It's also the reason why the 7.3 works so well in the Super Duty versus using an Ecoboost engine.

10.3:1 compression ratio for the 2.7, 12:1 for the 5.0 so the towing fuel economy doesn’t surprise me, with no boost. Especially at altitude, where TFL tester them), where the naturally aspirated engine will run lean with a lower density. I think the 2.7 will be a lot of fun in the Bronco though. Supposedly the Warthog will get the 3.0 or 3.5.
