The 2013 BMW X6 model cannot be modified to the 2017 exterior style, as the body appearance has undergone significant changes, requiring custom body kits. 2013 BMW X6 dimensions: The body dimensions of the 2013 BMW X6 are 4880mm in length, 1983mm in width, and 1709mm in height. 2013 BMW X6 exterior: BMW defined the 2013 X6 as an SAC, which stands for Sport Activity Coupe. Compared to the X5, which is positioned more towards road performance, the X6 has evolved more thoroughly in terms of road capabilities, blending the sportiness of a coupe with the versatility of an SUV in its exterior design and dynamic handling.

I've seen many cases of facelifting 2013 X6 models to 2017 specs, which mainly involves exterior modifications. For the front end, you'll need to replace the new-style kidney grille, bumper, and headlight assembly. Just swapping the headlights requires rewiring since the connectors differ between old halogen and new LED units. Rear modifications entail changing the taillights and rear bumper, which also involves adjusting the reverse radar mounting positions. The wheel arch shapes differ when viewed from the side, and forced modifications would leave obvious gaps. The interior is basically impossible to modify because the 2017 version features a full digital instrument cluster with completely different dashboard architecture. Finally, you'll need to re-register the vehicle to match the modified appearance with the license photo, otherwise annual inspections will definitely flag it. This is truly a massive project - the labor costs alone could nearly match the price of used parts.

Last time I helped a friend upgrade this old model, the most troublesome part was the electrical system compatibility. The modifications involved included the bumper brackets, headlight module, fog light wiring harness, and even the windshield washer reservoir position had to be adjusted. The biggest issue after the upgrade was the impact on the active safety system, such as the automatic headlight leveling possibly throwing fault codes. My suggestion is to go all-in with OEM parts if you're modifying, as aftermarket parts have poor fitment and are prone to rattling. Additionally, the 2017 model with chassis code F16 and the 2013 E71 have different suspension tower positions. If you want to modify the suspension setup, you'd even need to cut and re-weld the suspension towers. Modifications to this extent will definitely fail the annual inspection, it's just creating unnecessary trouble for yourself.

In fact, this kind of cross-generation modification mainly falls into three scenarios: The first involves only changing the front and rear bumpers and light clusters, making the appearance similar but the details unable to withstand scrutiny; the second includes replacing even the fenders, requiring cutting and welding the original factory weld points; the third is transplanting the entire set of body panels, which is equivalent to reassembling half of the car. The first type can be done for twenty to thirty thousand yuan, while the latter two can easily cost up to a hundred thousand. Additionally, the issue of second-hand residual value must be considered. Cars with such extensive modifications will be thirty to forty thousand yuan cheaper than factory-original cars of the same year when sold later. Insurance companies also find it troublesome to assess damages, and the increase in insurance premiums can outpace the cost of modifications.
