About this episode

A deep dive into Horace Powertrain, a new joint venture formed from the powertrain divisions of Renault, Volvo, and Geely, focusing on next-generation engines and hybrid solutions. Tom Lewis discusses the company's strategy to innovate in small displacement, high-efficiency engines while avoiding the V8 market. The conversation touches on the evolving automotive landscape, the importance of internal combustion engines in the near future, and the challenges faced by legacy automakers in transitioning to electric vehicles. Insights into the competitive dynamics of the automotive industry and the potential for Horace to disrupt traditional powertrain operations are also explored.

Concept

powertrain

"So, we’re a new joint venture with 125 years of experience. So, essentially, we are the carve out of the powertrain divisions of Renault, Volvo, and Geely."

The powertrain is everything that moves a car: the engine, gears, and parts that get power to the wheels. It’s what makes a car go forward or backward.

Concept

small displacement engine

"We’re focused big on hybrids and high efficiency, internal combustion engines, turbocharged engines. I would say also we’re kind of more in the small displacement space."

A small displacement engine is a smaller, lighter engine that uses less fuel. It’s common in city cars and hybrids.

Term

turbocharged engine

"We’re focused big on hybrids and high efficiency, internal combustion engines, turbocharged engines."

A turbocharged engine has a small turbine that pushes extra air into the engine, so it can burn more fuel and produce more power.

Concept

Formula One

"[413.0s] That's like Formula One levels. [415.0s] Yes."

Formula One is the top level of car racing, where cars are built to be as fast and powerful as possible. People often use it as a comparison for how advanced or efficient something is.

Part

pistons

"There's been very little purchase of, I mean, yeah, everybody buys pistons, you can buy con rods, you can buy blocks, let's say."

Pistons are the round parts that move up and down inside an engine’s cylinders, helping to make the car go.

Part

blocks

"There's been very little purchase of, I mean, yeah, everybody buys pistons, you can buy con rods, you can buy blocks, let's say."

Engine blocks are the big metal boxes that hold all the engine parts together, like cylinders and pistons.

Part

con rods

"There's been very little purchase of, I mean, yeah, everybody buys pistons, you can buy con rods, you can buy blocks, let's say."

Connecting rods are metal arms that connect the pistons to the engine’s crankshaft, turning the piston's up‑and‑down motion into spinning power.

Term

Hemi

"[656.0s] Okay, we know what the Hemi, those are toys, right?"

A Hemi engine is a type of car engine that has a special shape inside the cylinder, which helps it make more power and sound unique.

Term

plug-in hybrid

"Whether horse supplied that plug in hybrid,"

A plug‑in hybrid is a car that can run on both gasoline and electric power. You can charge its battery from a wall outlet, so it can drive some miles without using gas.

Term

three and a half liter turbo V6

"or horse supplied that three and a half liter turbo V6."

A 3.5‑liter turbo V6 is a type of engine with six cylinders that uses a small turbine to make it stronger. It’s common in many modern cars for good power and efficiency.

Part

V8 engine

"[829.0s] And, you know, it's aimed with GM's V8s, Ford's V8s."

A V8 engine has eight cylinders that make it strong and powerful, often used in big cars like trucks or muscle cars.

Brand

Mercedes

"[991.0s] Yeah, Mercedes, we announced that we're providing the engine for the next generation, a class."

Mercedes-Benz is a famous German car company that makes fancy cars and trucks. They’re known for good quality and smooth driving.

Concept

extended range EVs

"[1020.0s] And one of them is extended, extended range EVs."

An extended‑range EV is a car that runs on batteries for a while, then uses a small engine to keep going if the battery runs low. It’s like having a backup power source.

Term

Bev platforms

"And so you can imagine the use case behind that is a lot of companies have made these Bev platforms."

A BEV platform is the basic design of a car that runs only on electric power, with batteries and motors built into its structure.

Concept

hybrids

"[1061.0s] And there's a, you know, an obvious pushback to hybrids."

A hybrid car uses both gasoline and electric power to run, so it can be more fuel‑efficient than a regular car.

Term

ADAS features

"[1075.0s] the infotainment features, ADAS features, all the latest and greatest tech,"

ADAS are safety features that help the driver by warning them or even taking control in certain situations, like keeping you in your lane or stopping the car if a collision is imminent.

Term

four-cylinder engine

"[1462.0s] Why did you guys avoid the three cylinder thing? [1465.0s] Because I mean, a lot of manufacturers are looking at that, reduces parts and reduces internal friction and things like that."

A four-cylinder engine is a type of car engine that has four places where fuel burns to make power. Most everyday cars use this kind of engine because it works well and isn’t too expensive.

Term

three-cylinder engine

"[1465.0s] Because I mean, a lot of manufacturers are looking at that, reduces parts and reduces internal friction and things like that. [1473.0s] Why fours instead of three?"

A three-cylinder engine has only three places where fuel burns to make power. It’s lighter and can use less gas, but it may feel a bit rougher than engines with more cylinders.

Car

Ford S-10

"[1473.0s] Why fours instead of three? [1475.0s] We've got the fours S-10, three cylinder."

The Ford S-10 is a small pickup truck made by the American company Ford. It was sold in the 1980s and 1990s and is known for being easy to drive and useful for light jobs.

Renault is a car company from France that makes many different kinds of cars, like small city cars and bigger family cars.

Term

emissions headroom

"So a lot of these engines that the domestic manufacturers in the United States have, they're sort of running out of emissions headroom."

It’s how much room a car engine has to keep pollution low while still running well.

Term

Ampere

"So, I think Ampere is the right analog to horse."

Ampere measures how much electricity is flowing, similar to how horsepower measures engine power.

Term

hybrid transmission

"I mean, that's separate from us, but I would say, you know, within a hybrid transmission."

A hybrid transmission helps a car use both gasoline and electric power, making it more fuel‑efficient.

Brand

Alfa Romeo

gear ratios

"[2032.0s] How close can you get there's a way we can tune that or change gear ratios, [2036.0s] you know, in order to meet what they need within our portfolio."

Gear ratios decide how the engine’s power is translated to the wheels. Changing them can make a car accelerate faster or reach higher speeds, depending on what you want.

Term

fuel efficiency

"You tell me the emissions and fuel efficiency that you have to hit."

Fuel efficiency tells you how many miles a car can go before it needs more fuel. Higher numbers mean the car uses less gas for the same distance.
