Silverado's Bold New Chapter
Chevrolet Unveils Redesigned 2027 Silverado 1500: New V8 Power and Cutting-Edge Interior Displays
Key Points
While GM hasn’t published final output figures, dealer/industry reports cited by CarsGuide suggest the new 5.7L LS6 V8 would make about 300 kW/580 Nm and the 6.6L LS6 V8 about 350 kW/680 Nm.
The cabin upgrade is more specific than “bigger screens”: Chevrolet says every trim gets a 16.3-inch center touchscreen and a 12.2-inch digital driver display, while High Country and ZR2 add an 11.5-inch passenger screen, a head-up display, and a rear camera mirror—totaling “more than 60 inches of total screen space.”
Chevrolet also detailed exterior hardware tied to the refresh: a revised nose with LED headlights, tweaked LED tail-lights, chunkier wheel-arch fender and rocker-panel styling, plus standard dual exhaust on the Custom grade and above.
The ZR2 Bison Edition is built in partnership with American Expedition Vehicles (AEV) and adds specific off-road protection and hardware beyond “factory lift packages,” including distinctive front and rear AEV bumpers, rocker protection, 18-inch beadlock-capable wheels, and skid plates protecting the front underbody, transfer case, rear differential, and fuel tank.
GM’s push for new V8s also comes amid recent reliability scrutiny: Benzinga reports GM recalled nearly 600,000 L87-equipped vehicles in the U.S. last year after engine-failure concerns and a later change to oil guidance.
Chevrolet has unveiled the 2027 Silverado 1500, its most significant redesign in years, built on a new platform and powered by two brand-new V8 engines. The truck drops the old 5.3L and 6.2L engines in favor of a 5.7L and a 6.6L V8 — both from GM's sixth-generation "LS6" small-block family — and pairs every single trim with a standard 10-speed automatic gearbox, according to Benzinga.
GM has not released official horsepower numbers yet. But CarsGuide reports the 5.7L is expected to make around 402 hp and 427 lb-ft of torque, while the larger 6.6L should put out roughly 469 hp and 501 lb-ft. Production is set to begin in late 2026, with U.S. deliveries to follow.
New V8s Are a Direct Answer to a Massive Recall
The engine swap is not just a performance upgrade — it is a trust rebuild. GM recalled nearly 600,000 vehicles last year equipped with the outgoing L87 6.2L V8 after engine failures and concerns about oil guidance, according to Benzinga. That recall cast a long shadow over GM's V8 reputation and gave rivals Ford and Ram a talking point.
GM says the new LS6 engines went through an "extensive testing and validation process" focused on durability and dependability. Executive Chief Engineer Mark Dickens emphasized the endurance testing to heavy-use customers. GM is backing that commitment with a $2.2 billion investment across North American plants in Flint, Tonawanda, and St. Catharines to build the new engines, per CarsGuide.
Every Trim Gets a Cockpit Overhaul, Even the Base Truck
The 2027 Silverado's cabin gets a full digital makeover across the board. Every trim — including the base Work Truck — now comes standard with a 16.3-inch center touchscreen and a 12.2-inch digital driver display, according to Automotiveworld. That means even fleet buyers get a big, modern screen as standard equipment.
Step up to the High Country or ZR2, and you get even more. Those trims add an 11.5-inch front passenger screen, a head-up display, and a rear camera mirror. Chevrolet says that adds up to "more than 60 inches of total screen space" in those configurations — a direct shot at the luxury-leaning interiors of the Ram 1500 and Ford F-150 Platinum.
The '350' Name Returns and the Trim List Gets Leaner
Chevrolet is reviving a legendary engine name. The new 5.7L V8 is a direct nod to the classic "350" cubic-inch engine, absent from Chevy trucks for nearly 30 years. At the same time, GM cut the trim count to seven. The long-running LT badge is gone — that core mid-range slot is now simply called "Silverado," according to GM Authority.
The simplified lineup is a strategic move. With GM facing intense pressure from the F-150 and Ram 1500, Chevrolet wants buyers to see clearer value at each price point. Scott Bell, GM's VP of Global Chevrolet, called the 2027 model the "most capable, refined, and advanced" Silverado lineup ever offered.
ZR2 Bison Goes Hardcore With AEV Partnership and Full Skid Plates
The off-road lineup grows with the 2027 refresh. The ZR2 Bison Edition is built in partnership with American Expedition Vehicles (AEV) — a specialist off-road builder. It adds AEV front and rear bumpers, rocker protection, 18-inch beadlock-capable wheels, and skid plates covering the front underbody, transfer case, rear differential, and fuel tank, per GM Authority.
The Bison targets buyers who find the standard ZR2 too tame. Its hardware puts it in direct competition with the Ford Raptor and Ram RHO. Meanwhile, every model in the 2027 range gets revised LED headlights, updated tail-lights, chunkier fender and rocker styling, and standard dual exhaust from the Custom trim up, according to CarsGuide.
