General Motors has retired its longstanding 5.3L and 6.2L V8 engines from the 2027 Chevrolet Silverado, replacing them with larger displacement powertrains that increase output but also raise entry costs for top-tier models. The new lineup features a standard 10-speed automatic transmission and significant interior technology upgrades, though the most powerful engine is now reserved exclusively for the two highest-priced trims.
The 2027 Chevrolet Silverado arrives at a moment of transition for the half-ton pickup segment, characterized by both mechanical advancements and a notable shift in pricing strategy. General Motors is retiring its longstanding 5.3L and 6.2L V8 engines from the Silverado and its GMC Sierra counterpart after approximately twelve years of service. In their place, Chevrolet has introduced two new eight-cylinder engines with increased displacement and output, signaling an effort to push the brand further upmarket even as it attempts to maintain affordability in a segment where costs are already rising.
The most powerful addition is a 6.6L naturally-aspirated V8, which Chevrolet claims is the most powerful of its kind in the half-ton segment. This engine produces 481 horsepower and 501 lb-ft of torque. For buyers seeking slightly less power but still requiring robust performance, a new 5.7L V8 offers 402 horsepower and 428 lb-ft of torque. These figures are substantial when compared to the outgoing 6.2L engine, which generated 420 horsepower and 460 lb-ft. The entry-level powertrain remains a turbocharged four-cylinder, now producing 350 horsepower and 455 lb-ft of torque, an increase from the previous model’s 310 horsepower and 430 lb-ft. Additionally, the 3.0L inline-six diesel engine remains unchanged, retaining its position as the only half-ton diesel available in the market.
The introduction of these new powertrains comes with a significant price premium. The largest engine, the 6.6L V8, is now reserved exclusively for the two most expensive trims: the High Country and the ZR2. This restriction means that buyers seeking the top-tier naturally-aspirated engine must pay at least $98,449 before freight for the High Country trim, or $101,194 for the ZR2. This represents a sharp increase from the 2026 model year, where the most expensive V8-equipped Silverado could be purchased for significantly less. The base price for the 2027 Silverado starts at $36,595 for the Work Truck trim, but the cost of entry for high-performance variants has climbed steeply.
During testing east of Tucson, Arizona, the new powertrains demonstrated considerable capability. The 5.7L V8, which is expected to be the volume seller, pairs with a 10-speed automatic transmission that is now standard across the entire Silverado lineup. Reviewers noted that the engine provides plentiful output and smoothness, working seamlessly with the transmission to make the larger 6.6L engine seem almost unnecessary for daily driving. However, the 6.6L V8 delivers a distinct auditory experience, described as roaring with the authority of a muscle car when accelerated.
Both new V8 engines are built in St. Catharines, Ontario, and at two plants in Michigan. The diesel engine, which produces 495 lb-ft of torque available from 2,750 rpm, remains a strong option for towing. Chevrolet estimates the diesel’s cruising range at 1,400 km on a full tank, aided by an expanded fuel capacity of 128 liters, up from 91 liters in the previous model. A larger 28-liter diesel exhaust fluid reservoir also supports long-distance efficiency.
The 2027 Silverado ZR2, priced at $98,699 before freight and additional options, stands out as a high-performance off-road variant. It comes standard with the 3.0L diesel engine, though buyers can opt for the 6.6L V8 for an additional $2,495. The ZR2 features massive 35-inch all-terrain tires, up from the previous 33-inch rubber, and a new Baja drive mode designed to manage drifting on loose surfaces. The truck’s spool-valve suspension isolates the cabin from rough terrain, while new jounce control capabilities in the dampers help soften landings after jumps.
Testing on rocky trails near Redington Pass revealed the ZR2’s capability to handle challenging obstacles with ease. The suspension effectively managed washboard roads and sharp switchbacks, providing a compliant ride that rivals more expensive luxury vehicles. Despite skipping the complex air suspension found in competitors like the Ram 1500, the Silverado maintains its reputation as one of the best-riding trucks in the segment. Even the Trail Boss trim, which typically features stiffer suspension, offers a smooth ride in most driving conditions.
Inside, the 2027 Silverado introduces significant upgrades to materials and technology. The High Country trim features heated and ventilated front seats with massage settings, a first for the truck’s history. A passenger-side display allows for media streaming and gaming without distracting the driver. The interior materials are described as significantly more upscale than previous generations, addressing a long-standing criticism that higher trims felt too similar to base models.
Even entry-level trims benefit from technological enhancements. A standard 16.3-inch touchscreen and a 12.2-inch digital instrument cluster are now included across the lineup. The Google-based infotainment system supports wireless Apple CarPlay, Android Auto, Spotify, Apple Music, and integrated Google Maps. Chevrolet has also expanded its Super Cruise hands-free highway driving system, making it available from the mid-grade Z71 trim upward, rather than being exclusive to the High Country. Super Cruise now works while towing, although it cannot automatically change lanes with a trailer attached.
The 2027 Silverado lineup has been simplified to seven trims, down from nine in the previous year. Chevrolet states that previously optional packages are now included with certain trims to offset typical price increases. However, the cost of ownership for top-tier models has risen sharply. The 2026 RST trim, which started at $75,519, is no longer offered, and the new High Country trim starts at $98,449 before freight.
The redesigned Silverado offers versatility ranging from the utilitarian Work Truck to luxurious land yachts and high-flying off-roaders. While the vehicle’s capabilities have improved markedly, particularly in ride comfort and interior quality, the price of accessing the most powerful engine options has increased significantly. Buyers seeking the sweet-sounding 6.6L V8 must now navigate a higher price barrier, reflecting Chevrolet’s strategy to position the Silverado as a more premium offering in an increasingly competitive market.
