Great cars undone by one fatal flaw #319
Place

belfast

Belfast is a city in Northern Ireland. In this part of the episode, it’s where the host traveled and where the car story is happening.

Delorean DMC-12
Car

Delorean DMC-12

This is a DeLorean from 1981—the famous sports car with the “gull wing” doors. People love it for its looks and vibe, but older cars like this can be expensive or annoying to keep running.

Term

engine bay

The engine bay is the space under the hood where the engine sits. The host is saying that when lots of cars have the hood open, people tend to crowd around to look and see if there’s a problem to fix.

Concept

self-selecting group

A self-selecting group means the participants weren’t chosen at random—they chose to be there. In this case, it suggests the DeLorean owners who attended were probably the ones who take care of their cars, which can make the cars seem more reliable than average.

Term

alternator

The alternator is what keeps the car’s battery charged while the engine is running. If it can’t keep up with the car’s electrical needs, the battery can run down and the car won’t restart.

Term

central locking modules

Central locking modules are the electronics that control whether the doors lock and unlock. If they fail, the car’s locking can act up—like not unlocking or getting stuck.

Term

front suspension weaknesses

“Front suspension weaknesses” refers to known durability or design problems in the front-end suspension components. Even if the car is otherwise improved, weak suspension design can lead to handling issues, accelerated wear, or repeated repairs.

Concept

Back to the Future conversions

They’re talking about turning a DeLorean into a real-life version of the movie car. The issue is that the modifications can make the car run hotter, because the changes affect the engine area and cooling.

Term

flux capacitor

The flux capacitor is a made-up part from the Back to the Future movies. Here, they’re joking about people trying to build a real version of it for their converted cars.

Term

overheating issues

Overheating means the engine is getting too hot. The hosts say the movie-car conversions can cause that by interfering with how the car cools itself.

Term

200 kilos in weight

They’re saying the conversion adds a lot of extra weight—around 200 kg. More weight can make the car harder to drive and can also make it less aerodynamic, leading to more wind noise.

Term

aerodynamically effective

This means how well the car’s shape (and any added parts) cuts through the air. If it’s not effective, you can get more drag and more wind noise, especially on the highway.

Concept

double production in october 1981

They’re saying the company tried to make way more cars very quickly in October 1981. Ramping up production too fast can cause problems like quality issues and financial strain.

Concept

ramped up production

Ramping up production means increasing output quickly, often to meet demand or recover from delays. In this segment, the company increases production into winter when selling sports cars is harder, contributing to cash problems.

Concept

liquidators

Liquidators are people brought in when a company is in trouble to shut it down and sell off what it owns. Here, they’re described as trying to salvage the situation instead of just closing everything immediately.

Concept

receivers

Receivers are appointed to take over a struggling company so creditors are protected. In this story, they didn’t want to shut the company down right away, so they looked for a way to keep it going.

Tr7S
Car

Tr7S

The Triumph TR7 is a sports car from the late 1970s made by Triumph. In this story, the company was trying to switch production to TR7s to keep the factory running.

Honda engine
Car

Honda engine

They were talking about putting an engine from Honda into the car instead of the engine it was originally going to use. The idea was to improve the car by changing the powerplant.

Term

PRV

PRV refers to a specific V6 engine design used by multiple European brands. Here it’s mentioned because the plan was to replace that engine with a Honda one.

Person

John DeLorean

John DeLorean was the person who created the DeLorean car project. The episode says his arrest hurt the company so badly that it couldn’t recover.

Lotus Esprit
Car

Lotus Esprit

The Lotus Esprit is a sports car from Lotus. Here it’s used as a comparison point because its front suspension is set up in a way that helps the car handle more smoothly when you drive aggressively.

Term

double front wishbone

A “double wishbone” suspension uses two arms at each wheel to guide how the wheel moves. That usually makes the car feel more stable and predictable, especially when turning or braking hard.

Term

bump steer

Bump steer is when hitting a bump makes the car’s steering “fight back” or change direction by itself. It’s usually a sign the suspension geometry isn’t controlling the wheel path well.

Term

brake steer

Brake steer is when the car wants to turn or pull to one side when you press the brakes. Instead of going straight, the suspension and forces make it steer unintentionally.

Person

Colin Chapman

Colin Chapman was an important engineer behind Lotus. Here, he’s brought up because Lotus helped with the car’s design direction, and the host suggests that involvement connects to how the project ultimately went wrong.

Concept

ERM basically a plastic chassis

They’re talking about an early design idea where the car’s main structure was planned to be made from plastic. The host’s point is that this kind of chassis concept can affect how strong the car is and how well it handles.

Term

anti-corrosion warranty

An anti-corrosion warranty is a guarantee that the company will cover rust problems for a certain number of years. The point here is that even though the DeLorean looked rust-resistant, it didn’t include a long rust-coverage promise.

Term

emissions stuff

“Emissions stuff” means the parts and settings added to meet pollution rules. The hosts say that in the US, those changes made the DeLorean slower and less able to compete.

Term

stainless body

A stainless-steel body is a bodywork choice that resists rust and can be a marketing “signature” feature. The hosts argue it was both the DeLorean’s biggest selling point and a weakness because it added mass that the underpowered engine had to move.

Term

steel chassis with a fiberglass tub

They’re describing how the DeLorean’s structure was built from different materials. A steel frame was combined with a fiberglass tub, and the point is that the real finished car ended up heavier than the early plans predicted.

Term

stainless steel DeLorean bits

They mean replacement parts made from the DeLorean’s special stainless-steel body material. If you crash one, you want the right kind of panel so the car looks and fits correctly.

Term

left front wing

A left front wing is the metal panel over the front wheel on the driver’s side. They’re talking about whether you can replace that panel after damage.

Term

parts cars

A parts car is a wrecked or non-running car that people buy just to take usable parts off it. They’re saying that used to be the main way to get some DeLorean body panels.

Concept

company having gone bust halfway through production

Going bust halfway through production means the manufacturer stopped before completing the full planned run, leaving a limited supply of original parts. In the DeLorean’s case, the hosts argue that leftover production parts made it easier to support the next batch of cars, improving long-term serviceability compared with other niche classics.

Renault 5 turbo
Car

Renault 5 turbo

The Renault 5 Turbo is a turbocharged version of the Renault 5. They bring it up only to compare parts availability—basically saying some older cars are much harder to get parts for than the DeLorean.

Term

running gear

Running gear is the mechanical stuff under the car that helps it move and handle—like parts in the suspension and drivetrain. They’re saying those parts were similar to other European cars, so replacements are easier to source.

Term

cross-referenced

Cross-referenced means parts can be matched to other cars—like using the same part number or the same design. They’re saying that helps you find DeLorean parts because other European cars used similar components.

Mazda Rx8
Car

Mazda Rx8

The Mazda RX-8 is a sports car made by Mazda. It’s known for using a rotary engine, which is a different type of engine than most cars use. The podcast mentions it because the host really likes them and has driven some.

Term

rotary engine

A rotary engine is a type of engine that spins to make power instead of using pistons. In this discussion, the host says that design can make less low-end pulling power and can be harder on internal seals, especially if the car isn’t maintained perfectly.

Term

torque

Torque is the engine’s pulling force—how strongly it can get the car moving, especially at lower speeds. The host’s point is that the RX-8 didn’t have enough of that “pull,” even though it could feel smooth at high revs.

Nissan 350
Car

Nissan 350

The Nissan 350Z is a sports car made by Nissan. It’s known for being fun to drive and is popular with car enthusiasts. The podcast mentions it along with another similar model as an example of a good, well-regarded sports car.

Term

apex seals

Apex seals are small sealing parts inside a rotary engine that help keep pressure where it belongs. The host says these seals can wear out quickly, which can seriously damage the engine and ruin the car’s reliability.

Term

twin turbo

“Twin turbo” means the engine has two turbochargers. They cram more air into the engine so it can make more power.

Term

V6

A V6 is an engine with six cylinders arranged in a V shape. In this discussion, it’s the smaller engine people didn’t expect.

Term

24 valve

“24 valve” indicates the engine has 24 valves total, typically meaning four valves per cylinder on a V6 (since 6 cylinders × 4 valves = 24). More valves can allow better airflow and tuning for power and efficiency.

Term

push rod

A pushrod engine is a type of engine where a camshaft uses rods to open the valves. The host is saying the design originally came from a different engine style before being adapted.

Term

V12

A V12 is an engine with twelve cylinders. The host says people were expecting a V12 because it would have sounded and felt more special than the smaller engine that arrived.

Term

turbocharged v6

A turbocharged V6 is a V-shaped 6-cylinder engine that uses a turbo to add extra air. That usually helps it make more power from a smaller engine, but some people think it sounds worse than a bigger naturally aspirated engine.

Ferrari F40
Car

Ferrari F40

The Ferrari F40 is a famous older supercar from Ferrari. It’s known for being a stripped-down, performance-first kind of car. The episode mentions it as a point of comparison for how light or focused other cars are.

Mclaren F1
Car

Mclaren F1

The McLaren F1 is a very expensive, very fast supercar. People talk about it because it was designed to be light and quick. In the episode, it’s brought up in a comparison about how light different cars feel.

Term

four-wheel drive

Four-wheel drive means the car can send power to all four wheels. That helps it grip better on wet or slippery roads. The host is saying older 4WD systems might have been clunky or heavy compared with today’s.

Bmw I8
Car

Bmw I8

The BMW i8 is BMW’s hybrid supercar-style car. It uses a small 3-cylinder engine, and some people thought that was too small for a “real” supercar. The host argues that criticism was a big reason it didn’t get the love it deserved, even though they personally enjoyed it.

Term

three cylinder 1500 cc engine

This means the engine is a small 1.5-liter with three cylinders. The host is pointing out that some people dismissed it because it’s not a huge engine, even though the car still worked well in real life.

Term

curated

Here, “curated” means the car’s sound is intentionally designed. Instead of just sounding however the engine naturally sounds, the car is set up to make the sound feel a certain way.

Term

headers

Headers are special exhaust pipes that collect the engine’s exhaust gases and send them down the exhaust system. Because they’re shaped a certain way, they can change the sound you hear and how the exhaust flows.

Ferrari 296 GTB
Car

Ferrari 296 GTB

The Ferrari 296 GTB is a high-end Ferrari supercar that uses a hybrid setup (gas plus electric). The discussion uses it to show that even when a car is technically impressive, buyers don’t always want the same thing.

Term

downsized engine

A downsized engine means the engine is physically smaller than you’d expect. The idea is to get good power while using less fuel, but the host thinks it can feel like it doesn’t match the car’s personality.

Term

battery packs

In an electric car, the battery pack is the main battery. The worry is that it can wear out over the years, which can reduce range and make the car feel less healthy.

BMW i3s
Car

BMW i3s

The BMW i3s is an electric car from BMW. The “s” version is meant to feel more sporty than the regular i3. The podcast mentions that i3s owners have reported problems, so it’s being discussed with some caution.

Lancia Gamma
Car

Lancia Gamma

The Lancia Gamma is a car model made by Lancia. In the episode, it’s mentioned because the speaker is talking about a serious problem that could affect ownership. The point is to decide whether that issue is a deal-breaker.

Term

flat four

A flat-four is an engine where the cylinders sit opposite each other in a sideways layout. The host is pointing to this engine type as part of why the Lancia Gamma might have a serious problem.

Term

interference engine

An interference engine is built so the pistons and valves can overlap in timing. If timing goes wrong, they can hit each other and the engine can be ruined.

Term

cam belt

A cam belt times the engine so the valves and pistons move in sync. If the belt breaks, the engine can get badly damaged because the pistons and valves can collide.

Term

power steering pump

The power steering pump uses fluid pressure to make steering easier. If it’s driven in a way that’s linked to the engine’s timing, steering-related loads can trigger serious engine damage.

Term

timing chain

A timing chain keeps the engine’s timing synchronized. If it jumps a tooth, the valves open at the wrong time and the engine can be severely damaged.

Term

robotized manual paddle shift gearbox

This is basically a manual transmission, but the car automatically does the clutch and shifting for you. Older versions can be jerky or slow compared with newer automatic systems.

Lamborghini Aventador
Car

Lamborghini Aventador

The Lamborghini Aventador is a very high-end supercar. Here, the host is talking about how its automated manual transmission with paddle shifters can feel slower and less smooth than newer dual-clutch automatics.

Term

DCT

DCT means dual-clutch transmission. It can shift quickly because it’s readying the next gear before you need it.

Term

downshift

A downshift is when the car changes into a lower gear. It usually happens when you want more pull or stronger slowing, but in this case the hosts say it can take too long.

Term

throttle

The throttle is the pedal that controls how much power the engine is allowed to make. Here they’re saying the timing of easing off it can help the gearbox shift better.

Term

upshift

An upshift is when the car changes into a higher gear. They’re saying the way you lift off the gas can help the car shift more smoothly.

BMW M3
Car

BMW M3

BMW M3 CSL is a more hardcore, lighter version of the BMW M3 from the early 2000s. They’re using it as an example of how even a great transmission can still feel worse than a manual.

BMW E46
Car

BMW E46

CSL is BMW’s name for a lighter, more track-focused version of the M3. They mention it while talking about how the transmission doesn’t feel as good as a manual.

Aston Martin Vanquish
Car

Aston Martin Vanquish

The Aston Martin Vanquish is a luxury performance car with a big V12 engine. The hosts describe a frustrating early behavior where the car would protect itself by going into neutral, leaving the driver waiting at traffic lights.

Term

clutch

The clutch is what lets the car smoothly connect and disconnect the engine from the gearbox. They’re describing a situation where the clutch got too hot and the car switched itself to neutral to protect it.

Term

neutral

Neutral is when the car isn’t in any gear, so it won’t pull forward. The hosts say the car would put itself in neutral unexpectedly.

Lexus Lfa
Car

Lexus Lfa

The Lexus LFA is a special high-performance Lexus supercar with a very exciting engine. The point here is that automated shifting can feel less engaging, but the host says their LFA experience was mostly on racetracks.

Place

Valolunga

Vallelunga is a race track in Italy. The host is using it as an example of a specific corner where shifting at the wrong time can make the car feel unstable.

Term

Corsa

Corsa is a “sport” mode on some Lamborghinis. It makes the car react more sharply, and in this story it made the car feel like it got unstable when shifting mid-corner.

Lotus Evora
Car

Lotus Evora

The Lotus Evora is a mid-engine sports car that’s notable here for how its gearbox choice affects drivability. The host explains Lotus used a Toyota-sourced diesel gearbox to match a V6 that came from the Camry, and early versions ended up with very long, awkward ratios and a shift feel that could be “woolly.”

Toyota Camry
Car

Toyota Camry

The Toyota Camry is mentioned because the early Lotus Evora used an engine that traces back to it. Even if it wasn’t built to be a “sports” engine, it can still be made to work in a sports car.

Term

naturally aspirated

Naturally aspirated means the engine doesn’t use a turbo or supercharger to force air in. The host is saying that with this kind of engine, the gearbox ratios matter a lot for keeping the engine in its useful power range.

Term

self-centering

Self-centering is when a manual gear shifter naturally springs back toward the middle/neutral after you move it. If it doesn’t self-center, it can feel confusing and vague about what gear position you’re in.

Term

diesel gearbox

This means the transmission was originally built for a diesel engine. The host is saying the Evora ended up using that type of gearbox with a gasoline V6, and the mismatch in how it was fitted helped cause problems.

Term

custom bell housing

A bell housing is the housing that connects an engine to a transmission. A custom bell housing here matters because the host links it to how the gearbox had to be mounted for the Evora’s transverse mid-engine layout, which then contributed to a low-RPM rattle.

Term

shift quality

Shift quality is how good the gear changes feel. The host is saying later Evora gearboxes shift more smoothly and precisely than the early ones.

Lotus Amira
Car

Lotus Amira

The Lotus Emira is a newer sports car from Lotus. It uses a gearbox design that’s shared with another model, but the Emira’s version is described as being engineered to work better. The podcast mentions it mainly in terms of how the transmission feels and performs.

Term

bell housing rattle

This is a rattling noise coming from where the engine and gearbox connect. The host says later Evora versions fixed most of the shift feel, but the rattle never fully disappeared.

Term

ratios

Gear ratios are how the gearbox translates engine speed into car speed. Changing the ratios can make the car feel more responsive and can also help fix drivability or durability problems.

Term

close ratio editions fourth and fifth

Close ratio means the gears are set up so the RPM stays closer to the sweet spot when you shift. The host is saying that on some early Evora versions, 4th and 5th gear could fail badly, costing a lot to fix.

Term

launching fourth and fifth

Here “launching” means the transmission can lose the gear—like 4th or 5th gear not staying properly engaged. The host is saying that happened enough to worry them and lead to a big repair bill.

Aston Martin V12 Vantage S
Car

Aston Martin V12 Vantage S

The Aston Martin V12 Vantage S is a powerful sports car with a V12 engine. In this segment, the host says the manual gearbox version didn’t feel right—shifts were sloppy—so it didn’t live up to what you’d expect from the car.

Jaguar F type
Car

Jaguar F type

The Jaguar F-Type is a sports car meant to feel exciting to drive. Here, the host says the manual gearbox in this version doesn’t work well—shifts feel slow and sloppy—so it ruins the experience a bit.

Term

slushy sluggish

“Slushy” and “sluggish” are ways to describe a gearbox that doesn’t feel crisp. The host means the shifts don’t feel sharp or quick, so driving feels less fun and less controlled.

Aston Martin V8 Vantage
Car

Aston Martin V8 Vantage

The Aston Martin V8 Vantage is a sports car from Aston Martin with a V8 engine. Some versions can be had with a manual transmission. The episode brings it up mainly because it’s comparing which Vantage models were available with manuals.

Term

seven speed auto

A “seven-speed auto” is an automatic transmission that has seven gear ratios. Here, the host is comparing the car’s original automatic to the later manual version and saying the manual didn’t turn out better.

Term

slush box

“Slush box” is a nickname for an automatic transmission that feels slow to react and not very sporty. The host is basically saying some older Mercedes automatics were like that on purpose—or at least that’s what people liked about them.

Ferrari 458 Spyder
Car

Ferrari 458 Spyder

The Ferrari 458 Spyder is a mid-engine Ferrari convertible meant to feel sharp and connected. The host says the car’s body flexes on rough roads, so it can feel like it’s shaking and the steering doesn’t feel as precise.

Term

carbon monocoque

A carbon monocoque is the car’s main body made from stiff carbon-fiber. It helps the car stay rigid even when you remove the roof for a convertible.

Ford Flex
Car

Ford Flex

The Ford Flex is a family car with a very unusual, boxy shape. The episode talks about what would happen if you turned it into a convertible, and how removing the roof structure can make the car feel less stiff. It’s mentioned to explain that the roof helps keep the car rigid.
