Mercedes-Benz CLA
Vauxhall Astra
The Mercedes-Benz CLA costs £15,620 more than the Vauxhall Astra. For that premium it adds 203 miles more WLTP range, 220 kW faster peak rapid charging and 53 litres more boot space. On EVcarsguide's combined category scores, the Mercedes-Benz CLA comes out ahead overall.
The Vauxhall Astra is £15,620 cheaper to buy. The Mercedes-Benz CLA is cheaper to charge, roughly £120 a year versus £168 for the Vauxhall Astra, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Vauxhall Astra comes out roughly £15,380 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 191 miles for the Vauxhall Astra - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Mercedes-Benz CLA goes roughly 212 miles further between charging stops.
The two are within 5 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 540 mm of total clearance for the Vauxhall Astra. The Vauxhall Astra also turns in a 0.7 m tighter circle, which helps with U-turns and multi-storey ramps.
