Volvo EX40
The Mercedes-Benz CLA costs £6,005 more than the Volvo EX40. For that premium it adds 129 miles more WLTP range and 120 kW faster peak rapid charging. On EVcarsguide's combined category scores, the Mercedes-Benz CLA comes out ahead overall.
The Volvo EX40 is £6,005 cheaper to buy. The Mercedes-Benz CLA is cheaper to charge, roughly £120 a year versus £184 for the Volvo EX40, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Volvo EX40 comes out roughly £5,685 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
EVcarsguide estimates a real-world motorway range of about 403 miles for the Mercedes-Benz CLA and 242 miles for the Volvo EX40 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Mercedes-Benz CLA goes roughly 162 miles further between charging stops.
The two are within 18 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 545 mm of total clearance for the Mercedes-Benz CLA and about 527 mm of total clearance for the Volvo EX40.
