Fresh from greeting the Citroen C-Zero earlier in the week, the Mayor, and green car advocate, welcomed the iOn after its UK-wide tour.
The four-door, four-seat electric car has visited Bristol, Birmingham, Manchester, Edinburgh, Teeside and London during its promotional tour extolling the virtues of its completely electric powertrain.
The compact car boasts a range of 93 miles on a single charge and can be charged in six hours or just 15 minutes with a quick charge facility.
Unlike previous electric cars such as the much-maligned G-Wiz, the Peugeot iOn is fitted with modern safety equipment and achieved a four-star rating in the EuroNCAP tests – higher than a Dacia Duster.
Johnson was impressed by the iOn at the event, saying: “I want London to be the electric car capital of Europe, so I am delighted that 2011 sees manufacturers accelerating their efforts to bring this technology onto the roads."
The Peugeot iOn and Citroen C-Zero are both based on the same platform and represent the first mass produced electric cars on the market in the UK.
Both cars are eligible for the UK government’s £5,000 Plug-In Car grant, which is included in the price to lease the cars for four years. The cars cost £415 per month before VAT to lease.
The Peugeot iOn costs around £2.50 to run for 120 miles – a huge difference to petrol and diesel cars amid rising fuel prices.
Perrys in Milton Keynes is one of only a handful of dealerships with trained sales, aftersales and maintenance staff capable of selling and servicing the electric cars.
The dealership, on Bilton Road, also boasts test cars and a charging station allowing customers the chance to test drive the next generation of electric motoring.
