Torture Tests Continue for the Ford F-150 Ecoboost Engine

The 2011 Ford F-150 EcoBoost™ “hero engine” recently ran for 24 hours at Homestead-Miami Speedway as another demonstration of the durability of the new 3.5-liter truck engine. The truck towed a trailer at full throttle with two NASCAR® Sprint Cup Ford Fusions weighing 11,300 pounds around the site of the NASCAR Ford 400 season finale, Homestead-Miami Speedway.

A top speed of nearly 100 mph was attained, with the F-150 EcoBoost pounding out average speeds above 80 mph with the fully loaded trailer on the 1.5-mile oval track. The truck and trailer ran for 24 hours, stopping only for fuel, driver changes, to check temperatures, inspect truck tires and replace trailer tires.

While at Homestead-Miami Speedway, the 2011 F-150 EcoBoost:

  • Turned 1,061 laps
  • Compiled 1,606 miles
  • Had a fast lap of 99 mph
  • Averaged 82 mph

In addition to demonstrating the performance of the 3.5-liter EcoBoost, the Homestead-Miami track also proved to be a showcase for the standard trailer sway control. Even with strong wind gusts combined with variable banking of 18 to 20 degrees in the turns, trailer sway control helped keep the maximum load under control.

Trailer sway control works in conjunction with AdvanceTrac® with RSC® (Roll Stability Control™) to determine if a trailer is swaying and takes immediate measures to help the driver bring the vehicle and trailer under control. The system is automated and requires no driver interaction.

This is the latest test in a series of web-based documentaries to demonstrate the durability of the new 3.5-liter EcoBoost truck engine available in early 2011. You can click here to see more on these test, as well as the videos in the series at

The high-speed maximum towing test is the current phase of a testing program that started when a randomly selected EcoBoost engine endured the equivalent of 150,000 miles or 10 years’ use on the dynamometer, replicating the duty cycle of the harshest-use customer. After the “Dyno Stress” torture testing, the engine was installed into a new 2011 Ford F-150 to work as a log skidder in Oregon, dragging logs weighing up to nearly five tons. You can read more about that by clicking here.

Next for the engine will be a towing challenge where the 2011 Ford F-150 EcoBoost will take on the best the competition has to offer. Finally, the same EcoBoost truck engine will be raced at the Tecate SCORE Baja 1000.

EcoBoost is fundamental to the Ford strategy of providing technologically advanced, high-output, smaller-displacement powertrains that deliver uncompromised performance and fuel economy. EcoBoost engines deliver fuel economy gains of up to 20 percent and reduction of CO2 emissions of up to 15 percent, compared with larger, less-efficient engines.

In addition to turbocharging with direct injection, Ford engineers have enhanced the EcoBoost technology capabilities by adding variable valve timing and precisely controlling all aspects of the engine. Ford has at least 125 patents on its EcoBoost technology.

The 2011 F-150 EcoBoost will be available in early 2011.

Matt Sahd Jeff the turbos are cooled very well, they are water coooled. and after the tests Ford ran it would seem like they designed the cooling system for them very well.

Philip T I drove an F150 EcoBoost last night and I was very impressed. I hope this engine finds its way into the expedition!

Bruce Taylor I just happened to stop by a Ford dealership Monday afternoon and the salesman noticed that I was driving a Silverado. He invited me to a special showing and test drive on Tuesday. I did go to just look but then I noticed the Ecoboost engine was a V6, something I didn"t know. So i decided to test drive one. I can only say this. I was so amazed at the 2011 F-150. The truck was so quiet and rode rode so smooth. It drives much smoother than my wifes Cadillac. The power was just unbelievable. I will honestly say, it was the best auto or truck I have ever driven. I have owned GM vehicles and trucks for 35 years. It is hard for me to admit but driving my 2007 Silverado home was disapointing. It just doesn"t compare! So I will close with this. Ford keep up the great work. The competitors are not even close to this truck. If it was somehow possible, after 35 years I would switch. Thanks for the drive, Bruce Taylor Oak Creek, Wi

Witts End Being a avid Ford fan, my thought is: 82 MPH with 11,300 LBS = ? MPG. My 2005 F-350 does it at about 9.6 MPG

Jeff This is a fantastic feat of engineering on a turbocharged gasoline engine. What measures were taken to make sure the oil lines running through the turbo don't coke up with all that heat?
