What is diesel exhaust fluid (AdBlue), and how does it work?

-
In efforts to keep diesel-fuelled engines on the right side of emissions laws, manufacturers are turning to more and more aggressive means of reducing the kind of bad stuff coming out of the tailpipe. And when things like exhaust gas recirculation and diesel particulate filters aren’t cutting the mustard, something called selective catalytic reduction (SCR) is employed.

2024 Toyota Yaris Cross updated in Europe with new tech, more hybrid power

-
Image
Europe’s Toyota Yaris Cross has received a mid-life update with more power, a revised look and new technology. Plans for the Australian version are yet to be announced. The updated 2024 Toyota Yaris Cross small SUV has been unveiled in Europe with an upgraded hybrid powertrain and new styling.  This is the first update for the Yaris Cross – the SUV sibling to the Toyota Yaris hatch – since it was first introduced to the Australian market in 2020.  Mirroring changes to the European-market Yaris hatch, the 2024 Yaris Cross in Europe brings with it mild styling changes to the exterior and interior of the SUV, improved safety features, and a more powerful hybrid system.  While pre-orders in Europe are due to commence this month, there’s no word on when we can expect to see the updates flow onto the Yaris Cross in Australia.  European-market Yaris Cross vehicles are manufactured in France, whereas Australian-delivered examples are built in Japan.

Ineos Grenadier gets converted into a camper with Australian-made pop-top

-
Image
Mere weeks after hitting the road in Australia, this Ineos Grenadier has already had the roof chopped and converted into a pop-top camper. Ineos Grenadier Pop-top camper The Ineos Grenadier four-wheel drive now has a pop-top conversion available , thanks to Australian company Expedition Centre. Based in Sydney, Expedition Centre has been making pop-top conversions for Land Rover Defenders and Toyota LandCruisers since 2009. But now with the Ineos Grenadier hitting the road in Australia, Expedition Centre has quickly turned its attention to the new, old-school four-wheel-drive wagon. Similar to conversions Expedition Centre has been doing on Defenders and LandCruiser Troopcarriers, the roof of the Grenadier is removed and modified to fit in a slatted 1.3-metre wide Fanello Bed. Hinged at the front and latched at the back, the roof can ‘pop’ open to create additional sleeping and living space inside the vehicle. The roofline of the Grenadier is raised by around 250...

Renault and Nissan production delays due to global cyber attack

-
Image
Renault and Nissan ‘s Sunderland production facility has been the victim of a global cyber attack, causing costly production delays. The global cyber attack began late last week and has so far affected more than 75,000 systems in 100 countries. The attack hits vulnerable Microsoft Windows machines and encrypts the user’s filesystem, taking it ransom. The user is asked to pay a fee of US$300 to have their computer unlocked. While the attack can easily be prevented by updating the operating system, many automated machines and dumb terminals connected to the internet are being infiltrated. A Renault spokesperson told  Autocar, “Groupe Renault confirms it was impacted by the global cyber attack that began late on Friday May 12. It consists of a Ransomware virus. Proactive measures were taken immediately in order to stop the spread of the Virus and protect the group,” the spokesperson said. “A full diagnosis is in progress in order to put in place the appropriat...

2024 Toyota LandCruiser 70 Series facelift spy photo

-
Image
A blurry image found online appears to show an updated Toyota LandCruiser 70 Series. Is Australia’s oldest ‘new’ car about to get another facelift – or is this a retro-inspired model for Japan? A Toyota LandCruiser 70 Series has been photographed in Japan with what appears to be its first makeover in more than 15 years – and it could be in showrooms by the end of this year. The blurry image – which appears to have been taken from a security camera, and shared by @oriba_lc300 and Kurdistan Automotive Blog on Instagram – shows a LandCruiser 76 Series wagon in Japan with a camouflage wrap over the front fascia and a new wheel design. Details are difficult to make out, but the grille appears to wear ‘ TOYOTA ‘ heritage script – similar to the 70th Anniversary special edition unveiled two years ago – and the headlights look to be different from the model in showrooms today. For now it is unclear if this new front-end styling will come to Australia – or if it will be a Japan ex...

The next generation of Hyundai’s smallest SUV in Australia may be two years away, as the South Korean automaker commits to compact, budget-priced cars – even if only as an SUV.

It has been a relative sales success in Australia – whe...

Chevrolet Bolt: One of the cheapest electric cars in the US to return, a slim chance for Australia

-
Image
The Chevrolet Bolt electric hatch – axed earlier this year to make way for production of three-tonne electric pick-ups – is poised to make a comeback, and it could be sold in Australia. The electric Chevrolet Bolt hatchback – axed in its previous form earlier this year so its production line could be used for giant electric pick-ups – is due to return to US showrooms in 2025 with new battery technology .

-
Image
Alfa Romeo has rebooted the iconic 33 Stradale of the 1960s with a limited-edition, custom-built, multimillion-dollar supercar available with twin-turbo V6 petrol, or full battery power. The Alfa Romeo 33 Stradale name has been revived for a new supercar, unveiled in Europe overnight ahead of first customer deliveries overseas due late next year.
