Ford's small-car family dresses up a bit more for 2007, but the Focus retains its affordability and fun-to-drive qualities. Leather sport seats with contrasting leather inserts are newly available, either as a separate option or as part of the new Interior Upgrade Package. The package also includes a two-tone, leather-wrapped steering wheel, a satin finish for the center stack and instrument panel, and black sill plates. Two new Street Appearance Packages add a more aggressive, tuner look to the Focus. Both bring a spoiler in back, along with a bright exhaust tip, body-color front fascia with fog lamps, and body-color rear bumper trim. The Focus's sound systems have also been revised for 2007 to include a standard single-disc, MP3-capable CD player on all models. The optional six-disc changer system now includes steering wheel-mounted audio controls. There's also a Sony audiophile system with an eight-inch subwoofer available on all but the base S model. Focus S, SE, and SES models are powered by a 2.0L four-cylinder DOHC engine making 136 horsepower (130 horsepower with the cleaner PZEV version sold in CA, NY, MA, VT, and ME). The ST model steps up to a 2.3L version making 151 horsepower. The 2.0L models come standard with a five-speed manual transmission (a four-speed automatic is optional), while the 2.3L ST is only offered with the five-speed manual. Fuel economy ranks high with all Focus models; it ranges up to 27 city, 37 highway, with the 2.0L engine and five-speed manual. The Focus runs the gamut from frugal and basic to very well equipped. The base S model only comes with manual windows, locks, and mirrors but does include an MP3-compatible CD player and rear wiper/washer on hatchbacks and wagons. The SE adds popular equipment like power locks, windows, and mirrors; keyless entry; and air conditioning; while the SES includes alloy wheels, a rear stabilizer bar; cruise control; an overhead console; a tachometer; and a tilt/telescope leather-wrapped steering wheel. At the top of the range is the sporty ST, which, besides the more powerful engine, adds four-wheel anti-lock disc brakes, a performance-tuned suspension, a special grille and rear fascia, a chrome tip for the exhaust, heated exterior mirrors, sport bucket seats; and a stitched, leather-trimmed steering wheel and shift knob. Each model is available as a two-door hatchback, four-door sedan or four-door hatchback, while the wagon is only offered as an SE or SES and the sporty ST version is only available as a sedan. Side-impact air bags are optional on all models, while anti-lock brakes are optional on S, SE, and SES models. Other top options include heated seats and ambient LED interior lighting.
