The GR Yaris’s engine is an all-new, three-cylinder turbocharged unit that benefits from motorsport technologies to maximise performance, including multi-oil jet piston cooling, large-diameter exhaust valves and a part-machined intake port. Displacing 1,618cc, it produces a maximum 257bhp/192kW and 360Nm of torque.
Compact and lightweight, the DOHC 12-valve engine features a single-scroll ball-bearing turbo and is matched to a six-speed manual transmission, engineered to accommodate high torque levels.
Achieving a strong power-to-weight ratio was a key objective to help meet the GR Yaris’s performance targets. The body shell is constructed predominantly from lightweight materials, including a new carbon fibre polymer for the roof that can be compression moulded. Aluminium is used for the bonnet, doors and tailgate. As a result, the GR Yaris has the power of a C-segment performance hatch but the weight of a B-segment machine (kerb weight 1,280kg). Its power-to-weight ratio of only 5.0 kg per bhp helps deliver 0-62mph acceleration in less than 5.5 seconds and an electronically limited top speed of 143mph.
The GR Yaris’s performance is supported by a new GR-Four all-wheel drive system designed to optimise drive power to each wheel, while also being simple and lightweight. The distribution of torque between the front and rear axles is governed by a high-response coupling. As an option in the Circuit Pack (details below), two Torsen limited-slip differentials manage the split between the left and right-side wheels to give natural and direct car control.
The ingenious system uses slightly different gear ratios for the front and rear axles and allows for a theoretical range of front/rear torque balance from 100:0 (full front-wheel drive) to 0:100 (full rear-wheel drive). This flexibility gives a performance advantage over AWD on-demand systems that use twin-coupling or permanent AWD systems with a centre differential. The GR Four system is also considerably lighter in weight.
The driver can adjust four-wheel drive performance to suit their preference or the driving situation using a 4WD mode dial switch. In normal mode the base front/rear torque distribution is 60:40; in Sport mode the balance shifts to the rear, with 30:70 distribution to achieve a fun-to-drive quality on winding roads and circuits; and in Track mode the base setting is 50:50 for fast, competitive driving on circuits or special stages. In each mode, the torque balance will automatically adjust in response to the driver’s inputs, vehicle behaviour and road or track conditions.
The GR Yaris has a new, dedicated platform that combines the front end of Toyota’s GA-B platform – debuting in the all new Yaris model in 2020 – with the rear of the GA-C platform. This allows for a new suspension design and accommodation of the GR-Four all-wheel drive system, while also contributing to the car’s excellent stability and handling.
Where the standard new Yaris uses a torsion beam rear suspension, the GR Yaris has a double wishbone set-up, with every element optimised for performance. A MacPherson strut system is used at the front.
