Sharing platforms, powertrains, and components with the Buick Terraza, Chevrolet Uplander, and the Saturn Relay, the Montana SV6 debuted last year as a "crossover sport van" for those buyers who might prefer a sport-utility vehicle, but require a minivan for family transport. While it offers more aggressive exterior styling and rides slightly higher than the typical people mover, it's outdistanced by better minivans on the market. Its 3.5-liter V-6 engine generates a just-adequate 200-horsepower and comes mated to a four-speed automatic transmission. A new 3.9-liter V-6 will be introduced later in the model year for a welcome power boost. Both front- and all-wheel-drive models are available. Four-wheel disc brakes are standard, with anti-lock brakes and traction control optional. The Montana SV-6 incorporates foldable second- and third-row seats, with a 50/50-split rear seat which folds flat into the floor. A DVD entertainment system comes standard. For 2006, head curtain airbags are newly offered for first- and second-row outboard passengers.
