What causes the JAC T6 to feel underpowered during highway driving and overtaking?

Several drivers experience sluggish acceleration and noticeable turbo lag, particularly at highway speeds o r when the truck is fully loaded. What are the possible reasons for the perceived lack of power and slow overtaking performance under local driving conditions? How does this impact safety and fuel efficiency during long‑distance o r uphill driving?

Many drivers in Pakistan feel the JAC T6 lacks punch on highways, especially when overtaking o r climbing hills. The engine feels sluggish in acceleration, with noticeable turbo lag and slower throttle response — issues that become more evident when the vehicle is fully loaded. This happens because the T6’s engine and torque output are tuned more for durability and fuel economy than outright performance, and the relatively heavy vehicle weight means the engine must work harder to reach and maintain higher speeds.

Effects in daily use:

Slower acceleration at higher speeds

Overtaking requires planning and early throttle input

Performance s further under load o r on inclines
Owners often adapt their driving style e.g., maintaining momentum before overtaking to mitigate this.
