About the GR Yaris
The Toyota GR Yaris is a rally-bred, three-door hot hatch developed by Toyota Gazoo Racing. It packs a bespoke 1.6L turbocharged three-cylinder (G16E-GTS) — the most power-dense three-cylinder engine ever fitted to a production car — driving all four wheels through the GR-FOUR system with a Torsen front and rear LSD option.
This example is a late 2022 Gen 1 car, purchased at 100 miles, and has been transformed into a genuine motorsport build — engineered for the track, fully road-legal, and a proper B-road killer. Fully built engine, Xshift 7-speed sequential, MME paddle shift, full Verkline chassis, AP Racing brakes, Protlum coilovers, and a full Syvecs E85 calibration.
Performance
Fully calibrated by Syvecs with two distinct maps switchable on the fly — pump 98 for road use and a stronger E75/E85 ethanol tune for maximum attack.

Condition
Freshly serviced, fresh gearbox, fresh transfer case, minimal miles on the suspension and brakes. The car is in drive-away condition with plenty of consumables still to run.
Never rallied — track and road use only.
Setup
Geometry and chassis setup by String Theory Garage — UK-based Toyota GR specialists. Three dedicated sessions: initial fitment, on-car tweaks, and final road & track alignment.

Every link, arm and subframe under this car has been replaced. The complete Verkline WAS-605 motorsport suspension kit is fitted, finished in a custom acid-green powder coat. A full uniball design eliminates rubber-bushing deflection and transforms the geometry — FEM-validated across seven motorsport load cases, and 17 kg lighter than stock.
