Classes realized from the Mexican 1000 could result in Ford Bronco Wildtrak Hoss 3.0 equipment

The primary query I requested Ford Bronco Automobile Engineering Supervisor Jamie Groves was, “What broke?”

“Nothing,” Groves mentioned.

Ford ran a inventory 2022 Bronco Wildtrak with the Hoss 3.0 suspension improve within the Mexican 1000 to check the SUV in excessive circumstances. The terrain ranged from on-highway transit sections to blinding silt, sand, and desert terrain that might swallow vehicles. The concept was to study what excessive Bronco house owners may endure, and to make the Bronco higher for it. Final 12 months, Ford ran a inventory 2021 Bronco Badlands that encountered its limitations. The teachings realized? There’s a necessity for Ford Efficiency’s equipment division to supply some further safety for patrons who wish to race their inventory Broncos on and off-road.

The Hoss 3.0 suspension bundle was the large information for the 2022 Bronco Wildtrak. It swapped the Hoss 2.0’s Bilstein shocks with Fox shocks which have bigger distant reservoirs and aluminum our bodies that extra effectively dissipate warmth. Ford revised the spring charges, added a brand new rear stabilizer bar and interior and outer tie rods which might be 32% stronger. Moreover, the Hoss 3.0 bundle has a steering rack utilized in the Bronco Raptor, offering a 40% acquire in most load in comparison with the usual Bronco rack.

For Bronco house owners, the manufacturing Wildtrak now has the next efficiency threshold as a result of higher shock thermals and physique movement management when optioned with the Hoss 3.0 bundle.

For Ford, the Wildtrak was a lot simpler to pilot by means of the grueling NORRA Mexican 1000 than the 2021 Badlands the staff ran final 12 months, based on Groves. The rationale was the 1.2 inches of elevated floor clearance, elevated thermal capability of the Fox shocks in order that they wouldn’t fade and lose efficiency, and a 1.9-inch wider observe for further stability. The place final 12 months the Bronco Badlands typically needed to be pushed round obstacles because of the suspension’s limitations, this 12 months there was none of that. The brand new shocks by no means skilled fade and the Hoss 3.0 suspension system was far more able to taking a soar than final 12 months’s Badland’s setup, Groves mentioned.

Ford added security upgrades resembling race seats, a roll cage, harnesses, and an additional tire together with a trolley jack. This equated to further (and unwelcomed) weight placing the Bronco at an obstacle.

The Bronco ran within the Evolution Pre-Runner Truck class in opposition to race-built pre-runners that weighed much less and had way more energy.

“We introduced a knife to a gun struggle,” Groves mentioned.

Groves famous that the five-day Mexican 1000 is totally different from the Baja 1000, because it’s a staged and timed occasion. The Baja 1000 is simply timed and also you run till you’re executed. With the Mexican 1000 every stage is a day with various distances. It’s timed, however the clock stops at evening. Throughout the day the one stops on the clock are for gasoline. The Bronco stopped so much, averaging about 100 miles per tank as a result of not having a gasoline cell. The staged setup allowed the staff to undergo the Bronco every evening and dissect its situation.

Each evening a torque audit was carried out on joints across the Bronco to make sure the bolts hadn’t moved in the course of the day (a paint pen was used to mark the location earlier than the race). The undercarriage was checked for injury as a result of floor contact, and tires had been checked.

Although nothing broke, there have been three objects that ended up needing to be addressed: tires, brakes, and a shock.

Three tires ended up springing leaks in the course of the occasion, however with the inventory built-in tire stress monitoring system the staff monitored the stress and saved driving till a driver change or refueling cease was wanted.

Each evening the entrance brake pads wanted to be modified as a result of excessive put on from the aggressive on- and off-road use. The rear pads had been solely modified as soon as in the course of the occasion. Groves famous the brake system’s nice for on- and off-road, however they merely weren’t optimized for racing
.
“Clients don’t need squealing brakes,” Groves mentioned. Anyone planning to race their Bronco will wish to improve the brake pads, Groves prompt.

Ford spokesperson Sam Schembari famous that if Ford Efficiency Elements develops efficiency brake pads they’d have the ability to de-prioritize noise and mud whereas prioritizing stopping efficiency, fade resistance, and put on.

Underbody safety was additionally a sore level. For anyone planning to race, the Wildtrak’s skid plates won’t be sufficient. Significantly, the entrance bash plate may use an improve. Groves famous the aftermarket is at present addressing this, however there’s a chance right here for Ford Efficiency equipment to step in.

However of all issues it was a rear shock that ended up being the weak spot on the SUV. At the back of the Bronco the shocks are mounted on the entrance aspect of the axle. The dampers’ distant reservoirs sit on the ahead aspect of the damper, and through an off-road stage the staff realized simply how weak these reservoirs are to wreck, particularly on the passenger aspect.

“It’s all the time the passenger (aspect), the motive force all the time protects their aspect of the truck,” Groves mentioned whereas laughing. The staff needed to nurse it again in to exchange it, and couldn’t work out what precisely occurred to the shock’s reservoir, whether or not it was a rolling rock or from being dragged on one thing.

Groves famous that aftermarket safety has already arrived to {the marketplace} for the Bilsteins, however Ford Efficiency wants to try find out how to supply safety for the brand new Hoss 3.0 Fox setup.

In a category with constructed trophy vans and pre-runners operating 40-inch tires, the inventory Bronco Wildtrak took third out of 9 rivals and arrived on the rostrum. Nothing broke and the Bronco fared significantly better than final 12 months’s Badlands, which suffered a lot higher underbody injury. It appears Ford Efficiency’s equipment division will seemingly be wanting into providing some added off-road safety bits for Bronco house owners within the close to future.
