Replacement for Prius will be more powerful and efficient

In its efforts to come up with a car that blends economy, low emissions and performance at an affordable price, Toyota has decided to use a lean-burn 1.8-litre turbo engine. Meanwhile, the THS-II hybrid system will be upgraded with efficient lithium ion batteries, which will allow the electric motor to deliver greater performance because the cells recharge quickly and hold more power for longer.

To further improve efficiency, it's also thought that Toyota is considering a plug-in system, similar to that used on the Amberjac Projects Prius. The socket will allow owners to top up the battery when it's parked. Insiders at Toyota are excited about the newcomer, and are promising greater performance and super-low emissions for less than £20,000.
