Performance vs Energy Consumption
Use adaptive propulsion and regenerative recovery to supply high power only on demand, preserving performance while cutting average energy consumption.

Regulations
Business Context
Customers expect strong acceleration, responsive vehicle dynamics, sustained high-speed capability, and increasingly sophisticated comfort and electronic functions. These characteristics require energy, while regulatory, environmental, operating-cost, and vehicle-range objectives demand lower energy consumption. Increasing propulsion capability can therefore increase fuel or electrical energy demand, while aggressive energy-saving strategies can reduce perceived performance or functionality.
Automotive TRIZ Resolution
Automotive TRIZ separates maximum performance capability from continuous energy consumption. High power does not need to be delivered under every operating condition. Adaptive propulsion control, regenerative energy recovery, predictive energy management, variable auxiliary operation, optimized operating points, and condition-dependent performance modes allow energy to be supplied according to actual demand. Vehicle-level efficiency improvements in aerodynamics, rolling resistance, thermal management, and mass can further reduce the energy required to achieve the same performance.
Applicable TRIZ Principles
Principle 15 – Dynamics adjusts vehicle and powertrain behavior according to current performance demand.
Principle 19 – Periodic Action provides high-energy operation only during periods when additional performance is required.
Principle 22 – Blessing in Disguise recovers energy that would otherwise be dissipated, particularly during braking and deceleration.
Expected Outcome
Lower overall energy consumption
Preserved peak vehicle performance
Improved driving range or fuel economy
More efficient use of available energy
Decision Indicators
Early indicators that this contradiction is limiting vehicle performance include:
Higher performance variants experience disproportionate increases in energy consumption.
Energy-saving calibrations noticeably reduce vehicle responsiveness.
High-capability systems consume substantial energy during low-demand operation.
Range or fuel-economy targets require repeated performance restrictions.
Significant braking or thermal energy is dissipated without recovery.
Monitoring these indicators helps determine where performance capability can be separated from continuous energy demand.
