What Engine is Cadillac Using in F1: The Inside Story of the American Power Unit

What engine is Cadillac using in F1 is a Ferrari V6 turbo hybrid, which serves as a short-term power source for their 2026 debut. This partnership provides a competitive foundation while General Motors develops its own in-house Cadillac power unit, currently targeted for a 2029 launch.

Formula 1 is changing fast. For years, only ten teams fought for glory. Now, an 11th team has joined the party. That team is Cadillac. This is a huge moment for American racing fans. It marks the return of a massive US manufacturer to the pinnacle of global motorsport. But building a competitive car is only half the battle. The real heart of the machine is the engine. Fans around the world have been asking the same question: what engine is Cadillac using in F1?

The answer is a bit of a surprise. It involves a mix of temporary partnerships and massive future plans. Right now, Cadillac is in a transition phase. They are racing today while building for tomorrow.

What Engine is Cadillac Using in F1: The Current Situation

If a person looks under the engine cover of the Cadillac car today, they will not see a motor built in Detroit. That is the honest truth. For the start of their journey, Cadillac is using a customer engine. This is a common move in Formula 1. When a new team joins, they usually buy an engine from an established builder. This lets them focus on building a fast car chassis first.

Currently, the team is using a Power Unit supplied by Ferrari. This was a strategic choice. Ferrari has some of the best technology on the grid. They have been in the sport since the very beginning. By using a Ferrari engine, Cadillac ensures they have enough speed to compete with the middle of the pack. It prevents the team from being embarrassed during their first few seasons.

However, this is just a “rebadging” deal in some ways. The engine is made in Maranello, Italy. It is then shipped to the team’s headquarters. Cadillac engineers work with Ferrari technicians to make sure it fits perfectly into the car. This partnership is vital. It gives the American team time to learn how Formula 1 works. They are learning about heat management and electronics. They are seeing how a top-tier engine behaves in different weather. This knowledge is being sent back to Michigan every single day.

The Specs of What Engine Is Cadillac Using in F1

The current engine is a piece of high-tech art. It is a 1.6-liter V6 turbo hybrid. In the world of road cars, a 1.6-liter engine sounds small. Most family sedans have bigger engines. But in F1, these motors are incredibly powerful. They produce nearly 1,000 horsepower.

The engine has several parts. There is the Internal Combustion Engine (ICE). This is the part that burns fuel. Then there is the Turbocharger. This spins at high speeds to force more air into the engine. There are also two electric motors. One captures energy from the heat of the exhaust. The other captures energy when the driver hits the brakes. All of this power is stored in a large battery.

Cadillac is using this setup to understand the limits of modern technology. They are not just driving; they are studying. Every lap provides data. This data helps the engineers understand fuel flow and energy deployment. It is a massive classroom for the American team. They need this foundation before they can build their own unit.

The 2028 Goal: A True American Power Unit

The Ferrari deal will not last forever. Cadillac has a bigger plan in mind. They want to be a “works team.” This means they want to build the whole car and the whole engine themselves. General Motors has officially registered with the FIA. They are now a registered Power Unit manufacturer.

The target date is 2028. In that year, the answer to what engine is Cadillac using in F1 will change. It will be a bespoke engine designed and built in the United States. This is a massive task. No American company has built a full Formula 1 engine in decades. It is a matter of national pride. GM wants to prove that American engineers are the best in the world.

The Michigan Technical Center

Most of the work is happening in Pontiac, Michigan. GM has a massive facility there. It is called the GM Performance and Racing Center. This is where they build engines for NASCAR and IndyCar. Now, a special section of this building is dedicated to Formula 1.

The facility is filled with the latest tools. They have specialized “dyno” rooms. These rooms allow engineers to run an engine at full speed without a car. They can simulate a lap of the Monaco Grand Prix in a basement in Michigan. This allows them to test parts until they break. They are looking for the perfect balance of power and reliability.

They are also hiring people from all over the world. They have recruited engineers from other F1 teams. They have experts from the aerospace industry. It is a melting pot of talent. They are all working toward one goal: a winning American engine.

Why Cadillac is Building Its Own Engine

Many people ask why Cadillac would spend hundreds of millions of dollars on this. The reason is simple. They want to sell cars. Formula 1 is a global marketing machine. Millions of people watch every race. If Cadillac can win in F1, it changes how people see the brand.

It is also about technology transfer. The things they learn in F1 will eventually end up in road cars. This is especially true for the hybrid system. F1 uses the most advanced batteries in the world. They are small, light, and very powerful. GM wants to use this knowledge to make better electric cars for the public.

When people ask what engine is Cadillac using in F1, GM wants the answer to represent the future of the company. They want to show that a Cadillac is not just a luxury car. It is a high-performance machine. This “win on Sunday, sell on Monday” strategy has worked for decades. It is the main reason why brands like Mercedes and Ferrari stay in the sport.

The Impact of Sustainable Fuels

One of the biggest parts of the 2028 project is the fuel. Starting in 2026, Formula 1 is moving to 100% sustainable fuels. This means the fuel is not dug out of the ground. It is made in a lab. It uses carbon captured from the air.

Cadillac is heavily involved in this research. They are working with chemical companies to create the perfect blend. The fuel must burn cleanly but still provide enough power. This is a new frontier for racing. It allows F1 to be “green” while still having loud, fast engines. For Cadillac, this is a great way to show they care about the environment. It aligns with their goal of moving toward zero-emission vehicles.

The Engineering Challenges of F1

Building an F1 engine is not like building a truck engine. The tolerances are incredibly tight. A piece of metal might expand by just a few microns when it gets hot. If the engineering is not perfect, the engine will explode.

Cadillac engineers are facing several big hurdles. The first is heat. These engines run at temperatures that would melt a normal car motor. They have to design cooling systems that are light but very effective. Every gram of weight matters. If the engine is too heavy, the car will be slow in the corners.

The second challenge is the software. Modern F1 engines are controlled by millions of lines of code. The computer decides when to use the electric motor and when to use the gas engine. It has to make thousands of calculations every second. Cadillac has to write all this software from scratch for their 2028 debut. This is often harder than building the metal parts of the engine.

The Role of the MGU-K

In the new 2026 rules, the electric power is much higher. The motor that captures energy from braking is called the MGU-K. In the 2028 Cadillac engine, this part will be very important. It will provide almost 50% of the car’s total power.

This is where GM thinks they have an advantage. They have a lot of experience with electric motors from their production cars. They know how to make them efficient. They know how to manage the heat in a battery pack. While other teams have a head start on the gas engine, Cadillac feels they can catch up on the electric side. This is a key part of their strategy to beat the established European teams.

The Political Battle to Join the Grid

It was not easy for Cadillac to get into F1. For a long time, the other teams did not want them. They were worried about splitting the prize money. They also questioned if Cadillac was serious about being a manufacturer.

The decision to build their own engine was the turning point. When GM announced they were building a Power Unit, the FIA had to listen. It showed that Cadillac was not just looking for a sticker on a car. They were bringing new technology and new investment to the sport.

This political victory was huge for Michael Andretti and the Cadillac team. It proved that they belonged at the top table. Now, the pressure is on. They have to show that they can compete. The world is watching. Every race is a test of their reputation.

Building a Team Culture

Beyond the engine, Cadillac is building a team. They have a base in the UK near the Silverstone circuit. This is where the mechanics and aero experts work. They also have the main HQ in the US. Managing people across the ocean is difficult.

They are trying to create a “one team” culture. They want the American spirit of innovation to mix with the European experience of F1. This blend is what makes the project unique. It is not just an American team; it is a global team with an American heart. They are learning to speak the language of F1 while keeping their own identity.

What the Fans Can Expect in the Coming Years

The next few seasons will be a wild ride. Fans will see Cadillac grow from a newcomer to a serious threat. The Ferrari-powered years will be about learning. There will be mistakes. There might be some broken engines. But there will also be moments of brilliance.

By the time 2028 arrives, the excitement will be at an all-time high. That will be the true test. When that American-made engine starts up for the first time in a race, it will be a historic moment. People will finally have a clear answer to what engine is Cadillac using in F1. It will be an engine that represents the best of Detroit and the future of racing.

The Legacy of the Project

Win or lose, this project will leave a legacy. It has already inspired a new generation of American engineers. It has brought more attention to F1 in the US than ever before. Cadillac is showing that it is okay to take big risks.

If they can win a race, it will be one of the greatest stories in sports history. If they can win a championship, it will change the sport forever. Cadillac is not just another team. They are a symbol of a new era for Formula 1. An era that is more global, more sustainable, and more competitive.
