New piggyback-style ECU tuning options are also being prepared to capitalise on this extra ‘lung’ capacity, with current calibrations and dyno figures suggesting a 300bhp output is achievable without any changes to the powertrain itself. Litchfield’s black GR Yaris hosts the engine upgrades, while the white GR Yaris is equipped with the chassis upgrades, as seen by its 40mm lower ride heightĪ broad range of tuning parts are currently in development, the purpose of which we believe will tighten the focus of the GR Yaris towards becoming either a dedicated rally car or a more hunkered down, tightly controlled road/track car.īreathing modifications are a given in both fields, with Litchfield’s in-house engineers developing high-flow intake, intercooler and exhaust systems. Not one but two brand-new GR Yaris models were purchased, which has allowed the Gloucestershire tuner to test new products back-to-back and make rapid but calculated decisions on everything from the tone of an exhaust to the rebound settings of a damper unit. So in order to try and position the company at the forefront of GR Yaris modifying in the UK, proprietor Iain Litchfield immediately instructed the development of a comprehensive tuning programme. Litchfield is renowned for knowing a thing or two about optimising front-engine, four-wheel-drive vehicles.
In its appraisal of what will be the next big thing in the aftermarket tuning scene, we were delighted to hear UK performance centre Litchfieldmake the following comment: “No performance car in recent memory has hit the ground running as fast as the all-new Toyota GR Yaris,” a hot hatch that is described as rekindling the “unbridled fun of all-paw homologation specials.”
