GMC Yukon XL trim comparison
2024 GMC Yukon XL SLE vs AT4
The Yukon XL SLE starts at $61,200 while the AT4 is $74,505. That $13,305 gap buys 4 meaningful differences.
The AT4 adds 4WD instead of RWD. If you deal with winter roads or need traction off-pavement, that could be worth $13,305 by itself. If not, the SLE saves you the money.
The SLE is the cleaner fit if RWD already covers the job. The AT4 only earns the extra money when 4WD is the reason you are shopping up.
Think about this as a monthly tradeoff, not just a sticker gap. The AT4 adds about $234/month on a typical 60-month loan, or around $14,040 more overall with interest. The real question is whether 4WD changes your day-to-day use enough to justify paying above RWD.
