Toyota Vitz TRD Turbo M

While the European Toyota Yaris TS uses a 1.8 liter Dual VVT-i engine producing 130 horsepower at 6,000rpm and 173Nm of torque at 4,400rpm, its Japanese twin with a different name the Toyota Vitz has gone down the forced induction route with the Toyota Vitz TRD Turbo M. Sporting a similiar engine to the Toyota Vios Turbo sold in Thailand some time ago, the 1.5 liter DOHC VVT-i engine 1NZ-FE in the Toyota Vitz gets a bolt-on turbocharger with intercooler and now produces 150 horsepower at 6,000rpm and 195Nm of torque at 4,800rpm, far more powerful than the Yaris TS.

Nearly 200Nm of torque should prove pretty fun for a car that weighs only 1,060kg, but its a shame that peak torque kicks in at such a high RPM, something unseen of with modern turbocharged engines. We’re used to peak torque kicking in under 2,500rpm these days, but then again we have to remember that this wasn’t designed to be a turbocharged engine to begin with, and is a bolt-on. The Toyota Vitz TRD Turbo M rides on a stiffer suspension that also lowers the car by 15mm.

When I was browsing through the Vitz’s microsite, I also found a more powerful normally aspirated variant of the 1NZ-FE that makes 119 PS at 6,000rpm and 147Nm of torque between 4,400rpm and 5,200rpm, compared to the 1NZ-FE in our Toyota Vios which makes the usual 109 PS and 142Nm of torque. We could possibly see this state of tune being made the standard 1NZ-FE tune in the future to counter Honda’s latest series of 1.5 liter engines found in the 2nd generation Fit which already produces 120 PS.
