The difference of three types of technologies: Internal Combustion Engine (ICE) car / Electric Vehicle (EV) / Plugin Hybrid Electric Vehicle (PHEV) and a comparison between three cars of year : Open Insignia / Nissan Leaf / GM Chevrolet Volt are presented in figure.

Electric cars have many advantages:

  • Great driving experience by low engine noise and very good acceleration by the large max. torque immediately at 0rpm,
  • High efficiency about 70-85% comparing to ICE (30-40%),
  • Electric motor and simple drivetrain (reducer one ratio), so more durable and lower maintenance cost,
  • Not dependent on oil,
  • No direct discharge of pollutants from the environment (including the environmental emissions by power plants produce electricity to charge the battery, the total rate CO2 emissions of electric cars is very low around 10-14 g/km).

However, the biggest obstacle of electric cars until now is the energy storage system. It means the ratio between the energy storage in battery pack and its cost, the charging time is quite long and the expensive cost while a little production.

Comparison of total cost between Nissan Leaf vs Open Insignia (purchasing price without the bonus/malus in France)

Restrictions on the range (175/950 km) and the charging time for battery charge / pump (6-8 hours / 5 minutes), even if with the bonus of the government, the current price of Nissan Leaf is 23 % more expensive than Opel Insignia. However, in addition to great driving feel, Leaf does not emit exhaust emissions on the environment pollution 0g compared with 1.74tons of CO2 of Insignia for an average of 15 thousand km per year. Less fuel costs, Leaf is also much cheaper 300€ than 2200€ Insignia in France, and also less maintenance costs. So regarding the total cost in 8 years (the duration of lithium battery pack warranty), Nissan Leaf will be more beneficial. Recently, the Nissan Leaf has touched 100 thousand vehicles sold worldwide since late 2010, accounting for 45 % market share of 100 % electric cars.
