Mercedes-Benz E53 vs Maserati Granturismo

What's the difference?

As it turns out, the automotive world really doesn’t need an E63 S Coupe, because the E53 Coupe really does give you all you’ll ever need.

Simply put, the E53 Coupe’s balance of performance and luxury is bang on, while an E63 S Coupe would arguably prioritise one too much over the other.

Indeed, if you’re interested in a ‘relatively affordable’ grand-tourer that can get up and go when required, you could do a lot worse than the E53 Coupe.

From the most compelling engine sound this side of … well, anything … to a timeless, shapely body the GranTurismo is a surprising car. While its age is catching up to it in a few areas (fuel consumption, in-car entertainment) what matters most is that this Maserati still lights the fire in the belly.

The E53 Coupe already had an alluring exterior design, but in facelifted form, it looks even better.

The big changes are up front, where the E53 Coupe now has Mercedes-AMG’s signature Panamericana grille insert, with the multi-louvre aesthetic previously the reserve of its ‘63’ models.

In fact, the entire fascia has been redesigned, with the grille flipped upside down, while the Multibeam LED headlights are flatter and therefore angrier. Naturally, the bonnet and bumper have been tweaked to match, with the former featuring strong powerdomes.

Around the swoopy sides, a sporty set of black 20-inch alloy wheels is new, matching the window trim, while the only differences at the rear are the fresh graphics of the LED tail-lights.

Yep, the E53 Coupe still has a subtle bootlid spoiler and a prominent diffuser insert, which integrates the quad round tailpipes of its sports exhaust system.

Inside, the midlife facelift really makes itself known with its new flat-bottomed steering wheel with capacitive buttons and haptic feedback. This set-up is… fiddly, with presses often confused for swipes, so it's not exactly a step in the right direction.

And that’s particularly annoying because these controls are used for the carryover 12.3-inch touchscreen and 12.3-inch digital instrument cluster, which are now powered by Mercedes’ MBUX multimedia system, which bundles in Apple CarPlay and Android Auto support.

While now familiar, this set-up remains the benchmark in nearly all regards and is therefore a brilliant upgrade for the E53 Coupe, thanks to its speed and breadth of functionality and input methods, including always-on voice control and a touchpad.

Materials-wise, Nappa leather upholstery covers the seats and steering wheel as well as the armrests and door inserts, while Artico leatherette trims the upper dashboard and door shoulders.

Conversely, hard, shiny plastics adorn the lower door panels. Given that ‘cow hide’ and other soft-touch materials are used on most other surfaces, it’s unusual that Mercedes-AMG didn’t go the whole way.

Elsewhere, open-pore wood trim features prominently, while metallic accents brighten things up alongside the sporty stainless-steel pedals and smile-inducing ambient lighting.

As has already been (indelicately) mentioned, this is a design that is not only ageing well, it still looks pretty fresh from most angles. The only let down are the over-sized tail-lights that look more at home on something less exotic. Those aside, it's a deeply pretty car, with lovely surfacing, the highlight being those beautiful rising guards that funnel your vision down the bonnet.

Interior packaging isn't the GT’s strong point. Inside is pretty cosy with a fat transmission tunnel that makes for a narrow footwell.

With the Sport you get carbon-backed seats that are thinner in the backrest allowing for more room in the tight rear bucket. Snug they may be, but head and leg room is surprisingly good. The white leather interior of this one may not have been to everyone’s taste, but it was certainly beautifully put together.

The boot is fairly small but will fit more than, say, the similarly sized (but double the price) Ferrari FF.

The GranTurismo MC Sport comes in two versions. Both have six-speed gearboxes, but one has the rear-mounted robotised manual while our version was the six-speed ZF automatic, which is mated directly to the engine.

The auto weighs in at $295,000, $23,000 cheaper than the Stradale. Both cars come standard with Poltrona Frau leather, carbon fibre trim inside and out, alloy pedals, bi-xenon headlights, foglights, parking sensors front and rear, 20-inch MSC alloys, keyless entry, electric seats, Alcantara headlining, cruise control, dual-zone climate control and electric adjustment for the steering wheel.

Sadly, time has marched on from when the GranTurismo's entertainment system was first presented to the world. It's a weird, unwieldy system that takes a lot of getting used to, with buttons that don't always seem to do what their label says. Pairing the phone was arduous and while most owners do that once, it does speak to the overall usability.

Having said that, the 11-speaker Bose stereo pumped out some pretty good sound and once the satnav's input method is deciphered, it worked surprisingly well given its fairly basic presentation on the seven-inch screen.

The E53 Coupe is powered by a 3.0-litre inline six-cylinder petrol engine that produces a hearty 320kW of power at 6100rpm and 520Nm of torque from 1800-5800rpm.

The unit in question has one traditional turbocharger and an electric-powered compressor (EPC), which is available at engine speeds up to 3000rpm and can spool up to 70,000rpm in just 0.3 seconds for instantaneous punch.

But that’s not all, because the E53 Coupe also has a 48V mild-hybrid system called EQ Boost. As its name suggests, it has an integrated starter-generator (ISG) that can provide up to 16kW and 250Nm of temporary electric boost.

Mated to a nine-speed torque-converter automatic transmission with redesigned paddle-shifters, and Mercedes-AMG’s fully variable 4Matic+ all-wheel-drive system, the E53 Coupe sprints from a standstill to 100km/h in a handy 4.4 seconds.

Maserati's 4.7L V8, inherited from the then-parent Ferrari, is a cracker. Based on the V8 found in the F430, it has a gloriously silly redline of 8000rpm. Peak power is 338kW at 7000rpm and 520Nm at 4750rpm.

The 0-100km/h is dispatched in 4.8 seconds and top speed is 298km/h.

The transmission is a six-speed ZF automatic and fuel economy is a sobering 14.3L/100km on the combined cycle.

If an E53 Coupe was your daily driver, you’d be very happy, because its balance of comfort and performance is just about as good as it gets.

Stick the boot in and the engine responds with a level of enthusiasm that only electrification can provide. Not only does the ISG provide timely thrust, but the EPC helps the E53 Coupe reach its maximum torque, although it has to work harder for peak power.

That said, despite the addition of the EQ Boost system and the EPC, the E53 Coupe still feels like a proper Mercedes-AMG model, staying true to the high-performance mantra while offering a different approach.

Critically, all the drama is there, as it charges towards the horizon with intent as the transmission swaps gears smoothly, providing relatively quick shifts and revving on the down changes when required. It all adds up to a properly exciting drive.

However, it’s the E53 Coupe’s sports exhaust system that’s likely to command all the attention with its crackles, pops and overall booming soundtrack in the Sport mode. It can also be manually engaged in any mode by pressing a button in the centre console.

And given the E53 Coupe’s 4Matic+ system is fully variable, it offers plenty of grip when briskly accelerating and enjoying the soundtrack, but its rear end can still step out briefly when cornering hard.

Speaking of handling, the E53 Coupe goes around corners surprisingly well, defying its large dimensions and considerable 2021kg kerb weight by exhibiting strong body control.

Coming into bends, the E53 Coupe can also lean on its sports brakes, which pull up with absolute confidence.

And when you’re guiding the E53 Coupe through the twisty stuff, the electric power steering comes to the fore, with its speed-sensitivity and variable ratio.

The steering set-up is somewhat disappointing at times, however, with the feedback not quite up to the level of a proper performance car.

That said, it is quite direct and feels meaty in hand – two traits that are necessary for success – with this heft increased in the Sport drive mode. Comfort is where it’s at, though, if you ask me.

That said, the E53 Coupe’s suspension uses air springs and adaptive dampers to make it a comfortable cruiser.

Sure, this set-up’s tune does prove to be a little firm on lower-quality country roads, with most bumps and lumps felt by occupants, but on well-maintained highways and city roads, it’s got suitable levels of smoothness.

In keeping with this luxurious feel, the E53 Coupe’s Noise, Vibration and Harshness (NVH) levels are pretty damn good, with tyre roar and wind whistle easily missed while enjoying its aforementioned Burmester sound system.

There are few more impressive sounds in the automotive world than a Maserati-tuned V8. Even on start-up, the smooth V8 gives you a little bellow to wake the neighbours and when in non-Sport mode it quickly settles into a quiet idle. The exhaust has the now-familiar valving that opens up when you switch it into Sport and if you don’t default to that when driving the GT, you're probably dead inside.

The V8 makes a tremendously addictive racket, getting better with every rev as the tacho needle swipes right to the redline.

When compared with the lightweight sportster from which the engine is lifted, you won't be moving quite as quickly, but the noise and the sharp-shifting transmission will keep you happy. Tunnels are worth the price of entry as you crank the windows down and flip the paddles to find second or even first.

It's hard to pick that the transmission is a traditional automatic. The shifts are fast and positive but never violent – that would be out of character – responding properly to the paddles. In automatic, it's smooth and gentle.

The steering is mighty impressive too. There's enough feel to keep you interested and entertained but not so much you’ll be overwhelmed in the daily drive. The nose changes direction with a flick of the wrists and the moderately-firm Skyhook suspension does a good job of making the rest of the car follow without undue body roll.

Despite rolling on 20-inch alloys shod with sticky 245s up front and 285 at the rear, cruising in the GT is surprisingly quiet and comfortable. WithSport mode off, it's a very agreeable place to be. The seats are hugely comfortable, even in the rear, which seems impossible.

The MC comes standard with six airbags, ABS, stability and traction controls, pre-tensioned and load-limited seatbelts front and rear.

There is no ANCAP safety rating for the GranTurismo.
