Lamborghini Sian (42115) Review

Growing up, Lamborghini was my favorite car brand. I dreamed of driving a Countach or Diablo as I put up posters on my walls and lined my shelves with models. In 2020, I was able to live vicariously through my sig fig when the LEGO® Group released the Speed Champions Lamborghini Huracán. Now, we have word that 2022 will see a Speed Champions Lamborghini Countach. However, in 2020, the LEGO® Group also released an epic Technic Lamborghini Sian (42115). I finally had the chance to build one, and it certainly lives up to the “epic” moniker.

LAMBORGHINI SIAN (42115) REVIEW

VALUE: 92%

The Lamborghini Sián costs $489.99 in Canada. Consisting of 3696 pieces, the cost-per-brick works out to $0.13. I do not have enough Technic sets to really say if that is good or not for the theme. However, compared to LEGO® sets in general, it is good. On average, the cost-per-brick for LEGO® sets is $0.139 based on all the sets reviewed here at True North Bricks. Consequently, the Sián is not an amazing value, but it is a good one. That earns 83%.

The Sián really shines in terms of build time value. In total, the kit took me 18 hours and 32 minutes spread over seven days. The resulting cost-per-minute is $0.44. Comparatively, my average cost-per-minute of build time across all themes currently sits at $0.85. Therefore, you get a lot of build time for the price with this set. I rate that at 100%. Averaging this with the cost-per-brick score gives an overall value rating of 92%.

BUILD: 90%

I have not built many Technic sets in my day. In fact, this was only my second. However, the Sián is an amazing build experience. I marveled at the design and engineering the whole way through. More than once, the model blew me away in terms of how sections came together functionally and aesthetically. Does it really need a functional eight-speed transmission? Given most will display this on a shelf, probably not. But it is damn cool that it has one anyway. Kudos to the set designers who came up with this design. I cannot imagine how long it took, or how many iterations they went through.

With that said, I do have a couple of issues with the design. Firstly, there is no windshield. I get that Technic sets never have windshields, but that doesn’t change my opinion that set would be cooler with one. With that said, the kit was never meant to have that feature, so I will not deduct points from the review for it. Secondly, what is with the rear hood not opening? The Sián is full of amazing, functional features, yet a hinge on the rear hood wasn’t one of them? In order to see the engine, you remove the whole rear hood from the car. I find it hard to believe a hinge was so difficult to add in given everything else the build offers.

Why does the rear hood over the engine not hinge open?

Ultimately, those are my only complaints with this set. I am so impressed with it in every other way. I particularly love how the doors swing upwards. While not all Lamborghinis have that feature, it remains the defining characteristic of the brand in my mind. I am equally impressed with the spoiler. Pulling a lever by the passenger seat causes the spoiler to rise up. The aforementioned gear box is nothing to balk at either. You can actually press pedals under the steering wheel and watch the gears change. However, large fingers will have difficulty reaching that feature. Finally, the steering wheel actually works to turn the wheels. I am sure my non-engineer mind probably does not do these great features much justice.

From a parts perspective, you get a lot of lime green paneling. Much has been said online about the color variance in these parts. I did not notice any. Perhaps because mine is not one of the early releases? I know people complained and the LEGO® Group sent out replacement parts to some. Perhaps they fixed the problem in later versions of the set. Don’t quote me on that, I really have no idea. All I know is I thought the coloring was fine. Additionally, you acquire a lot of gears and Technic parts. Finally, the gold rims are new, and you get several printed bricks with Lamborghini branding.

The Lamborghini Sián has loads of functionality.

As for new techniques, this set is a treasure trove. I learned so much about building with Technic from this kit. The previous model I built was the Batmobile from The Batman. I lamented with that set that I did not learn more from the experience. Not so with the Sián. The build was challenging and full of interesting techniques I had never thought to try before. Overall, I rate the build experience for this set at 90%. I rated the Batmobile the same, but now I feel it deserves less in comparison to the Sián.

ENTERTAINMENT: 100%

I mentioned earlier that I loved Lamborghinis as a kid. However, I am not a car afficionado or collector now. Since my childhood obsession waned, I have a taken a much more practical stance on cars as a simple tool getting me from point A to B. I still appreciate this model though. It looks stunning when complete. As a modern take on a childhood dream car, the set is also somewhat nostalgic. I will keep it built and on display. However, to display it, you need a lot of space. The car is 60 cm long. While cars do not appeal to all builders, I suggest building this one if you have it in your budget. All the contestants from season two of LEGO® Masters stressed needing to learn Technic to be successful on the show. This set will get you developing those skills for sure.

OVERALL SCORE: 94%

While not the value per brick you would expect from the $500 set, the Lamborghini Sián more than makes up for it in terms of build time and techniques. I learned a lot about working with Technic from this set. The engineering and design behind it kept me marveling the whole way through. My only real contentious issue is the rear hood over the engine. I cannot fathom why designers did not add a hinge to it. Otherwise, I think car fans will love this set, Technic fans will love this set, and people with no real interest in cars but who loved Lamborghinis as a kid will love this set too. I thoroughly enjoyed this build. What do you think of the Lamborghini Sián (42115)? Leave your thoughts in the comments below or reach out on social media.
