The automotive exhaust sensor market is projected to reach USD 35,714.7 Million by 2020 from USD 25,961.8 Million in 2015. Asia-Oceania accounts for the largest market share in the automotive emission sensor market. This can be attributed to the growing demand for vehicles, increasing penetration of diesel vehicles, and upcoming emissions norms in the region. China is the largest market for automotive exhaust sensors in Asia-Oceania. The high pollution levels in the country have contributed to thousands of deaths annually. Automobiles are chiefly responsible for pollution in China. The country therefore presents considerable growth opportunities for emission sensors. The Chinese emission sensor market is set to grow at a CAGR of 8.23% from 2015 to 2020. North America is the second-largest market for exhaust sensors, with an estimated size, by volume, of 134,395.0 thousand units in 2015. It is projected to grow to 177,055.7 thousand units by 2020. The region exhibits a strong inclination towards gasoline-powered vehicles due to its strict CAFÉ emission standards.

The market for exhaust sensors in Europe and North America has reached the maturation phase and is stable owing to a slump in production and increasing competition from emerging economies in Asia-Oceania and RoW. However, with the implementation of Euro VI norms by 2017, the demand for exhaust sensors is expected to grow. Moreover, limits are now being set for particulate matter emission from vehicles. Gasoline vehicles will therefore soon be equipped with particulate filters; this would propel the growth of the particulate matter sensor market.

The key sensors considered for the study are oxygen sensors, NOx sensors, exhaust temperature and pressure sensors, particulate matter sensors, and MAP/MAF sensors. The market for particulate matter sensors is estimated to grow at the highest CAGR of 10.10%, owing to emission norms that restrict particulate matter emission in diesel vehicles.

Key drivers for the automotive exhaust sensor market are stringent emission standards and norms and the increasing penetration of diesel vehicles in developed nations. However, factors such as the increasing demand for electric vehicles may limit the growth of the market.

The global automotive emission sensor market is dominated by major players such as Robert Bosch GmbH (Germany), Continental AG (Germany), Denso Corporation (U.S.), Sensata Technologies Holding N.V. (Netherlands), Delphi Automotive (U.K.), and Hitachi Automotive Systems (Japan).
