Audi RS3 vs Audi S1

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.

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.

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 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 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.

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.

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.

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.
