Frequently asked questions
Is the BYD ATTO 3 worth the extra £6,995 over the Renault Megane?
The BYD ATTO 3 costs £6,995 more than the Renault Megane. For that premium it adds 55 kW faster peak rapid charging, 70 kW more power and a 2.1s quicker 0-62mph time. On EVcarsguide's combined category scores, the Renault Megane comes out ahead overall.
Which is cheaper to own over 5 years, the BYD ATTO 3 or the Renault Megane?
The Renault Megane is £6,995 cheaper to buy. Running costs are almost identical - about £152 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Renault Megane comes out roughly £7,035 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the BYD ATTO 3 and Renault Megane like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 263 miles for the BYD ATTO 3 and 255 miles for the Renault Megane - 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 35 minutes in the BYD ATTO 3 and 24 in the Renault Megane, so the Renault Megane loses less time at each stop.
Which is easier to park and drive in town, the BYD ATTO 3 or the Renault Megane?
The Renault Megane is the easier car for tight UK car parks: it is 107 mm narrower than the BYD ATTO 3. In a standard 2,400 mm bay that leaves about 632 mm of total clearance for the Renault Megane and about 525 mm of total clearance for the BYD ATTO 3.
Which battery will hold up better as a used buy, the BYD ATTO 3 or the Renault Megane?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the BYD ATTO 3 and 90% for the Renault Megane. That is close enough that capacity loss should not decide between them. Both use LFP-type cells, which are happy charged to 100% every day. Both batteries carry a 8-year manufacturer warranty.
