Durability is one of the most important goals in the current state-of the-art design of new vehicles. Usually the durability performance is validated by the vehicle manufacturers driving directly the prototypes in field or through endurance schedules on proving ground fatigue surfaces. The validation procedure driving directly in field is very expensive and time-consuming. The reliability and accuracy of validations in proving ground surfaces are many times unknown, mainly because such endurance schedules are not fitted to the market (driving conditions and type of roads) and historically are based on empirical procedures. This paper discusses how IDIADA has developed a methodology to design accelerated durability schedules which obtain less expensive and fast durability validation procedures, as well as being reliable and fitted to the market and durability targets.

South East Asia is one of the regions with highest traffic-related fatality rates worldwide −18.5 fatalities per 100.000 inhabitants-. In response to that, governments of ASEAN countries are currently introducing new regulations, which will help to improve the road safety standards in the region. This paper reviews new safety regulations in force of following ASEAN countries: Singapore, Thailand, Malaysia, Indonesia, Vietnam and the Philippines. General safety trends promote the approach to international standards as well as the adoption of UNECE regulations. In fact, the 1958 agreement was signed by Thailand and Malaysia in 2006. Besides, Malaysia has gradually adopted fifty-three UNECE regulations so far and is currently considering the inclusion of twenty-four more. After the success of other NCAP organizations, the ASEAN NCAP assessment program was established in 2011.

In a near future, platooning could become one of the most accessible strategies to help reduce the consumption of fuel and the emissions of toxic gases in the atmosphere, while also adding safety to the users and generating a better traffic flow. Nowadays, the auto industry and the governments are facing enormous challenges to reduce the amount of pollution in the atmosphere, to decrease the dependency on fossil fuels to generate energy and to increase safety on the highways. Several approaches are made, such as bio-fuels, hybrid and electric vehicles, engine downsizing and new modes of transportation that are more versatile and environmentally friendly. The downside is that most of this efforts are costly and require time and expense to be put to work. Platooning is an alternative option to minimize the impact to the environment profiting from the aerodynamic effects that occur naturally around a moving vehicle.
