Toyota GR Yaris (GXPA16): why a hypercar boss daily-drives one

Toyota GR Yaris: mechanical breakdown

Hypercar boss, GR Yaris, 44 seconds

Indonesian caption: why a hypercar boss picks a GR Yaris for everyday driving. The clip runs 44 s and the caption names no modifications and no events, so there is nothing to tie to a specific part. The car in question is the GXPA16, a 1,280 kg three-door with 257 hp from the G16E-GTS.

Carbon roof, aluminium panels, GR-Four

Unlike the regular Yaris, this three-door body exists only for the GR Yaris. The roof is carbon-fibre-reinforced polymer, and the bonnet, doors and tailgate are aluminium. Those panels are why kerb weight stays at 1,280 kg with all-wheel drive fitted. The GR-Four system sends torque 60:40 front to rear in Normal, 30:70 in Sport and 50:50 in Track. So 360 Nm from the 1,618 cc three is shared with the rear axle by default, and Sport shifts most of it back. Heat soak on track in hot conditions cuts power, which is a limit of the engine, not the shell.

Remap first, then intercooler and exhaust

Most owners start with an ECU remap. On the stock turbo it adds large amounts of power and torque, and the price is higher stress on an engine that already has cylinder 3 failures and high oil consumption on early cars, particularly with track use. A remap can also cause warranty problems. An upgraded intercooler keeps intake temperatures lower and power consistent on track; an oversized core brings more turbo lag. A downpipe and exhaust make it louder and support higher-boost tunes, with emissions and noise legality concerns and drone as the cost.
