PaulTan.org have published their "First impressions" review of the new Toyota Prius (3rd generation). 'The internal combustion engine of the new Prius is the 2ZR-FXE, an Atkinson cycle engine with 1.8 liters of displacement. This is up by 0.3 liters from the previous 2nd gen Prius 1.5 liter engine. The new engine puts out 99 PS compared to 77 PS from the 1.5 liter engine, and 143Nm of torque at 4,000rpm. Now why does a 1.8 liter engine put out so little power you ask? It's because of the Atkinson cycle - it's more fuel efficient however has less power density. The engine is now beltless thanks to an electric water pump. The combined output of the motor-generators produce 60kW and 207Nm of torque.'
