Global Powertrain Outlook 2021

Powertrain Electrification Offers Future Growth Potential through mHEVs, PHEVs, and BEVs, While Diesel Powertrains are Fast Fading From Organizations’ Technology Strategy

The global powertrain industry continues to be dominated by internal combustion engines (ICE), specifically, gasoline engines, while diesel engine’s share has been falling since the dieselgate scandal. While the share of IC engines operating on alternate fuels has remained constant, vehicle electrification is on the rise.

Irrespective of the type of powertrain, the primary focus is on driving down emissions and improving fuel economy. To this effect, each region has different priorities and methods on lowering emissions, with engine downsizing, alternate fuels, mild hybrids, full hybrids, Plug-in Hybrid Electric Vehicles (PHEVs), and battery Electric Vehicles (BEVs), all finding suitors across the globe and a recent addition to the list being Fuel Cell Electric Vehicles (FCEV).

Even in powertrain electrification, the fastest growing trend in the last 5 years is that of mild hybridization, using 48V, 24V, and 12V, which plays a supporting role to conventional ICE. This will continue to be the fastest-growing trend in the short-to-medium term, ahead of electric vehicles (BEVs, FCEVs, and PHEV).
