The 840i xDrive is essentially the same model as the entry-level spec, save for the all-wheel-drive system. It shares standard features that include keyless entry and push-button start, heated 14-way power-adjustable front seats with four-way lumbar support, and wireless charging. The extra weight and mechanical load from the AWD system mean that it’s not as economical, but the added grip allows it to get to 60 mph almost half a second faster than the base model.
