The car, which reaches British showrooms at the end of the year, returns 202mpg/71.51kpl combined and emits just 32g/km of CO2 - the best figures yet achieved by any plug-in hybrid.
The new Prius Plug-in Hybrid looks little different to the regular Prius launched recently, but it gets new LED lights front and rear. The car is 165mm longer than the outgoing model, 15mm wider and 20mm lower with an impressive aerodynamic drag factor of 0.24, delivered by such sophisticated measures as a double-bubble rear window and an automatic radiator shutter which closes when cooling air isn't needed by the engine.

Solar panels on the roof charge the battery when the sun shines and a gas injection heat pump system keeps the air conditioning working when the car is being driven in battery-only mode
There is also a larger, 8.8kWh lithium ion battery that, despite its extra capacity, takes just two hours and 20 minutes to charge. Toyota avoids quoting a kerb weight for its new model, but insists this has been “kept to a minimum”.
The Prius Plug-in Hybrid's petrol engine is an improved version of Toyota’s 1.8-litre four, with new big-capacity exhaust gas recirculation system and improvements to its combustion that lift its overall efficiency to 40%, making it, according to Toyota’s claims, the world's most efficient mass-produced petrol engine.
‘More engaging’ driving position
Toyota is at pains to portray the Plug-in Hybrid as a true driver’s car. It gets what designers call a “more engaging” driving position, a high centre console and the cabin layout of a luxury coupé, with a “dominant” centre cluster featuring 4.2-inch TFT screens and a wireless phone charging tray.
The driver-orientated theme continues with “more precise and responsive handling” thanks to a new double wishbone rear suspension, revisions to the familiar Prius’s MacPherson strut front end and a lower centre of gravity, which also reduces body roll, improves stability and sharpens the steering. The car is exceptionally quiet, Toyota says, helped by a new sound insulating laminated screen and special front window glazing.
