What's the difference?
Believe it or not, the McLaren 540C is an entry-level model. But you won't find anything remotely resembling rubber floor mats, steel wheels, or cloth seats here. This is a 'base' car like few others.
Revealed in 2015, it's actually the cornerstone of McLaren's three-tier supercar pyramid, being the most affordable member of the Sport Series, with the properly exotic Super Series (650S, 675LT and now 720S), and pretty much insane Ultimate Series (where the P1 hypercar briefly lived) rising above it.
So, how has this British upstart managed to build a world-beating supercar brand so quickly?
Only a few years ago, McLaren meant nothing to anyone outside the octane-infused world of motorsport. But in 2017, it's right up there with aspirational sports car big guns like Ferrari and Porsche, both of which have been producing road cars for close to 70 years.
So, how has this British upstart managed to build a world-beating supercar brand so quickly?
Everything you need to know to answer that question resides inside the stunning McLaren 540C.
Audi would probably prefer you not to realise this, but the five distinct versions of S4 and S5 on the market all pertain to a single performance and equipment formula spread across five different bodystyles.
Yes five, and this has been the case for more than a decade, with the S4 sedan and Avant wagon, A5 two-door Coupe, convertible Cabriolet and five door liftback Sportback all representing vastly different shapes for you to choose from, with the same underpinnings. This simply echoes the A4 and A5 ranges they’re based on of course, and BMW clearly thought it was a good idea too, given the 3 and 4 Series ranges were split into individual lines at the start of last generation.
Mercedes-Benz offers a similar array, minus the liftback, but is happy to wrap the whole lot under the C-Class label.
So, given that the A4 and A5 range scored a mid-life update a few months ago, it’s only logical that the changes flow on to the performance S4 and S5s, with the top-tier RS4 Avant following suit.
We’ve covered the latter in October, and now it’s the turn for the former, and CarsGuide was among the first to drive the updated S4 and S5 ranges at their Australian media launch last week.
The 540C is desirable on so many levels. Its dynamic ability, blistering performance, and stunning design make the cost of entry a value-for-money ticket. And the refreshing thing is, choosing a McLaren, with its focus on function and pure engineering, sidesteps the wankery that so often goes with ownership of an 'established' exotic brand. We absolutely love it.
The S4 and S5 range continues to represent a great formula for performance you can live with every day. They're arguably the sweetest balance Audi produces, actually. All come fantastically equipped, with cabins that feel truly special, and we’re lucky they can be had in a choice of five bodystyles.
In 2010 the recent rise (and rise) of McLaren Automotive really began, when its design director, the hugely respected Frank Stephenson, started to send things in a compelling direction.
He says McLarens are 'designed by air' and that intricately sculpted, wind-tunnel-driven approach to supercar beauty is clear in the 540C's shape.
It's aimed at so-called everyday supercars like the Audi R8, and Porsche 911 Turbo, yet it incorporates all the subtle aero tricks that define the brand's dynamic personality.
A serious front spoiler and a mix of large intakes low in the nose create a delicate balance between downforce and corridors for cooling air.
The dihedral design doors swinging up to their fully open position is a camera phone attracting, jaw dropping, traffic-stopper.
Broad strakes down the side, standing proud of the main bodywork, are reminiscent of a formula one car's turbulence reducing barge boards, and giant intake ducts channel air through to the radiators in the cleanest, most efficient way possible.
And the look is suitably spectacular. You could hang the dramatically carved doors in a contemporary art museum.
Barely noticeable flying buttresses extending from the rear of the main roofline make a big contribution to downforce, cooling and stability with a minimal drag penalty.
There's a delicate lip spoiler on the trailing edge of the main deck, and a giant multi-channel diffuser proves air flow under the car is just as carefully managed as that going over it.
But the 540C doesn't lack traditional supercar drama. The dihedral design doors swinging up to their fully open position is a camera phone attracting, jaw dropping, traffic-stopper.
The interior is simple, striking and single-mindedly driver-focused. The chunky wheel is completely unadorned, the digital instruments are crystal clear, and the seats are the perfect combination of support and comfort.
The vertical 7.0-inch 'IRIS' touchscreen is cool to the point of minimalism, managing everything from audio and nav, to media streaming and air-con, with low-key efficiency.
The S4 sedan and Avant have scored the bulk of design updates, with all new and recontoured side panels including the sedan’s C-pillar matching what was applied to the A4 earlier this year.
This is paired with new front and rear facias and lighting for a subtle but extensive rework of the fifth-generation S4’s conservative look.
The S5 Sportback, Coupe and Cabriolet get S5-specific new lighting and facias, but no sheetmetal changes. As before, the Coupe and Cabriolet ride on a 60mm shorter wheelbase than the Sportback, sedan and Avant.
The S5s also get Matrix LED headlights as standard which do a neat animated sequence when you unlock the car.
Other visual hallmarks include new S4-specific 19-inch wheels, with S5 stepping up to its own unique 20-inch wheel. The six-piston front brake calipers are appropriately painted red, and there’s S-specific adaptive dampers under there too. All variants aside from the Cabriolet get a lip spoiler on the rear.
On the inside, there’s a new centre console and bigger 10.1-inch multimedia screen, while the Audi Virtual Cockpit driver instrument display now offers a hockey stick-style rev counter in additional to traditional dial layouts.
There are some cursory concessions to practicality… like a glovebox, a single cupholder under the dash at the leading edge of the centre console, a small bin between the seats, housing multiple USB outlets, and other storage options here and there.
The latter includes a shelf at the top of the bulkhead behind the seats, marked with a specific label saying (words to the effect of) 'don't put stuff here', but that's more about objects flying forward in a high-G deceleration, which in this car is more likely to be the result of hitting the brakes, rather than a crash.
But the 'big' surprise is the 144-litre boot in the nose, complete with light and 12 volt power outlet. It easily swallowed the CarsGuide medium sized, 68-litre hard shell suitcase.
In terms of getting in and out, make sure you've done you warm-ups because frankly it's an athletic challenge to maintain composure and get the job done either way. Despite best efforts, I hit my head a couple of times, and aside from the pain it's worth pointing out that being a follicularly-challenged person I'm forced to display abrasions in full public view.
The biggest practicality change among the five S4 and S5 variants is their upgrade to the latest version of Audi’s MMI multimedia system, which steps up to a 10.1-inch touchscreen and drops the scroll wheel from the centre console.
It also boasts ten times the computing power of the version it replaces and uses this and an on-board sim card to access Google Earth maps for navigation and Audi Connect Plus that offers driver information such as fuel prices and parking information as well as point of interest search and weather information, plus the ability to make emergency calls and seek roadside assistance.
There’s also a wireless phone charger, but using Apple CarPlay will still require a cord as per Android Auto.
I only drove the S4 Avant and S5 Sportback at their media launch, which are clearly the most practical of the five, but from our experience with the previous versions, each looks after its occupants well in terms of space and storage. Back seat accommodation is clearly not a priority in the Coupe and Cabriolet, but there’s three other variants if that’s what you’re looking for.
The Cabriolet can open its automatic folding soft top within 15 seconds, at speeds of up to 50 km/h.
At $331,500, we reckon the McLaren 540C is a supercar bargain. For just on $140k less than a Ferrari 488 GTB it delivers equivalent visual drama, and isn't far behind on speed and dynamic ability.
Standard kit runs to climate control air con, an alarm system, cruise control, remote central locking, LED headlights, tail-lights and DRLs, keyless entry and drive, a limited-slip differential, leather steering wheel, power folding mirrors, four-speaker audio, and a multi-function trip computer.
'Our' car featured close to $30,000 worth of options; headline items being the 'Elite - McLaren Orange' paint finish ($3620), a 'Sport Exhaust' system ($8500), and the 'Security Pack' ($10,520) which includes front and rear parking sensors, a reversing camera, alarm upgrade and a vehicle lifter that raises the front of the car an extra 40mm at the push of a column stalk. Very handy.
And the signature orange shade follows through with orange brake calipers peeking out through the standard 'Club Cast' alloy rims, and similarly coloured seatbelts inside.
As I mentioned above, the S4 and S5 line-up are in many ways the same, but also different, and these differences result in a price span of $20,500 between the S4 sedan and the S5 Cabriolet.
The former is now $400 cheaper with a list price of $99,500, with the also-$400 cheaper S4 Avant not far beyond at $102,000.
The S5 Sportback and Coupe are now $600 more expensive at an equal list price of $106,500, while the swish folding soft top of the S5 Cabriolet pushes it up to $120,000 (+$1060).
Equipment levels are consistent across all five variants aside from the S5s getting Matrix LED headlights as standard and one inch larger 20-inch wheels.
Key details include Nappa leather trim with front sport seats with seat heaters and massage function, a Bang & Olufsen sound system which spreads 755W across a total of 19 speakers, brushed aluminium inlays, head-up display, coloured ambient lighting, tinted windows and metallic paint.
Over the past 12 months, the S5 Sportback has proven to be the most popular of the five variants by far, accounting for 53 per cent of sales, with the S4 Avant next in line at 20 per cent, the S4 sedan making up 10 per cent, and the S5 Coupe and Cabriolet combining to make up the remaining 17 per cent.
Aside from you and a passenger, the most important thing sitting between the 540C's axles is the 3.8-litre (M838TE) twin-turbo V8.
Developed in collaboration with British high-tech engineering specialist, Ricardo, McLaren's used it in various states of tune across different models, including the P1, and even in this 'entry-level' spec it produces enough power to light up a small town.
In 540C trim, the all-alloy unit delivers 397kW (540 metric horsepower, hence the model designation) at 7500rpm, and 540Nm from 3500-6500rpm. It uses race-derived dry sump lubrication, and a compact flat plane crank design, favoured by Ferrari and others in high-performance engines.
While vibration damping can be an issue with this configuration, it allows a much higher rev ceiling relative to the more common cross plane arrangement, and this engine screams up to 8500rpm, a stratospheric number for a road-going turbo.
The seven-speed 'Seamless-Shift' dual-clutch transmission sends drive exclusively to the rear wheels and comes from Italian gearbox gurus Oerlikon Graziano. It's been progressively refined and upgraded since its first appearance in the MP4-12C in 2011.
Audi has taken an ‘if it ain’t broke’ approach with the mechanicals, with all S4 and S5 models unchanged with this update. So the centrepiece continues to be the single-turbocharged 3.0-litre V6 that produces 260kW and 500Nm, with the latter available from a broad 1370-4500rpm.
The rest of the drivetrain is also unchanged, with the venerable but excellent ZF eight-speed torque converter auto paired with the Quattro all-wheel drive system that can send up to 85 per cent of drive to the rear wheels.
McLaren claims 10.7L/100km for the combined (urban/extra urban) fuel economy cycle, emitting 249g/km of CO2 at the same time.
For the record, that's six per cent better than the Ferrari 488 GTB (11.4L/100km – 260g/km), and if you take it easy on a constant freeway cruise, you can lower it even further.
But most of the time, we, ahem, didn't do better than that, averaging 14.5L/100km via the trip computer in just over 300km of city, suburban and freeway running.
Official combined fuel figures range from 8.6L1/00km for the S4 sedan to 8.8L/100km for the Avant, Coupe and Sportback, while the heavier Cabriolet steps up to 9.1L/100km.
All are pretty good considering their performance potential and the size of these cars, plus the fact that they only require 95 RON Premium Unleaded fuel.
All have a 58-litre fuel tank, which should enable a range of at least 637km between fills based on the Cabriolet’s figure.
The best word to describe driving this McLaren is orchestration. The 540C's dynamic elements flow seamlessly together to transform its operator into a conductor guiding a well-honed mechanical orchestra through an energetic concerto.
And slipping (carefully) over the carpeted bulkhead into the driver's seat is like dropping into an ergonomic masterclass. It feels like you're putting the car on, rather than getting into it.
Like all other current McLarens, the 540C is constructed around a one-piece, carbon-fibre tub, which it calls MonoCell II. It's super stiff, and just as importantly, light.
McLaren quotes a dry weight (no fuel, lubricants, or coolant) for the 540C of 1311kg, with the kerb weight a stated 1525kg (including a 75kg passenger). Not featherweight, but with this kind of power sitting a few centimetres behind your head, it's not a lot.
The engine sounds brilliantly guttural, with lots of exhaust roar managing to find a way past the turbos.
A sophisticated launch control system means zero to licence loss is achieved in a flash (0-100km/h – 3.5sec), with jail time lurking if you ever decide to explore the 540C's 320km/h maximum velocity. And in case you're wondering, it'll blast from 0-200km/h, in just 10.5sec.
The engine sounds brilliantly guttural, with lots of exhaust roar managing to find a way past the turbos. Maximum torque is available across a flat plateau from 3500-6500rpm, and mid-range punch is strong. However, the 540C is anything but a one-trick pony, or is that 540 ponies?
The double wishbone suspension, complete with the adaptive 'Active Dynamics Control' system lets you channel all that forward thrust into huge cornering speed.
The switch from Normal, through Sport to Track progressively buttons everything down harder, and an ideal weight distribution (42f/58r) delivers fantastic agility.
Feel from the electro-hydraulic steering is amazing, the fat Pirelli P Zero rubber (225/35 x 19 front / 285/35 x 20 rear), developed specifically for this car, grips like a Mr T handshake, and the standard 'Brake Steer' torque vectoring system, which applies braking force to optimise drive and minimise understeer, is undetectable in the best possible way.
A console switchable 'Powertrain Control System' also offers three settings, and in the upper modes, shifts from the seven speed dual clutch 'box are eye-blink rapid.
The steering wheel paddles come in the form of a genuine rocker, so you're able to change up and down ratios on either side of the wheel, or one-handed.
You'll love catching a glimpse of the heat haze shimmering up off the engine in the rear-view mirror at the lights.
Hammer towards a quick corner and the reassuringly progressive steel rotor brakes bleed off speed with complete authority. Flick down a couple of gears, then turn in and the front end sweeps towards the apex without a hint of drama. Squeeze in the power and the fat rear rubber keeps the car planted, and perfectly neutral mid-corner. Then pin the throttle and the 540C rockets towards the next bend… which can't come quickly enough. Repeat, and enjoy.
But slotting everything into 'Normal' mode transforms this dramatic wedge into a compliant daily driver. Smooth throttle response, surprisingly good vision and excellent ride comfort make the McLaren a pleasure to steer around town.
You'll love catching a glimpse of the heat haze shimmering up off the engine in the rear-view mirror at the lights, and the (optional) nose-lift system makes traversing awkward driveways and speed bumps manageable.
The S4 and S5 range were already an excellent balance between everyday comfort and a genuine sporting edge, and nothing has changed with this update.
I spent time behind the wheel of the S4 Avant and S5 Sportback at their media launch, and both managed to deliver the proper Audi luxury experience over some pretty rough rural roads, while always feeling a bit more sporting than a regular A4 or A5. That’s with the Drive Select left in the default mode, but you can shift that sporting personality up a few notches (while scaling back the comfort), by selecting Dynamic mode.
My preferred means of adjusting their personality is by simply tugging the transmission selector back to activate S mode, which livens up the engine and transmission without stiffening up the suspension.
Across the five S4 and S5 bodystyles, there is some variance in performance potential, with the S4 sedan and S5 Coupe topping the performance chart with 0-100km/h boasts of 4.7s, with the S5 Sportback trailing them by 0.1s, the S4 Avant by a further 0.1s and the Cabriolet managing a still-fast 5.1s claim.
Another area I consider the S4 and S5s to get just right is their exhaust note. It is adaptive, but there’s nothing synthetic about it, and the generally muted and distinctly V6 burble is always there to remind you that you’re aboard a proper performance model, but not in such a way that it will annoy you, or your neighbours. Polite performance, if you will.
In terms of active safety, the car's dynamic ability is one giant safeguard against a collision, and that's backed up by tech features including ABS and brake assist (no AEB, though), as well as stability and traction controls.
But if a crunching-type incident is unavoidable, the carbon-composite chassis offers exceptional crash protection with dual front airbags in support (no side or curtain airbags).
Not a huge surprise that ANCAP (or Euro NCAP, for that matter) hasn't assessed this particular vehicle.
All S4 and S5 variants boast an impressive array of safety features, but there’s some interesting points when it comes to ANCAP ratings. Only four cylinder A4 models (therefore not S4) were given a maximum five star rating when tested according to less stringent 2015 standards, but all A5 variants (therefore S5) aside from the Cabriolet carry a five star rating based on the tests applied to the A4. So officially, the S4 is not rated, but the S5 Coupe and Sportback are, but based on the A4 rating that doesn’t apply to the S4. As with most convertibles, the Cabriolet is simply not rated.
The airbag count totals eight in the sedan, Avant and Sportback, with dual front airbags, plus side and curtain airbags covering front and rear.
The Coupe drops the rear side airbags, while the Cabriolet also drops curtain airbags, meaning there’s no airbags for rear seat occupants. The roof is made of folding fabric, there has to be some safety compromise.
Other safety features include front AEB that works up to 85km/h, adaptive cruise control with traffic jam assist, active lane guidance and collision avoidance assist that can automatically swerve, a 360 degree camera system, rear cross-traffic alerts, exit warning that can prevent you opening a door into an oncoming car or cyclist, and pre sense rear that can detect an impending collision from behind and prepare the seatbelts and windows for maximum protection.
McLaren offers a three year/unlimited km warranty on the 540C, and servicing is recommended every 15,000 km or two years, whichever comes first. No capped price servicing program is offered.
That's a lot of kays for a premium exotic like this, and some may not see 15,000km on the odometer… ever.
Audi continues to offer a three year, unlimited kilometre warranty, which is in line with BMW but lags behind the five years offered by Mercedes-Benz these days. This also contrasts with the five year norm among mainstream brands, which is punctuated by the seven year warranties of Kia and SsangYong.
Service intervals are a convenient 12 months/15,000km though, and the same five year ‘Audi Genuine Care Service Plan’ offers capped price servicing for the same $2950 total over five years applies to all S4 and S5 variants. This is only marginally more than the plans offered for regular petrol A4 and A5 variants, so you’re not being stung for the thoroughbred versions.
