The Mustang EcoBoost’s 2.3-liter direct-injected and turbocharged mill produces 310 hp and 320 lb-ft of torque, and it can be paired to a six-speed manual or a six-speed automatic gearbox. The manual-equipped example we tested is EPA-rated at 22/31 mpg city/highway. Unlike most modern turbocharged engines that tend toward the quiet side, the EcoBoost engine makes cool turbine sounds once you hit the gas to accelerate.
On the road, you’ll immediately notice that the car has lots of midrange torque but not much else. Below 3,000 rpm, there’s little power available due to a prodigious amount of turbo lag, but once it gets going, there’s plenty to work with. Rev the car above 5,000 rpm, though, and all you’re making is noise because it loses steam. Switch the drive mode selector over to Sport, and you get slightly improved responses from the engine and throttle, but the turbo lag is still there. Keep the car in its sweet spot between 2,500 to 4,500 rpm, and you’ll be able to get the most out of it. Should you decide to take the car for a track day, there’s a Track mode that turns off the ESC and lets you really push the car to its limits.
