WTCC to get small turbo engine formula
Any new model of car homologated from 2011 onward will be required to use the 1.6 turbo engine, although any current models still racing in the series will be allowed to continue with their existing units for at least the 2011 season. The FIA Touring Car Bureau will attempt to balance the performance of the new engine against the existing ones as long as both are running in the series.
The engine will also be introduced to rallying in 2011, with the single-spec unit used in any Super 2000-spec car across both disciplines.
