GM to Offer Stop-Start on Most of Their Lineup By 2020
William Maley posted an article in General Motors
General Motors is planning to expand the use of start-stop systems across most of their range by 2020 in an effort to improve fleetwide fuel economy. The plan will see at one powertrain combination offered in a vehicle to have this system. Stop-start systems work by turning off the engine when the vehicle isn't moving. When the driver removes his/her foot from the brake, the engine will kick back on. This move comes as the EPA will start handing out credits towards compliance with corporate average fuel economy standards to automakers who use this system in their vehicles next year. "Everyone will end up adding start-stop. Now there's a benefit in the EPA cycle, which there wasn't a few years ago. GM's new nine- and 10-speed automatic transmissions have been engineered from the beginning to incorporate start-stop. That will make it much easier and much smoother. That's what's been the holdup. First it was a regulatory issue, then it was a hardware issue," said AutoPacific analyst Dave Sullivan. GM spokesman Tom Read tells Automotive News that vehicles equipped with the stop-start system will use absorbent glass mat batteries (AGM) and tandem solenoid starters to enable faster and smoother restarts.
