Deutz and Volvo Group are to continue their joint engine technology partnership, with a view to developing new low emission, fuel efficient engines. This new deal carries on from an agreement signed in 1998 for the development and supply of 4-7litre diesels. The agreement was concluded with a term of 15 years and is due to end in 2013, so the new supply agreement will come into effect from 1st January 2014.
