The new Hyundai i20 Blue has joined the ever-growing ranks of tax-evading cars.

It has a CO2 output of just 98g/km, the lowest of any car the company makes.

The 1.4-litre diesel engine qualifies for free entry into the London congestion charging zone, and is completely exempt from road tax for the foreseeable future.

It is on sale now at an on-the-road price of £13,195.
