| Graph 1: The MOTOR 3/3/25. ROAD SPEED M.P.H. TIME SECS. BENTLEY SPEED MODEL. THIS THE VELOCITY CURVE CONSISTS OF TWO STRAIGHT LINES JOINED TOGETHER BY A CURVE. THIS IS MOST IMPROBABLE. Graph 2: The MOTOR 17/3/25. ROAD SPEED M.P.H. TIME SECS. VERMOREL 12-25. THE VERMOREL, LIKE THE RENAULT, APPEARS TO HAVE A CONSTANT ACCELERATION FROM 10 TO 53 M.P.H. WE HAVE SHOWN WHAT SORT OF A H.P. CURVE THIS NECESSITATES. | ||
