What are the running costs?

During our time with the Avenger, it averaged a respectable 4.15 miles per kWh on a mixture of A-road and town driving. That figure will tumble during extended periods of motorway driving, but a real-world range of 200 miles should still be achievable.

That’s better than older e-CMP2 cars such as the pre-facelifted Peugeot e-2008 or the Vauxhall Mokka Electric. That’s because the latest version of the platform has a larger 54kWh liquid-cooled battery pack, a more efficient electric motor and a standard heat pump.

Charge times are pretty good for the class, too. The Avenger comes as standard with 100kW DC rapid charging as standard, which can charge the battery from 20-80% capacity in just 24 minutes. Using a slower 7.4kW AC home wallbox, a full charge takes around eight hours. For the sake of comparison, it takes the Kia Niro EV nine and a half hours to fully recharge at a 7.4kW AC wallbox (because it has a larger 64.8kWh battery pack).

Servicing and warranty

Electric cars might have a lot fewer mechanical components than a combustion-engined car, but they still need to be regularly serviced. Jeep recommends you service the Avenger every year or 8,000 miles, whatever comes first.

That’s quite a short service interval. For context, the Hyundai Kona Electric only needs to be serviced every two years or 15,000 miles. To balance this out, every new Jeep is sold with a complimentary three-year service package and one year’s worth of roadside assistance.

The Avenger comes with a three-year/60,000-mile vehicle warranty as standard, although you can choose to extend this for an additional fee. Like most electric cars, the EV’s battery pack has a separate warranty for eight years or 100,000 miles – and Jeep says it’ll recycle the batteries at the end of the car’s life, too.

Despite these benefits, the Avenger’s warranty looks rather stingy compared to the seven-year packages offered with the Kia Niro EV and MG ZS EV.

Reliability

• Platform has been around for a while
• Motor and battery used in 600e/Corsa
• Less to break than in a petrol car

The Avenger is based on Stellantis’s e-CMP architecture, which has been around since 2019. The platform is used to prop up almost every small electric car from the group, including the Peugeot e-2008 and Vauxhall Corsa Electric – and the components have proved themselves to be reliable thus far.

However, Stellantis updated the platform in 2023, adding a new motor and a larger battery pack. The Avenger is one of the first cars on the road to feature the fresh tech, so we’ll have to wait and see how it performs over time. If that scares you, take comfort in the knowledge that electric cars are generally more reliable than petrol cars simply because there are fewer moving parts in their powertrains to break.
