Subaru WRX vs BMW M5

What's the difference?

The Subaru WRX – do we even need to introduce this iconic beastie at all? With its rally winning roots to being a legend in its own suburb, the ‘Rex’ is a sports car that’s affordable and fun – although the one we’re testing here is one of the pricier versions: the WRX tS Spec B.  

So what is a tS Spec B? Well, the old king of the WRX world – the STI – was retired at the end of the previous generation. Now this new grade – the tS Spec B – is the new WRX monarch. 

So does this mean the tS Spec B has more superpower than the rest of the line-up? Does it have a bigger engine? How much more does it cost? Does it have a manual gearbox? So many questions – the answers are below.

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?
