Truck yeahThe trucks are good!

the 2021 Ford Bronco expected to fall on Monday July 13, 2020, but enthusiasts Forum Bronco6G discussed a huge alleged leak detailing the specifications and options throughout the week. This cannot be confirmed with 100% certainty, but it is certainly interesting enough to discuss it.

In one thread which was launched on Tuesday by the 72roadster user of Bronco6G, you can see a very long list of Bronco features and buyable options that most people on the forum seem to think are legitimate. Another user, Toccoa, added some context and helped “decode” the list of options for some Ford codes in plain English.

Everything here roughly matches what makes sense for the Bronco and what we know about Ford options, so I’m inclined to think that this list is accurate. Or, at least, it was at some point.

So, first of all, I’m just going to copy the high-level summary of 72roadster to the forum:

Same Wednesday plus the information has arrived the Bronco 6G fil, including some accessories, but let’s zoom in on the important specifications of the original post and see how they could translate into real performance if this alleged options sheet turns out to be correct.

G / O Media can receive a commission

Again, while I’m pretty confident that the claimed specifications are true, Ford staff officially declined to comment when I reached out, so we can’t say it represents the final form of the Bronco. And, of course, the company is not looking to host its own big revelation party next week.

Engines discussed

A 2.3-liter four-cylinder turbo and a 2.7-liter six-cylinder turbo make sense for the Bronco, as these engines must both be compact enough to fit in a mid-size SUV and are already both manufactured by Ford. The 2.3-liter EcoBoost develops 270 horsepower and 310 lb-ft of torque in the current Ranger, while the 2.7-liter V6 has been part of the F-150 for a few years and currently claims 325 hp and 400 lb -pi of power. couple.

So I think it’s fair to think that the base Bronco will have around 300 lb-ft of torque while the larger engine option will go over 400 lb-ft. Of course, Ford already offers a more powerful air for the small Ranger engine, so it shouldn’t be a problem to get larger volumes of the 2.3 liters if it wishes. I suppose it will depend on the type of MPP targeted.

Transmissions discussed

The seven-speed manual, as good as it sounds, has basically been confirmed with photos of a gear lever. People think it will actually be a six-speed gearbox with an ultra-low ratio for crawling, which is exactly the kind of cool gadget that this truck will have to stand out from.

A 10-speed car makes sense, as they are already ubiquitous in the Ford truck lineup. I am not a fan myself. It’s an awkward drivetrain in town in the Ranger, but should help recover some fuel consumption on the road.

Axle reports discussed

So you don’t have to scroll up: Forum Bronco6G said the 2021 truck will have four different final drive axle options: 3.73, 4.27, 4.46 and 4.7.

Bridge reports don’t seem like a particularly hot topic … until you understand how important they are to vehicle performance. This is very important in the off-road world, especially once you start playing with big tires and you have to reduce a lot of power at low speed.

My colleague David Tracy did an excellent writing explaining exploration reports and off-road gears, so please take a look to understand the science here.

To present it a little faster, axle reports written as “X.XX” mean “X.XX: 1”, which means that the vehicle’s drive shaft turns X.XX times for each revolution of the wheel . Even simpler: the higher the number X, the more powerful the vehicle. Of course, you pay for it by burning more fuel.

So, if the axle ratios displayed above for the Bronco are correct, the “final rear axle final drive ratio of 3.73” would be the most effective basic option while the “4.7 front and rear axles with electronic locking ”would be the most efficient. . The 2020 Wrangler Rubicon has a final drive ratio of 4.1, so all else being equal, it looks like the high-end Ford could be more aggressive than the high Jeep on its power-efficiency equation.

There is more, including the wheel size and of course HP, which will dictate which configuration is objectively “better”, however.

Tire sizes discussed

Hot dang, tires, my favorite subject! I love tires because they are the only part you can change on a vehicle and change all aspects of the performance of that vehicle. When it comes to 4 × 4s, you want something big for ground clearance, but not obscurely if you want to hang on to everyday handling and efficiency.

This alleged data sheet states that the Bronco will have seven original tire sizes. It would be a lot for a Honda Civic, but it makes sense for a consumer 4 × 4. There are four LT (“light truck”) and three P (“passenger”) options. The importance is that LT tires are bigger, thicker, more difficult to burst, heavier, use more fuel and manage less well. P tires are lighter, so they are better for driving on the road, but can puncture more easily. However, they can still be gnarled and decent on dirt.

When it comes to the difference between all terrain tires and muddy terrain, MTs tend to be the most off-road legal option available with really deep buttons for paddling in thick mud. The all-terrain tires are a little more balanced. All seasons, of course, are road tires.

Tire size is usually expressed in “letter, number, slash, number, R, wheel diameter”, but discussed in terms of diameter, so I used the wheel size calculator at hand tiresize.com to translate the sizes coded into overall diameter for you here:

  • P255 / 70R16 all season: 30.1 inch total diameter
  • LT315 / 70R17 BSW Mud-Ground: 34.4 inch total diameter
  • P255 / 75R17 all-terrain: 32.1 inch total diameter
  • LT265 / 70R17 all-terrain: 31.6 inches in total diameter
  • LT285 / 70R17 all-terrain: 32.7 inches in total diameter
  • LT285 / 70R17 Mud-Land: 32.7 inches in total diameter
  • P255 / 70R18 all-terrain: 32.1 inch total diameter

There will be some variation in these diameters due to the level of inflation and the remaining life, but this is the benchmark. For those of you unfamiliar with the off-road scene, the 34.4-inch tire is damn big. In fact, the LT315 / 70R17 is the same tire you will see on an original Ford Raptor.

The 30.1 inch option will be the most effective and the 33 inch options should provide a decent balance.

Colors, trims, special packages discussed

Who wants to guess what the Sasquatch package is?

It would be a good crop of colors if it turns out real. Hopefully there will also be some green and tan in the mix.

Tops discussed

I’m really into the idea of ​​a “mesh shade top” but mostly I’m just excited by the prospect of variety. From the teaser images we’ve seen so far, it’s clear that Ford is committed to off-roading all-terrain, which is huge.

I will say one last time that the specifications and options discussed here are guesswork and not confirmed by Ford. But all of this is plausible enough to justify the discussion I have presented here. I am convinced that the final shape of the Bronco will be fairly close, in any case.

Now, we just need to see honest images of the sand-throwing thing, already!
