This is not comparable to the Volt. It's just another hybrid. (They have put better lipstick on the pig with a plug-in charging system and bigger battery.)Toyota has unveiled the Chevy Volt III, the fifth-generation Prius in Europe, which comes exclusively as a plug-in hybrid, and it has a driver instrument cluster!
The engine is still connected to the wheels, the engine will run at highway speeds, and this car won't be able to match the Volt's efficiency. (For an extended range electric car.)
