With the 2009 redesign, BMW's flagship lost its crispness. Handling lacks agility and as a result, the 750Li we tested doesn't shine at its limits. The ride is steady and supple but not that cushy. The turbo V8 is smooth, refined, and punchy. Gas and diesel six-cylinders are also available, along with a mighty V12. Many of the secondary controls are complex and frustrating to use. On the plus side, the roomy cabin is super-quiet and impeccably finished. Further, seat comfort is tops. The 2011 models brought an optional driver assistance package including lane-departure warning and blind spot detection systems. For 2013, the 7 Series got an eight-speed automatic transmission and all-wheel drive was made available with the six-cylinder engine. For 2015, models were offered with a 255-hp diesel engine that came standard with all-wheel drive.
