Let's have a little torque

You must be of some distinction,
Have a certain savoir faire,
Be quite fine in your refinement
With a knowledgeable air -
To argue heatedly
On types of anti-freeze,
To have RPM and RPH
Roll off like ABC's,
And most especially,
To talk of torque with ease -
And to know the difference twixt
A VB and V6,
Carbohydrates, carburettor -
And Grand Prix and grand pricks.
