That's why we've always emphasised here that the D-max 3.0, kahit naka-VGT pa yan, is not meant to be a dragster like the others since the engine is configured as a LONG-STROKE diesel - small bore with long stroke.... All the others can rev faster in a given time because they have relatively shorter strokes. Que Ranger 3.0 TDCi pa yan o Hilux 3.0 D-4D, if you look closely sa specs nila, they have less stroke lengths than the D-max. The D-max 3.0 Ddi-iTEQ and the iTEQ VGS Turbo all have almost much of the same stroke length as the Strada 3.2 Di-D engine's stroke, i.e. 104.9mm vs 105.00mm, only that the bigger Strada has the bigger bore diameter.
Pang-akyatan magaganda at kargahan ang mga longer stroke diesel engines sir, which incidentally is also how haul trucks, tractors are also configured for higher and broader torque to reach even at low revs or rpm-range. Mabilis pa nga umarangkada Innova 2.5 D-4D namin kaysa sa dalawang D-max, namely, 3.0 TD Intercooler (Pinas-model) at 3.0 Ddi-iTEQ namin.
By the way chief, nagda-drive din ako ng D-max 3.0 iTEQ VGS Turbo sa Spain (nung andun pa ako na-assign at ang emblem nito sa Europe ay 3.0 TD Intercooler) at sa Australia (ganun din same emblem 3.0 TD Intercooler).... This is the hood-scoop D-max that we all know of anyway, at ganon din acceleration nila, mabagal din kahit naka VGT pa sila kasi long-stroke diesel din design. It takes more time for them along the cylinder to travel from top dead centre (TDC) to bottom dead centre (BDC) to complete a stroke relatively than those short-stroke ones and those "not so much" a long-stroke ones ;)
Magaganda gumapang mga D-max hindi lang sa patag chief, kahit pa sa akayatan. "Gapang" in English is what is known as "LUGGING", where you think the engine will shut down due to its low revs but it can still sustain going through the ascent due to its "rolling" power, even when, say, the dirt road is slippery, that's why the D-max engine is ever described by the Australian 4x4 pickup experts as "LESS STRESS" engine pickup among the bunch ;)
