Looking for a reliable SUV for your family? Check out our in-depth comparison of the Toyota Grand Highlander and Sienna, covering seating capacity, engine performance, safety features, and more to help you make the best choice.

Seating Capacity and Comfort

When it comes to choosing a vehicle, seating capacity and comfort are often top priorities for families and road trippers alike. But how do the Grand Highlander and Sienna measure up in these crucial areas?

Number of Seats and Configurations

The Grand Highlander offers plenty of space for passengers, with a total seating capacity of eight people across three rows. The second row features captain’s chairs that can slide and recline, while the third row provides ample space for kids or smaller adults. Meanwhile, the Sienna offers a slightly different configuration, with seating for up to eight passengers across three rows, but with a bench seat in the second row instead of captain’s chairs. While both vehicles offer similar passenger capacity, the Grand Highlander’s captain’s chairs in the second row provide more flexibility and comfort for middle-row passengers.

Legroom and Headroom Comparison

When it comes to legroom and headroom, both vehicles provide ample space for passengers to stretch out and get comfortable. The Grand Highlander offers 44.4 inches of legroom in the second row and 35.6 inches in the third row, while the Sienna provides 39.1 inches in the second row and 30.2 inches in the third row. In terms of headroom, the Grand Highlander offers 40.1 inches in the second row and 37.8 inches in the third row, while the Sienna provides 39.7 inches in the second row and 38.3 inches in the third row. While both vehicles offer similar headroom measurements, the Grand Highlander’s slightly more generous legroom in the second and third rows gives it a slight edge in this department.

Premium Materials and Features

But it’s not just about the number of seats and space – it’s also about the quality of the materials and features that make up the interior. The Grand Highlander boasts premium materials and features like available heated and ventilated front seats, a heated steering wheel, and a panoramic moonroof that lets in plenty of natural light. The Sienna, on the other hand, offers its own set of premium features, including available heated and ventilated front seats, a moonroof, and a premium Entune 3.0 infotainment system with a large touchscreen display. Both vehicles offer a range of premium materials and features, but the Grand Highlander’s slightly more upscale interior design gives it a slight edge in this department.


Engine Performance and Fuel Economy

When it comes to getting from point A to point B, the Grand Highlander and Sienna are both designed to deliver a smooth and efficient ride. But how do they compare when it comes to engine performance and fuel economy? Let’s dive in and explore the details.

Horsepower and Torque Comparison

When it comes to raw power, the Grand Highlander and Sienna are closely matched. The Grand Highlander’s 3.5-liter V6 engine produces 295 horsepower and 263 lb-ft of torque, while the Sienna’s 3.5-liter V6 engine churns out 296 horsepower and 263 lb-ft of torque. That’s right, folks – these two minivans are practically neck and neck when it comes to horsepower and torque. So, what does this mean for you? Well, both vehicles have more than enough oomph to tackle steep hills, merge onto highways, and haul heavy loads with ease.

Fuel Efficiency in City and Highway

Of course, power is only half the story – fuel efficiency is just as important, especially for families who do a lot of driving. According to the EPA, the Grand Highlander gets an estimated 24 mpg combined (21 city, 29 highway), while the Sienna gets an estimated 27 mpg combined (23 city, 30 highway). That’s a notable difference, especially for city dwellers who do a lot of stop-and-go driving. However, it’s worth noting that both vehicles are still quite fuel-efficient, considering their size and power output.

Transmission Options and Performance

When it comes to transmission options, both the Grand Highlander and Sienna offer a smooth-shifting 8-speed automatic transmission. This means you can expect seamless acceleration and responsive shifting, whether you’re cruising down the highway or navigating heavy traffic. Additionally, both vehicles offer a range of drive modes, including sport, eco, and normal, which allow you to customize your driving experience to suit your mood and terrain. So, whether you’re hauling kids to soccer practice or tackling a road trip adventure, these transmissions have got you covered.


Safety Features and Ratings

When it comes to safety, both the Grand Highlander and Sienna are designed to provide peace of mind for drivers and passengers. But how do they compare?

The Grand Highlander features a total of seven airbags, including dual front, front side, rear side, and side curtain airbags.

NHTSA and IIHS Ratings

So, what do the safety ratings from NHTSA and IIHS reveal about the Grand Highlander and Sienna? As mentioned earlier, the Grand Highlander earned a perfect 5-star overall safety rating from NHTSA, while the Sienna scored 4.5 stars out of 5. In IIHS testing, both vehicles received Top Safety Pick+ designations, the highest rating awarded. However, it’s worth noting that the Sienna’s rating was conditional, pending the availability of certain advanced safety features.

Infotainment and Technology

When it comes to staying connected and entertained on the go, the Grand Highlander and Sienna are equipped with cutting-edge infotainment systems that will keep you and your passengers engaged. But which one takes the crown in terms of display screen size, smartphone integration, and premium audio systems?

The Grand Highlander boasts an impressive available 12.3-inch touchscreen display, providing crystal-clear graphics and intuitive navigation. In contrast, the Sienna’s available display screen measures 9 inches, still a respectable size, but slightly smaller than its competitor. However, what the Sienna lacks in screen size, it makes up for in terms of resolution, offering a higher pixel density for sharper images and text. So, which is more important to you: a larger screen or a more detailed display?

Apple CarPlay and Android Auto Integration

Both the Grand Highlander and Sienna offer seamless integration with Apple CarPlay and Android Auto, allowing you to access your favorite apps, maps, and music on the go. But what sets these vehicles apart is the ease of use and connectivity options. The Grand Highlander features wireless Apple CarPlay and Android Auto integration, eliminating the need for pesky cords and cables. The Sienna, on the other hand, requires a wired connection for these features. If you’re tired of dealing with tangled cords, the Grand Highlander might be the better choice.

Premium Audio Systems and Speakers

For audiophiles, the Grand Highlander and Sienna offer premium audio systems that will transport you to a world of sound. The Grand Highlander’s available JBL Premium Audio System features 11 speakers, including a powerful subwoofer, and a 1200-watt amplifier. The Sienna’s available JBL Premium Audio System, on the other hand, boasts 10 speakers and a 1500-watt amplifier.

Wheelbase and Ground Clearance

Another key difference between the Grand Highlander and Sienna is their wheelbase and ground clearance. The Grand Highlander boasts a 112.2-inch wheelbase and 8.1 inches of ground clearance, making it more suitable for off-road adventures and rough terrain. In contrast, the Sienna has a 118.1-inch wheelbase and 6.5 inches of ground clearance, making it better suited for city driving and smooth roads.

That’s a significant difference, especially if you’re planning to tow a trailer or a boat. However, it’s essential to note that towing capacity also depends on the trim level, engine, and axle ratio, so be sure to check the specifications of your vehicle before hitting the open road.

Cargo Space and Storage Compartments

Roof Rails and Cross Bars

Last but not least, let’s not forget about roof rails and cross bars. These features are a must-have for families who love to adventure or need to transport bulky items like bikes or kayaks. Both the Grand Highlander and Sienna offer roof rails and cross bars, but the Grand Highlander takes it a step further with an available power moonroof and a more comprehensive roof rack system. So, if you’re planning to take your adventures to new heights, the Grand Highlander might be the better choice.
