2020 Audi S6 Summary

Most buyers don’t care for sedans these days, but those in the premium market are still spoilt for choice, with new model after new model being launched.

The latest on offer is the new Audi S6, which once again attempts to mix executive style with boy-racer performance.

With its predecessor’s 4.0-litre twin-turbo V8 succeeded by an engine that is 1.1 litres and two cylinders short, does it still serve up enough bang for your back?

Of course, the only way to find out is to put the new S6 sedan to test, so that’s exactly what we did. Read on.

2025 Mercedes-Benz E-Class Summary

You like performance, love a bit of luxury and fancy a traditional sedan. The budget is healthy and there’s a surprising amount of choice. But Mercedes-AMG believes it’s created the car that perfectly answers your new-car brief.

The Mercedes-AMG E53 Hybrid 4Matic+ is a fresh expression of an established high-performance sedan formula mixing internal-combustion power with electric punch and all-wheel drive.

We were invited to its local launch, so stay with us to see if this newcomer is ready to fill that primo European performance car shaped space in your garage.

Verdict

We adore the new S6 sedan. It looks great, feels comfortable and goes like stink all at the same time. What’s not to like?

It also helps that it is relatively good value, safe and practical by large-sedan standards, so it’s a bit of a no-brainer.

But will buyers be quick to dismiss the new S6 sedan because it’s not a more practical SUV? Time will tell, but we hope not.

Does the new Audi S6 sedan represent the best mix of executive style and boy-racer performance? Tell us what you think in the comments below.

Verdict

The Mercedes-AMG E53 Hybrid 4Matic+ is a superb blend of high-tech hybrid muscle and cossetting top-end luxury. Value is competitive, it looks (and feels) the business, despite the conventional sedan configuration it’s surprisingly practical (except for the modest boot), fuel-efficiency is a key benefit and safety is stellar. The ownership proposition is okay for the category but that’s not top of mind when an enticing series of corners ranges into view. It’s an impressive package.
