I hope you guys don't mind pedaling **cough, operator assist**

Next up, cars that run on fairy dust.

NHTSA can suck the left one.

By 2025 there will be a lot of electric cars, which get very high mpg equivalents.

Not without huge grid and power plant changes...

 

[IcePickFreak]

So in 2025 my monthly home electrical bill will be $1,200? (Adjusted for inflation deflation.)

Right now, you can expect to get 40 mpg with a compact. In 15 years I could see that reaching 62 mpg. I don't know if I had a family of four that I'd look forward to doing all my commuting in a compact.

Well by 2025 I expect engines to be even more fuel effecient. Now we have Ford Mustangs with 305HP V6's getting 29mpg on the highway, and this is just the first year of that motor. It's only going to get better. And that 300HP is plenty for a full size sedan.

29mpg is a LONG ways away from 62mpg. Hell, my motorcycle doesn't get that and it's not even huge (650 twin).

The left has none.

It's not close, but it shows we have come a long way, and with clever engineering it could be achieved.
And we don't need everything to have a 300HP V6.
These little sub 2L motors are starting to put out useable power for freeway use, and get 30-40MPG
If you think about it, 15 years ago, "econoboxes" were only making 100-120hp and getting 25-28mpg highway.

But instead of just engine design, thye need to look at ways of lowering rotation friction from wheel bearings and such.

Cars are making a lot more power now, but mileage hasn't improved a whole lot. New cars are heavy.

None of those cars would come close to today's emissions requirements either.

None of those cars would come close to today's emissions requirements either.

And, none of the safety requirements.
I can see a 5-15% increase in engine efficiency, but the bulk will come from the use of lighter materials, aluminum and carbon fiber. The costs will be high both in the purchase and for repairs. Expect insurance costs to rise accordingly.

since a typical car blows 75% of its energy out the tailpipe without doing anything, and brakes waste 100% of the remaining 25%, i'd say there's a ton of room for improvement.

There sure are, however improvements cost money.

How about we put nuclear reactors in cars and never put gas in them?

I don't think those first bits are quite right...

 

[Kelvrick]

They are if you hit the gas while on the brakes as well. As long as you don't actually move, 100% waste is achieved.

Yes a rinky dinky compact. They say for cars AND light trucks. That includes more than the super compacts that get that kind of mileage.

A lot of heat and water are being created. Electricity is being generated.

 

[DominionSeraph]

Whoa, y'all are a bunch of scaredy-cats.

The VW Rabbit diesel got 60mpg... in 1980. Engines have come a long way since then.

In 15 years I wouldn't be surprised if every passenger vehicle sold was a series hybrid with a ~300cc turbodiesel or GDI.

Umm that's diesel. Diesel engines don't sell well here in the States and it costs a lot more money to make diesel as low emissions as the government wants all cars to have which is why they are pretty much only on nicer cars. All that technology they have to put in the exhaust costs money.
