The major difference between the two engines is that one has a cast-iron block and the other an aluminum block; each delivers 320 horsepower, is matched with a 6-speed automatic transmission, and provides all the power and performance most customers will need. With its rigid chassis, the Tahoe feels taut for its size, steering is precise and responsive, and the brakes are capable and smooth. Based on a platform similar to the Suburban and Silverado models, the Tahoe makes a stable rig for pulling trailers
