Audi A1 vs Audi A4

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.

The Audi A4 allroad 40 TDI quattro S Tronic is a nice-looking wagon that’s fun to drive.

It’s packed with tech, adequately functional for daily life and it’s also capable enough off-road as long as the driving surface is nothing more challenging than well-maintained gravel or dirt tracks in dry weather, and you’re not planning a rough-and-tumble expedition into remote bushland.

As I mentioned earlier, the great thing about adventures is that you can scale them to suit you and your vehicle and the allroad offers a nice stepping-stone for people who’d like to experience the outdoorsy lifestyle, before perhaps diving deeper into it.

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 allroad’s overall look is part of a range-wide refresh and it certainly fits in with the line-up’s updated aesthetic.

Because I’m a bloke who spends the bulk of my time in 4WDs – traditionally bulkier vehicles rather than slim city-friendly wagons – I’m not totally enamoured of the Audi’s style, especially in terms of trip-packing practicality. However, I can certainly appreciate the appeal of its quite low, sleek and streamlined appearance, which its tweaked chunkier grille adds some gravitas to. It’s just not my cup o’ tea.

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. 

I’ll answer that question as a politician would – without actually answering the question.

The allroad’s interior looks good and certainly feels open and spacious, although the driver’s seat tends to feel a bit more snug as the dash is angled towards that position.

The new 10.1-inch touchscreen, home for most upfront functions, dominates the dash, in a good way.

The front seats are electrically adjustable with lumbar and driver memory.

There are plenty of places in which to put your everyday bits and pieces (including a decent storage bin/arm-rest), as well as charging points, including two USB ports, for your devices.

Need somewhere to put a cold beverage, mate? There are two cup-holders between driver and front-seat passenger, two in the fold-down centre arm-rest for the back-seat passengers, and bottle holders in all doors.

Back-seat passengers also get air vents, climate control, mesh seat-back pockets and grab handles. 

There is a 495-litre cargo space when the rear seats are in use, but that increases to 1495 litres when those seats – 40:20:40 split folding – are stowed away in the floor.

The Audi A4 allroad 40 TDI quattro S Tronic has a MSRP of $69,900 (plus on-road costs).

It has a 2.0-litre four-cylinder turbo-diesel engine unit (140kW/400Nm), a seven-speed S tronic automatic transmission, and Audi’s quattro all-wheel drive system. 

In standard guise this allroad’s features list includes a new 10.1-inch touchscreen (with Apple CarPlay and Android Auto), DAB+ digital radio, an Audi 10-speaker stereo, wireless charging for Qi-enabled smartphones, Audi’s Virtual Cockpit (a 12.3-inch digital display), smart key with push-button start, leather trim, three-zone climate control, as well as LED headlights, 18-inch alloy wheels, illuminated door sills, and overall tweaked exterior and interior styling.

It also has AEB with pedestrian detect, lane change warning, rear cross-traffic alert, front and rear parking sensors and a reversing camera.

But our test vehicle has a few different features and a fair few extras. Our allroad has a ‘price as tested’ of $75,681 (plus on-road costs), because it has Assistance plus package ($2900), which includes a raft of driver-assist tech, such as adaptive cruise control, active lane assist, collision avoidance assist, high beam assist, head up display, park assist (helps to steer the vehicle into a parallel or perpendicular parking space), as well as a 360-degree-view cameras 

It also has 19-inch Audi sport alloy wheels in 10-Y-spoke design ($1350), instead of the standard 18-inch alloy wheels in 5-V-spoke design, and metallic paint (Mahattan grey, $1531).

Note: when we were conducting this test, Audi announced that, among other things, it would release a new-gen A4 allroad quattro 40 TDI in early 2021 that would have an extra 10kW more than our test vehicle, so it’ll be a 150kW/450Nm machine.

For those of you into hot laps, the current-generation achieves 0-100km/h times of 7.9 seconds; the new A4 allroad quattro 40 TDI is claimed to achieve that mark in 7.3 seconds.

Pricing for the upcoming 150kW A4 allroad quattro 40 TDI as standard was set to be $70,700. 

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.  

The Audi A4 all road 40 TDI quattro S Tronic has a 2.0-litre, four-cylinder turbo-diesel engine, producing 140kw at 3800-4200rpm and 400Nm at 1750-3000rpm.

It has a seven-speed S tronic automatic transmission and all wheel drive.

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.

It has claimed fuel consumption of 5.2L/100km (combined), but we recorded actual fuel consumption on test of 8.4L/100km – driving in soft sand likely negatively impacted that figure.

It has a 61-litre fuel tank.

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.

For a bloke who spends a lot of time in big, tall and bulky 4WDs, I felt like I was driving a go-kart. It’s that low, but it’s also that much fun – and it’s a very different driving experience to what I’m used to.

The allroad is 4762mm long, 1847mm wide and 1430mm high, and has a listed kerb weight of 1720kg. So relative to the 4WDs I usually steer around, this is light and low slung. It’s more car than SUV, that’s for sure.

Acceleration is rather punchy (the engine and auto are a decent match-up), steering is light but precise, and you can cycle through drive modes (efficiency, comfort, auto etc) to set up vehicle characteristics to suit your driving style and conditions.

The quattro all-wheel drive system helps to keep the allroad planted and composed at all times. 

Ride is on the sharpish side of firm and you do tend to feel every irregularity in the road surface – it is long and low and on low-profile rubber afterall.

The virtual cockpit plus – a 12.3-inch high-resolution colour display – offers a comprehensive read on all things to do with the allroad.

Throw around your superlative of choice – “sporty” and “dynamic” fit this allroad well – but I’m loathe to gush about its on-road performance much more than that because I reckon if any motoring journos are reading this – many of whom spend the lion’s share of their time swanning about in sports cars – they would have already choke-spat out their dirty chai with surprise by now.

The Audi A4 all road 40 TDI quattro S Tronic has the maximum five-star ANCAP safety rating.

It has eight airbags (dual front, front side, side bags front and rear, and curtains front and rear), as well as AEB with pedestrian detection, lane change warning, rear cross-traffic alert, a reversing camera, and front and rear parking sensors.

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.
