First look at the all-new, production-based Ultra4 Racing 4600 class Ford Bronco that was just unveiled at 2021 King of The Hammers. 

Ford Performance has revealed the all-new Bronco 4600 race trucks that will run in ULTRA4 stock class beginning this year. The all-new outdoor brand of Built Wild 4x4s, Bronco 4600 race truck demonstrates how 2021 Bronco two-door and four-door customers can prep their 4x4 for off-road racing in the ULTRA4 series.

“Innovating the off-road landscape and competing with Bronco’s higher-speed off-road abilities have always been at the core of Bronco brand’s heritage,” said Dave Rivers, Ford SUV marketing manager. “Our new Bronco 4600 race trucks underscore our motorsports heritage and how the all-new 2021 Bronco can be tuned from the showroom floor to compete in the grueling ULTRA4 stock class series.”

Like the first-generation Bronco that took the 1969 Baja 1000 outright, new Bronco 4600 builds on this winning tradition starting with a 2021 Bronco two-door SUV with stock powertrain running on a competition-tuned High-Performance Off-Road Stability Suspension (HOSS) System.

“Bronco 4600 underscores how ready the all-new Bronco is for competition and how Ford Performance is committed to driving the brand’s success across multiple off-road series,” said Mark Rushbrook, global director, Ford Performance Motorsports. “We look forward to off-road racing teams coming to this platform and to Ford Performance stepping up to continuously enhance the state of the art in off-road racing for them.”

Testing of Bronco 4600 begins later this month, with the race trucks going on to run this year in ULTRA4 alongside factory-backed Bronco 4400 series race trucks also revealed this week at King of the Hammers in Johnson Valley, California. 

Built on a 2021 Bronco two-door with Sasquatch™ Package, Bronco 4600 utilizes race-tested production 2.7-liter EcoBoost twin-turbo V6, SelectShift® 10-speed automatic and second-generation T-6 chassis. It serves as a test bed for a growing list of Ford Licensed Accessories and Ford Performance parts alongside the independent performance aftermarket.

Taking learnings from the Bronco R Race Prototype that ran the 2019 and 2020 Baja 1000, the Bronco 4600’s competition-tuned high-performance off-road stability suspension features Fox coilover shocks with remote reservoirs and Fox pneumatic bump stops at all four corners. It also features Wilwood Engineering brakes and 35-inch BFGoodrich® mud-terrain T/A® KM3 tires mounted to Method Race Wheels 202 Forged Beadlock wheels.

Heavy-duty front portal hubs from 74 Weld are mounted to Triton Engineering control arms with heavy-duty Howe hydraulic steering rack with cooler. A factory Dana™ AdvanTEK e-locking differential with RCV custom halfshafts deliver front wheel torque. In back, Triton Engineering rear links support a Dynatrac ProRock XD60® axle with an ARB 35-spline Air Locker® and Spidertrax Spider 9™ axle shafts and hubs. Ford Performance supplies modified front and rear modular steel bumpers and a Warn® ZEON® winch, while RIGID® LED off-road lights improve night vision. A custom roll cage by Geiser Brothers and first-ever FIA off-road-certified race shells from Recaro® are added inside.

Bronco 4600 series teams feature an all-star lineup of off-road racing veterans, including Fun-Haver teammates Vaughn Gittin Jr. and two-time King of the Hammers champion Loren Healy. In addition, a Bronco 4600 will be driven by teammates Jason Scherer, a three-time King of the Hammers champion and Bailey Cole, seasoned racer in ULTRA4 and Score Baja 1000 winner in class. A third Bronco 4600 race team includes Brad Lovell, who has won championships in ULTRA4, and his brother Roger Lovell, a professional engineer who has used his talents in off-road design and also has multiple off-road racing wins and championships.

Bronco 4600 race trucks feature a new livery leveraging factory 2021 Bronco colors – Race Red, Oxford White and Velocity Blue. The front design takes inspiration from the 1969 Baja 1000-winning Bronco, with matte black hood, plus white upper and red lower body lines that transitions into a more modern Bronco design scheme extending rearward.

“Our new ‘war paint’ scheme tells the Bronco race story – up front is chapter one that traces back to the victorious 1969 Bronco, then, as you travel along the side, the lines get more diagonal, more futuristic, signaling the future of the brand,” said Scott Guan, Bronco designer.

The hood sports a white Bronco logo. Like Bronco R Race Prototype and Bronco Sport Rebelle Rally trucks, Bronco 4600’s “R” in the grille is distinctly red.

Bronco brand and Ford’s collaboration with ULTRA4 signals a growing presence in the off-road enthusiast realm. Recently, Ford stepped up to serve as official truck and SUV of SCORE-International Off-Road Racing, which holds the Baja 500, Baja 1000 and San Felipe 250 championships. Ford also serves as official vehicle of Best in the Desert.
