Why Settle for a 2025 Toyota Grand Highlander When You Can Get a Sienna?

The Minivan Might Be King After All

After spending a week behind the wheel of the 2025 Toyota Grand Highlander, I began to understand why minivans continue to dominate in family transportation. Even though this is its second model year, the Grand Highlander offers impressive passenger space, visibility, and an efficient hybrid powertrain that makes it a compelling choice for many. It’s also reasonably priced, especially when considering the Hybrid Max version, which is only slightly more expensive than the top-of-the-line Sienna.

But this experience made me wonder: if people are looking for spacious seating, cargo capacity, and a third row, why not just go with the well-established Sienna? No three-row SUV, even those with high price tags like the Cadillac Escalade or Lincoln Navigator, can match the practicality of a minivan. As someone who used to dislike minivans, I now find myself questioning why anyone would choose an SUV over a minivan, even after comparing both models.

Passenger and Cargo Space: The Sienna Wins

When comparing the Sienna and the Grand Highlander, the differences in size and space become immediately apparent. The Grand Highlander measures 201.4 inches long, 78.3 inches wide, and 72.1 inches tall, while the Sienna is slightly longer at 203.7 inches, but significantly shorter at 68.5 inches. The wheelbase of the Sienna is also longer at 120.5 inches compared to the Grand Highlander’s 116 inches.

In terms of passenger and cargo volume, the Sienna clearly outperforms the Grand Highlander. The Grand Highlander offers 153.3 cubic feet of passenger space, while the Sienna provides 162.5 cubic feet. Behind the third row, the Sienna has 33.5 cubic feet of space compared to the Grand Highlander’s 20.6 cubic feet. When the third row is folded down, the Sienna’s cargo capacity reaches 75.2 cubic feet, versus the Grand Highlander’s 57.9 cubic feet.

The third row in the Sienna is also more comfortable, with over 38.7 inches of legroom compared to the Grand Highlander’s 33.5 inches. For long trips or car seat installations, the Sienna feels more accommodating.

Configurations and Features: The Sienna Offers More Flexibility

The Sienna comes with captain’s chairs in the second row, and it can be configured with a middle jumper seat that can be removed or converted into an armrest. This flexibility allows for a 7- or 8-seater configuration, depending on needs. In contrast, the Grand Highlander offers captain’s chairs as an option but lacks the same level of adaptability.

Additionally, the Sienna offers features such as rear-seat entertainment systems, sliding doors, and wider entry points. These make it easier to load kids and gear in tight spaces. The Sienna also includes built-in vacuum systems and beverage coolers in higher trims, which are absent in the Grand Highlander.

Price Range: Both Models Offer Wide Options

The base model of the Sienna starts at $39,485, though it is front-wheel drive. The most expensive Sienna, the Platinum AWD hybrid, can reach up to $59,080 with additional options. The Grand Highlander, on the other hand, comes in 10 different configurations, starting at $41,360 for the gas-only model and going up to $59,275 for the Hybrid Max Platinum.

While the Grand Highlander is technically more expensive, it offers more power through its Hybrid Max system, making it a better choice for those needing towing capabilities.

Power and Towing: The Grand Highlander Excels

For families that need to tow heavy loads, the Grand Highlander stands out. It can be equipped with a 2.4-liter turbocharged engine that delivers 362 horsepower, compared to the Sienna’s 245 horsepower. This gives the Grand Highlander a higher towing capacity of 5,000 pounds, compared to the Sienna’s 3,500 pounds.

If you require more than 5,000 pounds of towing, alternatives like the Ram 1500 or Ford F-350 diesel may be necessary.

Final Thoughts

After driving both vehicles, I found them both to be excellent family cars. However, if I had to choose, I would lean toward the Sienna for its versatility, ease of use, and unmatched space. The Grand Highlander is a solid choice for those who prefer an SUV but still want enough room for their family. It’s ideal for families with older children or grandparents who need extra space for visits.

Ultimately, the Sienna remains the best choice for families with younger kids due to its ease of use and superior cargo capacity. The Grand Highlander, while not as space-efficient, offers a more dynamic driving experience and is perfect for those who don’t want to compromise on style or performance.
