If you have a super sports
car, you need to have responsiveness, good sound, and you don't need to have a
high level of torque
at low
rpm.
Some of the key principles of Eco-Driving are: • Maintain engine speeds between 1200 — 3000 rotations per minute (
RPM); • Change to
higher gears between 2000 — 2500
RPM, and drive in top gears
at lower speeds — the so - called «50 in 4th gear» driving style; • Try to anticipate more to avoid strong accelerations, decelerations, overtaking or aggressive driving; • Driving
at speed limits and avoiding
high speeds; • Add 10 % to standard tyre pressure; • Avoid using the air condition, or set
at temperatures above 21Â °C; • Use your bike for short trips — starting your
car when it is «cold» uses 300 % more fuel.»
