Delphi Automotive has unveiled a 48V vehicle solution that could prove pivotal for auto makers in meeting future emission regulations without sacrificing performance for customers. The company confirmed it is working with two major OEMs and the system could see production within 18 months.
Showcased in a Honda Civic 1.6-liter diesel (above), Delphi’s 48-volt, mild hybrid technology enables “intelligent” electrification. The customized vehicle architecture maximizes the use of the 48-volt electrification to minimize the demand on the engine, improving performance while lowering CO₂ emissions by more than 10%.
“This is not only a significant step forward with reinventing the electrical architecture for dual voltage capability, it is also a triumph of software,” said Jeff Owens, Delphi’s chief technology officer. “This intelligent approach to vehicle power, wiring and data management will not only improve fuel efficiency, but will also enable a world-class driving experience while providing additional power for active safety systems and increased connectivity in the car.”
The system allows OEMs ‘ample room’ to innovate without increasing engine sizes to get more power. This technology leverages what engineers call an “e-charger” for improved vehicle launch. Delphi’s demonstration vehicle increases low-end torque by an average of 25%.
“Car buyers will buy 48V, mild hybrids for the added performance and car companies will offer the technology because it will help them comply with environmental regulations,” continued Owens. “One out of every 10 cars sold globally in 2025 will be a 48V, mild hybrid. To put that into perspective, that’s 11 million units a year – three times the volume of pickup trucks sold annually and more than half of the world’s anticipated diesel passenger car market.”
From an environmental viewpoint, the savings have great potential. It is estimated that 11 million 48V, mild hybrid vehicles would reduce oil consumption by four billion gallons (more than 15 billion liters) over the life of the fleet. As for greenhouse gas emissions, it would have the same effect as conserving 124 million barrels of oil or not burning 57 billion pounds of coal, according to the DOE.
