Not only does it have its name on the Toyota F1 car, but now the electronics giant also uses the eco-friendly Prius on its 300-strong fleet.
The firm has taken delivery of two of the cars and another is on order.
The F1 car packs a 3.0-litre V10 petrol engine and reaches peak power at 19,000rpm.
Its smaller brother has a 1.5-litre petrol engine under the bonnet, helped by an electric motor at low speeds, and runs out of puff at 5,000rpm. But it is a lot less nasty to the environment, producing a lowly 104g/km of CO2.
Panasonic’s fleet manager Sue Fuhr said: ‘Obviously it’s good to have an environmentally friendly car, and the congestion charge exemption is a bonus.
‘We were impressed with its performance and think its quietness will be good for drivers’ well-being, particularly in London.’
