2020 Audi A3 vs BMW 1 Series

What's the difference?

When the Audi A3 Sedan made its world entrance in 2013 it showed how a small car could be elegant, sporty and not a hatchback. The 40 TFSI S line plus looks almost like a last hurrah for the car before the next-gen A3 comes in 2020. You may want to wait for that if you’re concerned you’ll be driving a new car with the old look, or buy this one now and get good value for money. 

Comment call to action: Would you buy the current Audi A3 Sedan knowing that a new-gen one is just around the corner? Tell us what you think in the comments below.

To answer the question of whether it matters that the new 1 Series is no longer rear-wheel drive, I say no it doesn’t. It may not be as romantic on the absolute limit, but it is better in every measurable way, and still feels distinctly BMW despite moving to the conventional layout of its rivals. 

Be sure to check out Mal’s video review from the 1 Series launch last December:

The A3 sedan has barely changed its look since it arrived in 2013 but it has aged superbly with the help of a few updates over the years. I’m a fan of its proportions with the long bonnet, short boot deck and high waistline.

This special edition accentuates the sporty look more with larger 18-inch alloy wheels in a five twin-spoke design in contrasting grey, an S Line body kit including badged metal scuff plates and sports suspension which lowers the ride height by 15mm.

The A3 sedan's cabin has barely changed since its 2013 arrival. The only indication it's been around for so long is the small media screen which slides itself in and out of the dash, the rest of the interior is still modern and stylish. More than making up for that small screen is the 12.3-inch virtual instrument cluster that this special edition brings as standard.  

Leather upholstery is also standard and our car's was 'Rock Grey' in colour - a safer bet than white unless you plan on never eating or even just sitting in the car. 

The dimensions show the A3 Sedan to be 4458mm end-to-end, 1416mm tall and 1960mm wide (with the wing mirrors folded out).

Beware, this A3 could be the ‘old one’ soon. The new-generation A3 will make its debut in 2020 and will have a different look.

Yes, that kidney grille is rather large. If you want everyone to know you drive a BMW, you’ll love it. If not, get used to it. The X7, recent 7 Series update and upcoming 4 Series suggest they’re only going to get bigger. 

Nose aside, the 1 Series hatch has always had a distinctive, long-bonnet profile, which has generally been attributed to the rear-drive layout. Despite the move to a transverse engine, the new one is actually very close in proportions when compared side by side.

It’s just 5mm shorter in overall length and 13mm taller, with body width being the most notable change at 34mm wider. 

The key difference is that the front and rear wheels have been moved further back into the body, because of said engine layout change, and to make more back seat space in the rear.

Surprisingly for a model aimed at a younger demographic, the new 1 Series interior design isn’t quite the same step forward as the recent G20 3 Series.

It’s a cut above the X1 and X2 SUVS the new 1 Series shares its underpinnings with in terms of the shapes used, but is still classic understated BMW. 

However its headline act is the Live Cockpit driver display on both models, which gives you fully digital instrumentation and replaces traditional analogue gauges once and for all.

The answer is no, not very practical. Not for somebody my height with my life. I’m not being mean, it’s the truth. I’m 191cm tall and I can barely sit behind my driving position because legroom and headroom is that tight.

I have a four-year-old and it was hard enough fitting a top-tether car seat in there with the low ceiling let alone trying to strap him in which saw me kneeling in the gutter.

Room up front is better and while I don’t have a headroom issue it’s still a snug fit for me with my wingspan.

Cabin storage isn’t great with just two cupholders on board (in the front), while door pockets are small and so is the centre console storage bin.

The special edition does bring more in the way of utilities such as a wireless charging pad, and you’ll also find two 12-volt outlets (one up front and another in the back) and two USB ports (up front).

The A3 sedan’s boot is pretty decent in cargo capacity at 425 litres which is 85 litres more than the Sportback, but that hatch is more practical due to a larger boot opening and the load space offered with the rear seats folded.

With my modest 172 cm height, I never had any trouble with the old model, but the new 1 Series is a bit more more spacious by all the important measures.

The back seat base and backrest are a bit flat though, which is probably to help the backrest fold almost flat, but probably not very supportive during hard cornering.

There's also no centre armrest in the back or cup holders, but you do get bottle holders in the doors.

You also get two ISOFIX child seat mounts and there’s two USB-C charge points in the back of the centre console, but there's no directional air vents unless you opt for the dual-zone climate control that comes standard with the M135i. 

The boot has grown by 20-litres to a pretty impressive 380 litres VDA which includes a very useful cavity under the floor instead of a spare tyre. An inflation kit is there for those duties. With the back seat folded flat, boot space expands to 1200 litres VDA. 

For the F40 generation, the 1 Series range has been cut back to two variants from launch, with the 118i for volume sales and the M135i xDrive hot hatch taking aim at the new Mercedes A35 and the Audi S3. 

Both versions were priced $4000 higher than the equivalent models they replaced from launch, but have recently jumped a further $3000 and $4000 respectively. This puts the now-$45,990 118i beyond the starting prices for the equivalent Audi and Mercedes, and the $68,990 M135i xDrive is now nudging the A35’s list price.

The launch prices were largely offset by extra equipment over the previous generation, but the more recent hikes have taken the shine of this somewhat.

Thankfully, both 1 Series models now come standard with wireless Apple CarPlay. The previous ‘one year free, the rest you need to subscribe for’ plan has been scrapped since we shot the launch video below in favour of free CarPlay for life. There’s still no Android Auto, but this is due to change in July. 

The 118i packs more standard equipment than before in general, including the M Sport styling pack, head up display, wireless phone charger and adjustable ambient lighting.

The M135i adds bigger brakes, a rear spoiler and 19-inch wheels, plus sport seats with leather trim, and Harman/Kardon audio among a few other things.

You can get even more from the M135i with the $1900 M Performance Package, which drops the 0-100km/h claim by one tenth to 4.7s thanks to enabling engine overboost and lighter forged 18-inch alloys, which is signified by gloss black grille surrounds, intake elements in the front bumper, mirror caps and exhaust tips.

Other options include the $2900 Enhancement Package, which brings metallic paint and a panoramic glass roof. On the 118i, it also brings 19-inch black alloys. On the M135i, it also brings active cruise control with stop and go function. This package costs an extra $500 if Storm Bay metallic is chosen. 

The Comfort Package costs $2300 with the 118i and $923 with the M135i, and brings front seat heaters and lumbar adjustment for both front seats. On the 118i, it also brings proximity keys and electric front seat adjustment. On the M135i, it also brings a heated steering wheel.

The Convenience Package costs $1200 with either variant, and adds a powered hatch, modular storage system and cargo net and a ski port for the back seat.

The 118i can also be optioned with the $1000 Driver Assistance Package, which adds active cruise control (plus 0-60km/h AEB), adaptive LED headlights with auto high beams and a tyre pressure monitor.

Beyond the 118i’s standard M Sport pack, it can also be augmented with the $2100 M Sport Plus Package. This brings sports front seats, a rear spoiler, M-coloured seat belts, a sports steering wheel and upgraded M Sport brakes.

The A3 40 TFSI S line plus is a special edition but the engine hasn’t been given any extra grunt. Under that bonnet is a 2.0-litre turbo-petrol four-cylinder making 140kW/320Nm, shifting gears is a seven-speed dual-clutch automatic.

Both cars use versions of the three and four cylinder petrol engines from before, with the popularity of automatics leaving the previous manual option consigned to history.  The 118i’s 1.5-litre turbo three cylinder now produces 103kW/220Nm, with max torque available all the way from 1480-4200rpm. The 118i now uses the seven-speed dual clutch automatic transmission, as seen on Mini models that use the same engine. 

The M135i’s 2.0-litre turbo has been tweaked to take the place of the six-cylinder M140i from the last model and now produces 225kW/450Nm, with max torque available all the way from 1750-4500rpm. Its auto remains a torque converter though, but now the transverse-mounted unit also shared with Mini models with the same engine and splitting drive to all four wheels via the xDrive system for the first time. The drive split is constantly variable, but the rear bias tops out at 50 per cent and the only limited slip diff is an electric unit on the front axle.

According to Audi the A3 40 TFSI S line plus’s fuel economy is 5.8L/100km and that’s over a combination of urban and open roads driving.

My own testing saw a higher mileage. So, after 192km of motorways and daily commutes into the city I put in 18.8 litres of premium unleaded, which works out as 9.8L/100km.

Official combined fuel consumption is a decent 5.9L/100km with the 118i, but the M135i steps up to 7.5L/100km) 2.0 litre four in the m135i. Both engines require premium unleaded. 

Fuel tank sizes vary across the two models also, with the 118i measuring 42 litres and the M135i managing 50 litres, despite its need to package rear drive components somewhere under there also. 

This results in a decent theoretical range between fills of 711km for the 118i and 666km for the M135i. 

Leave any doubts that the A3 40 TFSI S line plus isn’t a real Audi at the door, please. This might be a bargain from a prestige point of view but the dynamic ability and driving experience are exceptional.

Yes, the steering is a bit light and numb, and sure the ride on those 225/40 R18 Dunlop SP Sport Maxx tyres with sports suspension frankly isn’t all that comfortable, but those of you looking for an engaging drive with pretty good acceleration (0-100km/h in 6.8 seconds) will be happy.

The Audi A3 40TFSI S line plus has comfortable supportive seats, good visibility and dimensions which make it the perfect little prestige limo for city parking and navigating through narrow lane ways.

For a brand with a marketing slogan of pure driving pleasure, this is the important part, particularly given the new 1 Series has lost its rear wheel drive USP. 

Why do some of us love rear wheel drive? It tends to be more fun when you're driving on the limit, and generally makes for nicer steering because you're only using the front wheels to turn corners.

So how does the new 1 Series drive? That depends on which version. 

The 118i is quite a nice package really. It rides a bit more gently than what I remember in the A-Class and generally feels more like a premium product. It also feels a step ahead of the 2 Series Active Tourer it shares its underpinnings with, which is a good thing.

The three-cylinder engine is quite smooth for a fundamentally unbalanced triple, and it makes enough power to get you out of trouble. 

Do you miss rear wheel drive? Not really, as you can only tell the difference when you're going real fast, which let's face it, is not somewhere 118i drivers are likely to go very often. 

The M135i is a vastly different beast, as you'd expect. Aside from being real quick, it's that much tighter everywhere, but still definitely on the more comfortable side than what we expect the future full house M version to be.

The continuously variable xDrive all-wheel drive system does a great job of putting its power down, but the rear bias maxes out at 50 per cent, which is probably spot on for chasing lap times, but means you miss out on the tailiness of the old one altogether. 

So it’s not as classically fun as the old M140i, but it’s easily faster, and that's what will probably matter most to most buyers. 

The new 1 Series comes with most of the important safety gear, but like the X1 and X2 SUVs and 2 Series Active Tourer that the new 1 Series shares its platform with, you still can’t get proper auto emergency braking unless you opt for active cruise control.

Both versions do offer partial automatic braking, which confusingly was enough to earn the new 1 Series a maximum five-star ANCAP safety rating according to 2019 standards, but we feel this is not good enough and is worth considering before you put your money down.

Aside from the options packages mentioned  above, active cruise control with AEB (up to 60km/h) can be added to either version for $850, but when it’s been a standard item on something as cheap as a Mazda2 since 2017, it’s not a good look. 

The A3 40 TFSI S line plus is covered by Audi’s three-year/unlimited kilometre warranty.

Servicing is recommended every 15,000km or 12 months which is the same coverage as rivals BMW and Benz but falling behind the duration of the mainstream industry.

A service plan is available – it’s a three-year/45,000km program and costs $1680.

The low score here is down to that short coverage. Come on Audi, make it five years.

BMW is yet to step up to the five year warranty offered by most mainstream brands and now Mercedes-Benz and Genesis, continuing with the three year/unlimited coverage matched by Audi. 

As always, BMW describes the service intervals as condition based, and the car will alert the driver when a service is due. This will occur at least every 12 months though, but individual intervals will vary based on how the car is driven. 

This can all be bundled into five year/80,000km service packs though, with the Basic pack costing $1465, but the Plus pack adds brake pad and disc replacement to regular fluids and consumables for $3790. Assuming 12 month intervals, these prices are about average for a premium branded product.
