Understand official Tank 300 fuel figures, tank capacity and real-world range variables for petrol, HEV, diesel and plug-in hybrid versions.
Read official figures in their market context
Record the source country, test procedure, grade and publication date beside every number. A figure from a current South African brochure is evidence for the versions described there, not proof that a Chinese petrol, Hi4-T or special edition has the same calibration, mass or certification. Do not mix WLTC, NEDC and other cycles in one ranking without labels. For a used vehicle, check tyre size, roof equipment, suspension and stored diagnostic faults because these can make even the correct catalogue figure a weak predictor of present operation.
Calculate range conservatively
A simple planning estimate divides usable fuel by expected consumption, but the full nominal tank should not be treated as routine usable range. Keep a reserve for route changes, gradients, wind, soft surfaces and fuel-station uncertainty. For example, an 80-litre tank and a 9.5 L/100 km official figure imply a theoretical result above 800 km, yet an owner should not publish that arithmetic as guaranteed range. Build normal, adverse and remote-route cases using measured consumption from the actual vehicle after arrival.
Load and terrain change the answer
A roof tent, recovery equipment, passengers, larger all-terrain tyres and a trailer add aerodynamic drag, rolling resistance and mass. Low-range work, sand, mud, steep climbs, idling and repeated recovery can consume fuel without covering much distance. Cold weather, high altitude and short trips can also move the result. Ask the seller for an unedited trip-computer view only as supporting evidence; calculate the operating budget from the owner’s route and validate it over several full-tank records.
PHEV range needs two ledgers
For a Hi4-T or another plug-in configuration, separate electricity use, charged distance and fuel use. Confirm usable battery information, charging losses, inlet, voltage, cable, climate demand and whether the owner can charge where the vehicle is parked. A quoted electric range is a test-cycle result, not a promise for highway driving, towing or low-temperature use. Long trips also need a depleted-battery fuel scenario so the buyer understands operation after the initial charge is consumed.
Evidence to collect
- Market and test cycle
- Exact fuel or electrified version
- Tank and battery specification
- Tyres, accessories and payload
- Normal and adverse range cases
- Measured post-arrival consumption log
Apply the guide to a real candidate
Keep a repeatable consumption log
After arrival, record odometer, litres added, price, route mix, tyre pressure, payload and dashboard result at every fill. For PHEV, record wall energy as well as fuel. Several full cycles reveal a useful seasonal baseline and can flag a change caused by tyres, alignment, brakes or a developing fault. Do not compare one downhill trip with a lifetime average. A log is also more persuasive for maintenance and later resale than a recollection that the vehicle “usually” achieved a particular number.
Plan remote fuel by consequence
Mark reliable fuel points, operating hours, payment restrictions and the longest diversion. Apply the adverse consumption case and retain a reserve that fits the route’s consequence, not an arbitrary percentage copied from urban use. Any auxiliary fuel system must be legal, securely installed and isolated from passengers and heat sources. Carrying extra fuel adds mass and changes load distribution, so it belongs in the same payload calculation as water, tools, passengers and recovery equipment.
Final approval control
Approve the operating budget with three consumption cases and a documented reserve policy. Keep official figures labelled as test-cycle references, then add measured evidence from the candidate only when the conditions are known. For a plug-in vehicle, show fuel and electricity separately and include a no-charge scenario. The resulting plan should state the longest intended leg, available refuelling or charging points, payload and seasonal conditions. Range is a route-management control, not a marketing maximum, and it should be revised after the owner has collected repeatable local data.

Specifications and equipment can vary by market, model year, trim, VIN and production batch. Verify the exact vehicle and current destination rules before purchase.

How far can a Tank 300 travel on one tank?
Calculate it for the exact version and keep a reserve; terrain, speed, load, tyres and weather can materially reduce theoretical range.
Does the HEV always use less fuel than petrol?
Official figures can favour HEV in a listed test, but the real difference depends on route, temperature, load and driving pattern.
Can I combine electric and fuel range for Hi4-T?
Only as a labelled scenario. Charging, temperature and use determine electric contribution, so do not present the sum as guaranteed range.
