BYD Seal 6 Touring: We Drive 993km From Sydney to Melbourne Without a Fuel Stop

I covered exactly 993.1 kilometres to get here from Sydney and arrived with 28 kilometres still left in the tank. I could have kept going.

Ten identical Seal 6 Tourings sat nose to tail in the car park at BYD’s Alexandria dealership, engines off, waiting for a job most wagons never get asked to do. The brief was simple. Sydney to Melbourne, just over 1,000 km, on one tank of fuel and one charge of the battery. No servo stops. No chargers.

BYD’s DM-i 5.0 hybrid system is the most efficient hybrid drivetrain the brand has built, rated at 46 per cent thermal efficiency. That’s the number behind the claim. This drive was about testing what it means on the road, over two days, with a wagon full of luggage, a co-driver, and every kind of surface between Sydney’s inner south and Melbourne’s outer north.

Day One: Sydney to Albury

We loaded up two people per car and started swapping driving legs on the Hume. Riding shotgun for the first stint, I got to watch the trip computer instead of the road. BYD claims the Seal 6 Touring’s DM-i 5.0 system is good for around 100 km of EV-only driving on the WLTP cycle, and the engine kicked in right on 94 km, with the battery sitting at 19 per cent state of charge. Close enough to the claim to not argue about it.

Riding with me for that first leg was Riz, a fellow reviewer from CarLoop Data. He took over for the next stint and by the time we pulled into Marulan for our first stop he’d covered about 150 km without complaint. His read on the wagon was straightforward: comfort and space, there’s just so much of it, and once you stop listening for the engine cycling on and off, you stop noticing it.

I took over after Marulan, and by the 200 km mark the trip computer was claiming over 1,400 km of range left. Enough, in theory, to get us past Melbourne and halfway to Adelaide. That number says more about how conservatively the system estimates range than about physics, but it’s a useful reminder of how much buffer this car carries.

With the target state of charge set to 50%, the battery climbed back up into the low thirties without me plugging in anything. The DM-i system was quietly banking leftover power from the engine’s motor-generator rather than burning it off, which is the 46 per cent thermal efficiency claim doing its job in practice. That engine is an Atkinson-cycle 1.5-litre, the same broad approach Toyota uses in the Camry and RAV4, but BYD’s tuning extracts more from every drop of fuel: 46% against the low 40s you’d expect from a comparable Toyota hybrid.

The ride on the highway is comfort-tuned rather than sporty, compliant without being soft, and exactly what a car built for this kind of trip should feel like. Where the Seal 6 Touring gives ground is acoustic isolation. The windows are single-pane rather than acoustically laminated, and road and wind noise, particularly from passing trucks and the door mirrors, make it into the cabin more than in a car with proper double glazing. Turn the radio on and you’d probably stop noticing it.

Lunch was at the Sir George, a heritage pub in Jugiong dating back to the 1850s, one of the better reasons to take the Hume instead of flying.

Riding in the back seat for the next leg gave a different read on the car. The seat base is softer than the front pews, there’s genuine legroom even with the front seat set for a taller driver, and the cabin gets noticeably quieter once you’re not sitting next to a door glass. Rear passengers get their own air vents, USB-A and USB-C charging, and glass overhead courtesy of the panoramic roof.

We stopped at Little Billabong, a rest area on the Hume, to check the boot. BYD quotes 670 litres, measured to the roofline rather than the parcel shelf, so treat that as a ceiling figure rather than a guarantee. In practice, a cabin bag and a small stack of backpacks for two people filled a fraction of it, with plenty of room to load higher if you needed to.

Day one finished in Albury: 541 km down, on schedule, nothing to report mechanically.

Day Two: Alpine Roads

The second day traded highway droning for the foothills of the Alpine region, narrow and twisty, with enough crests and potholes to test any wagon’s composure. Riding as a passenger for the first stint, the body control was genuinely good. Minimal roll through the direction changes, no sense of being thrown around on the rougher sections. One pothole big enough to worry about barely registered.

After a stop in Myrtleford, I got behind the wheel and, courtesy of a wrong turn, ended up on a fairly long stretch of unsealed road through the high country. Corrugations, potholes, a few washed-out sections rebuilt by hand: the Seal 6 Touring handled all of it at around 80 km/h without drama, which says something about the suspension tune for a car that will spend the vast majority of its life on bitumen.

Climbing into the alpine foothills proper, the battery dropped to 12 per cent state of charge and the engine got noticeably louder working to keep it there. BYD’s hybrids are known to dial back power at very low states of charge, and I was watching for it. At 12 per cent, on a sustained climb, there was no drop in response that I could feel. This is a comfort-oriented wagon, not a driver’s car, but the twisty alpine roads were genuinely good fun in it, helped by a glasshouse and sunroof that make the most of the scenery on the way up.

Driver Assists and Tech

BYD’s ADAS suite has come a long way from the overly chatty systems on its earlier models. The warning tones are far more subtle now, a faint chime rather than a blaring alert. The driver monitoring system is still a little quick to flag you for glancing away from the road, easily switched off in the menus if that bothers you.

Lane keeping and adaptive cruise are genuinely trustworthy on the open highway, tracking the centre of the lane without the ping-pong behaviour that makes some systems annoying to leave switched on. On tighter, narrower back roads it’s a different story. The odd jolt, or a corner it doesn’t quite track cleanly, suggests the calibration needs another pass for anything short of a well-marked highway.

Inside the Cabin

We stopped near Kinglake, on the final leg into Melbourne, to properly look at the interior. It’s a genuinely different design language to anything else wearing a BYD badge. The dash top flows down at the edges the way the Atto 3’s does, but the flat panel behind the steering wheel wears a matte finish rather than the piano black gloss BYD leans on elsewhere in its range, with ambient lighting either side that lifts the whole thing at night.

The steering wheel is a carryover from the BYD Seal EV, and it’s one of the best wheels available at this price point, full stop. Controls sit logically either side, the driver’s display is clear even if there’s no head-up display, and the 12.8-inch central screen runs BYD’s DiLink system with wireless Apple CarPlay and Android Auto that connect without fuss.

Storage is well thought through: a 50W wireless charging pad, a deep centre console with a neoprene-style lining, a 12-volt socket and USB ports tucked below. Front seats are heated, ventilated, and genuinely comfortable over a full day of driving, which matters more than most spec sheets let on. The panoramic glass roof runs the full length of the cabin, with the front section opening and a manual shade if you want it blocked out entirely.

The Final Numbers

We rolled into the Novotel at Melbourne Airport having covered exactly 993.1 km from Sydney’s Alexandria, with 28 km of range still showing on the dash. Total fuel used across the drive was 53.7 litres. Run that through the maths and you get 5.41 L/100 km.

BYD’s own claimed figure for the Seal 6 Touring under favourable conditions is 0.8 L/100 km, but that number assumes a full battery doing most of the work. Two days of sustained highway and mountain driving on a battery held near its floor is a much harder test, and 5.41 L/100 km against that backdrop is a genuinely strong result. Other cars in the same convoy landed in a similar band, mostly in the high fours to mid fives per 100 km, which says the number wasn’t a fluke of one lucky car or one gentle right foot.

Once you’re home and plugged in, none of that petrol maths applies. The Seal 6 Touring will do daily commuting and school runs on its 100 km of WLTP electric range without troubling the tank at all.

Pricing and Rivals

The Seal 6 Touring is sold in Australia in a single Premium grade, priced from $39,990 plus on-road costs. That undercuts every plug-in hybrid SUV on sale and makes it, at the time of writing, the cheapest wagon of any kind on sale in the country. It’s backed by a six-year, 150,000 km vehicle warranty, an eight-year, 160,000 km battery warranty, and 18-inch wheels on Continental rubber, which will be a cheaper ongoing proposition than the 19s and 20s fitted to most rival SUVs.

There’s no direct wagon rival at this price. The closest competitors are PHEV SUVs: Chery’s Tiggo 7 Super Hybrid starts at the same $39,990, and Jaecoo’s J7 Super Hybrid opens from $47,990. Against either, the Seal 6 Touring trades outright height and presence for a lower loading floor, a lower centre of gravity, and genuine wagon manners.

If you’d rather have the sedan, the compromise is a smaller battery, shorter EV range, and less standard equipment for $5,000 less. For most families cross-shopping this against a Camry Hybrid or a mid-spec SUV, the Touring’s extra outlay buys real usability.

Back in Melbourne, the job for this car changes completely. Plug it in overnight and the Seal 6 Touring can handle the school run and the weekly shop on electricity alone, saving the DM-i system and its 46 per cent thermal efficiency for the trips that actually need it.
