Last week, Ford finally broke the silence about the all-new Bronco, confirming that the rugged off-roader will debut in spring 2020. This will be the first time the Bronco has been in production since 1996. After numerous leaks, another new enticing detail about the rugged off-roader has possibly been uncovered.

A user on the Bronco 6G Forum posted a union agreement document revealing changes to Ford's stamping operations. In the document, the Bronco is listed under Dearborn Stamping and Dearborn Diversified Manufacturing, the same plant that handles the aluminum body for the Ford F-150, as well as stampings for the Ford Expedition, Lincoln Navigator, and all new Ford Super Duty trucks.

This suggests the Ford Bronco will feature an aluminum body for the first time, which will make it ultra-lightweight and prevent it from rusting like older models.

As one forum user points out, the lighter material will also make it easier to remove the doors and roof panels, which will be possible according to recent patent filings. It isn't clear, however, if the entire body will be made of aluminum. Ford may only make certain components out of the lightweight material to keep costs down and make the SUV easier to maintain.

Ford remains tight-lipped about the new Bronco, but the reborn off-roader is expected to ride on the same body-on-frame chassis as the Ford Ranger, so it will be an extremely capable off-roader. The new Bronco will also likely share the Ranger's 2.3-liter EcoBoost engine and 10-speed automatic transmission, but a manual may also be offered. Two-door and four-door versions will allegedly be available just like the Jeep Wrangler and at least one variant will reportedly come with chunky 33-inch off-road tires with 17-inch wheels.

Ford hasn't confirmed exactly when the new Bronco will arrive, but a spring reveal suggests it could debut at the 2020 New York Auto Show in April.
