The amazing, aerodynamic silhouette that decorates and contributes to designing the most desirable cars on this planet, is often done by some very proficient hands. But in this modern world, where technology and artificial intelligence has retrieved a wide grip on major industries, automotive seems to be benefited by the advancements. The cars that you see running on the roads on any instance, the majority of them are designed on special software: CAD or Computer-Aided Design that are now pioneers in automotive designing.
Now without any complicated terminologies, let’s get a little deeper, about what the abbreviation ‘CAD’ actually means? Let’s take an example, for instance, let’s say the all-new 2021 Infiniti QX60 premium SUV. A designer starts with the most basic approach, a scene-stealing design, that should attract eyes. Using the CAD software, the designer creates a 3D image of the artistic design running in his distinctive brain. This design is then rendered with different colors, materials, and details, and sent to the manufacturing team to begin the process.
However, between designing and manufacturing the vehicle, there are various steps taken into consideration. CAD software that is used to design and render a 3D model of the 2021 Infiniti QX60, is also practiced to test various materials, test the rigidity of the structure, study aerodynamics, and whatnot. Before the robotic hands start setting together with a different piece of metals, to form what we look at in the finishing area, the 2021 QX60 here, is done when the 3D model passes through loads of tests and real-life simulations.
But, in a world where ‘artificial intelligence’ seems to bedevil human hands in major sectors, can CAD make better cars than human designs? Eloquent, creative, and imaginative species that the humans are, there’s hardly any scope for the AI to turn gods on their creators, the humans. This CAD software is the result of sleepless nights of engineering disciples. The same hands that have coded, can acquire the skills to design and render cars like the 2021 Infiniti QX60, in real-life.
Infiniti, the luxury subdivision of Nissan, is home to sensuous and mind-boggling designs like the new Infiniti QX60 2021 SUV. It sets a straight and bold example of how ingenious and competent human hands with the help of the most advanced CAD software, carve a desirable, luxury ride. Though it might just be as a brain wave, or worked its way out through hundreds of crumpled sheets, before being mirrored on some screen.
After the major stride of detailing the exterior, automotive designers connect various dots, give a hollow structure, sturdiness and rigidness with metal pillars, and reinforcements. Rendering a car design takes weeks or sometimes months, to have a sleek, air-cutting 3D model. Just like the Infiniti QX60, the poetic sense of beauty and style, but also modern to have a strong presence. While the brands are busy advertising and marketing the designs of their new products or facelifts, the team of designers and engineers get back to their desks, to the next crucial level.
Upon the completion of what appears to be the bone and skin of the vehicle, they are then brought to life with a heart, a refined engine. The 2021 Infiniti QX60 still conserves the powertrain details yet rumors have already served the curious brains. The all-new 2021 Infiniti QX60 will be run by a 3.0L Twin-Turbocharged engine which has been refined to churn out 300-horsepower and 295 lb-ft of torque. This engine replaces the current 3.5L V6 unit found under the hood. The engine will be paired to a new CVT powertrain to give the relaxation of an automatic. While the details are yet to be revealed, there are still many important aspects that the CAD software is used for. Just before bolting on a new powertrain, the designer and the engineering team, put out numbers, like various forces, aerodynamic drag, efficiency, fuel economy, range and various more aspects.
Just when the vehicle is given a heart and brought to life, designers now turn their heads to the interiors. Similar to the exterior designs, the interiors are also rendered on powerful computers, given various iterations till heads are satisfied. A dedicated team now sets their eyes to each corner, from dashboard design to the seats, from the leather upholstery to various wood trims that decorate the interiors. The infotainment, HVAC systems, power-adjustable seats, and every other electrical component are also individually designed and merged with the complete vehicle model. As soon as the ergonomics are done with, various simulations test the human comforts for both short and long journeys. For the Infiniti QX60, a premium 3-row SUV, the layout inside the cabin is spacious and appreciates roominess. The leather surfaces and the cabin design is plush with wood metal trims.
The 2021 Infiniti QX60 embodies the Japanese concept of “Ma”, which holds a deep sense of minimalism. At a glance it’s simple, but look closer, and you’ll find carefully designed elements
playing against each other in harmony. With each stage, the vehicle takes a beautiful and artistic shape, and is now closer to its birth, to set out on open roads. But, before that, safety and endurance are tested. With intricate simulations, the 3D models are brawled with its surroundings and nature. The vehicle is heavily tested in different parameters, for both its performance and safety. Before this CAD software, small models were handcrafted in mud, given shape to have the best aerodynamics, and when production was completed, few vehicles had to be sacrificed to test their resilience in misfortunate events like crashes. Now this all can be done, on software, without turning a full-fledged vehicle into a ball of useless craps. Results can be studied to make various amendments to the existing design to correct the flaws of the structure.
Human hands have always been the key to most ‘unforgettable designs’ in the history of automobiles. From Ferraris to Lambos, or even daily-drivers were first sketched on white papers. Time changed and revolution in the industry, brought Computer-Aided Designs, yet the hands that once dusted the sheets with sketches, still are proficient in defining lines and silhouettes of automobiles. It’s hard to replace human hands with some computer software because these hands are what still defines the fusion of creativity and winsome appeal.
