Hybrid vehicles can offer more flexibility to some users with very high mobility needs. However, as far as CO2 emissions are concerned, hybrid vehicles are not an alternative to pure electric vehicles.

The pollution measurements of plug-in hybrid vehicles are carried out in a laboratory. These tests are extremely unrealistic, as reported by the European organization « Transport & Environment ».

Once the battery is drained, it becomes a dead weight, which increases the vehicle’s fuel consumption. For example, the BMW X5, which was tested in the laboratory with 32 g CO2 per km, actually consumes 385g CO2 per km under real conditions!

If you want to buy a rechargeable hybrid vehicle to reduce your carbon footprint, you should think carefully about your usage pattern. (You can use the CARBONCOUNTER developed by the MIT Trancik Lab to compare your favorite models.)
