BMW was an originator of the coupe-styled SUV, and now the X6 Sports Activity Coupe is ready to debut a thrird-generation model for 2020.  The new body is longer, wider and lower for a more stable stance and aggressive character. The 5-passemger interior is swathed in luxury touches and inlcudes the latest technology and driver-assistance features BMW has to offer. The new X6 also serves as the premiere for an optional illuminated BMW kidney grille that, as part of the daytime running light feature, can remain on while the vehicle is in motion.   Set to begin production in August at BMW's Spartanburg, SC plant, the all-new X6 will enter the market this November with 335 hp sDrive40i and xDrive40i and 523 hp M50i versions and a starting base price of $64,300.
