Like the Chevy Venture and Oldsmobile Silhouette, the Montana is powered by a 185-horsepower, 3.4-liter V6 engine attached to a four-speed automatic transmission that drives the front wheels. This type of layout is common to all the best-selling minivans. The engine sits in the usual sideways position, which allows maximum use of interior space. The suspension is independent up front, with a twist-beam axle in the rear; again like the Olds and Chevy minivans. The twist-beam axle is simpler than an independent setup, but nearly as light, and contributes much-needed rear roll stiffness in a front-heavy vehicle.
