2025 Audi S3 Summary

In a world where car upgrades often feel like saying, “Can I upsize that?”, it’s refreshing to hop into the updated Audi S3 Sportback.

The flagship RS 3 may still be the holy grail of hot hatch dreams, but with boosted engine outputs and upgraded tech, the S3 is stepping up.

Is the S3 Sportback the smarter pick over pricier rivals? It delivers serious performance and polish without stretching into RS 3 territory. With fierce competition in the segment, let’s see what this contender brings to the table.

2025 Ford Mustang Summary

The new Ford Mustang GT was not designed for Paris.

Fighting through the morning peak hour rush (which seems to extend through the middle of the day and the afternoon), the new Mustang feels like a caged animal. Which is appropriate, given the car’s namesake is a wild horse that exists to roam the American wilderness.

But once we finally break the shackles of Parasian traffic we find ourselves getting to let this Mustang gallop across the French countryside and unleash its full potential. But more on that later…

The reason we're driving the Mustang in France is because the American brand wanted to connect it to its new racing program at the famous Le Mans sports car race (you know, the one in the Matt Damon movie, Ford v Ferrari).

No less than Bill Ford, great-grandson of the company’s famous founder, was on-hand to see the Mustang at Le Mans, such is the passion for performance.

Ford (the man, not the company) took the opportunity to declare that the Blue Oval brand is not only committed to internal combustion engines for the foreseeable future, but it will retain the V8 under the bonnet of the Mustang GT for as long as it can legally do so.

Australians will have to wait a few more weeks (maybe months) before the seventh-generation Mustang arrives, but here’s what you can expect when it lands on local roads.

Verdict

The updated Audi S3 Sportback is a fun-sized dynamo with impressive outputs and athletic road manners. It’s missing a few premium features, but its compact size paired with a gutsy engine makes it a compelling option for drivers who don’t want to compromise on performance (just space).

Verdict

Having driven the latest example of the Mustang GT, I hope Bill Ford is true to his word and keeps the V8-powered Mustang for as long as possible. It isn’t the most razor-sharp sports car or the most powerful muscle car, but it offers the kind of driving thrills and enjoyment that have made the car an icon.

The price increase is steep but the new technology inside drags the Mustang into the modern era and will add more youth appeal to a car that is largely unchanged in concept for the past 60 years.

But now that I’ve driven it in the USA and France, I can’t wait for it to finally reach Australia.
