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.

2020 Audi S7 Summary

If you want something large, fast and comfortable, no one does it better than the Germans, and the latest entrant to the market is Audi’s all-new S7 Sportback.

Using the uber-stylish second-generation A7 as a basis, the new S7 Sportback scores cutting-edge technology and premium appointments befitting a large luxury sedan, but it’s often what’s under the bonnet that will draw buyers in.

This new S7 replaces the old version’s 4.0-litre twin-turbo V8 for a 2.9-litre twin-turbo petrol V6 but, don’t fear, as having fewer cylinders has not dulled its performance or appeal.

As a whole though, does the new Audi S7 Sportback deliver a winning blow?

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

Audi’s S7 Sportback wraps style, comfort and sportiness in an appealing package that is sure to please onlookers and occupants alike.

The great engine/transmission aside, the S7 Sportback also has cutting-edge technology at a more affordable pricetag, though less-than-comfortable rear-seat space lets it down a little.

We wish the car we sampled didn’t have the all-wheel steering, as we much preferred the more neutral feel of the S6 sedan we also drove but, overall, the S7 Sportback puts forward a strong case for its existence.
