The Base Fiesta S is aimed at economy minded customers. Air conditioning, an auxiliary input jack and a 4-inch touch screen are standard, while the car can be optioned with a nicer sound system, keyless entry and auto locking doors. The mid-level SE models include these items as standard, while also adding the latest version of Ford's SYNC system, power windows, a trip computer, heated side mirrors and cruise control. Top of the line Titanium Fiesta add features that are unusual in the subcompact market, including heated leather seats, SiriusXM radio, pushbutton start and a perimeter alarm system. The Ford Fiesta's 120-horsepower, 1.6L 4-cylinder engine features Twin Independent Variable Camshaft Timing, which enables smoother low-rev torque while also maximizing fuel economy, all with an EPA highway rating of 40 mpg (when equipped with the Super Fuel Economy package). A 5-speed manual transmission is standard, but the available 6-speed PowerShift transmission is unique in the class; the twin-clutch automated manual transmission helps improve both fuel economy and performance versus a traditional automatic. In most other ways, the Fiesta is laid out much like other subcompacts. The suspension, which has struts in front and a twist-beam axle setup in back promises a sportier driving experience than other economical cars. Although the interior layout of the Fiesta, available as either a hatchback or 4-door sedan, is much like other cars of its size, Ford offers upgraded materials and trims inside, as well as a wide range of textures and colors. The result is a more premium, sporty feel throughout the cabin. Upholstery choices include cloth, leather, or perforated leather with contrast piping, while available ambient lighting includes a choice of seven different colors. Ford has made an effort to keep the interior especially quiet with the use of foam baffles inside the pillars, as well as additional sound insulation behind the instrument panel. Inside, the Fiesta comes with bucket seats in front and a 60/40-split bench seat in back, which can be folded forward in part or in all to expand cargo space. Front seats are designed for a wide range of sizes, and the steering wheel tilts and telescopes. Cupholders are adjustable, while several smaller bins are provided for odds and ends. Safety is addressed with a stability control system, a tire pressure monitoring system and a variety of airbags. Front side airbags, side curtain airbags and driver's knee airbags all come standard across all Fiesta trims.
