Audi S1 vs BYD Sealion 7

What's the difference?

Cars this small shouldn't be this fast and useable at the same time, but the Audi S1 is. It isn't without its problems - the ride is harder even than the Fiesta ST which might weary some prospective buyers.

It's also a bit difficult to justify the price - in its basic form it's missing a few creature comforts that you'd expect in a $50,000 car - reversing camera, high-res screen, that sort of thing.

However, in the hot hatch world, those things don't matter. It has the bragging rights, the tech and the outright blinding speed to take on the bonkers Focus ST and equally zany Megane RS. And even the Audi S3.

The BYD Sealion 7 Performance is well-priced and well-equipped. It more than holds its own against its mid-size electric SUV rivals. It has great motor outputs and it handles comfortably on the road. There's a lot to like here but some of the technology needs to be tweaked.

The A1 is so small it starts to strain Audi's design language. When you cram on the S-style bumpers and raccoon-eyed trim on the hatchback, it's starts to look a bit busy.

It isn't quite a shrink-wrapped A3 - Ingolstadt's designers know better than that - but it's full of Audi design cues, such as the strong, light-catching character lines, distinctive LED daytime running lights and fondness for big wheels.

Inside is along the themes of the A3, with what are becoming Audi's trademark; round eyeball air-con vents, the manual fold-down screen familiar to Q3 owners (but smaller) and a good clear dash. The handbrake jars slightly as it feels cheap to hold and wobbles a bit.

The S Sport seats are big and comfortable, and the top half of the backs are capped in plastic, which was colour-coded on our car. The rear passengers will certainly get an eyeful of whatever terrifying hue you've chosen, so choose wisely.

Despite the five doors, the back seats are occasionals, like the Mini the A1 is gunning for, and the boot is very small, but okay for shopping for couples or singles.

It may be named after a sea lion but it doesn’t resemble the blubbery cuteness of the creature itself. However, its sleek dynamic styling and performance outputs do call forth some of the creature's water prowess. 

This prowess is hinted at by the 20-inch alloys which are fitted with Michelin tyres and red brake calipers. There’s some Porsche-like design notes in the wide swoopy nose and LED headlights. The rear is also quite handsome with its long LED band strip and narrow window giving it a sporty silhouette.

Head inside and the Performance showcases the best BYD cabin I've sampled. There are no strange accents or panelling like there are in the Atto 3. This proves that BYD can do premium well.

The quilted leather upholstery feels supple underhand and the sports seats with integrated headrests reminds you what it can achieve in a sprint.

The swoopy design is carried over inside with the door panels. The dashboard is simply styled but headlined by an enormous 15.6-inch display that can rotate between landscape or portrait mode. Some may liken it to an iPad but it works.

The panoramic sunroof keeps things bright and cheerful but there are some simplistic elements that are hard to ignore. Like the lack of buttons, minimalist mirror cover design on the sunvisors and a rather plain-looking centre console.

Everything else flows and my favourite feature inside is surprisingly the lever door handles! They're functional but cute.

The Sealion 7 is being offered in only two grades, the base Premium and the flagship Performance that we're testing for this review.

There are only four points of difference between the two grades. The Premium isn't all-wheel drive and doesn't include heated rear outboard seats, a heated steering wheel or dual electric motors like the Performance gets. That creates a $9K price hike to jump into the top-spec grade, bringing it to $63,990 before on-road costs.

It might be starting to sound expensive but it's still more affordable than most of its main rivals. This is because the Cupra Tavascan VZ is priced from $74,490 MRSP and the outgoing pre-update Tesla Model Y Performance comes in at $82,900 MSRP.

What do you get in the Sealion 7 Performance? A lot, it seems. Standard equipment includes electric front seats with heat and ventilation functions, adjustable under-thigh and lumbar supports, panoramic fixed sunroof and leather upholstery, a leather-wrapped steering wheel with mounted controls.

Technology looks top-notch with a crystal clear 360-degree view camera system, a rotating 15.6-inch multimedia system, 10.25-inch digital instrument cluster, coloured head-up display, dual-zone climate control, two USB-A and -C ports, 12-volt socket, V2L capability (via adapter), wireless Apple CarPlay and Android Auto, 12-speaker Dynaudio sound system, over-the-air updates, and satellite navigation.

There's also keyless entry and start, powered tailgate, BYD digital key (via smartphone app), tyre repair kit, rain-sensing wipers, dusk-sensing LED headlights and soundproof double glazed glass on both the windshield and front windows.

This is where the action is. The S1's tiny body packs a 2.0-litre turbocharged four-cylinder producing 170kW and 370Nm of torque. The S1 will streak to 100km/h in 5.9 seconds thank to the traction aid of quattro all-wheel drive.

All Audi S1s come with a six-speed manual

Despite a pretty solid hammering during its week with us, including more time than we'd have liked in Sydney traffic, the stop-start function helped deliver a pretty reasonable 10.2L/100km, however that's a long way over claimed 7.1L/100km.

All Audi S1s come with a six-speed manual, so dual-clutch haters can save the whining. The only downside from not having a self-shifter is the ECU can't deliver the boy racer farts, parps and crackles of the other S cars.

The Performance is all-wheel drive and is fully electric with dual motors, a squirrel cage induction motor located at the front and a permanent magnet synchronous motor at the rear. Together they produce up to 390kW of power and 690Nm of torque.

This gives the flagship grade a 0-100km/h sprint time of just 4.5 seconds. There’s obviously ample power to be had here which will delight EV fans who like that tummy-falling sensation when accelerating.

If you're buying the S1 as a comfortable urban runabout with a cool badge, you're half right. While the seating for front passengers is certainly supportive, the hard suspension tune will ensure you're well aware of road surface imperfections.

The S1 is a rocket

Thankfully, what it missed out on in the ride department it makes up for in every other way - the S1 is a rocket. The 2.0-litre turbo jammed under the bonnet has almost no lag and is paired with a slick six-speed manual that is terrific fun to manhandle through the gears.

The way the S1 picks up speed when it's on boost is addictive and licence-endangering. A flattened accelerator in second or third will obliterate just about anything this side of $100,000 and you'll be having more fun in this than big brother S3 because the chassis is more adjustable and there's a bit more life.

You can hear the turbo sing to accompany the bassy exhaust growl. Hit the massive brakes hard and the car remains stable even over rutted roads. Turning the wheel brings almost-instant turn-in, mashing the throttle again a fun little wriggle. It's superb.

It's tremendous fun point-to-point on a twisty road

You'll have to be a bit patient with the throttle to get the wriggle, though - give it too much too early and it will want to push wide, the quattro system shuffling power around to try and quell understeer while the electronic diff fiddles with the braking system to do the same thing. It gets there in the end, but you're better off meting out the power with your right foot for maximum rewards.

It's tremendous fun point-to-point on a twisty road - despite being a bit heavy for its size (1415kg), it's as chuckable as the next best thing, the Fiesta ST.

The Performance grade offers plenty of power that is delivered wickedly quick without feeling overwhelming when you have to accelerate. You still feel in control, which is very important when you have outputs like this does.

The steering is responsive and light enough for quick lane changes. The general on-road handling is quite refined but there is more roll in corners than you’d expect and this is the only time the power can make the handling feel a tad wobbly.

Surprisingly, there isn't a one-pedal function and the regen braking isn’t particularly strong. It’s difficult to ‘creep’ forward in this in stop/start traffic where it can feel a bit jerky at times, so it handles best on the open road.

Visibility is mostly good but the rear window is narrow and a digital rear-view mirror would have been welcomed in this model. Suspension is sports-firm but forgiving over bigger bumps. 

The 360-degree view camera and surrounding sensors makes this super easy to park and honestly, you shouldn’t have any trouble manoeuvring the Sealion 7.

The new Sealion 7 has a maximum five-star ANCAP safety rating from testing done in 2025 and scored well across its individual assessment criteria, scoring 87 per cent for adult protection and 93 per cent for child protection, respectively.

The Sealion 7 features nine airbags, including side chest airbags for both rows but it’s common to see these just on the front, so this is excellent. 

When it comes to standard safety equipment, it's almost a case of what doesn't it have? Some stand-out features include front and rear cross-traffic alert, blind-spot view monitor (which pops a video feed of your left blind spot onto the multimedia display) and child detection alert.

Other standard features include lane keeping aid, lane departure warning, adaptive cruise control, forward collision warning, rear collision warning, driver attention monitoring, 360-degree view camera system, and multiple parking sensors.

The autonomous emergency braking has car, pedestrian, motorcyclist and cyclist detection. For pedestrian, motorcyclist and cyclist detection, it is operational from 8.0 to 80km/h. For car detection, it is operational between 4.0 to 150km/h.

There are ISOFIX child seat mounts and three top-tether anchor points and the rear row is wide enough to accommodate three child seats side by side.
