Mercedes-Benz GT63 vs Rolls-Royce Spectre (bev)

What's the difference?

The Mercedes-AMG GT 63 S 4-Door Coupe fulfils the brief for an ultra-fast, ultra-luxurious, four-door weapon. The theatre that surrounds it will be enough for some, and those that want to a have a serious crack won’t be disappointed.

Personally, I was very much taken with the looks, and the feels, of the new Rolls-Royce Spectre, which delivers everything you’d expect from this brand, and seems to have lost nothing by switching to electric propulsion. The trick, it seems, in turning your brand into an EV one is to have made your cars silent in the first place.

But the real verdict comes from the people hurling their Spectre orders at the company, which has received so many of them it’s being forced to ramp up production. And 40 per cent of pre-orders are from new customers. Honestly, it’s as if they were all just waiting for an EV to drop a million on.

At a fraction over 5.0 metres long and just under 1.9 metres wide, the GT 4-Door Coupe is substantial, but an overall height under 1.5 metres sets up an aggressive stance that screams speed.

Fat guards are filled by dark 21-inch rims, and the low-set, bulging bonnet sits behind menacingly angular ‘Multi-beam’ LED headlights sitting either side of AMG’s now signature ‘Panamericana’ grille, looking ready to chew up and spit out lesser machines.

It has to be said that calling this car a four-door is a bit cheeky because technically it’s a hatch, and to my eyes at least the gentle rearward slope of the turret and large cargo door enhances the design’s understated power.

Inside is a sea of top-shelf nappa leather, with the twin-widescreen cockpit layout (two 12.3-inch hi-res displays) dominating the dash. Carbon-fibre is applied liberally (in the 63 S), and the grippy sports steering wheels and seats look and feel close to track grade.

Turbine-style air vents (four in the centre, and one at each edge) are now a Mercedes design signature (used in the back as well) and they combine with the brushed metal finishes around the broad centre console and on the pedals to deliver a sense of occasion and anticipation just sitting in the car. Fit and finish is flawless.

Making a vehicle as enormous as the Spectre look good is no mean feat, but Rolls has done a hell of a job, from most angles. The massive Pantheon Grille is something to behold in the metal, and because it doesn’t need to let air into an engine bay, it’s been designed for airflow, as has so much else. Rolls achieved a drag coefficient of 0.25, which is good for extending EV range, and they even spent more than 800 hours in a wind tunnel working on making the Spirt of Ecstasy hood ornament as aerodynamic as possible (she’s had her wings clipped, apparently).

The modern take on the classic grille combined with a chesty bonnet and very cool DRLs give the Spectre a look of classic modernity from the front, while the proportions over all give it a great side profile.

Apparently the design brief was based on some majestic cliffs, the Seven Sisters of Sussex, and the car definitely has that level of grandiosity.

The only weak point is the rear, which had to be sheer for aero reasons - and features the narrowest legally possible rear lights, which are supposed to look like “islands in a lake”, apparently. To me, driving behind one, the rear view is just a little dull.

The luscious interior is meant to be an example of “Automotive Haute Couture”, meaning hand made and stupidly expensive, and Rolls also humbly refers to it as a “cosseting art lounge”. It all sounds a bit over the top until you sit in it, and discover that it really does feel beyond special.

At surface level the GT 4-Door Coupe is a more liveable alternative to the GT Coupe, for blazing fast road trips, and obscenely rapid grocery runs. But the fact is it’s sooo much more practical than its two-door stablemate.

Space in the front is generous with storage running to twin cupholders in the centre console, as well as a modest glove box, decent sized door bins (with room for bottles), and a lidded storage box between the seats.

Connectivity and power options include 12-volt outlets, multiple USB ports and NFC (Near Field Communication) tech for easy Bluetooth and Wi-Fi connection of enabled devices.

Rear seat room is healthy. At 183cm I was able to sir behind the driver’s seat set to my position with plenty of leg and headroom to spare. Although anyone travelling in the rear centre position will have drawn the short straw, because the back seat is sculpted with bolstered positions for the two outer positions only.

A fold-down centre armrest offers more storage with a lidded box and a pair of cupholders and twin vents in the rear of the front centre console can be adjusted individually as part of the four-zone climate control system.

Hit the button, near the driver or on the key fob, to open the tailgate door and you’re presented with 461 litres (VDA) of cargo space, with the rear seat split-folding 40/20/40 to increase flexibility and liberate considerably more room.

There are tie-down hooks at each corner of the boot floor, an elasticised cargo net is included, and 12-volt power is provided.

Don’t bother looking for a spare wheel, the tyres are run-flats, and both GT 4-Door Coupe models are a towing no-go zone.

If you’re looking for the modern EV style interior, you can forget it, because Rolls says it didn’t want “any of that funky stuff” in the Spectre, so no giant screens in here. Indeed, I switched into a Rolls-Royce Ghost at one stage to be driven somewhere and the interior was almost exactly the same, although the new car gets a more modern fully digital dash. 

There’s plenty of room for water bottles and oddment storage and the sense of space for the driver and front passenger is suitably grand, but the rear seats are really for spoilt teenagers rather than Rolls owners. They’re not uncomfortable, at all, but they just feel a bit squeezed, you wouldn’t ask to be chauffeured in a Spectre, clearly it’s a Rolls you’d choose to drive yourself. 

The boot is wide, deep and long with a volume of 380 litres.

Australian pricing for the Rolls-Royce Spectre starts from $770,000 before on-road costs, and on the point of whether that represents value, well not to me, but certainly the huge number of orders Rolls claims to have been hit by suggests otherwise.

You do get a lot of car for your money, because the Spectre is vast and weighs almost three tonnes, and there’s no doubt that the interior is nicer than most people’s houses, or even the nicest hotel you’ve ever seen, and that the top-notch umbrellas hidden in each door are a nice touch.

One of the nifty and unexpected features the Spectre offers is a “Rolls-Royce Sound”, which you can toggle on and off. With the fake noise off, the car is freakishly quiet - apparently during testing they achieved a level of EV silence so incredible that people found it “disturbing” and had to engineer some sound back in - but with it on you get just the most subtle of guttural sounds. Every other company so far has gotten fake noise wrong, but Rolls has nailed it with the Spectre; it’s just loud enough, but suitably restrained as well.

You also get the wondrous Starlight Headliner, which uses optic fibre cables to paint the night sky on the roof, complete with shooting stars, and in the Spectre you can now have the stars fitted to the inside of its massive coach doors as well.

The V8 volcano generating this car’s prodigious power is the same all-alloy, direct-injected, 90-degree 4.0-litre (M178) unit used in the two-door GT coupe, in this case with dry rather than wet sump lubrication.

Its two turbos are located in the engine’s ‘hot vee’ to improve under-bonnet packaging and reduce the distance exhaust gas has to travel to reach each twin-scroll turbo, and that charged air has to travel to the cylinders (minimising throttle lag).

Maximum power of 470kW is available between 5500-6500rpm and peak torque of no less than 900Nm is delivered across a broad plateau from 2500-4500rpm.

The GT 53’s 3.0-litre in-line six-cylinder unit produces 320kW at 6100rpm and 520Nm from 1800-5800rpm, with an ‘EQ Boost’ starter-alternator unit between the engine and transmission adding an extra 16kW/250Nm.

Drive goes to all four wheels via a nine-speed automatic transmission, in the 63 S featuring a wet, multi-disc start-off clutch, and a conventional torque converter in the 53.

The ‘4Matic’ all-wheel drive system sends drive to the rear axle permanently, and the front wheels variably, with the torque split continuously adjusted according to conditions and driver input.

For the first time ever, this Rolls-Royce has no magnificent engine, no throbbing 12 cylinders, no, it has two separately excited synchronous motors, one on each axle for seamless all-wheel drive. The front motor makes 190kW and 365Nm while they’ve sensibly sent more grunt to the rear, which gets 360kW and 710Nm. Either motor on its own would be enough to power a normal car. The total figures are 430kW and 900Nm, which is supercar like.

The battery is made up 804 cells, weighs 700kg and has a net capacity of 102kWh, and the designers used it as a sound-deadening agent for road noise, because it’s so massive. 

The Spectre can hit 100km/h in 4.5 seconds, which feels very fast indeed when you’re piloting something that weighs 2890kg and is 5.5m long.

At the time of writing, Mercedes-Benz Australia hadn’t issued Australian Standard combined cycle fuel economy figures for the GT 4-Door Coupe, but NEDC Euro standard numbers are 9.4L/100km for the GT 53 and 11.3L/100km for the GT 63 S. NEDC CO2 emissions for the combined cycle are 215g/km and 257g/km respectively.

Despite the GT 63 S’s stop-start system (with glide mode) and eight- to four-cylinder deactivation tech (available from 1000-3250rpm), over close to 280km of mainly open road driving on the launch program we saw a dash-indicated figure of exactly 16.0L/100km.

Minimum fuel requirement for both models is 98 RON premium unleaded, and you’ll need 80 litres of it to fill the tank.

The Spectre is rated at 520km on the WLTP scale, but Rolls claims it can do a lot better (like 600km). Efficiency is claimed to be 21.5kWh per 100km.

We drove 210km and had 300km of indicated range left at the end, which is pretty close to the claim.

The Spectre can be charged at up to 200kW on a DC fast charger, on which it will take 35 minutes to go from 10 to 80 per cent charge.

On an 11kWh home system it will take 10 hours and 45 minutes to go from zero to 90 per cent charge.

Okay, so first up this is one fierce four-door, claimed to sprint from 0-100km/h in 3.2 seconds, which is properly supercar fast, and if you’re game and have a driveway long enough, able to blast up to a maximum velocity of 315km/h. Wow.

And behind the wheel it feels every bit of it. A flat-chat, launch-control assisted take-off narrowing your field of vision ever-so slightly and inducing an involuntary tensing of the abdomen.

The accompanying soundtrack is suitably ferocious, with a full-noise pass delivering a satisfyingly sharp spike on the decibel meter.

With 900Nm available from just 2500rpm there’s always an ocean of torque available, and by the time you’re into the upper rev range in anything above third gear you’re either headed for licence loss or the first corner of your favourite race circuit.

The nine-speed ‘MCT’ transmission in the 63 S features a (wet) take-off clutch and the big four-door puts its power down beautifully, the rear axle LSD and carefully tuned ‘4Matic’ all-wheel drive system seamlessly distributing torque between the axles and individual wheels able to make best use of it.

Slip into manual mode and the fun factor dials up a few notches with sharp and positive moves between ratios. But if you prefer leaving it in drive the transmission will sense what you’re up to and pick up ratios at just the right spot to keep things on the boil.

The electrically assisted steering delivers good road feel and the 63 S’s rear axle steering helps with precise and predictable turn-in on cornering.

The adaptive damping system helps keep this roughly 2.0-tonne weapon in check on twisting backroads, the optimal setting for our launch drive being engine, transmission, steering and exhaust turned up to 11, with the suspension in ‘Comfort’ mode. Spot-on.

A monster brake package comprises big ventilated discs (390mm fr / 360mm rr) with six-piston fixed calipers at the front and single-piston floating units at the rear. They wash off speed quickly and calmly time after time.

But dial things back to a less aggressive, more everyday mode and the ride comfort remains a stand-out trait. Even on big 21-inch rims the GT 63 S turns coarse-chip rural bitumen into a smooth carpet, with very little noise filtering into the cabin.

The front seats are super-supportive and comfortable for long stints behind the wheel and ergonomics are top-shelf with all major controls ideally placed and easy to use.

And if you want to get into the nitty gritty the AMG ‘Track Pace’ function in the Comand media system captures and analyses over 80 vehicle-specific data points as well as circuit lap times. Fun

The short answer to this question is that the Spectre drives just like a Rolls-Royce, but that answer is deceptively simple, because, for an electric vehicle, that’s actually a hell of an achievement.

Most EVs do not feel like cars to drive - the electric Hyundai Kona is not much like a petrol one at all - but what Rolls set out to do with its first EV was to make a vehicle that feels, handles and accelerates just like one of its famous and fabulously over-powered combustion-engined Ghosts, Phantoms or Wraiths.

This meant it had to be “Silent”, which it nails with ease - and the important thing to remember here is that even its V12 cars were always incredibly quiet, unless you really misbehaved. And it had to be “Effortless”, another brand pillar. Again, nailed it, because a Roller has never bothered with things like shift paddles, Sports modes or even the option to do anything but stick it in D for Drive and go. 

The sensation Rolls owners demand is endless, otiose acceleration, particularly off the line, and the Spectre delivers this in a typical EV fashion, but also one that’s very familiar to anyone who’s driven a Ghost, for example. It’s just a sense of overwhelming, prole-crushing progress, and it’s magnificent. 

The third and final brand pillar is “Waftability” and despite all the weight that it’s carrying (imagine how far over three tonnes this thing would have gone if they didn’t build their cars out of aluminium), the Spectre rides with a kind of hovercraft air of being just above, or barely in touch with, the ground. Bumps are no longer your concern, sir.

As mentioned, Rolls could have chosen a limousine-style vehicle as its first EV, but it has made a driver’s car instead - no CEO will sit in the back of a coupe like the Spectre. So it had to deliver when it comes to being fun, or at least a little frisky at times, when driven. 

Again, quite incredibly, despite its mass and weight, it does reward enthusiastic driving and can carve up even relatively narrow winding roads with aplomb, displaying very little body roll or pitching. The steering is almost absurdly light - because it must be “effortless” - but there’s still enough feedback to keep you interested. 

Most of the time, of course, the essentially laid back aura of being in a Rolls-Royce will seep into your body and brain and you will simply cruise along, patting yourself on the back for being so rich and clever.

And now, with an EV option finally available, you can tell yourself you’re saving the planet as well (as long as you don’t think about the 28 other cars in your garage).

The Spectre has not been crash tested for ANCAP. Its safety offerings include adaptive cruise control, lane-change assist, lane departure with active steer, a reversing assistant - "to support with parking and long reverses, eg country lanes or driveways, Spectre will reverse the previous 200m driven" - and collision warning with active braking.

Rolls tell us the Spectre has "Four airbags (does not need more)". So that's good news.

Mercedes-Benz covers its AMG range with a three year/unlimited km warranty, like the other two members of the German ‘Big Three’ (Audi and BMW) lagging the mainstream market where the majority of players are now at five years/unlimited km, with some at seven years.

On the upside, Mercedes-Benz Road Care assistance is included in the deal for three years.

Service is scheduled for 12 months/20,000km (whichever comes first) with pricing available on an ‘Up-front’ or ‘Pay-as-you-go’ basis.

For the GT 63 S pre-payment delivers a $1230 saving with the first three services set at a total of $6450, compared to $7150 PAYG. Fourth and fifth services are also available for pre-purchase.

Now, I would assume you'd get a lifetime warranty at Rolls prices, but apparently you get only four years, but it is unlimited mileage.

The Spectre's battery is covered by a 10-year warranty.

An extended service and warranty package is "TBC".

Rolls also offers 24/7 roadside assistance, and if your battery goes flat the company will take your Spectre to the nearest charging station.

A "regional flying doctor" is on standby 24/7 in extreme cases if Spectre “fails to proceed”.
