No, that would be the TDi. The LCR will happily rev to the red line.
As has been said, they're not really comparable, an LC180 will smoke (excuse the pun) a standard TDi 150 everywhere, and it'll still take out a stage 1 mapped TDi at higher speeds. The LCR is an another league.
You need to be doing upwards of 20k miles a year for the Economy of the TDi to become a major factor. They're more expensive to buy because Joe in the street isn't intelligent enough to work out that paying £1500 extra up front for the diesel is going to take years to pay itself back when you're only doing 500 miles a month.
