A raft of changes have been made to the Prius, Prius Plug-in and Prius+ models, including testing using the new WLTP emissions regime. The updated regulations mean that the Prius Hybrid no longer qualifies for free passage into London’s congestion charging zone, which will be a big blow to London customers. CO2 emissions rise to 78g/km for cars with 15-inch wheels (up from 70g/km) and cars with 17-inch wheels now emit 82g/km of CO2, where previously the figure was 76g/km. Other changes include a rain sensor on all versions except the Active grade, and a leather steering wheel on all versions. Active and Business Edition models now feature a newstyle for their 15-inch alloy wheels, and these can be fitted as an option for Business Edition Plus and Excel versions in place of the larger 17-inch items. Prices start at £24,240 for the Active and rise to £28,345 for the Excel with 17-inch alloy wheels. For Prius Plug-in buyers there’s no specification or price changes, but CO2 emissions rise to 28g/km, up from 22g/km. The biggest changes are reserved for Prius+ buyers, with Toyota’s Safety Sense system now fitted as standard. This includes adaptive cruise control, lane departure alert, automatic high beam for the headlights, road sign assist and a pre-collision system. The line-up has been reduced down to two versions – Icon and Excel – with the former now producing CO2 emissions of 106g/km (up from 96g/km) and the plusher Excel edition now stands at 112g/km, where previously it was 101g/km. Changes to the badges on the back of the car includes the removal of the Toyota name, the addition of a new hybrid logo and the Prius+ nameplate moves from the right to the left-hand-side of the car. Icon models lose rear privacy glass, heated front seats and half leather upholstery, and head-up display is no longer available on the Prius+. Prices start at £27,825 for the Icon, an increase of £165, while the Excel version is now £30,170, a rise of £240.
