Why does fuel economy get better on the highway, but EV range gets worse?
In: 463
Fuel economy doesn’t really get better, it’s just less bad.
One liter of DIESEL contains an energy of about 10 kWh (sorry to all physics teachers if I use the wrong expression). Even the most advanced and “clean” Diesel cars need about 5 liters for 100km on the highway = 50 kWh. (and then there are many cars that even need 10-15 liters for 100km)
My EV needs exactly 20 kWh for 100km on the highway.
5 liters (=50kWh) of Diesel cost about 7.5€ in my country.
20 kWh charged to EV directly, cost me around 8€.
Find the reason why there are still so many ICE cars on the streets.
(I know the energy contained in Diesel can’t be converted 1 to 1 to kWh, I just want to show that even after 100 years, ICEs are still very inefficient and the last 10 years didn’t bring much progress which suggests we hit at wall at that part of development)
