Series II Manual SV6
I have had an MY09 SV6 manual sedan (for 30 months, 75,000 km) and now a Series II MY11 for two months and approaching 6,000 km.
Once run in, the MY09 generally returned between 10.5 and 11.0 L/100Km around town (average speed between 40 and 50 Km/hr), and around 8.0 on a trip averaging around 90 Km/hr. In that vehicle, the trip computer was optimistic on fuel consumption by about 3%.
I have yet to take the Series II on a trip yet, but the trip computer is showing 11.5 L.100Km at an average speed of about 40 (over that last 3,000 km). However, actual calculations show the real figure at 11.0. When run, in I would expect about 10.5 around town, and am hoping for better than 8.0 on the highway.
I could see a figure of around 13L/100Km if driving was only in peak hour inner city traffic. Otherwise I would expect much better.
