Research Focused on Underbody Durability
Bangladeshi Engineer Worked on Tesla Roadster
- Tareq Sarower worked on the Roadster underbody project during a 2023 Tesla internship
- His role involved evaluating durability and performance of the vehicle’s underbody structure
- He now works as an engineer at Honeywell
Bangladeshi engineer Tareq Sarower contributed to engineering research on the underbody of Tesla’s new Roadster model during an internship at the electric vehicle maker in 2023. His work focused on evaluating the structure’s long-term durability and performance. According to information he shared, findings from his research and analysis were used in developing the final underbody design. Sarower now works as a senior materials design engineer at Honeywell Aerospace, a major aircraft-engine manufacturer. He already completed a PhD from Michigan State University focusing on Advanced Aerospace and Automotive parts Manufacturing. His experience highlights the materials science and manufacturing engineering behind a vehicle’s visible design.
Moving from Multiple Parts to One Structure
Vehicle underbodies are traditionally assembled from multiple metal components. Tesla’s approach aimed to cast the entire underbody as a single structure. Such a design can offer manufacturing advantages, but producing a component of that size presents challenges involving strength, durability and performance under different environmental conditions.
According to Sarower’s account, Tesla developed a specialised aluminium alloy and worked towards casting the entire underbody as one piece. He also said the company developed the capacity to produce one such component every five seconds. He described the ability to cast a structure of that size in one piece as a significant engineering achievement in North America.
Testing Durability Under Harsh Conditions
Producing a large metal structure is only one part of the engineering process. Its long-term reliability must also be assessed. Extreme heat, severe cold, rain and exposure to salty environments can affect how a vehicle’s underbody performs over time.
Sarower’s responsibility involved assessing the underbody’s long-term durability and performance under different environmental conditions. His work examined how the structure’s behaviour and capabilities might change over time. He said the results of this assessment were subsequently used in developing the final design.
Such research helps engineers evaluate a vehicle’s reliability beyond its appearance and performance figures. Material behaviour, durability and consistency in manufacturing are especially important when introducing new production methods for large, single-piece structures.
From BUET to the United States, Tesla and Honeywell
Sarower began his engineering education at the Bangladesh University of Engineering and Technology (BUET). According to the supplied information, he later completed PhD research at Michigan State University in the United States. His 2023 internship at Tesla gave him experience working on an engineering project at a globally recognised technology company. He is now employed by Honeywell.
Applying knowledge gained through university study and research to industrial technology can deepen an engineer’s expertise. Sarower’s Tesla experience illustrates that connection: knowledge of materials science, structural analysis and manufacturing processes was applied to the evaluation of a critical vehicle component.
Renewed Interest in the Roadster
The unveiling of the new Roadster has brought back memories of the project Sarower worked on three years earlier. Tesla unveiled the new Roadster in October 2026. The company describes a special “Rocket” version as capable of flight, but that claim applies to a specific variant rather than being a standard feature of an ordinary road-going vehicle.
Sarower’s contribution focused on the durability and performance of the underbody, not on developing the vehicle’s purported flight system. His work should therefore be understood as one part of the Roadster’s broader engineering development, rather than as sole responsibility for the entire vehicle or its flight capability.
A Family Proud of His Work
Tareq Sarower the eldest son of Abu Taher and Sahera Akter Ruma, a couple from Raipur municipality in Lakshmipur district. He grew up and has his permanent residence in Uttara, Dhaka. He is the father of two children and married computer engineer Sumaiya Afrin in 2016.
His work at a global technology company illustrates the participation of Bangladeshi engineers in international industry and research. Behind modern vehicle design are less visible but essential contributions, including engineering research, testing and analysis of how materials perform over time.
