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

Corvette Grand Sport

The Buick Gran Sport is a performance-focused model name from Buick. In the podcast, it’s mentioned briefly while discussing performance car naming. The point seems to be about what the name refers to rather than detailed specs.

Chevrolet Silverado
Car

Chevrolet Silverado

The Chevrolet Silverado is a large pickup truck made for hauling and towing, but it can also be used like a normal daily vehicle. It comes with different engines depending on the model. The podcast mentions it because of the specific engine options people talk about when comparing trucks.

Corvette
Car

Corvette

The Corvette is Chevrolet’s high-performance sports car. In this segment, they’re using it as the example to talk about how strong the engine is. Then they compare that to what a truck version might deliver.

Concept

torque

Torque is the engine’s pulling power. For towing, you want strong torque so the truck can move a heavy trailer without constantly revving high.

Concept

hybrid system

A hybrid system uses both a gas engine and an electric system. The electric part can add extra power and help the vehicle drive more efficiently.

Toyota Tundra
Car

Toyota Tundra

The Toyota Tundra is a large pickup truck. Some versions use a hybrid system, which combines a gasoline engine with an electric motor. The podcast brings it up because of how that hybrid setup helps the truck move and manage power.

Term

35s

“35s” means tires that are about 35 inches tall. Bigger tires can help a truck go over rough ground more easily, but they can also change how the truck drives.

Term

37s

“37s” are even larger tires than “35s.” They usually make a truck more capable off-road, but they can also require more modifications to fit and drive well.

Company

Carvana

Carvana is a company that buys and sells used cars online. You can enter your car’s info, get an offer fast, and they can pick the car up for you.

Term

horsepower

Horsepower is basically how strong the engine is at producing power. Two engines can have the same horsepower number, but feel different depending on when that power shows up.

Term

RPM

RPM tells you how fast the engine is spinning. If peak power and torque happen at different RPMs, the truck may feel like it needs more revs to get the best performance.

Term

500 pound feet

“Pound-feet” is how torque is measured. They’re pointing out that the peak torque number is still about 500, even though it happens at a different RPM now.

F-150
Car

F-150

The F-150 is Ford’s popular full-size pickup. Here, they’re talking about engine choices for it—specifically that a smaller 2.7-liter option can be cheaper, so you don’t have to pay extra to get a good setup.

Term

margin of error

They’re saying the results won’t be identical every time. Things like weather and how much the truck has been driven can make the numbers look different even if the engines are similar.

2026 Jeep Gladiator 41 edition
Car

2026 Jeep Gladiator 41 edition

This is a special 2026 Jeep Gladiator trim called the “41 edition.” It’s styled like a military/WWII throwback, and the episode points out the unique wheels and graphics.

Car

1945 Willis MB Army Jeep

The 1945 Willis MB was a WWII-era military Jeep. They’re parking the modern Jeep next to it to show the historical inspiration behind the “41” theme.

Term

rear locker

A rear locker helps when the truck is on slippery or uneven ground. It makes the rear wheels work together so you’re less likely to spin one wheel uselessly.

Term

steelies

“Steelies” just means plain steel wheels. They’re usually cheaper and tougher than fancy alloy wheels.

Term

toe box

The toe box is the roomy part of a shoe where your toes go. A wider toe box can feel more comfortable because it doesn’t squeeze your toes.

Concept

EV trucks

An EV truck is a pickup that runs on electricity instead of gas. Because it’s more software- and electronics-driven, it often comes with newer tech features.

Concept

next generation

“Next generation” is basically the next big redesign of a vehicle. Big updates usually happen when the model is fully refreshed, not every year.

Brand

GM

GM is General Motors, the company behind brands like Chevrolet and GMC. They’re being praised here for having strong truck tech and drivetrain options.

Term

clutches

Clutches are friction-based devices used to engage or disengage drive components, often in traction systems like limited-slip or locking differentials. Adding clutch-based features can improve control, but it also requires careful engineering so the clutches can survive high torque and heat.

Term

all-terrain tire

An all-terrain tire is made to handle both regular roads and rougher surfaces. It usually has a tougher tread pattern, which can make it a little louder on the highway.

Term

pretty aggressive

“Aggressive” here describes the tire’s tread design—typically deeper lugs and more open tread blocks. More aggressive tread usually improves off-road traction but can increase noise and sometimes reduce highway comfort compared with milder tires.

Term

white letters

“White letters” means the tire’s sidewall lettering is white instead of the usual color. It’s mostly about how the tire looks.

Company

Mickey Thompson

Mickey Thompson makes tires that are often used for off-roading. The hosts are saying these tires have been getting good feedback.

Term

emissions

Emissions are the harmful gases and particles an engine puts into the air. The hosts are saying emissions rules are a big reason manufacturers might change diesel engine design.

Term

displacement

Displacement is basically the engine’s size—how much space the cylinders move through. Bigger displacement can affect how the engine makes power and how it meets emissions requirements.

Concept

naturally aspirated

Naturally aspirated means the engine pulls in air on its own, without a turbo or supercharger. It’s often simpler and can feel smooth and predictable.

Term

kilowatt hours

Kilowatt-hours (kWh) tell you how much energy is stored in the battery. A bigger number usually means the battery can help longer.

Term

powertrain

Powertrain is everything that turns engine power into motion. It includes the engine plus the parts that send that power to the wheels.

Term

turbos

Turbos are devices that help the engine make more power. Even smaller engines can feel strong and quick when they’re turbocharged.

Concept

Plug-in hybrids

A plug-in hybrid can be charged from a wall outlet, so it can run on electricity more often. The speaker is saying they don’t want that version—at least not if it makes the truck too expensive.
