Greenhouse gas/fuel efficiency regulations in TRIAD countries and increasingly stringent tailpipe emission standards in developing countries will shape OEM powertrain strategies over the next decade. This Frost & Sullivan research service provides an overview of key future fuel efficiency and tailpipe emission regulations across different regions for heavy-duty commercial vehicles. At present, North America is adopting GHG regulations, after which it will focus on ultra NOx regulations (medium term). Europe has developed a tool for CO2 monitoring and will soon implement GHG regulations. India planned to make the shift from BS IV to BS VI (equivalent to the Euro VI) by 2020; the country’s fuel efficiency regulations have been in place since 2018. China will shift to China VI in 2 phases—2020 and 2023; Phase 3 fuel efficiency regulations will be implemented in 2023.

These regulations will augment the penetration of advanced aerodynamics, low rolling resistance tires, auxiliary electrification, lightweighting, and advanced diesel engine technologies such as advanced turbochargers, automated manual transmission, advanced aftertreatment systems, and electrification.

Stringent emission regulations and government incentives are encouraging industry participants to explore advanced ICE engine concepts, energy recovery systems, and auxiliary electrification, including APU for operation on HVAC during vehicle standstill. The decoupling of auxiliary loads such as pumps for fuel injection and power steering, engine oil circulation, and air conditioning can reduce fuel consumption.
