About this episode

BMW’s Z1 gets the full Carmudgeon treatment: a rare, non-US roadster built in small numbers as a “Zukunft” (future) tech showcase. The hosts dig into its concept-car vibe—thermoplastic/fiberglass body on a steel perimeter structure, electrically dropping doors, and a first-for-BMW multi-link rear axle. They debate whether it’s a meaningful BMW milestone or an evolutionary dead end, then compare its real-world driving: refined, composed, and surprisingly competent, but not dramatically more exciting than an E30.

Technical Too Afraid to Ask
Brand

Hagerty

"Okay. This is the Carmuggin show, which is driven by Hagerty, which explains why I have a Hagerty hoodie on."

Hagerty is a company that’s big in the classic-car world. They insure and cover collector cars, so it fits the theme of this episode.

Concept

convertible

"Warm out. We have a convertible. [102.3s] Are those things related?"

A convertible is a car with a retractable roof, typically either a fabric soft top or a power-operated hard top. Converting to open-air driving changes how the car feels and can affect structural rigidity and weather sealing.

Concept

chassis code

"It's chassis code. It's not anything different... It's a chassis code. So this is an E30."

A chassis code is basically BMW’s internal “model ID” for the car’s platform. It’s how you tell what underlying body/chassis a car is based on.

Concept

short wheelbase

"It's an E36 with E30 rear end. That's the short wheelbase. That's the hatchback."

Short wheelbase means the car is “shorter” between its front and rear wheels. That can make it feel more nimble and change how it drives.

Car

E30

"This is an E30 with an E36 for suspension. What? Yeah. Technically, it was not yet the E36 suspension because this car came out."

An E30 is a BMW 3 Series from the 1980s. It’s a popular car to modify, and here they’re talking about mixing parts from a later BMW 3 Series suspension.

Concept

Zukunft

"Z stands for Zukunft, which means future in German. So this is future one."

“Zukunft” is German for “future,” and the hosts connect it to the “Z” in BMW Z1. This is part of the car’s branding story: BMW positioned the Z1 as a forward-looking, technology-forward project.

Concept

Foschung

"BMW love, the Germans love to be like, this is the new Mercedes F400. F means Foschung, which is research. And so they all have these weird names about like,"

The transcript appears to reference “Foschung,” which is likely a mis-transcription of “Forschung,” German for “research.” The hosts are explaining the naming logic behind BMW’s “F” reference as “research,” tying it to the idea of technology showcases.

Car

BMW Z1

"So the idea behind this car was let's make a car out of thermoplastic... all of this to say the Z1 was not sold in the United States... the three sort of main things that make this car different than other BMWs of the moment were the Z-axle..."

The BMW Z1 is a special BMW roadster. It’s talked about here because it has some unusual engineering choices compared with other BMWs from the same time.

Term

thermoplastic

"So the idea behind this car was let's make a car out of thermoplastic. Is that the unifying concept?"

Thermoplastic is a plastic that you can heat up and shape, then it hardens again when it cools. In cars, it can help with weight and manufacturing.

Concept

multi-link rear axle

"So the three sort of main things that make this car different than other BMWs of the moment were the Z-axle... the first multi-link rear axle that BMW did... So this was BMW's first multi-link."

A multi-link rear axle uses multiple arms to hold the rear wheels in better control. That usually helps the car handle more predictably when you drive hard or over bumps.

Brand

Mercedes

"Yes, I was just going to say in response to whom and what?... This is now, remember, almost a decade after Mercedes did a multi-link."

Mercedes is mentioned because they used a similar multi-link rear suspension idea earlier than BMW. The hosts use it to show how suspension tech developed over time.

Term

electrically dropping doors

"This was the first time we'd ever seen electrically dropping doors from a BMW. So it may be also the last time anyone has seen it from anyone."

They mean the door opens by moving downward using a motor. It’s not a normal hinge-swing door, so it needs extra engineering to make it work safely.

Term

side sill

"And so the door goes down into the body, into the side sill, and the window goes into the door all at the same time."

The side sill is the strong lower part of the car’s side, near the floor. If the door has to drop down into the body, the sill has to be shaped to make room.

Concept

hinged door

"There are two types of car doors that work really well. There's a hinged door and then there's a sliding door."

A hinged door is the normal door that swings open on hinges. It’s common because it’s straightforward and easy to use.

Concept

sliding door

"There's a hinged door and then there's a sliding door. They both work incredibly well."

A sliding door opens by moving sideways instead of swinging. It can be helpful when parking space is tight because it doesn’t need as much swing-out room.

Car

E28 M5

"I just remember hopping into that and an E28M5 with 11,000 kilometers on it..."

The E28 M5 is an older BMW M5—an early “M” performance model. They’re saying they got into one and drove it, then kept it for a short time afterward.

Term

pop-up headlights

"If you made those pop-up headlights, you would, you could see the family resemblance..."

Pop-up headlights are headlights that slide out from the front when you turn them on. When they’re closed, the front of the car looks cleaner or different.

Concept

concept car

"It kind of, the whole thing to me, it feels like a concept car that sort of ended up in production, which is I think probably the coolest thing about the entire car."

A “concept car” is a prototype built to showcase new design ideas, technologies, or styling directions—often not intended for mass production. The speaker’s point is that the Z1’s interior/exterior styling feels like it came straight from a concept, but was actually produced.

Concept

volume

"Plastic molds for the volume. I mean, so speaking of volume, how many of these things approximately were made?"

Here “volume” means the number of cars that were produced. They’re asking how many of these BMW Z1 roadsters exist.

Concept

limited production car

"Was it in their intent to have it be a limited production car? Or would they have sold more?"

A “limited production car” is intentionally built in relatively small quantities, often to create exclusivity or to test a concept. The discussion here centers on whether BMW’s Z1 strategy was meant to cap demand, and how production numbers affected its reputation and market impact.

Concept

recession

"No, no, there was a big recession, which I think. Killed off everything. I mean, it killed off so many."

A recession is a broad economic downturn that reduces consumer spending power. In the segment, the recession is blamed for killing off “frivolous” and “premium” purchases, which affected the market success of the cars discussed.

Concept

premium segment

"Anything frivolous. Anything premium. Any of the cars that I've covered for revelations that came out in that period all were marketplace failures..."

The “premium segment” refers to higher-priced vehicles aimed at buyers willing to pay more for brand, comfort, and features. The speakers argue that during the recession, even premium cars struggled because demand softened.

Concept

marketplace failures

"Any of the cars that I've covered for revelations that came out in that period all were marketplace failures because no one had the money to buy a Chizetta, Marota."

“Marketplace failures” here means cars that didn’t sell well enough to be considered successful in the market. The speakers connect these failures to the recession and reduced demand for premium, niche, or expensive vehicles.

Concept

economic realities

"...And I think that segment of the market was largely encumbered by economic realities. Oh, the pores are revolting again."

“Economic realities” refers to the practical constraints of the economy—like job insecurity, reduced credit availability, and lower discretionary spending. The speaker uses it to explain why certain luxury cars struggled even if they were otherwise appealing.

Concept

packaging reasons

"And my understanding with the E36 compact was that it had the trailing arm suspension from an E34 packaging reasons..."

Packaging reasons means “it has to fit.” Even if a design is better, it may not be possible if there isn’t enough space in the car’s body for the parts.

Term

intake

"Yeah. The intake itself, maybe there's a K&N filter or something in there, [1097.8s] but my God, it sounds good."

The intake is how air gets into the engine. If the intake is changed, it can change how the car sounds and how it feels when you drive.

Concept

Refinement

"I think what you're going to get at next, if I had to predict where we go, is. [1109.8s] Refinement. [1111.1s] Yeah. [1111.8s] I think the defining characteristic of the car is. [1114.3s] Refinement."

Refinement is how smooth and “polished” the car feels. A refined car is usually quieter and less rough in everyday driving.

Part

instrument cluster

"...the visceralness and the overall experience of looking at this instrument cluster, which is a little bit peculiar..."

The instrument cluster is the driver-facing panel that houses gauges like the tachometer and speedometer. The speaker calls it “peculiar” because the gauge layout, sizes, fonts, and colors create a distinctive visual personality that contributes to the overall experience.

Term

snow tires

"I wonder if this would be... This particular car would be more fun if it had like snow tires on it. Right, so you could slide it around a bit,"

Snow tires are made to grip better when the road is cold or slippery. In this case, they’re suggesting the BMW Z1 would be more fun because the tires would let it slide around more easily (but still controllably).

Term

slide it around

"This particular car would be more fun if it had like snow tires on it. Right, so you could slide it around a bit, and you could overwhelm the rears,"

“Slide it around” means the car starts to lose grip and you let it rotate a bit instead of staying perfectly straight. It’s basically about how much traction the tires have.
