Crucially the ZOE has been designed as an electric car from day one. This means that it doesn’t have the design compromises that come with adapting petrol and diesel models. The layout is reasonably conventional with the electric motor at the front under the bonnet, but the large battery is encased in the floor within the wheelbase.
Putting the battery in the floor gives the ZOE a low centre of gravity, keeps the batteries safe in an accident and means that you get a large 338-litre boot. There is a slight compromise for rear seat passengers as the rear seats are slightly raised reducing headroom, but there are three seatbelts and adults under six foot can squeeze in.
The big news however is the adoption of a new battery which demonstrates the rapid rate of development by packing 41 kWh into the same space as the previous 22 kWh battery whilst adding just 15 Kg in weight. Confusingly Renault has chosen to call models with the bigger pack ’40’ rather than 41. This takes the official range to 186 miles and the minimum real world winter range increases from 71 miles to 124 miles. This makes ZOE a viable everyday option for many.
There is a downside to this increase in usability which rather predictably is the price. Renault has opted to discontinue the 22 kWh battery which means that an entry-level ZOE is now a chunk more expensive, so if you didn’t need the extra range the decision is lamentable.
One of the big decisions facing prospective ZOE owners is charging options. Renault uses a different system to most, utilising AC charging for rapid as well as fast. This means it is limited to 43kW from rapid chargers, such as those at motorway services, which deliver 50kW+ to DC-enabled cars (ie. all other electric cars!).
Renault’s decision to lease the batteries has some insurance implications, but the battery will be replaced free of charge if it falls to less than 75% capacity at any time during the lease. It also makes the ZOE more affordable to buy. You can choose to buy the ZOE with batteries if you prefer, so it’s worth looking at both options to see which suits you best. Compared to a Clio, the ZOE is more expensive but has a bigger boot, has more gadgets, and according to Euro NCAP it’s safer too! If you travel less than 125 miles a day (or between charges) the ZOE actually makes more sense than the Clio. The electric car has come of age.
Estimated real world range: 124 miles winter / 186 miles summer (Renault estimates)
Official range 41kWh battery: 186 miles
Official electricity consumption: 178 Wh/km
Battery pack: 41 kWh lithium ion, warranty – replaced if less than 70% SOC retained within 5 year 60,000 miles when purchased outright, or 75% SOC for term of battery lease
Recharge time: 3kW 15 hours; 7kW (including home charger) 7 hours 25 mins; 22kW 2 hours 40 mins 0-80%; 43kW 1 hour 40 mins 0-80%.
Please note that CO2 emissions quoted for electric cars are not directly comparable to diesel and petrol cars. This is because CO2 emissions quoted are calculated by Green Car Guide and include the emissions created at the power station turning fuel (e.g. gas etc) into electricity and in transmitting and distributing the electricity to an end user. They do not include the actual production of the fuel (e.g. gas extraction and refinery emissions). Petrol and diesel emissions are supplied by car manufacturers and are based solely on the fuel burnt in the engine (tailpipe emissions) and do not include the production of the fuel or distribution to a fuel station. In practice this means that electric car emissions are over-estimated relative to petrol and diesel. For instance if an electric car, a petrol car, and a diesel car are all reported to emit 100 g/km CO2, the electric car actually has lower emissions.
