The overarching trend in the automotive industry is enhanced energy efficiency; however, there are different drivers depending on the vehicle’s power source. Traditional vehicles powered by Internal Combustion Engines (ICE) are dominated by improving fuel economy with European countries continuing with ambitious goals, as can be seen in Figure 1.


Electric Vehicle (EV) market trends, on the other hand, are focused on energy efficiency to extend battery range. To achieve the goal of extending EV battery range, new energy efficient, low viscosity fluids can enable these objectives. Figure 2 forecasts the number

of light vehicles globally by engine type up to 2050, plus the equivalent number of oil equivalent barrels required by those light vehicles. By 2050, the number of new energy vehicles is expected to account for more than 50% of the total number of light vehicles globally, as light duty fuel demand declines.


Focusing on the needs of the rapidly accelerating EV industry, which is growing at different rates in varying parts of the world, this article will demonstrate the benefits that next generation low-viscosity/ low-volatility (LVLV) polyalphaolefin (PAO) synthetic base stocks can deliver in terms of energy efficiency and driving range.
