JAGUAR has confirmed reports that it is investigating the introduction of diesel engines into its range for the first time. The manufacturer is looking into diesel options for its smaller cars, such as the S-type and forthcoming X400.

Trevor Crisp, Jaguar's chief engineer (powertrain), said: 'Diesels have become more and more refined and more appropriate for luxury cars and there is sure to be a significant market for a Jaguar diesel.'
