Porsche Taycan vs Mercedes-AMG E63

What's the difference?

Porsche says its Taycan models have always been performance-focused and this updated version is even faster than the car it replaces, in a straight line and point-to-point. It’s better equipped, more efficient, and yes, more expensive but every millimetre a Porsche in the way this EV sedan and wagon package has been executed.

It’s an impressive car likely to appeal to Porsche newcomers rather than traditionalists, although you may already have other Porsches in the garage. But with the Macan EV landing any minute and the pure-electric 718 Boxster and Cayman just around the corner it's a key part of the changing face of this iconic German brand.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

The E 63 S fills its niche in AMG's Australian line-up perfectly. More mature than the brand's four-cylinder hatches and SUVs, but not as overbearing as some of its bigger sedan, GT and SUV stablemates. And its ability to seamlessly switch between serene comfort and dynamic performance has nailed the objective for this 2021 update.

Porsche has freshened up the Taycan’s front and rear end, the nose losing the vents dropping down from the headlights as previewed by the original Mission E Concept in 2015.

Matrix LED headlights are standard with high-resolution HD available. But there are no major sheet metal changes to the bulk of the car. And why would you fiddle with it? The drag coefficient is an ultra-slippery 0.22.

Around the back the Porsche logo in the rear light strip has been given a cool three-dimensional treatment al la the 911, Panamera and other current Porsches. And if you have eyes for the Turbo or Turbo S the brand’s glamorous ‘Turbonite’ metallic silver colour is now available.

Inside is a screen-rich environment with a three-dial digital version of the brand’s five-dial instrument cluster customisable through roughly 5000 configurations and there’s a new multimedia software interface for the central screens with additional functions. A passenger display is a $2860 option.

The E 63 S has been massaged for 2021 starting with flatter headlights, AMG's now signature 'Panamericana' grille, and a high gloss black flap across the top of the curved 'Jet Wing' section defining the lower part of the nose.

At the same time, the vents on either end of it are larger and feature twin transverse louvers to guide cooling air to wherever it's needed.

It's all about what AMG calls 'optimised aerobalance' but the form is just as appealing as the function. The characteristic 'Power Domes' in the bonnet dial up the muscle, as do the fat wheel arches (+27mm each side), and 20-inch rims with distinctive aero inserts.

This car's optional exterior carbon package consists of a front splitter, side sills, a flash near the fender badges, the exterior mirror covers, the boot lid lip spoiler, as well as the lower apron around the redesigned diffuser and quad tailpipes.

New, intricately styled LED tail-lights are also flatter, but there's even more going on inside.

A new AMG sports steering wheel features three rounded twin-spokes with new switches on the bottom to control the car's dynamic set-up.

It also picks up a new take on the small touch-sensitive controllers used to adjust the instrumentation and manage other functions like phone calls, audio and the cruise control.

Not sure I'm in love with them at this stage. In fact, the words fiddly, imprecise, and frustrating come to mind.

Nappa leather covering the superb AMG sports seats, upper dash, and door beltlines remains standard, but the show-stopper is the 'Widescreen Cockpit' - twin 12.25-inch digital screens for the MBUX multimedia interface on the left and instruments on the right.

The instrument cluster can be set to 'Modern Classic', 'Sport' and 'Supersport' displays, with specific AMG read-outs such as engine data, gear speed indicator, warm-up status, car set-up, as well as a G-meter and 'RaceTimer.'

To borrow an official automotive design term, it looks schmick. Overall, with touches like open-pore black ash wood trim, and brushed metal highlights, the interior looks efficient but classy, with an obvious attention to detail in the layout and its execution.

At nearly 5.0m long and 2.0m wide but less than 1.4m tall the Taycan is a low-slung large sedan.

In the front of the Taycan I’ve got plenty of breathing space, lots of headroom and enough shoulder room and you don’t feel cramped relative to the co-pilot.

In terms of storage, there are pockets in the doors with room for bottles, a couple of cup and bottle holders in the centre console as well as a tray under the flying buttress type upper console section.

A lidded box between the seats housing a couple of USB-C outlets and a 12-volt socket is handy and there’s a decent-size glove box on the passenger side. 

Interestingly, an in-car video function enables video streaming on the central display (while the vehicle is stationary) and the passenger display at any time with the vision hidden from the driver by a lenticular-style screen.

In the back, sitting behind the driver’s seat, set for my 183cm position, I have ample legroom and space for my feet. Problem is my head hits the roof solidly, even with the extra room afforded by the panoramic glass insert, which is a no-cost option from the Taycan 4S up.

Standard configuration is two rear seat positions, although a ‘4+1’ set up which adds an occasional centre rear position is optionally available. Trust me, that’s tight. 

On the upside you have adjustable ventilation for the rear seat passengers (climate control zones on the Turbo grades) with a small oddments shelf below them, slots in the doors for bottles and two more cup or bottle holders in the fold-down centre armrest.

No map pockets on the front seat backs, so while there’s some room for storage it’s not exactly over supplied in that department, or for breathing space in general.

Boot space is relatively modest at 366 litres in the sedan but the 60/40 split-folding rear seat liberates more space if required. The Cross Turismo wagon offers 405 litres and a much larger load aperture for greater flexibility. An 84L frunk sits in the nose of all Taycans.  

Interesting to note Taycans in other markets boast an extra 41L of boot space. It doesn’t feature here because Porsche Australia has made the high-end Bose sound system standard and its sub-woofer eats into available capacity. 

A power boot lid or tailgate and auto self-levelling to maintain the car’s ride height under load is standard but there’s no spare tyre of any description. A repair/inflator kit is your only option, which is less than ideal.

At just under 5.0m end-to-end the E-Class sits in the upper range of the mid-size luxury spectrum. And almost 3.0m of that is accounted for by the distance between the axles, so there's plenty of space inside.

The driver and front passenger are provided with heaps of room to breathe, and there's a surprising amount of space for those in the back as well.

Sitting behind the driver's seat set for my 183cm (6'0”) position I had more than adequate head and legroom. But access to and from the back is a struggle for full-size adults.

The rear doors open out a long way, but the limiting factor is the size of the aperture, necessitating excessive contortion of the head and limbs to fold in and out of the car.

Connectivity runs to two (power-only) USB-C sockets in the front centre storage bin, as well as another USB-C (for power and multimedia) and 12-volt power outlet in the centre console.

Speaking of the front centre storage bin, it's a decent size and has a padded split lid so it can double as an armrest. There are two cupholders in the front console, a generous glove box, as well as long door compartments with recesses for large bottles provided.

There's a pair of USB-Cs along with another 12-volt socket in the back, sitting under the climate control panel with adjustable vents in the rear of the front centre console. Nice.

The fold down centre armrest incorporates a lidded (and lined) storage box as well as two pop-out cupholders. Again, there are bins in the doors with room for smaller bottles.

The boot offers 540 litres (VDA) of volume, and is able to swallow our three-piece hard suitcase set (124L, 95L, 36L) with room to spare, or the substantial CarsGuide pram, or the largest suitcase and pram combined! There are tie-down hooks to help secure loads, too.

Don't bother looking for a spare of any description, a repair/inflator kit is your only option. And the E 63 S is a no-tow zone.

So, first of all, let's get the price out of the way. At $253,900, before on-road costs, this car's competitive set is a bruising, all-German trio comprising the Audi RS 7 Sportback ($224,000), BMW M5 Competition ($244,900), and Porsche Panamera GTS ($309,500).

And no surprise, it's loaded with all the luxury features you'd expect in this part of the market. Here are the highlights.

On top of the standard performance tech and safety equipment fitted to the E 63 S (covered later in this review), you'll also find: Nappa leather trim (seats, upper dash, upper door cards, and steering wheel), MBUX multimedia (with touchscreen, touchpad, and 'Hey Mercedes' voice control), 20-inch alloys, three-zone climate-control, interior ambient lighting, auto LED headlights (with 'Active High Beam Assist Plus'), eight “energising comfort programs” (with 'Energising Coach'), an 'Active Multicontour' front seat package, the 'Air Balance' package (including ionisation), and keyless entry and start.

Also included are the the 'Widescreen' digital cockpit (twin 12.25-inch digital screens), 13-speaker Burmester audio with digital radio, Apple CarPlay and Android Auto, a panoramic sunroof, adaptive cruise control, a head-up display, augmented reality satellite navigation, 'Parktronic' self-parking, electric front seats, seat cooling and heating front (heated rear), heated front centre armrest, a power-adjustable steering column, auto rain-sensing wipers, a wireless device charger, illuminated door sills, as well Amazon Alexa, etc, etc, etc.

And our test car also featured a couple of tasty options. An exterior carbon package ($7500), and AMG's professional grade ceramic composite brakes ($15,900), for an as-tested price of $277,300.

The entry-level single-motor RWD Taycan features a new electric motor that’s 10kg lighter and seven per cent more powerful but more notably produces 22 per cent more torque than the unit it replaces.

Both it and the additional motor fitted to the front axle of AWD models are permanent magnet synchronous units with outputs up across the range, the Turbo S producing a stonking 700kW and more than 1100Nm.

That 700kW peak number for the Turbo S comes courtesy of an ‘overboost’ function with Launch Control. And Taycan models equipped with the Sport Chrono package and the Performance Battery Plus have up to an extra 70kW courtesy of a 10sec push-to-pass button.

There’s a two-speed transmission on the rear axle and a single-speed on the front of AWD variants.

The E 63 S is powered by the M178 version of the all-alloy 4.0-litre twin-turbo V8 engine used across numerous AMG models from the C-Class up.

Thanks in no small part to direct injection and a pair of twin-scroll turbos (located in the engine's 'hot vee' to optimise throttle response), this all-alloy unit produces 450kW (that's 612hp) from 5750-6500rpm, and 850Nm from 2500-4500rpm.

And as per standard AMG practice for its Vee engines, this car's powerplant was built from scratch by a single engineer in Affalterbach. Thank you Robin Jäger.

AMG calls the nine-speed transmission used in the E 63 S an MCT, which stands for Multi-Clutch Technology. But it's not a dual-clutch, rather a normal auto transmission using a wet clutch as opposed to a conventional torque converter, to connect it to the engine on take-off.

Drive goes to all four wheels via Merc's '4Matic+' AWD system, built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.

The Taycan runs 800-volt electric architecture which means it can charge at up to 320kW on a DC fast-charger which is 50kW more than its predecessor. In fact, charging at more than 300kW for up to five minutes is possible. 

You’re looking at a 10-80 per cent charge in 18min on a fast charger which is down from 37min. It’s 46min on a more typical 120kW charger.

An 89kWh lithium-ion battery is standard on the entry-grade Taycan. It boasts a nickel, cobalt, manganese cell chemistry which Porsche says delivers high energy content, lower internal resistance and higher charge and discharge currents. And it’s 9.0kg lighter.

All models above it feature the 105kWh ‘Performance Battery Plus’, a roughly $12K option on the base car.

Maximum AC charging capacity is 11kW and you’re staring down the barrel of nine hours for a 0-100 per cent fill of the smaller battery and 11 hours for the performance battery pack.

Official energy consumption on a combined urban, extra-urban cycle varies from 17.1kWh/100km for the single motor Taycan to 17.8kWh for dual-motor variants.

On the launch drive program, covering mainly rural B-roads on Tasmania’s east coast, we cycled through all models on offer and recorded a best figure of 21.5kWh/100km for the single-motor Taycan up to 22.0kWh for the Turbo S. Not bad.

Claimed range is 566km for the entry-grade Taycan, up to 626km for dual-motor models.

Interestingly, on 4WD models the - front electric motor can electronically decouple more frequently to improve efficiency.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 12.3L/100km, the E 63 S emitting 280g/km of CO2 in the process.

That's a pretty hefty number, but in line with this car's proportions and performance potential.

And Merc-AMG has gone to great lengths to minimise fuel use. As well as the standard 'Eco' stop-start function, in the 'Comfort' drive program cylinder deactivation becomes active, the system able to drop four cylinders anywhere between 1000 to 3250rpm.

There's no physical hint of half the cylinders leaving the party. The only clue is a blue icon on the dash indicating a temporary shift to V4 operation.

Despite all that effort, however, we saw a dash-indicated 17.9L/100km over a mix of urban trundling, highway cruising, and some spirited dynamic assessment.

Recommended fuel is 98 RON premium unleaded (although it'll run on 95 at a pinch), and you'll need 80 litres of it to fill the tank. That capacity translates to a range of 650km according to the factory claim, and 447km using our real world result.

Full disclosure. My preference when it comes to Porsche propulsion is pistons in cylinders; ideally six of them, horizontally opposed. 

But if the Taycan is on your shortlist you’re ready to move past internal combustion and there is no doubt this car is properly quick. 

The entry-level RWD model accelerates from 0-100km/h in 4.8sec (0.6 faster than the outgoing model) with the Taycan Turbo S at 2.4sec which is hypercar fast.

Porsche admits to having played around with some dual-clutch transmission-type mimicry along the lines of the Hyundai Ioniq 5 N. But the boffins in Zuffenhausen left that to one side due to concerns over compromise to the car’s point-to-point ability. Porsche seemingly can’t entertain anything that makes a car slower.

It did, however, install a push-to-pass function on dual-motor versions which gives you a 10-second burst of extra performance which is fun.

Suspension is by forged alloy double-wishbone front and rear with some extra links at the back.

Adaptive air suspension is standard across the range, and ‘Active Ride’ is fitted to the upper variants which takes things one step further.

And it does ride very nicely. The launch drive covered second-class, coarse-chip B-road type surfaces and the Taycan smooths the road out beautifully.

Standard wheel diameter is 19-inch for the entry-grade, 20s for the 4S and Turbo, then 21s on the Turbo S. The cars on the launch program all featured 21-inch rims shod with Goodyear Eagle F1 or Michelin Pilot Sport 4 rubber and even on those big wheels the car still rides well.

In terms of the steering… hey, it’s a Porsche. It’s fantastic. Accurate and direct without being too jerky or snappy. It does exactly what you want the car to do. The connection with the front tyres feels like it’s almost direct.

This car may be lighter than its predecessor but all models are over 2.0 tonnes so you’d expect it to be heavy and slow. It’s not. Point and accelerate through corners with supreme confidence. It’s beautifully balanced. What you’d expect from a Porsche performance car.

Physical braking is by big ventilated discs all around with six-piston aluminium monobloc fixed-calipers at the front and four-piston units at the rear. Suffice it to say they wash off speed effectively. 

Believe it or not the Turbo S’s front brake calipers contain no less than 10 pistons, clamping ceramic composite rotors. We gave all Taycan variants a solid workout on the Baskerville Raceway just north of Hobart and stopping power felt as strong and effective at the end of the session as it did at the start.

There’s also improved recuperation capacity for the regenerative braking system, up 30 per cent from 290 to 400kW.

In terms of miscellaneous observations, beware the 11.7m turning circle. What might appear to be a three-point turn situation often turns into a five-pointer.

And entry to cars fitted with Active Ride is made easier (when activated). As soon as a door is opened, the body raises by 55mm. May seem OTT but it makes life with the Taycan that bit better.

AMG's major goal with this upgrade of the E 63 S was to maintain its dynamic response and ferocious performance, but dial in the extra comfort customers had said they wanted.

So, the 4Matic+ AWD system has been fine-tuned for more smoothness as has the Comfort option in the dynamic set-up. But we'll investigate that shortly.

First, that 4.0-litre turbo V8 in the nose is claimed to slingshot this roughly 2.0-tonne sedan from 0-100km/h in just 3.4 seconds, and it feels every bit that fast.

With 850Nm available from 2500-4500rpm and nine gear ratios to help keep you operating in that Goldilocks band, mid-range thrust is monumental. And thanks to the bi-modal sports exhaust it sounds beautifully brutal.

The nine-speed auto's wet clutch, as opposed to a conventional torque converter, is designed to save weight and optimise response. And while some will tell you an auto with one input shaft is never going to be as fast as a dual-clutch with two, shifts are rapid and direct. The wheel-mounted shift paddles are larger and set lower, as well.

The AMG 'Ride Control+' suspension with multi-chamber air suspension and adaptive damping is amazingly good. The underlying set-up is by multi-links front and rear, and despite riding on big 20-inch rims wrapped with low-profile, high-performance Pirelli P Zero rubber (265/35 fr - 295/30 rr) the Comfort setting is incredibly... comfortable.

Slip into 'Sport' or 'Sport+' and the car immediately feels tauter but far less compliant and forgiving. An impression reinforced by the engine, transmission, and steering shifting to a more buttoned-down mode at the same time.

The standard dynamic engine mounts play a big part here. Able to make a soft connection for maximum comfort, but switch to a rigid link when required.

But no matter which mode you're in, the car is well damped and feels beautifully balanced in quick cornering. And the E 63 S's electro-mechanically-assisted variable-rate steering is progressive, feelsome, and accurate.

The 4Matic+ AWD system is built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.

Torque distribution happens imperceptibly, the big V8 putting its power down emphatically, with various electronic systems tieing up the loose ends as you aim up for the next corner.

 There's even a 100 per cent RWD Drift mode available in the Race setting, but without a race circuit at our disposal this time around that'll have to wait for another time.

The optional ceramic brakes feature huge rotors and six-piston front calipers, and stopping power is immense. And the good news is they operate quickly but progressively at normal pottering around town speeds. No warming up required to get them in an optimal temperature zone (as can be the case with other ceramic set-ups).

The three-pointed star's white-coated boffins have gone to town on the E 63 S, and the car is as good as it currently gets in terms of active and passive safety technology.

You could argue this car's dynamic ability is its strongest contributor to crash-avoidance. But a broad suite of features, specifically designed to keep you out of trouble includes, forward and reverse AEB (with pedestrian, cyclist, and cross-traffic detection), traffic sign recognition, 'Attention Assist', 'Active Blind Spot Assist', 'Active Distance Assist', 'Active High Beam Assist Plus', 'Active Lane Change Assist', 'Active Lane Keeping Assist', and 'Evasive Steering Assist.' That's a lot of assists.

There's also a tyre pressure monitoring and pressure loss warning system, as well as a brake priming function (monitors release speed on the accelerator pedal, moving pads factionally closer to the discs when required), and brake drying (when the windscreen wipers are active the system periodically applies just enough brake pressure to wipe water off the brake rotors to optimise wet weather efficiency).

But if an impact is unavoidable the 'Pre-Safe Plus' system is able to recognise an imminent rear-end collision and fire up the rear hazard lights (at high frequency) to warn following traffic. It will also firmly apply the brakes once the vehicle is stationary to minimise the risk of whiplash injuries if the car's then hit from behind.

If the potential crash is coming from the side, 'Pre-Safe Impulse' inflates air chambers in the side bolsters of the front seat backrest (within a fraction of a second) moving the occupant to the side towards the centre of the car, away from the impact area. Amazing.

As well as that, there's an active bonnet to minimise pedestrian injuries, an auto emergency call function, 'Crash Response Emergency Lighting', even a first aid kit and hi-vis vests for all occupants.

For the record, the current E-Class received a maximum five-star ANCAP assessment in 2016.

Porsche covers the Taycan with a three-year, unlimited km warranty which is off the pace for the premium segment where five years, unlimited km is the norm. The high-voltage drive battery is covered by an eight-year, 160,000km warranty. The paint is covered for three years and a 12-year (unlimited km) anti-corrosion warranty is included.

Porsche Roadside Assist provides 24/7/365 coverage for the life of the warranty, and after the warranty runs out is renewed for 12 months every time the vehicle is serviced at an authorised Porsche dealer.

Thanks to fewer moving parts, servicing intervals for the Taycan are relatively lengthy at two years or 30,000km, whichever comes first. 

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

All AMG models sold in Australia are covered by Mercedes-Benz's five year/unlimited km warranty, with 24-hour roadside and accident assistance included for the duration.

Recommended service interval is 12 months or 20,000km, with pricing for a three-year (pre-paid) plan set at $4300, a $950 saving overall relative to its three year, pay-as-you-go 'Service Solutions' capped price program.

And if you're happy to fork over a little more up-front, there's a four-year service deal at $6300, and five years coming in at $7050.
