In america, cars get better mileage than the official numbers. I think this is because they test it with the AC running nowdays. It was one of the gimmicks the government came up with to force cars to get better mileage without changing the official CAFE requirements.
Werner Karl Heisenberg figured this out quite a while ago.
All i know is the wife and I went 3-4 years with only one vehicle since my work was so close to home. Got a new job a few months ago that is about 50 miles away. With gas prices and distance we decided to get a prius. No regrets they advertise 48/49 mpg. I’m averaging 52-56 depending on how quickly I accelerate - which is usually based on traffic at the time. With prices the way the are I couldn’t be happier.
Oh and we saved on insurance during those 3-4 years and put all that money back and scrimped and saved in other places rather then spending it. We paid flat for the car up front - no loans to worry about or be held over our heads.
Thank you Jesus for having our government regulate the shiite of these cheaters!
Hmm. They must run these tests at idle then, because the turbo these days kicks in very early - ~1500rpm or so. With VTG turbos etc. the days of "turbo lag" are long gone. Sounds like more BS "journalism". On the open road my Audi A4 quattro with the 2 liter turbo gasoline (200 hp) engine is close enough to what Audi states. And any sane person knows that stated figures are always a bit optimistic vs. actually driving in traffic. (I can get even better mpg than stated, but that takes the fun out of driving...)
Full sized 60s pre-smog cars got much better mileage than today’s hightech econoboxes.
How about filling the tank with fuel, driving it until the fuel gauge indicates it is prudent to refill the tank, then dividing the total distance driven since the last fillup, by the amount of fuel needed to again top off the tank?
Seems like a pretty reliable indication of the mileage potential. In real time and in real conditrons.
Years ago, Mobil held a “Grand Canyon Economy Run”, which provided just such figures on a real driving course, all vehicles in direct competition, following the same road and driving conditions.
Studebaker Champions came up with some pretty impressive numbers. And this was back in the late 1940’s and early 1950’s.
The truth is that the figures are only useful for comparison purposes. No set of testing can come even close to a real-world scenario.
