Factors affecting MPG

[HisenZhang]

Figure out how the following factors affect fuel efficiency (Miles per Gallon):

• inclined road
• cargo (and engine/power source) load
• current velocity

inclined road: for every 1% incline, car comsumes roughly an extra .4 gallons per 100 miles https://afdc.energy.gov/data/10601#:~:text=On%20an%20uphill%20grade%2C%20all,%2D3%25%20to%205%25.&text=Both%20conventional%20and%20hybrid%20SUVs,likely%20because%20they%20are%20heavier.

Cargo load: every 10,000 pounds of cargo makes you lose half a mile per gallon in fuel efficiency. https://www.imiproducts.com/blog/calculate-fuel-efficiency-gains/#:~:text=Going%20back%20to%20the%20Starship,half%20a%20mile%20per%20gallon.&text=The%20more%20cargo%20you%20haul,resulting%20in%20more%20fuel%20saved.

same applies to engine/power source

Velocity: ideal velocity for efficiency - 55 mph Fuel efficiency decreases after 55 mph https://www.mpgforspeed.com/#:~:text=Unfortunately%2C%20it's%20true.,is%20around%2055%2D60%20mph.&text=You'd%20be%20surprised%20to,minutes%20to%20your%20travel%20time.

According to FuelEconomy.gov, the 2018 Tesla Model S Standard Range requires about 31 kWh per every 100 miles https://news.energysage.com/what-does-it-cost-to-charge-a-tesla-with-solar-energy/

90kWh battery weighs 60lbs https://stealthev.com/product/tesla-6-2-kwh-module-from-90kwh-pack/

Tesla Solar Panel Specs: 315 W Dimensions 66.3" x 39.4" x 1.57" Weighs 44.5 lbs I did the math we can fit around 8 of these on the roof of the cargo van

This does not seem to be a good estimation.

Yeah you’re right that graph makes it look like for 3% uphill the truck van would consume around 2.5 extra gallons per 100 miles and for 3% down hill the van would consume around 1 gallon less per 100 miles.
