Summary Already among the most economical and efficient in their respective classes, Vauxhall's ECOTEC engines have been comprehensively up-graded for 2001. The result is even lower exhaust emissions and fuel consumption combined with higher power output and torque. Vauxhall has worked on a number of changes and additions to its engine line-up, one of the most significant being the extra applications for its acclaimed all-aluminium 2.2 litre 16v. This engine – which already powers the Astra Coupé and VX220 – will become available for the Astra, Zafira and Vectra models.
