196 Driving and en vironm ent
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avo id driving short distances with a
cold engine.
The engine and catalyt ic converter have to
reach their optimal
operat ing tempe ratu re to
reduce fuel consumption and noxious emis
sions effect ively .
Just after starting, a cold engine in a mid-size
car only achieves a fuel economy of 6-8 miles per gallon (30-40 l/100 km). After about a
half a m ile, fuel economy climbs to 12 mpg
(20 l/100 km) . After about
2 .5 m iles (4 km),
the eng ine is at its proper operat ing tempera
ture and fue l economy has reached a no rma l
l eve l. So you can see that you sho uld avoid
short tr ips whenever possib le .
The
o ut sid e temp era ture is also critical in this
r egard. Your car consumes more fuel in the
winter than in the summer.
