About this episode

Hosts Prior and Matt Saunders field listener letters, moving from skid-pan drifting and classic Triumph Spitfire restoration to practical garage and parking dilemmas. The conversation then turns technical: steer-by-wire’s potential for tuning steering feel, and how ADAS can intervene if you don’t hold the wheel correctly. Road-test editor notes also cover dealer and used-car inspection failures, plus track testing of extreme, aero-limited cars and the question of what counts as a proper road test.

Technical Too Afraid to Ask
Car

Toyota GR Yaris

"There is a GR Yaris just reversing up there, the good looking cars."

The Toyota GR Yaris is a small, sporty Toyota that’s designed to handle really well. People like it because it’s light and feels lively when you drive it aggressively.

Concept

skid pan

"If you can hear a car in the distance, there's a BMW on a sort of, well, it's a Bowser's skid pan, isn't it? Yes, it's not quite level, is it?"

A skid pan is a special test area where the road surface is slippery on purpose. It lets drivers practice how a car behaves when tires lose grip.

Concept

drift

"And some people are trying to drift these, and they put us, actually some of them do pretty well, aren't they?"

Drifting is when a driver intentionally makes the car slide sideways while still steering it. It’s usually done on slippery surfaces or track areas so it’s safer.

Term

understeering

"Some of them are just understeering majestically, I would say."

Understeer is when you steer into a corner but the car doesn’t turn as much as you want. It usually happens when the front tires don’t have enough grip.

Car

Triumph Spitfire

"coincidentally, I was in my garage fitting the putting the final touches to the dials of my 1969 Trump Spitfire that I'm restoring while I was listening."

The Triumph Spitfire is a classic small British sports car. A 1969 one is a popular restoration project, and people often use them for events like hill climbing.

Topic

retro dashboard modes and dial-style instrument clusters

"What do you do? Well, a quick aside on analog dials... I drove here today in the latest 911 GT3... they've just put a mode... for the digital instruments..."

They’re talking about how car dashboards can be made to feel old-school. The discussion compares dial-style gauges and retro-looking screens versus purely modern displays.

Term

analog dials

"What do you do? Well, a quick aside on analog dials. ...I quite liked it. That's good. Anyway, I like it. I like an analog looking dial..."

Analog dials are the dashboard gauges that look like traditional meters. They’re easier to read at a glance because you can quickly see where the needle or dial is pointing.

Car

Volkswagen Id

"...l, a quick aside on analog dials. I drove the new Volkswagen ID Polo GTI the other week, and that's got some very..."

The Volkswagen ID. Buzz is a van that runs on electricity instead of gasoline. It’s meant for carrying people and everyday use, but with an electric drivetrain. It often gets mentioned when talking about how EVs handle things like dashboards and controls.

Car

Volkswagen Gti

"... analog dials. I drove the new Volkswagen ID Polo GTI the other week, and that's got some very cool Mar..."

The Volkswagen Golf is a compact car that’s built for everyday driving. It’s known for being practical and comfortable for regular commuting and errands. It may be mentioned when people talk about what the dashboard and controls are like.

Term

infotainment screen

"And then on the infotainment screen in the middle, you get a little 80s cassette player for your media."

The infotainment screen is the main touchscreen in the middle of the dashboard. It’s where you control things like music and media, and here they’re describing a fun retro-style display.

Term

CRT television screen

"And you sat now in like a little kind of CRT television screen."

CRT is an old-school TV screen type. They’re saying the car’s display looks like that classic TV style, not like a modern flat panel.

Car

Porsche 911

"I drove here today in the latest 911 GT3 and that they've just put a mode, I'm sure it's new for the digital instruments, which is the old, who's it?"

The 911 GT3 is a Porsche built for track driving. In this segment, they’re talking about the dashboard gauges—how the car can show different dial-style information like oil temperature and oil pressure.

Topic

hill climb course description (U-shaped bend with a large drop)

"hill climb car. Well, it would have to be something small... The last hill climb I did... shells and Welsh... Is that the sort of, is that the effectively U shaped bend with a very large drop off of one side of it?"

The speaker describes a hill climb course feature—an effectively U-shaped bend with a large drop-off on one side—highlighting the kind of cornering and elevation changes that make hill climbs distinctive. This is treated as a driving context rather than a technical component.

Concept

hill climbing

"I guess people do a lot of hill climbing in sort of like sevens and things... I'd love the idea of a bigger aero engine special, but they're a bit too big for a hill climb, I think."

Hill climbing is a motorsport where cars race against the clock up a steep course, often on closed roads or purpose-built tracks. Because the course is short and traction matters, setups and vehicle size/weight can be very different from circuit racing.

Car

TR6

"I've always liked the idea of owning and fettling a TR6 for some reason. I don't, I've never had one. I know nothing about them."

TR6 is a classic British sports car (a Triumph). The hosts are talking about possibly owning one and tinkering with it, like a hobby project.

Car

Lotus Seven

"Maybe another catering or Lotus seven or actually even an Austin seven based special."

The Lotus Seven is a very light, simple sports car that people often modify. The hosts are using it as an example of something fun to own and tinker with.

Car

Austin Seven

"Maybe another catering or Lotus seven or actually even an Austin seven based special."

The Austin Seven is a small old British car that people sometimes use as the foundation for custom builds. The host is suggesting it as another possible project idea.

Term

steer by wire

"Tesla, apparently Toyota and now Mercedes are bringing forward steer by wire. I still want a direct mechanical link between me and the front wheels."

Steer-by-wire means the steering wheel doesn’t have a direct mechanical connection to the front wheels. Electronics interpret your input and move the wheels for you.

Car

Aston Martin DB12

"I was on, I was on a job a couple of weeks ago, [451.6s] might have been, it might have been the Aston Martin DB12s or, yeah. Anyway, I was speaking to somebody, I was speaking to sort of dynamics engineer..."

The Aston Martin DB12 is a luxury sports car. In this discussion, it’s just used as an example while they talk about a steering system that can be tuned electronically.

Car

DB2 Aston Martin Db12S

"...eeks ago, might have been, it might have been the Aston Martin DB12s or, yeah. Anyway, I was speaking to somebody, I w..."

The DB2 is an older sports car made by Aston Martin. It’s from the early days of the brand and is known for being a performance-focused car. People bring it up when talking about classic Aston Martin history.

Term

yoke

"You don't need to sort of mess about with yokes and aim for, you know, 180 degrees of, of, of steering angle from one lock to the other. [544.1s] You don't need to change the rules in any way..."

A yoke is a steering shape that looks more like a bar than a normal steering wheel. Some cars use it with electronic steering so you don’t have to turn the wheel as much, but it can feel weird if the steering response doesn’t match what you expect.

Term

steering ratio

"It was delivered to me for, I think, one of the other road testers to collect, but it was at my house, [561.3s] and I drove the bloke to the station and ran into the car twice doing it because it, [566.2s] yeah, because the steering ratio changed so greatly."

Steering ratio is basically how “quick” the steering feels—how much you turn the wheel to get the front wheels to turn. If it changes a lot, it can throw you off and make parking or low-speed driving harder.

Term

ADAS system

"You will find if you don't hold the wheel at quarter to three on this car, the ADAS system really takes a dislike to it, mate. It'll give you a sudden dab of the brakes on the motorway, check you're awake."

ADAS is the car’s “driver help” technology. It can monitor you and the road, and it may warn you or even make small corrections if it thinks you’re not paying attention.

Term

lane keeper

"Mind you, I do switch the, whatever the first two options are. It hasn't gone off yet, but maybe I've switched off the lane. Keeper says maybe that does it as well."

“Lane keeper” is the feature that helps keep you in your lane. The host is saying it might also affect when the car decides you’re not driving attentively.

Term

driving monitoring

"It's got driving monitoring. It's got lane keeping. It's got, but all the whole shooting match, mate, but I'm not sure you can turn that bit off."

Driving monitoring refers to systems that watch the driver’s behavior—often using cameras and sensors—to judge whether you’re attentive. Here it’s linked to the car’s reactions when the driver’s hands/position or attention signals don’t look right.

Term

lane keeping

"It's got driving monitoring. It's got lane keeping. It's got, but all the whole shooting match, mate, but I'm not sure you can turn that bit off."

Lane keeping is safety tech that helps keep the car from drifting out of its lane. It can nudge the steering to keep you centered.

Term

operative screen wash

"It was appalling to learn of your experience, Matthew, with supplying dealer. Let's be clear to that lack of an operative screen screen wash. What's wrong with it?"

Screen wash is the fluid-and-sprayer system that cleans your windshield. They’re saying the car they got from the dealer didn’t have that working properly.

Term

washer jets

"They cleared out the washer jets, no problem. They also checked the car over..."

Washer jets are the nozzles that spray screen-wash fluid onto the windshield. If they’re blocked, the washer system may seem like it “doesn’t work,” even though the fluid reservoir isn’t necessarily empty.

Term

sidewall damage

"...and also both of the front tires had sidewall damage, which are things that probably would have been picked up had they checked it over properly."

Sidewall damage is harm to the tire’s outer part. That area is important for strength and grip, so damaged sidewalls are a safety concern.

Term

coolant

"They also checked the car over and discovered that it had very little coolant for the engine..."

Coolant is the fluid that helps keep the engine from getting too hot. If there’s not enough of it, the engine can overheat.

Term

multi-point pre-sale check

"In this case, the multi-point pre-sale check hasn't been completed properly or at all."

It’s a dealer’s checklist they’re supposed to do before they sell a used car. The idea is to catch problems early so the buyer isn’t stuck with obvious issues right away.

Term

aerodynamic wall

"they also have this sort of aerodynamic wall that they hit around about 110, 120 miles an hour... because... they generate their performance by being small and light and having lots and lots of power... but obviously coming across a bit when there's a lot of air to move in front of them."

They mean a speed where the wind starts fighting the car so much that it feels like it won’t keep accelerating as easily. It’s basically the point where aerodynamics become the limiting factor.

Term

power to weight

"they generate their performance by being small and light and having lots and lots of power for, you know, power to weight"

Power-to-weight compares how much power the car has to how heavy it is. A lighter car with strong power can accelerate quickly even if it isn’t very slippery.

Car

BMW M2 CS

"we've had an M2, BMW M2 CS to sort of sense check it against... a conventional car with a roof... And the verdict is... it went faster than the BMW did by a long way."

The BMW M2 CS is a sporty BMW coupe they use as a comparison car. They’re basically saying the AeroLatom 4RR outperformed it by a lot on the track.

Term

coefficient of drag

"a conventional car with a roof, and, you know, probably a more sensible coefficient of drag."

Coefficient of drag is a way to measure how much the car shape pushes against the air. Lower drag helps the car keep going faster with the same power.

Car

Ariel Atom

"Which for an Atom is wild, isn't it? ... remember driving an Atom V8 and thinking this is just ridiculous. This is absurd and ridiculous."

The Ariel Atom is a very light, track-oriented car that feels raw and exciting to drive. Here, they’re saying this Atom felt incredibly quick and responsive, while still keeping that classic Atom “how it drives” character.

Term

chicane

"at the back of the circuit coming up towards the little chicane, and then when you go past the pit lane, before you brake for that chicane"

A chicane is a section of track with a quick series of turns that makes you slow down and steer more than a straight. It’s usually a tricky spot where braking and turning have to be spot-on.

Car

Mclaren P1

"Henry from Ariel was saying that around the Silverstone National Circuit, the only sort of things that are quicker are things like McLaren P1,"

The McLaren P1 is a very high-performance supercar, and it uses both gasoline and electric power. In this conversation, it’s used as a benchmark for how fast certain cars can be on track.

Car

Porsche 918 Spyder

"McLaren P1, LaFerrari and Porsche 918 Spyder. And I suspect they keep going even longer"

The Porsche 918 Spyder is a super-advanced hybrid hypercar. The hosts mention it to show how rare it is for other cars to be faster on that track.

Car

Ferrari LaFerrari

"the only sort of things that are quicker are things like McLaren P1, LaFerrari and Porsche 918 Spyder."

The Ferrari LaFerrari is a top-tier, limited-run supercar that also uses hybrid power. They mention it as one of the few cars that can be quicker than the Atom on that track section.

Term

off-camber corners

"A couple of off-camber corners here, Throgston's wide, but if you get offline on some of the off-camber ones."

An off-camber corner is a turn where the track slopes in a way that makes tire grip less consistent. The car can feel less stable, so it’s easier to lose traction if you’re not careful.

Term

downforce

"Do they make a claim for downforce because it's got a wing, hasn't it? ... balancing out the lift with the wings that they've got, which is a bit remarkable when you see the size of them"

Downforce is the “suction” effect from the car’s shape and wings that presses the tires to the ground. More downforce usually means better grip when you’re going fast.

Term

throttle travel

"It took me into my second go in it before I was prepared to put my foot all the way to the end of the throttle travel."

Throttle travel just means how far you press the gas pedal. Here, the host is saying they needed a couple of tries before they felt ready to press it all the way.

Term

lift

"And I think they've got as far as probably balancing out the lift with the wings that they've got, which is a bit remarkable when you see the size of them"

Lift is the opposite of downforce—air pressure that can make the car feel like it’s being pulled up. Wings are used to counter that so the tires keep gripping.

Concept

kit car

"Anyway, there is a solution, says Calla, which is that in our local market, there is a low cost racing series where you can race these low cost kit cars, I suppose, and take them to the track sometimes."

A kit car is a car you build yourself from a parts kit. Instead of buying a finished car, you assemble it—often with some parts you choose yourself.

Concept

build from scratch

"My dilemma, do I do the reasonable route and go ahead and buy a ready built car? Or would I be mad enough to start a project on my own... and if you start from scratch, you could get three quarters of the way through... start using it and go, no, I wish I'd done that."

“Build from scratch” here means taking on the full project—planning the spec, sourcing parts, and assembling the car—rather than buying a completed vehicle. The hosts discuss the tradeoff: more control and fun, but a higher risk of mistakes and wasted time before you’re actually driving it.

Term

chassis

"Or would I be mad enough to start a project on my own and gather parts and possibly source a chassis slash build myself and make it as my own car..."

The chassis is the car’s main frame. It’s the foundation that the rest of the parts bolt onto.

Car

Triumph Speed Triple

"Or would I be mad enough to start a project on my own and gather parts and possibly source a chassis slash build myself and make it as my own car... even had a crazy idea of one or buy a Triumph Speed Triple Engine'd one that would be a bit slower, but the sound would be something else."

The Triumph Speed Triple is a motorcycle. They’re talking about using its engine in a kit-car project, mainly to get a different sound and driving feel.

Car

Toyota Gr86

"... car. I just want to be able, you know, if it's a GR86 or a MX-5 or, you know, I want to be able to do m..."

The Toyota GR 86 is a small sports car made to be fun to drive. It’s designed to handle well and feel responsive, especially on twisty roads. People mention it when they’re comparing different affordable sports cars.

Car

Mazda MX-5

"if it's a GR86 or a MX-5 or, you know, I want to be able to do mess about with wheels and brakes and all changes and things... We've recently tested a road test at an MX-5."

The Mazda MX-5 is a small two-seat roadster that’s meant to be fun and easy to drive. The person here is talking about possibly getting one so they can work on it in their garage.

Term

boot

"And yeah, two seats in a boot, and the hood goes up and down in no time at all. Yeah. I mean, you can see why it's got one, can't you?"

“Boot” just means the trunk—where you put luggage and other stuff in the back of the car.

Term

multi-story

"Especially if you've got a park in one that's particularly busy, and you're not always sure you're going to find, you know, a space on the end of the row, or, you know, or you've got to get around a multi-story."

A multi-story car park is a parking garage with multiple levels. It can be harder to park in because the spaces and routes are tighter.

Car

Red Bull RB17

"All right. Finally, what an incredible car, says Peter Taylor. Hello, Peter. Is the new Red Bull RB17, eye-catching appearance, jaw-dropping performance,"

The Red Bull RB17 is a special Red Bull race car. The discussion is about how striking it looks and how impressive it’s supposed to be.

Concept

road legal

"why, why isn't this road legal in that case? I'm not sure if it is or it isn't, presumably it isn't, because I've had a quick look at it and it doesn't look like it could possibly be road legal."

“Road legal” means the car is allowed to be driven on public streets. If it isn’t, it may only be used for track days or special displays.

Concept

global homologation process

"presumably it isn't, because I've had a quick look at it and it doesn't look like it could possibly be road legal. So that means it hasn't been through any kind of global homologation process, presumably."

Homologation is basically the paperwork and testing a car needs to be allowed on public roads. If a car hasn’t done that process, it may not be legal to drive on the road.

Concept

hypercars

"And that's why so many of these, you know, kind of on a botanium hypercars have to be have to go into the States on what are they called? The show and display."

Hypercars are the very top tier of performance cars—fast and expensive, usually made in small numbers. They’re also harder to make street-legal because regulations are strict.

Concept

show and display

"And that's why so many of these, you know, kind of on a botanium hypercars have to be have to go into the States on what are they called? The show and display."

“Show and display” is a way some special cars can be brought into the U.S. for display purposes. It’s typically for cars that don’t meet all the normal rules for everyday driving.

Term

road test

"And whenever I see cars like this, I always think, well, if it's not been designed for road use, then it'll never be in a road test because because our requirement is, [1911.8s] we have, you know, you have to be able to drive on these cars on the road for it to be in a road test, right?"

A road test is when reviewers drive a car on normal roads to see how it feels in real life. Here, they’re saying only road-legal cars get tested because they need to be usable on public roads.

Car

2009 Ford Fiesta Ztec S

"There's still the best, the best car I've made, the 2009 Ford Fiesta Ztec S, [1996.2s] great driver's car, great road car, not bad on track, 15,000 pound, whatever it was."

The 2009 Ford Fiesta Ztec S is a small Ford hatchback that people like because it feels fun to drive. The hosts are talking about how it works well for normal roads, and it can even handle track use pretty well.

Term

five-speed box

"I remember driving it home from that and thinking, this is quite fuzzy. [2040.8s] But, because it only had a five-speed box, but it'd be nice to find a, it'd be nice to find one that felt new now..."

A “five-speed box” just means the car has five forward gears. The host thinks having more gears—or gears that are spaced differently—would make the driving feel smoother.
