The new Prius will bring gains in fuel efficiency and CO2 emissions of around 18%, the Japanese firm has confirmed.
Toyota is adopting styling cues from the Mirai fuel-cell vehicle for the latest generation of its hybrid, which made its public debut at the Frankfurt motor show. Now the company has released more technical details in the build-up to the car's debut in its home market, where Toyota hybrids regularly fill two of the top three positions on the sales charts.
The powertrain is an updated version of the existing combination of a 1.8-litre petrol engine and an electric motor, featuring a more compact nickel-metal hydride battery pack that's quicker to charge. The combustion engine produces of 97bhp and 105lb ft, while the electric motor brings 71bhp. Toyota also says it has revised the Prius's regenerative braking system, introducing a new active hydraulic booster that's designed to be quieter and give a more natural feel to the brake pedal.
Toyota hasn’t issued any definitive CO2 emissions or fuel economy figures - it says EU NEDC numbers will be released at a later date - but it has revealed that this Prius will bring efficiency gains of 18% over its predecessor. That's the biggest jump between generations in Prius history, and could give the car CO2 emissions and combined fuel economy of 73g/km and 85mpg.
The new Prius is 4540mm long - an increase of 60mm over the outgoing model - and has the same wheelbase of 2700mm. The more compact powertrain has allowed the auxiliary batteries to be moved to the engine bay and the hybrid batteries to be relocated to below the rear seats. These measures and the slightly longer rear overhang give the new Prius improved boot capacity, up from 445 litres to 502 litres.
