Powertrain systems

The Powertrain Systems Business Group develops and manufactures innovative powertrain solutions designed to reduce CO₂ emissions and fuel consumption, without compromising driving performance or pleasure. These innovations revolve around three approaches designed to meet and anticipate global market trends:

  1. Electrification– from the optimization of internal combustion engines to any  level of vehicle electrification, from the Stop-Start system – a Valeo pioneer innovation, to the electric powertrain systems for the electric cars
  2. Transmissions automation– for an improved driving comfort through solutions for all automatic gearboxes, from automated manual to dual clutch transmissions. The product range was extended to active actuation systems for transmissions following the acquisition in 2017 of FTE automotive.
  3. Clean engine– solutions for air loop management to reduce emissions and optimize engine efficiency

Powertrain Systems Product Overview

I – Electrification

Valeo offers the full portfolio of customizable solutions for any level of electrification and vehicle segment, from low voltage mild hybrid to high voltage full electric driving. The latter is managed by the Valeo Siemens eAutomotive joint venture.


12V and 48V Mild Hybrids – The access to hybridization for volume segments

A Hybrid car is characterized by an electric support in the internal combustion engine that helps it to consume less fuel.

Valeo invented the Stop-Start system in 2004. It is a 12V Starter Generator that turns off the engine when it’s not necessary: traffic jams, red lights, for instance. This avoids wasting energy thus fuel economy and CO2 emissions. We have improved this solution to enter this hybrid world through two new offers.

Beyond 60V – High voltage, high-end solutions

II – Transmission Automation

Transmission automation is a growing global trend with technologies like automatic transmissions, automated manual transmissions and dual clutch transmissions.

Valeo, an innovative pioneer in this field, offers several product ranges enabling the automation of transmissions to reduce fuel consumption and improve driving comfort.

Range of clutches for all automated gearboxes

Dampers – Solutions to eliminate noise and vibrations for all transmissions

III – Clean engine

This approach specializes in efficient solutions like air circuit management for air intake and exhaust that reduce CO₂ and gas emissions, while enhancing the driving experience and engine performance.
