How fast can a Town & Country go?
The 3.8L engine used from 1998-2000 puts out 180 HP at 4400 rpm. At 110 mph in 4th gear with the torque converter locked, the engine would be spinning at about 3300 rpm, putting out closer to 150 HP since at its torque peak of 3100 rpm it will put out 240 ft-lb of torque. Assume a Cd of approximately 0.35 and a frontal area of 31 sq ft. Also assume reasonable losses from rolling resistance (Cd = 0.015), driveline, accessories, etc. and flat level ground, and calm wind. Oh and air conditions at STP. Based on the equations, you’ll probably end up with a result of a maximum speed somewhere in the neighborhood of 110 – 115 mph. Do the calculations yourself. I went through many semesters of college and paid many thousands of dollars to get my mechanical engineering degree. If you’re a good engineer like I am and make proper assumptions and are careful in your calculations, you’ll likely end up within about 3% of the real-world empirically derived value. I’m not going to stifle your independ
