Porsche GT Boss on the Future of NA Engines, GT Cars & the New GT3 Cabriolet
Topic

GT3 Cabriolet

The episode title includes “GT3 Cabriolet,” but this specific excerpt doesn’t talk about it directly.

Concept

naturally aspirated

A naturally aspirated engine doesn’t use a turbo or supercharger to force air in. It makes power by drawing air in normally, so the response can feel more immediate.

Concept

GT models

“GT” is Porsche’s label for their more performance-focused cars. They’re set up to feel more like a track car—tighter handling and more aggressive tuning than a regular model.

Term

GT3 RS

“RS” usually means the more track-focused, higher-performance version. A GT3 RS is Porsche’s more extreme, race-ready version of the GT3.

Term

GT4

GT4 is a racing class for cars that come from production models. It’s often considered a more approachable, less expensive step than GT3.

Term

GT2

GT2 is a higher-performance GT racing class than GT3 in many rule sets, typically with fewer restrictions and more emphasis on outright speed. Porsche’s GT2 models are built around that idea of maximum performance for the class.

911 Porsche Gt
Car

911 Porsche Gt

The Porsche 911 is Porsche’s famous sports car. In the podcast, it’s mentioned as a key part of Porsche’s future performance plans. It’s basically the model people think of when talking about Porsche’s track and driving excitement.

Dodge Ram
Car

Dodge Ram

The Dodge Ram is a big pickup truck. It’s often chosen for towing and carrying stuff, and in this case the speaker says theirs is a 2017 with a long bed and a stronger engine.

Term

souped up hemi

“Hemi” is a nickname for a specific kind of engine design that Chrysler used. “Souped up” means it’s been upgraded or tuned to feel stronger than a standard version.

Term

long bed

A “long bed” means the truck’s cargo box is longer. That makes it easier to carry bigger or longer stuff than a short-bed truck.

Term

towed

To “tow” means pulling something behind the vehicle, like a trailer. The speaker is saying they used the truck to haul bikes and other stuff.

Term

long tube headers

Headers are parts that route exhaust gases out of the engine. “Long tube” headers are a performance style that can help the engine breathe better and make more power.

Term

normally aspirated

Normally aspirated means the engine doesn’t use a turbo or supercharger. It makes power naturally by breathing through the intake and exhaust.

Term

open exhaust

Open exhaust means the exhaust is set up to be louder and flow more freely. Less muffling usually makes the engine sound more aggressive.

Nissan Gtr
Car

Nissan Gtr

“GT-R” is Nissan’s famous performance sports car. People use it like a name for the whole car, not just a description.

Term

car play

CarPlay lets you connect your iPhone to the car and use apps like maps and music on the car’s screen. The speaker is saying they care about it a lot.

Term

fake noises

Electric cars sometimes play made-up sounds so people can hear them. Some drivers don’t like those sounds because they don’t feel real.

Cayenne
Car

Cayenne

The Porsche Cayenne is Porsche’s SUV. Here, they’re talking about a small sound system on the car that makes noise so it’s not completely silent at low speeds.

Term

loudspeaker

Because electric cars can be very quiet, they often use a speaker to make a sound when you’re driving slowly. It helps other people notice the car.

Topic

Angelis Crest Highway

They’re talking about a specific scenic drive they’ll do. It’s the kind of road where you can really feel how a car handles.

Topic

Laguna Seca

Laguna Seca is a well-known race track in California. They’re saying they ended up there on a previous trip.

Term

Autobahn

The Autobahn is Germany’s highway system. People associate it with very high speeds, because some sections don’t have a general speed limit.

Concept

triple digits

“Triple digits” just means speeds above 100. Here, they’re saying they saw a lot of very fast driving during the pandemic.

991.2 GT3
Car

991.2 GT3

This is the Porsche 911 GT3 from the 991 generation’s updated version (“.2”). They mention it because they’ve driven multiple GT3 generations and are comparing how each one evolved.

Term

PDK

PDK is Porsche’s dual-clutch automatic transmission. It shifts quickly by preparing the next gear in advance, so the car feels more responsive than a normal automatic.

997 GT3 RS
Car

997 GT3 RS

This is a Porsche 911 GT3 RS from the 997 era. They’re saying it’s one of their favorite track-focused Porsches ever, which sets the bar for what they think the newer GT3 should match.

Term

anti-dive technology

Anti-dive technology is a suspension design feature intended to reduce the car’s tendency to pitch forward under braking. It typically uses geometry and/or hydraulics to limit front-end compression so braking feels more stable and predictable.

Term

torque

Torque is the “pull” the engine has—how strongly it can twist the drivetrain. More torque usually means the car feels quicker when you start moving or accelerate out of corners.

Term

emission regulations

Emission regulations are government rules that limit pollutants like NOx and hydrocarbons from the exhaust. They can force engine calibration changes (and sometimes hardware changes) that reduce output or change how power is delivered.

Term

final gear ratio

The final gear ratio is like the car’s “overall gearing.” It changes how hard the car pulls and how fast it reaches higher speeds for a given engine speed.

Term

synchronization

This is about making sure all the car’s systems “work together” smoothly. If the engine, gearing, and handling aren’t coordinated well, the car can feel no better—or even worse—than the previous version.

Concept

Pareto principle

The Pareto principle (often phrased as the “80/20 rule”) is the idea that a small portion of causes can produce a large portion of results. In tuning, it suggests that a lot of effort may be required to chase the remaining small percentage of improvement after the big gains are already achieved.

Topic

Angelus Grouse

They’re talking about a particular place/route they drove to test the cars. It’s basically where they went to feel the difference between the two 911 generations.

Term

load the front end

This means shifting the car’s weight toward the front wheels, usually by braking. When the front wheels carry more weight, they grip the road better and the car turns more easily.

Term

front grip

“Front grip” is how well the front tires stick to the road. More front grip usually means the car turns in more confidently when you start a corner.

Term

80 20 rule

This is a rule of thumb that says most results come from a small amount of effort. After that, squeezing out the final improvements takes a lot more work than you’d expect.

Term

emission laws

Emission laws are rules about how much pollution a car is allowed to produce. If the rules get stricter, car makers often have to redesign engines to meet them.

Term

linearity of the engine

Engine linearity describes how predictably engine output changes with throttle input—how smoothly and consistently the car responds as you press the pedal. The speaker is saying NA engines tend to deliver that kind of straightforward, controllable response.

Term

countermeasures

Countermeasures here means “ways to deal with the problem.” If the car gets heavier and you can’t add more power, you have to find other engineering fixes to keep it fast.

Term

performance will be gone

He’s saying that if the car gets heavier, it can feel less quick and less responsive. Without enough power to compensate, the driving performance suffers.

Term

Euro seven

Euro 7 refers to upcoming/tightened European vehicle emissions regulations that further limit exhaust pollutants. The speaker uses it as a constraint on how much power an NA engine can produce while still passing emissions requirements.

Concept

NA engines

NA means naturally aspirated—no turbo or supercharger. The speaker is discussing whether naturally aspirated engines can still make the power people want under modern rules.

Term

restrictor

A restrictor is a rule that limits how much air the engine can breathe. Less air usually means less power.

Term

emission legislation

Emission legislation is the set of rules that limits how much pollution cars are allowed to produce. Those rules can make it harder for engines to make as much power as before.

Term

four liter displacement

Engine displacement is basically the engine’s size, measured in liters. The speaker is saying that around four liters makes it easier to get strong power and torque.

Term

EPA

EPA stands for the U.S. Environmental Protection Agency, which sets and enforces emissions standards. The host is joking that they “discovered” the EPA, implying U.S. emissions rules constrain what power levels are feasible.

Term

cold start emission rules

When a car starts after sitting, it runs differently than when it’s warm. Emission rules for that moment are stricter because the engine can’t clean up exhaust as well until it heats up.

Term

bore of the piston

The bore is basically the inside diameter of the engine’s cylinder. If you change it, the engine’s shape changes, and that can affect how well fuel burns and what comes out of the exhaust.

Term

piston diameter

Piston diameter is the size of the piston that fits in the cylinder. If you make it bigger, the engine’s shape changes and that can affect how cleanly it burns fuel.

Term

pre-chamber ignition

Pre-chamber ignition is a spark system that starts combustion in a small “mini” chamber first. That makes it easier to get the main fuel-air mix burning correctly, especially when the engine is cold or operating under tough rules.

Concept

David and Goliath principle

It’s a saying that means “the underdog can still win.” Here, it’s pointing out that you don’t always need the most power to be fast—how the whole car works matters.

Brand

American makers

This just means U.S. car companies. In the discussion, they’re described as trying to win by using bigger engines and more power.

Term

synchronize the systems

It means the car’s different controls have to work together smoothly. If the engine, tires, and stability/traction systems don’t coordinate well, the car can feel slower or less predictable even if it has power.

Term

suspension

Suspension is what connects the wheels to the car and helps the tires stay planted. A good suspension setup helps the car grip the road and turn more confidently.

Term

engine management

Engine management is the car’s computer controlling how the engine runs. It adjusts things like fuel and timing so the engine makes power smoothly and doesn’t waste grip.

Term

traction

Traction is how well the tires can “grab” the road. More traction usually means you can accelerate and turn harder without spinning or sliding.

Term

loads on the car

Loads are the forces the car experiences while driving. If those forces get too high or aren’t managed well, the car can lose grip or feel unstable.

Term

steering feel

Steering feel is how “communicative” the steering is—how much feedback you get about what the tires are doing. When it feels right, it’s easier to drive precisely.

Concept

interfaces between man and machine

It means how the driver and the car “talk” to each other. If the car responds in a predictable, easy-to-understand way, the driver can push harder with more confidence.

Concept

horsepower on the straight equals and better acceleration, higher top speed

They’re saying that more engine power usually helps you go faster on straightaways. But it only works if the car can actually use the power—tires need grip and the car has to fight air resistance.

Brand

GM

GM is the company that makes Chevrolet cars. They’re giving credit to GM for how good the Corvette is.

Term

gearing

Gearing is how the car’s transmission multiplies the engine’s effort to the wheels. The goal is to keep the engine in the sweet spot so the car accelerates efficiently.

Term

9,000

Referring to “rev up to 9,000” means the engine can spin to high RPM. High-revving engines often use cam timing and intake/exhaust tuning to make power at those speeds, which matters for track acceleration and responsiveness.

Term

power band

The power band is the range of engine speeds where the car feels strong. A wide one means you don’t have to be perfectly in the right RPM to get good acceleration.

Term

wheelspin

Wheelspin is when the tires spin but the car doesn’t accelerate as much as you’d expect. It usually happens when the road is slippery or the power is too much for the grip.

Corvette
Car

Corvette

They’re comparing the Porsche GT3 to a very powerful Corvette. The message is that with enough grip and traction control, a big-power car can still put power down effectively.

Term

corner entry

Corner entry is when you first turn into a corner. If the car is stable and well-balanced at that moment, you can carry more speed through the turn.

Term

corner speed

Corner speed is your speed while going through the turn. Going faster usually makes you quicker on a lap, but only if the tires and the car’s balance can handle it.

Term

apex

The apex is the “inside” point of a corner. If you reach it well, you can set up a better exit and accelerate sooner.

Concept

Nürburgring lap time

The Nürburgring is a famous race track in Germany. A “lap time” is just how long it takes the car to go around the track once, and faster times usually mean the car is quicker on a track.

Ford Mustang GTD
Car

Ford Mustang GTD

Ford’s Mustang GTD is a special, very fast Mustang built for track performance. They’re talking about how quickly it can lap the Nürburgring and roughly how much horsepower it makes.

Corvette 01X
Car

Corvette 01X

The Corvette 01X is a special prototype Corvette used to test and prove performance. They’re using its Nürburgring lap results as a comparison point versus the Mustang GTD.

Golf Gtds
Car

Golf Gtds

The Golf is a compact car model that comes in different versions. The podcast mentions GTD versions, which are performance-leaning trims. It also notes that there can be more than one GTD type, including a competition-focused version.

Term

supercharged

A supercharger is a device that forces extra air into the engine. More air usually means more power.

Term

V8

A V8 is an engine with eight cylinders arranged in a V shape. It’s a common layout in big, powerful performance cars.

Term

rear drive

Rear drive means the back wheels get the power. That changes how the car grips and handles compared with cars that drive all four wheels.

Term

twin turbo

“Twin turbo” means the engine has two turbochargers. They compress air so the engine can make more power than it would without turbocharging.

Term

all-wheel drive

All-wheel drive means power goes to all four wheels. That usually helps the car grip the road better when you accelerate.

Term

around the ring

“The ring” means the Nürburgring race track in Germany. People use it as a benchmark because it’s challenging and well-known for lap times.

Topic

Nürburgring competition and class comparisons

They’re talking about racing at the Nürburgring and why you can’t always compare lap times directly. Different types of cars race in different categories, so the rules and performance potential aren’t the same.

Ford Gtd
Car

Ford Gtd

They mention the Ford GTD as another car that runs in a different category at the Nürburgring. The takeaway is that it’s not directly comparable to the Porsche GT3 RS because the rules and allowed equipment differ.

Term

off-the-shelf

“Off-the-shelf” means the car or parts are basically standard, store-bought items—not one-off custom race gear. The speaker is saying the GT3 RS starts from what customers can get.

Term

Camber

Camber is the tilt angle of the tire. Changing it can help the tire stay more “flat” on the road when the car is turning.

Term

tow-in

Tow-in is an alignment adjustment that changes how the tires point relative to each other. It can make the car feel more stable and change how the steering responds.

Term

pedestrian safety standard

Pedestrian safety standards are laws meant to protect people outside the car during accidents. The speaker is saying those rules can restrict design choices, which affects whether a car can be legally driven on public roads.

Term

aero parts

Aero parts are the car’s aerodynamic pieces, like wings and spoilers. They help the car grip the road at speed, but they can also be restricted by rules.

Ford Mustang
Car

Ford Mustang

They’re talking about a Ford Mustang. The point is that they’re judging the car by how fast it is on track first, before locking in the engine’s power number.

Term

lap times

Lap time is how long it takes to do one full lap on the track. They’re saying they look at lap times first to understand what the car needs, rather than just chasing a power number.

Term

full send

“Full send” just means going all-out. Here, it means the driver was pushing hard for the whole lap.

Term

turbo chargers

Turbochargers are parts that help an engine make more power. They squeeze more air into the engine, so it can burn more fuel and feel stronger—especially when you accelerate.

Term

power drive

“Power drive” here just means the car’s ability to put power down and feel strong when you accelerate. The speaker is saying the next cars should keep that kind of driving character.

Term

rear wheel drive

“Rear wheel drive” means the power goes to the back wheels. That can affect how the car launches and how it feels when you drive hard.

Concept

carbon fiber

Carbon fiber is a very light, strong material used to make parts of a car. People use it on performance cars to help reduce weight and make the car feel more responsive.

Term

greater displacement

“Displacement” is basically the engine size. “Greater displacement” means a bigger engine, which can make it easier to produce more power.

Term

differential locking

A “locked” differential helps both drive wheels work together instead of letting one spin when traction is poor. That can improve grip when you’re accelerating out of a turn.

Term

deployed technologies

“Deployed technologies” here means technologies that are actually implemented and used in the car’s systems—not just theoretical or marketing claims. The speaker is saying the newer GT3 RS uses more advanced real-world tech than the previous one.

Concept

emissions

Emissions refers to the legal limits on what a vehicle can release from its exhaust and how manufacturers must design engines and systems to meet those rules. As emissions regulations tighten, it becomes harder to extract big performance gains from naturally aspirated engines without changing the powertrain approach.

Concept

powertrain

The powertrain is the set of components that create and deliver power to the wheels—typically the engine, transmission, driveshafts, and related driveline parts. The speaker is saying they focused improvements on other areas of the car rather than changing the powertrain.

Term

aerodynamics

Aerodynamics is about how the car moves through air. The shape can create extra grip by pushing the car down, and it can also reduce air resistance so the car can go faster.

Term

active aerodynamic

Active aerodynamics means the car can change its aerodynamic “shape” while driving. That helps it create grip when you need it and reduce resistance when you’re going fast in a straight line.
