BYD Shark 6 towing capacity: 1,000 kg more tow leaves 165 kg less to carry

The change list BYD published, and the two parts missing from it

The Shark 6 reached Australian customers in February 2025 rated to tow 2,500 kg braked. In March, as CarExpert reported, BYD emailed its owners asking whether they wanted a factory-backed upgrade to payload and towing. The answer shipped in May 2026 as a third variant, and its change list is short enough to read in one sitting: a 180 kW 2.0-litre in place of the 135 kW 1.5-litre, a front motor lifted from 170 kW to 200 kW, larger front brake discs and revalved dampers. Those changes arrived with a combined ceiling of 6,650 kg against 5,750 kg, a 350 kg tow-ball maximum against 250 kg, and a 3,500 kg braked rating against 2,500 kg.

The current primary records establish the result, not which component earned it. The wheelbase remains 3,260 mm, GVM 3,500 kg, battery 29.6 kWh and tank 60 litres. The Performance's rear axle maximum is 1,900 kg against 1,927 kg on the 1.5-litre variants, even though its ball maximum is 100 kg higher. Published sources do not establish that the frame was unchanged or that any one powertrain change unlocked the extra tonne.

Both engines remain in the range, and the Dynamic Cab Chassis joined them on a 2,600 kg kerb before a tray. The 2.0T PHEV row is Performance and the 1.5T PHEV row is BYD Shark 6 Premium. Read the compliance plate and ROVER variant identifier rather than inferring limits from a model-year label.

What the 70-to-90 kW generator change tells us — and what it cannot prove

A plug-in hybrid carries power sources with different endurance. BYD markets 321 kW for the 1.5-litre and 350 kW for Performance; the current ROVER variant record instead lists 345 kW combined for Performance, a published discrepancy that owners should not turn into a sum of its three individual machine ratings. Engine-driven generator feed is separate. Chasing Cars reported 70 kW from the 1.5-litre and 90 kW from the 2.0-litre, describing lower throughput as one constraint under sustained load.

Chasing Cars also described the motors drawing from the 29.6 kWh pack faster than the 1.5-litre could replenish it on a long, steep incline with a heavy van. As state of charge falls, sustained performance depends increasingly on engine-driven generation and the reserve the hybrid control system maintains; it is not correct to reduce the whole system to the engine's 135 kW nameplate. The 20 kW generator difference is therefore relevant evidence, not proof that it alone produced the 1,000 kg rating change. BYD changed the engine, front motor, brakes and damping together.

The brakes belong to the same story. CarsGuide noted in April 2025 that the hybrid system produces very little engine braking even at maximum regeneration, so a long descent leans on the friction brakes in a way a diesel holding a low gear does not — and larger front discs came with the higher rating. Going up, the habit owners share is to hold a higher state of charge before a known climb, commonly 50 to 75 per cent — community practice, not a BYD instruction. Nobody has published the run that would settle it: no dated Australian test has taken a Shark 6 up a real hill on a depleted battery with a heavy van behind.

BYD Shark 6 GVM, GCM and payload: two ceilings that run out together

Run the usual check on a Shark 6 and it comes back a dead heat. Add a 1.5-litre variant's 3,500 kg GVM to its 2,500 kg braked rating and you get 6,000 kg against a certified combined ceiling of 5,750 kg, a shortfall of 250 kg. On a Performance, 7,000 kg meets 6,650 kg, a shortfall of 350 kg. Those two shortfalls are the two tow-ball ratings, to the kilogram, on all three variants: BYD has written each variant's combined ceiling as GVM plus braked tow minus the tow-ball download, which across two rating levels reads as a rule and not an accident.

The consequence is a tie. On BYD Shark 6 Premium, 3,500 kg GVM less 250 kg ball and 5,750 kg GCM less 2,500 kg trailer both equal 3,250 kg. Performance returns 3,150 kg either way. Subtract kerb weight: 540 kg remains on Shark 6 Premium, 375 kg on Performance and 650 kg on Dynamic Cab Chassis before a tray. At full GVM, Shark 6 Premium may hitch 2,250 kg and Performance 3,150 kg. The gross combination mass guide explains why ball mass is deducted once.

Fuel consumption and range with a caravan on the back

Three dated reports land in a similar band. carsales recorded 17.4 L/100 km behind 2,400 kg in May 2025. RACV published 18 L/100 km at the full 3,500 kg on 28 May 2026, but called its run a controlled proving-ground exercise needing a public-road test. A Performance owner reported 186 litres over 1,087 km towing a 2.2-tonne camper from Perth toward Coral Bay in July 2026 — 17.1 L/100 km by the recorded totals — with 33-inch tyres and about 250 kg in the tub, so it is useful experience rather than a controlled comparison.

The Shark 6 carries 60 litres of fuel, and that is where a towing question turns into a route question. At 17.4 L/100 km a full tank is about 344 km dry, and carsales put the usable figure at roughly 294 km once you keep 50 km in hand. At 18 L/100 km it is nearer 330 km. Unladen, two Australian owners posting in May and June 2026 reported 9 to 11 L/100 km once the battery is done, against BYD's published 7.9 and 10.5 L/100 km below 25 per cent state of charge. The cited 17.4–18 L/100 km towing results were roughly 1.6–2.0 times those owner-reported unladen figures; they do not predict every van or route.

In the carsales test the ute used its engine to maintain a battery reserve. The July 2026 owner found the engine worked harder near 50 per cent charge and planned fuel stops every 200 to 220 km. Those are trip observations, not a BYD rule. Official unladen electric range is 100 km on Shark 6 Premium and 80 km on Performance.

Tow-ball load and the rear axle rating that went down

The 1.5-litre variants have a 1,927 kg rear-axle maximum and a 250 kg ball maximum; Performance has 1,900 kg and 350 kg. That makes the axle check more important on the grade rated to tow more. BYD publishes neither per-axle kerb distribution nor the ball-to-axle dimension, so no responsible remaining-margin or hitch-load-transfer figure can be calculated from public data. Get an axle-by-axle weighbridge ticket with the rig loaded.

Every Shark 6 uses a coil-sprung double-wishbone rear end. In its May 2025 test, carsales measured 20 mm of rear drop and 5 mm of front rise with about 200 kg on the ball and reported no sway at 100 km/h. That is evidence for that 2,400 kg test combination, not a promise for a 3,500 kg caravan.

What 375 kg has to cover on a Performance

CarsGuide loaded 650 kg into the tub plus a driver in April 2025, about 750 kg against BYD Shark 6 Premium's 790 kg payload, and measured roughly 60 mm of rear compression without bottoming. Carrying and towing together is tighter: Shark 6 Premium weighs 2,710 kg and Performance 2,775 kg against the same 3,500 kg GVM. Performance at full tow has 375 kg for occupants, towing hardware, tub cargo and accessories. Put a number on it from the unhitched scale: 3,025 kg is 250 kg above the Performance's brochure kerb, leaving 125 kg; a 3,125 kg reading leaves 25 kg.

GVM and combined mass run out together at the full rating; the rear axle can tighten independently because position matters. loadmate holds all three live while a rig is packed, but it needs measured axle inputs to do that honestly on a Shark 6.

Which BYD Shark 6 to buy, and what to weigh before you tow

Match the variant to the van. Up to 2,500 kg ATM, BYD Shark 6 Premium is rated for the job and leaves 540 kg at full tow. From there to about 2,800 kg only Performance is rated, matching the dated Australian test band; beyond that, the cited full-rating test was on a proving ground and 375 kg remains in the ute.

Settle the hardware separately from the vehicle rating. ROVER's current approval certifies Performance to 3,500 kg and records full ADR 62/02 compliance. BYD's configurator makes its optional rear bar unavailable on Performance, while a dated May 2026 delivery report says the grade arrived with a factory receiver. Neither surface publishes that receiver's load label. The aftermarket X-Bar 03530XW sheet is only 2,500 kg and cannot prove or replace the factory part's rating. Before towing, inspect the receiver and ball-mount labels and ask a BYD dealer to match the VIN-installed part to both 3,500 kg trailer and 350 kg ball. The lowest component rating governs.

Then weigh it. Load the rig the way you travel, run it over a certified weighbridge axle by axle, and you have the figure no spec sheet gives you: how much of the rear axle's rating the ute was using before the van turned up. The Shark's variant and touring accessories both affect what remains for the trip. Get the loadmate app to put your measured ute weights, van and recorded gear against the relevant limits. For the measurement terms, the caravan weights guide sets out which of ATM, GTM and tow-ball mass each is measured against. Treat all of it as help with a loading decision. Use the vehicle and towbar approval information for their rated limits and a certified weighbridge ticket for the measured masses on that loading day; the tow belongs to whoever is driving it, which loadmate's safety disclaimer puts plainly. The useful reversal is what to carry away: the Performance adds 1,000 kg of vehicle tow rating while its extra kerb weight leaves 165 kg less payload at full tow, and its rear axle rating is 27 kg lower.
