Lexus RC F vs BMW M5

What's the difference?

Ford’s growling Mustang GT isn’t the only rear-wheel drive performance coupe powered by a naturally-aspirated 5.0-litre V8 engine on the Australian new car market.

Pfft! Those things are everywhere. If you’re willing to literally double-down and spend twice the pony car’s circa $65K asking price, the Lexus RC F comes into range; the Japanese luxury brand’s take on a two-door, four-seat, muscle car.

Rather than wrestling with the blue oval, it’s a challenger to the German ‘Big Three’, pitching its deep-breathing, high-revving atmo power against shove-in-back, low-down, turbo-torque.  

We spent a week behind the wheel to see how this mature, but recently updated machine, measures up in 2020.

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?
