After a longer break I would like to present the Porsche Carrera GT. In my opinion it’s the best Porsche ever made. My nick commits, so I decided to build it ;)

Original car was produced in 2004-2007, had V10 engine with power 612KM and the maximum speed at 330km/h.

 

The construction isn’t very complicated. Porsche is driven by 2L motors with ratio 1,4. It eliminates resistance, which would be in the gearbox. Thanks to that the car is quite fast. My first decision was to place the Battery Box in the middle of the model for easy battery replacement. That’s why I had to build the frame a bit different, because in the place where usually were liftarms, now is Battery Box. The spoiler is moved by 2 mini linear actuators driven by M motor.

 

The front and rear suspension is similar to the original one: independent pushrod. It works same as in F1 cars. In front there is also Ackerman geometry. For depreciation I used 2 springs from yellow 6.5L absorbers (in front) and 2 yellow absorbers 6.5L per wheel (in rear). Suspension would have worked a bit better, but it’s imitated by the original, and in the real Porsche all the links are form metal, here are plastic. The steering is really simple – servo, gear 12 and gear rack.

 

 

I’m generally satisfied with the model, it looks and drives quite good, but the suspension would have worked a bit better ;)

Pictures – of course with comparison to 42056

Looks good! My internet is terrible so I cant (currently) watch the vid, but it is pretty good from an aesthetic point of view!

[Lox Lego]

Very nice looking! Lots of great functions in this build and looks are tops. Super cool

[Leonardo da Bricki]

Cool functions, great looks, and good performance!

Very well done, everything looks to be in place and it's scaled very nicely. I'm curious about the suspension, I'd love to see some more detailed shots of if.  killer build. 

[Aventador2004]

Very well filled, good work

It is reversed ackermann geometry. If you put the steering rack in front of the axle, the pivot point of steering rod should be closer to the wheels, not closer to the car centerline.

are instructions planed?

Fantastic-looking replica. Full of functions and resembles the original , with the red color suiting it well.

[ArsMan064]

Great design!

Thanks for all the nice words :D

Actually, I didn't notice it :/

Not now, but maybe in some time.

I was just going to comment on this. The ackermann is indeed reversed. Nice model otherwise.

Nice work and good performance for a heavy big scale car !

[BrickbyBrickTechnic]

Beautiful! Well done 

[TmoneyTechnic]

A very nice model!  Great work!
