Lani so malo omehčali rip 2035, zdaj pa očitno dokončno pokopali
Im EU-Parlament zeichnet sich eine Lockerung des Verbrenner-Aus ab. Neuwagen mit Verbrennungsmotor und Hybridantrieb dürften auch nach 2035 verkauft werden.

According to this plan, CO2 emissions from new cars in the EU are only to be reduced by 87.5 percent by 2035 compared to the baseline year of 2021. If this policy is implemented, manufacturers would be allowed to continue selling new cars with combustion engines and hybrid vehicles even after 2035 without risking billions in fines.
Emisije co2 za nova osebna vozila po 2035 (čez 9 let) bodo morala biti manjša za 87.5% glede na leto 2021 oz. bodo morala dosegati samo 12.5% od vrednosti iz 2021.
Prej je bilo sprejeto, da mora biti številka 100%, se pravi ice prepovedan.
Kako bodo za 87.5% lahko zmanjšali co2 ?
Ai, Gemma 4:
Reducing CO2 emissions by 87.5% is an extremely aggressive target that pushes internal combustion engines (ICE) toward their theoretical limits of efficiency. Because CO2 emissions are directly proportional to the amount of fuel burned, achieving this reduction requires a combination of extreme fuel efficiency, lightweighting, and a transition to carbon-neutral fuels.
To approach this standard, manufacturers typically focus on these technical adjustments:
**Advanced Combustion and Thermal Efficiency**
Manufacturers are developing higher-compression engines and leaner-burn cycles to extract more energy from every drop of fuel. This includes "cylinder-on-demand" technology to reduce displacement during low-load driving and sophisticated thermal management systems that reduce the energy wasted as heat. Hybridization is the most effective adjustment here; by pairing an ICE with a battery and electric motor, the engine can operate only in its most efficient RPM range, while the electric motor handles the high-emission tasks of idling and accelerating from a stop.
**Weight Reduction and Aerodynamics**
Since a significant portion of fuel is spent moving the mass of the vehicle, manufacturers are replacing steel with carbon fiber, aluminum, and high-strength plastics. Improving the drag coefficient through active aerodynamics—such as shutters that close at high speeds or seamless underbody panels—reduces the energy required to push the car through the air, thereby lowering the CO2 emitted per kilometer.
**Transition to E-Fuels and Biofuels**
The most critical "adjustment" for meeting a near-90% reduction is not how the engine burns fuel, but what fuel it burns. Traditional gasoline and diesel are carbon-positive. Synthetic "e-fuels" (produced by capturing CO2 from the atmosphere and combining it with hydrogen from renewable electricity) or advanced biofuels can be "drop-in" replacements. Because these fuels release only the carbon they absorbed during their production, the net CO2 emission of the engine can drop precipitously even if the mechanical efficiency remains the same.
**Downsizing and Forced Induction**
Continuing the trend of downsizing, manufacturers use smaller engines with high-pressure turbochargers and superchargers. This allows a small, fuel-efficient engine to provide the power of a larger one. When combined with mild-hybrid systems (48V architectures), these engines can shut off completely during coasting or braking, eliminating emissions during those periods.
Na kratko povedano: teoretično mogoče,v praksi neizvedljivo.
