The 6.2L EcoTec3 V8 is the highest-horsepower engine Chevrolet offers in the Silverado 1500, the Tahoe and the Suburban. It makes 420 horsepower and 460 lb-ft of torque, and it comes with a 10-speed automatic every time. On all three it is an option rather than the standard engine. Our Chevrolet store in Central Indiana sells and services all three.
Dynamic Fuel Management and Automatic Stop/Start are part of the engine, not options you add on top of it. On a build sheet or a window sticker the engine shows up as L87, Chevrolet's code for it.

The Silverado 1500 offers four engines, and the 6.2L makes the most horsepower of them.
| Silverado 1500 engine | Horsepower | Torque | Transmission |
|---|---|---|---|
| 2.7L TurboMax | 310 hp | 430 lb-ft | 8-speed automatic |
| 5.3L EcoTec3 V8 | 355 hp | 383 lb-ft | 10-speed automatic |
| 6.2L EcoTec3 V8 | 420 hp | 460 lb-ft | 10-speed automatic |
| Duramax 3.0L Turbo-Diesel | 305 hp | 495 lb-ft | 10-speed automatic |
Figures are for the 2026 model year.
Torque runs the other way, and the Duramax 3.0L turbo-diesel leads the four.
Three Chevrolet vehicles use the 6.2L EcoTec3 V8, and all three are full-size.
| Vehicle | How the 6.2L is offered | Drivetrains that carry it |
|---|---|---|
| Silverado 1500 | Available on five trims, standard on none | Four-wheel drive only |
| Tahoe | Available | Rear-wheel drive and four-wheel drive |
| Suburban | Available | Rear-wheel drive and four-wheel drive |
Availability is for the 2026 model year.
In the Silverado 1500, the 6.2L is offered on five trims: the Silverado RST in Crew Cab 4x4, LT Trail Boss, LTZ in 4x4, ZR2, and High Country in 4x4. Every Silverado 1500 configuration that carries it is four-wheel drive, so a two-wheel-drive truck with the 6.2L is not a build you can order. The tailgate badge does not tell you which V8 is underneath, so the build sheet settles it.
The Tahoe and the Suburban both offer the 6.2L in rear-wheel drive and in four-wheel drive. In the Tahoe, the 10-speed automatic is a Hydra-Matic 10L80 running a 3.23 final drive. Both SUVs seat a third row, and the Tahoe is built in seven, eight and nine-seat configurations.
No other Chevrolet carries the 6.2L. The Silverado 2500 HD runs its own engines, a 6.6L gasoline V8 and a 6.6L Duramax turbo-diesel, both on an Allison 10-speed automatic.
On all five trims that offer it, the 6.2L is an upgrade. What you are upgrading from depends on the trim.
| Silverado 1500 trim | That trim's standard engine | How the 6.2L is offered |
|---|---|---|
| RST | 2.7L TurboMax | Available on Crew Cab 4x4 |
| LT Trail Boss | 2.7L TurboMax | Available |
| LTZ | 5.3L EcoTec3 V8 | Available in 4x4 |
| ZR2 | Duramax 3.0L Turbo-Diesel | Available |
| High Country | 5.3L EcoTec3 V8 | Available in 4x4 |
Trim and engine availability for the 2026 model year.
On an RST or an LT Trail Boss that is a two-step jump, from the TurboMax straight past the 5.3L. LTZ and High Country buyers move up one step from a V8 they already have. On a ZR2 it is the gasoline alternative to the turbo-diesel that trim comes with as standard.
The available front bucket seats with a center console are paired with the V8 engines rather than the TurboMax, and that changes how many people fit. A Crew Cab or Double Cab with the standard 40/20/40 split-bench seats six. The bucket-seat build, ZR2 included, seats five.
Trailer ratings change with the configuration, so the number that counts is the one on the truck in front of you.
The Silverado 1500's headline maximum of 13,300 lb is not a 6.2L rating. It requires a Double Cab Standard Bed 2WD with the Duramax 3.0L turbo-diesel and the Max Trailering Package. A 6.2L truck is rated by its own cab, bed and equipment, and each of those moves the figure.
The 6.2L's own ceiling is 13,200 lb, on a 4WD Crew Cab in either bed length with the 3.42 axle, the Max Trailering Package and 20-inch wheels and tires. Put 18-inch wheels under the same truck and it drops to 11,900 lb, which is a bigger swing than most people expect from a wheel choice.
Two ordering notes go with that figure. That package is offered on the LT, RST, LTZ and High Country only, so the trims that can reach 13,200 lb are a shorter list than the trims that can have the engine. And a ZR2 cannot be ordered with it at all.
A ZR2 with the 6.2L is rated at 8,800 lb. That trim is the off-road build, and it carries the hardware to match: a 2-inch factory suspension lift, Multimatic DSSV dampers, front and rear electronic locking differentials, aluminum underbody skid plates and 33-inch mud-terrain tires.
Payload with the 6.2L in a Silverado 1500 Crew Cab runs like this:
| Crew Cab configuration with the 6.2L | Payload |
|---|---|
| 4WD Short Bed | 1,880 lb |
| 4WD Short Bed, lifted | 1,820 lb |
| 4WD Short Bed, Max Trailering | 2,040 lb |
| 4WD Short Bed, ZR2 | 1,520 lb |
| 4WD Standard Bed | 1,820 lb |
| 4WD Standard Bed, lifted | 1,770 lb |
| 4WD Standard Bed, Max Trailering | 1,990 lb |
Figures are for the 2026 model year.
Note which way the Max Trailering rows go: that package adds payload rather than costing it. The ZR2 gives up the most.
For the two SUVs, the 6.2L ratings sort by drivetrain:
| Vehicle with the 6.2L | Payload | Standard trailering | Maximum trailering |
|---|---|---|---|
| Tahoe 2WD | 1,671 lb | 7,700 lb | 8,200 lb |
| Tahoe 4WD | 1,616 lb | 7,600 lb | 8,100 lb |
| Suburban 2WD | 1,612 lb | 7,500 lb | 8,000 lb |
| Suburban 4WD | 1,612 lb | 7,300 lb | 7,800 lb |
Figures are for the 2026 model year.
The Tahoe carries more payload than the Suburban on the same engine, which is what the shorter body buys you. In both SUVs the 3.0L turbo-diesel carries a higher standard trailering rating than the 6.2L does. In a 2WD Tahoe the diesel's standard rating is 8,200 lb against the V8's 7,700 lb, and that 8,200 is the diesel's everyday figure, not a misprint of the 6.2L's maximum in the row above.
On the Suburban rows, the maximum trailering column is the figure with that package fitted, not a rating the truck carries without it.
If you are matching a trailer to a truck or an SUV, bring us the loaded weight rather than the dry weight, and we will check it against the build sheet of the vehicle you are considering.
The 6.2L is the heavier of the two V8s. These are base curb weights rather than matched builds, so read them as the size of the difference, not as a payload calculation.
| Vehicle | Curb weight with the 6.2L | Curb weight with the 5.3L V8 |
|---|---|---|
| Silverado 1500 Crew Cab | 5,180 to 5,550 lb | 4,860 to 5,190 lb |
| Tahoe 2WD | 5,681 lb | 5,509 lb |
| Tahoe 4WD | 5,877 lb | 5,705 lb |
| Suburban 2WD | 5,858 lb | 5,680 lb |
| Suburban 4WD | 6,051 lb | 5,873 lb |
Base curb weights for the 2026 model year. The Silverado range covers Crew Cab configurations.
The gap runs a little under 200 lb on the SUV rows. In the Silverado 1500 Crew Cab it is wider, over 300 lb at either end of the range. If you run close to the payload ceiling every week, check the payload figure on the build sheet before you order.
The 6.2L takes premium fuel in every application.
| Vehicle with the 6.2L | City | Highway | Combined |
|---|---|---|---|
| Silverado 1500 4WD | 15 | 20 | 17 |
| Silverado 1500 4WD, mud-terrain tires | 14 | 17 | 15 |
| Silverado 1500 ZR2 4WD | 14 | 17 | 15 |
| Tahoe 2WD | 15 | 20 | 17 |
| Tahoe 4WD | 14 | 18 | 16 |
| Suburban 2WD | 15 | 19 | 16 |
| Suburban 4WD | 14 | 18 | 16 |
MPG ratings for the 2026 model year. Real-world figures vary with load, terrain and driving style.
In a Silverado 1500 4WD the bigger V8 costs almost nothing in fuel economy. The 5.3L V8 in the same 4WD configuration rates 15 city, 19 highway and 17 combined, which is level with the 6.2L on combined and a point behind it on the highway. The difference shows up at the pump instead, because the 6.2L takes premium and the 5.3L takes regular.
Mud-terrain tires cost more economy than the engine does. They put a 6.2L Silverado 1500 4WD on the same numbers as the ZR2, below the road-tire rows above.
Every new Chevrolet with the 6.2L carries factory powertrain coverage of 5 years or 60,000 miles, whichever comes first. Bumper-to-bumper coverage runs 3 years or 36,000 miles, and roadside assistance runs as long as the powertrain coverage.
You can book service with us through Chevrolet service scheduling.
The 6.2L is the horsepower choice rather than the tow-rating choice. The Silverado 1500's maximum trailering rating belongs to a diesel configuration, and in both full-size SUVs the diesel is rated higher for standard trailering. What the 6.2L gives you is the most power of the four Silverado engines, in a truck or in a full-size SUV with a third row.
If your trailer is modest and most of your driving is unloaded, the 5.3L V8 or the TurboMax will do the job for less at the pump.
Drive the 6.2L and the 5.3L back to back, and pull your own trailer behind them if you can. Come see us in Anderson, or start with our new Chevrolet inventory. Our Chevrolet specials change monthly, so check our new vehicle specials for the latest deals on trucks and SUVs.
On the ratings, the diesel is the towing engine. The Silverado 1500's maximum trailering figure requires a Duramax configuration, and in both full-size SUVs the diesel carries the higher standard trailering rating. The 6.2L is the horsepower answer instead.
Yes, in every configuration. The 5.3L V8 and the 2.7L TurboMax call for regular. Premium is a running cost rather than a one-time one, so it belongs in your monthly math and not in the sticker price.
No. They share a displacement and little else. The Corvette uses the LT2, a different engine entirely. The truck and SUV engine is the EcoTec3 L87.
