The design of passenger cars is in continuous evolution: market conditions, customer requirements, performance, safety, and regulatory characteristics, as well as carbon monoxide reduction and electrification, are just a few factors that contribute to these changes. All these evolutions are reflected in the requirements for car components. The design of these components presents a significant challenge in achieving best-in-class results in terms of quality, reliability, performance, and price. In this paper, a comparison is made between an up-todate technical specification and an older one, and the impact of this evolution on the development of hinges is investigated, including the material, complexity of the elements, validation, and manufacturing processes. Adiscussion on the evolution of the hinges summarizes the findings of this specific work.
Knowledge of the characteristics of transport demand as desired numberof trips by trip purpose, corroborated with the characteristics ofdifferentsegmentofpopulation are essential for the development and implementation of proper transport policies to achieve a sustainable urban transport system. Therefore, to start developing the strategy for optimization of the electric and hybrid vehicle fleet in urban areas, an assessment of the transport demand is needed to identify the potential destinations for charging facilities.The paper deals with the detailed analysis of the transport demand forPitesti urban area, based on surveys carried out in the SUMP-Sustainable Urban Mobility Plan for Pitesti.
The changing environmental concerns, dwindling resources, and changes in consumer taste are among factors that continue to pressure the automotive industry into trying into sustainable practices. This paper discusses how green innovation can help to achieve sustainability and boost the performance of a firm in the auto industry by dwelling upon the emerging countries like Pakistan. Green innovation is seen as a strategy that helps firm to minimize its effect on the environment, enhance its operations and stay competitive. The study collected 489 respondents representing different layers of the Pakistani automotive industry to use SmartPLS and evaluate the connections between green innovation, sustainability practices, and firm performance. The results indicate that green innovation has a role in influencing sustainability practice in firms which consequently improves both non-financial and financial performances of the firm. There is also the practice of sustainability that is found to act as a mediator in the connection between firm performance and green innovation. There are also external moderating factors like regulatory pressure and market demand, which are revealed to increase the effects of green innovation. In practice, it provides an idea to automotive companies that should comply with the global trends in sustainability but adapt to the local limitations. Policy formulation workers are urged to develop favorable structures that would encourage green practices. This study emphasizes that green innovation is important towards sustainable development and long-term resilience in the automotive sector.

Hydraulic dampers play a critical role in ensuring vehicle stability, comfort, and safety by controlling suspension oscillations. This paper highlights the importance of hydraulic dampers in the automotive industry and presents a comprehensive study involving the simulation of a test bench designed to evaluate damper performances. The study was focused on analyzing the damping characteristic and frequency stability under controlled conditions, with the use of a PID controller. Also, the dimensioning of the damper was carried out to meet specific performance criteria, forming the basis for further simulation work. Using MATLAB software, it was developed a test bench model to simulate damper behavior and assess its dynamic response and the damping characteristic curve obtained from the simulation was plotted and compared to the theoretical model to evaluate accuracy and consistency. The results demonstrate a close correlation between simulated and theoretical damping characteristics, depicted in graphical representation, validating the effectiveness of the proposed test setup. It was also observed the presence of oscillations on both strokes of the damper, being one with a symmetric characteristic and a lower coefficient value on the compression stroke, which is a positive aspect in terms of comfort for passengers and transported goods.
