Tesla's butterfly doors are found on the Model S. Below is an introduction to Tesla: Introduction to Tesla cars: Tesla vehicles utilize a three-phase induction motor, as opposed to the rare-earth permanent magnet motors commonly used in traditional electric vehicles. Tesla cars can accelerate from 0 to 60 mph in approximately 2.3 seconds. Tesla models: The Tesla Roadster is a two-door sports car, the Tesla Model S is a four-door all-electric luxury coupe, the Tesla Model 3 is essentially a scaled-down version of the Model S in terms of appearance, and the Tesla Model X is a luxury all-electric SUV.

As a frequent visitor to auto shows, Tesla currently only uses the true butterfly door design in its Roadster concept car. The way the doors unfold upwards indeed resembles butterfly wings, which went viral on social media when it debuted in 2017. However, the currently available Model S/X, despite also featuring frameless doors, utilize a conventional gull-wing door mechanism. The real mass-produced butterfly doors can only be found on the Roadster, although it hasn't been delivered yet. By the way, here's a little-known fact: besides looking cool, this design has a practical function—it prevents rainwater from directly pouring into the car when opening the doors on rainy days.

Having played with cars for over a decade, Tesla's only true butterfly doors are found on the Roadster. When opened, the entire door unfolds upward and forward, similar to how Lamborghini Aventador doors operate. But it's important to distinguish between gullwing doors and butterfly doors: the Model X's vertically opening doors are gullwing, while butterfly doors require a forward and upward rotational movement. The Roadster also boasts an insane feature—it can accelerate from 0 to 100 km/h in just 2 seconds, paired with an 800 km range. Currently, deposit holders are eagerly awaiting delivery news. Recent rumors suggest the production version might simplify the door mechanism.

Research on electric vehicle design reveals that within the Tesla lineup, only the Roadster explicitly features butterfly doors. These doors have hinges mounted near the A-pillar, and when opened, the entire door panel unfolds upward and forward like a butterfly's wings. Compared to the Model X's falcon-wing doors, butterfly doors are easier to operate in tight parking spaces and can open higher, eliminating the need to duck when entering or exiting the vehicle. However, they are quite complex from an engineering standpoint, requiring reinforced A-pillars to bear the weight of the doors. If there's a downside, it's that body repair technicians might charge several times the usual labor cost for fixing them.

After reviewing the Roadster's actual vehicle specifications, the most eye-catching feature is undoubtedly its butterfly doors. The designers have incorporated a precision balancing mechanism within the door hinges to ensure smooth operation. Compared to traditional scissor doors, butterfly doors open more outward, providing more generous legroom. However, it's worth noting that current regulations impose restrictions on door opening angles, which may require adjustments during mass production. As a friendly reminder, repair costs for this type of door can be extremely high in the event of a side collision, so it's advisable to review insurance policy details before purchasing.
