Toyota has announced that its new Prius will cost £18,370-£21,210.
Although there is more standard equipment than on the current model, the price of the T3 and T Spirit models stays the same, while the T4 has risen by £835.
Toyota says its Hybrid Synergy Drive now delivers 24 per cent more power, yet the unit is more compact and lighter than before, making the Prius faster.
The new Prius is more spacious than the old car, with more rear head and legroom. The boot is also larger thanks to the smaller hybrid battery unit.
CO2 emissions have been cut to a market-best 89g/km and fuel consumption has improved by 10 per cent to 72.4mpg.
