GWM’s flat-eight engine could power cars – report
As the rest of the automotive industry has been phasing out eight-cylinder engines, China’s GWM has been doing the opposite.
Now, it is considering utilising its unusual horizontally opposed eight-cylinder engine in its cars.
GWM originally unveiled a 2.0-litre flat-eight engine at the 2024 Beijing motor show in 2024, and followed it up with a 4.0-litre twin-turbo V8 the following year.

But while the V8 was created to be used in its range of off-road vehicles – potentially the Tank 300,500, and 700 – the flat-eight ‘boxer’ engine was originally designed for the company’s Souo S2000 touring motorcycle.
“We can put this [eight-cylinder] engine in other vehicles in the future,” a spokesperson for GWM told US publication Car and Driver.
“This is not just for motorcycles… it’s for cars.”

In contrast to the ‘boxer’ engines produced by Subaru – where the cylinders look like a boxer punching gloves together – the GWM engine is more similar to flat-six engines made by Porsche, in which one litre of gas moves as the other moves outwards.
The cylinders are 180-degree, so that it is more closely related to a V8 engine (not the 90- degree ‘V’ shape) than its traditional counterpart.
