Nothing beats the smell of spent Sunoco fuel and the literal ground-shaking roar of forty Cup Series cars diving into Turn 1 at Bristol. But let’s be real. You aren't always at the track. Sometimes you’re stuck in the driveway finishing an oil change, or you’re hauling a camper down I-95, or maybe you’re just one of those fans who thinks the TV announcers talk way too much and you want the raw, unfiltered radio feed. If you want to listen to NASCAR live, you actually have more options today than back in the era when we all just carried battery-powered AM/FM headsets to the grandstands.
It’s complicated, though.
NASCAR doesn't just have one radio station. Depending on where the circuit is racing—whether it's an ISC-owned track like Daytona or a Speedway Motorsports venue like Charlotte—the broadcast rights flip-flop between two major networks. If you don't know the difference between MRN and PRN, you’re gonna spend the first twenty laps of the race scrolling through apps and missing the "Big One."
The Battle of the Networks: MRN vs. PRN
You’ve gotta understand the split. The Motor Racing Network (MRN) was founded by Bill France Sr. himself. They handle the bulk of the schedule, including the crown jewel, the Daytona 500. Then you have the Performance Racing Network (PRN), which covers the races at tracks owned by Speedway Motorsports (SMI).
Why does this matter? Because if you’re looking for a specific local affiliate on your car radio, you need to know which company is producing the show. MRN has a massive stable of over 500 affiliates. PRN is slightly smaller but arguably has some of the most "old school" storytelling vibes left in the sport. If you’re trying to listen to NASCAR live while driving through rural Georgia or the hills of Tennessee, you’re basically playing a game of scanning the dial until you hear that distinctive high-decibel engine hum in the background of a commentator's voice.

Honestly, the easiest way to bypass the "which station is it?" headache is the official NASCAR app. They pull both feeds into one place. You just tap the "Radio" icon at the top of the race center. It’s free. It’s reliable. But, and this is a big but, the delay can be a killer. If you’re trying to sync the radio audio with a TV broadcast to avoid the TV commentators, you’re going to be about 10 to 30 seconds out of sync. It’s frustrating.
SiriusXM: The Gold Standard for Hardcore Fans
If you’re serious about this, you probably already have SiriusXM. Channel 90 is NASCAR Radio 24/7. It is, hands down, the best way to listen to NASCAR live if you want more than just the race call. You get the pre-race build-up, the post-race "Garage Pass" shows, and during the week, you get Dave Moody yelling at callers who have terrible takes about the playoff format. It’s glorious.
The real "pro tip" for SiriusXM users isn't just the main broadcast. During Cup races, they often open up "Driver Channels."
Imagine this: You’re listening to the main MRN call on your speakers, but you’ve got your earbuds in listening to Kyle Busch’s team radio. You hear the crew chief telling him the tire fall-off is worse than expected. You hear the spotter saying "clear by two" as he slides up in front of a charging Joey Logano. You’re hearing the strategy happen in real-time before the TV cameras even pick up the move. That’s the "insider" experience.
Breaking Down the Streaming Options
Don't want to pay for satellite radio? I get it. Here is the lowdown on the digital side of things:
- The NASCAR App & NASCAR.com: As mentioned, these are free. You get the MRN/PRN feed and, interestingly, you can often access some driver scanners for free during certain promotional weekends.
- The TuneIn App: Both MRN and PRN have their own "stations" on TuneIn. This is often more stable than the NASCAR app if you’re on a shaky 5G connection.
- Local Radio Affiliates: If you’re old school, MRN has a "Station Finder" on their website. You put in your zip code and it tells you which AM or FM station in your town is carrying the race. There’s something special about listening to a race on a fuzzy AM station while sitting on a porch. It feels like 1975 in the best way possible.
What Most People Get Wrong About Race Scanners
A lot of fans think you can only use a scanner if you’re sitting in Row 20 at Talladega. Not true. While companies like Racing Electronics dominate the trackside rental market, you can actually listen to NASCAR live driver audio from your couch.

The NASCAR Scanner subscription (usually part of the "NASCAR TrackPass" or whatever branding they’re using this season) is a game-changer. It’s a few bucks a month. You get every single driver’s radio. You get the officials' channel. Listening to the race director talk to the flag stand is a fascinating peek behind the curtain. You’ll hear them debate whether to throw a caution for "debris" (which is often just a gum wrapper) versus a real mechanical failure.
However, be warned: the driver audio is uncensored. If a driver gets dumped coming off turn four, you are going to hear words that would make a sailor blush. It’s raw, it’s emotional, and it’s the most "human" part of the sport.
The Technical Reality of "Live" Audio
"Live" is a relative term in 2026.
If you are at the track with a physical radio scanner (the kind with the big orange antenna), you are hearing the audio at the speed of light. Zero delay. If you are using an app to listen to NASCAR live, you are dealing with "buffering."
The data has to go from the track to a satellite, down to a server, through a compressor, into the cellular network, and finally to your phone. This creates a "latency" of anywhere from 15 seconds to a full minute. If you’re following along on social media while listening on an app, you’ll likely see people tweeting about a wreck before you even hear the tires screech. It’s a spoiler alert you can’t turn off.
To fix this, some fans use "Delay" apps on their computers that allow them to pause the radio feed for a few seconds to perfectly match it up with the laggy video from a streaming service like YouTube TV or Hulu Live. It takes some fiddling, but once you get the timing of a gear shift to match the visual on the screen, it’s a beautiful thing.
Why Radio is Actually Better Than TV
I’ll say it: the radio guys are better.

On TV, they have the luxury of you seeing the action. On the radio, the announcers have to be your eyes. They use "spatial" descriptions. They don’t just say "there's a wreck." They say, "The 24 of William Byron gets a huge run on the backstretch, dives low, clips the apron, and hooks the 5 of Larson into the outside retaining wall!"
They paint a picture. Guys like Mike Bagley and Pete Pistone have a rhythm that matches the pace of the cars. When the pack is tight, their speaking rate speeds up. When there’s a long green-flag run, they settle into stories about the history of the track or what the drivers had for breakfast at the local diner. It’s a lost art form.
How to Get the Best Experience This Weekend
If you’re planning to listen to NASCAR live for the next race, don't wait until the engines are cranking to figure out your setup. The apps update constantly and sometimes log you out at the worst possible moment.
- Check the track owner. If it’s a track like Kansas or Darlington, go to the MRN website. If it’s Vegas or Texas, check PRN.
- Download the NASCAR app and create a free account. You don’t need the paid version just for the basic radio broadcast.
- Sync your gear. If you’re at home, try to get the audio running through a decent Bluetooth speaker. Phone speakers don't have the range to capture the low-end rumble of the engines, which is half the fun.
- Find a "Spotter" on social media. Follow accounts that post the "best of" scanner audio. Sometimes they’ll tell you which driver is having a particularly "vocal" day so you know who to tune into on the scanner.
Listening to a race is a different kind of fandom. It requires more imagination. It’s less passive than just staring at a screen. You start to recognize the different sounds of the engines—how a Ford might sound slightly different on deceleration than a Chevy, or how you can hear a missed shift before the announcers even see the car lose momentum.
Whether you're using a $500 Uniden scanner at the track or a cracked iPhone in your backyard, getting the live audio is the only way to truly feel the pulse of the race. It turns a "car race" into a three-hour soap opera at 200 miles per hour. Get your headset on, find your frequency, and settle in. The green flag is about to drop.
Actionable Next Steps
- Identify your race: Look at the upcoming NASCAR schedule and note the track. If it's an SMI track (like Atlanta, Bristol, or Charlotte), bookmark goprn.com. For most others, bookmark mrn.com.
- Test your data: Open the NASCAR app on your phone while away from Wi-Fi to ensure the audio player loads correctly on your cellular connection.
- Update your SiriusXM: If you have a car subscription, check if your plan includes "Streaming" so you can listen on your phone or smart speaker when you aren't in the driver's seat.
- Buy a headset: If you plan on listening via your phone for three hours, invest in comfortable, over-ear noise-canceling headphones to truly immerse yourself in the engine sounds.
