BMW 1 Series vs Audi S1

What's the difference?

A brief dalliance with the 1 Series has left me impressed, if wanting to spend more time with it to get a better assessment of the day-to-day liveability of BMW’s entry-level model.

It’s a compelling offering if you’re after a premium small car, and even without the performance of the M135, the 118 is feature-packed.

Keeping pricing competitive should help the 1 Series buck the trend of buyers opting for small SUVs, but ultimately it’s just refreshing to see BMW putting effort into keeping a hatchback relevant (and up-to-date).

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

Cars this small shouldn't be this fast and useable at the same time, but the Audi S1 is. It isn't without its problems - the ride is harder even than the Fiesta ST which might weary some prospective buyers.

It's also a bit difficult to justify the price - in its basic form it's missing a few creature comforts that you'd expect in a $50,000 car - reversing camera, high-res screen, that sort of thing.

However, in the hot hatch world, those things don't matter. It has the bragging rights, the tech and the outright blinding speed to take on the bonkers Focus ST and equally zany Megane RS. And even the Audi S3.

The 1 Series has worn many faces over the generations and, like a lot of BMW designs that depart from tradition, this one might need to grow on some people.

That’s not to say there’s not a lot to like about the F70, but as BMW evolves its design language some changes might ruffle feathers - a lack of the iconic ‘angel eye’ headlight style being one.

But there’s still a kidney grille up front, with new design elements, plus those headlights that have a new vertical light signature are now sleeker than before, giving the new 1 a different ‘character’.

But from the rear, there are baby 3 Series Touring vibes, and it’s hard to find anything that might upset purists - there’s even the 'Hoffmeister kink' at the c-pillar. That’s the way the window angles back towards the front at the bottom.

Inside, the 1 Series has some proper sporty elements, even in the 118, that reference the M development that went into it.

There’s M-coloured stitching up over the dash fabric, for example, and illuminated aluminium panels with M-coloured lighting.

The steering wheel, wrapped in leather, is also an M feature, plus sporty seats are even present in the 118.

The interior is an overall cleaner look, in part thanks to the proliferation of features accessible by touchscreen, but BMW is refraining from going full ‘Tesla’ and removing all the buttons from the cabin.

The A1 is so small it starts to strain Audi's design language. When you cram on the S-style bumpers and raccoon-eyed trim on the hatchback, it's starts to look a bit busy.

It isn't quite a shrink-wrapped A3 - Ingolstadt's designers know better than that - but it's full of Audi design cues, such as the strong, light-catching character lines, distinctive LED daytime running lights and fondness for big wheels.

Inside is along the themes of the A3, with what are becoming Audi's trademark; round eyeball air-con vents, the manual fold-down screen familiar to Q3 owners (but smaller) and a good clear dash. The handbrake jars slightly as it feels cheap to hold and wobbles a bit.

The S Sport seats are big and comfortable, and the top half of the backs are capped in plastic, which was colour-coded on our car. The rear passengers will certainly get an eyeful of whatever terrifying hue you've chosen, so choose wisely.

Despite the five doors, the back seats are occasionals, like the Mini the A1 is gunning for, and the boot is very small, but okay for shopping for couples or singles.

Starting at $49,900, Audi S1 is by far the priciest of the small-hatch based hotties, at least until Mini's madcap JCW arrives. This price is just almost double that of VW stablemate's forthcoming 2015 Polo GTI.

Standard on the manual-and-five-door-only S1 is a ten speaker stereo, climate control, ambient lighting, remote central locking, cruise control, satnav, headlight washers, auto headlights with xenon low beams, partial leather seats, leather-bound steering wheel, auto wipers and rear parking sensors.

Our Misano Red ($990 option) came with two extra packs. The Quattro Exterior Package ($3990) adds bi-xenon headlights with red trim, red brake calipers, spoiler, quattro logos on rear doors (ahem!) and five-spoke 18-inch alloys that are part matt black, part polished.

The Quattro Interior Package ($2490) adds S Sport front seats with Nappa leather and red backrest capping with quattro logo (ugh), more nappa around the cabin with contrast stitching, flat bottom steering wheel and red rings on the air vents.

There's an S Performance Package that brings the best of these two packs together for $4990, saving about $1500 and the embarrassment of the quattro logos.

Our test car also had aluminium air vents ($220), black contrasting boot lid ($300) and black roof ($720).

The A1 is so small it starts to strain Audi's design language

The grand total is a sobering $58,610. There's a couple more options that'll easily pop you over $60,000.

Audi's MMI is dash-mounted in the A1 as there's no room on the narrow centre console. As ever, it works well and doesn't take much getting used to. The satnav is a bit grainy on the smaller screen but is otherwise a competent unit.

Sound is from a ten-speaker stereo and you can stream across Bluetooth or plug in a memory card. The sound was good but the system did take a while to find the phone whenever we came back to the car.

The two 1 Series variants have rather different running gear.

The 118 comes with a 1.5-litre three-cylinder turbo petrol engine that drives the front wheels via a seven-speed dual-clutch transmission (DCT).

It makes 115kW and 230Nm, and BMW says it’ll hit 100km/h in 8.5 seconds.

That’s in comparison to the beefier 2.0-litre four-cylinder unit in the M135, also turbocharged, but driving all four wheels via a similar seven-speed DCT.

It makes 233kW and 400Nm, and it’ll crack 100km/h in 4.9 seconds according to the Bavarian brand.

This is where the action is. The S1's tiny body packs a 2.0-litre turbocharged four-cylinder producing 170kW and 370Nm of torque. The S1 will streak to 100km/h in 5.9 seconds thank to the traction aid of quattro all-wheel drive.

All Audi S1s come with a six-speed manual

Despite a pretty solid hammering during its week with us, including more time than we'd have liked in Sydney traffic, the stop-start function helped deliver a pretty reasonable 10.2L/100km, however that's a long way over claimed 7.1L/100km.

All Audi S1s come with a six-speed manual, so dual-clutch haters can save the whining. The only downside from not having a self-shifter is the ECU can't deliver the boy racer farts, parps and crackles of the other S cars.

The launch drive for the 1 Series included some outer-suburban Melbourne traffic, a stint of highway driving down towards the Mornington Peninsula, and a semi-rural road loop for each variant before the return journey.

So, noting that we didn’t quite get the chance to really work out what it might be like to live with the 1 Series day-to-day, first impressions showed good signs.

Both variants still drive much like you’d expect from even a front-drive BMW, let alone the AWD M135, but the chassis and suspension seem like they’d be good counterparts on a daily drive.

In the M135, communication and compliance seemed well-balanced with each other for even some particularly rough surfaces, and after torrential rain there were some potholes that would properly upset most cars that didn’t faze the 1 Series too much.

The 118 seemed to let a little more road noise into the cabin, but that might have been a symptom of different road surfaces.

The steering is accurate, but the feel in both is a little heavier than needed, especially with the thick-rimmed BMW steering wheel that you’ll know about if you’ve driven anything from Munich in recent years.

It’s a very easy car to drive fast, especially with the combination of 233kW, 400Nm, and all-wheel drive at the M135’s disposal.

The chassis and tyres work quite well together to not only hold a corner at impressive speed, but also keep the car stable so that traction isn’t an issue when launching out.

There’s also the joy of hearing a turbo spool and flutter under load, which is hard to deny as a draw for petrolheads.

If you're buying the S1 as a comfortable urban runabout with a cool badge, you're half right. While the seating for front passengers is certainly supportive, the hard suspension tune will ensure you're well aware of road surface imperfections.

The S1 is a rocket

Thankfully, what it missed out on in the ride department it makes up for in every other way - the S1 is a rocket. The 2.0-litre turbo jammed under the bonnet has almost no lag and is paired with a slick six-speed manual that is terrific fun to manhandle through the gears.

The way the S1 picks up speed when it's on boost is addictive and licence-endangering. A flattened accelerator in second or third will obliterate just about anything this side of $100,000 and you'll be having more fun in this than big brother S3 because the chassis is more adjustable and there's a bit more life.

You can hear the turbo sing to accompany the bassy exhaust growl. Hit the massive brakes hard and the car remains stable even over rutted roads. Turning the wheel brings almost-instant turn-in, mashing the throttle again a fun little wriggle. It's superb.

It's tremendous fun point-to-point on a twisty road

You'll have to be a bit patient with the throttle to get the wriggle, though - give it too much too early and it will want to push wide, the quattro system shuffling power around to try and quell understeer while the electronic diff fiddles with the braking system to do the same thing. It gets there in the end, but you're better off meting out the power with your right foot for maximum rewards.

It's tremendous fun point-to-point on a twisty road - despite being a bit heavy for its size (1415kg), it's as chuckable as the next best thing, the Fiesta ST.

Six airbags, stability and traction control, ABS, brake assist and distribution all add up to a five star ANCAP rating.
