Offering comfortable seating for up to eight, the strong and durable Tahoe carries over virtually unchanged for the 2020 model year. It relies on 355- and 420-horsepower V8 engines with a towing capacity of up to 8,500 pounds. However, General Motors is completely redesigning all of its full-size SUVs for 2021, including the Tahoe, so customers wishing for the latest in styling and technology, not to mention improved fuel economy, need to wait a bit longer.
