2021 GMC Yukon vs 2021 Toyota Sienna

The 2021 GMC Yukon has been significantly redesigned, enhancing passenger and cargo space through a longer wheelbase and an independent rear suspension. These changes also improve ride and handling, increase payload ratings, and bring a major technology upgrade. However, the new Yukon sees a decrease in tow ratings and in some cases, worse fuel economy compared to its predecessor, marking a mixed progress in its evolution. Conversely, the 2021 Toyota Sienna enters its fourth generation with a comprehensive makeover, introducing a standard hybrid powertrain for the first time. Built on the Toyota New Global Architecture (TNGA-K) platform, it represents a bold step forward in efficiency and design for the minivan segment.

The Yukon's performance receives a lower rating from CarGurus, with a 6 out of 10, while the Sienna excels with an 8 out of 10. The Yukon offers powerful V8 engine options and a future turbo-diesel, but its fuel economy is a downside. Its ride quality and handling benefit from suspension upgrades, though large wheels can detract from comfort. In terms of towing, the Yukon is a much better option than the Sienna minivan. However, rhe Sienna's hybrid powertrain delivers efficient and smooth performance, with improved handling over its predecessor and impressive fuel economy ratings. Its electronically controlled CVT and available AWD system ensure a comfortable ride across various conditions.

The 2021 GMC Yukon's redesign significantly enhances its form and function, providing notable improvements in passenger and cargo space thanks to its new independent rear suspension. This modification addresses previous criticisms about space constraints, offering substantial gains. The front-seat room remains largely unchanged, but enhancements include luxurious leather upholstery and advanced comfort features in the Denali trim, such as 12-way power-adjustable, heated, and ventilated front seats. However, the seats may feel hard over long drives, and the lack of a massage function is notable. The second-row seating now features a sliding and collapsing mechanism for easier access and improved comfort, with heated seats standard in the Denali. The third-row seating is significantly more comfortable and spacious, making it suitable for adults and providing genuine thigh support. Cargo capacity is impressive, with the Yukon Denali offering 25.5 cubic feet behind the third row, 72.6 cubic feet with the third row folded, and up to 122.9 cubic feet with both the second and third rows down. The extended Denali XL versions offer even more space, with 41.5 cubic feet behind the third row, 93.8 cubic feet with it folded, and a maximum of 144.7 cubic feet. The 2021 Toyota Sienna, designed with an emphasis on convenience and functionality, excels in catering to both drivers and passengers across all rows. The minivan's interior is thoughtfully designed to maximize comfort and utility, featuring a standard third row and a highly adjustable second row that slides up to 25 inches for easy access but cannot be fully removed. Storage solutions are abundant, with cubby spaces and up to 16 cupholders ensuring that everything has its place. The Sienna's cargo capabilities are equally impressive, ready to handle family needs with 33.5 cubic feet of space behind the third row, 75.2 cubic feet behind the second row, and up to 101.0 cubic feet with the second row leaned forward. Its towing capacity of up to 3,500 pounds, along with a smartly integrated 288-volt Nickel Metal Hydride battery that doesn't impinge on cargo space, highlights Toyota's commitment to practicality and efficiency. Power-operated doors and tailgate, responsive to kick motions, further underscore the Sienna's family-friendly appeal.

Both vehicles are highly rated for technology, each earning a 9 out of 10. The Yukon's Denali trim features a comprehensive suite of infotainment and connectivity options, including a 10.2-inch touchscreen and advanced rear-seat entertainment. The Sienna matches this with a robust offering of standard and available tech, including a 9-inch touchscreen and a variety of connectivity services across all trim levels.

The Yukon and Sienna are equipped with advanced safety technologies, though the Yukon scores higher with a 9 out of 10, compared to the Sienna's 7 out of 10. The Yukon's array of driving assistance systems is extensive, especially in higher trims. The Sienna also offers a comprehensive safety package, including Toyota Safety Sense 2.0, though its overall safety rating is slightly lower.

The Sienna is rated higher for cost-effectiveness, scoring an 8 out of 10, against the Yukon's 5 out of 10. The Yukon's towing capability and luxurious features are tempered by its higher costs and less impressive fuel economy. The Sienna, with its competitive pricing, comprehensive warranties, and hybrid efficiency, presents a strong value proposition, particularly for families.
