BMW M4 VS Audi RS5
- Adaptive suspension
- Ripping dual-clutch auto
- No AEB
- Awkward access to tight rear seats
- So-so warranty
- Tight rear headroom
- Misses V8 growl
- Rear entry/egress
When it comes to cars, the letters B, M, and W carry huge credibility. But the extra letters and numbers that follow make all the difference.
A second M for example, means the hot rodders in the Munich maker's performance and racing skunkworks have played with everything from the drivetrain, aero and suspension, to the rims, rubber and interior design.
The number sitting next to it then determines whether you're looking at a compact firecracker (M2), fast-lane monster (M5), or bruising family truckster (X6 M). But every now and then some additional letters find their way onto even a BMW M car's bootlid.
In this case, a C and an S are significant additions to the already impressive M4 badge. They stand for Coupe Sport and were famously applied to BMW's achingly beautiful (E9) coupes of the late 1960s and early '70s.
So, with the howling echo of that all-time classic's in-line six ringing in its ears, the new M4 CS stands up as a proper high-performance coupe, pitched against the likes of Audi's recently reborn RS 5, the Lexus RC F, and Merc-AMG's soon-to-arrive C 63 S Coupe.

This car has some seriously big shoes to fill - think Ian Thorpe size, but bigger. It’s Audi’s new, second-generation RS 5 Coupe, the Bavarian maker’s mid-size performance flagship, sitting above the S5, and on paper it’s a clear step ahead of the model it replaces.
It’s powered by a 2.9-litre, twin-turbo V6 pumping out enough kilowatts to power a small town, and features a new eight-speed Tiptronic auto, sending drive to all four wheels via Audi’s latest generation quattro system.
Sitting on the VW Group’s MLBevo platform, it’s around 60kg lighter, and more fuel-efficient, yet able to blast from 0-100km/h in less than four seconds.
The thing is, the last RS 5 had something this new rocket ship doesn’t; a superbly sonorous, 4.2-litre, naturally aspirated V8 sitting in its nose.
I straight-up loved the out-going RS 5, bonding with it over thousands of kilometres here and overseas. Up and down Europe’s most challenging alpine passes, and in a previous life, knocking over a story where we drove through eight European countries in a single day.
This new RS 5 produces the same number of kilowatts as the old atmo hero, but adds roughly 30 per cent more torque. The question is, can it match or better its older counterpart on that most intangible parameter – charisma?

The BMW M4 CS is every bit as fast and engaging as you'd expect it to be. But be prepared for the day-to-day compromises that go with its pared back interior layout. It's beautifully engineered and dynamically excellent, but will have its hands full when Merc-AMG's similarly sized and priced (updated) C 63 S Coupe arrives shortly to rattle its cage.
Is the BMW M4 CS your kind of four-seat sledgehammer? Tell us what you think in the comments section below.
BMW offers the 'Service Inclusive' program, a one-off advance payment to cover scheduled costs at the 'Basic' or 'Plus' level.
While it may not sound as good as the outgoing model, the new RS 5 is blindingly fast, outstanding dynamically and loaded to the gunwales with standard features and tech.
A step ahead on paper, and in reality. It’s a brilliant, and yes, a brilliantly charismatic package.
Has Audi done enough with the new RS 5 Coupe to out-gun its primo performance coupe competitors? Tell us what you think in the comments below.
The M4 in either entry-level Pure, or next-step-up Competition spec already looks like John Cena in a 10-year-old's t-shirt, with muscular bumps, curves and cuts extending aggressively in all directions. From its bulbous 'power dome' bonnet, to the pumped-up guards and gaping vents, the M4 screams 'don't argue'.
But this CS version borrows heavily from the track-focused M4 GTS (phased out earlier this year) and dials the aggro up a few notches.
A Matterhorn-sized bulge in the centre of the lightweight CFRP (Carbon-Fibre Reinforced Plastic) bonnet descends towards a broad air extraction vent that could double as a stormwater drain in bad weather.
The front, exposed carbon splitter is a slightly less accentuated version of the GTS's race-ready set-up, and the signature kidney grille is finished in menacing gloss black.
That black finish, part of the standard BMW Individual 'Shadow Line' package, also extends to the side-window trim, window recess covers, and vents on the front wings.
CFRP (unpainted this time) reappears on the roof, and an exposed carbon Gurney flap-style spoiler adds a touch of flash and aero efficiency to the bootlid. A nice match for the carbon diffuser below.
Suitably wide black alloy rims (19-inch front, 20-inch rear) further enhance the intimidating look, with twin LED headlights and an 'Organic rear lighting system', the latter another lift from the GTS, delivering an impressively vivid display.
The interior is familiar BMW territory, but it does feel like you've had a nasty break-up and your significant other has filled the moving van with all the luxury bits.
The leather and Alcantara trimmed sports seats are classy and racy enough, but the door cards are made from a natural-fibre composite BMW calls 'Nawaro'. There are no storage pockets, and you get a webbing strap to help pull the door closed.
Super lo-fi, and bafflingly, the 'armrest' slopes downward at an angle that, despite an Alcantara-trimmed pad, makes it just about impossible to actually rest your arm on it. Perhaps it adds some wheel-twirling elbow room, but for the other 99 per cent of the time it's just annoying.
Although trimmed in contrast-stitched Alcantara, the centre console is also a rudimentary affair, with no storage box between the front seats or adjustable air vents for rear-seat passengers. It might be good for weight saving, but it's not so great in terms of day-to-day practicality (which we'll get to shortly).
There's more Alcantara on the M Sport steering wheel (a leather wheel is a no-cost option) and dash-panel insert, with the CS designation neatly called out in mosaic-style lettering near the centre stack.
In developing the look of this car, Audi says its design team took inspiration from the ultra-wide-body Audi 90 IMSA GTO racer from the late ‘80s, driven to glory in the USA by the legendary likes of Hans-Joachim Stuck and Walter Rohrl.
The RS 5’s cool, confident stance is the result, with the blistered guards, the detail vents clustered with the head and tail-lights, as well as other aero pieces echoing that track weapon.
At just over 4.7 metres long, the new RS 5 is 74mm longer (there’s an extra 15mm in the wheelbase), and a single millimetre wider than the previous RS 5, but it’s still a full 15mm broader across the beam than the current A5 Coupe. The new car also wears a flatter, honeycomb version of the brand’s signature ‘Singleframe’ grille, and sits on bold 20-inch rims.
The interior is luxurious, suitably racy, and black. The multi-adjustable RS sports front seats are trimmed in nappa leather with contrast stitching and quilting on the centre panels.
A typically broad centre console is highlighted by brushed-metal elements with flashes of carbon dialling up the premium look and feel.
The slick, 12.3-inch ‘Virtual Cockpit’ display dominates the view straight ahead, allowing you to switch between screens depending on the mood you’re in and what you want to get up to. While the 8.3-inch hi-res colour ‘MMI touch’ display sits proud of the centre dashtop.
It's a subjective call, but I’m a big fan (no pun intended) of Audi’s approach to the front ventilation outlets, framed within a narrow, chrome-edged band, sweeping confidently across the dash.
When it comes to cars, practicality is a subjective area. The M4 CS offers plenty of space for the driver and front-seat passenger, with room for two more in the back, as well as a decent boot. Practical, right?
But day-to-day details make all the difference and the drive to simplify the CS's cabin and reduce the car's overall weight has seen many common interior-storage options deleted.
The price CS owners pay for racy minimalism is a complete absence of door bins, no lidded box between the front seats, and no oddments tray in the middle of the centre console. Just a pair of cupholders ahead of the gearshift, and a shallow tray beyond that.
If you and a friend get into the car each carrying a standard load of personal junk like a phone, keys, wallet, and a beverage of some description, capacity is immediately exceeded.
Yes, you can shove all that 'stuff' into the (medium-sized) glove box, and that's probably the safer option anyway. But it's not as convenient as slipping things into strategically placed bins and boxes.
In terms of charging/connectivity there's a 12-volt outlet between the cupholders, and a single USB port oddly placed towards the rear of the centre console.
And while there are two seats in the back, getting to them requires the flexibility of a side-show contortionist, and the patience of a Tesla Model 3 reservation holder (the electric system that slides the front seat forward is glacially slow).
Even once you've managed to thread the needle through to the back, headroom is tight, so it's fine for kids and an occasional-only option for grown-ups. There are no cupholders or even a fold-down centre armrest back there, but there is a small, open oddments tray between the seats.
A cargo net is standard, there are four tie-down anchors, a small netted storage section behind the passenger side wheel tub, a cubby on the opposite side, shopping-bag hooks and conveniently placed handles, which release the 60/40 split-folding rear seat backs to liberate more room.
Don't bother looking for a spare wheel of any description. A repair/inflator kit is your only option.
The RS 5 is a classic 2+2, providing generous space for the driver and front seat passenger, with those consigned to the rear still enjoying comfy accommodation, including adjustable ventilation control (with digital display), but tight headroom courtesy of the tapered coupe roofline.
Getting into the back is a moderate struggle, but once behind the driver’s seat, set for my 185cm frame, there’s surprisingly good legroom and decent space for your feet, but sitting fully upright meant twisting my head to an angle that would have any chiropractor rubbing their hands with glee.
Cabin storage runs to a lidded bin between the front seats (with additional space in front), an average size glove box, front-door pockets able to hold standard water bottles, netted map pockets on the front seatbacks, and oddments trays in the rear.
The cupholder count is strong, with two in the front and four in the back, and connectivity runs to two USB ports, an auxiliary-in socket, dual SD card readers, and two 12V outlets. There’s also a wireless charge bay for Qi-enabled devices if you opt for the ‘Technik package’ (more on that later).
Sensor control means the boot unlocks and opens automatically (if the smart key is detected) with a kicking motion under the rear bumper. Load space with rear seats upright is 465 litres VDA (10L more than the outgoing model), and the rear seat backs split-fold 40/20/40 to enhance flexibility and open up extra space for longer or bulkier loads.
There are four cargo tie down points and a luggage net supplied, plus a first-aid kit in a netted cubby on the passenger side, and another netted storage space (taking advantage of the space behind the rear wheel tub) on the driver’s side. The spare is a space saver.
Price and features
In a classic less-is-more (money) scenario, the $189,529 BMW M4 CS cops a decent serving of standard features, but misses out on some of the luxury trimmings included on the next-rung-down M4 Competition ($156,710).
Standard inclusions run to adaptive LED headlights (including 'BMW Selective Beam' anti-dazzle tech), adaptive M suspension, combination 'Merino' leather/Alcantara seat trim, Alcantara-wrapped 'M' sports steering wheel (with blue/red stitching), a configurable head-up display, a 'BMW Individual' Anthracite roofliner, 'Comfort Access' (keyless entry and start), plus the 'iDrive6' multimedia system (managed via controller, touch or voice) running through an 8.8-inch, high-definition screen.
There are also big 10-spoke forged alloy rims, front-seat heating, sat nav, automatic headlights, rain-sensing wipers, front and rear park distance control, 'Surround View' parking assist, and the 'BMW ConnectedDrive' suite ('BMW Connected+' smartphone app, real-time traffic info, concierge services, and more).
That's a heavyweight equipment list for a car that's all about lightness. Inside, besides the basic door and centre console arrangement, the other significant concessions to kilo stripping are a 'specially adapted' 12-speaker version of Harman/Kardon's 'Surround Sound' audio system with DAB+ digital radio (16-speaker in the Competition), and a simplified, single-zone climate control set-up (dual-zone in the Competition).
Kind of like the CEO wearing a Swatch watch; they're wealthy and powerful, but 'all about performance', so they wear a functional, conspicuously un-flashy timepiece. They still live in a $10m penthouse apartment, though.
Cost of entry to the Audi RS 5 Coupe club is $156,600 (before on-road costs); exactly $900 less than the most recent price for the superseded car.
And what’s more, according to Audi, the vast majority of first-gen RS 5 Coupe buyers hit the options list hard, to the tune of around $24k-worth of extras on average (some people would buy another small car with that cash).
So, to surprise and delight prospective buyers of this new version, a whole lot of extra fruit has been piled onto the car’s standard equipment list… and yes, it’s loaded.
Headline inclusions are three-zone climate control air (with ventilated glove box), ‘Dynamic Ride Control’ (with adaptive damper control), LED headlights (including LED DRLs), the nappa leather trim (door and side panel trim inserts in Alcantara), plus a panoramic sunroof (electrically tilting and opening, with electric sun shade).
Then, the RS sport front seats are a story in themselves. Electric adjustment (with memory for the driver) is a given, but they’re also heated, feature pneumatic side bolster adjustment, electric lumbar support, a massage function, and manual extendable thigh support.
But wait, there’s (a lot) more. The base price also includes an extended upholstery package, with the lower part of the centre console, door armrests and door pull handles trimmed in ‘man-made leather’, adaptive cruise control with ‘Stop&Go’ (including traffic-jam assistant and distance indicator), keyless entry and start, heated, folding and auto dimming exterior mirrors (with memory), plus LED tail-lights with dynamic (scrolling) indicators.
There’s also privacy glass (dark tinted rear and rear side windows), a headlight washer system, an RS sport exhaust (with gloss black oval tailpipes), an anti-theft alarm (with interior monitoring, tow-away protection and tilt sensor), interior ambient lighting (with 30 selectable colours and five colour profiles), a frameless, auto-dimming interior mirror, plus door-sill trims with aluminium inlays and illuminated RS emblems.
Okay, deep breath. Also included are ‘Park assist’ (helps steer the vehicle into parallel or perpendicular spaces), 360-degree cameras (four wide-angle cameras covering the area immediately around the vehicle for easier manoeuvring), auto headlights, rain sensing wipers, the ‘Virtual Cockpit’ (digital configurable colour instrument cluster), stainless-steel-finished pedals, and a flat-bottom, multifunction RS sport leather steering wheel.
And now we get to the multimedia, including ‘Audi connect’ (Wi-Fi hotspot and Google services), Apple CarPlay and Android Auto support, and a Bang & Olufsen ‘3D Sound System’, with no less than 19 speakers, and 755 watts delivered via a 16-channel amplifier.
It also features DAB+ digital radio, ‘MMI navigation plus’, including an 8.3-inch high-res colour display, 10 GB flash memory, and integrated voice control.
That’s a motherload of stuff, and doesn’t even consider the laundry list of standard active and passive safety tech covered in the safety section below.
If all that isn’t enough, there are a series of individual options on offer, like a carbon-fibre roof ($4900), ceramic brakes ($11,900), and milled-finish 20-inch alloys ($1600). Or feature bundles, including the ‘Technik package’ (colour head-up display, ‘Matrix LED’ headlights, and more), and ‘RS Design package’ (‘Audi phone box light’ wireless charging for Qi devices, an Alcantara-trimmed steering wheel, extra leather, lots of red stitching, and multiple RS logos).
Engine & trans
Like its E9 coupe forbear, the M4 CS is powered by an in-line six-cylinder engine, but things have moved on over the last 50 years, and the current (S55) engine offers a mechanical case study in the marriage of high-performance and efficiency.
The all-alloy unit features direct injection and twin turbos, the key drivers behind a stonking 600Nm of maximum torque (50kW up on the M4 Competition), available from 4000-5380rpm, and peak power of 338kW (+7kW), arriving at 6250 rpm.
It also features a 'charge air' (air-to-air) intercooler, 'Double Vanos' variable cam timing, and 'Valvetronic' variable valve lift (inlet and exhaust side).
The sleeveless cylinders use 'Electric Arc Wire Spray' technology to form a thin coating of iron on the cylinder walls, to save weight (no cast-iron liners) and reduce manufacturing complexity. And the engine's closed-deck design increases the block's torsional rigidity, enabling a substantial 10.2:1 compression ratio and use of a lightweight, forged crankshaft.
Transmission is a seven-speed 'M Double-Clutch' (M DCT) dual-clutch auto, complete with dedicated oil cooler, and drive is distributed across the rear axle via an electronically controlled, multi-plate 'Active M Differential'.
The RS 5 Coupe’s 2.9-litre V6 is based on the S4’s 3.0-litre unit, featuring a shorter stroke, and two turbos rather than a single, twin-scroll unit.
It’s an all-alloy design, featuring direct injection, variable inlet valve adjustment, continuous camshaft adjustment, and drive-by-wire throttle control.
With the turbos sitting inside the engine’s 90-degree V, the distances from the exhaust side to the turbos and then from the turbos to the inlet side are short, so they spool up quickly and boost power rapidly.
Maximum torque of 600Nm (+170Nm) is available from just 1900rpm all the way to 5000rpm, with maximum power of 331kW taking over from 5700 to 6700rpm (the latter number being the rev ceiling).
The transmission is an eight-speed auto, taking over from the first-gen RS 5’s seven-speed dual-clutch because of the new car’s additional torque.
It feeds power to all four wheels via the latest iteration of Audi’s quattro all-wheel drive system, with drive normally distributed 40/60 front to rear, but able to go as much as 85 per cent rear and 70 per cent front, with torque vectoring via the ESC system, and drive managed by a self-locking centre diff, and an electro-mechanical sport diff at the rear.
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 8.3L/100km, the twin-turbo six emitting 194g/km of CO2 in the process.
Over roughly 350km of city, suburban and freeway driving (much of it 'enthusiastic') we recorded 10.9L/100km (at the bowser) An impressive number for such a strongly performance-focused machine.
Minimum fuel requirement is 98 RON premium unleaded, and you'll need 60 litres of it to fill the tank.
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 8.8L/100km, the RS 5 emitting 199g/km of CO2 in the process.
Over 500km of twisting, central Tasmanian roads on the launch drive program, we averaged a dash-indicated 12.4L/100km, which represents some intense periods of ‘spirited’ driving, with a best of 11.9L/100km recorded on one slightly more sedate 120km city and outer-urban section.
You’ll need 58 litres of 98RON premium unleaded to fill the tank.
Let's get it out of the way. The M4 CS is fast. Anything running 0-100km/h in less than four seconds gains admission to a seriously rapid club, and BMW claims 3.9sec for this car (an exact match for the soon-to-arrive Merc-AMG C63 S Coupe).
We might have given the standard launch-control system a go, and may be able to confirm straight-line acceleration from step-off will compress your chest like an over-zealous lifesaver at CPR practice.
But just as impressive is the in-gear thrust, with 80km/h to licence loss (120km/h) covered in only 3.4sec. Which plays to the twin-turbo six's strength, with maximum torque arriving at a relatively high 4000rpm, and remaining on tap until 5380rpm.
Power doesn't reach its peak until 6250rpm, with the rev ceiling sitting at 7600rpm; impressively high for a twin-turbo engine.
Everything from the DSC, ABS, and active suspension to the active diff, electrically assisted steering and seven-speed, dual-clutch transmission has been tuned specifically for the M4 CS.
The 'M DCT' auto is agreeably civilised at parking speeds, yet shifts positively and rapidly, especially in manual mode, under pressure at higher pace.
An M Sport exhaust system features electronically controlled flaps sitting directly in front of the rear mufflers, and varies the intensity of the accompanying soundtrack according to drive mode and level of aggression. It sounds suitably angry, but those hoping for the soaring purity of say the (S54) naturally aspirated in-line six found under the bonnet of the E46 M3 will be left hankering for the good old days.
Front suspension is a modified MacPherson strut design, with a five-link set-up at the rear, and data from wheel-acceleration sensors on each corner is used to recalibrate each damper's setting every 2.5 milliseconds.
The drivetrain, suspension and steering can each be dialled into 'Comfort', 'Sport' or 'Sport+' modes, and the CS's ride changes markedly in the switch from Comfort to Sport; the former proving compliant and smooth rolling over rough city surfaces, and the latter keeping things reassuringly buttoned down on a B-road blast.
Although BMW says that, unlike the M4 GTS, it has deliberately steered the M4 CS away from a focus on the circuit (no roll cage, no adjustable splitters or spoilers) we'd suggest it's best to keep the Sport+ suspension setting for track days unless you're already planning on replacing some of your older fillings.
Speaking of track days, BMW says the M4 CS's dynamics were “honed on the Nurburgring Nordschleife” where it's recorded a best lap time of 7:38, which is as fast as a Ferrari 458 Italia and Lexus LFA. That's very, very impressive.
At 1580kg the M4 CS is 35kg lighter than the M4 Competition (1615kg), and just five kegs under the Pure (1585kg), so despite all the light-weighting hype it's worth remembering we're still looking at a car tipping the scales at just under 1.6 tonnes.
The electromechanical steering can also be tuned through the three performance modes, and Sport delivers the best combination of quick turn-in, agreeably linear assistance and decent road feel.
But putting the CS's power down out of even moderately quick, tight corners is less convincing. The big forged-alloy rims (19-inch front, 20-inch rear) are shod with ultra-high-performance Michelin Pilot Sport Cup 2 rubber (265/35 front – 285/30 rear).
Squeezing the power in smoothly but quickly, the semi-slick tyres feel like they need more heat in them. Without going anywhere near the DSC's more taily 'M Dynamic' modes, and despite the active diff, the rear of the car will squirm when fed full throttle acceleration on corner exit, unsettling overall balance. Less edgy Michelin Pilot Super Sport tyres are a no-cost option.
The standard M sport front seats look the part (the M4 logos in the backrest illuminate!) and grip firmly without any discomfort for this 183cm tester.
And when it comes to slowing everything down, the standard brakes run to big ventilated discs front and rear, clamped by four-piston calipers at the front, and two-piston at the rear.
Our test example was optioned with the $15,000 'M carbon ceramic' package featuring humungous carbon rotors, thumping six-piston calipers up front, and four-piston rear. For that money you'd expect Le Mans-style braking performance, and while we didn't exactly put them to a 24-hour high-speed test, firm application of the left-hand pedal will consistently stand the car on its nose.
First impressions are dominated by the V6 twin-turbo engine’s mountainous torque. In fact, it’s less a peak and more of an imposing plateau, with 600Nm available across a broad spread from 1900rpm to 5000rpm.
Maximum power takes over from 5700 to 6700rpm, so from go to whoa there’s monumental thrust lurking under your right foot. Audi claims 0-100km/h in 3.9sec, which is six tenths faster than the previous V8, with the RS 5 able to surge on to an electronically controlled top speed of 250km/h (280km/h with the limiter optionally removed). This car is a rocket.
The eight-speed auto is smooth yet quick and positive. And in terms of the speed and definition of shifts, you’re not really losing anything relative to the seven-speed dual-clutch in the old RS 5.
Suspension is a five-link design front and rear, the first-gen RS 5 using a trapezoidal link set-up at the back. This car’s lighter engine (a hefty 31kg down) improves balance with less weight on the front axle improving steering response and agility. Even at 1.7 tonnes, the car feels agile, planted, and puts its power down with reassuring authority. Damping is outstanding.
Rubber is high-end Hankook Ventus S1 evo2s, and despite their 20-inch size, they are surprisingly compliant and quiet. And speaking of noise, the previous car’s atmo V8 was raucous music to any performance enthusiast’s ears, and somehow Audi’s managed to tune in its characteristic, guttural growl for this V6, mainly using flaps in the exhaust. Not quite as free and angry as the V8 it replaces, but satisfyingly gruff all the same.
The engine and exhaust noise won’t be an issue if you’ve never heard the old one. This car sounds great, and the mid-range is so beautifully meaty, that on a twisting B-road a smile naturally appears on your face.
‘Drive Select’ allows tuning of the engine and gearbox, suspension, sport diff and exhaust. But beware the ‘Dynamic’ suspension mode, if you have fillings they’re likely to rattle free. Best left for track days.
The (electro-mechanical) steering feels great, with linear response, and road feel is also good. Overall, the RS5 Coupe delivers a truly involving drive experience.
The brakes are pretty much professional grade, with big six-piston calipers up front and two-piston floating calipers at the rear. Rotors are ventilated and perforated all around (375mm front / 330mm rear).
If you’ve got a lazy 12 grand burning a hole in your pocket you can add the carbon-ceramic package, but the standard brakes are fantastic, and you’d have to be a dedicated track-day fanger to need them.
The BMW 4 Series (and by extension the M4 CS) hasn't been assessed for crash safety by ANCAP or EuroNCAP, but boasts a solid array of active and passive safety tech, with several notable omissions.
To help you avoid a crash the M4 CS features ABS, brake assist, EBA, EBD, 'Cornering Brake Control' (CBC), Dynamic Stability Control (DSC), Dynamic Traction Control (DTC) and dry braking, 'Emergency stop signal', lane-departure warning and a tyre-pressure-monitoring system.
M4 owners also receive a complimentary BMW Intensive Driving Experience course (one person per vehicle purchase), which is arguably the best crash prevention measure of all.
But significantly, there's no AEB (Auto Emergency Braking) or other, more recent safety bits and pieces (found on other current BMW models) like blind-spot monitoring, forward-collision warning, fatigue detection, reverse collision avoidance, or speed-sign recognition and warning.
If all else fails and a collision is unavoidable passive safety tech runs to head and side airbags for the driver and front passenger, as well as curtain airbags covering front and rear. But again, things like an active bonnet and active front head restraints, fitted elsewhere in the BMW world, are MIA.
There are ISOFIX child-restraint anchors with top tether points in each of the rear seat positions.
The RS 5 Coupe doesn’t leave much on the table when it comes to active and passive safety.
Attention assist, ‘Audi pre-sense city’ (with AEB and pedestrian detection), ESC (with electronic wheel-selective torque control), ABS, ASR, EDL and Brake Assist are all standard.
There’s also a tyre-pressure-monitoring system, adaptive cruise control (including a distance indicator and speed limiter), active lane assist, ‘Audi parking system plus’ (front and rear with visual display), ‘Audi pre-sense front’ (provides collision mitigation up to 250km/h), blind-spot warning, collision-avoidance assist, rear cross traffic assist, turn assist (monitors oncoming traffic when turning right at low speeds), an exit warning system (detects cars and cyclists when opening doors), and auto high beam.
And if all that’s not enough to help you avoid a crash, there are six airbags on board (front airbags for driver and passenger, side airbags for front passengers, and head-level curtain airbags for front and rear).
Warranty cover is three years/unlimited km, with 24/7 roadside assistance included for three years, and additional support from BMW 'Servicemobiles' (07:00 – 23:00 every day) staffed by trained techs and stocked with key service parts.
Maintenance on all BMW 4 Series models is controlled by a 'Condition Based Servicing' system which piles real-time data (mileage, time since last service, fuel consumption, and how the car has been driven) into a specific algorithm to determine whether an annual vehicle inspection or (oil) service is due.
Audi provides a three year/unlimited warranty, with three years paint cover, and a 12-year rust perforation guarantee. ‘AudiCare’ 24-hour roadside assistance is complimentary for three years.
The recommended service interval is 15,000km/12 months, and the ‘Audi Genuine Care Service Plan’ is available to cover scheduled servicing for three years/45,000km (whichever comes first).
