Gas Mileage
 

i have seen 30mpg figures. and i expect this car to at least get 26-27MPG with DI, max 2800lb curb weight, and economical final gear ratio for 6SPD.

but this UK review says it expects it to get ABOVE 40MPG. wow

Even better. Lol 40mpg sounds prettttttttty awesome to me! lol

Must be a lot of downhill driving both ways in the UK lol

Imperial gallons are also larger than US gallons, with 1.2 US = 1.0 Imp.

Simply put, you can go 20 percent further on an Imperial gallon.

I'll be happy if it's better tan my RX-8!

32-33 highway does sound pretty accurate to me.

If that is the case their # should be even lower.

n/m brain fart

Nope, it's because our roads are made of a special tarmac that permits so much extra traction that it can vastly improve fuel consumption :-P

I'm guessing these are just estimates based on how the car is being driven, using the high gears on a motorway as opposed to country lanes etc.

I live 5 miles from work, I'll have to be doing some mad WOT if I want to show off the car at a gas station every now and then.

I will be hypermiling this car. Not gonna use any crazy advanced techniques either. If it will be rated at 30mpg, then expect me to post up low to maybe mid 50's.

I have a Prius :scared0016: for daily commuting and easily get 60+mpg combined on average (84mpg was my record this past summer) and its only rated for 46mpg.

Is hypermiling even worth it, including all the safety concerns?

Hypermiling isn't for this car... It's like people that buy a Vette try to squeeze 50mpg out of them (they do too)... Just not the idea behind the car you know...

This is suppose to be a car where you're encouraged to give it some throttle no matter what you're doing with it... The brakes are good too so they expect you to be coming in to a stop pretty hot...

This will be a DD for most people, but a DD where you're go karting around instead of shopping carting...

As far as saving money, not really. I do it for a few reasons. It keeps the drive interesting and somewhat entertaining and it also helps keep me concentrated on my surroundings so it's actually safer if you do it right...

No drafting semis and turning the ignition off while gliding in neutral or doing 50mph in the slow lane with your hazards on. I'm pretty sure those qualify as reckless driving at that point.

Will the 86/FR-S/BRZ have real-time fuel consumption info display on the dash? For example, as one of the selections that you can toggle through on the trip computer, if a trip computer is even available?

^ yea they showed MPG on the trip ODO screen on one of the gabillion videos

Me too, :thumbsup: I probably will be mostly doing the most basic "nut behind the wheel" mod more than anything. Aerotweaks, weight reductions, etc are all in my future.

I will be using E85 ASAP so my MPG will probably look average but I count fuel economy in cents per mile and energy per mile. I might break even without trying but it's hard to guess real world MPG without driving.

Hypermiling involves paying attention to your surroundings and conditions. It's much safer than just using cruise control or tailgating.

Given some practice, it can make a big difference. Just paying attention to your MPG with a gauge makes a big difference.

There is no certain car for hypermiling. The Prius is a popular icon for hypermiling because it does even better with hypermiling. But plenty of people hypermile trucks or other guzzlers because that is what they have to drive. It's vastly cheaper to improve your driving style than buy a newer car/truck. Hypermiling isn't just about reducing pollution or helping the environment it is also about saving money and/or wasting less Petroleum.

The driving you describe isn't driving spirited but driving like an idiot or a jerk. Hypermiling can be fun too, especially when you focus on maintaing momentum, using as little throttle as necessary, and not touching the brakes. Within reason, of course. It's not always about speed, it's more about smoothness.

Drafting/Tailgating is reckless and foolish. Pulse and glide depends on the driver, the savings are significant but it's often more work than most people are willing to do.

There is a technique for speed limit or slower driving called ridge riding, you ride the outside ridge to encourage people to pass instead of getting stuck behind you. That is not an option on a two lane roads but it works for highways and 4 lane roads. Being a courteous, attentative driver while hypermiling is a necessity.

You can easily guess how much this matters if you have heard any complaints about hypermilers.

Exceeding EPA rating while driving normally is pretty easy. EPA tests include quite a bit of braking, and they don't take a lot of things into consideration. Intelligent driving (anticipating stop light timing, reducing a bit of speed earlier to be able to roll through the light), and a careful foot (if you have auto transmission, you can usually tell when torque converter is locked by rpm changes without gear change) aka accelerating at 70% max torque, shifting to higher gear immediately or coaxing shifts on an auto with your foot etc. instead of just blindly pressing gas and brakes goes a long way.

I never really looked into what's involved in an E85 conversion but it sounds like something I'll be looking to do once the car is out...I'm getting off topic again :bonk: Off to do some research!

well said :thumbsup:

I would imagine this car should get mid 30's HWY MPG. If it doesn't, something's rather odd.

I got over 42mpg on a 300 mile trip once. That was in my 2008 Hyundai Elantra.

I can definitely see high 30's from the 86.

40 MPG!!! for reals:eyebulge:

very very good FC. For those who are from the other side of the planet, that equates to 17km/litre.

I only mentioned it because of MPG. I'm gonna do eet though.

I would take some salt and throw those numbers out the window. If the car got 40 miles per IMPERIAL gallon. That is 33 MPG (US) and 14km/L.

Fuel Efficiency Conversion Calculator

The 40 mpg in the UK converts to about 33 mpg in the US. Another thread already discussed this... but I do wish it got 40 mpg :thumbsup:.

I do agree with why you hypermiles, but there is a right and wrong application for it... I wouldn't say people go out of their way to hypermile to the point where the vehicle was bought purely for it, but if you went out there to buy a Vette, and you drive it around hypermiling, you can probably do better owning a prius is what I mean... (Though Vettes CAN get up to 50mpg)

I know someone who kinda made it his thing to spread the good word of hypermiling with his Tacoma on the forum I frequent... He did it purely out of saving money, and he did it with what he had... So you're spot on with that assumption because it's about saving money for him...

I still think in my mind, if you are going to buy "this" car, then I think you owe it to the car to drive it spiritedly :D At least that's how I figure it... Not looking for agreements here...

As for the driving I described, yeah that is an over animated way to say spirited driving...

Driving like a jerk is cutting someone off with a hair of space while you're doing 30mph difference compared to them while going 40 above limit... Or cutting across 4 lanes without pausing between, or purposely driving slow or "brake checking..."

I'm always anti street racing, so that's another can of worms, I don't condone it, but I do NOT follow the speed limit all the time, in fact I do live above it honestly 80% of the time... However, I don't think I'll consider myself a jerk for each second I'm above the limit :D Only being real :D

I'm gonna be hypermiling at 85 mph :lol:

Kauss, of course. I'm not buying this car to get super MPG. I chose this car because it is being focused on fun to drive and being involved with minimal electronics. I just want the MPG of a lesser powered econobox while I drive it. :lol:

If the Japan 10-15 is showing 29MPG and the European drive cycle is showing 29MPG/33MPG than this will only score less on the EPA 08+ cycle. Where they test it at speeds up to 80mph. :sigh:

I get 12.5 mpg in my truck, what were we talking about again?

The UK 40mpg claim is not only in larger imperial gallons but their estimates are wildly optimistic: I was looking at the VW UK site, and a Passat CC (family sedan) with a 1.8T is rated at 55MPG (that's 46 MPG US!) - as in not effing likely! They must do 'highway testing' at 50mph or something.
But seriously, if this car can get high 20s city & high 30s highway, I'll pay any price they ask. Other than that, I might look elsewhere.

Those pesky VW engines are quite good on the highway, their part load operation is stratified charge aka no pumping loss. Thermal efficiency is of course affected but not as much.

I like how you think KAuss.. :burnrubber:

I've only been here for a week, but I'm pretty sure I just found the dorkiest thread on the board.

I'm expecting it to be exactly the same as the 7th gen Celica GT-S. There are some very similar (or at least comparable) numbers with these two cars.

24 city / 32 highway

I think 30MPG might be combined number. My Corolla gets 32 average in city with at least 10 lights and 4 stop signs in 12 miles commute. (not very heavy traffic but it's there)
That car is rated 27/34 MPG by EPA. Has 1.8L, no DI and just 4 speed auto. Lights were anticipated and throttle is given gently.

My 2001 Miata gets 30 MPG (also measured at fill up) on 8 miles drive to work with about 4 lights and 6 stops. I'm a bit playful on throttle. It has older 1.8L engine with V-Tec stuff and 6 speed. That car was rated less than 30 on highway and even less in city by EPA.

Driving style will mean a lot on gas mileage, a light car like this will not lose so much energy on acceleration and braking. I expect higher gas mileage than Corolla on this car when driven in similar manner. Saving gas on commute means more money for fun.
