Leadership, like trust, is earned, not awarded.
At GM, our leadership in full-size trucks is a result of something else we earned – customer loyalty. Truck owners, especially at Chevrolet and GMC, are among the most loyal customers in the business. And we've spent the better part of the past two weeks rolling out more details about the next generation of pickups we think they're going to love, and which we think will undoubtedly attract new customers.
The next-generation 2027 Chevrolet Silverado and GMC Sierra light-duty and heavy-duty pickups are on the way, and at their heart are several new powertrain choices that bring the kind of powertrain leadership befitting these trucks, starting with all-new versions of our Small Block V8.
For seven decades, its compact size, lightweight design and interchangeable parts have made the legendary GM Small Block V8 versatile enough to power everything from sports cars to trucks to boats to industrial equipment.
Which, of course, also made it incredibly popular – especially among aftermarket and performance enthusiasts. It’s been a great story for us for 70 years since its debut in the 1955 Chevrolet Corvette and Bel Air.

Now comes the next chapter. We have launched the sixth generation of this time-tested and trusted powertrain in the 2027 light-duty pickups, the Chevrolet Silverado and GMC Sierra – along with variants already powering the Corvette Stingray and Grand Sport.
In the big picture, what we’re trying to accomplish is to build a propulsion portfolio for both the customers of today and the customers of tomorrow.
We are growing our truck and SUV business with advanced gasoline and diesel powertrains, while investing in and developing new EV platforms, batteries, charging systems, and software.
Different customers need different combinations of capability, range, affordability, towing confidence, and convenience. Our aim is to meet them where they are and be ready for where they’re going next – before they get there.
Trucks and SUVs provide the scale, customer relationships, and cash flow to support the investment in the technologies I just mentioned. And GM has the technical breadth, depth and scale that few companies, if any, can match when it comes to developing internal combustion and electric propulsion.

Our agility and flexibility in manufacturing allow us to adjust our production to meet the market wherever it is. You can see the strategy in our industrial footprint. Flint. Brookville. Tonawanda. Our EV manufacturing and battery operations. These are not abstract points on a corporate strategy slide. They are American plants, where American engineering and skilled American workers turn strategy into sheet metal.
That’s our plan to win: To leverage this flexible manufacturing and sourcing footprint to respond quickly to external factors like regulation, trade policy, evolving technology, and demand. We know EVs are the end game of our industry. We’re not walking away from that. At the same time, millions of American truck customers demand specific everyday uses from their vehicles. There is no better option for them than a new Silverado or Sierra powered by one of these new engines.
For more than seven decades, GM engineers, manufacturing teams, and UAW-represented employees have advanced the Small Block V8 from one generation to the next. More than 100 million Small Blocks have been produced across automotive, marine, industrial and performance applications.
As we introduce the new powertrain choices for the next-generation Silverado and Sierra, the message is straightforward: more choice, more capability and more powertrain leadership — with the right engine for every truck customer.
As you might guess, there is no singular Silverado customer or Sierra customer.
They all want a truck that can do whatever they need it to do and deliver the refinement, technology, and comfort they expect every day. Those are different missions that call for different approaches.
That is why the 2027 Silverado and Sierra light-duty pickups offer four distinct powertrain choices, all paired with a 10-speed automatic transmission:
• The enhanced TurboMax, for strong, efficient, everyday capability.
• The 3.0-liter Duramax Turbo-Diesel, for solid low-end torque and effortless highway drivability.
• The heart of today’s story: two all-new Gen-6 Small Block V8s, a 5.7L and a 6.6L, developed from the ground up to meet the demands of full-size trucks.
Both new V8s were shaped around real truck use: towing, hauling, commuting, off-road driving and long-distance travel. They are strong under load, controlled off-road and refined every day. These engines were designed by truck people, for truck people.

The story is the same in our heavy-duty truck lineup. This week, we announced two available powertrains that will launch this year on our 2027 Chevrolet Silverado HD and GMC Sierra HD, delivering more power, control and confidence for truck customers who demand maximum capability every day.
GM’s first all-new in-house-designed heavy-duty diesel engine is a showstopper. The 8.3-liter Duramax turbodiesel V8 delivers power and capability that stomps the competition. That means 1,230 lb-ft of torque and 555 horsepower, numbers that put our Silverado HD and Sierra HD at the top of the heavy-duty food chain.
This Duramax diesel powerplant is GM’s first clean-sheet HD diesel V8. We put all our engineering and pickup-truck knowledge into this engine, and it paid off: Properly equipped HD models offer available maximum towing capacity of up to 38,000 pounds1 with a gooseneck trailer. The new Duramax engine will be built at GM’s expanded DMAX facility in Brookville, Ohio2, thanks to a $920 million investment to expand the facility for high-volume engine production.

For those who prefer gasoline power, the 2027 HD lineup offers an enhanced 6.6-liter gas V8 delivering 412 horsepower and best-in-class3 standard torque of 472 lb-ft. Proudly assembled at GM’s Tonawanda Engine Plant in New York2, this V8 brings the horsepower and torque and improved low-end pulling power that HD truck buyers doing hard work demand.
This roster of light-duty and heavy-duty pickup engines is what powertrain leadership looks like.
It’s not one engine for everybody. It’s the freedom to choose the engine that fits your work, lifestyle, and priorities. And it’s the knowledge and confidence that whichever engine you choose has been thoughtfully designed, thoroughly validated, exhaustively tested, and built with quality. By the time these trucks reach dealerships, our teams will have driven more than 1.5 million miles of real-world, on-road validation for the new V8s.

We know the questions truck customers ask: Will it start every time? Pull what I need? Stay composed under load? Remain durable and refined over years of use?
The answer must be yes, every time.
We’ve worked hard, and invested billions, to get to yes.
This is how we earn the next era of truck leadership: leveraging the might of our American manufacturing operations to produce trucks with a choice of powertrains created by advanced, integrated vehicle engineering and real-world validation.
For Chevrolet, this foundation supports Silverado’s promise of authentic truck capability, strength, and dependability and choice for customers. For GMC, the same engineering foundation enables a Sierra experience that is Professional Grade, premium, and capable.
Two brands. Distinct trucks for distinct customers. But one deep GM advantage: the choice of premium propulsion across the portfolio.
