The car, to be named the Toyota Sai, will go on sale in Japan from October 20. The Sai will be the second model marketed as a hybrid-only offering under the Toyota badge, after the Prius.
Toyota did not say whether the Sai will go on sale outside of Japan with very few addition details being made public.
A dealer in Japan said the car will share the same platform and hybrid drivetrain as the Lexus HS 250h (pictured above) which means a 2.4-litre petrol engine hybrid system, similar to Camry.
Toyota has not yet announced pricing.
