The recent engine upgrades include 'AFM'(Active Fuel management),
'VVT'(variable valve timing) and direct injection for best power, torque and
fuel efficiency.

Thinking of changing my TV.
We pulled our 2720 from Vancouver BC to Seattle this spring. Mileage is heavily dependent on hills, but I'd say it was in the 17-19 l/100km range. I suppose AFM does better, but a lot of people disable the AFM due to lifter failures causing engine damage.

I'm quite interested in Fords with the new Ecotech motors. The older ones had one set of fuel injectors directly into the cylinders. Consequently, the intake valves would foul up. The never ones have two sets of injectors, one set to keep the valves clean.
