GM's lineup of brand new full-size SUVs for the 2021 model year represent a substantial improvement over their forebears, but that doesn't mean they'll ship with a massive increase in price. As we reported back in February, the 2021 Chevrolet Tahoe will start at $50,295 - just $1,000 higher than the 2020 model it replaces - despite major tweaks including a new independent rear suspension, and standard safety features like LED lighting and automatic emergency braking.

That said, with a little bit of effort, a shopper can push the price tag up significantly on one of GM's new full-size SUVs. The verdict: load up the 2021 Chevrolet Tahoe as far as it'll go and you'll be staring down about an $86,000 MSRP. This is thanks to the introduction of the High Country trim level, which sits at the top of the new Tahoe and Suburban hierarchy.

However, there's a special package that makes theses premium utility vehicles even more luxurious. Enter the High Country Deluxe Package.

According to a GM website, the High Country Deluxe Package is an absolute alpha of an option when it comes to the 2021 Tahoe and Suburban. This is because it throws in the Max Trailering Package, Panoramic Power Sunroof, Adaptive Cruise Control, Power Assist Steps, and Air Ride Adaptive Suspension.

On top of selecting the "High Country" trim, which starts at $69,600 in the Tahoe ($72,600 for four-wheel-drive), the High Country Deluxe Package commands an additional $5,605. This package is priced the same across all High Country Tahoe and Suburban configurations, be it 2WD or 4WD. A similar offering can be found with the Chevrolet Silverado High Country pickup truck, but is missing things like air suspension.

The power-sliding center console, as previewed on the 2021 GMC Yukon, is also available for $350.

The same High Country trim, which ships standard with GM's stalwart 6.2L V8, is available on the 2021 Chevrolet Suburban at a starting price of $72,300 (2WD). The new trim level renders the Yukon and Suburban more expensive to start than even the Denali versions of the 2021 GMC Yukon and Yukon XL, respectively.

We've recently gotten a good look at some other juicy new pricing details, too. For example, we now know that the 2021 Chevrolet Tahoe Z71, available only in 4WD with a standard 5.3L V8, will start at $59,200, offering a $2,450 "Off-Road Capability Package" with magnetic ride control, adaptive air ride suspension, and an 8-inch digital instrument panel. The same trim level will start at $61,900 on the Suburban.

And, we know that 4WD will cost $3,000 more than 2WD across the board, whether you're shopping the Chevrolet Tahoe, Chevrolet Suburban, or GMC Yukon or Yukon XL. Do with that info what you will.
