McLaren 540C vs Cadillac Lyriq

What's the difference?

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.

It's got a couple of quirks, but the Cadillac Lyriq is a pretty convincing, and definitely American, take on a premium electric vehicle in Australia. The only issue, I think, is that, while the brand is obviously iconic in the USA, it's not that well known in Australia, and we are a market now awash with pretty good, and often much cheaper, EVs from China. It's a hyper-competitive market. Only time will tell if Cadillac can convince Australians that its badge belongs among the European premium marques.

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 Cadillac looks… well, it looks American, right? A kind of difficult-to-describe Americanness that’s somewhere between an SUV and state car.

That’s not an insult, by the way. I personally think the Lyriq looks kind of pretty, with its bold elements countered by the surprisingly gentle touch applied in places, like its razor-thin daytime running lights (DRLs).

I’ve got to say, it doesn’t look much like any of the other new SUVs arriving, or a knock-off German brand. It’s got its own persona.

The cabin of the Lyriq is predictably plush, with comfy massaging seats, soft-touch materials and plenty of tech, but it is a little shiny and busy in places for my tastes. Minimalist this is not.

But I do like the fact that – when I’ve got Apple CarPlay hooked up – I can just leave the screen be. My driving stuff is accessed by the wheel, and everything else I want is accessible through physical buttons.

There are some strange elements, though. The grab handle on the driver’s side, which isn’t replicated on the passenger side, is odd, and likely a byproduct of the factory moving the steering wheel. Some of the central storage bins are too small to be really useful, and I hate gloveboxes that can only be opened through the screen.

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.

It’s a big boat, the Lyriq, stretching more than five metres long and almost two metres wide. That’s not much shorter than, and in fact slightly wider than, something like a Nissan Patrol, just to put it into perspective. Though of course it’s nowhere near as high as a proper 4WD.

Predictably, though, its dimensions mean plenty of room in the boot, which opens to reveal a very useable 793 litres of luggage space. Drop the seats, and that number grows to a massive 1722 litres. 

But the Lyriq does without any spare wheel of any kind. A tyre repair kit is your only option.

Now, the backseat. And I know this is likely only of interest to parents of newborn babies, but that’s me, so I noticed. These are some of the best ISOFIX attachment points I ever used. Usually you’re fumbling around between the seat cushions trying to line up the latch points, but the Lyriq's solution — while perhaps not the most visually alluring – puts the brackets beneath plastic lift-up flaps, and they're so damn easy to use. 

But there are some quirks in the backseat, too. Those same ISOFIX attachment points, which are so great for baby seats, are less great for the adults actually sitting in the back. You can feel the hard plastic covers, and what feels like the bracing bar running across the backseat, beneath the cushions. It's not diabolical, and if you shift your rear-end forward slightly you can't feel it at all, but it's a strange quirk all the same.

Elsewhere in the backseat, there is plenty of room for backseat riders, and you can control your own temps, too.

You can have your Cadillac Lyriq in two flavours — the Luxury, yours for $122,000 plus on-road costs. Or the Sport, which is two grand more, listing at $124,000.

Perspective time. The new Polestar 3 starts at around $118k, but climbs to more than $130k for the dual-motor options. The similarly sized BMW iX starts at more than $140k, and the Mercedes-Benz EQE is north of $135k. So if you consider the Cadillac a ready-made premium brand, then its looking like a relatively sharpish one. 

Cadillac says the changes between the trims largely focus on the “aesthetic signature” rather than any major equipment differences. The Luxury gets chrome highlights, for example, while the Sport gets a darkened design theme, including the wheels, body highlights and windows.

Both trims are otherwise identically equipped, which means 21-inch alloy wheels, full LED lighting, an electric sunroof, an auto-opening boot and a touch-to-open charging port.

Inside, there’s a 33-inch digital dash, with Apple CarPlay and Android Auto, wireless device charging, a thumping 19-speaker AKG stereo and USB connection points galore.

The leather-wrapped front seats have heating, ventilation and a massage function, there’s heating and cooling for the window seats in the back, tri-zone climate control and there’s 126-colour ambient interior lighting.

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.

All Aussie Lyriqs are dual-motor affairs, with an electric motor at each axle producing a total 388kW and 610Nm, which in a car this big, which weighs just under 2.7 tonnes, is more than enough to get the Caddy up and moving, but not enough to make it feel like a supercar. The two motors mean AWD, of course.

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.

The Lyriq is equipped with a 102kWh lithium-ion NCMA battery, which delivers an ok 530km on the combined cycle. I say 'ok', because the BMW iX offers 600km-plus, while the dual-motor Polestar 3 is more like 630km claimed. Energy consumption is a claimed 22.5kWh per 100km on the combined cycle. 

When it comes to plugging in, the Lyriq is set up for 190kW DC fast charging, with the brand promising 128km of range in 10 minutes, or 10 to 80 per cent in just under 30 minutes. At home, a 7kW wall ox will deliver more like 43km an hour.

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 first thing you notice behind the wheel of the the Lyriq is just how whisper-quiet it is on the road. Cadillac makes a big deal about its 'Active Noise Cancellation' tech that's deployed here – it uses sensors to monitor road vibrations and the like, and then uses the car's stereo to create what it calls an 'anti-noise' signal.

It all sounds pretty high-tech and complicated, but it also works, with the Lyriq a seriously quiet and composed way to get around, with only the artificial EV noise really noticeable in the cabin.

Even travelling past freeway speeds, the Lyriq remains quiet, which does lend the whole experience a sort of premium vibe.

The Cadillac is also one of those cars that thinks solidity means premium, from the solid 'thunk' of the doors shutting to a general heft and weight to the steering, there's nothing feather-light or agile about the Lyriq experience, but it does all feel a little artificial, and like it's trying to be heavy on purpose.

The Lyriq, then, is no out-and-out performance car – it's 2.5-tonne-plus kerb weight and Olympic swimming pool dimensions largely put an end that – but it's more than brisk enough to get up and moving, with its twin-motor powertrain finding grip even in slippery conditions. It's brisk, but not brutal.

The Lyriq hasn't been tested or tuned in Australia, but happily it doesn't have that floaty, wafty suspension style so popular in the USA. This one feels to have at least had an international tune, which removes some of that marshmallow softness and makes you feel connected to the road.

The steering, too, feels direct enough and easy to predict, and the overall impression is one of quiet, calm motoring, which is probably what it says on the tin of any premium vehicle.

The Lyriq hasn’t been crash-tested in Australia, but it did get a five-star equivalent in American testing. There’s autonomous emergency braking (AEB) with pedestrian protection and junction assist, as well as active blind spot monitoring and assist. There’s also a side bicycle alert to stop you opening your door into someone, rear pedestrian alert, adaptive cruise and a total eight airbags, including knee bags for the driver and front passenger.

Interestingly, the Lyriq ditches those annoying safety bings and bongs for a novel, and far less intrusive approach which involves sending gentle vibrations through, well, your backside if the vehicle senses incoming danger.

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.

Cadillac has built a pretty convincing ownership package around the Lyriq, which begins with a five-year, unlimited-kilometre warranty, and an eight-year, 160,000km battery warranty. Beyond that, you also get five years of servicing, and five years of roadside assistance, free. 

Then you get a year’s free public charging through the Chargefox network and a free home wall box charger. If you have a wall box, or don’t want one, you can trade the home charging for an extra two years of free public charging.
