General Motors unveiled the 2021 GMC Yukon and Yukon XL back in January during a special media event in Colorado. The all-new flagship SUV enters its fifth generation with this latest ground-up overhaul, and arrives with a revised trim level cadence, redesigned interior, new suspension options, and a whole lot more. Much like the previous generation, the latest 2021 Yukon is once again offered in the extended-length XL body style, and now, we’re getting our first look at the 2021 GMC Yukon XL SLE out on the street.
This is the first time we’ve ever seen the 2021 GMC Yukon XL SLE, in the real world or otherwise. Compared to the standard-length body style, the new Yukon XL adds 15 inches in overall length, measuring in at 225.7 inches versus the 210.7 inches of the standard-length model.
As a reminder, the SLE is the base model in the latest 2021 GMC Yukon trim level cadence. This particular example is also fitted with the base wheel package (RPO code UHN). These wheels measure in at 18 inches in diameter and 8.5 inches in width (45.7 cm by 21.6 cm), and include a six-spoke machined aluminum design with Dark Grey Metallic accents.
This is the only model that is equipped with 18-inch wheels. All other trims get either 20-inch wheels, or 22-inch wheels.
As we exclusively covered earlier this month, the 2021 GMC Yukon Start of Regular Production (SORP) was pushed back to June following delays resulting from the COVID-19 pandemic. The original SORP date was set in May. Moving forward, 2021 GMC Yukon production will begin with SLT and Denali trims, while Phase 2 will commence 13 weeks after SORP and will include SLE and SLT trim levels without restrictions. During this time, SLE trims will comprise five percent of the units produced.
