The Mid-Engine Advantages:
You have the choice of many 4 cylinder or V-6 front wheel
drive packages.
Allows for a light weight compact driveline.
A rearward weight bias improves acceleration and
braking.
The engine heat and exhaust doesn’t cook your
feet.
More foot room with no transmission or
driveshaft.
It's quieter with the exhaust behind you
Independent rear suspension rides better with
better camber control
No driveshaft tunnel means more seat/interior room.
Engine torque doesn't deform chassis.
The gas tank location is in the safest place and is at
the CG so handling doesn’t change with with fuel level.
With centralized mass it's easier to turn.
With the engine behind you have great
visibility.
