A new BMW X5 is coming within the next year or so and it will be using the same underpinnings as the 7-Series.
Autocar reports the next-generation X5 will use BMW's new CLAR - Cluster Architecture - modular platform. This platform is comprised of high-strength steel, aluminium, and carbon fiber. Not only does this cut weight, but increases structural rigidity. CLAR is predominantly built for rear-wheel drive applications, but it can take on an all-wheel drive system.
This platform will go on to underpin a number of other BMW vehicles such as the next-generation 3 and 6-Series.
Engine choices for the next X5 are reported to be a 3.0L straight-six, a new twin-turbocharged V8, and a 6.0L V12 for the high-end models. There is also the possibility of a hybrid model.
One interesting item is that the new X5 will not share much with the recently announced X7 crossover. The X7 will the flagship of BMW's crossover lineup and take on the likes of the Mercedes-Benz GLS-Class and Range Rover. As BMW head of sales and marketing Ian Robertson told Autocar, the X7 will pick various engines across the lineup.
