The Chevrolet Trailblazer's twin, the GMC Envoy could also enjoy increased sales due to lesser large SUV sales, penalised by high oil prices. From now on, the Envoy is available in a five passenger version only, and as Envoy and Envoy Denali variants. The 285 horsepower 4.2-litre six in-line cylinder engine is standard, while the 300 horsepower 5.3 litre V8 engine is reserved for the Denali model. With a four-speed automatic transmission, they are offered with 4x4 or all-wheel drives.
