Toyota Prius drivers are set to avoid a price hike in the London congestion charge daily rate from £5 to £8 on Monday.

The Prius is exempt from the toll due to its environmentally friendly engine. The annual saving, after the rate increase, for Prius drivers travelling into London, Monday to Friday, now equates to £2,080.

Toyota expects to sell over 3,500 Prius in the UK this year, more than doubling the 1,588 units sold in 2004.

On-the-road prices for the Prius start at £17,545.
