VGT Turbocharger: Power Exactly When You Need It
Story by Ezad Alfuso
The Problem With Normal Turbos
A standard turbo only works “best” at high RPM.
At low RPM, you get weak boost… and that familiar delay called turbo lag.
What happens:
🔥 Low RPM → exhaust flow is weak → turbo spins slow → power feels delayed
🔥 High RPM → exhaust flow strong → turbo kicks in → power finally comes
The issue is simple:
A fixed turbo forces you to choose — strong low-end OR strong high-end.
You rarely get both.
How VGT Changes Everything
FUSO uses a Variable Geometry Turbocharger (VGT) in the 4P10 engine.
It’s a turbo with movable vanes inside the turbine housing.
These vanes automatically change their angle depending on engine speed.
The result?
🔥 Strong boost at low RPM
🔥 Stable boost at high RPM
🔥 Power at every speed
🔥 Zero turbo lag
It transforms your driving experience immediately.
How VGT Works
At Low RPM — Starting From Standstill
The vanes tighten.
🔥 Exhaust gas path becomes narrow
🔥 Gas speeds up
🔥 Turbo spins faster even with low flow
🔥 Boost comes instantly
What you feel:
🚀 Powerful pickup from traffic lights
🚀 Easy merging into traffic
🚀 No more slow “dead spot” when starting
At High RPM — Highway Cruising
The vanes open wider.
🔥 More room for exhaust flow
🔥 Prevents overboost
🔥 Maintains stable pressure
🔥 Delivers smooth, consistent power
What you feel:
🛣️ Confident overtaking
🛣️ Smooth highway acceleration
🛣️ Stable performance even with load
Real-World Benefits

VGT vs Traditional Turbo
Traditional Turbo
⚠️ Weak at low RPM
⚠️ Strong only at high RPM
⚠️ Big turbo lag
⚠️ Harder to drive when loaded
VGT Turbo
🔥 Boost at every RPM
🔥 No lag
🔥 Smooth power delivery
🔥 Better response with heavy loads
This is why the 4P10 outperforms older engines with bigger displacement.
How ECU Controls the VGT
Your truck’s ECU adjusts the turbo vanes automatically based on:
⚙️ RPM
⚙️ Throttle position
⚙️ Boost pressure
⚙️ Load (empty vs full)
⚙️ Temperature and altitude
All in milliseconds.
You press the pedal — the ECU handles the rest.
Why It Matters When Loaded
Traditional turbo + full load = slow response.
VGT + full load =
🔥 Strong pickup
🔥 Confident movement from standstill
🔥 Smooth climbing
🔥 No struggling
This is where VGT proves its worth daily — especially for delivery trucks.
The Perfect Combo: VGT + Flat Torque Curve
The 4P10 delivers:
370 Nm from 1,350 rpm to 2,840 rpm
That’s an extremely wide torque band.
So with VGT delivering instant boost…
and 370 Nm available almost immediately…
What you get is effortless driving.
Anywhere. Anytime.
What Customers Usually Tell Me
“Pickup memang best, tak sangka 3.0 boleh tarik macam ni.”
“Full load pun steady dekat traffic light.”
“Highway overtaking dia smooth gila.”

That’s the VGT difference — you don’t see it, but you feel it.
