The images reveal a number of visual changes from the current model, including a bulkier centre stack and an infotainment display that rises out of the dash rather than being integrated.
BMW is likely to address criticisms of the original X1's cabin quality, while a switch from a rear-wheel-drive 3 Series underpinnings to the new front-wheel-drive UKL1 platform that should liberate more interior space.
The platform, shared with the Mini, 2 Series Active Tourer and third-generation 1 Series, will also be available with all-wheel drive.
Our spies grabbed some fresh images of the new BMW X1 as well, which despite the camouflage points to a better proportioned SUV - especially at the front end where the bonnet and overhangs are notably shorter.
The side sheetmetal also looks deeper, while the higher rear section suggests the new X1 should offer more boot space.
A sportier-looking X2 variant along the same lines of X3/X4 and X5/X6 is expected to be spun off the next X1, while BMW is understood to be considering an M version to rival the Audi RSQ3 and Mercedes-Benz GLA45 AMG.
