of our lives. Killing the industry would also see the collapse of entire economies.Plenty of car companies are ready for electric vehicles, especially new Chinese brands, but for many vehicle manufacturers EVs are a side hustle.This scenario play into the hands of new electric brands such as Zeekr with the 7X mid-szied SUV, BYD with the Sealion 7 SUV and even the established Koreans such as Kia with the EV3 small SUV.Does it mean the end of diesel SUVs such as the LandCruiser? Possibly, unless Toyota has an electric version up its sleeve ready to be pulled out in the next 10 years.So what you'll probably see is the EU and UK setting new firm deadlines for the discontinuation of sales for new cars with combustion engines at about 2035 or sooner. Australia will likely follow suit.Industry, freight and agriculture will be exempt until hydrogen infrastructure is in place and that will take much longer.What we may see in the short term is a temporary ban on the use of petrol and diesel passenger cars in order to preserve fuel stock for industry, freight and vital services such as emergency vehicles. That’s a real possibility if the war moves into an uncontrolled phase.So while the permanent ban of new petrol and diesel cars won’t be directly caused by the Iran war, it will be a catalyst for the ban. In the meantime, it’s probably wise anyway to purchase an EV anyway and provide a bit of security and future proofing for your own household, not to mention saving thousands in fuel bills each year.

Fuel prices are soaring across the board whether it is petrol or diesel. Some drivers are being more affected than others as lower fuel efficiency contributes to higher refuelling costs. Here are the most expensive cars to run currently in Australia based on fuel efficiency. Other contributing factors to the high fuel costs on this list include the fact many of the cars have big fuel tanks and require premium fuel.Fuel prices have been calculated using the average prices for fuel in New South Wales and at an average of 15,000km driven per year. Among the heaviest guzzlers is the Nissan Patrol four-wheel drive, with its 5.6-litre V8 drinking fuel at a rate of 14.4L/100km. Its 140-litre fuel tank and requirement for premium unleaded petrol means it costs $364 per fill-up and a total yearly cost of $5617.28. The Patrol will move to a more efficient 3.5-litre six-cylinder twin-turbo petrol, which is expected to reduce fuel costs. The Ford Mustang sports car is another V8 on this list, with its 5.0-litre unit registering average fuel efficiency at 13.6L/100km and a yearly cost of $5310.27.Ford’s other representative is the Ranger Raptor high-end ute, powered by a twin-turbo six-cylinder petrol engine costing $4482.76 per year. The Ineos Grenadier off-roader is the most expensive model to run and costs $5618.50 a year to run, in part due to it being diesel, which has been the fuel type that has increased the most. The Lexus GX550 has refuelling costs of $208 per fill-up currently, costing $4800 for the year, along with nearly $3000 for the Jeep Gladiator, which unlike many on this list can run off E10 fuel.The 6.2-litre petrol V8 found in the Chevrolet Silverado full-size pick-up has an economy of more than 12 litres per 100km, costing $4,356.30 over the year.  Genesis’ GV70 luxury SUV costs more $4400 per year in fuel, a similar figure to the supercharged 5.0-litre V8 variants of the Land Rover Defender. Highest fuel efficiency new vehicles on sale under $150,000 

Diesel utes have been the dominant forces in Australia for the past decade, but that could be about to change.The Ford Ranger and the Toyota HiLux have been the top two sellers in the past 10 years, and they combined for more than 100,000 sales in 2025.The pair have carried on this popularity into 2026, sitting at the top for January and February this year. Other diesel ute rivals such as the Isuzu Ute D-Max and Mitsubishi Triton are selling well. That could be all be about to change sooner than we thought. It could be the case that a perfect storm of external factors will wipe out the diesel in ute in Australia.There is a new factor is emerging that could accelerate the diesel ute’s seemingly inevitable decline. The price of diesel fuel has increased substantially more than petrol, approaching the $3 mark per litre.I went to fill up my diesel car the other day.As I pulled into the service station, a man had just finished filling up his V8 diesel LandCruiser 200 Series. $287 for 99L - he had not even brimmed the tank. You’d get a better rate when topping up your light aircraft with aviation fuel. He asked if I wanted to swap. I politely declined.No doubt big fleet buyers will be watching closely as the costs of purchasing and running these diesel utes shoots up, along with the potential increase in costs as NVES pressures creep in. Fleet sales are crucial to the success of the Ford Ranger and the Toyota HiLux, with them also contributing heavily to other ute brands.Fuel prices will also be an increasingly big head turner for private buyers. Alternatives such as the petrol plug-in hybrid BYD Shark 6 offer superior fuel efficiency when charged as well as being cheaper to fill up.Toyota announced its all-electric HiLux ute recently, which has been met with a mixed reception due to concerns over driving range and towing capacity, but it at least shows brands are already looking away from diesel. Chery’s incoming KP31 ute will debut in Australia this year with a diesel plug-in hybrid set-up, which is expected to have the 3500kg towing capacity. Something the Shark 6 currently lacks.The popularity of diesel hybrid set-ups will be an indication of the survival chances for the diesel ute in Australia. It could be argued the longer diesel prices continue to rise, the shorter the diesel ute's lifespan will be.Compounding this is new emissions laws.The Federal Government's National Vehicle Emissions Standard (NVES) delivered a rude awakening for some. The NVES sets emissions targets based on CO2 gram-per-kilometre limits. Vehicles sold that fall over the limit subsequently incur liabilities, which will attract hefty fines in the future for brands. Brands incur fines on vehicles sold, which have an interim emissions value of more than zero. Mazda, which sells its BT-50 ute in Australia among an internal combustion heavy lineup, accumulated a whopping more than 500,000 liabilities. Subsequently many brands, including Honda and Mazda have introduced priced increases across key internal combustion models this year.There appears to be two routes for brands. Either pass on the extra costs, or ditch diesel. Diesel utes could be about to skyrocket in price and brands scramble to account for fines on sales.In a more extreme example, Ford CEO Jim Farley recently threatened to axe the brand’s local engineering program responsible for the best-selling Ford Ranger.“Something your government, or any government, has to be very sensitive to around the CO2 glide path. We want to reduce our CO2 footprint, but there’s a level that the customer can’t afford, and not all duty cycles can be electrified,” Farley told CarsGuide.“It’s a completely open market and also pushing CO2 , arguably way beyond the customer requirements.“ needs to decide if they want to help us equalise the cost differential … because this is among the most expensive places to have engineers on the planet.”We have already seen somewhat of a winding back of Ford’s Ranger line-up Down Under, with the brand discontinuing sale of its bi-turbo diesel engine, in favour of a cleaner single turbo variant.

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.
