"Some homologation specials relate very loosely to their racing cousins, but the GR Yaris is a proper job. The three-door shell and bodywork are bespoke. The roof is lowered by 91mm and made of carbon fibre, and the doors are frameless.

Underneath, it’s a merging of the Yaris chassis at the front, and the Corolla at the rear. This allows for clever double-wishbone suspension and that 4WD system. It even has a manual gearbox.

While the regular white-goods Yaris is built in France, the GR will be made at a specialised Gazoo Racing facility in Motomachi, Japan, using ‘a large number of manual processes’. As well as Gazoo Racing, the GR Yaris also had input from the WRC Tommi Makinen Racing team."

You can see from this how unique the GR Yaris is and totally different in every way from a standard (homologated) Yaris.

It is in essence a Yaris in name only - hence the requirement to make 25,000 units to homologate this new 2021 car.
