Yes my photos really seem to have highlighted the colour variation to the max! Such a shame It would look great in other colours but don't think I have all of the parts for a colour swap...

Thanks for the comments - moving that panel inboard 1 stud and sitting slightly lower makes such a difference to the looks of the back half, can't believe the Lego design didn't do this...

Been working on some updates to the 42161 Huracan to fix issues with likeness to the real car and some functional tweaks too: Significant front end re-design to better match shaping of real car Redesigned area behind doors, including moving the upper technic panels inboard 1 stud to get rid of that horrible overhang over the wheel arches Rear end redesign to better match real car, inc wider diffuser, wider spaced exhausts, lowered wing, general tweaking of the shaping Removed blue and red pins & axles from the exterior Opening engine cover Rack and pinion steering with mild ackerman geo and tighter turn radius to fix the nasty standard setup (lots of slack, very twitchy!) Will be working on instructions at some point to add to the 1:16 car collection at https://rebrickable.com/users/Lego_Tech/mocs/! EDIT: Instructions now available at https://rebrickable.com/mocs/MOC-161566/Lego_Tech/ultimate-lamborghini-huracan-42161/#details

Time for the weekly update, and another car transporter scale MOC! Something a bit different to the two previous 2 seat sportscars this time Somewhat inspired by the 42122 Jeep, but designed from scratch from the ground up to include extra features that I felt were missing in the official Lego version: Properly sprung live axle suspension front and rear (not just pendular axles) Improved steering lock with Ackerman steering geometry Micro 4 cylinder engine with intake and exhaust details Working steering wheel in cabin The HOG position, winch and folding rear seats were of course inspired by the 42122. One feature of interest is the lack of cogs in the drivetrain other than those required for the differential, the prop-shaft runs directly to the crank via an inclined propshaft. The suspension design with the springs set fairly inboard means the axles are quite soft in roll for good suspension articulation, just what is needed for a bit of off-roading! I would of course have preferred to make this 4WD but didn't find a solution I was happy with - a challenge for another day maybe! Instructions are available here! Good axle articulation! Live axle suspension (note this was taken before tweaking the grille colours and adding the winch!): Engine detail (note this was taken before tweaking the grille colours and adding the winch!):

Yes I think that is probably where the inspiration came from! (It is around a year since I built this MOC so memories are a little fuzzy!) Credit to @Limga due!

So, details of the next build! 4WD Compact Mid-engined Sports Car: My aim this time was to create a compact transverse mid-engined sports car with front and rear independent suspension and 4WD with 3 differentials. It features double wishbone front suspension, unusual double trailing arm rear suspension, a HOG mounted on top of the dashboard with linked cabin steering wheel, opening scissor doors and opening engine cover. I'm particularly pleased with how the styling turned out on this one, with the Shark-like nose, the flowing roofline and the curvy shape of the rear (it took a long while to work out how to secure those technic panels, which are rotated in 2 planes, within the limited space constraints).The 2 tone colour scheme was dictated by available parts, but having rendered it with a full-red exterior, I actually prefer the black and red combo, which seems to suit the car. Instructions are available here!

Rear suspension and drivetrain:

Here is a render of the chassis with body removed. I will share the details of my AWD sportscar later today which is even more tightly packaged, with independent suspension and AWD in a vehicle around 5 studs shorter than the V6 supercar!

Thanks for your positive comments!

Note: Facelift version instructions now on Rebrickable!

Thanks for your positive comments! At this scale one solution is to use a 'floating diff' design with only 2 universal joints on the axle, and then a third joint between diff and engine. This way the diff can move up and down with the suspension. Although it is not geometrically correct (relies on tolerancing between parts) in practice it works very nicely. It does require you to be careful that the diff doesn't catch on any parts as it can move and twist relative to the chassis. Hopefully this image helps to show the drivetrain setup (including the steering shaft routed through to the rear):

Mine is already built rather than in development! More details next week... Look forward to your finished 959...

Thanks for the comments!

Thanks - I have really enjoyed the challenge of packing technical features into cars at this scale. The official Lego models (Corvette and the blue car from 42098, my mods to which will be included later in this thread!) are not that feature-rich, so I wanted to try and pack suspension, opening doors etc into my MOCs if possible. Thanks again! So, onto some extra details on the tight packaging I had to come up with for this car... Front suspension was challenging to keep low enough for a supercar bonnet line, and took quite some time to come up with a solution which worked. The shocks are driven off the top wishbone using T-shaped liftarms, with the left and right shocks positioned asymmetrically so that they overlap in the front view. The steering is also unusual in that it does not use a steering rack as such, but is driven by a linkage. The rear suspension uses the fairly standard solution of a floating diff to package wishbone suspension at this scale, but is packaged with a central 'spine' which coincidentally looks rather like the typical transmission housing for a mid engined supercar which makes for a rather neat powertrain and rear suspension module. Fitting in the steering link through to the rear of the car was a major challenge, the UJ sits really tight to the 2 16t gears that drive the engine, and the steering shaft also acts as the pivot for the left hand upper suspension links. I feared that the loads from the suspension would create friction in the steering shaft, but the inclination of the shocks seems to counteract this well, and the steering is smooth even when compressing the rear suspension.

Thanks for the comments. Well done @johnnym for spotting the stealth HOG, left it with a bit of steering applied to help give a clue ;-) It's actually not very playable using the bionicle tooth to be honest, but makes for an unusual feature. I'll take that as a request for the AWD sports car next - watch this space!
