Chevy Sonic Rally Car Brings LT1 Power to American Dirt Roads
GM Steps Into Rally Racing With a V8-Powered Chevy Sonic
You can find Chevrolet involved in a lot of different forms of racing, but rally racing has never been on their radar, until now. Enter this Chevy Sonic rally car, a compact hatchback packing a serious punch with Chevrolet Performance’s LT1 V8 engine under the hood and “Mello Yellow”-style livery from Days Of Thunder.
Built by PMR Motorsports in collaboration with Chevrolet Performance, this wild little Sonic is already competing in the 2025 season of the American Rally Association (ARA). Behind the wheel is veteran driver Pat Moro, who previously campaigned the same car with an LS3 V8 since 2019.
From LS3 to LT1: Upping the Game
When the partnership was announced earlier this year, Moro didn’t hide his excitement about the engine upgrade.
“I couldn’t be more excited to team up with Chevrolet Performance to bring the LT1 to American rallying,” he said. “We’ve had one of the most popular cars in the sport for years thanks to the LS3, and upgrading to the LT1 with the support of Chevrolet Performance will only take us to the next level.”
The move from the LS3 to the LT1 is a big deal. The LT1, part of GM’s Gen V small-block family, brings modern direct injection technology and improved efficiency without sacrificing the raw, naturally aspirated power fans love. For rallying, where turbocharged four-cylinder engines dominate the field, a burbling, high-revving V8 stands out immediately, both in sound and in character.
Rally Fans Love the Sonic’s Unique Edge
Moro’s LS3-powered Sonic was already a crowd favorite, thanks to its unmistakable exhaust note and the sheer novelty of a V8 rally car in a sea of smaller turbo engines. Now, with the LT1 swap, the Sonic has even more capability to match its fan appeal.
This isn’t just a marketing stunt. Moro has a long-standing relationship with Chevrolet, spanning over a decade, with appearances at the X Games and Red Bull Global Rallycross. That credibility gives the Sonic LT1 program legitimacy as it goes head-to-head in the ARA National Championship.
What’s Next for the Chevy Sonic rally car
The American Rally Association season is already underway, and fans won’t have to wait long to see the LT1-powered Sonic in action. The team is scheduled to compete in the Overmountain Rally in Tennessee on September 20–21, followed by the Lake Superior Performance Rally in Michigan on October 17–18.
With rally stages that demand agility, durability, and driver confidence, the LT1-powered Sonic will be tested in ways that few V8 cars ever are. But for Moro and Chevrolet Performance, that’s the whole point—proving the durability and excitement of GM’s small-block powerplant in one of the toughest motorsports disciplines in the world.
A New Chapter in Rallying
The Chevy Sonic LT1 is more than just a fun experiment, it’s a bold statement that American V8 power still has a place in modern motorsports. While rally racing is traditionally a playground for lightweight, turbocharged four-cylinders, Moro’s Sonic offers fans something different: raw, naturally aspirated muscle wrapped in a compact rally package.
As the 2025 season progresses, all eyes will be on how the Sonic LT1 stacks up against the competition. But one thing is certain, the sound of a V8 echoing through rally stages is something fans won’t forget anytime soon.
