Arguing against pursuing higher maximum speed through body shape experiments, instead prioritizing acceleration and weight reduction.

re. VARIOUS SUGGESTIONS FOR OBTAINING
HIGHER MAXIMUM SPEED.

Although I have every sympathy with this I think
we should continue to make maximum speed a 3rd. or 4th.
consideration to the good qualifications of our cars.

Under the heading of performance we think acceleration
(without an extremely low gear) to be one of the most important
qualifications.

Now acceleration is largely dependent on low speed
torque, and especially on keeping the weight down, and I
think that it is no use spending money on body and wing
shapes as we can judge very much within the range of possi-
bility whether a pattern is better or worse. The limitations
for capacity, comfort, appearance, and weight, are so well
defined that we cannot pass into a novel field for the sake
of wind resistance, which would affect maximum speed only.
If it had a chance of improving the riding qualities, or
acceleration, the subject might be worth while; but as far as
I can see at the moment I think we have other more important
things to absorb our time and money.
