The Toyota Sienna gets a more powerful and efficient drivetrain starting in 2017. The new engine shares its predecessor's 3.5-liter displacement, but produces 30 additional horsepower, for a total of 300. Meanwhile, the transmission gains two new gears, which aim to improve efficiency and acceleration. Despite the increased speed, Toyota expects the Sienna to get better fuel economy, both around town and on the highway, thanks to the new transmission.
