Could this be the next SVO or GT350 / SVT S550 Mustang? Pay close attention to the above video and tell us what you hear!
Spotted on the streets last week was this 2015 Mustang. While it seems at first like just another Ford test mule putzing around Dearborn, it gives off an exhaust note that should have you wondering what motor is under the hood.
What Engine is it?
With such a short-lived exhaust note, it’s very difficult to tell if it’s a 4, 6 or 8 cylinder motor. We do know a 2.3L EcoBoost is coming, the Coyote v8 and 3.7L V6 from 2014 will be back and Ford has something in store for a GT500 replacement. It’s most certainly not the Coyote and one would obviously imagine this is not the supercharged V8 Trinity motor found in the current GT500. That leaves the 2.3L turbo 4, naturally aspirated 3.7L or a new engine variant as the only probable possibilities.
Taking those options one at a time, the 2.3L EcoBoost engine makes sense, at least after you first hear it. Two reasons this 2015 Mustang might not sound like the previous EcoBoost S550s we’ve seen but still be that same motor: 1. The exhaust seems to be a modified quad-tipped system that certainly could change the sound and 2. They could be retooling the 2.3L and creating a higher output, SVO version of the current EcoBoost model. There also appears to be A-pillar gauges that could indicate the car is boosted.
The Flip Side: Taking the devil’s advocate side of that argument, you simply don’t hear the turbo–it does sound like a naturally aspirated vehicle. Those gauges could also simply be performance monitoring additions made by Ford’s testing team for what purpose we won’t know.
The Flip Side: It’s hard to argue with someone saying there’s a V6 under the hood of that Mustang. Frankly, it’s entirely possible this is simply a base model 2015 Mustang, but then why would Ford still be testing that motor this late in the game? It’s also pretty quiet at idle and hits high in the rpm band pretty fast…food for thought.
That leaves what appears to me to be the most likely scenario: Ford is testing a new motor. By my untrained ear, and considering the briefness of the video, this could be almost any engine–4,6 or even 8 cylinder–but does not sound turbo’d. My guess is it’s a N/A car. At this point, you’ve probably heard a whisper or two about Ford working on a flat plane crank (FPC) V8 engine nicknamed (or codenamed, depending on who you ask) “Voodoo.” We briefly covered it back when Ford accidentally leaked the 2015 engine options. If you’ve heard a few FPC V8s before, you wouldn’t rule it out as a possibility, especially given the unique exhaust setup seen on this test mule.
Enough theorizing–tell us what engine you think this is in the comments below.
