Dodge Charger
Car

Dodge Charger

The Dodge Charger is a large four-door car that’s built to feel powerful when you drive. People talk about it a lot because it can be sporty and fun, not just practical. In the podcast, they’re likely testing or comparing it to see how it feels in real use.

Term

off-roading

Off-roading means driving on rough or unpaved ground instead of normal roads. They’re saying the event tested the car in more than one kind of driving.

Term

charging

For an electric car, “charging” means putting electricity back into the battery. They’re saying they got to try that part during the trip, not only driving.

Term

top speed

Top speed is the maximum speed a vehicle can reach under its own power. Here it’s used to describe the R2’s highway performance feel, alongside comments about stability.

Tesla Model Y
Car

Tesla Model Y

The Tesla Model Y is an electric SUV that a lot of people use as a reference point. Here, they’re basically saying the Rivian R2 should be compared to how efficient the Model Y is.

Term

kilowatt hour battery

kWh is a way to measure how much energy the car’s battery can hold. A bigger number usually means the car can go farther, if the car uses energy at a similar rate.

Term

off-road tires

Off-road tires have tread meant for dirt and rough ground. They often make the car less efficient on regular roads, so range can drop compared to street tires.

Term

street tires

Street tires are made mainly for driving on regular roads. They tend to waste less energy than more aggressive off-road tires, which helps range.

Term

400 volt

400 volts is the electrical “system voltage” inside the EV. It matters because it affects how easily the car can accept fast charging power.

Term

kilowatts

Kilowatts tell you how much charging power the charger is delivering. More kW usually means faster charging, at least up to the car’s limits.

Term

CCS combos

CCS is a fast-charging plug standard used by many electric cars. “CCS combos” just means the station has the CCS fast-charging ports.

Ford Bronco
Car

Ford Bronco

The Ford Bronco is an SUV made for driving on rough roads and trails. It can also be driven in an open-air way, so when the windows are open it can feel more like you’re outside. That’s why the host is comparing the feeling to a Bronco.

Chevy Silverado
Car

Chevy Silverado

The Chevrolet Silverado is a big American pickup truck. The host is using it as a reference point for how large the Rivian feels.

Ford F-150 Lightning
Car

Ford F-150 Lightning

The Ford F-150 Lightning is Ford’s electric pickup truck. The host mentions it to compare size—saying the Rivian is smaller than the Lightning.

Rivian R1S
Car

Rivian R1S

The Rivian R1S is an electric SUV, meaning it runs on batteries instead of gasoline. The podcast is talking about how it drives—smooth on the highway, but with some noticeable jerky feeling in certain situations. That helps listeners understand what daily driving might feel like.

Term

autonomy

Here, autonomy means how much the car can drive on its own. The host is basically saying the car’s built-in tech determines what it can do, and you can’t easily “upgrade” that later.

Term

Vehicle to grid

Vehicle to grid means your electric car can potentially send power back to the electricity network. The host is treating it as a major feature question for the new Rivian.

Term

vehicle to X

Vehicle to X is a general way of saying the car can send electricity to other places besides just charging. Think “power out of the car” for homes or other equipment.

Term

inverter inside the car is bidirectional

The inverter is the electronics that manage power between the battery and the rest of the electrical system. “Bidirectional” means it can send power out as well as take power in, which is what you need for vehicle-to-home or vehicle-to-grid.

Term

self-drive to level three

“Level 3” means the car can do a lot of the driving by itself in specific situations. But the driver still has to be ready to take over if the system asks.

Term

LiDAR sensor

LiDAR is a sensor that uses lasers to “see” the world in 3D. It helps the car understand distances better, which can make advanced driving features work more reliably.

Rivian R2
Car

Rivian R2

Rivian R2 is an upcoming Rivian electric car. The hosts are talking about how a later version that adds extra sensing tech (LiDAR) could make early versions harder to resell for as much money.

Concept

order book

An order book is basically how many people have already placed orders for a product. The idea here is that demand might be strong enough to keep production plans full.

Term

resell value

Resell value is what you can sell the car for after you’ve owned it. The point being made is that if a better version comes out, early cars may be worth less.

Tesla Roadster
Car

Tesla Roadster

The Tesla Roadster is Tesla’s high-performance electric sports car, historically positioned as a halo product for the brand. In this segment, it’s mentioned as the one Tesla model the speaker hasn’t owned among the other Tesla vehicles available for sale.

Term

FSD

FSD stands for Full Self-Driving. It’s a software system in some Teslas that tries to automate parts of driving, but it still depends on the driver and can be misused.

Term

level four

“Level four” means the car can handle driving on its own in certain areas/conditions without needing the driver to immediately take over. The host is saying level three is different because the driver has to respond during a handoff.

Brand

byd

BYD is the company the hosts are talking about. They say BYD showed a charging technology designed to charge EVs extremely fast, and they’re rolling it out quickly.

Term

zero to 70

“Zero to 70” means going from an empty battery (0%) to about 70% charged. It’s a quick way to compare how fast different charging systems can add usable battery.

Term

Supercharger network

The Supercharger network is Tesla’s network of fast public charging stations. The hosts are comparing how widespread and fast it is versus other charging networks.

Term

station

A station is a charging location. But one station can have more or fewer charging spots, so you can’t compare networks fairly just by counting stations.

Term

stall

A stall is one spot where one car can charge. Two networks can have the same number of sites but very different numbers of cars able to charge at once.

Term

deployment rate

Deployment rate means how fast charging stations (or their capacity) are being rolled out. Higher deployment rate means more charging capability becomes available sooner.

Term

megawatts per month

Megawatts measure how much power a charger can deliver. Saying “megawatts per month” is basically a way to talk about how much new charging capability is being installed each month.

Term

gigawatts

Gigawatts are a bigger unit for electricity power. The episode is using them to compare how large each charging network’s total power capacity is.

Term

super chargers

Superchargers are Tesla’s fast charging stations. The hosts are comparing Tesla’s network to BYD’s, and they’re saying the total charging power matters more than just the raw number of stations.

Term

range

For electric cars, “range” means how far you can drive before the battery runs low. It’s the key number people care about when deciding if an EV fits their routine.

Term

kilowatt hours per 100 kilometers

This is the same efficiency idea as “kWh per 100 miles,” but measured in kilometers. It helps you compare how much electricity the car needs to drive 100 km.

Term

kilowatt hour per 100 miles

This is a way to measure how efficiently an electric car uses electricity. It tells you how many kilowatt-hours it takes to drive 100 miles—less usually means you’ll go farther on the same battery.

Term

battery capacity

“Battery capacity” is the total amount of electrical energy stored in the EV’s battery, typically measured in kilowatt-hours (kWh). In range tests, knowing remaining battery capacity helps explain how much buffer the car had at the end of the drive.

Concept

elevation

Elevation means hills and altitude changes. Going uphill usually drains an EV’s battery faster, so range tests on hilly routes can look worse than on flat roads.

BMW i3
Car

BMW i3

The BMW i3 is a small electric car made by BMW. It was sold in a few different versions, which can matter for features and how it drives. The podcast is likely summarizing those versions so listeners know what they’re looking at.

Term

autonomously ride

“Autonomously ride” means the car can drive itself. In this context, it’s about a self-driving ride-hailing service.

Term

robo taxi

A “robo taxi” is a self-driving taxi you can summon like a rideshare. Instead of a human driver, the car handles the driving.

Term

geofence area

A geofence area is a defined geographic boundary (often mapped in software) where an autonomous or assisted-driving feature is allowed to operate. The host compares Uber’s approach to Tesla’s in Austin, implying Tesla’s self-driving behavior may be limited to a specific mapped zone.

Brand

donut lab

Donut Lab is a battery-tech company. The host is saying their big “miracle battery” claim seems to have failed or stopped working.

Term

solid state battery

Most EV batteries use a liquid inside them. A solid state battery swaps that liquid for a solid material, which could store more energy and be safer—but it’s tough to make in large quantities.

Term

energy density

Energy density is basically how much “power storage” you get from a certain amount of battery weight. More energy density usually means more range without adding as much weight.

Term

cycles of capacity

A battery “cycle” is one full charge and discharge. “Cycles of capacity” is a way to estimate how many times the battery can do that before it starts losing a lot of its usable storage.

Term

fast charge and discharge

Fast charge/discharge means the battery can take in power quickly and also release power quickly. For EVs, that’s important for quick charging and for strong acceleration or repeated hard use.

Concept

independent testing

Independent testing means battery performance is evaluated by an outside lab rather than the company making the claim. For new battery technologies, this is crucial because it helps verify metrics like energy density, cycle life, and charge behavior under controlled, repeatable conditions.

Term

nmc lithium ion battery cell

NMC is a type of lithium-ion battery chemistry. It’s made with a cathode material that contains nickel, manganese, and cobalt, and it’s widely used in EV batteries.

Term

cd coating

“CD coating” here appears to be a specific manufacturing step or surface treatment applied during battery production—likely intended to improve performance or enable a claimed breakthrough. Because the host says the underlying technology “is just not there,” the point is that the coating claim may not translate into real, scalable cell performance.

Term

screen printing

Screen printing is a way to apply a material in a precise pattern using a stencil-like screen. In batteries, it can be used to put coatings onto parts of the cell in a controlled way.

Concept

economic production of those cells

This is about whether the battery idea can be made in large quantities without becoming too expensive. The hosts are saying the breakthrough may not be practical to produce at scale yet.

Subaru Trail Seeker
Car

Subaru Trail Seeker

The Subaru Trailseeker is a version of a Subaru that’s meant for outdoor and adventure use. The podcast is saying it looks like a good choice because it’s set up for that kind of driving. It’s being discussed as a standout option for people who want more than a basic trim.

Subaru R2
Car

Subaru R2

The Subaru R2 is a small car from Subaru. The podcast is saying it could fit well in the market because it offers something that certain buyers want. They’re discussing whether there’s enough demand for this kind of small vehicle.

Term

ultra-fast chargers

Ultra-fast chargers are the really high-power charging stations that can add a lot of range quickly. Your car has to be able to accept that high power for you to get the full benefit.

Term

250

“250” is basically how powerful the charger is. A higher number usually means faster charging, but your car still has to be able to accept that power.

Term

lift kit

A lift kit is a set of parts that raises a car higher off the ground. It can help with clearance, but it doesn’t automatically make a car good at rough off-road driving.

Term

washboard roads

Washboard roads are bumpy, ribbed roads that make the car shake and bounce. Cars with suspension tuned for normal roads can feel rough or struggle there.

Place

California sequoias

The California Sequoias is a remote part of California. The host is using it to show that in far-off areas, EV charging can be harder to find.
