Similar to the Euro-spec CLA250 Sport introduced in Frankfurt (if not identical save for the mirror caps), the US-spec CLA 250 Sport Package Plus includes a special set of 18-inch alloys, upgraded exhaust and retuned suspension. It also gets red accents on the bumpers and an interior with more robustly bolstered buckets and red stitching. All of this comes on top of the aero kit, chrome grille and upgraded brakes on the existing Sport Package.
Those are the only mechanical changes, so don't go looking for any more juice out of the 2.0-liter turbo four than the 208 horsepower and 258 pound-feet of torque that come standard, channeled as they are either to the front wheels or all four through a seven-speed dual-clutch transmission. Pricing for the Sport Package Plus hasn't been announced, but the existing Sport Package was already going for $2,200, so expect to shell out even more than that for the new kit.
