Audi A1 vs BYD Sealion 5

What's the difference?

If you’re eager for a sporty compact hatchback with premium design and luxury car badges, the Audi A1 40 TFSI is a very, very strong contender. It’s fast, fun, and functional for a little hatchback. It’s just very expensive, and for most people the $10K cheaper 35 TFSI model will tick most of the boxes. I’d recommend you drive it before signing on for the top-spec model.

Cars that don’t always appeal to enthusiast buyers are often seen by manufacturers as a way of not bothering with the dynamics. Good enough is, apparently, good enough. Thankfully, BYD hasn’t taken that path here and the local suspension tweaks have turned what could have been a me-too product into a bit of a dynamic class leader. And even if buyers can’t verbalise the benefits of that, they will still be subliminally enjoying them with every kilometre.

The other stand-out feature is the price-tag which represents an awful lot of car for the money. And, in such a price-sensitive market as this one, that will get the BYD over the line for a lot of families. That it also offers a vastly better driving experience simply makes the value equation – and the purchasing proposition – even stronger.

I don’t think I’ve seen a better transformation between generations than the current A1. In its previous guise it was bubbly and cute, but now it’s an angular brute.

This version’s S line sports body kit and funky 18-inch alloy wheels certainly help in that regard, but even the standard lighting signatures - LEDs front and rear - make it stand out as anything but a cutie pie city car.

The good news is that it hasn’t grown too much, either. Sure, it is a bit bigger, measuring 4029mm (on a 2563mm wheelbase), 1740mm wide and 1409mm tall. The last one was smaller (3973mm long on a 2469mm wheelbase, 1746mm wide and 1422mm tall), but this one isn’t elephantine in its proportions and so remains simple to park and squeezy enough to be considered a Light Car by industry standards.

And there are some really, really playful colours available. Like this Turbo Blue (which is only for this spec), and Python Yellow. There’s also black, green, red, three different greys, and two whites. The only issue is that flat white (Cortina White) is the only no-cost paint option. The rest will set out back $490 (for Tioman Green or the blue you see here) or $990 (for the rest). 

And then you can option the paint with a black roof, for $1380 combined with blue or green, or $1880 in all the other colours. The black exterior styling pack adds black highlights around the grille and on the front and rear bumpers. Those little Audi four-ring stickers on the rear doors are standard on this spec.

But to be honest, it stands out no matter what colour you choose, and that’s enough to get people’s heads turning on the street. And the interior design? Well, it has some good and bad points. See the interior pictures below to make up your own mind. 

The interior of the Sealion 5 feels pretty well-made and there are soft-touch surfaces on most of the touch-points. The steering wheel, too, is thick and chunky and nice to hang on to. But there’s a lot going on in terms of different colours, textures and surfaces, and it can all look a bit busy, despite the high-tech boardroom overall flavour. It’s also worth mentioning the trim material is synthetic but does a great job of looking and feeling like real leather.

Externally, there’s not a lot to grab the eye. Sure, it’s not an unpleasant looking vehicle, but neither does it stand out from the mid-size SUV pack. At least BYD decided against those cheap-looking plastic tack-ons on each wheel-arch.

There are elements of the A1’s cabin design that are tremendous. And other bits that are not so tremendous. 

The bad bits include the fact you’re paying about $50,000 on the road for a car that has hard plastic just about everywhere the eye can see.

The good bits are that the textured plastics on the dash are beautiful, and so are the designed elements on the doors. I love the door handles, I love the metallic finish, I love the layout and I love the way it makes you forget that you’re in a luxury-branded car with hard plastic all around you.

The media screen and digital dashboard help, too - it feels technical and premium in the driver’s seat as a result. The graphics are crisp and clear, the menus are mostly easy to navigate, but I had some issues getting Apple CarPlay to work. It has wireless CarPlay, and I had it plugged in, so perhaps that was confusing things.

But the Audi media system also includes Audi Connect in this spec, meaning there are realtime map, traffic and hazard updates, plus a Wi-Fi hotspot, fuel prices, parking, weather and Google maps and services. It’s high-tech, and if that’s what you like, this is definitely going to please you more than a Mini Cooper.

Practicality is good, with bottle holders in all four doors, cup holders between the front seats and a covered centre console and wireless charging bay in front of the shifter. In the back, storage is sparse: aside from the door pockets, there’s nothing - no cup holders, no map pockets. 

There is enough space for four adults in the A1, so if you plan to take your mates to brunch or if you’ve got young kids, you should be comfortable enough in here.

I had the driver’s seat set for my own height (182cm) and I was able to slide in to the rear seat without much fuss at all, with adequate knee and toe room, and decent headroom too. Try and fit three across the back and it’ll be uncomfortable, unless those three are very slim. 

There are dual ISOFIX child-seat anchor points and three top-tether points, and the seat structure is pretty flat, making fitment of these types of seats simple enough.

The boot capacity is good for a car of this size at 335 litres, which is a solid 20 per cent bigger than before. You won’t find a spare under the boot floor, though, as all A1s have an inflator kit. The back seats fold down to allow 1090L of cargo capacity, but there’s a ledge you have to contend with if you’re trying to load larger items in. Maybe skip the IKEA trips in this one, then. 

Here’s the other big shock relative to the price-tag of the Sealion 5: This is not a small car. Based on the price, you might have been thinking the vehicle would be a compact SUV. And you’d have been wrong. This is a proper mid-sized SUV with room for five and luggage and an overall length of 4.7 metres and change. And to put that into some kind of perspective, that’s just 30mm shorter than the Sealion 6 which costs about $9000 more at its starting point.

The wheelbase is long, too, and the 2712mm between the axles helps make the interior even more spacious. That means there’s lots of stretching room in the front, but also that a grown adult can comfortably sit in the back seat behind another grown adult at the wheel and still have enough room in every direction. The window sills are commendably low in the rear seat, too, ensuring even littlies can see out.

The biggest problem in the back is that the seat cushion is a bit flat, but, like the front chairs, it’s still pretty plush.

With all five seats in place, the Sealion 5 boasts 463 litres of luggage space and the cargo area is well done with storage pockets at each side, a light and an under-floor tray designed to transport charging cables and a tyre repair kit. Yep, that’s right, there’s no spare tyre of any sort here. No surprise, really.

Fold the rear seat down and you’re suddenly looking at 1410 litres of cargo space and your SUV is now a panel van.

As well as the dual-zone climate control, the Sealion 5 also offers a single USB -C and a USB-A charging port in the front and rear compartments.

The Sealion 5 also offers a V2L (Vehicle to Load) function, meaning it can power camping or on-site work equipment and even act as your home’s battery.

The plug-in hybrid in question is the BYD Sealion 5. It has a claimed EV-only range of better than 100km, relatively quick charging, a decent sized battery, adequate performance, enough interior space for a family, good safety and lots of equipment. Oh, and it costs just $33,990, before on-road costs, in its entry-level Essential form. Incoming!

Equipment-wise, that sub-34K sticker gets you a 10.1-inch central info-screen, an 8.8-inch driver display, digital radio, a six-speaker stereo, wireless connectivity for Android Auto and Apple CarPlay and dual-zone climate control.

Throw another four grand on the table and you move up to the Premium version which adds plenty of kit for the $37,990 ask. That includes a panoramic sunroof, automatic tailgate, roof rails, heated and electrically folding mirrors, one-touch power windows, a six-way powered drivers seat and four-way powered co-pilot’s chair, a heated and ventilated driver’s seat and wireless charging.

The step up from Essential to Premium also includes a battery upgrade, and we’ll cover that off in the Under the Bonnet section below.

This 40 TFSI model is the big humdinger in the range. It has the donk, right?

Yeah, it’s a 2.0-litre four-cylinder turbo-petrol engine, which is a full litre bigger in capacity than the base model car. And it’s the same engine fitted to the Polo GTI - a proper hot hatch!

It doesn’t quite have double the power and torque of the entry-level 30 TFSI model, but it does have solid outputs of 147kW (at 4400-6000rpm) and 320Nm (from 1500-4400rpm). That’s enough to slingshot this A1 from 0-100km/h in a hot-hatch-rivalling 6.5 seconds, according to Audi.

Unlike the lower grades, it runs a six-speed dual-clutch automatic, which it needs because it has so much torque. The 30 and 35 TFSI variants have a seven-speeder. All of them, including this one, are front-wheel drive.

There is no quattro/all-wheel drive A1 this time around, and there won’t be an S1, either. So this is it if you want your kicks in a compact car from the Ingolstadt-based brand.  

Both variants of the Sealion 5 have the same driveline – mostly. They each use a 1.5-litre petrol engine teamed with a single electric motor, both driving the front wheels. Unlike the bigger Sealions, there’s no all-wheel drive version. Power peaks at 156kW and torque at 300Nm.

Why a non-turbocharged engine? BYD tells us the non-turbo engine helps keep cost out of the vehicle and, since the engine really only runs to power the electric motor and charge the batteries, it does so at a relatively constant engine speed, negating the need for a wide spread of petrol power.

The only major difference is that the Essential version has a 12.9kWh battery-pack, while the Premium gets a bigger, 18.3kWh pack for longer range, but precisely the same output and, therefore, performance.

A single-speed transmission is part of the BYD driveline package, also made possible by the fact that the vast majority of the driving of wheels is done by the electric motor.

Claimed fuel consumption is rated at 6.4 litres per 100 kilometres. You might see close to that on a highway drive, but if you’re primarily city-dwelling like me, then expect higher.

I saw an average of 10.1L/100km during my urban review of the A1 40 TFSI. That was with stop-start engaged the whole time, and the occasional squeeze of the accelerator to test out the claimed acceleration.

Fuel tank size for the A1 is just 40 litres, so if you’re doing what I did with this grade of A1, you can expect to visit the servo every 400km or so.

The Premium’s bigger battery claims to up the official NEDC range from the Essential’s 71km to 100km. BYD reckons with the 52-litre fuel tank brimmed and the car operating at its claimed 1.2 litres per 100km efficiency, the range of either version is just on 1000km. In the real world, that’s likely to be closer to 800km (especially with some highway running thrown in) but it’s still one heck of a solution to range anxiety.

There’s no DC charging function for the Sealion 5, so forget about commercial fast chargers. But on a 3.3kW AC power outlet, the maker claims the Essential can reach full charge in under four hours, while the Premium’s bigger battery will take under six hours to fully charge. A Type 1 charge cable is included.

You shouldn’t be surprised to know that the A1 40 TFSI feels a lot like a Polo GTI to drive. It’s quick, it’s entertaining, it’s refined… it’s just about 50 per cent more expensive.

That mightn’t matter to you or factor into your considerations. I just want to point out that you can get a car that’s just as good to drive as this one, and still with a premium German brand attached to it, for a lot less.

The A1 does have it’s own spunk, though. It has a more masculine character, more aggressive styling, and more delightful interior design.

But it also has steering that is predictable and easy to judge, helping it feel nimble and grippy. From tight twisty roads to roundabouts, you’re going to be having fun in the A1 if you’re tooling around town. 

It feels planted and grippy - aside from some front-wheel spin during take-offs if the tyres are cold - and you might notice the suspension can be a touch noisy as it pitter-patters over inconsistencies in the road surface, but the ride is firm yet controlled, offering enough comfort over potholed city roads and speed humps for this tester. And there are several of each of those obstacles on my daily drive to work.

The engine is a sweetheart, offering brilliant linearity to its power delivery. It pulls hard from low in the rev range, meaning you’ll be able to zip through traffic without much hassle at all. The powertrain is super responsive to inputs at speed, especially if you put it in Dynamic mode, which also allows you to hear some pops and crackles from the exhaust system. 

That said, there is some vibration, shuddering and hesitation at low speeds, which is a combination of the stop-start system kicking in and out, a small amount of turbo-lag from the engine and some shuffling behind the scenes from the dual-clutch transmission. You might find the lurchy nature of the first-gear take-offs to be a bit hard to get used to, especially if you spend a lot of time in bumper-to-bumper traffic. 

While this is an Urban Guide review focused on city driving, I thoroughly recommend you find a quiet stretch of twisty road outside the city limits. You won't be disappointed.

You don’t have to drive very far to realise that the local input into the Sealion 5’s suspension and steering have been worth the effort. BYD Australia has a local engineering team on call these days, and it shows here.

Actually, the steering is not the highlight; it has some weight but not a whole lot of feel, or, indeed, feedback for the driver. The ride and handling combination is what stars. Obviously well-damped, the suspension allows for a ride that is both complaint and quiet, without causing the car to wallow around like some jacked-up designs can with their higher centre of gravity.

In fact, the BYD is athletic to the point where keener drivers will find it an entertaining drive; hardly something that can be said for the majority of medium SUVs.

Performance is strong without being overwhelming and even though the Sealion 5 has that signature electric-drive feeling of effortlessness, the accelerator pedal has been calibrated to avoid the neck-snapping surge of grunt off the line. As such, it emerges with a fairly flat acceleration curve, and no hint that the petrol motor is cutting in or out.

Until, that is, you bury the throttle all the way at which point the petrol engine takes a few second to join in. And when it does, it’s pretty vocal – shrill, almost – as it catches up with the rest of the car and starts directly driving the wheels. To be fair, though, this is not going to be a common occurrence in everyday life thanks to the flexibility of the petrol-electric system for 99 per cent of circumstances.

On the move, the cabin is perhaps most notable for its soft, plush seats that are a nice change from the church pews of some manufacturers. And although the driving position is about right, taller drivers might prefer a steering column that extends out another few millimetres.

The driver display screen is another source of annoyance. It’s pretty small and contains lots and lots of information, to the point where the typeface is too small to be read on the run by anybody who relies on reading glasses.

Passive safety in the Sealion 5 starts with no fewer than seven airbags including full-length side-curtain bags. 

There’s also a front-centre airbag, something we’d like to see in more cars, particularly at this price-point. Child restraint points in the rear seat are the ISOFIX type.

The BYD gets pretty much the full suite of driver aids, including autonomous emergency braking, blind-spot monitoring, rear-cross traffic alert with active assistance, stability control, active cruise-control, traffic-sign recognition, front and rear collision warning and tyre pressure monitoring.

The Sealion 5 also incorporates a driver-attention monitor which seems better calibrated than some earlier efforts from some of the Chinese carmakers. Also improved in calibration terms is the lane-keeping assistance which is still too violent for our tastes, but more subtle than some of the competition’s systems. But while the savagery of this system has been toned down, it appears to have been at the expense of sensitivity and, time and time again, the cameras missed road markings that were faded or dirty.

The major safety benefit in paying more for the Premium variant is the addition of front parking sensors and a 360-degree camera instead of the Essential’s simple reversing camera.

The Sealion 5 has not been ANCAP tested as yet, although BYD says this is largely down to ANCAP’s scheduling rather than any hesitance on BYD’s part.

While the VW Polo GTI that this spec of A1 shares plenty with is backed by a five-year/unlimited kilometre warranty plan, the Audi-badged compact hatch still has a lesser three-year/unlimited kay cover. 

The A1 requires servicing every 12 months or 15,000km (just like a Polo), and there’s a pre-pay service pack you can roll into your finance if you so choose.

That service plan covers either three years/45,000km of driving ($1480) or five years/75,000km ($1990). In the case of the five-year plan, Audi is actually better value than the Polo GTI (which costs $2200 for pre-pay). 

Where is the Audi A1 built? You might be surprised to learn the answer is Spain.

Like other BYDs, the Sealion 5 comes with a six-year/150,000km warranty. Some of the competition have unlimited kilometre warranties, but to be honest, 150,000km in six years is going to be beyond the need and aspirations of most owners.

The EV battery is covered by an eight-year/160,000km warranty, and let’s not forget, BYD was a battery manufacturer before it started making whole cars. Certainly, the company is very bullish about the quality and safety of its 'Blade' battery technology, claiming it easily passes the technically-daunting 'nail-puncture' test.

BYD plans to have capped-price servicing for the Sealion 5, but no pricing announcements have been made yet.

Servicing also falls into line with other BYD models, so that means 12 months or 20,000km intervals.
