Are Nascar Manual or Automatic? Know Everything about it

When you hop into a family car, you might not think much about how it changes speeds. But in the roaring world of NASCAR, how a car shifts gears is a big deal! Are Nascar Manual or Automatic? Does the driver do it, or does the car handle it independently? Let’s zoom into the world of NASCAR.

Are NASCAR Manual? 

NASCAR vehicles run on manual transmissions. This means that the person driving has to change the gears themselves. It’s a big job and needs a lot of skill. Even with the introduction of the Next Gen car, which moved the transmission and added an extra gear, making it a five-speed sequential, they haven’t adopted automatic transmissions. Interestingly, during a typical NASCAR race, drivers seldom find the need to shift gears frequently. It’s a test to the sport’s nature and the drivers’ skill level. They use a five-speed manual transaxle called the Xtrac P1334.

Why do they do it this way? Manual gears give drivers more control. Being in charge of every gear shift can make a big difference in a fast-paced race. It’s all about speed, strategy, and showing off the driver’s skills. When watching a NASCAR race, remember: those drivers are making every gear change happen!

Why Manual?

  1. Control: In those super-fast races, drivers need complete control. With manual gears, they decide exactly when to speed up or slow down.
  2. Skill: Changing gears at such high speeds isn’t easy. It shows just how skilled those NASCAR drivers are!
  3. Tradition: NASCAR has a long history. Using manual gears is a nod to the old days, keeping that classic racing spirit alive.

Manual vs. Automatic: Which Gearbox Wins?

Cars can be complicated, but here’s something simple to understand: they need to change speeds. To do this, they use gearboxes. But did you know there are two main types? Let’s find out more about them!

Manual Gearbox: The Hands-On Approach

  1. You’re in Charge! With a manual gearbox, you choose the gear using a stick shift. It gives you more control over the car.
  2. More Work, More Fun: Some people love the feel of changing gears. It’s like being part of the car’s engine. It can be more fun, especially on open roads.
  3. Saving Fuel: If used correctly, manual cars can be more fuel-efficient. It means they can save you money at the gas station!

Automatic Gearbox: Sit Back and Drive

  1. Easy Does It: With an automatic, the car does the gear-changing for you. Great for city driving where there’s a lot of stop-and-go.
  2. No Stalling: Remember how some cars stop suddenly when trying to move? That’s called stalling. It happens in manual cars if you don’t change the gears right. Automatic cars? No problem!
  3. More Modern Features: Many automatics now come with cool tech stuff. Things like adaptive cruise control work best with them.

So, Which Is Better?

There’s no correct answer! Some people love manuals for the control and fun. Others prefer automatics for the ease. It’s like picking between chocolate and vanilla. Both are great; it just depends on what you like!

History of NASCAR Transmissions

The world of NASCAR’s roaring engines and thrilling finishes is deeply rooted in tradition. The kind of transmission used is no exception.

Rise of manual transmissions

In the early days of car racing, the choice was clear – manual transmissions were the champions. Several reasons backed this:

  1. Control: Manual systems give drivers better control over their vehicles. The driver decides when to shift, allowing for strategic decisions during the race.
  2. Power: Manuals often provide more direct power from the engine to the wheels, essential for quick accelerations in races.
  3. Tradition: Racing was seen as a skill, and mastering the manual transmission was a part of that skill.
  4. Reliability: Early automatic transmissions weren’t as reliable or efficient as manuals, especially under the demanding conditions of a race.

Shift to automatic?

Technological advancements have made automatic transmissions more efficient, reliable, and intelligent. They can now shift gears at speeds a human might not be able to match. So why hasn’t NASCAR made the switch?

  1. Skill Element: Manual transmissions require significant skill, maintaining the spirit of racing as a contest of human expertise.
  2. Tradition: NASCAR has always held onto its roots. Manual transmissions are part of that history.
  3. Fan Base: Many NASCAR fans appreciate the raw skill and talent required to manage a high-speed manual transmission.

Technical Specifications

NASCAR vehicles are engineered for performance, and every component is optimized for speed, control, and reliability. The manual transmission is no exception.

Critical components of manual transmissions in NASCAR

  1. Gearbox: This isn’t your everyday gearbox. NASCAR gearboxes are built to withstand extreme conditions. Typically having 4-speed layouts, they’re tailored for high-speed racetracks.
  2. Clutch: A high-performance clutch in NASCAR vehicles ensures rapid gear shifts. It’s designed to tolerate the rapid pressing and releasing during a race, especially during crucial pit stops.
  3. Shift Lever: Made from robust materials, the shift lever is responsive to the driver’s inputs. The design ensures smooth transitions between gears.
  4. Flywheel: In racing conditions, the flywheel’s role becomes even more critical. It maintains the balance and assists in smooth gear transitions, ensuring the engine doesn’t stall during rapid shifts.
  5. Synchronizers: These are the unsung heroes. They help match the speeds of different gears during shifting, ensuring there aren’t any jarring transitions.

Advantages of manual over automatic

Why do some people still love manual cars even when automatic ones seem much easier? Well, there are some excellent reasons!

  1. Total Control:  The driver decides when to change gear with a manual. It’s like being the boss of your car’s speed and power!
  2. Fuel Efficient: Sometimes, manual cars can save more gas. That’s because the driver can control the engine better.
  3. Cost: Manual cars are often cheaper to buy and fix. Less fancy stuff inside means fewer things can go wrong.
  4. Fun Factor: Many drivers find changing gears fun! It makes driving feel like an incredible skill.

Comparison with Other Race Cars

NASCAR is unique, but how does it compare with other race cars?

  1. Formula 1: These cars are super advanced and use semi-automatic transmissions. They’re speedy but in a different way than NASCAR.
  2. Rally Cars: Used in off-road races, these cars need to handle mud, gravel, and more. They often use manual transmissions, too, but their design differs from NASCAR.
  3. IndyCars: These are more like Formula 1. They’re built for high speeds on tracks, using advanced technology and often not manual transmissions.

Formula 1 vs. NASCAR

Regarding racing, two giants stand tall: Formula 1 and NASCAR. But what makes them unique?

  • Speed vs. Stamina: Formula 1 cars are built for lightning speeds, often reaching 230 mph. NASCAR, on the other hand, is all about endurance. These stock cars might be slower, but they’re tough, often racing in close-knit packs at speeds of around 200 mph.
  • Tracks: Formula 1 races (or Grand Prix) happen on circuit tracks that can be street or purpose-built, each with unique challenges. NASCAR mainly races on oval tracks, making strategy and position vital!
  • Global vs. American: Formula 1 is a global sensation with races from Monaco to Singapore. NASCAR is deeply rooted in American culture, symbolizing the raw spirit of U.S. motorsport.

Stock car racing differences

Popularized by NASCAR, stock car racing differs vastly from other forms of racing. Here’s how:

  • Car Build: While both Formula 1 and stock car races use powerful machines, stock cars are built to resemble everyday vehicles. They’re heavier and more robust, built for close-contact racing.
  • Race Length: Stock car races tend to be longer. We’re talking about hundreds of laps requiring immense stamina from both the car and the driver.
  • Pit Strategy: Due to the race length, pit stops in stock car races are a complex dance of speed and strategy, often making or breaking a race


NASCAR races are super exciting, and a big reason is how drivers change gears in their cars! Unlike our regular cars that shift gears on their own, NASCAR drivers do it manually using a stick. This means they choose when to speed up or slow down. This choice gives them more control and shows how skilled they are. Also, when you compare NASCAR to other races, there are many differences, like the type of tracks they race on and the way their cars are built. So next time you watch a NASCAR race, remember that the drivers are shifting gears all by themselves, and that’s a big part of the fun!
