McLaren 540C vs Lexus LC

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.

Stunning to behold, and even more so to listen to, the LC 500 Convertible with no doubt turn as many heads as its owners surely want it to. It's not the final word in performance, but it's a lavishly equipped transporter none the less.

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.

It’s eye-catching, the LC 500, if big, bolshy convertibles are your thing, and especially viewed front-on, where the aggressive nose design ends in a sharp crease in the mesh grille. I love the headlight design, too, which bleeds back into the body work, but also merges with the vertical light cluster that bookends the grille. 

The side view is all shining alloys and sharp body creases, too, leading to an oversized boot that stores the fabric, aluminium and magnesium roof structure, which drops or raises in 15 seconds at speeds of up to 50km/h. The design fits into what Lexus calls an “impossibly small space behind the seats”.

Inside, it’s a snug but luxurious space, wrapped largely in leather and equipped with a wealth of technology. It’s a point we’ve made before, but why Lexus perseveres with its trackpad infotainment control technology is beyond us, but there’s no denying the cabin of the LC 500 is a wondrous place to spend time. 

We particularly like the integration of the centre screen, which is recessed beneath the leather-wrapped edge of the dash. While some look like an afterthought, this appears to have been included in the broader design philosophy.

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 not, really. But then, what were you expecting?

As mentioned above, the interior feels snug for upfront riders, but not in a bad way. More that elements of the interior feel like they’re reaching out to greet you, leaving you with the impression of being tucked into the cabin.

Backseat riders are out of luck, though, with the seats really only reserved for emergencies. Legroom is tight, and while Lexus promises the roofline is about on-par with the Coupe, it’s not going to be a comfortable journey.

The LC 500 Convertible stretches 4770mm in length, 1920mm in width and 1350mm in height, and it rides on a 2870mm wheelbase. It will sit four at a pinch, and provide 149 litres of luggage space.

There are two ISOFIX attachment points in each of the rear seats, as well as top-tether points.

It costs $214,000 - and that’s rather a lot of money - but unlike some premium and luxury cars, with Lexus, once you’ve handed over the cash, that’s it. There’s no tempting option list to lure you into parting with even more of your hard earned. 

And I mean that literally - Lexus proudly proclaims that “there is no option list” for the LC 500 Convertible, so suffice it to say it arrives with plenty of gear. 

Take a deep breath…

You get 21-inch two tone alloys, triple-stack LED headlights, keyless entry, retractable door handles and rain-sensing wipers outside, while inside, you’ll find dual-zone climate, leather-accented seats which are heated and ventilated, neck-level heating for when the roof is down, a heated steering wheel and sports pedals. 

The tech stuff is handled by a 10.3-inch centre screen with Apple CarPlay, Android Auto and on-board navigation, both of which are controlled via Lexus’ impossible-to-kill touchpad. There’s a second, 8.0-inch screen for the driver, and the lot pairs with an impressive 13-speaker Mark Levinson stereo.

There’s also a heap of safety stuff, but we’ll come back to that in a moment.

If that’s not enough for you, you can spring for the Limited Edition, which is $234,000 for each of its 10 available examples. It arrives in a unique Structural Blue hue, with a white leather interior with blue highlights. It is designed to be the most blue of blues, too, with Lexus saying the paint colour was the result of a 15-year research project. Which sounds like a thrilling way to spend a decade and a half.

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.

It’s a lusty power plant, this one, and not something you immediately expect to find in a luxurious Lexus convertible.

The 5.0-litre V8 produces 351kW and 540Nm - 260kW of which arrives from 2000rpm - and it sounds like a God of Thunder as it’s doing it. 

It pairs with a 10-speed automatic and sends all that grunt to the rear tyres, with Lexus’ Active Cornering Assist and a mechanical limited-slip differential helping you to not make a mess of things when tackling corners. 

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.

Remember when I said it was lusty V8? When has that ever been good news for fuel use?

Lexus reckons you’ll get 12.7L/100km on the combined cycle, but the temptation of all that grunt will pretty much ensure that never happens. Emissions are pegged at 290g/km of C02.

The LC 500 Convertible’s 82-litre fuel tank only accepts 98RON fuel.

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.

It’s a tough nut to immediately crack, the LC 500 Convertible.

It feels like it really wants to be a super-accomplished performance car, and on longer, more sweeping bends it is, with that thick flow of power ensuring you simply surf through corners before rocketing out the other side, the air filled with that growling exhaust note as your right foot finds its way to the carpet.

But on the tighter stuff, there are some factors that play against it. The suspension feels sorted and that engine is always willing to deliver, but for mine, the steering and brakes felt a little disconnected from the experience, not inspiring much in the way of late-braking confidence. And then there’s the sheer two-tonne-plus weight of the thing, which can’t be totally hidden, even by Lexus’ best wizardry.

Don’t get me wrong, it’s very capable, even on surprisingly tight stuff. It’s just that there’s something of a disconnect between car and driver. 

That’s not a bad thing, really. Are you really buying a premium convertible to attack a mountain pass? Probably not. And keep it flowing through corners and the LC 500 Convertible will keep a smile painted on your face, owing mostly to wave of torque you can ride to your destination. 

Hovering your foot over the accelerator must surely be what the President feels like whenever he stands near the nuclear football, with that big V8 always ready to turn on the fireworks. 

Away from the red mist, you’ll find the LC 500 Convertible positively flows from destination to destination, the 10-speed gearbox - which can feel flustered at pace - seamlessly flicking through its options, and the ride in its most comfortable settings disposing of most road imperfections before they enter the cabin. 

The cabin is also very cleverly insulated, not just when the four-part roof is up, but also when it’s down, with the climate and ambience of the interior largely unaffected by what’s going on in the outside world.

The Lexus LC 500 Convertible arrives with six airbags, a reversing camera with guide lines, parking sensors, and the usual suite of traction and braking aids, but there’s much more to the safety story, too. 

The more high-tech stuff includes parking sensors, pre-collision assist with AEB, lane keep assist, blind-spot monitoring, rear cross-traffic alert and active cruise, as well as bespoke convertible safety gear, like active roll bars that deploy when the car is in danger of rolling over, protecting the occupants beneath that soft roof.

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.

Lexus vehicles are covered by a four-year, 100,000 kilometre warranty, and the LC 500 Convertible requires servicing every 15,000kms. 

Lexus's Encore ownership program includes pick-up and drop-off servicing, but the new Encore Platinum level for owners of its more exclusive models unlocks even more stuff.

One is a new On Demand service, which allows owners to book a different style of car when heading off on a holiday or business trip. The loans are available in your state or somewhere else in Australia if you're travelling, with your car waiting for you at Qantas Valet for you when you arrive.

The On Demand service is available on four occasions over your first three years of ownership (which is also the length of the Encore Platinum membership).
