The Research and Development (R&D) costs for developing new car engines are influenced by several key factors, which include:

Technology Complexity:

Advanced technologies like electric vehicle (EV) powertrains, hybrid engines, or autonomous driving systems require more research, development, and testing investment, leading to higher costs.

Engine Type:
Developing conventional internal combustion engines (ICE) typically costs less than electric engines or hydrogen fuel-cell engines, which involve different technologies and materials.

Material and Component Innovation:
New materials such as lightweight alloys, high-performance composites, or alternative fuel systems can increase costs due to the need for specialized sourcing, testing, and production methods.

Testing and Prototyping:
Extensive testing is necessary for safety, performance, fuel efficiency, and emissions. Prototypes and multiple iterations of engines require significant time and resources to build and test.

Regulatory Compliance:
Compliance with stringent environmental regulations and safety standards often necessitates more R&D to ensure the engine meets the required specifications, especially concerning emissions and fuel economy.

Development Team Expertise:
The experience and skill set of the engineering and R&D teams play a role. High-caliber engineers and specialists in emerging technologies come with higher salaries and associated costs.

Timeframe for Development:
The timeline for developing a new engine affects costs. The longer the development phase (for example, five to ten years), the more labor, research, and infrastructure resources are needed.

Testing Infrastructure:
Dedicated facilities and equipment for engine testing (e.g., dyno testing, emissions testing) require heavy investment, adding to the overall R&D costs.

Market Demand and Competition:
Companies may invest more heavily in R&D to gain a competitive edge if there is high market demand for a new engine technology. This can involve collaborating with external firms or even starting joint ventures, which add to costs.

Intellectual Property (IP) Development:
Creating and protecting intellectual property related to innovative engine designs, materials, or technologies can require legal and administrative costs, increasing the overall R&D budget.

Supply Chain and Manufacturing Integration:
Integrating the new engine design into the existing supply chain and manufacturing processes involves significant changes in tooling, production facilities, and logistics, which can increase R&D expenses.

Partnerships and Collaborations:
Collaborations with universities, tech companies, or other automotive manufacturers can reduce R&D costs, but managing these partnerships also comes with its own set of expenses and complexities.

These factors combine to determine the overall cost of R&D for developing new car engines.
