2015 Mustang 2.3 EcoBoost: super high-res engine images

by DrivingEnthusiast

We’ve just published 31 super high-res images of Ford’s new 2.3 liter EcoBoost engine from the 2015 Mustang on our parent site DrivingEnthusiast.net in our Ford engine section. The images are a maximum of 5400px wide in landscape with some portrait images in 3600px, so you’ll need to use an industrial strength browser (and if your browser automatically shrinks the image, turn off that option). You can then move the frame right and left and examine it in great detail.

Here’s one example, showing the back of the engine. Click on the image to get the full size image.

If you haven’t been following the information we’ve been providing about the 2015 Mustang, this post indexes everything we’ve written so far. The 2015 Mustang is a very significant new product by Ford, and rumor has it that the order books for North America open up on May 20th for deliveries starting in September.

The original Ford press release follows:

Horsepower Unleashed – Motivating the All-New Ford Mustang
December 5, 2013

New 2.3-liter EcoBoost® brings turbocharging to Mustang with exceptional power and torque and projected class-leading fuel efficiency
The all-new Ford Mustang offers a choice of engines available with either manual or automatic transmissions that make it a great all-around performer no matter how you mix and match.
Less is more, EcoBoost comes to Mustang

The new 2.3-liter EcoBoost engine brings turbocharging to the Mustang powertrain lineup. Designed to meet the needs of drivers looking for outstanding performance and projected best-in-class fuel efficiency, this EcoBoost engine has been developed specifically for Mustang. The intake manifold and turbocharger housing are optimized to provide better breathing and higher output in Mustang.

With a projected 305-plus horsepower and 300-plus lb.-ft. of torque, this EcoBoost engine fits the bill for a true Mustang powerplant.

“This EcoBoost engine delivers the healthy output that Mustang drivers expect regardless of the speed,” said Scott Makowksi, EcoBoost powertrain engineering manager. “This EcoBoost engine might be small in displacement, but it delivers where a Mustang driver expects it with a broad, flat torque curve and great driveability under any conditions.”

The newest member of Ford’s global family of EcoBoost engines, the 2.3-liter continues to take advantage of state-of-the-art technologies including direct fuel injection, twin independent variable camshaft timing and turbocharging to produce big-engine power and torque with improved fuel efficiency.

This is the first Ford engine to utilize a low-inertia twin-scroll turbocharger that provides quicker boost response while enabling lower emissions and improved efficiency. The cylinder head features an integrated exhaust manifold that separates the inner and outer pairs of cylinders into each inlet passage to the turbo.

Keeping the exhaust pulses separated from the next cylinder in the firing order eliminates mixing losses and maximizes pulse energy to the turbine wheel. The result is quicker torque delivery when the driver needs it for passing maneuvers and similar performance to a twin-turbocharger configuration.

The separated exhaust ports also enable the exhaust valves to stay open longer for reduced pumping losses that improve specific fuel consumption by about 1 percent.

With more than 305 horsepower and 300 lb.-ft. of torque pumped out from such a small engine, in a car where drivers are more inclined to use it, ensuring durability was critical. Enhancements to the Mustang EcoBoost engine to withstand the added stresses include:

  • Forged-steel crankshaft
  • Piston-cooling jets
  • Steel piston ring carriers
  • Premium bearing materials
  • Upgraded valve seat materials
  • Forged-steel connecting rods
  • High-pressure die-cast aluminum cylinder block with ladder-frame bearing caps
  • Deep-sump, die-cast aluminum oil pan
