AUBURN HILLS, Mich.,
Sept. 21, 2015 /PRNewswire/
-- BorgWarner supplies Eco-Launch™ stop/start accumulator
technology and multi-segment wet friction plates for the new
8-speed rear-wheel drive automatic transmission (8L45) from General
Motors. To enable the transmission's stop/start functionality,
BorgWarner's Eco-Launch hydraulic accumulator and solenoid valve
provide rapid, quiet and smooth engagements during engine restarts.
BorgWarner's advanced friction plate technology reduces drag and
enhances shift feel. Improving fuel economy up to 5 percent
compared with similar 6-speed automatic transmissions, the 8L45
transmission will debut on the 2016 Cadillac CT6 and will also
drive the 2016 Cadillac CTS and ATS.
"BorgWarner's leading transmission technologies deliver seamless
shifts and smooth launches with the added benefit of improved fuel
economy," said Robin Kendrick,
President and General Manager, BorgWarner Transmission Systems.
"Collaborating with GM on our latest friction plate solutions and
ground-breaking innovations, such as our Eco-Launch stop/start
accumulator, puts new technology on the road quickly. We are
pleased to support GM in introducing another important transmission
technology to the market."
Stop/start systems increase fuel economy by turning the engine
off when the vehicle stops. For quick acceleration from the stop
mode, BorgWarner's accumulator and Eco-Launch solenoid valve
quickly re-prime the transmission in less than 0.3 seconds, the
time it takes the driver to switch from the brake to the
accelerator. The exceptionally low-noise, high-flow, low-leak
solenoid valve opens against large accumulator pressures and stays
closed against high line pressures. The technology earned
BorgWarner an Automotive News PACE Innovation Partnership Award for
its collaboration with GM as well as a 2014 Automotive News PACE
Award.
BorgWarner's multi-segment wet friction plate technology
features full-depth grooves cut between segments of proprietary
friction material. The groove patterns and material are engineered
for each specific application to optimize the clutch for low drag
which improves fuel economy, provides seamless shifts for better
performance and delivers durability that exceeds the life of the
transmission. Utilizing advanced processing capabilities and
intricate groove designs, BorgWarner's latest friction plate
technology is proving successful under a widening range of
operating conditions and offers the same benefits in torque
converter applications. This technology was first introduced on
GM's Hydra-Matic 8L90 in the 2015 Corvette Stingray and Z06, and
will now be featured in the new 8L45 automatic transmission for
various platforms.
BorgWarner produces its multi-segment wet friction plates in
Bellwood, Illinois, and its
accumulator and Eco-Launch solenoid valves in Water Valley, Mississippi. To meet growing
demand, BorgWarner is investing in both plants to improve
efficiency and expand capacity.
