FRONT WHEEL DRIVE
FF stands for front
engine/front-wheel drive.
Most cars are now front-wheel drive. Rear-wheel drive used to be most common among passenger cars, but
front wheel drive offers the advantage of eliminating the drive-train mechanism necessary to transmit the driving force from the front-mounted engine
to the rear wheels. The drawback of front-wheel drive for a sports car is
that the engine and drive train mechanism get concentrated in the front of
the car, making the car nose heavy and creating an unequal
weight distribution between front and rear. The front tires then have the responsibility of both steering and
accelerating braking, making it difficult for
sports cars to maintain ideal weight balance.
However, front-wheel drive has come a long way and has even been used
in some race cars. A good example of the advance in front-wheel drive
technology is the Honda Civic hatchback,
which delivers impressive performance and is capable of outperforming second-tier rear-wheel drive sports cars. Something to be careful about with front-wheel drive is that it's easy
to induce understeer. If you continue to understeer throughout
a race course, the front tires will
become very hot and begin to lose their traction. Thus it's important to master the proper steering and acceleration techniques.
Some other advantages to front-wheel drive include, decreased tendency to spin, and better traction on wet surfaces.
FRONT ENGINE
REAR-WHEEL DRIVE
FR stands for front engine rear-wheel
drive.
With
its weight-balance advantage, rear-wheel drive remains a popular choice for sports cars, Although most cars today have front-wheel drive, rear-wheel drive still offers a big advantage in weight balance.
In addition to having a nearly ideal 50-50 weight distribution between front and rear, the rear-wheel
drive uses the front tires for steering and the rear tires for accelerating and
braking. This divides responsibility between the front and rear, putting all four
tires to good use. This
gives rear-wheel drive a huge advantage in handling
and control. It offers the greatest room for Improvement in driving,
and maneuvers such as drifting become possible. If you've mastered the fundamentals of driving, rear-wheel drive
gives you the ability to control the car at will, leading to a more enjoyable
driving experience. By using all four tires
evenly, you
also decrease the chance of one tire overheating during long continuous driving. Other advantages of rear-wheel drive Include the absence
of sudden changes in handling and very slow drop-offs in speed.
MID-ENGINE REAR-WHEEL DRIVE
MR stands
for mid-engine rear-wheel drive.
Positioning
the heaviest part of the car, the engine, near the car's center, maximizes the car's cornering ability. As anyone who has seen a Formula One race car knows, cars built
for
speed have their engines mounted in the middle. With the front of the car
relatively light, steering becomes very sharp and direct. Because the engine is
near the rear axle, power from the engine gets transmitted to the road with
little wasted energy. Mid-engine cars also
have a high resistance to losing
control even during hard braking. Although mid-engine cars offer many advantages, they
are difficult
to drive. Mid-engine cars demand a mastery of fundamental driving
techniques such as weight transfer. Although they have excellent cornering
characteristics, it's easy to become nervous about the consequences of making
a mistake during cornering. If you master the advanced driving techniques, you'll be amazed
at the speeds you can reach with a mid-engine sports car. For
experienced drivers, mid-engine Is definitely
the way to go.
FOUR-WHEEL DRIVE
Every car has four wheels, not every car uses them equally
It's more efficient to transfer the engine's
power to four wheels rather than two. Although in the old days a car had either front-wheel brakes or
rear-wheel brakes, today all
cars come equipped with four-wheel
brakes. Cars today equipped with four-wheel drive deliver good traction even on slippery surfaces such as snow and other bad road conditions. Four-wheel drive is effective for sports cars that run on paved
surfaces or dirt, and it is used almost exclusively in rally
racing. There are also sports cars in circuit racing and mountain pass racing that use four-wheel
drive. Four-wheel drive becomes more effective with more powerful engines.
One drawback behind four-wheel drive is the complicated mechanism necessary to distribute power evenly to all four wheels and to keep
the wheels synchronized during cornering. This is particularly troublesome
in cars that have a tendency to
understeer.
But recent advances in four-wheel drive technology such
as electronic control have increased handling performance
considerably. This performance coupled
with the traction offered by four-wheel drive creates a powerful combination. On wet surfaces, four-wheel drive
clearly out performs two-wheel drive and even offers performance equal to mid-engine/rear-wheel drive.
