No, in every cathegory the EURO5 emission levels are more stringent then EURO4.
For example, at Diesel Passanger Cars, PM level is 0.025 g/km (EURO4) and 0.005 g/km (EURO5)
Emission measurement methods might have been modified as well.

Hybrid cars have substantially lower exhaust emissions than normal cars and are better for the environment. Hybrid cars of all types get much better mileage per gallon of gas than normal cars.
speed - yes range - yes comfort - yes looks - yes emissions - no
Electric cars dont produce harmful emissions
It is better to pay highly now to reduce carbon emissions than to pay even more highly in decades to come because of our failure to take action. That is the choice.
Soybeans are better for the soil than corn.
Biodiesel improves public health and the environment, and provides safety benefits. It also reduces greenhouse gas emissions better than gasoline, ethanol, and conventional diesel.
Coal is not better than other energy sources. It is easy to dig up and cheap, if the company does not pay a carbon price, but it emits vast amounts of carbon dioxide which is causing global warming.Of the fossil fuels, natural gas is better than oil, and oil is better than coal, regarding their CO2 emissions, but they all pollute.Any renewable energy source is better, solar, hydro, wind, tidal, wave, geothermal and biofuel.
Electric cars have no emissions and are cleaner than conventional and hybrid cars because they produce zero pollution. They also are much more fuel efficient and get better milage.
No
Coal has more carbon dioxide emissions than either oil or natural gas.
motorcycles get better gas mileage than cars(gasoline), and therefore use less gas, which in turn does produce less carbon emissions. (if you drive a car and a motorcycle the same distance)
Solar powered cars are completely pollution free. They have no carbon dioxide emissions. They make no contribution to global warming. They are much much better for the environment than regular cars burning oil.
