A fresh report claims the new, limited-run BMW M5 CS will debut later in 2020, complete with lightweight parts and as much as 478 kW from its twin-turbo 4,4-litre V8.

According to BMWBlog, the new M5 CS will “follow the recipe” of previous models wearing this badge, such as the M3 CS and M4 CS. That suggests minor styling changes up front, some special exterior paint colours and model-specific alloy wheels.

The cabin, meanwhile, will likely gain a smattering of “M5 CS” badges and some special trim, while a carbon-fibre rear spoiler is apparently on the cards, too. Meanwhile, uprated brakes look set to be offered as an option.

And peak power? Well, while the eight-cylinder in the recently refreshed M5 Competition pumps out 460 kW and 750 N.m, the report claims the CS-badged flagship will generate around 478 kW and up to 800 N.m, again sent to all four corners via an eight-speed automatic transmission.

In addition, the M5 CS is expected to benefit from software tweaks to render it a little more tail-happy in rear-wheel-drive mode…
