A detailed research agenda for CO reduction is discussed based on three different time frames as short term,
2
medium term and long term duration. Table 4.1

TABLE 4.1 VEHICLE WEIGHT REDUCTION, MATERIAL AND DESIGN ASPECTS

Drag reduction from form
Reduced use of steel BIW in changes
vehicle construction
SHORT MEDIUM -----------------------------------
TERM ----------------------------------- TERM
(1-5 YEARS) (5-10 YEARS) Active aerodynamics for losses
Increased use of aluminum, reduction
lighter alloys and plastics
----------------------------------- -----------------------------------
Weight reduction of seats, glazing Small light weight vehicles for
urban usage
and interior components
----------------------------------- -----------------------------------
Reduction in tyre rolling losses Larger low drag vehicles for
trucking
-----------------------------------
Drag reduction through fit and
finish and styling details
----------------------------------- Change in vehicle usage/
LONG
Introduction of structural TERM ownership patterns allows
composites (10-15 YEARS) specialization of vehicle design
