2011 Toyota Sienna III Dimensions, Size & Specs

The curb weight of the Toyota Sienna III ranges from 1939 kg (4277 lbs) to 2080 kg (4587 lbs). Variations in weight are influenced by trim levels, drivetrain options (such as front-wheel drive versus all-wheel drive), and additional equipment packages. This weight is typical for a minivan of this size, balancing robust construction with the need for efficiency and performance. Heavier trims may offer additional safety features and luxury appointments, contributing to the upper end of the weight spectrum.

The Toyota Sienna III features a ride height or ground clearance ranging from 157 mm (6.18 inches) to 170 mm (6.69 inches). The exact clearance can vary with different trim levels and wheel sizes. This moderate ground clearance strikes a balance between passenger comfort, ease of entry/exit, and the ability to handle urban road irregularities. While the Sienna is not designed for off-road usage, this clearance is adequate for typical suburban and highway driving conditions, providing good stability and ride quality.

The Toyota Sienna III is well-regarded for its expansive cargo capacity, offering 993 liters (35.1 cubic feet) of luggage space behind the rear seats under normal passenger configurations. When rear seats are folded down, this capacity dramatically expands to approximately 3810 liters (134.4 cubic feet). This vast space makes the Sienna ideal for transporting both people and large cargo with versatility. Whether used for family trips or bulky items, the folding seats provide flexible utility that is a hallmark of minivan design.

The Toyota Sienna III offers rim options in 17-inch, 18-inch, and 19-inch sizes, paired with respective tires sized 235/60 R17, 235/55 R18, and 235/50 R19. Larger rims generally contribute to a slightly higher overall vehicle height due to changes in tire sidewall height and profile. The tire size variation also affects ride comfort and handling; for example, 19-inch rims with lower-profile tires tend to offer crisper handling and sportier aesthetics, while 17-inch rims with taller tires prioritize comfort and cushioning over rough surfaces. These options allow buyers to select configurations that best suit their driving preferences.

Standard residential garages typically have an interior width of about 2.4 to 2.7 meters (8 to 9 feet) and a height clearance around 2.1 to 2.4 meters (7 to 8 feet). The Toyota Sienna III’s width of 1984 mm (78.1 inches or approximately 6.5 feet) and height ranging from 1755 to 1811 mm (69.1 to 71.3 inches or approximately 5.75 to 6 feet) means it fits comfortably within the width and height of a standard garage with some clearance space around. However, the minivan's length of 5085 mm (200.2 inches or about 16.6 feet) might require a garage with sufficient depth, as some garages designed for typical sedans may feel tight lengthwise. Overall, most standard home garages can accommodate the Sienna, though very small or narrow garages might be a tight fit.

Compared to the Sienna II (produced roughly from 2003 to 2009), the Sienna III introduced a slight increase in length and width, enhancing interior space and cargo volume. The Sienna II typically measured around 5000 mm (197 inches) in length and had a width slightly less than 1980 mm (78 inches). The third generation’s 5085 mm length and 1984 mm width made for a roomier cabin and improved passenger comfort. Height variations were fairly consistent, though certain trims of the Sienna III presented a taller profile for increased headroom. Overall, the third generation increased usability and space efficiency while retaining the family-friendly dimensions of its predecessor.

The Toyota Sienna III’s dimensions position it competitively among minivans like the Honda Odyssey, Chrysler Town & Country, and Kia Sedona from the same era. At 5085 mm (200.2 inches) in length, it is comparable in size but slightly longer than the Honda Odyssey III generation, which is approximately 5095 mm (200.6 inches). Its width (1984 mm or 78.1 inches) is on par or slightly wider than competitors, contributing to spacious interiors. Cargo capacity with rear seats folded (3810 liters or 134.4 cubic feet) is generous and comparable to or exceeding many rivals, emphasizing Toyota's focus on versatility. Ground clearance and curb weight align with segment norms, ensuring the Sienna remains practical and competitive family transport.

The Toyota Sienna III typically seats seven or eight passengers depending on configuration, with either second-row captain’s chairs or a bench seat. The interior space is designed to maximize comfort, with ample headroom and legroom afforded by the minivan’s generous dimensions. The width of nearly 2 meters ensures enough shoulder space for three front passengers or in the second row, contributing to a spacious cabin feel. The flexible seating arrangements and ease of access via sliding doors make it ideal for families or group transport. Interior amenities often include configurable storage and advanced climate controls to enhance passenger comfort.

The third-generation Toyota Sienna debuted significant enhancements over the second generation, notably in size, design, and technology. It introduced a more aerodynamic and modern exterior, improving fuel efficiency and aesthetics. Interior upgrades included increased cargo capacity and improved seating comfort with optional captain's chairs, as well as better sound insulation for quieter rides. Safety features were upgraded with available advanced systems like Vehicle Stability Control and improved airbag systems. Additionally, the introduction of all-wheel drive options boosted versatility, making the Sienna III more adaptable for varied driving conditions compared to the predecessor.
