VW have recently announced that their 1.4 TSI will be replaced by the new 1.5 TSI which promises a 10% improvement in fuel ecomomy. The standard practice within the VW group is that the company which introduces a major improvement has sole use for approximately 6 months. By my estimation it is likely that the Q2 will only be supplied with the 1.4 TSI for a max of 6 months before it is superceeded by the 1.5.
