Porsche Taycan vs Genesis G80

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.

Overall, then, the flagship G80 tries to be docile Clark Kent and the amazing Superman in one. As such, it stretches itself trying to be both a luxury GT and high-functioning sports sedan.

But while it doesn’t quite achieve either perfectly the Genesis gets near enough for most – especially at its exceptional price point.

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.

Australia never saw the original 'BH'-series Genesis, which was created primarily with US buyers in mind to be a 5 Series alternative at a 3 Series price, complete with rear-wheel drive and advanced chassis dynamics.

Hyundai spun the series off as a stand-alone brand in the mid-2010s within the second-gen 'DH' Genesis’ run (that did include Australia) from 2015, which is when the G80 badge arrived, while the 'RG3' redesign you see here launched in 2020.

What you’re seeing here, then, is a facelift of a half-decade-old design, and doesn’t it give off Bentley vibes? From that blocky nose with its latticed grille to the sleek profile, the five-metre long by two-metre wide G80 passes for a Continental GT wannabe. Particularly in SL guise. And a convincing one at that.

When it comes to the interior, look around. A 27-inch OLED touchscreen takes in the crisp digital instrumentation and slick multimedia displays.

We like the configurable widgets that come complete with pictures for instant recognition, and the fact that Genesis decided to put an equally-user-friendly climate-control screen below, so eyes never need to leave the road once you quickly learn where all the switchgear is.

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.

Size may not be everything, some say, but it sure says a lot when a medium-sized luxury sedan is long enough to swing it with some large Germans. And in this case, the impressive dimensions are enhanced by a three-metre-plus wheelbase.

Behind the soft-close doors, you’re met with a cabin defined by the luxury of space and isolation from the outside world – just what you’d expect from a full-sized flagship sedan. There’s room to stretch in all five seats.

Plus, in the SL, the seats and chunky steering wheel silently whirr out of the way for easier entry and egress, before sliding back to their previous-memory positions.

The front seats are among the best we’ve experienced in a long time, holding and caressing in all the right places. Switching drive modes increases bolstering and/or support, whilst longer thighs will appreciate the extendable ottoman feature. Hot/cold control and a prodding massage function further enhances the users’ pleasure.

As in all Hyundai products the digital instrumentation and media touchscreen are paragons of simplicity and clarity.

Actual knobs for audio, tuning, fan and temperature controls flank these, along with buttons for 'Home', 'Menu', 'Driving Modes', 'Cameras' and parking sensors.

So thoughtful, so easy. Even vision isn’t too bad, aided of course by the surround-views available. This is quite an unintimidating vehicle to judge when parking despite its length.

Issues? The gear selector is the circular variety Jaguar debuted with the original XF during the late 2000s and is a bit clumsy to use; sited in prime console real estate, the cupholder lid is set-up for left-hand drive, meaning it provides a (minor) obstacle for the driver when open; the test car’s carbon-fibre-look trim won’t be to everybody’s taste and there’s no walk-to/away automatic central locking.

Meanwhile, the rear seat is in the spirit of a true limo.

Wide doors allow for easy entry/egress, revealing impressive levels of space for shoulders, hips, knees and feet (though headroom might be a mite tight for taller dos due to the sunroof). The left-side rear occupant can re-position the seat in front automatically to boost legroom even more.

Airliner premium-economy class-style backrest reclination is included. And you can sink yourself or your loose digits into the tactile and aromatic bliss of the perforated Nappa leather, thick pile carpet, suede trimmed pillars and ceiling and quality textures, further upping the luxury ante.

The large folding armrest facilitates access to heating/ventilation, audio, a sunblind, cupholders, phone chargers, USB-C ports and hidden storage.

The fortunate rear-seat passengers also face air vents and a separate climate control panel from the front-seat riders. So decadent. This was clearly designed for chauffer opulence and it shows. Very difficult to fault.

But further back, it isn’t so bountiful. Literally.

The pleasingly plush boot measures in at a smallish 424 litres, and that’s almost 100L down on a 520i’s. And while it comes with a ski or 'Bunnings port', simple folding backrests would have been more practical, particularly for car reviewers who occasionally need to transport their bicycle.

Oh well, that’s what SUVs are for.

The space-saver spare, in lieu of the hated tyre repair kit, is welcome, though. Thank you.

That HSV Grange analogy is pretty close to what the G80 3.5T AWD SL from $121,200 (all prices are before on-road costs) represents, and not just in dimensions and performance.

Adjusted for inflation, a 2015 Grange from $86,990 would equate to about $115,300 today, which nestles in neatly between the ‘base’ G80 2.5T rear-driver from $104,200 and 3.5T AWD SL.

And, like the big Holdens and Fords of yesteryear, the Genesis annihilates the German luxury sedan triumvirate for value for money as well as bang for your buck, when you consider what the competition is at its price point: Audi A6 45 TFSI quattro S Line from $122,415, BMW 520i from $114,900 and Mercedes-Benz E200 from $117,900.

Nowadays, even the entry-level Euro grades are pretty well specified, but all have 2.0-litre, four-cylinder, turbo-petrol engines of between 150kW and 180kW outputs and two-wheel drive, against the Genesis’ 279kW 3.5-litre V6 twin-turbo and AWD.

And then there’s the SL equipment levels, that includes everything you’d expect from a machine that is built like a Lexus, behaves like a BMW and wants to be as bourgeois as an S-Class Benz, with powered, electric and wireless everything.

It’s easier to list what’s missing: namely, walk-away door locking.

Still, listing some of the standout features is editorially required, so the SL’s lucky occupants can indulge in a heated front console armrest complete with UV-C sanitisation, a real-time concierge service with a five-year subscription included, a fingerprint recognition system for extra security (freeing society from a key!), a powered rear-window shade and the quietness that active noise-cancellation brings. And all are new with the MY25 facelift.

More opulence comes in the form of Nappa quilted leather upholstery, surround-view monitors, 18-way powered/heated/vented/memory front seats with massaging and ottoman extenders, powered reclining/vented/heated rear outboard seats with (manual) sun-blinds, tri-zone climate functionality with rear-seat controls, front and rear wireless smartphone chargers, 18-speaker Bang & Olufsen audio (with epic sound), soft-close doors, suede headlining, a panoramic sunroof with powered blind, solar-controlled glass, a powered boot lid with valet mode and remote-control parking.

We are pretty sure you won’t find this combination of gear in your entry-level German sedans at the 3.5T’s price point.

Genesis has also crammed in as much active and passive safety as possible. More on that in detail later on.

Note that there is also an all-electric G80 Signature Electrified AWD version from $155,000, making it the series’ true flagship.

Successive federal governments in Australia with their Luxury Car Tax have made this sort of vehicle a questionable value proposition as it balloons their prices, but within the context of what else is available, the G80 makes for a brave and bold alternative to formidable yet predictable alternatives.

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.

As the alphanumerics suggest, the G80 3.5T AWD is powered by a 3.5-litre twin-turbo V6 petrol engine, producing a hefty 279kW of power at 5800rpm and 530Nm of torque between 1300-4500rpm.

Tipping the scales at 2095kg (kerb), the SL’s power-to-weight ratio is 133kW/tonne.

Drive is sent to all four wheels via an eight-speed torque-converter automatic transmission. 'Normal', 'Sport' and 'Eco' modes are fitted.

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.

Here is where the G80 has all four wheels rooted more in the past than in the future.

With no electrification of any variety (hybrid, in other words), high fuel consumption is always going to be the real price paid by going for a Euro-5 spec twin-turbo V6 weighing some 2100kg.

The official combined average figure is 11 litres per 100km, for a corresponding carbon-dioxide emissions rating of 250 grams/km. On the highway that drops to 7.9L/100km and soars to 16.3L/100km in the city cycle.

With a 73L fuel tank, that combined average number means a driver can expect around 660km of range between refills of 95 RON premium petrol, though Genesis says this G80 will also run on E10 ethanol blend.

Now, our trip computer said that we averaged less than the official figure, at just 9.7L/100km, but our pump-to-pump testing ended up being 11.4L/100km. Which isn’t that bad.

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.

The Genesis G80 3.5T AWD SL drives in a similar way to the big brutish American-inspired Caprice and HSV Grange V8s, in that it delivers effortless, lazy performance with a sophisticated twist.

No slouch off the line even in Eco mode, the twin-turbo V6 leaps into action if you’re heavy on the throttle in Comfort mode, hunkering down as the speed piles on quickly.

With 'Launch Control', the claimed 0-100km/h sprint time is 4.9 seconds, though in regular mode it is rated at 5.1s on the way to a top speed of 250km/h.

And while the enhanced exhaust orchestrates a nice warble from behind, it remains a strong, smooth and silent performer.

The AWD system is RWD-biased and is continuously variable according to prevailing conditions, performance and grip.

The SL also features an electronic limited-slip differential for better traction and grip, as well as rear-wheel steering that either counter-steers the rear wheels in relation to the front ones for a tighter turning circle (11.8m) or parallel steers them for “enhanced steering responsiveness and stability at high speed.”

Selecting 'Sport' or 'Sport+' is met with distinctly more-urgent responses, with the transmission holding on to ratios as the revs approach the red line, which can be annoying around town.

It’s quite surprising – and probably a good thing – that the beautifully balanced and connected steering can be light and easy when you’re relaxed, and yet hefty to the point of feeling heavy when you’re really on it. Likewise, the brakes in 'Comfort' are pleasantly progressive. In 'Brake Sport' they’re fiercely responsive.

Note that, in Sport+ with the safeties off, the SL's tail can become very playful indeed, even in bone-dry conditions.

Suspension is via multi-links at both ends of the car, whilst the SL grade includes what Genesis calls “Road Preview Electronic Control Suspension (ECS)”, that scans the road ahead and then adjusts the adaptive dampers for better ride comfort.

That all said, the Genesis’ sheer size and weight keep it from feeling like an out-and-out sports sedan. The speed and AWD grip is there - tyres are Michelin Pilot Sport 4S (245/40 fr - 275/35 rr) - and the handling results in some pretty astounding agility for one so large, but the steering connection, balance and alacrity are more about confidence and competence than light-footed athleticism.

This is no cut-price BMW M5. But HSV Grange owners might recognise something in its muscular good manners.

And what of the SL’s four-wheel steering? It provides a degree of tuck-in at speed which can catch out the unaware driver, though of course, it is also a boon for round-town manoeuvrability. The tight turning circle that ensues is incredible for one so long.

Ultimately, though, it is a large and heavy sedan that never quite stops feeling that way. It won’t shrink around you despite being an easy and rewarding car to drive.

Out in the wet, the AWD contributes to the G80’s squatted-down attitude, feeling impervious to prevailing external conditions.

But it’s also not quite the sumptuous luxury liner that, say, a Mercedes S450 is.

Very civilised on smooth roads, with a decent level of absorption from the multi-link suspension, the G80 struggles a little with smaller-frequency bumps at times, but then does a great job smothering the larger ones. It is certainly within the luxury sedan expectations for refinement, isolation and ride comfort, but just not the best.

If you stick with freeways and highways, this thing will bring years of civilised pleasure and punchy performance. It is a rapid yet relaxed grand touring family cruiser.

The Genesis G80 scored a maximum five-star ANCAP assessment all the way back in December 2020, though this figure does not cover the 3.5T model as tested by us.

Along with 10 airbags (including front-centre and driver’s knee protection), it is fitted with a wide variety of advanced driver assist systems (ADAS).

These include 'Autonomous Emergency Braking' (AEB) with forward-collision avoidance (taking in car/pedestrian/cyclist as well as junction turning/crossing detection), lane-keep assist, lane-change and evasive steering assist, rear cross-traffic alert, blind-spot warning/collision avoidance, traffic-sign recognition, adaptive cruise control, parking collision avoidance, safe-exit alert, surround-view monitors, driver-attention warning, traffic-sign recognition and auto high beams.

There are also two ISOFIX child-seat fixtures and a trio of child-seat anchorage points in the back seat.

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).

The Genesis G80 comes with a five-year/unlimited kilometre warranty, five years of what it calls 'premium' roadside assistance (increased to 10 years if serviced at a Genesis dealer) and five years/75,000km of free servicing. Service intervals are every 12 months or 15,000km.

While these are about on-par with most brands, it is behind better mainstream warranty and aftersales services, which are seven, and in a few cases, 10 years in length.
