Q&A

• Why are combustion engines still preferred over electric cars?

  Combustion engines are preferred for their convenience, especially for those without access to charging infrastructure. Electric cars are more logical for families with multiple cars and a garage. Low electric car adoption rates also limit their impact on fleet emissions, highlighting the valid reasons for combustion engines to continue existing and being improved.

• Why do car manufacturers prioritize improving internal combustion engines over investing in electric cars?

  Car manufacturers may find it more profitable to improve internal combustion engines due to market demand, emission reduction potential, and consumer preference. Investing in electric cars may only impact a small percentage of sales, resulting in limited overall emission reduction, thus influencing industry decisions.

• Why are electric cars currently more expensive to purchase compared to combustion engine vehicles?

  Electric cars are more expensive to produce due to lower demand and economies of scale. However, the high initial purchase price is not the primary reason for low adoption. Emotional factors and profitability for manufacturers play a significant role. Manufacturers prioritize combustion engines for higher profitability, influencing the cost difference.

• Why are lithium-ion battery packs challenging for larger vehicles like planes, trains, and trucks?

  Lithium-ion battery packs are significantly heavier and less space efficient compared to the energy they provide, posing challenges for use in larger vehicles due to space and weight constraints. However, advancements in battery technology aim to reduce size and weight, making electric cars the most feasible option.

• What is the energy density comparison between gasoline and lithium-ion batteries?

  Gasoline has significantly higher energy density per volume and weight compared to lithium-ion batteries, making it more efficient for cars. In 2018, gasoline was 13 times more energy dense per volume than lithium-ion batteries and about 50 times lighter for the same amount of energy.

• Why should combustion engines be improved?

  Improving combustion engines is important due to their potential for further enhancement and the challenges facing electric cars in various aspects like energy density, battery capacity, cost, and consumer preferences.
