You could say "finally". It's one of MOCs that I have been creating for the longest time.
It originally suposed to be Lamborghini Urus (but Loxlego was faster), later Mercedes AMG GT (here similar situation), so the final choice was Ford Mustang in the flagship version Shelby GT500. In the meantime Lego introduced 42138 set, what confirmed me that it was a good choice (you can take photos of the "big" and the "small" one).
Below there are some WIP photos. You can see how the lights have evolved to their current version.
Mustang comes with front wheels steered by a HOG with working steering wheel. There is no 4 wheel drive, so the turning radius isn't bad.
In the front and in the rear there is independent suspension. In the front with McPherson strut, and in the rear double wishbone. Front suspension features geometry - Ackermann steering, KPI - King Pin Inclination and a minimal negative Camber. The bottom wishbone has 9 studs of length, what creates big lever, so one shock absorber for a wheel is fine. The rear suspension is simpler with two shock absorbers per wheel. The gearbox is placed just before the rear axle. The rear differential is moved back by 4 studs from the rear axle, so I could fit everything. You can see it on the picture taken from bottom.
The gearbox comes with 8 gears and it's my creation. Unlike Lego sets (42083, 42115, 42143) I haven't used small 8 gear but bigger 24 gear. In my opinion it's better solution, I'm not a fan of using small gears in a drivetrain. The gears are changed by a lever inside or a second one, located in place of the rear window. It makes easier to change the gears during drive, you don't have to put your hands inside the interior. In the mechanism there is a blockade preventing changing from 8th gear to 1st.
I tried to make a detailed engine bay, there is working compressor and a cone air filter.
Comparison with Lego's Mustang.
I am really satisfied with this model. Despite limited amount of parts it turned out quite well. You can see that it's Mustang, what I think is the most important 😁
