In true teaser-image fashion it doesn’t give much away, showing only a darkened silhouette and a new tail-light design.
Updated, more horizontal rear lights look to replace the more vertical lights showcased on the hybrid Prius, which was unveiled just last year.
Toyota was unable to confirm exactly what is coming to the new model, but Autocar expects it to be a new plug-in variant.
The outgoing plug-in model uses a 132bhp, 1.8-litre 16-valve DOHC engine with VVT-I and an e-CVT transmission. The powertrain is capable of accelerating the car from 0-62mph in 11.4sec and on to a top speed f 111mph. Expect improvements all round and less than 40g/km of CO2.
Mechanical specifics in terms of its plug-in powertrain have yet to be confirmed, but it is expected to feature ithes current hybrid electric motor along with a new, larger battery.
Whether the design updates are intended to distinguish the plug-in model from its hybrid sibling or whether the styling will eventually transfer across has yet to be confirmed.
A direct rival to a new plug-in Prius would be the Chevrolet Volt. It is powered by two electric motors and offers a range up to 52 miles of pure-electric running or 420 miles from a full electric charge and a full tank of fuel.
