The Euro IV compliant engine could be a key advantage for Toyota in the fleet sector if it beats other manufacturers to supplying upper-medium diesels that meet Euro IV standards, the benchmark for the 3% company car tax supplement on diesels to be removed.
But after six months the 2.0D-4D will be replaced by the first engine to use Toyota D-CAT technology which cuts emissions substantially below Euro IV limits. Development data shows that nitrous oxide emissions are reduced by 50% and particulate emissions reduced by 80% when compared to Euro IV levels.
The effectiveness of D-CAT depends on availability of sulphur-free diesel, with less than 10 parts per million of sulphur.
The vast majority of UK forecourts only supply low sulphur fuel, although sulphur-free fuel is expected to be more widely available during 2003.
The Avensis will go on sale first in the UK and Ireland in March. It will also be available in 1.8VVT-i and 2.0D-4 (direct injection petrol) versions from March, with carbon dioxide emissions at 171g/km and 191g/km respectively for saloon and hatchback models.
Combined fuel consumption is expected to be about 39.5mpg for the 1.8-litre and 35mpg for the manual 2.0- litre. The D-4D has carbon dioxide emissions of 154g/km for the saloon and hatchback and 158g/km for the estate, with fuel consumption expected to be about 50mpg and 47mpg respectively.
