Audi RS3 vs Audi A4

What's the difference?

The Audi RS3 is a special hot hatch and sedan I’m so glad I experienced before its five-cylinder engine is inevitably retired due to emissions regulations. Full of character and charisma, this car is far from a rational purchase, pitched at boy racers who don’t want to grow up just yet.

From a value perspective, too, while the asking price has crossed the six-figure threshold and the option prices add thousands, it’s still much cheaper than the Mercedes-AMG A45 S. Make of that what you will.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

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.

Audi has made some subtle tweaks to the RS3 that has somehow made this snarling hot hatch look even angrier.

Up front there’s a new fascia featuring more open sections, which in turn improves air flow. A black styling package is now standard so it almost looks like the entire front is open and ready to eat you alive.

The matrix LED headlights now have a darkened finish which adds to the menacing look. There are new signatures, including a special chequered flag one for the RS3 which looks top notch.

Around the side it surprises me just how much wider the front is compared to the rear. Both have big, muscular haunches, but it shows this hot hatch is a bit of a bulldog. I’m a big fan.

These haunches stand out even more when you opt for the new Daytona Grey Matte exterior paint. While the extra $11,400 for the privilege makes me wince, it looks sexy on this car.

The standard 19-inch ‘Y-spoke’ alloy wheel design remains unchanged from the pre-update car, though there’s a new, optional ‘cross-spoke’ design that looks delicious (and tricky to clean).

At the back there’s still the classic RS dual exhaust tip motif which looks mean and it’s surrounded by a new black rear diffuser with a motorsport-inspired vertical red reflector in the centre.

The new LED tail-light signature with the vertical slats is so clean and neat. It looks particularly great in low-light situations or at night.

Inside, the biggest change is the new RS steering wheel with the flat top and bottom. As standard it’s wrapped in perforated leather, but with the optional RS Design package it’s wrapped in 'Dinamica' synthetic suede. I much prefer the standard leather-wrapped unit as the Dinamica likely won’t last in the long run, especially if you’ve got clammy hands.

Other changes include more interior ambient lighting on the door cards through small slits, as well as a new shift-by-wire gear selector. The digital instrument cluster and touchscreen multimedia system set-up remains unchanged which is no bad thing because they look fantastic.

It’s disappointing Audi has stuck with an extensive use of piano black on the centre console because this gets dusty and grimy very quickly, and then can get scratched easily when wiped clean. It now also features on the steering wheel buttons, which are frequent touchpoints.

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.

The RS3’s standard sport front seats are deliciously comfortable and offer plenty of electric adjustment. This means people of any size and stature should be able to find their desired seating position.

Thanks to the electric lumbar there’s also a massage function for the front seats. This is pretty cool to flick on and relax into, but I wish the massage was a little stronger.

While the new steering wheel looks cool interacting with the buttons on it can be a bit of a hassle. They’re touch-sensitive but do have a satisfying click if pressed harder.

There were moments where I accidentally clicked on the buttons during intensive track driving as my hands were at the nine and three o’clock positions. Not the best thing when you’re meant to be focussing.

The digital instrument cluster offers so much configuration you won’t know what to do with yourself. There’s even a new rev counter design especially for the RS3 which looks very cool.

Moving across, the touchscreen multimedia system is classic Audi. It’s easy to navigate around and hard to get lost in the sub-menus. There’s also wireless Apple CarPlay and Android Auto connectivity which is virtually a given now.

While you need to use the touchscreen for a number of features, I appreciate how Audi has retained so much physical switchgear up front. It’s particularly handy to have physical toggle switches and a small digital display that’s separate from the touchscreen for the climate control.

Another piece of physical switchgear I like up front is the rotary dial for the media controls on centre console. It’s much like an iPod, allowing you to change the volume if you rotate your finger on it like a click-wheel. Major throwback vibes.

In terms of storage up front, it’s decent but not outstanding. There are two cupholders, a wireless phone charger, a centre console box as well as a lockable glove box.

Moving to the second row, it’s clear it’s more for the sake of it, rather than having a space you’d want to use all the time. At a leggy 182cm tall, I have minimal legroom behind my own driving position.

With headroom, it’s adequate in the hatchback and not great in the lower-slung sedan. I need to kink my neck in the latter to fit, which isn’t comfortable.

The second-row bench seat is comfortable, offering enough support for short-to-medium trips. I wouldn’t want to get stuck back there for too long, however.

In terms of amenities, there are air vents mounted on the back of the centre console with a dedicated third zone of climate control, two USB-C ports, nets on the seat backs as well as a fold-down centre armrest with cupholders.

At the back there’s a power tailgate for the hatchback, however the sedan only has a power-opening boot lid. This means you need to manually shut it, which isn’t uncommon for sedans.

Boot space in the RS3 is a weak spot due to all the componentry for the all-wheel drive system and the tricky rear clutch set-up. There’s only 282L for the hatch and 321L for the sedan, which isn’t much.

In reality, however, the boot space is still usable. It’s fairly square and there’s barely any boot lip, meaning you can slide things in and out with ease.

Boot-related amenities include a netting system to keep things from sliding around, a light, some hooks and a 12V socket. There’s also a parcel cover for the hatchback.

Unfortunately there’s no spare wheel of any kind under the boot floor in the RS3 as this is where the 12V battery lives. Instead there’s a tyre repair kit. This isn’t uncommon in performance cars, though it’s disappointing if you frequently travel in the country, away from tyre repair shops.

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. 

The Audi RS3 is still powered by a 2.5-litre turbocharged five-cylinder petrol engine which produces an unchanged 294kW of power and 500Nm of torque.

This is mated to a seven-speed dual-clutch automatic transmission with drive sent through an all-wheel drive system.

Audi claims both versions of the RS3 can do the 0-100km/h sprint in just 3.8 seconds, which is technically 0.1 seconds faster than a Mercedes-AMG A45 S. Top speed is electronically limited to 250km/h.

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.

The Audi RS3 sedan is claimed to consume 8.2L/100km, whereas the RS3 hatch is claimed to consume 8.3L/100km, both on the combined (urban/extra-urban) cycle (ADR 81/02).

Both body types come with a 55L fuel tank and require a minimum of 98 RON premium unleaded petrol.

During my testing I saw an average of 9.6L/100km according to the trip computer. We did around 200km of higher speed driving heading east out of Melbourne, including some spirited sections.

Our on-test figure translates to a range of 570km on a full tank of petrol.

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.

Spoiler alert, it’s a cracker.

Starting up the RS3, you’re instantly aware you’re behind the wheel of something special. Audi has made the start-up more “emotional” with this update and also “optimised” the exhaust flap control for more five-cylinder growl across a wider rev range.

When you’re on the boil, this five-cylinder sounds so fantastic. It’s the clear centrepiece of this car and I’m so happy Audi has continued to offer it.

However, thanks to the addition of a petrol particulate filter (PPF) with this latest-generation model it sounds a little muted in everyday driving. Call me a boy racer, but I want more noise.

Staying on the engine, it’s full of character and gets this small hatch and sedan moving along with ease. Even though the outputs are unchanged with this update, it’s still more than enough; 0-100km/h in 3.8 seconds shows it's more than enough.

The seven-speed dual-clutch automatic transmission in this car keeps the acceleration feeling relentless with snappy gear changes at a moment’s notice. It’s particularly fun taking control of moving between the ratios with the paddle shifters.

In slow-moving traffic, however, the dual-clutch can get a little lost and stuttery, which is a classic characteristic of this kind of transmission.

As standard the all-wheel drive system remains neutral, keeping the front and rear balanced and in check. However, if you flick to the ‘Dynamic’ drive mode you get more rear-biased action which is fun when you exit a corner with some extra heat.

There’s also still a ‘RS torque rear’ drive mode which is essentially a drift mode. Unfortunately we didn’t get to sample this during the launch program.

Additionally, there’s an ‘Individual’ mode that allows you to choose your own destiny. You could spend hours here fine-tuning your desired drive mode which is both great to see but complete nerd-core.

Like the pre-update car, there’s an electronically controlled multi-disc clutch on the rear axle which actively splits the torque between the rear wheels. However, it’s been "optimised" to allow for quicker cornering.

While this is hard to gauge without testing the pre-update and current car back-to-back, the RS3 is so dynamic it feels like you only scratch the surface on public roads. Thankfully we got to see how far we could push it on Haunted Hills, which is a fantastically complicated hill climb circuit in eastern Victoria.

In terms of the steering, there’s a progressive rack as standard which ramps up the steering intensity the more you turn the wheel. In practice, this means the lock-to-lock ratio is very short, making it easy to link up tight corners.

It also makes it easy to navigate tighter driving scenarios, like parking, though it disguises how wide the turning circle is. Expect to do three-point turns fairly often.

For the suspension, the RS3 has adaptive dampers set-up that generally errs on the sportier and firm side. There is a ‘Comfort’ mode which irons out some bumps, but larger road imperfections still transmit harshly into the cabin.

It’s also worth noting at higher speeds there’s a considerable amount of road and tyre noise that comes into the cabin. Thankfully the Sonos sound system does a great job at drowning this out.

Lastly, the safety systems in this car are generally user-friendly, though the lane-keep assist can be a little too hands-on, especially on narrow roads with poor lane markings. Thankfully you can switch this off by pressing and holding a button on the end of the indicator stalk.

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.

Like all Audis, the RS3 is covered by a five-year, unlimited-kilometre warranty. There’s also five years of roadside assistance.

Logbook servicing is required every 12 months or 15,000km, whichever comes first.

You’re able to purchase a five-year pre-paid service package for $4010. That averages out to $802 per service, which seems like a lot until you see how much Mercedes-AMG charges to service an A45 S.

RS3 owners can also purchase two-year packages to extend the warranty, roadside assistance and servicing coverage. This allows new RS3 owners to have warranty coverage for up to nine years and it’s transferable to future owners.

This Audi has a three-year/unlimited km warranty. Service intervals are recommended every 12 months or 15,000 km, whichever comes first.
