What specialist means

More useful torque.
Not a bigger number at any cost.

TOW

Controlled load response

Calibration shaped for predictable torque, temperature management and the way a towing vehicle actually accelerates.

WORK

Driveability through the day

Useful response and clean delivery for pickups and utility vehicles carrying weight or covering difficult ground.

TOUR

Confidence over distance

Smoother overtaking, flexible mid-range torque and an assessment that respects reliability and service history.

TRAIL

Low-speed control

Progressive throttle response matters when grip and vehicle placement count more than a headline power figure.
