Porsche 718 vs Mercedes-Benz E53

What's the difference?

The 718 Cayman Style Edition only costs a bit more than the entry-grade Cayman it's based on, but opens up more special colours and contrasting features from the wheels to decals, even leather upholstery. The value is good, the look is enhanced and the car remains superb to drive on the right roads.

Living with a Cayman daily is ‘do-able’ but you’ll have to be understanding given it's not the most user-friendly car to drive, and then there’s the low-level safety tech.

But in return, you’ll own one of the best and relatively affordable prestige sports cars ever made and one of the last of the combustion-powered Porsche Caymans.

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.

The 718 Cayman is often labelled as the 'junior 911' but that downplays its status as an outstanding sports car in its own right.

It’s not a smaller version of the 911, at all, but it is smaller than a 911. Not by much, though. The Cayman is 140mm shorter in length than the 911 at 4379mm end-to-end. Interestingly, the Cayman has a longer wheelbase at 2475mm and is taller at 1295mm.

The 718 Cayman is beginning to date in its design with this generation of the sports car arriving eight years ago. From the outside it’s holding up well in terms of styling , but inside it feels very 2016 with the small media screen and analogue dials.

It gives me a weird nostalgic feeling I normally only get driving older cars, but in a current model. Which could be why Porsche is jazzing the Cayman up with this Style Edition.

The Style Edition enhances the look of the entry-grade Cayman with 20-inch 718 'Spyder' wheels in a high gloss black or white finish, and there’s a choice of six special colours ranging from the Crayon hue our car wore to 'Ruby Star Neo', 'Shark Blue', 'Carmine Red' and 'Arctic Grey'.

The Style Edition also adds black sport tailpipes, full-colour Porsche crests on the wheel hub covers, a black leather interior with contrasting Crayon stitching, Porsche crest embossed headrests, illuminated door sills and floor mats with Crayon contrast stitching.  

Buyers can also choose a 'Contrast Package' in black or white which adds Porsche lettering to the side of the car and a strip to the bonnet.

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.

The 718 Cayman doesn’t have back seats -  it's a two-seater sports car. Cabin storage is almost non-existent but is saved by a glove box and pull-out door pockets which are bigger than they look.

Surprisingly, there are three cupholders - two which pop out of the dashboard above the glove box and another in the small centre console bin.

Cargo space isn’t bad for a two-seater sports car with 184-litre rear boot and a front boot with a 150-litre capacity. That’s roughly one nine-year old child as you can see from the photos. My son wanted to sit in there, which I agreed to, but I said no when he asked me to shut the bonnet.

Measuring 4835mm long (with a 2873mm wheelbase), 1860mm wide and 1430mm tall, the E53 Coupe is a genuinely large car, which is great news for practicality.

The boot has a pleasing cargo capacity of 425L, but it can be increased to an undisclosed volume by stowing the 40/20/40 split-fold rear bench via the handy manual release latches.

It’s worth noting that while the aperture is wide, it’s not tall, which could be a problem for bulkier items alongside the tall load lip, although two tie-down points are on hand for securing loose items.

However, what really impresses is the amount of space inside. While the front sports seats are comfortable, the two rear passengers are in for the bigger treat, with room plentiful, mercifully ending the argument of who gets stuck in the uncomfortable second row.

Behind our 184cm driving position, there’s two inches of legroom as well as an inch of headroom, although toe-room is almost non-existent.

Being a four-seater, the E53 Coupe divides its rear occupants with a tray that contains two cupholders, while they also have access to two side cubbies and a small central cubby with two USB-C ports. This cubby is positioned between the air vents at the rear of the centre console.

And yes, even child seats can be fitted, with two ISOFIX and two top-tether anchorage points available should they be required. In fact, the long front doors make this task less challenging, although those big doors do become problematic in tight carparks.

All of that’s not to say occupants in the first row aren’t treated well, because they are, with the centre console’s cubby featuring two cupholders, a wireless smartphone charger, a USB-C port and a 12V power outlet.

Other storage options include the decently sized central bin, which contains another two USB-C ports, while the glovebox is also of a decent size, and then there’s the overhead sunglasses holder.

Priced from $164,800 plus on-road costs, the facelifted E53 Coupe is actually a staggering $14,465 more affordable than its predecessor.

But if you’re not a fan of its body-style, the $162,300 E53 sedan (-$11,135) and $173,400 E53 Cabriolet (-$14,835) are also available.

Either way, standard equipment not already mentioned includes metallic paintwork, dusk-sensing lights, rain-sensing wipers, power-folding side mirrors with heating, keyless entry, rear privacy glass and a power-operated bootlid.

Inside, push-button start, a panoramic sunroof, satellite navigation with live traffic, digital radio, a 590W Burmester surround-sound system with 13 speakers, an augmented reality (AR) head-up display, a power-adjustable steering column, power-adjustable front seats with heating, dual-zone climate control and an auto-dimming rearview-mirror feature.

Direct rivals for the E53 Coupe are non-existent, with the closest being the smaller – and therefore much more affordable – BMW M440i Coupe ($118,900) and Audi S5 Coupe ($106,500). Yep, it’s a unique offering on the market, this Merc.

So, under the bonnet of a Cayman is the front boot, but if it’s the engine you’re after you’ll need to go through the rear hatch because this is a mid-engined car.

Getting to the engine means removing several fixtures and covers which begins to feel like you’re dissembling the vehicle and comes with a rising anxiety that it all won’t go back together.

But it all clicks back in. It’s just a slow and tedious process. Fortunately, oil and water can be added by removing the circular covers you can see in the images. 

Under the layers of covers, deep down just in front of the rear axle, is the Cayman’s 2.0-litre ‘flat’ four-cylinder turbo-petrol engine which makes 220kW and 380Nm. A seven-speed dual-clutch automatic transmission sends drive to the rear wheels. 

It’s not a huge amount of power but the Cayman only weighs 1365kg and so can get from 0-100km/h in 5.1 seconds. Not brutally quick but the way this car handles is what you’ll like.  

Oh, and just to be clear, the Style Edition doesn’t bring any extra power or engine changes. The outputs and performance are the same as the entry-grade Cayman.

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.

Porsche says that after a combination of open and urban roads the Cayman’s fuel consumption should be 7.0L/100km. My 143km fuel test, taking in country roads and school runs, used 21.8L of petrol and equates to 15.2L/100km. Which means I had about twice as much fun as Porsche did when it recorded its fuel consumption.

The 64-litre tanks means in theory you should be able to travel 914km between fills if you’re conservative with fuel.

The E53 Coupe’s fuel consumption on the combined-cycle test (ADR 81/02) is 9.3L/100km, while its carbon dioxide (CO2) emissions are 211g/km.

Given the performance on offer, both claims are pretty good. And they’re made possible by the E53 Coupe’s 48V EQ Boost mild-hybrid system, which has coasting and extended idle-stop functionality.

That said, in our real-world testing, we averaged a more realistic 12.2L/100km over 146km of driving, although the launch test route only involved high-speed country roads, so expect a higher result in metropolitan areas.

For reference, the E53 Coupe has a 66L fuel tank, and it will only drink more expensive 98RON premium petrol.

The 718 Cayman Style Edition doesn’t come with any performance advantages over the already brilliant entry-grade Cayman it’s based on. And it is brilliant to drive. Several big steps above Audi’s TT, Nissan's Z or Toyota and BMW’s Supra/Z4 'twins under the skin' in terms of handling, steering and engagement. 

That said, the Cayman isn’t as easy to drive as any of those cars. The steering is heavy, the accelerator is stiff, the dual-clutch auto transmission feels a bit rough and the turbo lags, then sends in the mumbo a bit too fast and too late. Oh, and and the seats are a tad tight.

But I can overlook all of this because on good winding country roads the Cayman feels like a water drop running down a wall, moving naturally and harmoniously around whatever it encounters.

The day-to-day school runs and grocery getting isn’t quite as poetic, and a Cayman proves challenging in the real world over potholes and in supermarket car parks. You’d have to love the Cayman for better or worse, as many do, to live with it daily. If you can't, there's the Audi TT.

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.

ANCAP awarded the fifth-generation E-Class sedan and Estate its maximum five-star rating in 2016, although it doesn’t apply to the E53 Coupe, due to its differing body-style.

That said, advanced driver-assist systems still extend to autonomous emergency braking with pedestrian detection, lane-keep and steering assist (including emergency), adaptive cruise control with stop and go functionality, traffic-sign recognition, driver-attention alert, high-beam assist, active blind-spot monitoring and cross-traffic alert, tyre-pressure monitoring, park assist, surround-view cameras and front and rear parking sensors.

Other standard safety equipment includes nine airbags, anti-skid brakes and the usual electronic traction and stability-control systems.

The Cayman Style Edition is covered by a three-year/unlimited kilometre warranty and servicing is needed every 12 months or 20,000km.

With Porsche, final service costs are determined at the dealer level (in line with variable labour rates by state/territory).

We'd like to see the warranty coverage increased to five years/unlimited kilometres which will bring it in line with more mainstream brands.

Like all Mercedes-AMG models, the E53 Coupe comes with a five-year/unlimited-kilometre warranty, which is currently the benchmark in the premium market. It also comes with five years of roadside assistance.

Better yet, the E53 Coupe’s service intervals are rather long, at every year or 25,000km – whichever comes first.

It’s also available with a five-year/125,000km capped-price-servicing plan, but it costs an expensive $5100 in total, or an average of $1020 per visit, with the E53 Coupe’s fifth trip charging $1700 alone. Ouch.
