There are five trim levels for the fastback: V6, EcoBoost, EcoBoost Premium, GT and GT Premium. The convertibles simplify things by only offering V6, EcoBoost Premium and GT Premium trims.
V6 Mustangs offer 17-inch wheels, HID headlamps, power mirrors, a leather-wrapped steering wheel, power windows and door locks, a 6-speaker stereo with Ford's SYNC system and a rearview camera.
EcoBoost models come equipped with Ford's 2.3L 4-cylinder, which is more fuel efficient than the V6 while still making comparable power. EcoBoost models' standard equipment includes 18-inch wheels, a 6-way power adjustable driver's seat and power adjustable passenger seat, and an intelligent key.
The EcoBoost Premium trim adds dual-zone climate control, heated mirrors, additional exterior lighting and a 9-speaker stereo with SiriusXM satellite radio compatibility. A Pony Package is offered on this trim.
The Mustang GT and GT Premium come similarly equipped to the EcoBoost trims, though of course GT models are powered by fire-breathing V8 engines rather than fuel sipping 4-cylinder turbos. Several performance options and packages are available, including a range of rear axle ratios, several wheel choices, and Recaro sport seats. A California Special Package adds 19-inch ebony wheels, ebony suede seat inserts with red stitching, special door panel inserts, an aluminum dashboard finish and more.
