Possibly the main factor in adopting electric vehicles is the purchase price – they cost more than their fossil fuel equivalents. The countries with the most sales also have the strongest subsidies.
Because it is quite new technology, and in the west the early models have been on the premium side of things, expect the price to gradually come down. Don’t be surprised if a $10K (USD) entry-level car is available in the next few years.
Here are the cheapest EVs currently, retail price before subsidies:
USA
Chevrolet Bolt $26,595 (was $36,620 in 2020)
Nissan Leaf $27,400
Tesla 3 $48,440
UK
Skoda CITIGOe iV £15,000
SEAT e-Mii Electric £16,000
VW e-UP! £16,000
