Steeda Unleashes the 2025 Q850 StreetFighter: The Ultimate Performance Mustang

POMPANO BEACH, FL – Steeda Performance Vehicles proudly announces the official unveiling of the 2025 Steeda Q850 StreetFighter—the most advanced performance Mustang ever developed by Steeda. This supercharged powerhouse is the culmination of over 37 years of dedicated Mustang performance innovation, setting a new benchmark for performance enthusiasts.

The Ultimate Expression of Mustang Performance

Engineered for the most demanding drivers, the Q850 StreetFighter is built to dominate both road and track. It stands as a testament to Steeda’s relentless pursuit of excellence, validated through extensive development and real-world testing at Sebring International Raceway and the Nürburgring Nordschleife— a distinction no other aftermarket manufacturer can claim.

The 2025 Steeda Q850 StreetFighter is not just another Mustang—it’s the embodiment of nearly four decades of continuous refinement, delivering an unparalleled driving experience for those who accept nothing less than the best.

Unmatched Power & Performance

At the heart of the 2025 Steeda Q850 StreetFighter is a Whipple supercharged 5.0L Coyote V8, delivering an earth-shaking 810 horsepower and 640 lb-ft of torque. However, raw power means nothing without a properly engineered suspension system to harness it—this is where Steeda’s expertise truly shines.

A Revolutionary Suspension & Chassis System

The Q850 StreetFighter features the all-new Steeda G-Trac Fully Adjustable Suspension/Chassis Package, a comprehensive engineering marvel designed to redefine precision handling and maximize power delivery to the pavement. During rigorous, like-for-like testing at Sebring International Raceway with naturally aspirated Mustangs, this suspension system proved to be 7 seconds per lap faster than a comparable stock Mustang.

Unlike conventional suspension upgrades, this complete performance system optimizes every aspect of chassis dynamics, ensuring superior handling, control, and driver confidence.
