Lexus UX 300e vs Mercedes-Benz EQA

The Lexus UX 300e costs £4,000 more than the Mercedes-Benz EQA. On the headline specs that premium buys little measurable advantage - the two are closely matched on range, charging and space. The Mercedes-Benz EQA is not just cheaper - it also offers 50 kW faster peak rapid charging. On EVcarsguide's combined category scores, the Mercedes-Benz EQA comes out ahead overall.

The Mercedes-Benz EQA is £4,000 cheaper to buy. Running costs are almost identical - about £176 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Mercedes-Benz EQA comes out roughly £4,000 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 233 miles for the Lexus UX 300e and 219 miles for the Mercedes-Benz EQA - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. A rapid charge to 80% takes around 80 minutes in the Lexus UX 300e and 30 in the Mercedes-Benz EQA, so the Mercedes-Benz EQA loses less time at each stop.

The two are within 6 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 566 mm of total clearance for the Mercedes-Benz EQA and about 560 mm of total clearance for the Lexus UX 300e. The Lexus UX 300e also turns in a 1.0 m tighter circle, which helps with U-turns and multi-storey ramps.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Lexus UX 300e and 84% for the Mercedes-Benz EQA. That is close enough that capacity loss should not decide between them. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation. Both batteries carry a 8-year manufacturer warranty.
