VOLKSWAGEN will debut its first Euro IV diesel in the new Touran compact MPV next year as the company promises lower company car tax liability than rivals.

Two diesel models, a 100bhp 1.9TDI and a new 136bhp 16-valve 2.0TDI, will be compliant with Euro IV emissions rules from its launch next summer, so removing the 3% benefit-in-kind tax supplement levied on diesels.
