Audi Sq6 E-Tron vs McLaren 540C

What's the difference?

When it comes to a performance electric SUV, the Audi SQ6 e-tron is a fine example and showcases a masterclass in design. It drives and handles beautifully, even if it’s not as fun as I expected.

The technology looks amazing and I'm sure the little bumps we experienced will be ironed out with a software update.

The SQ6 will suit a smaller family best but the decent driving range and fast charging capabilities means regional families might like it too.

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 SQ6 has a distinct look compared to the other mid-size SUVs in Audi’s stable with panelling that lacks some of the severe pleating of its cousins, instead incorporating swoopy lines and a more pronounced moulding around the base of the car.

The sporty S styling is seen in the large 21-inch alloy wheels and red calipers but the customisable light designs inside and out really make this stand out.

The interior is sumptuously styled with Nappa leather and suede upholstery and trims, and sports front seats, while the use of displays in the dashboard makes the SQ6 feel like a spaceship.

However, the main panel curves towards the driver and it still feels accessible and intimate for a cockpit. The cabin looks as expensive as what you’d want it to look like at this price point.

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 cabin's primary objective seems to be one of passenger comfort. Everything you touch feels soft under hand and while seat padding is on the firmer side, all but the rear middle seat is comfy on a longer journey because of their extra functions.

The rear-row back rest has two recline positions and the seat beds offer long under-thigh support. The middle seat bulges up, and coupled with the compromised legroom, it won't be a nice seat for an adult.

The front row offers the best legroom and there is enough space in the rear for my six foot three brother to squeeze into (somehow) but I wouldn't want to be in the rear for a longer journey if you're super tall.

Access is good for each row with wide door apertures and seats that aren't positioned too high. There will be no groans getting in and out of the SQ6.

Up front the glovebox and middle console shoulder most of the storage burden but there is a handy flip-down drawer at the driver's knee for a wallet and a centre console with the charging stuff but it is an awkward space that could have been better utilised. Things tend to move around in there if not secured.

In the rear there are a couple of net map pockets, storage bins and a total of four drink holders but that's about it. The other amenities back there soften the lack of storage options as you get directional air vents, climate control, heated outboard seats and a couple of USB-C ports.

The technology on a whole looks amazing and the touchscreen multimedia display is responsive and logically laid out. You'll be able to figure it out quickly and I like that important functions, like climate control, and shortcuts are pinned to the screen as it makes it easier to access them when on the go. The Audi voice assistant can be activated by 'Hey Audi' if you don't want to fiddle with screens on the road.

The wireless Apple CarPlay was simple to set up but at the beginning of the week it did tend to get booted whenever the climate or massage functions were activated. This was annoying as you'd have to reselect CarPlay and jump back into whatever app you were in and when you're using the Map app, it feels disjointed. However, this sorted itself out by the end of my week.

On the whole, all the screens and their functions are user friendly but there were a couple of gremlins that needed a car restart to fix. Randomly, my volume became useless and the touchpad/buttons on the steering wheel stopped working.

I do like a normal button over touchpad controls as I find them more responsive but the touchpad controls on the driver's door were really easy to use and I like the family-friendly option of being able to individually apply the child-lock to the rear doors.

Rounding out the cabin is the large 526L boot which offers a level loading space and the ability to adjust the height via the adaptive S air-suspension from buttons in the rear.

The rear row has a 40/20/40 split, which opens up storage options again and there is a deep under-floor storage pocket that houses the tyre repair kit. A handsfree-powered tailgate comes standard, which I always appreciate and the massive frunk (64L) takes care of all of the cable storage.

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.

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.

The SQ6 is a fully electric all-wheel drive and has two motors, one located on each axle. Together they produce up to 380kW of power and 580Nm of torque, which means this can do a 0-100km/h sprint in just 4.3 seconds when the launch control is activated.

There are three regenerative braking levels and a one-pedal mode which can be selected by sliding the gear-selector into 'B' otherwise the other two modes can be selected via the paddles on the steering wheel. You'll get the best efficiency when B is selected but it does take a beat to get used to and if you time your stops right, it can function as a proper one-pedal action.

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.

The SQ6 has a lithium-ion battery with a large 100kW capacity and can accept up to 270kW on DC power, which is excellent. There are two Type 2 charging ports (on either side of the car) and one has a CCS enhancement which means you can charge this from 10 to 80 per cent capacity in as little as 21 minutes on a 270kW ultra-rapid DC charger.

It is more common to see a 50kW DC charger though and that charge time sits closer to an hour and 20 minutes.

On a home 7.4kW charger, you'll get the same percentage after 15 hours, perfect for an overnight recharge.

With a claimed WLTP driving range of up to 568km and energy consumption between 17.5 and 18.6kWh/100km, the daily commute and odd family road trip is more than covered with this model.

My average consumption popped out at 18.1kWh based on the trip computer and that’s a good result for how hard I’ve pushed it over country roads, in the city and on the highway. 

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.

Outside of the initial acceleration thrill, I have to say that the SQ6 sort of drives like a lot of the other Audi SUVs I’ve sampled. Which is fine because it’s dynamic and handles beautifully on the highway or city but it’s just not as fun as what I was hoping it would be. The power will satisfy everyone though. 

The different driving profiles and adaptive S air suspension really personalises the on-road experience when you want it and my favourite profile is Dynamic as the suspension and steering feels more performance focused, which I prefer. 

Ride comfort is up there with the best and you won’t really be bothered by the bumps in the road, even with the stiffer suspension, but road noise does creep in at higher speeds. 

The visibility all round is good despite thicker pillars but the rear visibility is narrow even before a car seat or passengers are back there. A digital rearview mirror would have been handy here. 

Just something interesting to note is that when you accelerate from a full stop, there can be a small lurch as if it’s rolled backwards or the brakes have held a tad too long. It’s so quick when it happens that it’s not annoying but it is noticeable in stop/start traffic.

The SQ6 is really simple to park and navigating small car parks feels like a dream. The dimensions are forgiving and the 360-degree camera system is top notch. 

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.

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.

The SQ6 is covered by Audi’s five-year/unlimited kilometre warranty and the battery is covered by an eight-year or up to 160,000km warranty, which are all standard terms for the class.

Audi also offers six years of complimentary roadside assistance and a servicing program for six years that costs $2080, which is competitive, and servicing intervals are at every two years or 30,000km. 

Audi includes the installation of a 7.4kW AC home charger, three charging cables and a one-year Chargefox public charging subscription with this model.

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.
