For example pretty much every engine now in Toyota's car & truck engines, with the exception of the Yaris (which still has a 1.5 L with Single VVT-i), has Dual VVT-i and a few other goodies to make them more efficient, powerful, durable (in theory anyways), etc. For the 1.5 G, it gets the 1NR-FE mill with an output of 108 PS and 140 Nm of torque. If you're curious, it gains 1 PS and loses 2 Nm of peak torque when compared to the old NZ-series unit. While New 2016 Toyota Vios launched in Malaysia - EEV, Dual VVT-i, CVT, VSC standard, RM76,500 - RM96,400. Posted in Cars, Local Car Launches, Local News, Toyota / By Danny Tan / October 4 2016 10:46 am Furthermore, VVT also broadens the torque curve before the peak, and prevents horsepower from dropping off rapidly after the horsepower peak. "With variable valve timing, we typically see a 5-10 Wrong.". "The stock 1JZ bottom end is good for 650-700, which is 260 - 280 hp/liter (650hp/2.5liter=260hp/liter). The stock 2JZ bottom end in good for around 800, which is 266hp/liter.". "Both of these engine's bottom ends have been pushed way past the numbers I've just quoted. The peak torque rating for the dual VVTi engine is slightly less than the single VVTi engine, and the torque peak occurs at 600 RPM higher, but the torque curve is much flatter, and there is slightly more usable torque at lower-to-midrange revs. oVcg.
