Altro che 2035, se va bene nel 2030 non ci sono più i pezzi per costruire ICE.

 

Non preoccupiamoci troppo, ce li forniranno gli indiani.

This report finds that the United States can achieve zero emissions transportation while limiting the amount of lithium mining necessary by reducing the car dependence of the transportation system, decreasing the size of electric vehicle batteries, and maximizing lithium recycling. Reordering the US transportation system through policy and spending shifts to prioritize public and active transit while reducing car dependency can also ensure transit equity, protect ecosystems, respect Indigenous rights, and meet the demands of global justice.

EPA proposes its strictest-ever vehicle emissions limits for 2027-32
The plan could lead to EVs making up 67% of new light-duty vehicle sales and 46% of medium-duty vehicle sales in the 2032 model year, according to EPA projections.
April 12, 2023 

WASHINGTON — The EPA on Wednesday unveiled its strictest-ever limits on vehicle tailpipe pollution, a regulatory move that could spur greater sales of electric vehicles in the U.S.

The proposed vehicle emissions standards cover the 2027-32 model years for light- and medium-duty vehicles. Coupled with federal incentives and other investments, they could accelerate the ongoing transition to EVs while clamping down on harmful pollutants in the transportation sector, the nation's largest source of greenhouse gas emissions and a main cause of air pollution.

Under the proposal, EVs could make up 67 percent of new light-duty vehicle sales and 46 percent of medium-duty vehicle sales in the 2032 model year, according to EPA projections.

"By proposing the most ambitious pollution standards ever for cars and trucks, we are delivering on the Biden-Harris administration's promise to protect people and the planet, securing critical reductions in dangerous air and climate pollution and ensuring significant economic benefits like lower fuel and maintenance costs for families," EPA Administrator Michael Regan said in a statement.

"These ambitious standards are readily achievable thanks to President Biden's 'Investing in America' agenda, which is already driving historic progress to build more American-made electric cars and secure America's global competitiveness," he added.

The EPA said its proposed standards are expected to save consumers $12,000 over the lifetime of a light-duty vehicle compared with a vehicle not subject to the new tailpipe pollution limits.

For light-duty vehicles, the emissions standards would increase in stringency each year, resulting in a fleetwide average greenhouse gas emissions target of 82 grams of carbon dioxide per mile in the 2032 model year.

For medium-duty vehicles, the standards also increase in stringency and are projected to result in an average target of 275 grams of CO2 per mile by the 2032 model year.

The proposal would require a combined fleet year-over-year CO2 reduction of 18 percent in the 2027 model year; 13 percent in 2028; 15 percent in 2029; 8 percent in 2030; 9 percent in 2031; and 11 percent in 2032. That equates to a combined fleet average year-over-year CO2 reduction from the 2027 to 2032 model years of 13 percent.

In comparison, under the rule for 2023-26 model-year vehicles, emissions standards increase in stringency between about 5 and 10 percent each model year. The standards mandate an industrywide target of 161 grams of carbon dioxide per mile — or 40 mpg on window stickers — by the 2026 model year.

The EPA said its proposed light-duty standards in the 2032 model year could lead to a 56 percent reduction in projected fleetwide average greenhouse gas emissions target levels compared with the 2026 model year standards. For the medium-duty standards, the reduction is projected to be 44 percent.

The proposal for light- and medium-duty vehicles also is expected to prevent 7.3 billion tons of carbon dioxide emissions through 2055, "equivalent to eliminating all greenhouse gas emissions from the entire current U.S. transportation sector for four years," the agency said.

While the light-duty standards continue to be based on vehicle footprint, the EPA is proposing to revise the vehicle footprint curves "to flatten the slope of each curve and to narrow the numerical stringency difference between the car and truck curves," according to the proposal.

It is also proposing to revise certain compliance flexibilities, including fully phasing out the off-cycle credits program — which allows automakers emissions credits for technologies such as stop-start engines and high-efficiency headlamps — by the 2031 model year and limiting eligibility to internal combustion engine vehicles.

Also on Wednesday, the EPA issued its Phase 3 proposed greenhouse gas standards for heavy-duty vocational vehicles, such as delivery trucks and school buses, that complement criteria pollutant standards finalized in December. That rule covers the 2028-32 model years and revises certain standards for the 2027 model year that were established in a Phase 2 rule.

Through 2055, the EPA projects the proposed standards for light-, medium- and heavy-duty vehicles would prevent nearly 10 billion tons of CO2 emissions.

Solo un'ONG Californiana può pensare di ridurre il traffico privato negli US come soluzione del problema. In Alabama la prenderebbero a fucilate dal cassone dei loro pick up 😜

Volkswagen contro gli e-fuel dell'Europa: "distrazione inutile, il motore endotermico è finito"

[4200blu]

E chiaro che nessun OEM ha interessa di mantenere a vita macchine ice in parallelo per un percentuale bassisima del volume totale eccetto qualche produttore di nicchia come Porsche con la 911 oppure Ferrari per le V12. Non e finanziabile a lungo termine. Il motore ice con tutte le sue complicazione come cambio ecc. e morto per i produttori di volume. Forse restera per il assoluto top end come agli orologi una „Grande Complication“ ma sicuramente non piu.

Vero, ma solo fino a quando le vendite avranno cali a due cifre. 

Poi assisteremo ad una ritirata al cui confronto Napoleone in Russia era un dilettante. 😜

Porcate con il diesel le han fatte tutti, chi più chi meno, perché a far le cose fatte bene avrebbero aumentato troppo i costi e ridotto troppo i profitti, come poi è avvenuto con la progressiva scomparsa dei diesel.

 

Il dieselgate semmai è servito proprio a dimostrare il limite della tecnologia. L’unico modo per salvare gli ICE è stata l’introduzione dell’ibridazione, ovvero l’aggiunta della componente elettrica, che ha aggiunto costi e complessità.
