The 2027 Chevrolet Silverado receives a major mid-cycle update, including new 5.7- and 6.6-liter gas V8s and a redesigned interior. In a first-drive review, The Drive reports the 6.6-liter makes 481 hp and 501 lb-ft, while the 5.7-liter is rated at 402 hp and 428 lb-ft. Fuel economy, pricing and some detailed specifications remain unavailable in the source report.
The 2027 Chevrolet Silverado brings two new gas V8s to the pickup’s lineup as part of a substantial mid-cycle update, according to a first-drive review by The Drive. The 5.7-liter produces 402 hp and 428 lb-ft, while the truck-focused 6.6-liter is rated at 481 hp and 501 lb-ft; the update also brings a redesigned interior and changes to the engine lineup.
The Silverado is not a new generation, but The Drive describes the 2027 changes as a heavy mid-cycle update. Along with the redesigned interior, the truck gets new V8 engines, an updated turbocharged four-cylinder and the returning 3.0-liter Duramax diesel. The report says all of the engines are paired with a 10-speed automatic transmission. The reviewer drove the diesel and both V8s, but not the four-cylinder.
The 5.7-liter V8 is the less expensive of the two V8 choices, though the four-cylinder remains the least expensive engine option. It is rated at 402 hp and 428 lb-ft of torque. The Drive characterizes it as a broad-use workhorse and reports a maximum tow rating of 13,700 pounds. That is 200 pounds higher than the Ford F-150 figure cited in the review; the source gives no full towing-trim comparison or testing conditions.
The larger 6.6-liter V8, identified as the L78, makes 481 hp and 501 lb-ft. GM claims those figures give it best-in-class power and torque among light-duty pickups, as reported by The Drive. The review says the engine was developed for truck loads rather than track performance. The 3.0-liter diesel carries over at 305 hp and 495 lb-ft, and gains access to a 34-gallon extended-range fuel tank; The Drive estimates that can allow more than 900 miles between fill-ups, depending on conditions.
Two V8s Set the Silverado Apart
The new engines give buyers distinct choices within a market where towing, hauling and operating costs can shape a truck purchase. The 5.7-liter combines V8 power with the lineup’s more accessible V8 price point, while the 6.6-liter offers higher stated output for buyers who want additional performance. The diesel remains an option for regular towing, with its unchanged output and larger available tank aimed at longer range.
The figures may also matter in competition with other full-size pickups. The Drive’s comparison puts the 5.7-liter slightly ahead of the Ford and Ram V8 power and torque numbers it cites, while the 6.6-liter leads the figures given for Ram’s forthcoming 6.4-liter light-duty V8. Those comparisons are based on the report’s cited specifications, not independent testing. Buyers still need prices, fuel-economy data and trim-specific towing ratings to judge the real-world trade-offs.

A Mid-Cycle Silverado Refresh
The 2027 model is a significant update to the existing Silverado rather than a complete redesign. The Drive identifies the new engine lineup and redesigned cabin as the main changes, while describing the overall truck range as broadly similar to the prior model year. The report says Chevrolet has simplified the lineup somewhat, but does not give a full list of trim changes or equipment differences.
The diesel’s output is unchanged from the outgoing version, according to the review. The 5.7-liter V8 is positioned as a more affordable alternative to the 6.6-liter, which is available on mid-level trims and above. For off-road buyers, The Drive describes the ZR2 as carrying over its lift, Multimatic DSSV shocks and underbody skid protection from 2026. The source does not supply a complete 2027 price or availability schedule.
“This is the ultimate “no notes” engine.”
— The Drive reviewer Byron Hurd, on the 5.7-liter V8
Prices and Fuel Economy Pending
The source report does not provide 2027 pricing, EPA fuel-economy ratings or a complete trim-by-trim specification list. It says the 5.7-liter’s fuel economy was not yet established and the reviewer did not expect a change from 2026, but presents that as a personal expectation rather than confirmed data. The estimated diesel range of more than 900 miles is also dependent on driving conditions and fuel use; it is not a guaranteed distance for every driver.
The review says GM claims best-in-class output for the 6.6-liter, but does not provide an independent comparison across every competing truck configuration. The source also does not detail the four-cylinder’s revised specifications or give a full account of how the redesigned interior differs from the outgoing cabin.
Awaiting Full Specifications
Chevrolet’s 2027 Silverado specifications, pricing and EPA fuel-economy figures will be needed to complete the comparison among the engines and against competing pickups. Buyers should also check the ratings for the exact cab, bed, drivetrain and trim they are considering, since towing capacity can vary by configuration. The Drive’s report is an initial road test of selected engines, not a full review of every powertrain or version.
