Online trolls drive us crazy saying that our cars are big, heavyand that they drive like boats. Well, our solution to everything ismore horsepower. Even, in 1921, the Dodge Brothers built a boatnamed the SS Delphine and it had a whopping 3000 HP. So, how muchhorsepower would a Challenger SRT® Hellcat Redeye Widebody need totow the SS Delphine up the industry standard: Davis Dam GradeClimb?

Pro Tips
Davis Dam assumed grade = 7%
Air density is sea level conditions (.002377 slugs/f^t3)
w(weight) of the SS Delphine + trailer + Redeye = 3,922,000 +150,000 + 4451 Lbs
Crr = coefficient of rolling resistance = .015
Assume Combined CDA is 1555 ft^2
SAE J2807 (Davis Dam Grande Climb) - min speed is 40mpg (59ft/s)
F(drag) = 1/2p x V^2 x C(d)A
F(rolling resistance) = W x cos x Crr
F(weight) = W x sin
F(sum) = F(drag) + F(rr) + F(weight)
P = F(sum)XV
convert to horsepower = P(1hp/550ft lbf/sec)
