Date Rented: 4/28/15
Location Rented: DTW
Rental Company: National
Powertrain: 365 HP twin turbo 3.5L V6 with 6A
Highs: Turbo noises, nice midrange power. How awesome it is to cruise in 4 wheel low

Lows: The usual disappointing Ecoboost fuel economy.
Fun facts: You can manually select a 3rd gear start in 4-low.
Other notable cars available: new F150 (not ecoboost), Chevy Silverado and Dodge Ram (with Hemi). The Ram was my first choice but it didn't have the keys.
Would I rent again? as much fun as 4L was, I think I will have to pass.
