Yes, the M135 is quite a performer in both performance and economy. I also do a lot of motorway trips, hence the 8.0l/100k average over 8,000k. In contrast, my previous car, an Audi 8P S3, averaged over 9.3l/100k over the same driving regime.
Oh, and for the record, my average speed over 8,000 k is 69kph
