About this episode

A quick news roundup kicks things off with vehicle kill switch regulation, new EVs, and Polestar adding Google Gemini AI. The hosts then shift to the week’s test vehicles: a 2026 Honda Ridgeline Trail Sport and the 2026 Jeep Grand Cherokee Summit. The Summit gets attention for its larger infotainment screen and a new turbocharged four-cylinder with dual spark plugs, plus heated, upscale materials and practical cargo space. Value and real-world torque feel are debated, alongside connected-car and charging topics.

Technical Too Afraid to Ask
Term

appearance packages

"Yeah, I have mixed emotions about appearance packages being made into standalone trim levels. [355.8s] What I'll say about this one, though, is the Ioniq 9 had kind of a funky look to it..."

An appearance package is a set of “looks” upgrades, like styling details. The host is saying it’s a little odd when those cosmetic options are sold as their own separate trim level.

Term

torque

"So in terms of an appearance package, I think they did a good job with the styling, [370.3s] and you can't argue with the performance. [372.7s] The performance is just, it blows your way, 422 horsepower, more than 500 pound feet of torque,"

Torque is the “pulling power” that helps the vehicle accelerate. Higher torque usually means it feels stronger when you start moving or press the pedal.

Term

10 to 80% in 24 minutes

"I mean, that's one of the advantages of the Ionix, is they charge fairly rapidly, 10 to 80% in 24 minutes, this under ideal conditions."

They’re quoting how quickly the battery can be charged. Going from 10% to 80% is a common test because charging tends to slow down as the battery gets fuller.

Term

assembled in Georgia

"It's going to be assembled in Georgia. I was at the plant fairly recently, where this is being assembled outside Savannah, Georgia."

They’re talking about where the vehicle is made. That can affect how easily the factory gets parts and keeps production running smoothly.

Company

Kia factory

"Yeah, I was at the Kia factory not far from where you were, and they talked a lot about it, and the amount of parts sharing and logistics that they have arranged down there is really, really interesting."

They mention the Kia plant to talk about how car companies organize parts and shipping. The goal is to make sure the factory gets the right parts at the right time.

Term

range of roughly 300 miles

"$30,000 EV truck from Ford, a mid-size EV truck, again, targeting a $30,000 price point, range of roughly 300 miles. All that sounds pretty good."

Range is how far the EV can go on one charge. “300 miles” is an estimate, and real driving conditions can make it more or less.

Term

targeting a $30,000 price point

"$30,000 EV truck from Ford, a mid-size EV truck, again, targeting a $30,000 price point, range of roughly 300 miles. All that sounds pretty good."

They’re talking about Ford trying to sell an EV truck for around $30,000. The hosts doubt it will actually end up that cheap.

Car

Ford Maverick

"I would say one of the things that has me scratching my head a little bit is Ford sells the Maverick truck. The small truck sells very well, and it's F-150, full-size truck sells very well."

The Ford Maverick is a smaller pickup truck. They’re bringing it up because it sells well, and they’re comparing that to how Ford’s other truck sizes do.

Car

Ford F150

"The small truck sells very well, and it's F-150, full-size truck sells very well. It's mid-size truck, not so much."

The Ford F-150 is Ford’s big, popular pickup truck. They’re using it as an example of how well Ford trucks sell overall.

Car

Ford F-150 Lightning

"Yeah, we've been hearing about this truck since the Lightning debuted in 2020 or 2021, and the 2027 launch date, that's six or seven years Ford has been working on this."

The Ford Lightning is Ford’s electric pickup. They mention when it first came out to explain how long Ford has been working on the next EV truck.

Term

unskeptical

"I'm going to say unskeptical that they end up releasing this at the price point that they promise. I think this is one of those I'll believe it when I see it moments."

They’re basically saying they don’t fully believe the promise yet. They think the final product might not match the marketing claims.

Concept

hybrid form

"But as you say, the Maverick sells pretty darn great, and it's very efficient in the hybrid form. It's pretty capable for what people need it to be, and it's comfortable to drive."

A hybrid uses both gas and electricity. It can save gas, especially in stop-and-go driving, because the car can use the electric motor sometimes and recharge while slowing down.

Car

Ford Ranger

"And then also you said the slower sales of the Ranger, which sits right in the middle. I mean, they are putting preparations for this to build this at the Louisville plant."

The Ford Ranger is a mid-size pickup truck. The hosts are using it as a comparison point for where Ford’s truck lineup sits in terms of size and market positioning.

Company

Louisville plant

"I visited the Louisville plant about a year ago. It's an interesting plant there, a very major plant that builds a lot of trucks. So this is going to come to fruition."

The Louisville plant is a factory where trucks are built. If a new truck is planned for that factory, it can influence how soon it’s available and how many can be made.

Concept

large casting of pieces of the body

"So I don't know. Some of the methods they're going to use to achieve this also have kind of mixed outcomes, right? This large casting of pieces of the body. It's great for saving costs. But if you get a little bit of a wreck later on,"

Instead of making the body from lots of smaller parts, the manufacturer uses bigger cast sections. That can save money to build, but if the car gets wrecked, fixing those big sections may cost more than you’d expect.

Car

Chevrolet Corvette

"...at I did as a automotive journalist was driving a Corvette from Chicago to Los Angeles."

The Chevrolet Corvette is a sports car designed to be fast and fun to drive. The host mentions driving it across the country to see how comfortable and practical it is for a long trip. That’s why it comes up in the conversation.

Brand

Google Gemini

"[686.0s] Postar is rolling out Google Gemini in its in-car technology. [691.8s] Beyond Google built in, it also has AI."

Google Gemini is an AI “helper” made by Google. In cars, it’s meant to understand what you say and help with things like voice commands and other responses.

Term

voice command situation

"[704.8s] Again, I'm not sure who's asking for this, but I'll say this. [707.7s] Like I think if anything that can improve the voice command situation [711.2s] is probably going to be a good thing for people who use voice commands regularly."

This is about how well your car listens to you when you talk to it. The better the system, the fewer times you have to repeat yourself and the easier it is to use without touching your phone.

Concept

privacy things

"[721.1s] I think if that's the case here, that's great. [723.8s] I just have questions about the other functionality and again, [727.2s] some privacy things and things like that. [729.2s] So AI doesn't have to be in everything."

In-vehicle AI raises privacy concerns because voice and interaction data may be collected, processed, or stored to improve responses. Listeners should consider what data is used, how long it’s retained, and whether it can be controlled or deleted.

Brand

Google Assistant

"[729.2s] So AI doesn't have to be in everything. [732.0s] But apparently it's going to be there and it's going to replace the present Google Assistant. [738.4s] So remind us of your test vehicle for this week, Chris."

Google Assistant is an older voice assistant system from Google that some cars use. The hosts are saying it may get replaced by Gemini for smarter AI responses.

Car

2026 Honda Ridgeline Trail Sport

"[738.4s] So remind us of your test vehicle for this week, Chris. [741.8s] I had the 2026 Honda Ridgeline Trail Sport."

The Honda Ridgeline is a pickup truck that’s built more like an SUV, not like the heavy-duty trucks with a separate frame. The Trail Sport version is the more adventure/off-road-oriented trim, meant for dirt roads and tougher conditions.

Term

3.5 liter V6

"So it's Honda's Trident True 3.5 liter V6. It's 280 horsepower, 262 pound-feet of torque."

This means the engine has six cylinders, arranged in a V shape, and it’s 3.5 liters total. It’s a common engine layout that helps balance smoothness and usable power.

Term

nine-speed automatic transmission

"It's paired with a nine-speed automatic transmission. You get all-wheel drive with this truck."

This is the car’s automatic gear box, and it has nine different gear settings. More gears can make the car feel smoother or more efficient, but it depends on how the car is programmed.

Term

all-wheel drive

"You get all-wheel drive with this truck. This is their sort of off-roady variant here."

All-wheel drive means power goes to all four wheels. That usually helps the car grip better on wet, snowy, or rough roads.

Term

off-roady variant

"This is their sort of off-roady variant here. 5,000 pounds of towing, which is pretty solid."

This is a version of the vehicle meant to handle dirt roads and rougher conditions better than the basic model. It’s more about traction and clearance than extreme off-roading.

Term

towing

"5,000 pounds of towing, which is pretty solid. A 1,521-pound payload capacity for the Trail Sport trim."

Towing is how much weight the vehicle can safely pull behind it. The number they quote is the vehicle’s rated limit for trailers.

Term

payload capacity

"A 1,521-pound payload capacity for the Trail Sport trim. I think you get like 17 more pounds of payload in the lower trim levels."

Payload capacity is the maximum weight you can put in the vehicle—people and cargo. If you load more than that, the car can become unsafe and handle poorly.

Term

all-terrain tires

"Jack, you get all-terrain tires with the Trail Sport. But one thing that's obvious driving this vehicle"

All-terrain tires are built to work on both paved roads and rougher surfaces. They usually grip better off pavement, but can be a bit noisier.

Concept

body-on-frame pickup truck

"But one thing that's obvious driving this vehicle is that it is not a body-on-frame pickup truck. This thing feels a lot like a crossover, even the Honda Odyssey."

Some trucks are built with a separate heavy frame underneath, and the body sits on top of it. This one doesn’t feel like that kind of truck—it drives more like a regular crossover.

Car

Honda Odyssey

"This thing feels a lot like a crossover, even the Honda Odyssey. It drives a lot like the Honda Odyssey."

The Honda Odyssey is a minivan that’s built to feel smooth and comfortable. They’re saying this vehicle drives in a similar, easy-to-live-with way.

Term

V6 engine

"The V6 engine, as it is in other vehicles, is very capable. It makes a good noise. I'd always like Honda's V6."

A V6 engine has six cylinders arranged in a V shape. It’s a common engine type that usually gives good power and smooth driving.

Term

clunky off the line

"Yeah, and one thing I'll say, and I've noticed that with the pilot that I have this week, is that automatic transmission feels a little bit clunky off the line."

“Clunky off the line” describes a rough or delayed feel when starting to move from a stop. With an automatic transmission, this can come from shift timing, torque converter behavior, or how the transmission manages low-speed throttle response.

Term

hunting for gears

"It feels like it's hunting for gears. There are a lot of shifts before it kind of settles out and you reach speed."

“Hunting for gears” means the car keeps changing gears back and forth instead of staying in the right one. That can make the ride feel jerky or not very smooth.

Term

heated steering wheel

"So pretty nice there. You get heated front seats and a heated steering wheel. Five-person seating capacity."

A heated steering wheel uses an internal heating element to warm the wheel surface. It’s a comfort feature that helps reduce cold-weather numbness and improves drivability in winter.

Car

Honda Passport

"They're about the same feel as in a Honda Passport. So you get two rows of seating here."

The Honda Passport is another SUV they’re using as a benchmark. They’re basically saying the back-seat feel is similar to what you’d get in a Passport.

Term

lockable storage

"One thing I really liked is, you know, the bed is a decent size, but under the bed, you get lockable storage. So there's a compartment that opens, and it's a really deep storage space back there..."

Lockable storage is a hidden compartment you can lock. It helps keep things out of sight and harder to steal when you’re using the truck bed.

Term

sunroof

"And then higher trims of the passenger, the ridgeline, excuse me, come with a sunroof. So you're getting things that you don't normally get in a pickup truck."

A sunroof is a panel in the roof that lets in more light, and sometimes fresh air. It can make the cabin feel brighter and more open.

Term

digital gauge cluster

"You get a seven-inch digital gauge cluster and a nine-inch touchscreen, no matter which ridgeline you choose."

Instead of regular dials, the car uses a screen behind the steering wheel to show things like speed and other driving info.

Term

touchscreen

"You get a seven-inch digital gauge cluster and a nine-inch touchscreen, no matter which ridgeline you choose."

The touchscreen is the big screen in the center of the dashboard you use to control the car’s media and phone features.

Term

wireless Apple CarPlay

"Wireless Apple CarPlay and Android Auto are standard along with wireless phone charging, which I thought was nice for every trim."

Apple CarPlay lets your iPhone show maps, music, and messages on the car’s screen. “Wireless” means you don’t have to plug the phone in every time.

Term

Android Auto

"Wireless Apple CarPlay and Android Auto are standard along with wireless phone charging, which I thought was nice for every trim."

Android Auto is how an Android phone connects to the car’s screen for things like directions and music. It can work wirelessly or with a cable.

Term

wireless phone charging

"Wireless Apple CarPlay and Android Auto are standard along with wireless phone charging, which I thought was nice for every trim."

Wireless charging powers your phone by placing it on a charging pad in the car. The phone doesn’t need a cable, but it may charge slower than plugging in.

Term

wired connection

"It seems to like a wired connection first, and then it asks you if you want to go wireless after that. But I just usually use the cord in these vehicles and still charges faster than the wireless phone charger."

Using a cable to connect your phone to the car can make the connection more reliable and sometimes charges the phone faster.

Term

infotainment

"What do you think of Honda's infotainment check? I think it's okay. And I think it's improved."

Infotainment is the combined system for information and entertainment in the car, typically including the touchscreen, audio controls, navigation, and phone integration. It’s a key part of the daily usability of modern vehicles.

Term

Sirius XM radio

"the Ridgeline comes with Sirius XM radio. The new pilot that I have this week does not."

Sirius XM is a satellite radio service. The hosts are saying some newer Honda models don’t include it, so you can’t easily set up your kid’s station the same way.

Car

Honda Pilot

"The Ridgeline comes with Sirius XM radio. The new pilot that I have this week does not."

The Honda Pilot is a family SUV with three rows. They’re comparing it to other Hondas and pointing out that this one doesn’t come with satellite radio.

Term

Honda Sensing Safety Equipment

"Beyond that, you get Honda Sensing Safety Equipment as standards. So you get lane keep assist, forward collision alerts, all those things."

Honda Sensing is a set of safety and driver-assist features. It can help with things like staying in your lane and warning you if you’re getting too close to a car ahead.

Term

lane keep assist

"So you get lane keep assist, forward collision alerts, all those things."

Lane keep assist helps you stay in your lane. If the car thinks you’re drifting, it can nudge you back or warn you.

Term

forward collision alerts

"So you get lane keep assist, forward collision alerts, all those things."

Forward collision alerts use sensors (typically cameras and/or radar) to detect vehicles or obstacles ahead. If a potential crash is detected, the system warns the driver—often with visual and audible alerts—so you can brake or steer in time.

Term

adaptive cruise control

"The higher trims come with blind spot monitoring and rear cross traffic alerts and adaptive cruise control."

Adaptive cruise control is like cruise control, but it also reacts to the car in front of you. If traffic slows down, it can slow the vehicle too to keep a safe gap.

Term

rear cross traffic alerts

"The higher trims come with blind spot monitoring and rear cross traffic alerts and adaptive cruise control."

Rear cross traffic alerts warn you about cars coming from the sides while you’re reversing. It helps prevent accidents when backing out of a driveway or parking space.

Term

blind spot monitoring

"The higher trims come with blind spot monitoring and rear cross traffic alerts and adaptive cruise control."

Blind spot monitoring helps you notice cars in your blind spots. If there’s a car next to you and you try to change lanes, it will warn you.

Car

2026 Jeep Grand Cherokee Summit

"Well, I'm going to talk about the 2026 Jeep Grand Cherokee Summit. It sits at the top of that lineup."

This is a Jeep Grand Cherokee, which is an SUV meant to handle both normal driving and tougher terrain. “Summit” is a higher trim level, so it’s usually more equipped than the cheaper versions.

Term

turbo-charged four-cylinder engine

"And then it has this new turbo-charged four-cylinder engine, which I think is the big story here."

A turbocharged 4-cylinder engine uses a device (a turbo) to cram more air into the engine. That helps a smaller engine feel stronger, and it’s a major change the host is evaluating.

Term

dual spark plugs

"It uses dual spark plugs. And the way the gas is sprayed into the combustion chamber is different."

Dual spark plugs means there are two ignition points per cylinder. That can help the fuel burn more evenly, which can improve efficiency and smoothness.

Term

combustion chamber

"And the way the gas is sprayed into the combustion chamber is different."

The combustion chamber is where the engine actually burns the fuel. If the fuel is sprayed differently into that space, it can change how well the engine runs.

Term

V6

"Would I go with the old V6, which also has had some issues, I think, the Pedestar V6, or would I go with this new turbo-charged four-cylinder?"

A V6 is an engine with six cylinders arranged in a “V” shape, typically used for smoother power delivery than a smaller 4-cylinder. Here, the host is comparing the older V6 option against the new turbocharged four-cylinder to decide what they’d choose.

Term

fuel economy regulations

"And I think this is kind of a remnant, Chris, of fuel economy regulations that are now pass A."

Fuel economy regulations are government rules that require vehicles to meet targets for how efficiently they use fuel (often measured as miles per gallon or equivalent metrics). The host suggests the engine choice is a “remnant” of these rules, implying the move toward smaller turbo engines is partly policy-driven.

Term

turbo-charged engine

"oh, we have to do a turbo-charged engine for this vehicle to get fuel economy to where it needs to be so we could sell it."

A turbo-charged engine uses a device that squeezes more air into the engine. More air helps the engine make more power without needing a bigger engine.

Term

V8

"And maybe you could get even a V8 in this thing, or you'd be just as well off."

A V8 is an engine with eight cylinders. People often like V8s because they can feel strong and responsive, especially when you accelerate from low speeds.

Term

horsepower

"You get a 324 horsepower, that sounds good. It didn't really, to me, feel as strong as that."

Horsepower is a number that describes how much power the engine can make. But a car can still feel less impressive if the engine doesn’t deliver strong pull at low speeds.

Term

high-stress four-cylinder engine

"but a smaller high-stress four-cylinder engine and a vehicle like the Jeep Grand Cherokee just feels like something that buyers aren't going to warm to."

A “high-stress” engine is being pushed harder to make power. The hosts are saying that, in a heavy SUV, that can make the driving feel less satisfying than you’d expect.

Term

hemi

"And they've offered the hemi in that vehicle for a long time, and now they don't. I wouldn't be surprised to see it come back."

“Hemi” is a type of engine design that Chrysler used on some performance V8s. In this discussion, they’re saying the Grand Cherokee used to offer that kind of V8 and now it doesn’t.

Term

powertrain

"I'm just not sure of the powertrain these days. Which powertrain I would pick."

A powertrain is what makes the car move—basically the engine and the parts that send its power to the wheels. The hosts are saying they’re unsure which version they’d choose.

Term

Uconnect 5

"Yeah, I like Uconnect 5. I think it's a great infotainment system. It's easy to use. It's packed with features."

Uconnect 5 is the Jeep’s touchscreen system inside the car. It controls things like music, navigation, and settings, and the host says it’s simple to use and packed with features.

Concept

EVs

"[1530.5s] but you understand all kinds of stuff about EVs, don't you? [1533.8s] I tried it."

EVs are cars that run on electricity from a battery. Instead of burning gasoline, they use an electric motor to move the car.

Concept

ICE and combustion engines

"[1558.3s] Well, the market itself originally started out with [1562.5s] ice and combustion engines."

ICE just means the usual gas or diesel engine that burns fuel. It’s the opposite of an electric-only powertrain.

Concept

plug-in hybrid

"[1569.9s] and these include technologies like hybrid, [1573.0s] plug-in hybrid, and BEVs, or full electric vehicles."

A plug-in hybrid is part gas, part electric—but you can charge it by plugging it in. That means you can often drive on electricity for a while before using gas.

Concept

hybrids

"with other electrified vehicles, plug-in hybrids and potentially hybrids, I imagine."

In automotive terms, hybrids combine an internal-combustion engine with an electric motor. Unlike plug-in hybrids, many hybrids can’t be charged from an outlet and instead rely on regenerative braking and the engine to recharge the battery.

Concept

automation

"we've made the plant to be smart and flexible with a lot of automation and a lot of efficiencies built in."

Automation means robots and machines doing parts of the car-building process. It can make production faster and more consistent.

Concept

EV-only plant

"So you're correct, it was originally started as an EV-only plant, but we're now making adjustments to be able to accommodate other types of powertrains and vehicles."

An EV-only plant is a factory set up to build electric cars only. Here, they’re saying they’re adapting it so they can build other kinds of cars too.

Term

ICE engine

"they may be at that crossroads where they may contemplate to make that switch from an ICE engine, maybe to a hybrid or even a full BEV."

ICE engine means a regular gas or diesel engine that burns fuel to move the car. The hosts are talking about whether people will switch from these to electric options.

Term

full BEV

"maybe to a hybrid or even a full BEV."

A BEV is a fully electric car. It runs on electricity from a battery, not a gas engine, so you charge it instead of buying gas.

Term

battery electric vehicles

"and then full battery electric vehicles among the leading engine on the battery electric side."

Battery electric vehicles are electric cars that use a battery to power the motor. They’re one of the main alternatives to gas engines.

Term

Hydrogen

"Hydrogen too. Yes."

Hydrogen can be used in cars to make electricity on the spot. Instead of using a gas engine, a fuel cell turns hydrogen into power to drive the car.

Car

Hyundai Kona EV

"So we've got, on the Hyundai side, we've got a Kona EV. We also have our IONIQ 5, our IONIQ 9."

The Hyundai Kona EV is a fully electric SUV/crossover. Instead of using gas, it uses a battery and an electric motor.

Car

Hyundai IONIQ 5

"The IONIQ 5 really was our stand-up and continues to be our stand-up model in our lineup. IONIQ 9 was just recently introduced."

The Hyundai IONIQ 5 is an all-electric Hyundai crossover. The hosts are saying it’s one of Hyundai’s main EVs and has been a big part of their lineup for a while.

Car

Hyundai IONIQ 9

"IONIQ 9 was just recently introduced. We've also introduced new additions to the IONIQ 9 in terms of features and capabilities... I mean, the IONIQ 9, and I've had a chance to test it."

The Hyundai IONIQ 9 is a newer Hyundai electric vehicle. In this segment, they talk about it getting extra features and that the host has driven it and thinks it feels especially close to what people expect from an EV.

Concept

non-combustion EV alternatives

"There are people that still continue to seek out non-combustion EV alternatives today."

Non-combustion means the car doesn’t burn fuel like a typical gas engine. The hosts are talking about EV-style options that avoid that kind of fuel burning.

Concept

battery electric (BEV) adoption

"the removal of the tax incentives really brings to light who's winning in the EV race... the market has been about 7% battery electric... take roughly 10 to 20 years where we'll start seeing share increase beyond the current 5% to 7%"

A battery-electric car is powered only by electricity from a battery. “Adoption” here means how many people will buy them over the next several years, not just whether they exist.

Concept

tax incentives

"the removal of the tax incentives really brings to light who's winning in the EV race... measures what the true market demand of EVs is without that additional subsidies of rebates"

Tax incentives are money the government gives (or reduces taxes) to make certain cars cheaper to buy. The hosts are saying that without those breaks, you can better see what people want on their own.

Concept

subsidies of rebates

"measures what the true market demand of EVs is without that additional subsidies of rebates... demand may have cooled a little bit, but it's not declining substantially"

A rebate is a discount the buyer gets after purchase (or a credit that lowers the price). They’re saying these incentives can make EVs look more popular than they would be without the help.

Term

ADAS systems

"...being responsible for our ADAS systems and autonomous vehicles, I'd like to see the ability for vehicles to provide mobility and transport..."

ADAS are safety and driving-assist features in modern cars. They use sensors to help you stay in your lane, keep distance from other cars, and reduce the chance of crashes.

Concept

autonomous vehicles

"...being responsible for our ADAS systems and autonomous vehicles, I'd like to see the ability for vehicles to provide mobility and transport for those that can't drive anymore."

Autonomous vehicles are cars that can drive with little or no human input. The idea is to eventually help people who can’t drive anymore get around.

Car

2010 Lexus IS

"I'll tell you, in my 2010 Lexus IS that I had, Toyota loves to tie climate controls into the infotainment screen..."

The 2010 Lexus IS is a luxury sedan. The host mentions it because some older cars tie the screen to other systems like climate controls, which can make upgrades harder.

Car

2010 Porsche Cayenne

"...My 2010 Porsche Cayenne, well,"

The 2010 Porsche Cayenne is a luxury SUV with a lot of electronics. The host’s point is that some cars connect the infotainment area to safety systems, so replacing the stereo isn’t always straightforward.
