Owners of the next, aesthetically relaxed 7-series might not have to spend half their time defending their cars' looks, but they'll still be kept busy deciphering the big car's electronic doodads. The future BMW supersedan will include a head-up display, four-wheel adjustable air springs, an eye-movement monitor, a lane-departure warning system, and possibly a fission reactor. A hybrid version will follow after the standard model, which arrives in 2008.
