Mustang EcoBoost: Everything You Need To Know

Mustang EcoBoost The Complete Guide

There are some songs that transcend every decade. When Bob Dylan sang “Times They Are A-Changin’” in 1964, he was singing about the world that was changing around him, the heave and pull of old vs. new, and the changing of an era in our country. For those that have been following the car industry for the past 50 years, the change has been meteoric; with a shift from large, gas-guzzling, muscle-bound cars to smaller, lighter commuters, electric vehicles, and the wild popularity of the commuter and SUV mix known as the crossover.

While the Mustang has remained a popular vehicle over the years, changes in the regulatory landscape have forced manufacturers like Ford to begin the implementation of new, more efficient engine technology across their lineups to better cope with new, stricter fuel economy standards and consumer buying habits. Ford’s answer to the efficient muscle car? The Mustang EcoBoost.

Regulatory Changes and Muscle Cars

For muscle car fans, the formula is quite simple: rear-wheel drive, big engines, big power, and big fun. That “big engine” part? That was proving to be a problem for manufacturers like Ford who needed to bump their average fuel economy across their entire lineup to comply with government regulations and combat the looming global crisis of climate change.M/p>

The core of these changes has been the implementation of stricter and stricter fuel economy standards known as CAFE or Corporate Average Fuel Efficiency which states that car manufacturers must meet certain fuel economy averages across their entire lineup, by a certain date in the future. In 2011, President Obama signed an agreement with Ford (and other manufacturers) to increase their average fuel economy to 54.5 MPG by the year 2025.

If you think about Ford’s North American lineup for just a second, you’ll quickly realize the challenge ahead for the Blue Oval. Not only do they sell the country's best-selling vehicle, the F-150, but they also happened to have a legendary muscle car under their wings that was not exactly known for being the most fuel-efficient vehicle on the road.

The answer to this issue would not only bring stonking performance but provide Ford a performance platform for years to come.



Mustang EcoBoost Engine

EcoBoost Engine Technology

There are a variety of EcoBoost motors in the Ford family but the Mustang uses perhaps one of the most unique, durable, and powerful; the 2.3L. This engine has several advancements that make it incredibly unique among small-displacement turbocharged motors:

  • Large size (for a four-cylinder motor) that categorizes this as a “stroker”
  • Ford’s first “twin-scroll” turbo design in Ford’s EcoBoost lineup
  • Ford’s absolute commitment to engine material durability and design
  • The ease with which this engine can add more power with a simple tune or with upgraded parts

The 2.3L EcoBoost utilizes a twin-scroll turbocharger to provide power at ALL RPMs without resorting to the use of two-turbochargers. Those who’ve had the joy of driving older, turbocharged vehicles (WRX, we’re looking at you) know the terror of sudden and violent turbo lag. The twin-scroll design allows drivers to access peak torque at a much lower RPM while still providing the high RPM shove that turbos are known for.

The end result is an engine with 300+ horsepower that gets near 30 MPG on the highway. Yes, you read that right! It also happens to be nearly 150 pounds lighter, most of which is right over the front wheels, so it benefits from increased handling response.

Mustang EcoBoost Performance

The real story here is the benefits of lightweight and snappy, torque-rich engine performance from a relatively diminutive powerplant. Remember, this motor is right out of the Focus RS and it’s got the heart and soul of Ford’s Rally Cars baked into its heart. You can see for yourself, although this Mustang doesn’t sound like any Mustang before it, it sure moves like one!

Oh, and don’t forget that it’s pulling nearly 30 MPG on the highway; that’s the kind of performance you can use every day.

Mustang EcoBoost Performance Stats:

  • Zero to 60 mph: 4.9 sec
  • Zero to 100 mph: 13.5 sec

Modifying The Mustang EcoBoost

One of the best things about the Mustang EcoBoost is the ease of upgrading these turbocharged devils. The Ford Mustang experts at Steeda offer a huge selection of parts and accessories to turn your EcoBoost Mustang into a full-fledged performance machine that is equally brutal in a straight line as it is in the twisties. Remember, the 2015 Mustang was the first to introduce a fully independent rear suspension as standard kit and the lightweight EcoBoost motor is a perfect dancing partner in this willing combination.

Need proof of this incredible concept? Just check out the Steeda Q350 EcoBoost build for yourself.

We took a base EcoBoost and turned it into a track-focused monster that strikes fear into the heart of our competitors at the autocross. This EcoBoost Mustang is one mean, GT eating performance machine.

No matter which way you look at it, the EcoBoost Mustang represents the future of the Muscle Car. Sure, we’ll miss that characteristic V-8 rumble as much as the next guy but we won’t be missing much else, especially when we stomp the gas, feel the rush of the turbos and scream on to the next corner or down the strip!

This is a new era and Steeda can help make sure you’re ready!
