Porsche Taycan vs Audi RS5

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.

Good looking, good to drive, and good to simply sit in, the Audi RS5 range ticks plenty of premium boxes. Whether you can live with the practicality pitfalls of the Coupe is up to you, but if you can't, might I suggest taking a wander over to our RS4 Avant review?

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.

I defy anyone to describe the RS5, and especially the Coupe, as anything but stunning. Seriously, the near perfect proportions and swept-back styling make it look fast even when it's parked. 

Up front, there's a new-look black-mesh grille that's been given a 3D effect, like it juts out over the road in front it, while the thing headlights have been carved back into the body work like they're been windswept under hard acceleration.

The 20-inch darkened alloys fill the arches, too, with a sharp body crease that runs from the front headlight all the way back to the bulging shoulder lines above the rear tyres accentuating the curves.

Inside, the RS5 is a sea of black Nappa leather and sporty touches, and we particularly like the chunky, flat-bottomed steering wheel, which both looks - and feels - great.

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.

We only tested the Coupe, and I can tell you that the practicality perks on offer largely depend on where you're sitting.

Up front, you're spoiled for room in the two-door Coupe, with the two spacious seats separated by a sizeable centre console that's also home to two cupholders and a variety of cubbies, with extra bottle storage in each of the front doors. 

The back seat, though, is a little, or a lot, tighter, with come acrobatics required to even climb into it, given the Coupe only has two doors. The Sportback offers two more doors, which will surely make the process a little easier. 

The Coupe measures 4723mm in length, 1866mm in width and 1372mm in height, and will deliver a decent 410 litres in luggage space in the boot. The Sportback measures in at 4783mm, 1866mm and 1399mm, and boosts your luggage space to 465 litres.

Either vehicle has your tech needs sorted, with an abundance of USB and power outlets serving both front and backseat riders.

It's available as a Coupe or a Sportback, but either way, the RS5 commands a $150,900 asking price. And that's not chump change, but Audi's performance model does come with a lot of bang for those bucks.

We'll get to the engine and safety stuff in a moment, but in terms of fruit, you'll find 20-inch alloys outside, as well sportier RS body styling, sport brakes, Matrix LED headlights, keyless entry and push-button start and heated mirrors, a sunroof and privacy glass. Inside, there's Nappa leather seats (heated in the front), illuminated door sills, stainless steel pedals and ambient interior lighting.

The tech stuff is handled by a new 10.1-inch central touchscreen that gets both Apple CarPlay and Android Auto, as well as Audi's Virtual Cockpit, which replaces the dials in the driver's binnacle with a digital screen. There's also wireless phone charging, and a killer 19-speaker Bang and Olufsen sound system.

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.

Its a terrific engine, this - a twin-turbo 2.9-litre six-cylinder TFSI that will deliver 331kW at 5700rpm and 600Nm at 1900rpm, sending it thundering to all four wheels (because quattro) via an eight-speed tiptronic automatic.

That's enough, says Audi, to deliver a 0-100km/h sprint time of 3.9 seconds in the Coupe and the Sportback. Which is very, very quick.

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.

The RS5 Coupe will sip a claimed 9.4L/100km on the combined cycle, and emit a claimed 208g/km of Co2. It's fitted with a 58-litre fuel tank. 

The RS5 Coupe will the same 9.4L/100km, but emit 209g/km of Co2.

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.

With our time behind the wheel limited to the RS5 Coupe, we can only really report on how the two-door feels on the road, but given the prodigious power on offer, it's unlikely the addition of two doors is going to make the Sportback any slower. 

In short, the RS5 is thunderously fast, collecting speed with utter nonchalance thanks to this thick and endless-feeling supply of power unleashed whenever you plant your right foot.

It makes even the most ham-fisted attempts at cornering feel fast as lightning, with the power flow able to make up for every slow entry and exit by simply piling on pace between bends. 

But that's what you expect from an RS model, right? So perhaps more impressive is the RS5's ability to transform back into a relatively sedate urban cruiser when the red mist subsides. The suspension is firm, especially over rough road surfaces, and you do need to be a little careful with the accelerator to avoid that lurching feeling at every green light, but driven calmly, it doubles as a everyday car quite nicely.

Like in the RS4, we did find the gearbox felt a little quick to change at pace, shifting up or down at strange moments on the way into or out of corners, but you can reclaim control via the paddle shifters.

The safety story begins with six (Coupe) or eight (Sportback), and the usual suite of braking and traction aids, but then climbs into the tech-savvy stuff from there.

You get a 360-degree camera, adaptive cruise with stop and go, active lane assist, front and rear parking sensors, AEB with pedestrian detection, rear cross-traffic alert, an exit warning system, blind-spot monitoring and turn assist, which monitors oncoming traffic when making a turn.

It's a lot of gear, and it all contributes to Audi's five-star ANCAP safety rating, awarded in 2017 to the A5 range.

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).

Audi vehicles are covered by a three-year, unlimited-kilometre warranty, which is feeling more than a little underdone when compared to some competitors.

Services are due every 12 months or 15,000kms, and Audi allows you to pre-pay your service costs for the first five years, at a cost of $3,050.
