Toyota GR Yaris (GXPA16) Rally2 ride-along with Yağız Avcı

Toyota GR Yaris: mechanical breakdown

Rally2 GR Yaris ride-along at a track

Yağız Avcı drives and the uploader rides along in a GR Yaris Rally2, in a 40-second clip with the event given as a track. The Rally2 car is built from the GXPA16 road car, whose G16E-GTS is a 1,618 cc turbocharged three-cylinder. The caption names no parts, so nothing further is stated.

How iMT rev-matching works on the 6-speed

Rev-matching on the GR Yaris is handled by iMT, an electronic function on the 6-speed manual that can be switched on or off. On a downshift the system raises engine speed to match the lower gear, so the clutch comes up without the driveline jolt that would otherwise unsettle an AWD car on the way into a corner. With it off, the driver does the heel-and-toe work. Torque is 360 Nm from 1,618 cc, and that load passes through the same clutch and gearbox either way. Switching it off is a choice about who controls revs, not a change to the hardware behind it.

Remap first, then intercooler and downpipe

An ECU remap comes first. On the stock turbo it adds large gains in power and torque, and the price is higher engine stress and possible warranty problems. An upgraded intercooler follows, since it lowers intake temperatures and keeps power consistent on track; an oversized core adds turbo lag. A downpipe and exhaust make the G16E-GTS louder, with more turbo and wastegate noise, and they support higher-boost tunes. Drone on the highway and emissions and noise rules are what owners give up. Each step leans harder on the one before it.
