bye bye v6
The Mustang GT’s 5.0-liter V-8 also has been revised. Mustang chief engineer Carl Widmann states that the only truly carryover piece from the current 5.0-liter is the crankshaft. Along with a new fuel-delivery system employing both port and direct injection, the updated V-8 also revs higher than before. A quad-pipe exhaust system replaces the current dual-pipe unit, and, as on its fiercest competitor, the Chevrolet Camaro, there’s an optional variable exhaust system that keeps things quiet at lower rpm but amps up the noise courtesy of valves that open when heavier throttle is applied.
Both 2018 Mustang engines are mated to either an upgraded six-speed manual transmission or a new, optional 10-speed automatic. In the case of the V-8, the manual transmission also incorporates the current GT350’s clutch and dual-mass flywheel to improve shift action. Additionally, all 2018 Mustangs are treated to retuned dampers, new anti-roll bars, and a “cross-axis joint” in the rear suspension, while cars equipped with the Performance package gain the GT350’s electronically adjustable magnetorheological dampers, another piece of tech already on the Camaro.
The biggest visual change is for cars equipped with the Performance package, which inherit a gaudy new rear wing. Although Ford notes that the Subaru WRX STI–like piece has been thoroughly tested in the wind tunnel, the company will allow Performance package buyers to opt out of the big trunk-mounted picnic table. The rest of the Mustang’s exterior updates are more restrained. Ford says the front fascia cribs styling details from the Ford GT supercar, although we’re still searching for the likeness. Redesigned headlights and taillights use LED technology, while the hood, rear fascia, and rear trunk appliqué have been lightly retouched. The overall look is less retro but still inherently Mustang
