Toyota is enhancing its Auris line-up with the introduction of a new 1.33-liter Dual VVT-i 4-cylinder gasoline engine that delivers lower emissions, better fuel economy and improved power and torque figures compared to the 1.4-liter unit it replaces in Europe. The new Auris 1.33 Dual VVT-i will also be the Japanese automaker's first model in Europe to benefit from a Stop & Start system. Notably, the new 4-cylinder unit is 54mm shorter and 127mm narrower than the previous 1.4-litre VVT-i and weights 13kg or 28pounds less. The result is a four-cylinder engine that is roughly the same size as Toyota's three-cylinder 1.0-litre VVT.

The 1.33-liter Dual VVT-i delivers an output of 101HP and 132 Nm of torque compared to the outgoing 1.4 VVT-i's 97HP and 130 Nm. The engine is also matched to a newly developed six-speed manual transmission that replaces Toyota's five-speed gearbox. Albeit more powerful, Toyota claims that the 1.33-liter engine delivers 17% lower CO2 emissions (135g/km) and a 19% improvement in fuel consumption (48.7mpg UK / 40.5 mpg US / 5.8 lt-100km combined cycle) compared to previous 1.4-liter VVT-i unit.

Currently, the new powerplant is being built in Japan but from October 2009, the 1.33-litre Dual VVT-i engine will be produced at Toyota Motor Manufacturing UK's (TMUK) factory at Deeside in North Wales.

On-the-road prices for the new Toyota Auris 1.33 Dual VVT-i with Stop&Start start in the U.K. at £12,705 for the entry-level T2 three-door while according to Toyota, accross the range, prices are just £200 more than for the equivalent, previous 1.4 VVT-i models.
