Record gradients, loose surfaces, mud depth, snow, water, temperature and recovery access. Occasional gravel does not create the same requirement as repeated remote travel with load.
CAPABILITY / FIELD NOTE 05

Record gradients, loose surfaces, mud depth, snow, water, temperature and recovery access. Occasional gravel does not create the same requirement as repeated remote travel with load.
Check size, load rating, age, pattern, pressure history and matching circumference. Four-wheel-drive control cannot compensate for unsuitable or mismatched tyres, and replacements may be difficult in the destination.
For four-wheel drive, verify rear motor and axle components, underbody protection, cooling, fault history and mode operation. Record impacts or modification work around mounts and wiring.
Consider energy use, tyre replacement, parts availability and workshop capability. The strongest acceleration figure may add little value to an urban family route but still changes maintenance and insurance assumptions.
Confirm towing and recovery procedures for the exact propulsion and driven-axle version. Incorrect lifting or towing can damage electrified driveline components even when the vehicle appears undamaged.
HANDOVER FILE
BUYER SCENARIO
Use a wet paved climb, a loose construction track and an ordinary school route as three separate cases. Four-wheel drive may improve traction in one case while adding little in the others. Compare tyres, load, driver skill and recovery before paying for extra axle hardware, and check whether the destination workshop can diagnose that hardware after an impact or warning.
Stress the result by assuming “Inspect additional hardware” reveals a conflict, “Compare ordinary ownership” is delayed, or “Keep recovery realistic” changes before custody. Rework the cost, timing and stop condition using drivetrain configuration record, underbody inspection, destination recovery plan. A different VIN, propulsion route or installed configuration starts a new candidate record. The conclusion for Tai 7 Two-Wheel Drive vs Four-Wheel Drive must explain how route surface profile and tyre photographs and codes support or limit the selected route.
CLOSE THE FILE
For Tai 7 Two-Wheel Drive vs Four-Wheel Drive, reconcile route surface profile, tyre photographs and codes, drivetrain configuration record, underbody inspection, destination recovery plan. Mark each item verified, seller-stated, estimated or unresolved, and put a responsible person and expiry date beside the open work. Keep commercial rows separate so a change in one assumption does not silently rewrite the whole conclusion.
Immediately before payment or handover, repeat “Classify the difficult surface” and confirm that the candidate still matches the reviewed record. Preserve the VIN, odometer, visible condition, keys, documents and relevant energy state. If the vehicle or a material specification changes, close this file and begin a new one.
