On 7 August Auto Express presented a ‘Best Superminis’ shortlist: ‘The 10 best superminis you’ll be able to buy in the coming months’. Zoe came number nine in the list:
“No one has made a commitment to electric cars quite like Renault, and the Clio-sized Zoe is expected to be the big-seller, with tens of thousands finding homes every year. What sets the Zoe apart is its pricing structure: unlike the Nissan Leaf buyers pay from £13,650 for the car then rent the batteries for around £70 a month, making it a far more attractive proposition. Power comes from an 88bhp electric motor – 20bhp less than the Leaf – which is mounted on the front axle, while the battery pack is stuffed under the floor. Charging takes anywhere between 30 minutes from a industrial-spec fast charger to nine hours from a household socket. This provides 130 miles of driving before it’s time to top up again.”
Cold Weather Testing
On 17 August Renault released the third instalment of its Renault ZOE Confidential blog, this one about cold weather tests in Lapland. Judging by the vehicle’s registration number (HCU889), it was the same one that took part in the similar testsdescribed by Auto Express in March.
It sounds like the tests were comprehensive, covering driving and handling plus vehicle components including the battery and the charging system. Renault reported that the Zoe achieved top marks, especially compared to internal-combustion cars:
- “motor start-up: exactly the same at -30°C as in temperate weather, i.e. immediately and silently. No engine warm-up, no smoke plumes, no clatter.
- “first runs: the motor is not affected by the cold. Motorists can drive off straight away and floor the accelerator without having to warm the car up. Also, while in motion, the battery heats up and gradually improves the points mentioned above.
- “heating: on top of being frugal, the heat pump provides heat fast. The car doesn’t need to be started several minutes beforehand.
- “pre-conditioning system: to heat the cabin up a little and defrost the windows before taking off, drivers simply pre-program the heating and the car is at “room temperature” when they get in. This will never be possible with a combustion vehicle, where the engine needs to be turned on.
- “Our engineers were pleasantly surprised by Renault ZOE – by the fast-action heat pump, by the strong performance of the battery on power in cold conditions and its ability to start the motor at very low temperatures, and by the car’s road holding, especially grip on slippery surfaces. The battery’s central and low position is a big advantage here.”
The use of a heat pump to provide heating in an EV is certainly an original and promising idea since its high efficiency should reduce energy consumption and so increase range, particularly in cold weather. There has been speculation that it could be transferred to the Nissan LEAF, the current best-selling EV from the Nissan-Renault alliance.
