The F-150 has a 23-gallon fuel tank size, just in the Regular Cab and SuperCab versions. There are optional tank sizes that follow the other trim levels of the 2021 F-150. The 23 gallons of gas may be equipped in the Regular Cab and SuperCab trim levels, but the SuperCrew® models use a 26-gallon tank size to fuel the 2021 F-150.
The Ford F-150 has more than 550 miles of driving range on one tank of gas in the standard model of the 2021 F-150. While that range of miles is the standard output, the list of Ford F-150 models means the maximum range will vary based on the engine and drivetrain that’s selected. The standard 3.3-liter V6 engine gets up to 20mpg city and 24 highway MPG, and the optional, more powerful 5.0L V8 engine gets up to 17 MPG in the city and 24 highway miles per gallon.
The Ford F-150 uses a 3.3L V6 engine which makes 290hp, certainly an eye-opening number. Similar to the amenities listed above, the engines and capabilities change with each trim buyers choose. A 2.7-liter EcoBoost® V6 produces 325hp and enhanced results in fuel economy. The available 3.5-liter EcoBoost® V6 engine makes 400 horsepower, and the larger 5.0-liter V8 engine produces 400hp. No matter which engine you select, an incredibly reliable drive follows. The 2021 F-150 continues to lead the charge for mixing durable performance and power, breaking the stereotypes of what trucks can be.

Maxwell ford has been my go to dealership for over 20 years. The is great and the speed of their quality service is fantastic. I have always been impressed with the Maxwell ford team.
took my truck in for some warranty repairs, and Lynne Thurmond was fantastic. She handled all the paperwork seamlessly and made the whole process completely hassle-free. Excellent service!
Service advisor was great even told me a way to save a few bucks on my next services.
Dealership has always treated us with courtesy and very knowledgeable about their work. We have been loyal customers for many years and we have purchased repeatedly from them for that reason.
Great price, service department courteous and helpful. Jordan explained everything well and treated me great. I was pleasantly surprised.
Even though I.was given different service advisors and the first assigned service advisor was not available many times. I was still given great assistance by other on-site advisors. In addition I was able to actually personally able speak with the mechanic who was working on my car.
Just tried to purchase a vehicle and this dealership wouldn't take my financial institution's buyer's check. I entertained their offer to go through their lenders and was offered a rate double what my financial institution offered. I was also not allowed to meet with the finance manager handling this. The salesperson Serena told me I was next to meet them then told me the rate and still refused to let me talk to the finance department.
Mr. Kenny Gonzales was one of the best sellers I have ever seen. They do what it takes to put you in the car you want and work with you. Thank you
John is a great guy he will make sure you are set and very attentive to your needs
El servicio fue muy bueno y muy antentto conmigo y mi mujer de nuevo muchas gracias
Always friendly and ready to help with whatever issues you have. The place is always clean and bright.
Called ahead, only to find out the vehicle I wanted was being sold to someone else. Found another one I liked, but they wouldn’t budge on price or offer what I wanted for my trade. They listed my trade for nearly double what they gave me and sold it within four days. I guess that’s on me.
The entire process took almost 8 hours, and despite having great credit, I was given a high interest rate. I ended up refinancing just two weeks later at a rate nearly 2% lower.
The salesman was nice, but overall, it was a frustrating ... Read More DealerRater - Oct 29, 2026
Took my truck in for service. Experienced Very friendly and courteous customer service. I also like the video the mechanic takes reviewing my truck and what he perceives is necessary.
Group 1 has always done a great job on any maintenance I’ve had done since 2019 when I bought the truck there too!
Devin was great. Helpful and smart. Determined to get me what I asked for and wanted!
I brought my 8000 mile mustang GT 5.0 to Lynne Thurmond and she had it handled quickly with great communication. I’m considering Group 1 as my home for all services with how positive the experience was.
We made our purchase of a used vehicle on Oct. 3rd. We were asked to review the dealership's services and our experience before we left. At the time, I was happy to give them a solid 5 star review, due to my experience that day; however, that's the initiation of the failing review. On the way home and days after, we ran into a tire issue and issue with the computer components. We called, left vm, and emailed the salesperson confirming coverages; here, even almost a month later, he has not responded. I also emailed the finance manager, as ...

Excellent staff and very helpful getting my car fixed. Kept in touch with me and had the car fixed promptly.
Professional team that ensured the customer is being served at all important points of touch in the process
My service advisor was Lyn and she's been amazing. Both proactive, and super helpful along the way
I have used Maxwell Ford for years and have never had any problems. The staff is great and service is excellent and done in a timely manner. My service advisor Ricardo kept me informed during the process. Lastly and very important to me, I truly appreciate the valet service provided. As a person with limitations this is a wonderful plus! Thank you for your excellent service!
Very unprofessional, promising to provide updates and not following through. Bad service equals No customers.
Excellent service and very quick to act on my car. Solid oil change experience. 5 stars.
Had clutch issues on bronco with only 32k miles. Dealership held my car for more than two weeks trying to figure out the cause of the issue, but Shawnie was very helpful keeping me up to date on status.
Overall, great experience! Jesus was my service rep and helped me throughout the process and communicated everything. Even when something was going to go slightly different than the original schedule, he was great at communicating right away with me and giving me options so I could pick what would be most convenient for me.
Lynne did a great job keeping us updated on the progress of our repairs. She went above and beyond.
Group 1 did a great job on my vehicle it is running like a new car. I’m am very happy with the work that was done on it. Thank you.
Rob was awesome and made the process quick and easy. Definitely recommend this dealership. Great job guys
Maxwell Ford has been servicing my 2015 F150 since new. I have always had excellent service.
Having my vehicle serviced at group 1 ford was convenient and hassle free, will definitely be returning for future services
I called about a recall notice. The phone was answered by a real person and I was quickly connected to Lynn in the service department. She was very knowledgeable and I was able to get my vehicle in that afternoon and it was finished the next morning. It was a software update for the PCM valve. A 35-point check was also done. As promised, Lynn sent me a text as well as an email letting me know the upgrade was finished and gave me a review of the 35 point check of my vehicle. When I picked my vehicle up, we ...

I have been doing business with Maxwell over 20 years and they do a great job.
Great customer service received by Jackie W and the entire staff every time I walk through the door.
As soon as I drove up into the dealership service center, I was acknowledged right away by one representative and then I asked for a representative Jason
Really good Communication ! Great customer Svc ! Nice place ! Fast Svc ! Kept me updated and good quality work!Defenitly a go back to!
Jackie W. is great. Got me in quickly and kept me informed. Work was completed in a manner and to my satisfaction.
Jackie Woira took my call, received my car and had the problem repaired quickly.. I will remember that and both refer people I know and use your service again because of Jackie
People I dealt with didn't jerk me around. They gave me a good price on my new truck. Felt like I was dealing with Honest people.
We had a great experience at Group One Ford, our salesperson Serena was great. I would definitely go back here for a future purchase.
The guy I talked to that sold me. The car was great. The guy who did the financing was pretty cool as well. I was under a lot of duress trying to make the purchase the long ride during rush-hour traffic kind of sucked. I barely looked at the car I did pop up in the trunk and make sure that works since the one that my mom has doesn’t work anymore. The interior was road kinda hard years of being in the hot Texas Sun, the window tint on the driver‘s door you couldn’t even look ... Read More DealerRater - Oct 8, 2026
Good service also great customer service as well. The staff is always a great help each and every time.
Kind, knowledgeable staff and quick service! I was able to use a coupon and get a great deal as well!
Quick professional and reliable I drive 70 miles to do my service on my Ford Mustang eco-boost just so I can get it done right
The service team is always very nice to work with and keep me updated on my car. The team has great processes and having the option to valet my car back to my home is so convenient. Thank you so much!
Recently bought a vehicle with Jose Ochoa one of the best customer service I had in a decade in a dealership buying a vehicle.
Great service. Really liked Shawnee who helped me. They did a great job and did the work quickly
Jason was able to get our inspection and recall repairs done same day and was great to work with!
Jackie and the service team always provide great service, the waiting room is nice and I am able to work while I wait. They keep me well informed and never try to sell me things I don't need.
My Service Supervisor, Ricardo Portillo, was very thorough, detail oriented, and attentive with keeping me posted on progress. In addition to my scheduled recall service, he did a good jobs explaining other service needs that I may consider while on site. Very organized process from start to finish!
I had visited a couple dealerships before this one and Group 1 was more invested in me wanting make the right purchase. Angel made it happen for me and I am grateful I was able to work with him. You rock Angel!
My service advisor was Jonathan Munoz and he was very helpful through the whole process
Very nice people and good workers I recommended I will take may car here again
Jackie was my advisor. She was very good at keeping me informed on the progress of my vehicle. It didn’t take long on the repair, I would definitely go back to get my vehicle worked on at Group1ford of southern Austin.
Technical Carlos Herrera make the perfect job on my truck - oil change and multipoint inspection
Serena made the purchase process very easy. Enjoyed working with her and the rest of the team.
Lynn is a great service advisor to work. Even though there is a closer Forfd dealership to where we live, I always go to Maxwell Ford to have Lynn take care of my Bronco services.
My first service visit with this truck. 5,000 mile oil change. Coupon for oil change reduced visit cost. Walk in service and I was out in an hour, and the waiting room was full. Service writer Johnathan was great. I also caught him signing to another customer. Said he learned in high school after failing Spanish. His skills are an asset to the dealership. I've been a Ford customer for over 48 years in Austin and many were Maxwell vehicles. Never an issue that couldn't be solved to my satisfaction!
My service Advisor Ray Luna kept me well informed of the progress of my vehicle. He gave me updates. He also informed me of the recommendations of the service crew. I will come back to have those repairs completed. I will ask for Mr. Luna. Thanks again, Ray! John
Great service & communication! Really appreciate their help and expediting of work. Would definitely go back
Jackie in the service department was extremely helpful and very professional. She made the entire experience easy and answered all of my questions.
Excellent service. Prompt, courageous and efficient. I am very satisfied with the level of service I received
They are great at communicating with you and getting approvals throughout the process so you aren’t surprised by anything at the end.
I must say that it has been a great dealership for me since I have bought most of our vehicles from Ford. Thank you
Friendly staff; fast service; great rewards program; and good advice on future and deferred maintenance.
This service person was great, awesome and provided excellent customer service. great time period for the service.
The car was great, process is typical. However, when I drove away with my new car I noticed it didn’t have floor mats.
They provided a great experience and were very professional. The waiting area was clean and comfortable.
Great service. Easy to schedule. The waiting room left something to be desired. Still, will definitely return.
Great and professional service, on time respectful and great attitude, and helpful, 100 recommend, thanks 👍
I worked with Robert to assess and resolve a maintenance notification I received in the Ford app. He worked hard with along with the mechanic to quickly get a diagnosis and replacement part installed so I could be back on the road.
Freddie and John are amazing at Maxwell Ford. Great customer service and urgency to take care of business
Fast, communication rocked, customer service and patience was great. Also professional and knowledgeable. I recommend!
Harrison, was terrific as my sales consultant. He addressed all of my concerns and made my visit as brief as possible.
Jackie is awesome. Work was completed timely. I will definitely be coming back here next time.
Incompetent service and horrible communication. Undelivered plans of service. Returning truck with delivery service and the driver noticed truck was worse than before.
Dropped it off at night. Call early in the morning. It was great and quick
The service advisor was courteous and prompt with helpful advice for my vehicle. Thanks R. Gryglew.
Friendly service and fast work time. Explained everything in the process. I Will go again
Jackie was right on top of my issues and her knowledge is always amazing, whoever was my Service Technician he or she was amazing in identifying all my issues and my vehicle is running in top form now that I got it back. From my initial quote communications were flawless and detailed. My car was ready when promised and pickup was seamless and quick.
The dealer team were so friendly..knowledgeable and took the time to work you...no pushy just very pleasant. The offices clean
Great customer service. Shawnie went above and beyond to provide a smooth and efficient service experience.
Great service, easy in and out. Techs are helpful and polite. Would recommend to anyone looking for Ford service
Ray my service provider was Great at communication. Fast service. Great place. Would recommend to everyone. Thank you
I had a great experience getting an oil change today. Hunter Coleman provided top-notch customer service. He was very kind, fast, and kept me updated the whole time. My car was ready quickly, and the service was smooth from start to finish. I will definitely come back. Highly recommend Hunter! Lastly, the coffee was very good.
Came in for an oil change. The adviser was professional and my service was completed within the timeframe given.
Great customer service and repairs. Dillon my advisor did an awesome job helping me out. I give him 2 thumbs up. Tank you
Freddie Seaboch was courteous, informative and knowledgeable. The staff also were attentive when pulling into the facility and didn’t leave me hanging like other dealerships.
This dealership is really easy going, the attention that is given is spectacular especially the way David treated us was great! Makes the process better, fast and not stressful, always gives us a good experience
Resolved all issues. Could be more willing to hand out loaner vehicles. Overall good Jod
I believe the gentleman’s name was Ricardo, but he was excellent and he informed me of what was happening and why. This may seem obvious and simplistic, but I personally really appreciate people to talk to you. They ask how your day is. They tell you the things that they found or didn’t on your vehicle. Because my truck is how I feed my family. So it may not seem like much, but treating someone in that manner goes a long way. So thank you.
I took my 2017 f150 5.0 for an oil change. The service was great, and they had me out in less than 40 minutes
Lynne Thurmond is always attentive to our needs. The service is done in a timely manner.
Fast friendly professional service performed on quick notice. Service advisor Ricardo Portillo exceeded expectations and would recommend him in future services.
Great experience as always. They’re quick, communicative and trustworthy. Great service and very friendly. Hunter was very helpful
Jonathan M was great! Great service and got me back on the road in no time!
Ray Luna in service delivered an amazing service experience. Very professional, friendly and knowledgeable. 10/10 experience thanks to Ray!
I went in for toe link replacement, which they did, but I also asked about a rear alignment. They diagnosed it and came back with about $5,000 worth of work that they wanted to do with it and would not do the alignment without the other work. It wasn't really explained to me why or how it made sense. Upon picking up my vehicle my advisor wasn't there so someone else checked me out. They were smug and rude and when they were having trouble starting my car (a Ford) they blamed me for not telling them how to ... Read More DealerRater - Jul 31, 2026
Jorge made buying our two new vehicles a great experience. He was friendly, knowledgeable, and easy to work with. He kept us informed throughout the process and made everything simple. Highly recommend asking for Jorge if you’re looking for a new vehicle!
They perform an authorized service without providing an estimate and review link for the requested service. They tried to only sell a bunch of unasked things only based on the miles not based on previous services. They were rude and yeilling and kicked me out I have spent roughly about $13k here and I am going to take my car elsewhere.
Robert was very professional and kept us inform on the status of our F150. Great customer services. I would definitely recommend your dealership.
