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?

2025 BMW M5 Summary

Balancing luxury car comfort, hot hatch agility and supercar speed is no easy task, yet that is what made the six previous generations of BMW's M5 so iconic. 

In seventh-generation ‘G90’ guise, the M5 has another skeleton in the cupboard: the toughest emissions regulations that Europe, and now Australia, have ever seen.

A twin-turbo V8 was untenable and going battery electric was not an option. Plug-in hybrid was the only answer. For the new M5, BMW combined a revised 4.4-litre ‘S68’ bent eight with a punchy electric motor for 535kW and 1000Nm

Problem is, the G90 is widely acknowledged as one of the greatest BMW M cars of all time, especially in CS trim. And thanks to a circa-600kg weight hike to nearly 2500kg, the new M5's 0-100km/h claim is actually slower than the old 'F90' M5. 

Doesn’t exactly sound like a big leap forward, does it?

A drive through the Central West of NSW and around the iconic Mount Panorama racing circuit gave us answers to two questions. Does the M5 work on Australia roads, and does BMW M's latest super-sedan represent progress?
