GM Preparing to Make CVTs In-House

General Motors strategy to deal with rapidly tightening fuel economy restrictions is likely to include a new CVT developed in-house by the company.

Continuously variable transmissions are currently a part of GM’s repertoire, but only in limited applications including the Spark. Citing an unnamed source, WardsAuto reports that GM is in the late stages of developing a CVT that it will package with several high volume models by 2019.Later this year GM will roll out a new family of three- and four-cylinder engines that will eventually be mated to the new CVT. Wards reports that GM is currently hosting suppliers at its global powertrain headquarters in Pontiac, Mich to take bids for parts.

General Motors hasn’t officially announced plans for a new CVT, but IHS Automotive forecasts that a new GM-developed CVT will launch sometime between 2017 and 2018. “We expect the CVT to be used for small cars including Cruze, Spark, Trax and Sonic for the Chevrolet brand, as well as Opel products,” IHS senior analyst Stephanie Brinley wrote in an e-mail.

Automakers are hurrying to meet impending corporate average fuel economy standards that will require automaker fleets to average 54.5 MPG by 2025. In late 2013, Ford announced that it would include engine start-stop technology across 70 percent of its lineup by 2017, claiming the technology would offer drivers an average 3.5 percent fuel savings, but up to a 1- percent savings in some cases. Start-stop systems are most effective in heavy stop-and-go traffic where the car would otherwise be idling for long periods of time.
