Engine Lineup

The 2027 Chevy Silverado 1500 offers four engine options, including an enhanced TurboMax, the returning Duramax diesel, and two all-new V8 engines. Chevrolet has confirmed the core lineup, while final horsepower, torque, and other specifications will be released separately.

• 2.7L TurboMax I4: The enhanced TurboMax carries into 2027 and is now paired with a 10-speed automatic transmission.
• 3.0L Duramax Turbo-Diesel I6: The proven Duramax returns, offering strong torque and long-distance towing capability.
• 5.7L V8: An all-new sixth-generation small-block V8 replacing the outgoing 5.3L V8.
• 6.6L V8: An all-new sixth-generation V8 that contributes to the Silverado’s most powerful naturally aspirated V8 offering in its class.

What’s Updated?

The biggest powertrain change for 2027 is the introduction of two new V8 engines. The 5.7L and 6.6L V8s replace the previous-generation 5.3L and 6.2L V8s, bringing the Silverado into GM’s next-generation small-block family.

The 2.7L TurboMax also receives an update for 2027 and is now paired with a 10-speed automatic transmission. Meanwhile, the 3.0L Duramax Turbo-Diesel carries over as the Silverado’s diesel option.

The 2027 lineup also changes the trim structure, with LT replaced by the new Silverado trim, while the RST and LTZ trims are no longer part of the Silverado 1500 lineup.

Which Engine Should You Choose?

The right engine depends on how you plan to use your Silverado:

• For everyday driving: The 2.7L TurboMax delivers plenty of torque while keeping things manageable for daily commutes and occasional towing.
• For towing and road trips: The 3.0L Duramax is a great fit if you spend a lot of time towing or covering long highway miles and want the benefits of diesel torque.
• For V8 power: The 5.7L V8 brings the traditional feel of a gas V8, while the 6.6L V8 is the better choice when you want stronger naturally aspirated performance.
• For off-road driving: The 3.0L Duramax is expected to be available on the Trail Boss and standard on the ZR2, giving these purpose-built off-road trucks strong torque for challenging terrain.

Consider your typical towing, hauling, commuting, and off-road needs when deciding which Silverado powertrain makes the most sense.
