brands have increasingly introduced SUV or crossover models in the 2010s. For example: Rolls-Royce Cullinan, Bentley Bentayga, Aston Martin DBX, Maserati Levante, and Lamborghini Urus. Ferrari has announced that they will release an SUV model Ferrari Purosangue in 2022. In 2019 SUVs made up 47.4% of U.S. sales compared to only 22.1% for sedans. Motorsport SUVs have competed in various off-road racing competitions, such as the Dakar Rally, Baja 1000, FIA Cross-Country Rally World Cup, King of the Hammers, and Australasian Safari. SUVs have also competed in the Trophee Andros ice-racing series. Nicknames Several derogatory or pejorative terms for SUVs are based on the combination of an affluent suburb name and "tractor", particularly for expensive vehicles from luxury brands. Examples include "Toorak Tractor" (Melbourne, Australia), "Chelsea Tractor" (London, England) and "Remuera Tractor" (Auckland, New Zealand). These terms relate to the theory that four-wheel drive capabilities are not required by affluent SUV owners, and that the SUV is purchased as a status symbol rather than for practical reasons. In Norway, the term ('Stock Exchange Tractor') serves a similar purpose. In the Netherlands, SUVs are sometimes called "P.C. Hooft-tractors" after the exclusive P.C. Hooftstraat Amsterdam shopping street. Commercial SUVs A commercial SUV is an SUV or crossover, that is used for commercial purposes. The category is very similar to panel trucks since the Chevrolet Suburban (an SUV) had panel truck versions, which were used for commercial purposes. The first SUV-like vehicle that had commercial versions was the Chevrolet Suburban panel truck. Panel trucks by American manufacturers were built until the late 1970s. While panel trucks manufactured by European manufacturers were rare, commercial versions of off-road vehicles were very common, Land Rover manufactured commercial versions of the Land Rover and the Defender. Commercial SUVs are factory-built and most of them are not independent conversions, which means they can be bought from dealerships and showrooms. Examples of SUVs used as commercial vehicles in Europe include: Citroen C5 Aircross Commercial SUV, the Land Rover Discovery, the Dacia Duster Flika, and the Mitsubishi Pajero.
