2019 Infiniti Q30 Summary

Welcome to the future - where your Mercedes-Benz is a Nissan and your Nissan is a Mercedes-Benz.

Lost already? Let me catch you up. Infiniti is the premium arm of Nissan, in much the same way Lexus is the premium arm of Toyota, and the Q30 is Infiniti’s hatchback.

Thanks to the state of various global manufacturing alliances the Q30 is mechanically, largely a previous-generation Mercedes-Benz A-Class, with a similar arrangement seeing the new Mercedes-Benz X-Class ute comprised largely of Nissan Navara underpinnings.

Recently, the Q30 has had its range of variants trimmed from a confusing five down to two, and the one we’re testing here is the top-spec Sport.

Make sense? I hope so. The Q30 Sport joined me on an 800km trip along the east coast in the height of summer. So, can it make the most of its German/Japanese roots? Read on to find out.

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.

Verdict

The Q30 Sport is a left-field choice in the premium hatch segment. For those who don’t care about badge equity and are looking for something different, the Q30 provides maybe 70 per cent the feel of its well-established competition while offering decent value courtesy of standard safety and spec inclusions.

The biggest letdown is how much better it could be with just a little extra in every department. Even in this top-spec the drive experience is a bit generic, and it’s missing an up-to-date multimedia experience limiting its appeal to a younger audience.

Even with its promising mixed heritage, the Q30 hardly feels more than the sum of its parts.

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).
