I've owned 3 automatics in 30 years. I'm going to ride out the apocalypse in my 2-seat 50+ year old, 35mpg manual.
35mpg is like 13l/100km. thats like really bad?
Edit: Lol its more like 9l/100km, still not great tho
Sadly, that's actually on the higher end of the spectrum when it comes to American vehicles
No wonder with all the trucks and SUV
1 gallon is about 3.8 liters. 1 mile is about 1.6km.
35 mi/gal = (35 * 1.6km)/gal = (35 * 1.6km)/3.8l
You want liters per kilometer tho, so reciprocal: 3.8l/(1.6km * 35)
To drive 100 km, you need 100 times the fuel => (3.8l*100)/(1.6km * 35) ~ 6.8 l/100km
I'm getting 6.7l/100 km using Google. Not sure what math you're doing. But keep in mind there are two different gallons, US and Imperial or something. 35 mpg is pretty normal for a gasoline-only car these days (hybrids can do better depending on driving conditions - if they can spend most of their time on battery, for example). Diesel cars aren't much of a thing in the US, again, especially after the whole Volkswagen cheating thing.
I know there used to be diesel cars in the 80s that would get crazy numbers like 50 mpg (4.7l/100km), and gas-powered cars probably could now, too, but emissions and safety requirements have pretty much killed that.
Yeah, doing the math I also get 6.7L/100km (assuming US Gal, which I presume is correct since they're using mpg). Also, looking at Wikipedia, it looks like the testing standards between the US and, say, the EU, can cause potentially a 1L/100km difference between the two, where the EU standards give a lower L/100km.
I really shouldn't do math in my head...
I looked up the 9ish, but not sure what calculator that was. I do get to 6.7 now too, so that is really not that bad.
I was starting to wonder what kind of cars you guys have that get such incredible fuel economy. :)
Yeah, but it's 50 years old. 12 was the average, and you really didn't see anything getting better that 25. That's on older roads with leaded gas and bias tires.
