As advanced as the transmission controls are, I found it slightly annoying not to be able to place my hand on a gear lever and

perform a manual downshift when approaching a red light or moderating downhill speed. If BMW really wants to make the iDrive mouse useful, they should incorporate a simple maneuver into the device that would enable downshifting. The only way downshifting can be undertaken at present is by cycling through the steering wheel button that activates the Steptronic mode, then switching to the Steptronic button to perform a downshift. Of course once the downshift has been achieved, re-cycling through the first button is necessary to revert from Steptronic to the basic automatic mode. So in my view, BMW hasn't nailed the driver-controlled functionality of the 745's gearbox.
What the engineers have nailed, however, is the 745Li's precise handling characteristics. My test unit was equipped with an optional set of massive 20-inch rims wrapped in low profile, Michelin Pilots. When combined with BMW's Dynamic Drive (Active Roll Stabilization) technology, the wheel/suspension setup delivers the unimaginable: big car ride comfort combined with performance car handling. When trudging about town, the 745Li insulates its occupants from the harshness of broken roads, noisy trucks and foul weather. Road noise is mostly extinguished and wind rush at highway speeds is minimal. Those experiencing these pleasures will undoubtedly also enjoy the firm, but docile ride of the big flagship. But hammer the boulevard cruiser into a turn and a Jeckyl and Hyde effect takes over.

Suddenly serenity gives way to tenacity. The 745Li swoops around bends and switchbacks without leaning or unduly punishing the Michelins, thanks in part to its front and rear active anti-roll stabilizer bars; active because actuators integrated within the roll bars apply opposing forces on the front and rear axles during cornering. Steering turn-in is crisp, especially for a large car carrying two-plus tons of mass. Although my road testing didn't include track-like driving demands it did deliver an enthusiastic run through the mountains, and in my experience the handling thresholds of the 745Li are well beyond levels needed to ensure driver confidence or competence for that matter. This car's handling athleticism rewards like few other cars of similar girth.
