2021 Ford Bronco Fuel Economy Ratings

74

By @Laura #1976

Bronco Nation has received an advanced copy of the fuel economy ratings for the 2021 Broncos. Depending on your engine, transmission, and trim, all-new Bronco owners can expect a combined – gulp – 17-21 MPG. Ford vehicles are notoriously heavy, and the Bronco, built on the Ranger platform, is no exception.

2.3L and 7- or 10-SPD

As you’d expect, the best performing models are equipped with the 2.3L, 4 CYL engine and 10-speed automatic transmission as well as the 2.3L, 4 CYL engine and 7-speed manual transmission, both with a combined 21 MPG. This average will, of course, raise or drop per trim and packages applied.

2.7L

Owners of the 2.7L, 6 CYL engine, which can only be paired with the 10-speed automatic trans, can expect to see a combined 19 MPG.

FE Labels (MPG)

City Hwy Comb
2.3L Auto General (Base, Big Bend, Outer Banks) 20 22 21
2.3L Auto Black Diamond (non-Sasquatch) 18 18 18
2.3L Auto Sasquatch 18 18 18
2.3L Auto Badlands 18 17 17
2.3L Manual General (Base, Big Bend, Outer Banks) 20 22 21
2.3L Manual Black Diamond 17 19 18
2.3L Manual Badlands 16 18 17
 

2.7L Auto General (Base, Big Bend, Outer Banks, non-Sasquatch Black Diamond)

18 20 19
2.7L Auto Sasquatch (every trim w/ Sasquatch package) 17 17 17
2.7L Auto Badlands (non-Sasquatch) 17 18 17

 

The 2.3L manual transmission is currently offered without an option for the Sasquatch package, but it will be introduced later, and the fuel economy will likely follow the same pattern as the 2.3L automatic transmission with Sasquatch.

Typical MPG of the Class

The 2021 Bronco numbers, while expected by some, may be more uncomfortable to those used to, well, higher figures.

However, compared to a vehicle in its class, the Jeep Wrangler, these numbers are pretty typical. Still, the Bronco is outperformed.

Jeep Wrangler City Hwy Comb
2.0L Auto 2-dr 22 24 23
2.0L Auto 4-dr 21 24 22
3.6L Auto 2-dr 20 24 21
3.6L Auto 4-dr 19 24 21
3.6L Manual 2-dr 17 25 20
3.6L Manual 4-dr 17 23 19

 

Bronco’s Weight vs. Competition

When it comes to gas mileage, vehicle weight matters, and even 100 pounds of additional weight can make a noticeable difference in economy. Broadly compare the curb weight (when the vehicle is empty) of the Bronco to that of the Jeep Wrangler Rubicon, while remembering the vehicles have different armor, powertrains, and features:

Jeep Wrangler Rubicon 3.6L, 6-SPD manual
Curb Weight GVWR
2-dr 4,449 lbs 5,350 lbs.
4-dr 5,222 lbs 5,800 lbs.

Looking at the curb weight of the Bronco by trim and powertrain below will begin to tell you why the fuel economy is challenged. This is one robust (aka heavy) vehicle.

Is the Bronco Worth the Low FE?

With its powertrain built for off-road applications and an engine that passes truck durability ratings the 2021 Bronco is proving to be a thirsty utility. The fuel economy numbers may be disappointing for some and plain awful to others.

Even still, this vehicle, with its higher prices at higher trims, is targeted toward people with room in their budget for fuel, fun, and modifications. Our bet? Even consumers unhappy with the MPGs now will forget some of the pain at the pump once they encounter the capability and smiles per mile of the all-new Bronco.

  1. Well, at least I picked the most fuel efficient build. I sure hope gas prices don’t keep going up.

  2. I love these Ecoboost engines, but seriously, these numbers are pretty poor for this day and age, and yes, even for an offroad specific vehicle.

  3. While I didn’t expect a gas sipper I expected a bit better than these numbers with the standard 2.7L/Auto OBX. My 3.6L,19′ Wrangler Sahara Unlimited will do 25 mpgs on the highway at 70 without a headwind. And even with a headwind it will still do the listed 23. So yes, I’m a bit disappointed in these numbers. So much for the “Eco” part of Eco Boost. Our Bronco, like our Wrangler, will be used as a long road trip vehicle with some light off roading. I’m not gonna lie, if these numbers hold true it may be the deal breaker for me. I’m waiting on the official EPA numbers before that decision is made though. Damn I hope these numbers are wrong.

  4. The comparison with the Wranglers is not even. The Broncos are separated basically by final drive ratios. The Jeep’s don’t have any indication of a difference by gear ratio. Having said that, I’m not at all surprised by the numbers so they will make no difference to me.

  5. Why does the 2.3L non-Sasquatch Badlands get worse highway and overall mileage than the 2.3L Sasquatch? I would think the bigger tires, weight and gear ratio would make the Sasquatch less fuel efficient. For that matter, why does the Badlands get worse highway than city mileage? I realize the Ecoboost engines have auto start/stop happening in the city but I would expect one could cruise the highway in Eco mode with cruise control and get better mileage than with all the acceleration/deceleration one does in the city. I saw similar bizarre mileage numbers for the Ranger Tremor recently. These numbers appear to defy basic laws of physics!

  6. I’ve ordered a 2.7 OBX, standard suspension with rear locker & therefore 4.27 differential. I want to know the real world highway mileage, which in this report is 20mpg. Thats not good enough, my F150, (4wd crew cab) can get 24 hwy. And my real concern is Range. This is 400 miles max (20gal x 20mpg 4-dr), that is about 100 miles low. The problem is that the various trims lumped into 20mpg have a variety of hi & lo ratio differentials and tire sizes, all of which affect mpg. How much disconnect the 2wd setting gives to the rest of the 4wd drivetrain can also affect mpg as well. There’s so much i dont know. Thats the problem with buying a new-release vehicle.

  7. With this fuel economy it better be extra fun to make up the difference. If it really gets 13 with lots of short distance trips I might be better off getting another vehicle. Extremely dissapointing for a new highly anticipated off road vehicle. It should give at least what the Wrangler does. Ford this isn’t acceptable and probably a deal breaker. I ordered the Wildtrak.

  8. “…both with a combined 21 MPG. This average will, of course, raise or drop per trim and packages applied.”

    Nope, 21 MPG is actually THE HIGHEST combined average for all trim levels/engines. Be honest.

  9. My 2015 JK (2-dr) w 3.21 gears and 255’s from the factory never cracked 20, ever. Once I put a 2” lift in it and installed 285’s, it would barely crack 17 mpg. I’m not surprised. These vehicles are not light, are built to survive off-road, and are less aerodynamic than a standing cow. Anyone buying a Bronco (or a Wrangler), and expecting a stellar commuter car, is going to be disappointed. If I pull the trigger on my “reservation” (still want to see, sit-in, and drive one first, let alone purchase without the dealer conveniently tacking on extra profit $$$$ due to demand), it will be my fun car, driven for my personal satisfaction. Fuel economy be damned.

  10. Surprised at no break down of mileage between 2 dr & 4dr since there is a weight difference. Also, would be interesting to know if optional locking differentials (front and/or rear) made any difference at all. Would be nice to have detailed info for ordering options. You could manage choices between options when ordering – might make it slightly more fuel efficient – or not, driving probably trumps all equipment choice. Good to know though.

  11. These numbers don’t jive with the real world MPG of the 2.7 engine with 10 speed tranny, and I’m wondering if we’ll find that the Broncos really do better than these EPA estimates. A 4wd F150 crew cab has this combo and is quite a bit heavier. Why would it get better MPG than the Bronco with the same package?!? maybe final drive ratio, or ground clearance? I look forward to what the new owners have to say after some time on the road.

  12. Excellent beat ! I wish to apprentice whilst
    you amend your site, how could i subscribe for a blog site?
    The account aided me a acceptable deal. I were a little bit familiar
    of this your broadcast offered brilliant transparent idea

  13. I really like your blog.. very nice colors & theme. Did you design this website yourself or did you hire someone to do it for you?
    Plz reply as I’m looking to construct my own blog and would like to
    find out where u got this from. many thanks

  14. The other day, while I was at work, my sister stole my iPad and tested to see if it
    can survive a thirty foot drop, just so she can be a youtube sensation. My iPad is now destroyed and she has
    83 views. I know this is entirely off topic but I had to share it with someone!
