Is This Engine Rumor A HOAX? What's The Perfect Truck Engine? | Ep. 324

The Buick Gran Sport is a performance-oriented nameplate associated with Buick models, and it’s brought up in the podcast as part of a conversation that starts with the Corvette Grand Sport. The mention is likely about clarifying or connecting names and categories of performance trims rather than discussing a specific modern truck. In that sense, it’s relevant because it shows how performance branding gets referenced in automotive talk.

The Chevrolet Silverado is a full-size pickup truck built for work and everyday driving, with multiple engine options and configurations. It’s often discussed because its engine families and powertrain choices (including larger V8s) influence how it performs and how it’s compared to other 1500-class trucks. In the podcast, it’s referenced in relation to the 6.2-liter engine and how Silverado/Sierra 1500s fit into the broader truck lineup.

The Chevrolet Corvette is a performance sports car line used here as the reference point for the engine’s output. The discussion ties Corvette-specific engine specs to whether similar performance could make sense in trucks. It’s a key anchor because the rumored truck engine is being compared to what’s already “official” in the Corvette.

Torque is the twisting force the engine produces, and it’s especially important for towing because it helps move heavy loads without needing extreme engine speeds. Truck engines are often tuned to deliver strong low- to mid-range torque to stay effective under sustained load.

A hybrid system combines an internal combustion engine with electric propulsion components. In this segment, they’re comparing how hybrid power can boost output and how the system architecture affects drivetrain behavior.

The Toyota Tundra is Toyota’s full-size pickup truck, known for being offered with hybrid powertrain options. It comes up in discussions about how hybrid systems can change the way power is delivered to the wheels, especially during acceleration and low-speed driving. The podcast specifically references the Tundra’s approach to hybrid operation alongside other full-size trucks.

“35s” means 35-inch tall tires, a common shorthand in truck/off-road circles. Bigger tires can improve ground clearance and off-road capability, but they also affect gearing, ride quality, and fitment.

“37s” refers to 37-inch tall tires, typically an even more extreme off-road setup than 35s. Going from 35s to 37s usually requires more suspension clearance and can increase cost, weight, and drivetrain demands.

Carvana is an online used-car retailer that lets you list a vehicle, get an offer, and schedule pickup—often with minimal paperwork compared to a traditional dealership. In this segment, they’re using Carvana’s process to sell a car quickly and have it picked up the next day.

Horsepower is a measure of how much power an engine produces. It’s commonly used in marketing and spec sheets, but it doesn’t tell the whole story by itself—where peak horsepower happens (RPM) matters too.

RPM (revolutions per minute) is how fast the engine spins. When Ford changes the RPM where peak power and peak torque occur, it can make the engine feel like it “wants” different driving habits (more or less revving) even if the peak numbers stay the same.

“Pound-feet” (lb-ft) is the unit for torque. The speaker is emphasizing that even though the RPM for peak torque moved, the peak torque value remains at a strong, round number—500 lb-ft.

The Ford F-150 is the full-size pickup this segment is focused on, and the host is discussing which engine options are available. The key takeaway is that the 2.7-liter engine is positioned as a more affordable “base” option, which affects how buyers shop and what they pay.

They’re emphasizing that dyno and performance comparisons aren’t perfectly repeatable. Differences in temperature, fuel, and vehicle condition (like mileage) can create small gaps that don’t necessarily mean the engine is truly better.

This refers to a specific 2026 Jeep Gladiator “41 edition,” a special military-themed trim. The “41” nods to Jeep’s WWII-era heritage, and the episode highlights its styling details like wheels, graphics, and interior color.

The Willis MB is a WWII-era U.S. military Jeep, and it’s a major part of Jeep’s historical identity. The segment uses it as a visual reference point to show how modern Jeep “41” themed trucks and SUVs pay homage to that era.

A rear locker is a differential locking feature that forces the rear wheels to rotate together. This improves traction when one wheel loses grip on uneven or slippery surfaces, which is why it’s a common off-road upgrade.

“Steelies” is slang for steel wheels, usually the basic factory wheels (often used on trucks for durability and cost). They’re commonly paired with all-season or off-road tires depending on the build.

The toe box is the front part of a shoe that surrounds the toes. A wider toe box can reduce pressure on the forefoot and help toes spread naturally, which the ad claims improves comfort and posture.

EV trucks are electric pickup trucks, typically using battery packs and electric motors instead of a gasoline or diesel engine. They can offer “more tech” like advanced driver assistance and software features, but they’re also constrained by battery cost, charging infrastructure, and range.

“Next generation” means the redesigned, updated model that typically arrives after a full product cycle. Major changes like new platforms, powertrains, and interior tech often wait for that generation refresh rather than appearing mid-cycle.

GM refers to General Motors, which makes trucks under brands like Chevrolet and GMC. The hosts are crediting GM for leading in hands-free driving systems (in their view) and for offering certain drivetrain options.

An all-terrain (A/T) tire is designed to work on both pavement and light off-road. Compared with highway tires, it typically has a more aggressive tread pattern for traction on dirt, gravel, and mud, but may be noisier at highway speeds.

“White letters” refers to tire sidewalls where the raised lettering is white, creating a visible branding look. It’s a common aesthetic choice on some off-road and street tires, and the hosts are discussing it as part of their tire preferences.

Mickey Thompson is a well-known tire and motorsports brand, especially popular for off-road and performance tire lines. The host is using the brand as an example of tires they’ve tried and that viewers have praised.

Emissions refers to pollutants released by an engine, such as nitrogen oxides (NOx) and particulate matter. The hosts connect emissions to engine design choices—specifically why they think diesel engines might increase displacement to meet regulations.

Displacement is the total volume swept by an engine’s cylinders, usually measured in liters. Increasing displacement can change how an engine produces torque and how it manages combustion and emissions under modern regulations.

Naturally aspirated engines make air flow without a turbocharger or supercharger. They’re often described as simpler mechanically, with more linear throttle response, though they may be less efficient than forced-induction setups.

Kilowatt-hours (kWh) measure battery energy capacity—how much electrical energy the battery can store. More kWh generally means the vehicle can run the electric motor for longer or provide more electric assist.

A powertrain is the combination of components that create and deliver power to the wheels—typically the engine, transmission, driveshafts, and differential. When they say “powertrain,” they mean the whole setup, not just the engine.

“Turbos” refers to turbochargers, which force more air into the engine so it can make more power without needing a larger engine. The discussion suggests that smaller turbo engines can still be fun if they deliver torque effectively.

Plug-in hybrids (PHEVs) use a larger battery that can be charged from an external power source, allowing more electric-only driving than a standard hybrid. The speaker is distinguishing PHEVs from what they want—suggesting they don’t want the added cost or complexity that can come with plug-in systems.
