What is the best Chevy Silverado V8? Can the 5.3-liter V8 hold its own against the big 6.2-liter V8? We compare a 2020 Silverado 1500 RST with a 6.2L and a brand-new Trail Boss with a 5.3L engine. We take both trucks through a rigorous “Buddy Review”. We do a 0-60 MPH acceleration comparison. We take them on a snowy dirt road to test the ride. We compare cabin sound level, comfort, features, and much more.
2020 Chevy Silverado 1500 Trail Boss
The red truck is our long-term project truck that we recently purchased. It’s a higher trim LT Trail Boss crew cab. It’s powered by a 5.3-liter V8 that is the mated to a 10-speed automatic transmission. The truck has a factory two-inch suspension lift and aggressive Goodyear Wrangler Duratrac tires.
The 5.3-liter is rated at 355 hp and 383 lb-ft of torque. The engine is equipped with GM’s latest Dynamic Fuel Management (DFM), which can skip firing certain cylinders under light load – thus improving fuel efficiency.
2020 Chevy Silverado 1500 RST
The other truck is wearing an RST trim (Rally Sport Truck). It’s a double cab (not a full crew cab). It is also equipped with a 4×4 system, and it has new HD towing mirrors. Under the hood is a 6.2-liter V8 with a rating of 420 hp and 460 lb-ft of torque. This engine is also mated to a 10-speed automatic transmission.
Here are the results. We clocked our new Trail Boss 0-60 MPH at 9.46 seconds at a mile above sea level with three people in the truck. This is indeed real world testing.
The RST 6.2-liter truck did the same acceleration in 7.70 seconds on the same route and with same conditions. That is a huge performance gain for the bigger V8.
The ride quality was approximately the same in both trucks, and the RST cabin was just a minute amount less noisy at speed (an impreceptible 1 dB).
The biggest surprise came when we compared the final retail prices for both of these trucks. The loaded 2020 Trail Boss crew cab 4×4 with the 5.3-liter has a sticker price of over $55,000. While the RST double cab 4×4 with everything you see here comes in at around $51,000.
The 6.2-liter is normally a $2,945 premium over the the smaller engine. The way they are configured here makes the big V8 truck significantly less expensive.
