Mopar SEMA 2025: The Dude Ram 1500 and SIXPACK Charger Street Machine Concepts Debut
Mopar brought serious street machine energy to SEMA 2025, unveiling two concept vehicles that showcase opposite ends of the performance spectrum: The Dude, a HEMI-powered Ram 1500 channeling early-1970s sport truck vibes in Sublime Green, and the Moparized Dodge SIXPACK Charger, a 550-horsepower modern muscle car dripping in carbon fiber and custom upgrades.
Both concepts demonstrate Mopar’s capabilities for enthusiasts wanting to personalize their rides beyond factory specifications, featuring genuine Mopar performance parts and accessories rather than generic aftermarket components.
Mopar unveils two street machine concepts at SEMA 2025: The Dude concept is a custom-built, HEMI®-powered Ram 1500 inspired by the original Dude sport trim package from the early 1970s and the Moparized Dodge SIXPACK Charger concept showcases numerous exterior and performance accessories for the all-new, modern-day, muscle car
The Dude Ram 1500: Sublime Green Nostalgia Meets Modern Performance
The Dude concept revives a forgotten chapter of truck history. In the early 1970s, Dodge offered a “Dude” sport trim package responding to the emerging sporty truck trend—utility vehicles with unique style and personality. Mopar resurrects that spirit with a modern Ram 1500 Big Horn as the foundation.
The exterior is impossible to miss: Sublime Green paint (a legendary Mopar color from the muscle car era) contrasted with satin black vintage-style C-stripes running the truck’s full length. Black accents cover the custom performance hood with side stripes and scoop bezel, lower front grille and surround, roof, mirrors, and tailgate featuring Ram-branded graphics.
The Dude rides aggressively low on satin black 22-by-10-inch wheels. A custom front splitter and side sills emphasize the dropped stance, while side-exit exhausts with black tips empty ahead of the rear wheels on both sides—pure performance truck theater.
Power comes from the iconic 5.7-liter HEMI V-8 making 395 horsepower, upgraded with a Mopar cold-air intake for improved breathing and throttle response. It’s not trying to be a desert runner or rock crawler—this is pavement-focused attitude.
Inside, the color contrast continues with Alea leather seats (front and rear) featuring bright green stitching against dark door trim. A custom instrument panel badge displays The Dude logo in bright green. Practical additions include an in-console safe for valuables, multi-accessory instrument panel rail, and all-weather floor mats.
The Dude won’t appeal to everyone—Sublime Green is polarizing, and the lowered stance sacrifices the utility that makes trucks practical. But for enthusiasts who remember the original Dude or just want something different from standard Ram offerings, it’s refreshingly bold.
The second concept takes the already-aggressive 2026 Dodge Charger and amplifies everything. Based on the SIXPACK trim with its 550-horsepower 3.0-liter Twin Turbo SIXPACK HO engine, Mopar added extensive performance and visual upgrades.
The Stryker Purple exterior gets satin carbon-fiber accents throughout. Lightweight carbon-fiber components—including hood, front splitter, and rear decklid spoiler—enhance airflow and downforce for legitimate aerodynamic benefits beyond just looking aggressive. Concept vented fenders release air pressure from wheel wells, further improving aero efficiency.
Satin Black Mopar ‘strobe’-style bodyside graphics run door-to-quarter-panel length. A performance suspension spring kit lowers ride height one inch, reducing center of gravity for improved road feel, sharper cornering, and enhanced high-speed stability.
Custom five-spoke 21-by-11-inch Brass Monkey wheels stand out visually, paired with custom orange Brembo brake calipers front and rear. The color combination—purple body, carbon fiber trim, brass wheels, orange calipers—sounds chaotic on paper but works together surprisingly well.
Performance upgrades include custom Mopar cold-air intake and cat-back stainless-steel dual exhaust system, allowing the 550-hp engine to breathe more freely. Whether these mods add significant power over stock remains unspecified, but they certainly enhance sound and throttle response.
Inside, Katzkin premium leather seats feature contrasting Tuscany Ink (black) and Palomino (tan) surfaces with orange and purple stitching echoing exterior colors. Mopar pedal covers, all-weather floor mats, and rear cargo mat complete the interior upgrades.

NHRA Stars and Sweepstakes

What These Concepts Actually Mean
SEMA concepts serve multiple purposes beyond showcasing wild builds. They demonstrate parts availability—most components on The Dude and Moparized Charger are actual Mopar products customers can purchase and install on their own vehicles.
They also gauge market interest. If certain styling elements or upgrade packages generate strong reactions, Mopar can develop them into dealer-installed option packages or direct-sale kits through their e-store.
The Dude’s nostalgic throwback approach tests whether modern truck buyers care about sport truck heritage from 50+ years ago. The Moparized Charger demonstrates how far owners can push the already-aggressive new Charger with bolt-on upgrades.
Neither concept will reach production as shown, but individual components and styling themes could influence future Mopar offerings. That’s the real value of SEMA presence—testing ideas, generating enthusiasm, and showing enthusiasts that Mopar understands their desire to personalize vehicles beyond factory specifications.
