If consumers want crossovers and SUVs (as all sales charts suggest), why should premium carmakers like BMW disagree? The brand with the roundel logo is keen to capitalize on the growth of this segment, something that is evident from the sales of its X-series models, which now account for one in every four new cars it delivers worldwide. BMW has split its SUVs into two basic categories, the more mainstream “Sports Activity Vehicles” (SAV), which include the X1, X3 and X5, and the “Sports Activity Coupé” (SAC), which up until now, was represented only by the larger X6. Today, the Bavarian carmaker previewed its second SAC model in the form of the X4 Concept, a couple of weeks ahead of its world premiere at the Shanghai Auto Show in China on April 21. The styling of the X4 is the work of BMW head designer Karim Habib and his team, who lifted the template from the X6 and applied the same recipe on the more compact platform of the X3, with the front and rear ends of the crossover drawing inspiration from the latest 3-Series F30 and the upcoming 4-Series Coupe. Like many other concept models from BMW, this one too is well over 90 percent ready for production, as only minor details will change, such as the door mirrors, the trims of the bumpers, and the use of smaller wheels (the study rides on 21-inch rims). With a body length of 4,648mm (183-inches), a width of 1,915mm (75.4 inches) and a height of 1,622mm (63.9 inches), is very close in dimensions to the X3, with which it shares the same wheelbase length of 2,810mm (110.6-inches). BMW doesn’t show the interior nor does it mention anything about the X4’s powertrain lineup, but it’s almost guaranteed that both will be sourced from the X3 (the cabin likely with some subtle trim differences). That said, if you take a look at the more powerful diesel and gasoline engine options available for the X3 in your region, then you will have a very good idea of what the X4 will be offered with next year. These will include the 240-horsepower 2.0-liter turbocharged inline four for the X4 28i, and the 300-horsepower 3.0-liter turbocharged straight-six for the X4 35i in North America. BMW has confirmed that the X4 will be built alongside the X3, X5 and X6 at its Spartanburg plant in the USA.
