The LZ9 V6 3.9 L engine received a power boost in 2006 to deliver 240 hp and produce 240 lb-ft of torque. New features for the 2007 model included both a flex-fuel version of the 3.9 L V6 alongside an all-wheel-drive system as optional options. The Buick Terraza maintains a stable driving character from its dimensions of wheelbase 121.1 inches and total length 205.0 inches alongside curb weight between 4,440 to 4,689 pounds.
