How We'll Get To 54.5 Mpg By 2025

concealment writes "At the end of August this year, the US Department of Transport's National Highway Traffic Safety Administration (NHTSA) and the US Environmental Protection Agency (EPA) announced new standards to significantly improve the fuel economy of cars and light trucks by 2025. Last week, we took a look at a range of recent engine technologies that car companies have been deploying in aid of better fuel efficiency today. But what about the cars of tomorrow, or next week? What do Detroit, or Stuttgart, or Tokyo have waiting in the wings that will get to the Obama administration's target of 54.5 miles per gallon (mpg) by 2025?"

Not anti American

[AdmV0rl0n]

I'm a Brit. I understand the tradition, and history of US cars, and that this holds a place for many American people. But your business and political angles don't work well for you here. Most of the US car makers already make fuel efficient engines and models for other parts of the world. I don't know if its parts of the US car industry and some political levels that are messing around - but they should stop.

At some stage the US will face a fuel hit. It would be much better to have the things lined up than be caught out. Your citizens should not face that having mistakenly bought high fuel consumption models after being decieved or lied to by car makers or political fools. The car is central to life in the US. The fuel munching car has no real future in this.

Americans can always be counted on to do the right thing.

After they've exhausted all other possibilities.

A poorly designed merge section from one highway to another is what convinced me I needed a quick car.
It isn't safe merging into 60+ MPH traffic at 30 MPH. Top speed typically isn't a problem but acceleration on cars with wimpy engines is.

I drive 40+ miles to work each day. I am about to drive 250+ miles to meet with a customer. America is not as densely populated as Europe. Cars are how we travel. This is why we won't buy the small cars that are popular in Europe.

This is rubbish, the average commute is rather short and comparable on both sides of the pond, and I regularly drive straight through France and Germany. We too drive a lot.

The real reason why large cars don't sell and small cars do sell in Europe is because of the insane gas prices. When you pay $10/gallon you will change your driving habits or your type of car.

I just got myself a new car which is quite large for European standards, it goes 40mpg which is decent. But more and more commuters are going for efficient smaller cars (50-60mpg) because of increasing fuel costs, the difference means that the car pays for itself within a few years.

If fuel costs were the same I'd bet every family here would want an SUV too.

And acceleration despite a relatively wimpy engine is on major problem that hybrids are designed to tackle. The electric motor isn't enough to drive you very far or very fast on its own, but combining the power of the relatively wimpy internal combustion engine with the power of a relatively wimpy electric motor gives you enough power to merge onto a freeway or go up a steep hill with some confidence. When you don't need that extra power, the relatively wimpy engine is well chosen to give you good fuel economy at highway cruising speed.
