The F-150 delivers all the manly attributes of toughness, strength, and imposing size, although it is largely sold here as a fashion statement for tiny men. Redesigned for 2009 and updated in 2011, the fully-loaded F-150 crew-cab is sold here as more of a lifestyle vehicle, offering interior design and comfort that would rival some luxury cars. Properly equipped, it can haul more than a tonne in its bed. The F-150 is comfortable as well, with a quiet and refined ride. It comes with dual front and side airbags, cloth or leatherette seats, CD/MP3 stereo, and air conditioning as standard. Other available features include an optional 4.2-inch LCD screen, hill descent control, electronic locking differential settings and stability control. A host of power and luxury options are available too. For all these reasons, the F-150 has been America's best-selling full-size pickup for nearly 30 consecutive years. It is the most most profitable vehicle Ford makes. It is available in various trim levels, variations, and specialty models, including quad cab, single cab and dual cab model, with various bed sizes. New engines redefined the line-up for 2011, with a new 3.7-litre V6 and a new 5.0-litre V8, both from the Mustang, and fitted with automatic transmissions and a choice of rear-wheel-drive or four-wheel-drive. The top version is called the Platinum, while a special Harley-Davidson trim is also available. The F-150 SVT Raptor also became available on special-order, in 6.2-litre V8 form, and identifiable by its unique body mods and aggressive offroad suspension.
