0-60 Time Testing - Does The Downhill Grade Matter? In my 0-60 time pulls I typically record the acceleration at an on-ramp which has a slight downhill grade. In order to see how much this affects my times, I decided to run a test. Based on this testing, my times are accurate with 4-5%, which is pretty good considering weather, traction, and shift times could easily account for a 5% difference. I'm not aiming to post the worlds most scientific, fastest, and definitive 0-60 times, rather just something that can be used as a ballpark figure for a car's acceleration. I chose to use the 2016 Mitsubishi Outlander SEL S-AWC to run this test for three main reasons. 1. The vehicle has AWD so I do not have to worry about wheel slip interfering with the 60 times. 2. The vehicle is low powered, so the 60 time will be long, allowing for better accuracy in determining a difference in times. This also helps prevent wheel spin. (166 HP I4 Engine) 3. The vehicle has a CVT transmission. This will eliminate any shift time bias that could result from other transmission styles. Effect Of Gravity: Because the vehicle is slow, gravity will have a larger impact on the time than if the vehicle accelerated more quickly. Imagine a car on a downhill slope. You start timing, but don't touch the gas at all. Eventually, the car may roll to 60 mph if the incline is steep enough and air/friction resistance is low enough. Here, gravity accounts for 100% of the 60 time. Now imagine the same scenario, but with a very fast car. It accelerates to 60 mph in 4 seconds. Gravity has played a very small role (as a percentage) for this car to accelerate. Hence, slower cars will have a greater impact than faster cars based on the slope of this on ramp.
