Toyota has replaced the 1.4 liter VVT-i engine (4ZZ-FE) in the Toyota Auris with a new 1.33 liter Dual VVT-i engine (1NR-FE) that produces more power, more torque, more mileage, less CO2 emissions, yet has a smaller displacement and also weighs 13kg less despite having a more complicated Dual VVT-i drivetrain, thanks to pistons that are 36% lighter among other improvements. It’s also more compact, and Toyota claims it is the same size as the inline-3 1.0 liter VVT-i engine.

The new engine also has stop-start capability, which automatically stops the engine when the car is stationary, the transmission is in neutral and the driver’s foot is off the clutch pedal. When the driver presses the clutch, the engine is restarted, and Toyota claims a potential fuel savings and CO2 reduction of up to 15% thanks to this.

For a smoother restart, Toyota says this new engine is 9dB quieter and 0.3 seconds quicker to start compared to the outgoing 1.4 liter engine.

With the new engine also comes a new 6-speed manual transmission with ratios to match the new torque curve. Both the 5th and 6th gear are overdrive gears for a reduced cruising engine RPM during highway driving. Toyota says this new transmission can handle more torque than the outgoing 5-speed unit and is 11% smaller and has 15% less components despite having one extra gear ratio.

All these improvements come with a price of course. The new Auris 1.33 liter models are on average about £200 more expensive than the outgoing 1.4 liter models.

Pretty ridiculous to keep both engines and increase the access price to the car. In terms of performance (consumption aside) the engines are almostthe same. 4hp more!? 2nm torque more!? that's nothing. The consumption saving will come in grate share from the stop-start feature. I wonder if this couldn't be done in the current engines. The weight reduction is also a factor for consumption reduction but not that much. The 6 gears will reduce the consumption too but I wonder couldn't this be done in the current engines too? Resuming I don't think it's a big upgrade that is worth paying almost 400 euros more. I think this price should have been kept and the 1.4VVTi should have been "out of the market".

Built in Britain

From October 2009, the 1.33-litre Dual VVT-i engine will be manufactured at Toyota Motor Manufacturing UK’s (TMUK) factory at Deeside in North Wales. Almost €115 million has been invested in the plant in the past year to prepare for production of the new engine
