Update, , , , (We got a new 2016 Honda Civic EX in August). 2 liter, 4 cylinder, VTEC Earth Dreams engine. I've had to make the trip to Deltona from Suntree lately, 144 mile round-trip; ECON Mode, I95, 46, 415, etc. Got back into the driveway last night: 46.8 miles per gallon round-trip (had seen up to 47.2 on the read-out). I am pleased.

Cruise control settings: I95 72MPH, 46 56MPH. 415 45 - 55MPH.

Oh, and, , , , daily driving on Wickham Road, US1, Pineda, A1A, etc, with no ECON mode, averages 32.5 with all of the stop-and-go.

31 "city", 41 "highway", 35 "combined" The lady I work with has the '16 EX-L with the 1.5L Turbo and she has been getting 48MPG!! She always has the ECON mode engaged and primarily drives I95 from 192 and then 520 to the Cocoa library (Cocoa water tower area).

Back in the 09's I had a '90 CRX HF model.  It routinely got 46-48 in mixed driving. If you had told me back then that kind of mileage would be considered expeptional in 2017 I would have laughed out loud.

But, that little CRX had a 1.5 liter engine that gave out only 62 horse power. The '16 Civic has a 2 liter that produces 158 horses.

It would seem, by extrapolation of those two examples^^,

that we would have some functional 100 mpg vehicles.

I know the physics argues against it, but still...

sigh.

^nice but a little dated

I wasn't up on MPG-e so I wiki-ed it (embarrasing right?)

and about 1/2 way down the page they have a 2016 list of EVs and their MPG-es.

Pretty impressive, 29 vehicles, 11 manufacturers repesenting most of the big name automakers

all at or around 100 MPG-e.

Getting there!

Yes indeed. And if I recall 3rd, 4th and 5th were all overdrive gears which made driving interesting. Around town it was pretty manageable but out on the highway at speed if you wanted to pull out to pass you had to have planned ahead for the time it would take to achieve passing speed or you'd really piss off those coming up on you in the left lane. 

 

Anyway, my point is that I thought we would be further along the road to maximizing efficiency by now given what we have achieved long ago.  It seems like most of the technological gains achieved over the past 20-30 years gave done toward satisfying our desire for more power which one can argue is not necessary.  I would think that as a country we would see maximizing efficiency as one of crucial priority areas of emphasis toward achieving energy independence.  Then again, for better of worse, I guess the free market makes that call for us.

My long-ago Geo Prizm (which I think is still in use somewhere around Rockledge) did about 40 mpg when driven from Portland, Oregon to Melbourne in 2000.  It was a Toyota Corolla hatchback, assembled at the joint Toy-GM plant in Fremont, California that made my current Vibe.

I had a '79 or '80 honda civic with a 1200 cc CVCC motor that got 40mpg way back when.

It was a deathtrap.

Every car has a sweet spot for mpg. Removing surf racks and maintaining tire pressure are huge helpers at highway speed. My old 1978 Datsun easily got 40 mpg hwy when the speed limits were 55.

Cool charts. I remember back in the 90s when friends were getting 40+mpg in their Honda CRX's. Probably just a function of weight and aerodynamics, but it's interesting how we're just now re-approaching those numbers on some similar cars. I'd rather be in an accident in today's cars, though.

How you drive is a HUGE determinant, too. I've gotten 36mpg on an extremely responsible, yet dull, highway drive, and 6mpg around Palm Beach International Raceway.

Anyone have an enormous Yukon or Suburban or something? What do those average in the real world?

I got about 19 mpg hwy in my old 5.7L 4WD Suburban, if I coaxed it. Was afraid to drive much faster than 70 because of the rollovers, and I had some of those bad Firestone tires for a while. Loved it when refilling the 44-gallon tank at $4/gallon!

I got 30 mpg hwy once in my 1986 5.0L Camaro, with 5-speed. At 70 mph, barely 2000 rpm. Decent aerodynamics, so not working much harder than idling!

My VW TDI Wagon only gets about 32 mpg around town. Aerodynamics are not great (surf racks don't help). Its sweet spot is probably 60 mph, but I have nowhere to drive long distances at that speed.

At 70 mph on I-95, it gets over 45 mpg, but I'm typically doing 80 and getting around 40.

I'm surprised we don't see more ECVT's (electronic continuously-variable transmissions); they've been around forever.

So, , , , what we know from the foregoing, , , , and this; the CRX has a "curb" weight of 1967 LBs and our Civic has a curb weight of 2795 LBs. Given "all-things-equal" in regard to mileage being same/similar, and considering the big differences between weight and horse power, , , , what would a "2017" CRX do in regard to mileage, with current tech and a 100 HP power plant?

The science makes sense on them, but man are they just gross to drive. Ever driven a Nissan with a CVT? There is no fun factor at all. That, and, from what I've heard, when a CVT on a Nissan breaks, it's so pricey to repair that sometimes the owner just junks the car.

About real world Suburban mileage, my '92 gets 15 mpg regularly (mixed driving) and 13 towing.  

Her service as a work vehicle has long since ceased and now she's purely a recreational vehicle.  

Ahhhh, retirement.  

Her, not me.
