May 2020, the second month of the coronavirus lockdown in the UK, was the worst May since 1952. Only 20,247 new cars were registered (89% less than in 2019).
On the positive side, the plug-in electric car sales decreased by "only" 25.4% year-over-year to 3,249, thanks to an outstanding 21.5% growth of all-electric cars (the PHEVs were down by 65.1%). The overall plug-in market share was 16%.
The main explanation behind strong BEV sales is that there were a lot of pre-orders of the latest models, which were delivered to customers.

Top models
The list of the top 10 passenger cars in May, just like in April, is led by the Tesla Model 3 (852)! It's a great score, although we are aware that those are cars shipped from California before the pandemic.
We are sure that some other plug-ins also might be relatively high, but there is no way to identify them solely by the name (like the Vauxhall Corsa-e - part of Corsa).
