5.0L, 13L/100KM? i could only achieve that on the highways.
so, my understanding is, ecoboost is well enough for the daily drive, unless you really tow alot where V8 is more reliable. For daily commute, ecoboost is more suitable, low rpm higher torque give you better startup feelings after waiting the red lights.
Fuel Economy? the math is.....for every 100 km you could save 1L of gas in the city, or 2-3L during high way, so for the 1750 extra money, assuming the gas price is $2L, you may have to drive over 1750/2*100=87500 km to get the money back in the city,well the lower gas price the more mileage you have drive. so, it's your call.
I think you'll find that between the 5 litre and the EB the EB is the towing motor - has a better curve than the 5 litre.
Both are fine motors but I get the impression that, rightly or wrongly, a lot of people are saying their EBs aren't making great mileage in the real world - once they spool up you're using more fuel.
For a daily driver to be kept for many years I'd get the 5 litre.
If I was towing a lot I'd get the EB.
Five hundred K road trip last weekend mostly on the 401 at 130 kph my 2010 SCab 2WD XLT 4.6 made 11/100 for fuel. It would do 10/100 if I went slower. Round the west end as a DD it makes 16-17/100 depending how I drive it. You can only drive so slow in traffic before people run into you so you kinda have to balance that against saving fuel - I'd rather burn more fuel than have some tard in crapped out corolla rear end my truck.
Which brings me to cars. If you're big on fuel then maybe a truck isn't the vehicle for you but those little cockroach cars that people all drive now - they are soul destroying devices - you do not want to be in one of those - ever.
My advice is to drive whatever vehicle you like right now because life is short and some day you're gonna be dead for a real long time.
Might cost me a bit more for fuel but every time I get into this vehicle I feel good and that's worth a lot.
