TOYOTA claims its rapid advances in clean engine development have left its market rivals standing.

With the introduction of a new 2.0-litre D-4D engine into the Corolla range, Toyota becomes the first manufacturer to provide a complete engine line-up in the two principle volume market sectors (C and D) which is fully compliant with Euro IV emissions standards.

That’s good news both for the environment and for drivers, who can enjoy cleaner performance, increased fuel economy and lower company car tax with no loss of driving performance or pleasure.

The launch of the engine means that all engines - petrol and diesel - in both the Corolla and new Avensis now meet the stricter emissions criteria, a full 18 months before they are due to come into force.

Delivering this level of clean performance so early provides excellent cost of ownership benefits for both private and company car drivers. In developing its lower emissions technology, Toyota has not had to compromise on performance, driveability or economy: all engines provide a strong balance of power, flexibility and competitive fuel consumption.

Where fuel economy is concerned, the new 114bhp 2.0-litre D-4D unit takes the Corolla to new heights, with a combined cycle figure of 50.4mpg for the three-door models.

Built at Toyota’s Deeside factory, the engine is being offered in the Corolla alongside the established 89bhp D-4D unit. The 109bhp diesel engine, previously available only in the five door T Spirit model, has been deleted from the range.

T2 five-door £13,300; T3 three-door £13,800; T3 five-door £14,300; T Spirit five-door £15,300.
