In addition to the short-wheelbase 740i, BMW offers the long-wheelbase 740Li and 740Li xDrive, which features all-wheel-drive. The major advantage in the Li models is rear legroom, which gains 5.5 inches.
BMW has treated the large sedan to many eco-friendly updates for 2013. Along with a more efficient engine, new features like automatic engine stop/start and an EcoPro drive setting all contribute to conserving fuel.
