Audi RS3 vs Audi A4

What's the difference?

If conventionally powered cars really are on the endangered list, it’s vehicles like the Audi RS3 that will remind us what we’ve lost. There’s so much fun to be had in this car, that you really need to take it to a track to tap into it safely and responsibly. And there’s the rub.

While there’s no doubting the RS3’s potential, neither is there any doubt that the driveline absolutely dominates the experience. In fact, we reckon the S3 with its more modest (but still ample) performance and friendlier nature is probably the smarter car for the everyday. It’s also cheaper by about $20,000 and while it lacks the aggressive looks, it’s still a charming car. Perhaps all the more charming for its easier-going nature and balance of abilities.

So why buy the RS3? Because it’s the one that will keep you entertained for longer if you’re a serious enthusiast driver. But if you don’t plan to use the car for track days, there’s a strong argument that the RS3 is way more car than you’ll ever need. Of course, that sentiment never stopped performance-car lovers, did it?

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.

While the overall shape of the RS3 suggests evolution rather than revolution, the RS3 treatment has led to a much sportier look. We still reckon the sedan is the pick of the two body styles, mainly because it looks a bit more aggressive. Certainly, though, an aggressive look is not something either version backs away from, and those deep, wide blacked-out honeycomb grilles front and rear give the thing lots of presence.

So too do the blistered fenders, allowing for the extra track width that gives the RS3 its unique footprint. The front track itself is 30mm wider, but the wider fenders also gave Audi the chance to do some creative aero-management. Unlike, say, the Toyota Supra, for instance, with its faux vents up each side, the RS3’s lower-front vents and aero-slits behind each front fender are fully functional, directing air into the engine bay and away from the brakes respectively.

Another really neat function is the LED daytime running lights’ one-act play when you unlock the doors. As the car unlocks its doors, the LEDs spell out `R’, `S’ and `3’in sequence. Blink and you’ll miss it, but it’s a lovely touch that some manufacturers will never understand.

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.

Like the rest of the Audi A-series range, the RS3 is available in two body styles, a five-door hatchback and a four-door sedan. The five-door hatchback layout is the most practical of the two RS3 layouts, but both feature plenty of front-seat space and a rear seat that folds 40:20:40. 

Paddle shifters are mounted on the steering wheel rather than the column, so they move with the wheel. That can make it difficult to select the correct paddle in a hurry with lots of lock applied.

The Drive modes are operated by a switch low down on the centre-stack that is clearly designed for left-hand-drive cars. It’s too far from the driver and needs to be cycled through in one direction, rather than being able to select the next mode or the previous one.

Beyond that, the interior is a lesson to other car-makers on how to get an interior right. There’s a quality look and feel with the possible exception of the plastic trim below the passenger-side air-vents which looks and feels a bit cheap. There are plenty of cup-holders and cubbies around the cabin with two USB plugs in the front and two in the rear (for charging).

The RS3 loses some space compared to the regular A3 because of the performance hardware. Where the hatch can take 282 litres with all seats in place (1104L with second row stowed), the sedan can swallow 321 litres.

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. 

While the five-cylinder engine is more or less a carry-over from the previous RS3 model, the end result is still a pretty stunning one. With 2.5 litres of capacity, the turbocharged unit accounts for 294kW of power (the same as the previous model) and 500Nm of torque (up 20Nm).

The transmission is a seven-speed dual-clutch unit that is quite a familiar sight around Audi by now, and the all-wheel-drive system uses a centre differential with an electronic clutch-pack on each rear axle to give the car a Drift mode (although Audi insists you don’t refer to it in those terms) as well as torque vectoring with the ability to shift 100 per cent of rear-axle torque to the either wheel to maximise grip.

There’s now also an RS-specific exhaust system with an active flap to increase or tame exhaust noise according to which drive model is selected. The drive modes themselves stretch form Comfort to Auto to Dynamic, altering shift points, gear-shift aggression, throttle response and suspension firmness as well as that exhaust flap.

Brakes are enormous 375mm front rotors with six-piston calipers, that hardware forcing the fitment of a 19-inch alloy wheel (specific to the RS3) for brake clearance.

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.

Audi’s official combined fuel consumption figure for this car is 8.3 litres per 100km. Obviously, start using all that power and torque and that figure will grow significantly. Based on that, the car emits 190 grams of CO2 per kilometre, and with the 55-litre tank (which looks a bit small on paper) the range should still be around 600km between fill-ups.

The only catch with that is the high-tech nature of the engine means it requires the more expensive, Premium ULP at the bowser.

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.

First impressions are that this is a typical Audi in the way it fits together beautifully and is made from quality materials. The ergonomics – particularly the virtual cockpit - are spot on and it even smells like an Audi. Noise is well suppressed, the controls feel quality and the front seats are comfy. But from there, the overarching view is dominated by that powerhouse of an engine.

This isn’t just a quick car, it’s actually brutal in the way it builds boost almost immediately and then hurls the car down the road. To be honest, it’s almost too much, and the way the RS3 reels in the horizon will leave some drivers ignoring other sensory inputs in order to keep up with the car. Brutality breeds brutality, too, and the subsequent steering and braking inputs required when the throttle is pinned will not always be the considered, gentle type; they’ll often be gut reactions.

Thankfully, the rest of the driveline and platform has the smarts to make all this work. There’s awesome grip from the Quattro all-wheel-drive system and the car stays flat and steers in a fast, neutral but pin-sharp way. The dual-clutch transmission feels perfect for the engine, too, with ultra-quick shifts that become more aggressive as you ramp up the drive modes. Ride quality is good but we reckon there’s less bandwidth in the various drive mode settings than exists in the same system fitted to the S3 model we drove a few months ago. While the latter offered a broad range of suspension firmness, the RS3 seems to be a bit of a prisoner of its own performance, with Audi leaning all the drive modes towards a firmer setting in the name of body control.

That’s supported by Audi’s decision to offer us some race-tack laps in the RS3 to safely explore its high-end tendencies. At this point, the car emerges as a proper track-day proposition, all that power and control blending into a car that loves being thrown around a circuit. Perhaps the front seats could do with a little more side bolstering at track-cornering speeds, but overall, it’s clear that the RS3’s brief does, indeed, include a degree of race-track use.

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.
