The Mazda 6 is up to $1000 more expensive for 2023, but has received various specification updates plus a new special edition.

    It’s also the latest model from the brand to adopt Mazda’s new powertrain naming conventions.

    The naturally aspirated 2.5-litre four-cylinder Sport and Touring are now the G25 Sport and G25 Touring, while the turbocharged 2.5-litre GT SP and Atenza are now the G35 GT SP and G35 Atenza.

    G25 Sport models get the smallest price increase – $300 – as they’re the recipient of the fewest upgrades.

    All 2023 Mazda 6 models get an updated power steering system, while G25 Touring and up now get wireless Apple CarPlay for their otherwise carryover 8.0-inch MZD Connect touchscreen infotainment systems.

    G35 GT SP and G35 Atenza models get the brand’s Cruising and Traffic Support semi-autonomous driver assist feature.

    The G35 GT SP also gets “black gloss signature wings front and rear” with the wagon also getting gloss black roof rails, while G35 Atenza models come standard with black Nappa leather upholstery – sadly, the Walnut Brown and Pure White colourways are no more.

    The flagship Skyactiv-G 2.5-litre turbocharged petrol engine now develops 173kW (up 3kW) at 4250rpm. Peak torque remains at 420Nm (at 2000rpm), but Mazda says the motor will make an additional 8Nm at 4250rpm compared to before.

    Mazda says the six-speed automatic has also been updated to “provide a more direct upshift response and exciting driving feel”; while the “reactive force of the accelerator pedal has been increased to provide more direct and intuitive connection to the engine’s torque”.

    The special 20th Anniversary edition, commemorating two decades and more than 144,000 Mazda 6 sales in Australia, is based on the G35 Atenza and comes exclusively in Artisan Red and Rhodium White metallic finishes.

    Other distinguishing exterior features include 20th Anniversary badging and high-gloss silver 19-inch alloy wheels.

    Inside, the Mazda 6 20th Anniversary special uniquely offers a tan interior trimmed in Leganu suede and Nappa leather. The front headrests are also embossed with 20th Anniversary logos.

    While the Mazda 6 has now been discontinued in the United States, Canada and the United Kingdom, Mazda Australia says it remains an “important model” here. It’s unclear just how much longer it will be around, however, given it’s now over a decade old with no replacement in sight.

    Despite its age, Mazda sold 1511 6s in 2022, making it the second best-seller in its segment, albeit well behind the Toyota Camry (9538 sales).
