Wolf47 5pts I recently got to drive a Jaguar XF 3.0 as a loaner while my car was in the shop. I was impressed by the power available from just 3 liters. I imagine the 8 speed transmission helps make up for the 45HP loss. I also liked the start-stop feature. It seems to work well, with no delay in getting underway once the light changes. I note that the in city gas milage is very much better than in my 5 liter monster. The car also felt lighter, I wonder if it is. Nice job Jaguar!
