- ford performance built the bronco 4600 race truck to compete in the ultra4 stock class later this year.
- it unveiled the vehicle today at the king of hammers race in california, where the bronco 4400 rally trucks will be competing in the ultra4 unlimited class.
- the highly customized stock bronco 4600 will begin testing later this month and is likely to make its race debut in the baja 1000 in november.
after showing three 4400 rally class ford broncos earlier this week, ford performance is back with a 4600 race truck to battle in the ultra4 stock class. the 4400 unlimited class vehicles shown off earlier this week have extensive modifications, including a custom tubular chassis, the bronc0 4600 uses the same chassis, 2.7-liter ecoboost v-6 engine, and transmissions found in the sasquatch trim level that anyone could order from the automaker.
the 4600 bronco will be shown off at the king of the hammers event where a trio of 4400 rally broncos will be competing, but we won't see it race until sometime later this year in the ultra4 stock class, likely during the 2021 baja 1000 that’s scheduled to start on november 20, 2021. ahead of that, ford performance says it will be testing the 4600 bronco later this month.
the chassis and powertrain may be the same as what you'll find in the two-door sasquatch trim level, but the suspension has gotten a major upgrade with a high-performance off-road stability suspension (hoss) system that includes fox coilover shocks, wilwood engineering brakes, and 35-inch bfgoodrich mud-terrain km3 tires mounted to method race wheels 202 forged beadlock wheels. it’s also outfitted with triton engineering control arms, a heavy-duty howe hydraulic steering rack with cooler, and a dana advantek e-locking differential.
the automaker also tossed on the bright livery shown here to pay homage to the 1969 baja-1000 winning ford bronco. the front is meant to take inspiration from that victory but as the paint extends to the sides of the vehicle and toward the rear its meant to evoke a transition to the modern bronco.
ford says that it took what it learned from competing with the bronco r prototype in the 2019 and 2020 baja 1000 to help ford performance determine how to outfit the vehicle. the purpose of the 4600 is to be a test bed of aftermarket performance parts for the bronco. the automaker expects to see various racing teams using the platform and ford performance to fill out the ultra4 stock class.
