You Can Actually Buy Daddy Dave’s Wild Audi RS5 Drag Car for $425K

As first reported by thedrive.com, you’re not going to come across another Audi RS5 like this. It’s a full-on drag machine built for “Street Outlaws” star Daddy Dave Comstock, and now it’s up for grabs at a hefty $425,000. The deal even includes a chance to meet Dave himself and get a walkthrough of how this one-of-a-kind car works.

The car made its public debut at the SEMA Show 2022 and has been campaigned by Daddy Dave in the No Prep Kings series over the past few years. That series spun off from the TV show Street Outlaws, with races held on unprepped drag strips to mimic real street conditons. Speed Promotions & Racing, which ran the series, suddenly shut it down midway through the 2025 season.

Despite the RS5 badge, this build actually starts life as a 2009 Audi A5, fitted with an RS5-style front end and a heavily reworked chassis underneath. If the paint seems a little unusual, that’s because it’s Mazda’s Soul Red—definitely striking, but not something you’d normally see on an Audi.

Under the hood, things get even more extreme. The original 4.2-liter V8 is long gone, replaced by a custom-built 8.8-liter supercharged V8 paired with a nitrous system.

The sale also comes with a spare supercharger and a new rear housing that lets you switch the car over to a big-tire setup. There’s no Quattro all-wheel drive here either—power goes strictly to the rear wheels through a General Motors TH400 three-speed automatic, complete with a titanium bellhousing and a carbon fiber driveshaft.

For the same kind of money, you could pick up a brand-new 2027 Audi RS5 in both sedan and Avant forms. But building something like this from scratch would likely cost just as much—if not more.

And really, it’s not just about the hardware. This car’s uniqe character, plus its link to one of drag racing’s biggest personalities, is what really sets it apart.
