The X6 is available in three primary trim lines. The X6 sDrive35i leads off with an MSRP of $60,600; the step up to the X6 xDrive35i adds an extra $2,300, The X6 xDrive50i starts at $75,300. (The monstrously powerful and much more expensive X6 M is covered in a separate article.)
Power for the sDrive35i and xDrive35i comes from a 3-liter inline-six boosted by two turbochargers; the xDrive50i receives its substantial motivation from a 4.4-liter V8, which also wears a pair of turbos.The sDrive35i forgoes the all-wheel drive system of its xDrive sisters in favor of rear-wheel drive.
Underneath its teardrop roofline the X6 shares its platform with BMW's X5, which provides significant benefits (excellent handling) with some limits (no real off-road capability). After choosing your basic mechanics you then immerse yourself in BMW's complex -- and pricey -- option structure, starting with the choice of xLine (essentially base) or M Sport (bigger wheels, aero package and other styling tweaks) lines and proceeding through different interior treatments and tech packages.
- Plenty of driver assistance electronics are available, including night vision and radar cruise control with a full-stop capability.
- The M Sport trim line is an effective visual bridge between the normal X6s and the X6 M, upgrading the looks without breaking the bank.
Feel free to outfit the X6 with enough sensors and computer assists to manage a starship, but know that per upscale German tradition the added cost will be astronomical as well. A bit of restraint serves a buyer well here.
