2020 Toyota Sienna vs 2021 GMC Yukon

The 2020 Toyota Sienna heralded the twilight years of its third generation with a certain old-fashioned charm that some found endearing and others found lacking. Despite updates in 2018 that introduced newer infotainment technologies, the overall feel remained reminiscent of earlier times, highlighted by the hollow "thud" of its doors—a detail not missed by discerning ears attuned to craftsmanship. The interior, lined with controls sourced from a bygone era, paradoxically offered ease of use due to its simplicity. Trims ranged from the utilitarian L to the plush Limited Premium, each with tailored features catering to different family needs, from basic commuting to luxury travel with entertainment options for longer drives. In contrast, the 2021 GMC Yukon presented a complete redesign, ushering an enhanced level of rugged refinement expected from a vehicle straddling the line between utilitarian and luxury. The introduction of an AT4 trim aimed specifically at off-road adventures mirrored GMC's confidence in catering to a more adventurous clientele. A significant upper trim, the Denali, continued to attract those desiring premium features without the premium badge price, though costs climbed considerably when fully equipped. The Denali trim’s exquisite detailing and sophisticated dashboard set it apart, offering a cabin experience that was both premium and distinctly separate from its Chevrolet sibling.

Under the hood of the 2020 Toyota Sienna was a 3.5-liter V6 engine pushing out a solid 296 horsepower and 263 pound-feet of torque, paired with an 8-speed automatic transmission. This setup provided robust acceleration, especially in Sport mode, which sharpened throttle and shift responses for more spirited driving. The available AWD was a boon for those in inclement weather regions, offering additional traction, although it didn't aid in halting the vehicle on slippery surfaces. In terms of efficiency, the Sienna managed decent mileage, with our observations aligning closely with its EPA ratings, particularly notable given its capability of towing up to 3,500 pounds. The 2021 GMC Yukon, particularly in its Denali guise, boasted a muscular 420 horsepower from its 6.2-liter V8 engine, ensuring no shortage of power for any driving scenario. Mated to a ten-speed automatic transmission, the SUV delivered fast and fluid gear changes, enhancing both driving pleasure and operational smoothness. However, this power came at the cost of fuel efficiency, which lagged particularly in configurations with larger wheels. Advanced suspension technologies promised enhanced ride quality and handling, though large wheels could detract from comfort over rough surfaces.

The Toyota Sienna excelled in maximizing interior space—a critical factor for minivan buyers. It offered an impressive 150 cubic feet of cargo space, although accessing this space required removing the second-row seats, which could be cumbersome. The vehicle's layout and inclusion of features like the Auto Access Seat emphasized convenience and accessibility, particularly for those with mobility challenges, making it an accommodating family vehicle. GMC’s Yukon saw a significant improvement in usable space with the adoption of an independent rear suspension in 2021. This adjustment enlarged the passenger and cargo capacity, bringing much-needed upgrades to the third-row seating, which now provided genuine comfort even for adults. Cargo space was ample, with a maximum of 122.9 cubic feet available (up to 144.7 in the XL model), rivaling some minivans. These changes, coupled with added luxurious touches in the Denali trim, such as power-adjustable heated and ventilated seats, positioned the Yukon as a versatile SUV capable of catering to both daily duties and luxurious escapades.

Technology in the 2020 Toyota Sienna catered adequately to contemporary needs. The 7-inch touchscreen, though smaller than those found in some rivals, supported key functionalities like Apple CarPlay which was a welcome, albeit late, addition. Features varied by trim, with higher trims receiving enhancements such as a premium JBL audio system and an innovative Easy Speak intercom, which allowed for communication with rear passengers without distraction. The 2021 Yukon’s tech suite was considerably more advanced, featuring a larger 10.2-inch touchscreen and comprehensive connectivity options including wireless Apple CarPlay and Android Auto. The Denali trim provided an upscale Bose audio system and a sophisticated rear-seat entertainment system with dual displays, though it curiously lacked DVD capability, which might disappoint some users.

Toyota's commitment to safety was evident in the Sienna’s inclusion of the Toyota Safety Sense suite, which offered a comprehensive array of driver aids, from lane-keeping assist to dynamic cruise control. It also boasted exemplary crash-test ratings, reinforcing its family-friendly credentials. The Yukon matched this with a robust set of standard safety features across the lineup, and additional technology in higher trims, such as adaptive cruise control in the Denali. Though crash-test ratings were pending at the time of review, the substantial build and sophisticated assist systems suggested a strong safety proposition.
