Ultra low emission vehicles (ULEVs) are the greenest cars on the market. Whether it’s a 100% pure electric, plug-in hybrid or hydrogen fuel cell, these cars have lower running costs, emit little or no emissions, benefit from zero or low road tax and are exempt from the London Congestion Charge.

To qualify as a ULEV, cars must emit less than 75g of CO2/km from the tailpipe and be capable of operating in zero tailpipe emission mode for a range of at least 10 miles.

We’ve chosen 22 of the best electric, plug-in hybrid and fuel cell cars. All prices quoted include the Government Plug-in Car Grant of £2,500-£4,500 where cars are eligible. Sadly vehicles costing more than £60,000 do not qualify for the scheme….
