Muscle Cars / 2 Comments

Meet the most powerful non-OEM production Mustang you can buy.

Florida-based tuning company Steeda has unveiled its latest monster Mustang with upgraded aerodynamics and suspension, then topped off with a supercharged V8 with 825 horsepower and 640 lb-ft of torque. According to Steeda, the Q850 Streetfighter hits 60 mph in 3.2 seconds and the quarter mile in 10.23 seconds, while the rest of its upgrades give it a severe attitude and a big, extra dose of handling prowess. Also, according to Steeda, it's the most powerful non-OEM production Mustang you can buy. Steeda has built a faster Mustang, but it was something special.

"The 825 hp Steeda StreetFighter was created for one thing and one thing only - to dominate on & off the track. If you are driving a Q850 and looking for a Saleen, a Roush, or a Shelby, check your rear-view mirror because they won't be able to keep up," boasts Dario Orlando, SCCA Champion Racer & President of Steeda Autosports.

Steeda identifies aerodynamics as being the crucial layer over the top of its mechanical upgrades. The new front fascia minimizes drag while improving downforce, while the rear spoiler balances out drag and downforce. The final piece of aero comes from the lowered suspension, and it all adds up to reduce the Mustang's tendency to understeer while boosting all-around traction, lateral grip, and overall dynamics.

From there, Steeda's G-Trac Suspension System is fully adjustable for fine-tuning to purpose and conditions. The aim is for the Q850 Streetfighter to be the ultimate car for the weekend track or drag strip warrior that can be comfortably driven during the week.

Steeda's suspension upgrade goes deep and includes new sway bars and mounts, a subframe bushing and alignment kit for the subframes, a bump steer kit, camber alignment plates, and specially tuned alignment. Wrapping the Velgen VF5 Gloss Black Flowformed Wheels are a set of staggered Nitto NT555 G2 Ultra High-Performance Tires.

Under the hood, Steeda has gone to town on the 5.0-liter Ford V8 engine, starting with a substantial 3.0-liter Whipple supercharger. That's aided by a high-flow cold-air intake system, a billet oil separator, and a Steeda/Ford Severe Duty IRS Half-Shaft Upgrade. For manual versions of the Q850 Streetfighter, the stock clutch is bolstered by a Steeda Clutch Spring Assist and spring Perch Kit Upgrade.

The Q850 Streetfighter costs $34,995 plus the price of the Ford Mustang used as the base. Customers can then add options to suit the car for how it's used, ranging from brake upgrades to a roll cage with a rear-seat delete.
