Audi RS3 2018 review: Sportback
It's a case of the fast and the furiously uncomfortable with Audi's RS3 Sportback. But a firm ride is probably a fair price to pay for a 300kW hatch-shaped missile, right?

In the late '70s the Mk1 Volkswagen Golf GTI was the original hot hatch, combining light weight with a snappy engine, taut suspension and racy looks to capture the imagination of a generation of enthusiast drivers.
Fast-forward more than four decades and the hot hatch has gone incandescent courtesy of the new, second-generation Mercedes-AMG A 45 S, which we'll see in Australia in early 2020, with a likely price tag in the low $80k bracket.
The first featherweight GTI boasted a power-to-weight ratio of exactly 100kW/tonne. The new AMG A 45 S is nearly twice the weight, but packs close to four times the punch, so bingo, power to weight is no less than 201kW/tonne.
We drove the new compact powerhouse on road and track at its global media launch to see just how much the hot hatch times have changed.

|Engine Type||2.0L turbo|
|Fuel Type||Premium Unleaded Petrol|
So, let's take a quick tour around the outside, which is visually a pumped-up version of the Merc A-Class hatch. There's the now AMG signature 'Panamericana' grille with 12 vertical louvres, a wing-like front spoiler treatment, extra aero bits (including spoilers at top of front air intakes), and 'Power Dome' bumps in the bonnet. The side skirts are wider, and 19-inch twin five-spoke rims are standard.
At the back there's an aggressive diffuser, side spoiler lips on the rear apron, fat 90mm quad exhaust pipes, and a lip spoiler on the roof.
The interior is another case of the A-Class on 'roids. A combination of Merc's 'Artico' faux leather and 'Dinamica' microfibre trim is accented with racy yellow highlights, with a nappa leather and Dinamica AMG Performance wheel and sports pedals completing the picture.
And the twin widescreen 'MBUX' instrument and media display boasts AMG-specific read-outs on everything from gear selection, warm-up menu, car set-up, a G-metre, race timer and engine data. The standard 'Track Pack' even includes specific circuit layouts and data.
At just under 4.5m long, a bit over 1.8m wide, and fraction over 1.4m tall the A 45 S in the dimensional bullseye for a compact hatch.
The A 45 S driver is presented with the same sleek 'MBUX' widescreen display found in the Mercedes-Benz A-Class, and storage runs to two cupholders in the centre console, a lidded bin/armrest between the seats (including twin USB ports), decent door pockets with room for bottles and a medium-size glove box.
In a swap to the rear, sitting behind the driver's seat set to my (183cm) position, I enjoyed adequate knee and foot room, although headroom isn't as generous.
A centre fold-down armrest incorporates two cupholders, again there are generous pockets in the doors with room for bottles, and adjustable ventilation outlets are set into the back of the front centre console is a welcome inclusion. No map pockets on the racy, hard shell sports front seats, though.
There are three belted positions across the rear, but the adults using them for anything other than short journeys will have to be good friends and flexible. Best for two grown-ups, and three kids will be fine.
Boot volume is a reasonable 370 litres (VDA), expanding to 1210 litres with the 40/20/40 split-folding rear seat down. There are tie-down hooks, a 12-volt outlet and elasticised storage pockets either side of the load space to further enhance useability. But beware, the Merc-AMG A 45 S is a no-tow zone.
The new A 45 is launching in the premium S variant only (a 'base' non-S version is offered in other markets). The outgoing model was tagged at $78,611, before on-road costs, prior to its discontinuation in January this year, and Mercedes-Benz Australia has hinted strongly that a price increase is likely. So, expect a list price in the low $80k range.
We'll cover active and passive safety tech in the safety section, and although final Australian specification is yet to be confirmed you can expect the standard features list to include the 19-inch alloys, 'Artico' faux leather and 'Dinamica' microfibre trim upholstery, the 'MBUX' widescreen cockpit display (two 10.25-inch digital screens) and 'MercedesMe' voice recognition, heated and electrically-adjustable sports front seats, auto adaptive LED headlights, LED tail-lights and DRLs, keyless entry and start, auto-dimming rear-view mirror, dual-zone climate-control, sat-nav, multi-function sports steering wheel, active cruise control, rain-sensing wipers, Active Parking Assist' (with ultrasonic proximity sensors front and rear), rear privacy glass, plus premium audio with digital radio, as well as Apple CarPlay and Android Auto.
The A 45 S's all-new 2.0-litre (M139) engine is claimed to be the most powerful series production turbo four ever made, pumping out 310kW at 6750rpm and a monumental 500Nm, peaking between 5000-5250rpm. That's up from an already impressive 280kW/470Nm on the out-going model.
It's an all-alloy, closed deck design fed by a combined direct and port fuel-injection system, with a single, twin-scroll turbo featuring low-friction roller bearings for quick spool up.
It's transversely mounted, but compared to the previous model has been spun 180-degrees on its vertical axis so the turbo's near the firewall and the intake system sits at the front to simplify and shorten ducting on the intake and exhaust sides.
The cylinder linings are treated with Merc's patented 'Nanoslide' coating, which delivers an ultra-hard, mirror-like surface for less friction and greater durability. And 'Camtronic' variable valve control sits on the exhaust side.
Claimed fuel economy to the combined cycle NEDC (New European Driving Cycle) standard is 8.3L/100km, the engine emitting 189g/km of CO2 in the process. Figures for the Australian (ADR 81/02) standard will be issued at the time of the car's local launch in early 2020.
Stop-start is standard, minimum fuel requirement is 98 RON premium unleaded, and you'll need 51 litres of it to fill the tank.
Our combination of furious hot-lapping on the circuit and relatively enthusiastic open road driving on the launch program means we'll wait until we test the car on home soil to log a real world average.
Mercedes-AMG invited us to the Jarama race circuit just outside Madrid in Central Spain, and the twisting B-roads nearby, to sample its latest pride and joy.
In the AMG tradition the engine is assembled by hand, by one technician. And hats off to the spanner twirlers, they do a great job. It's a spectacular unit. Torque delivery is shaped to mimic a naturally aspirated engine, with the maximum figure arriving between 5000-5250rpm.
But that's not to say it's hollow in the mid-range. Around 90 per cent of that peak number is available from below 3000rpm and low-end throttle response is brilliantly crisp and linear, helped in no small part by roller bearings on the turbo for a quicker spool up.
Merc-AMG claims 3.9 seconds for the sprint from 0-100km/h, which is supercar fast and with drive going to all four wheels entertainment is the name of the game.
The eight-speed dual-clutch auto is positive and sharp, especially in manual mode where shifts flick through in much less than the blink of an eye.
And as the A 45 S beefs up the A-Class on the outside, it's the same underneath the skin with body reinforcement including an alloy sheering plate under the engine, a front strut tower brace, extra reinforcement between side members and A-pillars, and diagonal struts on the front and rear of the underbody.
So, the strut front, four-link rear suspension has an extra stiff platform to hang from, and the three-mode 'Ride Control' active damping can transform the ride from soft and compliant to tightly buttoned down.
The speed-sensitive, electromechanical steering is specifically tuned for this car, and it points accurately with good road feel and pleasantly firm weight in Sport and Sport+ modes.
Rubber is Michelin Pilot Sport 4 S, and it grips hard. On the fast and technical Jarama circuit they performed flawlessly, helping the A 45 S transform its prodigious power into maximum forward velocity without fuss.
The icing on the dynamic cake is 'AMG Dynamic Select' with six modes from 'Comfort' to 'Race' adjusting the engine, transmission, steering, suspension, and exhaust.
On top of that 'AMG Dynamics' uses the ESP and torque vectoring (by braking) to vary the level of stability and slip through four levels from 'Basic' up to 'Master'.
We played with all the toys including 'Race Start' and a 'Drift Mode' made possible by a new rear axle featuring two multi-disc clutches - one for each rear wheel.
Torque is split variably between front and rear axles with a default setting of 50/50 rising to around 70 per cent to the rear when pushing hard. Drive is also continuously managed across the rear axle, and like a swan gliding across the lake all the action happens seamlessly out of sight, turning you into a track hero in the process.
The first-gen A 45's exhaust was a mass of pops, bangs and crackles, while this car's more rasping and rorty exhaust note is controlled by a flap in the system adjusted by engine speed and load. It's also amplified by the 'AMG Real Performance Sound' system, which puts some actual engine and exhaust noise (nothing is synthesised) through the speakers.
Open road ride comfort in the softest setting is surprisingly good, with rough surfaces unsettling the car only slightly despite the big 19s and high-performance rubber. Body control is S and S+ settings is spot-on, the car feeling planted, predictable and ultra-responsive on tight, twisting backroads.
Braking power is professional grade with six-piston calipers at the front and single piston rear, on vented and perforated rotors all around. Even following session after session on the track there wasn't a hint of fade.
5 years / unlimited km warranty
Although final Australian spec is yet to be finalised, you can expect a host of active safety tech including ABS, BA, EBD, stability and traction controls, a reversing camera (with dynamic guidelines), 'Active Brake Assist' (Merc-speak fo AEB), 'Adaptive Brake', 'Attention Assist', 'Blind Spot Assist', 'Cross-wind Assist', 'Lane Keep Assist', a tyre pressure warning system, the 'Pre-Safe' accident anticipatory system, 'Traffic Sign Assist' and 'Adaptive High beam Assist'.
If all that fails to prevent an impact you'll be protected by nine airbags (front, pelvis and window for driver and front passenger, side airbags for rear seat occupants and a driver's knee bag), and the 'Active Bonnet' automatically tilts to minimise pedestrian injuries. A first-aid kit and hi-vis vests in the boot are thoughtful additions.
The A-Class was awarded a maximum five ANCAP stars in 2018, and for smaller occupants there are three child restraint/baby capsule top tether points across the back seat, with ISOFIX anchors on the two outer positions.
The Mercedes-AMG range is covered by a three year/unlimited km warranty, which, like Audi and BMW lags behind the mainstream market where the majority of players are now at five years/unlimited km, with some at seven years.
On the upside, Mercedes-Benz Road Care assistance is included in the deal for three years.
Service is likely to be scheduled (as per the out-going A 45) for 12 months/20,000km (whichever comes first) with pricing available on an 'Up-front' or 'Pay-as-you-go' basis.
For the first-gen A 45 pre-payment delivers a $500 saving with the first three services set at a total of $2950, compared to $3650 PAYG. Fourth and fifth services are also available for pre-purchase.
Hot hatches are often referred to as firecrackers, but this Mercedes-AMG A 45 S is more like a fully-lit Exocet missile. It's massive fun, and hugely capable, and those ready to stump up the bucks should be rubbing their hands together. Very good things come in this compact package.
