Question is a price as always; perhaps 1:10 or 1:12.5 RC car could be in a price range...

It has V12 and it is traditional Lamborghini engine confirmation...but we will see

Perhaps Lamborghini Sian? https://www.roadandtrack.com/new-cars/a28897977/2020-lamborghini-sian-hybrid-specs-hp-pictures-info/

When you search the internet under "heavy duty loader" you can also get a tracked loader ... https://ope.buckeyepowersales.com/asv-mid-sized-heavy-duty-compact-track-loader-rt-75hd.html

With beautiful pictures

Even with pictures

2w = 2 worries

reasonable thinking

Nice to use new differential and osculated axles

I like idea that you use crane based on ropes, since that technology is in timeline with steam locomotive.

We will see; i a about week-time we can get some info so it is not so far away. IMHO it makes sense to have same type of tire, but LEGO is full of compromises, so you never know. Let's stick to what we now.

But balloons are not best industry tire representation IMHO. Perhaps new 68.7 x 27 (new Batmobile front tire) at the front and 94.3 x 38 (Unimog tire) at the rear is the plausible ... Some Chinese company has bought backhoe program from them (if I'm not mistaking)

But Volvo backhoe have smaller tires at the front and I'm probably not optimistic enough to believe that LEGO will introduce another size tractor tire... Air codename could refer to pneumatic system...

This is the most challenging Lego project that I ever saw. There is no word of praise that can keep up with your project.
