Toyota GR Yaris (GXPA16) at a Sri Lanka meet: GR-Four splits

Toyota GR Yaris: mechanical breakdown

A GR Yaris at a Sri Lankan meet

Per the title, a GR Yaris parked at a car meet in Sri Lanka. The caption only calls it the famed GR Yaris. It names no modifications and no event, so there is nothing further to tie to the hardware.

GR-Four torque splits by drive mode

GR-Four gives the driver three front-to-rear torque splits, and the G16E-GTS puts 360 Nm through whichever is selected. Normal is 60:40. Sport is 30:70, which moves most of the torque to the rear axle. Track is 50:50, an even division between the two. Because the split is a selectable setting, the same 1280 kg car delivers its 257 hp differently depending on the mode chosen. Owners who switch modes are changing how engine output is divided between axles, not the engine itself.

Why owners remap and open up the exhaust

Most owners start with an ECU remap. It adds large power and torque on the stock turbo, and the price is higher engine stress and possible warranty problems. That weighs more on a car where early examples have reports of cylinder 3 failures and high oil consumption, especially with track use. A downpipe and exhaust make it louder and support higher-boost tunes, with drone and emissions and noise legality as the cost. Track drivers fit an upgraded intercooler against heat soak, which cuts power in hot conditions. Cost aside, an oversized core brings more turbo lag.
