Chevrolet’s redesigned Silverado 1500 is entering significantly more expensive territory at the top of its 2027 lineup. New pricing details show that a Silverado ZR2 equipped with the Bison Edition and the new 6.6-litre V8 reaches US$90,520, including destination, before taxes or additional accessories are considered.
That number reflects more than an engine swap. Chevrolet has redesigned the Silverado for 2027, upgraded the ZR2 with 35-inch mud-terrain tires and new technology, and continued its partnership with American Expedition Vehicles for the Bison. The option sheet also reveals exactly where the money goes—and how a truck already priced above US$90,000 can climb higher.
The Math Behind the US$90,520 Silverado
The starting point is the 2027 Silverado 1500 ZR2, which carries a US$79,995 starting price including Chevrolet’s US$2,795 destination freight charge. Pricing information lists the ZR2 as a Crew Cab Short Bed four-wheel-drive truck, placing it firmly at the top of the regular Silverado 1500 trim hierarchy before special equipment is added. Chevrolet’s High Country begins at US$74,495 including destination, making the ZR2 the most expensive regular trim from the outset.
Adding the ZR2 Bison Edition costs another US$8,020, raising the truck to US$88,015 with its standard Duramax diesel. Substituting Chevrolet’s new 6.6-litre V8 costs US$2,505 on the ZR2. That brings the combination to exactly US$90,520. It is an important distinction that this is still an MSRP calculation rather than an out-the-door figure. State and local taxes, registration, licensing, dealer charges and any additional accessories can move the final transaction considerably higher.
The Bison Package Is a US$8,020 Upgrade
The Bison badge is not simply an appearance package. Chevrolet developed the package with American Expedition Vehicles, better known as AEV, and the 2027 version adds hardware intended to make an already capable ZR2 better protected when trails become rough. Chevrolet says the package includes distinctive AEV front and rear bumpers, rocker protection and 18-inch beadlock-capable wheels, giving the truck equipment that would otherwise require substantial aftermarket work.
Underneath, the Bison receives additional skid-plate protection for vulnerable components. Chevrolet specifically identifies protection for the front underbody, transfer case, rear differential and fuel tank. AEV identification and all-weather floor liners complete the package. That helps explain why the US$8,020 charge is substantial even though the underlying ZR2 already comes equipped for serious off-road use. For an owner who plans to spend weekends navigating rocks, ruts or remote trails, the Bison’s value proposition is built largely around armor and durability rather than additional horsepower.
The New 6.6-Litre V8 Adds US$2,505
One of the most significant mechanical changes for the new-generation Silverado is its 6.6-litre gasoline V8. On the ZR2, choosing that engine adds US$2,505 over the standard powertrain. Chevrolet rates it at 481 horsepower at 5,800 rpm and 501 pound-feet of torque at 4,000 rpm, making it considerably more powerful than the 5.7-litre V8 offered elsewhere in the Silverado range. A 10-speed automatic transmission is used across Chevrolet’s 2027 Silverado engine lineup.
The engine is a new-generation naturally aspirated V8 rather than a turbocharged performance motor. Chevrolet says it uses both direct and port fuel injection along with variable valve timing. The result is a powertrain aimed at buyers who still want traditional large-displacement gasoline performance in a half-ton truck. In the Bison, that creates an interesting combination: specialized AEV trail hardware paired with 481 horsepower. The extra US$2,505 therefore represents more than a minor output bump—it changes the character of Chevrolet’s most aggressive off-road Silverado.
The Duramax Diesel Remains the Standard ZR2 Engine
Spending US$90,520 is not necessary to get a Bison. The regular 2027 ZR2 arrives with Chevrolet’s 3.0-litre Duramax turbo-diesel inline-six as standard equipment, and adding the Bison package to that configuration produces the US$88,015 price. Chevrolet rates the diesel at 305 horsepower and 495 pound-feet of torque, with peak torque arriving at 2,750 rpm. It is also paired with the Silverado’s 10-speed automatic transmission.
That leaves ZR2 buyers with a straightforward choice between two very different personalities. The Duramax offers almost as much peak torque as the 6.6-litre V8 but produces it substantially lower in the rev range, while the gasoline engine delivers an additional 176 horsepower and a slight torque advantage. Chevrolet does not offer the new 5.7-litre V8 on the ZR2. For buyers who spend long days covering highway mileage or value low-rpm diesel torque, the standard engine may remain attractive. The 6.6-litre is the more performance-oriented alternative and the one that pushes the Bison beyond US$90,000.
ZR2 Hardware Is More Serious for 2027
The price increase is arriving alongside a meaningful upgrade to the underlying ZR2. Chevrolet has moved its flagship Silverado off-roader to 35-inch mud-terrain tires for 2027, replacing the 33-inch Goodyear Wrangler Territory MT tires promoted on the 2026 ZR2. The new truck retains a two-inch factory lift and uses Multimatic DSSV dampers, now paired with jounce dampers designed to help control the truck when terrain becomes especially rough.
Front and rear electronic locking differentials are standard as well, giving the ZR2 additional traction when one or more wheels have limited grip. Chevrolet also gives the truck a dedicated off-road hood and Baja drive mode. Those features matter because the Bison does not replace the ZR2’s basic suspension and traction equipment; it builds on it. The result is effectively a layered approach to capability: ZR2 supplies the tires, lockers, suspension and ride height, while the Bison package adds more armor, AEV components and trail-focused protection around that foundation.
The Interior Has Moved Deep Into Premium-Truck Territory
A US$80,000-plus off-road pickup would be a difficult sell if its cabin still felt like a stripped-down trail machine. Chevrolet has addressed that with a significantly more technology-heavy interior. The 2027 ZR2 includes a 16.3-inch central display and Chevrolet says an 11.5-inch passenger display is standard on the ZR2 and High Country. The ZR2 also receives distinctive Torch Red details and genuine forged carbon-fibre trim on the doors and centre console.
Super Cruise is another important part of the equation. Chevrolet makes its hands-free driver-assistance system standard on both the ZR2 and High Country rather than charging ZR2 customers the US$3,105 price listed for Silverado and Trail Boss models. The system can support compatible-road hands-free driving and trailering, although Chevrolet notes that an active plan or trial is required. Underbody camera views, dual wireless device charging and a long list of standard driver-assistance features further blur the line between purpose-built off-roader and luxury pickup. The ZR2 now has to perform convincingly in both roles.
There Are Still Plenty of Ways to Spend More
The US$90,520 V8 Bison figure is attention-grabbing, but the newly detailed option sheet makes clear that it need not be the end of the spending. A panoramic sunroof is listed at US$1,500 on the ZR2, while an extension of Super Cruise-related OnStar coverage to eight years is priced at US$3,000. A different set of 18-inch high-gloss black beadlock-capable wheels is listed at US$770, and decorative rings for compatible beadlock-style wheels appear at US$1,650.
Dealer-installed equipment expands the menu further. Listed ZR2-compatible items include a US$1,299 console cooler, US$695 auxiliary trailer camera, US$1,550 off-road assist steps and US$1,350 hard-folding bed cover. GM Authority’s option breakdown also lists a US$5,499 dealer-installed Performance Package and a US$4,550 performance exhaust for the ZR2. Buyers should not assume every accessory can necessarily be combined with every Bison configuration, but the pricing illustrates how quickly a high-end factory pickup can move beyond its headline MSRP once customization begins.
The Bison Package Itself Barely Changed in Price
One surprising detail is that AEV’s portion of the equation has barely become more expensive. A 2026 Silverado ZR2 Bison window sticker lists the Bison Edition at US$8,010. The newly reported 2027 package price is US$8,020—a difference of just US$10. Much of the higher overall sticker price therefore comes from the new-generation Silverado beneath the package and from the cost of choosing the new V8 rather than a dramatic increase in the Bison package itself.
The comparison also highlights how Chevrolet has shifted some of the ZR2’s capability into the standard truck. The 2026 Silverado ZR2 was advertised with 33-inch mud-terrain tires, whereas the 2027 model moves to 35-inch tires even before Bison equipment is added. That means the 2027 Bison is not simply last year’s truck with more expensive packaging. The foundation has changed significantly. For customers familiar with the outgoing model, the nearly unchanged Bison package price may be less notable than the amount of additional equipment built into the redesigned ZR2.
ZR2 Now Sits Above an Already Expensive Silverado Lineup
The US$90,520 figure becomes easier to understand when viewed against the rest of Chevrolet’s 2027 pricing. Including destination, the Silverado range begins at US$41,395 for a Work Truck. Custom starts at US$46,395, the newly named Silverado trim at US$50,695, Custom Trail Boss at US$57,195 and Trail Boss at US$63,995. High Country enters at US$74,495 before the ZR2 takes over at US$79,995.
That means a V8-powered Bison costs US$49,125 more than the least-expensive Silverado starting figure. The comparison reflects just how broad the modern full-size-truck market has become. Chevrolet is using essentially one nameplate to serve commercial buyers looking for a basic work truck, families wanting a luxury cabin, towing customers and off-road enthusiasts prepared to spend sports-car money on a pickup. The Bison sits at the extreme end of that spectrum, combining the most expensive Silverado trim with an additional specialty package and the largest gasoline engine offered in the light-duty lineup.
US$90,520 Is Best Viewed as the Starting Point for This Specific Build
The most important takeaway is what the US$90,520 number does—and does not—represent. It is the calculated price of a 2027 Silverado 1500 ZR2 with the US$8,020 Bison Edition and US$2,505 6.6-litre V8, based on a US$79,995 ZR2 starting price that already includes US$2,795 in destination charges. It does not include taxes, registration or whatever additional compatible factory and dealer-installed equipment a customer might select.
Chevrolet expects the redesigned 2027 Silverado to become available late in 2026. Until complete production trucks reach dealerships and final configurations can be built through Chevrolet’s consumer configurator, some shoppers may want to treat the newly published option sheet as a detailed preview rather than a final transaction quote. What is already clear, however, is the direction of Chevrolet’s flagship off-road truck: bigger tires, substantially more V8 power, more technology and the continued availability of serious AEV hardware. Reaching US$90,520 is now part of that equation.
