90 minute drive to the lake (a lot less now with the TH....). I did the drive this past weekend and reset my average liters per 100 km gauge (sorry for all the metric my American friends) and doing 120 km/h on average I managed to get it to 13.5 liters per 100 km. Pretty impressive. My previous GC was a diesel and best I could do with it was just under 10 liters per 100km on the same drive. That said, I did not buy this car for its fuel efficiency. I don't think I'll ever use that gauge again and I'll just enjoy the vehicle for what it is.....pure ridiculous power. I'll buy my wife a hybrid to offset my carbon footprint..... No plans for anything aftermarket at this point. Still assessing but happy to hear what people think are the must do's after market. I really don't need more HP, but then again.....
