By all indications in these spy shots, the Lambda-based production Buick Enclave will be much like the 2006 Detroit show car, with its curvy sheetmetal and premium interior. It launches with a 270-horsepower, 3.6-liter 24-valve V-6, but it's also designed for GM's dual-mode hybrid system, and the Lucerne's 4.6-liter 32-valve V-8 also is possible for the 2009 model year.
