The redesigned Sienna minivan is arguably one of the most sensible vehicles to ever hit the planet. It can seat up to eight passengers, sips precious little fuel, rides comfortably, is available with all-wheel-drive, and has an extremely functional interior. The driving experience is unlikely to raise anyone’s pulse, but in terms of sheer logic, few vehicles do it better than the Sienna.
Starting with the 2021 model year, the Sienna comes exclusively as a hybrid, with a combined 245 horsepower between the electric drive and the 2.5-liter four-cylinder engine. Front-wheel drive is standard, with all-wheel drive optional. Its fuel economy easily trumps all other minivans, at 36 mpg overall in our testing, and the Sienna can glide along on electric power at very low speeds. However, when more power is needed the gas engine gets noisy. This lack of powertrain refinement is a letdown compared to most other minivans (including the previous Sienna), which utilize V6 engines and have a more effortless power delivery.
In most cases, automotive warranties are based on the vehicle identification number (VIN), and the warranty will be valid regardless of ownership. The dealership can tell you exactly how much warranty is left.
