ATF Market Trends02-28-03© 2009 The Lubrizol CorporationAT116--001 11. Market Trends of ATF Market Drivers• Fuel economy • Transmission requirements becoming more demanding − Increased driver comfort & reliability • Reduced maintenance costs − Fill for life fluids05-21-07© 2009 The Lubrizol CorporationAT116-042 12. Market Trends of ATF CAFE Cost to OEM• Heightened pressure to increase lightduty CAFE − CAFE is sales –weighted average fuel economy rating − 27.5 mpg for passenger car * − 22.2 mpg for light duty trucks * • Each 0.1 mpg over CAFE limit carries $5.50 fine per vehicle 1.0 mpg…..$55 per vehicle * * www.nhtsa.dot.gov 08-12-08© 2009 The Lubrizol CorporationAT116-043 13. Market Trends of ATFFuel Economy Contribution of AT ••10-30-08Design a more efficient transmission − Lighter − More aggressive lock-up (ECCC) − Utilize a lower viscosity fluid Operates at its most efficient gear ratios − 6 & 7 Speed transmission − CVT or IVT − AMT − DCT© 2009 The Lubrizol CorporationAT116-044 14. Market Trends of ATF Low Viscosity Fluids• Typical ATF − 7.0 – 7.5 cSt @ 100° C • Low viscosity ATF − 5.5 – 6.0 cSt @ 100° C • Theoretical Gain = 0.1 mpg • Small change for driver, but significant for CAFE08-12-08© 2009 The Lubrizol CorporationAT116-045 15.
