BMW has indeed confirmed a sportier, high-performance X3 in the form of the X3M. Our spies have snapped the sports crossover doing laps around the Nurburgring several weeks ago. However, it's not just BMW that will be building a hotter X3.
Alpina, a long time tuning house specializing in BMWs is now testing the next-generation XD3. Unlike the X3M, the XD3 will be powered by a turbodiesel engine, uprated by the semi-official tuner. Alpina has been producing high-powered diesels since the 90's and the XD3 will continue that tradition. Besides this crossover, there are also sportier diesels from the brand, namely the D3 (based on the 3 Series) and D4 (based on the 4 Series).
While official engine specs have yet to be released, expect it to dole out more power than the current model. As it stands, this year's XD3 produces 350 PS and 700 Nm of torque from its 3.0-liter TwinPower Turbo diesel straight-six. The new XD3 will still use the said inline-six turbodiesel and power is likely to be close to the 400 PS mark, and well over 700 Nm of torque. xDrive all-wheel drive will be standard.
As far as appearance goes, the 2018 XD3 will get its own unique front and rear bumpers with the fronts likely coming with the signature Alpina marking on the apron. The rims will be different too and will not be seen on any BMW options catalogue. These new 20-inch wheels are similar in design with the Alpina B5 (based on the 5 Series). Also, expect a host of Alpina touches to the interior with different trimmings, panels and badges.
