Audi S3 vs BMW 2 Series

What's the difference?

There are plenty of historical instances where a particular model within a broader range manages to hit the absolute sweet spot even though it’s not the fastest or most expensive variant. Porsche’s GTS specification across various models is a great example of this.

And at the risk of being proven wrong when the all-new RS3 comes along later this year, this car, the S3, might just pull off that feat.

Yes, the new RS3 will be more powerful and will offer even more grip and sporty flavour, but it will also be more expensive. And we defy anybody to drive the S3 and say that it lacks dynamism in any single area.

It’s also a magnificently balanced car with the right amount of attention paid to every aspect of its trim and performance. That, in essence, is where that `balanced’ label originates and even though it’s felt most in the actual driving experience, it permeates throughout the entire vehicle.

The sleek 2 Series Gran Coupe has injected some life into the sedan segment and adds another dimension to BMW’s line-up.

After spending a week with the 118i hatch and another week with the 218i Gran Coupe, I would pick the hatch because it suits my needs better and has a more understated design, at least from the A-pillar back.

But there is little to fault in the 218i, aside from the obviously higher price compared with a mainstream sedan like a Mazda3. But, as with the hatch, if you want something a little more premium and a little more special, then this funky sedan is well worth considering.

Perhaps the most striking thing about the styling of the new Audi is just how similar it looks to the old model. Okay, this is not a new thing with Audi which has made a point of not throwing a handsome design into the dumpster in pursuit of new for new’s sake.

As such, the exterior lines are taut and typically Audi clean and, with the latest LED headlights and a refinement of the Audi trapezoidal grille, the look is fresh and crisp without being a novelty act.

Inside, the virtual dash display and large, relatively flat centre console almost amount to anti-styling. Or it would if the rest of the deal wasn’t so sharply angled towards a philosophy of less is more.

Again, this is classic modern-era Audi where the game is to make a complex layout look as simple as possible. The face-level air vents also seem to have borrowed a little Lamborghini (part of the Audi family) DNA.

I particularly like the new shift-by-wire gear selector which is a nifty looking switch but works just as intuitively as a conventional shift lever. New tech meets old muscle memory, I’m calling it.

It's worth mentioning (again) just how good Audi’s customisable dashboard display is. With sharp, clear graphics and the ability for the driver to prioritise the information on display at the time, the S3’s display is still about the best in the business.

Overall, ergonomics have always been a long-suit of this brand and there’s been a clear intention to follow that tradition this time around.

From the front, the 2 Series Gran Coupe carries the same face as the handsome 1 Series hatchback. But from the A-pillar back, it’s a completely different look. 

BMW’s ‘Gran Coupe’ series of models - 2, 4 and 8 Series - are not just regular sedans. They are sleeker, with a coupe-like sloping roofline and a more squat stance. It’s BMW’s way of making sedans sexy. And it has worked on each of those models.

The 218i’s boot sits up high and the rear treatment with the wide slimline tail-lights and integrated boot lip spoiler make the car visually appealing. I prefer the look of the 1 Series hatch, but appreciate the sleek sedan.

As with the hatch, the 218i’s interior is a modern take on the unmistakable BMW cabin, and for the most part it’s a successful design.

While SUV owners are often quick to tell you that they bought their car for its interior space, the truth is sometimes different. And without the huge wheel-wells and suspension towers of a high-riding SUV, the conventional hatch or sedan often has an advantage.

Certainly, there’s no lack of room in the S3 and the hatchback version has a wide hatch opening to make loading easier. The sedan, however, is a full 150mm longer than the hatch and that extra is all behind the rear seat.

So the boot is actually very useable with a capacity of 325 litres. Audi claims the same 325 litres for the Sportback, but that figure jumps to 1145 litres with the rear seat folded flat.

The rear seat in either variant is handily split 40/20/40 and there are storage nets on the back of each front seat, luggage nets in the cargo area and 12-volt outlets in both the centre-rear and luggage compartment. Even floor mats are standard.

The main key difference between the 1 and 2 Series is the boot capacity. But in terms of interior appointments, not much separates the two.

Our 218i test car was optioned with black ‘Dakota’ leather trim, which does not look or feel particularly premium. The blue pattern trim in the 118i hatch was much more visually appealing, helping to break up the dark greys of the cabin. But in the 218i, it just makes everything look rather dark and gloomy.

As with the 118i, the BMW 'iDrive' controller and multimedia touchscreen are top notch, all controls come to hand easily, and the dash is angled to the driver. For more details on the interior, check out my 118i review.

The bigger differences are in the second row. The Gran Coupe has less headroom compared with the hatch, due to the sloping roofline and the optional sunroof.

Both body styles share the same 2670mm wheelbase, which should mean legroom is the same. For some reason the 218i feels ever so slightly tighter in the rear, but we are splitting hairs here.

Rear-seat occupants have access to two USB-C ports, map pockets and, unlike the hatchback, the Gran Coupe has a central fold-down armrest with two cupholders. Tall bottles will fit in the door storage compartment. Sadly the 218i lacks any rear air vents.

The doors also have a smaller aperture, so it’s not as easy to get in and out of compared to the hatch.

The rear seats fold 60/40 via levers in boot. Speaking of which, the boot can swallow 430 litres of cargo, which easily exceeds the 380L capacity of the 118i hatch. It also matches the boot space in the Mercedes-Benz A180 sedan and is just five litres bigger than the Audi A3 35 TFSI sedan.

Determining whether the BMW 218i Gran Coupe represents good value is tricky. Because you can get any number of small sedans from mainstream brands - like the Mazda3, Toyota Corolla, Subaru Impreza and more - for much less money, but with similar, or in some cases, more kit.

But if you’ve been 'glamoured' by the BMW badge and couldn’t possibly buy something non-European, the good news is the Bavarian brand is much better at including standard features than it used to be.

Could there be more standard gear for the price in this car? Absolutely. But, it’s not a slim features list either.

The 218i kicks off the 2 Series Gran Coupe line-up from $56,900, before on-road costs. From there you can step up into the 220i ($59,900) which gets a little more power and torque, and then there’s the sporty M235i xDrive Gran Coupe in Pure ($74,900) and regular guise ($79,900).

The price difference between the 218i sedan and the 118i hatchback I reviewed recently, is $7000. That is a massive uptick in price for a vehicle that, underneath, is identical. Essentially you’re paying for the boot.

It’s especially surprising when you consider the price gap between the hatch and sedan versions of its chief rival - the Mercedes-Benz A-Class A180 - is just $1700. While the Audi A3 35 TFSI sedan is only $2500 more than the Sportback hatch.

A lot of mainstream brands don’t charge any extra for a sedan body style over the hatch model in the small segment. Take a bow Mazda3, Kia Cerato and Toyota Corolla.

Here’s where a lot of the extra currency demanded for the S3 goes. Forget the 1.5-litre engine in the base-model A3, and instead move to the two-litre four-cylinder as seen in the A4 40 TFSI. Then, add extra turbo-boost (up to 1.8 bar thanks to an efficient intercooler) different variable valve timing protocols, and a direct fuel-injection system with a specific calibration and the potential to create injector pressures of up to 350 bar, and you have the S3’s powerplant.

Maximum power is 228kW at anywhere from 5450 to 6500rpm, and maximum torque of 400Nm produced in a broad range between 2000 and 5450rpm.

Transmission is a seven-speed dual-clutch unit driving through all four wheels as per Audi’s Quattro mantra, although it’s important to note this version of Quattro is the simpler, arguably less pure, on-demand system where the car behaves as a front-drive platform until the all-wheel-drive system is required to step in.

That said, with 228kW under its wheels, that’s a fair bit of the time. And compared with previous systems, this one takes more notice of driver inputs and wheel-speed to be less reactive and more active.

Mirroring the 118i, the 218i uses BMW’s three-cylinder turbocharged petrol engine, with power and torque outputs of 103kW and 220Nm, respectively. This compares to 110kW/250Nm for the base Audi A3 and 100kW/200Nm for the Mercedes-Benz A-Class.

The 218i uses a seven-speed dual-clutch automatic transmission driving the front wheels only.

According to BMW, the 218i can complete the 0-100km/h dash in 8.7 seconds - 0.2sec slower than the hatch.

Audi quotes an official combined cycle fuel consumption figure of 7.4L/100km for the A3 Sportback and 7.3 litres for the sedan.

That difference is a bit of a mystery given the sedan is heavier (by just five kilograms) until you consider that the combined figure includes freeway running, at which point the sedan’s extra 150mm of length and different rear diffuser may be the aerodynamic deal-breaker.

The Sportback emits 170 grams of CO2 per kilometre (166 for the sedan) and with the 55-litre tank fitted, both variants should have a range of around 750km between fill-ups.

On the official combined fuel cycle, the 218i uses 5.9 litres of fuel per 100 kilometres - the same as the 118i hatch. After a week of mixed driving, I recorded a figure of 9.1L/100km, which is quite a bit more than that official figure.

In terms of CO2 the official emissions figure is 135g/km and the 218i requires 95 RON premium fuel for its 50-litre fuel tank.

Some cars take a few minutes at the wheel before they start to get chatty. Not so the S3. From the moment you grab the lovely leather tiller, haul it into gear and give the perky little turbo-motor a squeeze on the throttle, the Audi is making all the right noises and giving clear, precise feedback on its every move.

Sometimes, cars with lots of tyre, lots of all-wheel drive grip and the sort of sharp steering fitted here, can start to feed back so many responses that it becomes difficult to know which one to respond to.

Not the S3, which seems tuned to a keener driver’s priorities (as it should be, of course). As a result, the steering feedback is distinct from what the rest of the front end is doing and everything else going on is clear, quantifiable and designed to improve the experience.

That even extends to the soundtrack which, Audi told us does not use any electronics to improve it beyond amplifying the engine-bay harmonics which use the windscreen and scuttle as their 'speaker.'

Combined with the active exhaust system, this car honestly sounds like a five-cylinder engine (I opened the bonnet to count the spark plugs to make sure it wasn’t. It isn’t.)

If you’ve ever driven a five-cylinder Audi or a V10-powered R8 (two in-line fives, really) the tune will be a familiar one. Lovely, and – again - such amazing attention to detail.

The 2.0-litre engine runs fairly high boost levels, but that doesn’t seem to have affected the way it storms off the mark. Neither does the dual-clutch transmission contribute any delay, provided you haven’t managed to stand on the brake and throttle at the same time (as many left-foot brakers might).

At that point, the driveline goes into sulk mode and will force you to wait a heartbeat or two before full power is restored. This can be an issue when trying to dart across a busy intersection or merge into a traffic flow.

It’s not a new thing to Audis, but remains an annoyance to those of us who equate having two pedals with having two feet.

The driver-selectable drive modes fitted to the S3 are interesting inasmuch as they actually make a meaningful difference to the way the car operates. They alter the transmission shift points, the throttle sensitivity, steering weight and damper settings.

'Comfort' mode will be the default for most owners, and while 'Dynamic' does sharpen up the dampers ever-so-slightly beyond an acceptable day-to-day level of firmness, it also adds weight to the steering feedback.

Frankly, I don’t think it needs it and simply adding resistance feels like a token gesture. And since the steering has a (non-negotiable) variable rate in the first place, bigger inputs equal a bigger proportionate change of direction anyway.

The damping control is now the more sophisticated magnetic-hydraulic type where hydraulic pressure varies the valving rather than the simpler, previous system of energising an electro-magnet to alter the viscosity of the damping fluid.

This more finite control system has allowed more 'bandwidth' as Audi puts it, between Comfort and Dynamic damper settings.

While the auto mode is almost prescient, it’s not actually pre-emptive but rather takes into account suspension deflection, wheel-speed and driver inputs to come up with a combination of settings to make the most of the situation.

And if you really want to fiddle, you can choose 'Individual' and create an overall setting that combines bits of Comfort and Dynamic with a smattering of 'Efficiency' thrown in.

Toggle down to Dynamic and throw the S3 at some bends and it soon emerges as a pretty gripped-up piece of equipment. The front-drive bias is not really noticeable, but then neither is the transition where the computer begins to engage the rear multi-plate clutch to turn the rear axle into an active participant.

There’s certainly no lack of grip at any stage of a typical corner, and even the odd unexpected damp patch poses no awkward questions. Perhaps the biggest grumble would be the tyre roar at highway speeds, but that’s often the price of performance rubber.

If you love the look of the 2 Series Gran Coupe but are after an extra dollop of performance, the all-wheel drive 225kW/450Nm M235i xDrive is the pick of the range.

But don’t think the 218i is a lazy performer - it’s far from it.

The 218i’s acceleration is responsive, even quick, and it offers more than enough straight-line performance to satisfy most drivers. 

On take-off there is some turbo lag, which isn’t helped by the fuel-saving idle-stop system, however that can be switched off, which we did every time we got behind the wheel.

Momentum was a little blunted by a steep hill, but other than that, no complaints about the sweet engine.

Steering is weighted on the heavier side but it is sharp.

As is expected of a BMW sedan, the 218i is engineered for engaging handling, and the balanced chassis and well-tuned suspension set-up encourage enthusiastic driving.  

Excellent road-holding and grip ensured it did not come unstuck on uneven roads and overall the 218i feels really solid. Those front-wheel drive naysayers have officially been put in their place!

'Sport' mode livens things up with a noticeable improvement to throttle response.

The ride seems more supple at speed, but can feel on the firmer side in urban driving. But nothing that would strike it from your shopping list.

The 2 Series Gran Coupe carries over the maximum five-star ANCAP crash safety rating awarded to the mechanically related 1 Series hatch. The test was conducted in 2019.

Standard safety equipment includes low-speed auto emergency braking, forward collision warning, lane departure warning, rear cross-traffic alert, driver attention alert, front and rear parking sensors, reversing camera, cruise control, and six airbags - although it doesn’t include a front centre airbag.

Audi has finally had to cave in and extend its warranty to match its competition. So, any new Audi sold after January 1 this year moves up to a five-year/unlimited kilometre factory warranty; a big step up from the previous three years of cover.

S3 buyers can also opt for Audi’s five-year service plan which costs $2580. Servicing is set down for every 15,000km or 12 months.

The 218i comes with BMW’s three-year/unlimited kilometre warranty - a term that is well behind the majority of its competitors that offer five-year/unlimited kilometre cover. 

Rather than an annual service schedule, BMW uses ‘condition-based servicing’, which essentially means that the vehicle’s computer will inform you when the car needs a service.

BMW’s 'Service Inclusive' pre-paid plan covers owners for five years or 80,000km for the 2 Series, and involves a $1700 up-front payment. It averages out to $340 per service, which is actually pretty reasonable for a high-end brand.
