Porsche Cayenne vs Renault ZOE

What's the difference?

Of all the super SUVs I've piloted, the Porsche Cayenne Turbo GT is the best all-rounder in terms of performance, comfort, cabin technology and style.

As a family car it's roomy, practical and easy to use and drive daily.

As a performance car the Turbo GT is stupidly quick, with the agility of a sports car. Sure, a 911 would leave it behind on a twisty race track, but this SUV is close to having that sportscar experience and keeping your family, as well.

The Renault Zoe is a fun to drive, ultra-efficient, practical little hatch. But the dollar-shaped elephant in the room is its price. Without the government ZEV subsidies offered in other markets, it's wickedly expensive, and with fresh competition in the shape of a new 'normalised' Nissan Leaf coming soon it'll have to work hard to wean more than a handful of small-car buyers off their fossil-fuel addiction.

This might be a personal thing but to me nearly all Porsches look better from the back than the front.

It's the wide stance and powerful haunches, the hunkered down suction-capped-to-the-road look that does it for me and the Cayenne Turbo GT, despite being an SUV, passes this important Porsche checklist item.

The GT aero kit only serves to make this SUV look more of a beast, and the gold-bronze looking satin Neodyne wheels are a Porsche theme that I've not always been a fan of, but I get the historic connection.

If only the Turbo GT could look a little less like other Cayennes from the front. This is the king of the SUV range and despite the apron and bumper already being exclusive to this model, there should be more.

Vents in the wheel arches, carbon bonnet with nostrils GT3-style perhaps? Or is that going too far? If you do want something more lairy then there's always the Urus.

The Cayenne Turbo GT's cabin is stunning in its plushness and modern surprises such as the passenger display, the hoodless instrument digital cluster, the lashings of Race-Tex upholstery everywhere. It's perfectly Porsche. High-performance meets high-end.

It's also highly practical. Let's talk about that.

Renault claims no less than 60 patents came out of the Zoe's development, but while BMW's i3 is as hip as Kendrick Lamar on his third encore, and even Toyota's long-serving Prius hybrid still looks ready to roll onto the set of the next Avengers movie, this little hatch isn't shouty at all.

It seamlessly merges into the automotive landscape. A cute, small car with a few flashy blue bits in its head and tail-lights giving the only clue to its distinctly unusual internals.

Underpinned by the same platform as the Clio (with an identical wheelbase) the Zoe is slightly longer (+21mm), fractionally thinner (-2mm) and quite a bit taller (+114mm) than its conventionally powered sibling.

Lead exterior designer  Jean Sémériva has literally left his mark on the car, with a full-size thumb print applied in low-relief to the rear door handles. Nice touch.

And monsieur Sémériva has shown admirable restraint in a cool design combining soft curves around the nose, front guards and rear end, with sharp character lines top and tailing the car's flanks.

Vaguely diamond-shaped tail-lights mix a clear lens cover with those nifty blue highlights and brilliant LEDs for an arresting brake and indicator display.

Open the door and a similar blend of tech and tradition creates a clean and simple interior, with strategically placed bright-metal finishes highlighting key elements.

A broad TFT digital instrument screen sits under a minimalist hood, with the 7.0-inch 'R-Link' multimedia screen dominating a central stack lifted by a shiny black face and an illuminated blue keyline around the heating and ventilation controls.

A printed circuit pictogram on the front headrests and left-hand side of the dash is a creative reminder of the Zoe's means of propulsion. And the front seats feature a decorative curved panel, defined by dark piping on each side of the backrest.

Tech highlights include the TomTom Live nav system's ability to describe a circle showing the car's operational radius on current charge, determining whether you can reach a nominated destination. It also taps you into weather updates, traffic danger zones and Renault Assistance.

Plus, the drive-management system can report on energy usage and assess driving behaviour, so lead foots have nowhere to hide.

The Porsche Cayenne Turbo GT only makes one compromise on practicality and that's the removal of the middle seat in the back, which, with just two kids isn't used all the time but on average we might need it once a week for school mates and cousins.

Instead of a middle seat there is a shallow tray, which will fit a phone or in our case leaves and rocks found at the park.

So, yes, the Turbo GT is a four-seater only, but this is a spacious, large SUV with good head and legroom, wide-opening doors for easy entry and exit, and air suspension which can raise and lower the height for easy access.

Storage is excellent with enormous door pockets in the front and back and there are four cupholders.

There's a wireless phone charger in the front and two USB-C ports as well, plus two USB-C sockets in the back.

Four-zone climate control means the kids in the back can set their own temperatures. They also have heated seats.

I was disappointed to see there aren't sunshades for the rear windows - pretty vital in Australia where it feels like we're only about 50 metres away from the sun.

The Turbo GT's 576-litre boot just managed to fit our pram and a week's shopping, which is our minimum standard for living. Any more space is a bonus.

Like most compact hatches the Zoe offers plenty of space up front and gets a bit squeezy in the back. Although the first surprise is that there's no height adjustment for either front seat.

Happily that wasn't a big issue. At 183cm I was still able to find a good driving position, with storage running to two cupholders (one small, one laughably tiny), plus a pen slot and two oddments trays in the centre console. The second of those trays houses a 12-volt outlet, SD card slot, 'aux-in' jack and USB port.

There are small bottleholders and storage pockets in each front door, a medium-size (7.0-litre) glove box with an open tray above it, and a small tray on the lower part of the dash on the driver's side.

Rear head and legroom is passable for a car of this size, but storage is limited to modest door bins and a single cupholder at the back of the centre console.

However, it's cargo space where the Zoe really raises eyebrows, with 338 litres available (to the parcel shelf) with the single piece rear seatback (as in, it doesn't split-fold) upright.

That's enough to easily swallow our three-piece hard suitcase set (35, 68 and 105 litres), or the CarsGuide pram. In fact, we were able to fit the largest suitcase and the pram at the same time, which is mighty impressive for a city-sized hatch. Push the rear seat flat and space grows to 1225 litres (to the roof), which is heaps.

Carpeting for the boot has been sourced from the cheap 'n' cheerful bin, but there are D-shaped anchor shackles, decent lighting and handy bag hooks back there.

The boot's unlikely volume is partly due to the absence of a spare of any description, a repair/inflator kit being your only option. And in case you were wondering, towing is "prohibited" (Renault's word, not mine).

Built at Renault's Flins plant, 40km west of Paris, on the same line as the Clio, the Zoe's offered in two grades; Life ($47,490, before on-road costs), and Intens ($49,490 BOC) as tested here.

That's big bucks for a little car. At just under $50,000 you're looking at internal-combustion competitors like the Audi A3, BMW 1 Series, and Merc A-Class. And while the Zoe's a long way from spartan, it's an equal distance away from luxurious.

That said, the standard features list includes, climate control (with remote 'pre conditioning' activation), 16-inch 'Black Shadow' alloy rims, cruise control, 3D Arkamys audio (with DAB radio, voice recognition, two 'boomer' speakers, two rear bi-cone speakers, and two tweeters), 'Renault Smartkey' keyless entry and start, auto headlights, and rain-sensing wipers.

Plus, you also get rear parking sensors, a reversing camera, the 7.0-inch 'R-Link' multimedia system (with 'Text to Speech' function), one-touch driver's window (the base Life grade misses this), a leather-trimmed steering wheel and gear knob plus black and grey cloth trim (with snazzy contrast stitching).

The DRLs may be LED but the headlights are halogen (a sure sign of this car's age), Apple CarPlay and Android Auto are MIA, and metallic paint, as per 'our' car's 'Zircon Blue' finish is $550 extra. 'Glacier White' is the only no-cost option from six available shades.

As a middle-aged parent with two children, a Porsche that I don't have to crawl into and out of like a cubby house is a great thing.

What's even better is that this ‘easy access' Porsche is every bit as brutally powerful and fast as the quintessentially ‘pure' Porsche, the 911. Actually, it's more powerful and faster.

The Turbo GT's twin-turbo 4.0-litre V8 petrol engine makes 485kW and 850Nm with drive going through an eight-speed transmission to all four wheels.

In comparison, a Porsche 911 GT3 RS, arguably the most brutal and anti-social 911, has 386kW/485Nm.

I haven't made a mistake. Those are the real numbers. And it's only when you step on the accelerator in the Cayenne Turbo GT, and it feels like somebody's sat down on your chest, that you realise what a big deal this is.

That is such a colossal amount of oomph that this 2.2-tonne family SUV can accelerate from 0-100km/h in 3.3 seconds.

The 911 GT3 RS can do it in 3.2 and it has a roll cage and a fixed rear wing the size of a bedroom door.

And yes, we're now coming into a digital age where Teslas and other electric SUVs are quick, too, but can they go around corners like a Porsche Cayenne Turbo GT?

Do they have the same rumble and roar as a twin-turbo V8 that's terrifying and enticing at the same time.

The correct answer is, absolutely not.

The Zoe is powered by Renault's R90 synchronous electric motor, producing 68kW from 3000-5000rpm and 225Nm from step-off. Drive goes to the front wheels through a single reduction gear auto transmission.

Claimed acceleration for the city-specific 0-50km/h run is a handy 4.0sec, with the more grown-up 0-100km/h sprint taking a leisurely 13.2sec. Flat biscuit is 135km/h.

Seriously? This is a 2.0-tonne twin-turbo petrol V8 with a 90-litre fuel tank. Even the Porsche specs sheet doesn't understand the question because in the column for fuel efficiency there are three letters - tbc.

My own testing saw me record 22.5 L/100km at the fuel pump, which means I enjoyed driving the car very much.

A little digging around reveals Porsche globally claims the Turbo GT will use 12.6L/100km, over a combination of open and urban roads.

You might not have as much fun as I did but easing back a little might get you closer to the 700km of range this more frugal consumption figure appears to offer.

While efficient it isn't, I'm not going to mark the Turbo GT too much here because compared to its petrol rivals the fuel consumption is what I'd expect from such a high-output heavy SUV.

None. Next question...

You can have the argument about fuel consumed and source emissions produced in generating the energy required to charge the Zoe's battery, but the fact is this car doesn't consume any fossil fuel and produces zero tailpipe emissions. Helped by the fact it doesn't have a tailpipe.

When launched in 2016, the Zoe's upgraded 41kWh 'Z.E. 40' high-energy lithium-ion battery ranked as the highest energy density automotive unit available.

Developed in collaboration with LG Chem in South Korea, it houses 12 modules (of 16 cells each) for a total of 912 individual cells and weighs in at 305kg.

Renault lists a driving range of 403km for the New European Driving Cycle (NEDC), with a real-world number of 300km a more realistic estimate. And that's almost exactly the range we achieved over a mix of city, suburban and freeway running in seven days with the car. Using overnight electricity rates, a full charge should average less than $8.00.

The Zoe's on-board 'Chameleon' charger allows it to be charged using different power levels (single or three-phase) through the same socket, from 3kW up to 22kW. A Type 2 charging cable (6.5m) for wall box and public charging points (in a natty canvas Z.E. bag) is included with the car.

According to Renault, a wall-box charger (not included with the car) is typically $1600 to $2000 for a residential installation and a mid-range 11kW unit will allow you to charge up in around four hours. High-powered 'Fast' and even juicier 'Rapid' charging points would reduce that time appreciably.

The dash indicator displays charge level and remaining range calculated over the last 200km of driving. A reset function can drop that to an average of the last 30km.

We'll touch on it further in the Driving section but regenerative braking, low-rolling resistance tyres, and 'Eco' mode (reducing air-con load and motor output) are big contributors to maximum range.

And while cabin cooling comes courtesy of a conventional a/c unit, heating is far more exotic. The Zoe's 'Heat Pump' system traps calories in the ambient air outside the car, with a pump compressing and heating them, then directing the heated air into the car, with no impact on range. Super clever.

Never have I met a car this powerful and superbly athletic that is as pleasurable to drive alone on great, fast roads as it is to pilot at 50km/h in the suburbs with a family on board.

It exceeds my understanding of engineering that something this large can move so quickly. That in an instant can turn and tip into a corner with such precision and effortlessness.

Yet it can switch seamlessly and happily to coping with speed bumps and potholes, delivering a ride so comfortable it'll send babies off to sleep. And it did.

The only issue, and this is such a tiny thing, is the dash-mounted gearshift, which means having to reach up and select Drive or Reverse or Park, which, when executing a three-point turn, is necessarily frustrating.

Still, I'm giving the Turbo GT a 10 out of 10 for driving under all conditions, and we didn't even go off-road, which of course you can do, as long as it's not too wild.

Some believe cars have a soul, but the Renault Zoe expresses its feelings with a distinctive accent, the car's 'Z.E. Voice' function giving an audible warning to pedestrians up to 30km/h (when wind and tyre noise take over).

The whirring hum sounds like The Beach Boys warming up the theremin for a rendition of 'Good Vibrations'. Spooky and fun in equal measure.

Like all electric cars the Renault Zoe accelerates quickly from rest, thanks to the motor's ability to deliver maximum torque (225kW) from step off.

At 1480kg (battery 305kg) the Zoe is 177kg lighter than an equivalent Clio, so it's snappy in its natural city habitat, but thrust begins to taper off markedly around the 55-60km/h mark.

The single-speed, reduction gear automatic transmission combines with the motor's sewing-machine smoothness to provide close to perfect drive delivery.

Sitting on the same 'B platform' as the Clio (and 20 other Renault–Nissan–Mitsubishi Alliance models) the Zoe features a strut front, beam rear suspension set-up.

Ride comfort is surprisingly good for such a small hatch, and the battery's location under the floor sets up a centre of gravity 35mm lower than the Clio's, so despite a 59 per cent front/41 per cent rear weight distribution, the car feels well planted in corners.

...the dash graphic – a blue AA-style battery surrounded by rising rings of energy – is reminiscent of 'the machine man' animating in Fritz Lang's Metropolis.

The standard 16-inch alloy wheels are shod with Michelin Energy E-V low-rolling-resistance tyres (195/55), which won't win you pole on a qualifying lap, but are commendably quiet.

There are three driving modes, with the dash graphics aligning to each – Eco (green), Neutral (blue), and Dynamic (violet).

But ECO mode should be reserved for hardcore environmental warriors only. Press the console-mounted button and power from the motor is reduced and air-con output is limited.

It may increase range by a claimed 10 per cent, but what price your sanity? This setting sucks out the car's will to live, and thankfully a second press of the button or pinning the throttle pedal to the floor sees full-strength service resumed. Phew.

The regenerative deceleration and braking system distributes braking force between the clamping of the brake pads and the engine on over-run to maximise battery charge.

While the BMW i3's regen system will have you head-butting the steering wheel (not really) when you get off the throttle, the Zoe's system is more subtle, and watching the dash graphic – a blue AA-style battery surrounded by rising rings of energy – is reminiscent of 'the machine man' animating in Fritz Lang's Metropolis.

Speaking of brakes, the fronts are relatively delicate 258mm vented discs and the 9.0-inch rear drums look like miniature versions of the elaborately fluted units found on 1920s Grand Prix racers. They're beautiful and work well.

Some niggles. The wipers skip and stutter in light rain, the lightweight doors feel clangy when you close them, and the R-Link multimedia system is annoyingly flaky when recognising content (or not) via Bluetooth or USB from a mobile device.

The Zoe hasn't been assessed by ANCAP but was awarded a maximum five-star ranking by EuroNCAP in 2013, with annual reviews allowing it to maintain that score through to April this year.

Active crash prevention tech includes ABS, EBD, EBA, ESC, traction control, tyre-pressure-loss sensors, rear parking sensors and a reversing camera.

But forget about more recent systems like AEB, lane-keeping assistance, blind-spot monitoring, cross-traffic alerts or adaptive cruise.

Interestingly, the Zoe continuously monitors the state of each cell in the battery pack and will switch off current immediately if it senses an overheating-style abnormality.

If an impact is unavoidable the airbag count runs to six - driver and passenger front, front side (head and thorax), and full-length side curtain.

There are three top tethers and two ISOFIX positions for child seats/baby capsules across the back row, and all seats feature Renault's 'Fix4Sure' anti-submarining design.

The Cayenne Turbo GT is covered by Porsche's three-year, unlimited kilometre warranty, which is lagging behind in terms of duration even compared to other luxury brands such as Mercedes-Benz, which offers five years.

Servicing is recommended annually or every 15,000km, although there isn't a capped price maintenance plan with final costs determined at the dealer level (in line with variable labour rates by state or territory).

According to Renault, the R90 motor is "maintenance-free", waterproof and requires no lubrication, with servicing costs "20 per cent lower than an equivalent ICE (internal combustion engine) vehicle."

Despite that, servicing is recommended every 12 months/30,000km for an estimated cost of $231 each time.

Warranty is three years/unlimited km with 24-hour roadside assist included for the first year, and three after that if you have your car serviced at an authorised Renault dealer.

The battery is covered by a separate five year/100,000km warranty.
