Changes to the Central London Congestion Charge announced today open the way for even more Toyota vehicles to travel in the capital for free. From 27 October, cars in bands A and B for Vehicle Excise Duty - those emitting less than 120g/km of carbon dioxide - will receive a 100 per cent discount.

As a master of small car design and clean engine technology, Toyota is well placed to benefit from the adjustment. All Aygo and diesel-powered Yaris models will join the hybrid power Prius as charge-busting vehicles.

In all there are 35 Toyota models that are charge-exempt, when different body styles, transmissions and specifications are taken into account. And the even better news is that Toyota's product strategy promises more low emissions models in the not-too-distant future.
