DRIVERS FOR WEIGHT REDUCTION ------------------------- ROGER PRATT LAND ROVER GAYDON
Main Drivers for Weight Reduction • CO2 / Fuel Economy • Performance • Regulated Tailpipe Emissions • Vehicle Dynamics • Increasing Feature Content
AECA Commitment -25% from 1995 1995 Datum ACEA Monitor Point -10% from 1995 European Commission Long Term Objective -35% from 1995 1995 2003 2008 2012 CO2 Trendline Assumptions European Union
CAFE Standard ? Fuel Economy in mpgUS US Fuel Economy SUV Fleet Average Aspirations “Ford Motor Company Will Improve its SUV Fleet Average Fuel Economy 25% By 2005“
Performance vs Weight • Rule of Thumb Assumptions for 10% weight reduction: • MeasureImprovement • 0 - 100 km/h 7.0% to 9.0% • 80 - 120 km/h 9.0% to 9.5%
Regulated Tailpipe Emissions vs Weight • Weight reduction will help meet future • diesel emission standards. • Focused on large diesel vehicles EU4. • Small diesel vehicles EU5.
Vehicle Dynamics vs Weight Weight management plays an important role in: • Centre of Gravity • Front and rear weight distribution • Braking performance
Summary • CO2 is the new development that will increase the priority of weight reduction. • Customers do not want low weight vehicles, only • the attributes that low weight delivers. • Vehicles are very costly to produce and it will not be possible to sell low weight. • We must provide very cost effective low weight solutions.
