Holden Astra vs Renault ZOE

What's the difference?

The Astra's biggest problem is probably the Holden badge. Despite the company's best efforts, some buyers are wary of the company's longevity and some of the other cars in the range do the Astra no favours - Trax, Colorado and Barina feel cheap, because they are. The Astra isn't cheaply made and holds up very well in excellent company.

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.

The Astra is a sleek if slightly anonymous-looking thing. Having said that, it's a really nice design that looks more expensive than it is. That's important in this segment. Holden is at pains to tell us it's from Germany (the Astra is manufactured in Poland) and it does look Euro-influenced. Despite its coupe roofline, it's an easy in-and-out proposition but does sit a little lower than, say, an i30.

The odd blacked-out section of the C-pillar takes a bit of getting used to but the sheetmetal is otherwise faultless and well put together.

Inside it's a sea of grey plastic and various shades thereof, but again, it hangs together really well and is a welcome change from the Teutonically angular Golf. The materials are largely reasonable, but for some reason the stalks feel flimsy to touch and use.

The cloth trim is hardy but comfortable and I was grateful for its relative coolness versus what you might expect from the textile leather you're more likely to get at this level.

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.

Riding in the front, there's room aplenty for passengers, with good headroom and a well-designed space to maximise what's available. Rear seat passengers do okay as long as the front occupants are being generous, but the seat itself is comfortable and there's even good headroom, despite the falling roofline.

Only the front scores cupholders, with the rear passengers making do with door pockets that might swallow a small bottle. There isn't an armrest or air vents back there either.

There's somewhere for one front occupant to put their phone, a horizontal slot that doesn't like phones with covers or the larger format iPhones or Androids. If your phone does fit (iPhone Xs do, as it happens), it's useful because it's in your eyeline, although a bit untidy if you're plugged into the USB.

The boot starts at a class-compeititve 360 litres, rising to 1210 when you fold the seats down.

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.

The whole Astra range is turbo, but here in the cheaper seats it's a surprisingly capable 1.4-litre unit with 110kW and a healthy 240Nm. Power finds the road via the front wheels and a six-speed automatic. It's an otherwise unremarkable technical story, with start-stop to help cut fuel use.

The Astra is rated to tow 750kg unbraked and 1200kg braked.

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.

Holden claims the Astra will drink standard unleaded at the rate of 5.8L/100km on the combined cycle.

Our time with the car, which was a 70/30 mix of suburban and highway, yielded 8.3L/100km, and it's worth noting it was stinking hot for most of the time, so the air-con had to work hard.

The fuel tank is a little on the small side at 48 litres, between five and 10 litres smaller than some of its competitors, like i30 and Golf.

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.

I'm going to get my biggest gripe with the Astra out of the way first - the driving position is rendered awkward by the pedal placement. Every other part of the driving experience is perfectly fine, with good adjustment in the seat and steering wheel but the pedals are Not Right. The transition from accelerator to brake means a big lift of the right foot rather than a sideways shuffle and that gets boring. Perhaps I'm getting old and my knees are weak, but I ended up left-foot braking for a lot of the time.

On with the show. The Astra's 1.4 litre turbo is a punchy thing, more than vaguely reminiscent of Peugeot's excellent 1.2 in the 308. The six-speed auto isn't quite as well sorted, occasionally lurching a bit on light throttle like a dual-clutch. The pay-off for that is crisp shifts and a positive feel for most of the time.

The thing about the Astra is that it really takes it to its competition from behind the wheel. It feels almost as good as a Golf, i30 and arguably is as good as a Mazda3 thanks to its extra torque and better refinement.

It's very quiet, composed and is good fun if you like that sort of thing. Otherwise, it's streets ahead of the Corolla which continues to sell like it's going out of fashion.

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.

Holden's three year/100,000km warranty includes roadside assist for the duration. You can also extend the warranty by up to three years or to 175,000km, for an extra cost.

Servicing is scheduled every nine months or 15,000km. Holden calls its fixed-price servicing 'Know Your Price' and it applies for the first six services (63 months or 105,000km). The first four services are set at $249 each, and the final three $309.

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.
