The quest to reduce CO 2 The challenge for the automotive industry

Since 2000, the quest for reduced CO 2 emissions has led to the introduction of several new technologies. One of them is the Stop-Start; it automatically shuts down and restarts the engine to reduce the amount of time the engine is idling, thereby reducing fuel consumption and emissions. This is most advantageous if you spend a significant amount of time waiting at traffic lights or frequently get stuck in traffic jams. This feature is present in hybrid electric vehicles, but predominantly appears in conventionally-powered vehicles, so-called micro- hybrids.

All countries regulate now CO 2 emissions, triggering similar evolutions on powertrains all over the planet. From StARS (2003) to ReSTART (2010), i-StARS (2010), i-StARS-2nd generation (2011), i-StARS- 3rd generation (2017) and further generations and forthcoming 48V E-machines, Valeo develops solutions to cope with car makers targets.
