virtual locker
"[1931.8s] So the Hummer EV has a virtual locking differential."
It’s a computer trick that makes the car act like it has a lockable differential, but it does so by changing how power is sent to each wheel.
A software‑based simulation of a locking differential that adjusts torque distribution between wheels without mechanical engagement.
Sasquatch 35s
"if you get like a 33-inch tall tire one compared to a Sasquatch on 35s"
Sasquatch 35s are very large tires made for off‑road use, taller than the 33‑inch ones.
Sasquatch 35s are a brand of off‑road tires that are 35 inches tall, offering even more clearance than the 33‑inch option.
33-inch tall tire
"if you get like a 33-inch tall tire one compared to a Sasquatch on 35s"
A 33‑inch tire is a big wheel that lifts the car higher off the ground, useful for rough terrain.
A tire that is 33 inches in diameter, larger than standard passenger tires, providing more ground clearance and potentially better off‑road performance.
unsprung mass
"Because there's a lot less unsprung mass"
Unsprung mass is the weight that sits on the wheels and tires. Less of it makes the car handle better.
The portion of a vehicle’s weight that is not supported by the suspension, such as wheels and tires; lower unsprung mass improves handling and ride quality.
lower center of gravity
"You also, excuse me, you also have a lower center of gravity, right?"
A lower center of gravity means the car’s weight is closer to the ground, making it less likely to tip or roll.
The vertical position of a vehicle’s center of mass; lowering it reduces body roll and improves stability.
suspension geometry
"You change the suspension geometry when you jack a vehicle up that high"
Suspension geometry is how the car’s wheels are set up. Changing it changes how the car drives.
The arrangement of suspension components that determines wheel angles and motion paths; changing it affects handling characteristics.
concept cars
"I mean, that's why designers design all their concept cars with massive wheels and tires."
Concept cars are like design sketches for real cars. They show what a car could look like or do, but they’re not usually sold to the public.
Concept cars are prototype vehicles presented at auto shows to showcase new designs, technologies, or ideas that may influence future production models.
dual sport issue
"And B, there's this inherent compromise and it's kind of the dual sport issue."
When a bike is made to be fast and smooth on paved roads, it might not handle rough trails well. Making it good for off‑road can make it slower on the highway.
The dual sport issue refers to the trade‑off between a motorcycle’s on‑road performance and its off‑road capability. Enhancing one often compromises the other.
on-road vs off-road performance
"What's good on‑road is, except for weight, of course, is different off‑road."
Cars and bikes that are great on smooth roads may struggle on trails, and vice versa. Designers balance these needs based on the vehicle’s purpose.
This concept highlights how vehicle design choices affect handling, weight distribution, and durability differently on paved roads versus uneven or muddy terrain.
wheel travel
"A lot of wheel travel typically bad on-road."
Wheel travel is how much a wheel can move up and down. More movement helps on rough roads, but it can make the car feel less steady on smooth streets.
Wheel travel refers to the vertical distance a wheel can move up and down, usually limited by suspension components. More travel allows a car to absorb larger bumps but can reduce steering precision on smooth roads.
