North America[edit] There is no one definition for an SUV.[4] Most government regulations simply have categories for "off-highway vehicles," which in turn are lumped in with pickup trucks and minivans as "light trucks."[4] The auto industry has not settled on one definition.[4] Nevertheless, four-wheel-drive SUVs are considered light trucks in North America (and two-wheel-drive SUVs up to the 2011 model year[5]) where they were regulated less strictly than passenger cars under two laws in the United States, the Energy Policy and Conservation Act for fuel economy, and the Clean Air Act for emissions.[6] Starting in 2004, the United States Environmental Protection Agency (EPA) began to hold sport utility vehicles to the same tailpipe emissions standards as cars.[7] Many people question "how can an SUV be called a truck?"[8] Although the original definition of the "light truck" classification included pickups and delivery vans, usually SUVs and minivans are included in this category because these vehicles are designed to "permit greater cargo-carying capacity than passenger carrying volume.[8] Manufacturing, emissions, and safety regulations in the U.S. classify "an SUV is a truck"; however, for local licensing and traffic enforcement, "an SUV may be a truck or a car" because the classification of these vehicles varies from state to state.[9] For industry production statistics, SUVs are counted in the light truck product segment.[10] http://en.wikipedia.org/wiki/Sport_utility_vehicle The BMW 5-Series is an executive/mid-size luxury car manufactured by German automaker BMW since 1972. The car, now in its sixth generation, is sold in sedan and touring body styles. It is BMW's second best-selling model after the 3-Series and in 2010 produced about 50% of the BMW's profits.[1] On January 29, 2008, the 5 millionth 5-Series was manufactured, a 530d Saloon in Carbon Black Metallic.[2] The F10/F11/F07 is the sixth-generation 5-Series, produced from 2010–present. The platform is based on the F01 7 Series; improvements include a front dual ball joint short-long arm suspension (replacing the MacPherson strut suspensions BMW previously used), and a rear multilink suspension.[33] The interior marks the return of the centre console being clearly angled towards the driver, another marked change from its immediate predecessor which was noted for its non traditional BMW design.[34][35] However, opinion is divided, as a reviewer described the F10 as too bland and conservative, compared to the E60 predecessor, as well as having too much of a resemblance to the E90 3-Series.[36] The F10 M5 uses the S63 twin-turbocharged V8 engine and is the first M3 or M5 to use forced induction. A long-wheelbase version is sold in China.[37] Mexican-built armored BMW 5 vehicles are also built on the wheelbase from the Chinese long-wheelbase model. This armoured model is known as the BMW 5 Security and only is available in long-wheelbase form with the 4.4L V8 engine. 5-Series Gran Turismo (F07)[edit] BMW 535i Gran Turismo Main article: BMW 5 Series Gran Turismo In 2009, BMW released the 5-Series Gran Turismo (F07), a five-door fastback of similar body style to the Porsche Panamera. The GT is taller than other fastback competitors.[38] The F07 (designed by Christopher Weil) shares the same F01 7 Series-derived platform, powertrain, and mechanical package with the F10. However, the F07's fascia has different headlights and bumper, with a larger split-kidney grille similar to that of the F01 7 Series. The F07 is also taller, resulting in a higher center of gravity and its greater length allows for more rear legroom.[citation needed] The F07 also features frameless doors and a double-pane liftgate truck.[39] The F07 is the first BMW to receive the new ZF eight-speed automatic transmission, along with a new Brake Energy Regeneration system.[40] http://en.wikipedia.org/wiki/BMW_5_Series
