Here’s an idiot formula for acceleration in a gear. This is probably stupid as it leaves out aero and tires, and weighting but a good rule of thumb for comparison. Lower = Slower.

(Final drive / Gear ratio (I like to use 1st))

————————

(Weight / Wheel hp)

For instance: 2014 Corvette C7 coupe M7

Final drive x 1st ratio = 3.42 x 2.66 = 9.0972

Weight: 3298 lbs

Wheel hp: Assuming 12.5% drivetrain loss = 398.125 hp

9.0972 / (3298 / 398.125) = 1.09818761370528

2013 Dodge Challenger R/T Auto = 0.87848214649681
