New 135mpg Prius becomes UK's cleanest petrol car, by miles

Mark Nichol

Toyota has announced the official fuel consumption and CO2 emissions figures for the new Plug-In Prius hybrid: 134.5mpg and 49g/km.

Those amazing numbers make the plug-in petrol-electric car the most efficient conventionally engined (ie. not pure electric) vehicle in the UK, by some distance.
