you thought toyota was fuel efficient?

new 3.7L stang 6 spd automatic puts out 31 mpg hwy.

must be some gear tricks huh?


of course, that's not the whole picture.

waiting to see acceleration numbers

joe80

i would probably never drive a mustang, but that's an amazing number. accord 4banger gets 31 highway. wow.

The 19/31 Mustang is about 350 pounds lighter than the 19/26 GS350, so overall it sounds like Ford has finally caught up to where Lexus was 5 years ago (if only Lexus/Toyota did put the V6 in a ~3350-pound car).

LexBob2

It's about time. The old 4.0L 190hp V6 was a dinosaur that hung around too long.

Any 6 cylinders on the market today rated for more than 31 Hwy? Only the 335d I guess.

Is this engine direct injected?

I'm willing to speculate that there's a super tall 6th gear here. It's an impressive number considering the so-so aerodynamics of the 'Stang.

IS-SV

Yep, that's a groaning rental car we won't miss.

LexFather

Its with the auto only I think. Still I am glad this thread was started b/c I think it shows how silly some I-4s are in regards to economy and how many small cars just are not as efficient as they need to be.

Big Kudos to Ford here with this new engine. Yet it STILL has 300hp.

Now that is "Advance"

definitely good for ford, i am glad they are all looking info fuel efficiency

is that official epa numbers or number achieved by some people? i have seen is350 and gs350 doing over 30mpg as well on highways. even the isf, i have seen people doing 27+

Mister Two

I'd bet so; otherwise its city mileage should've been better than the much heavier GS350. Also EPA mileage is obtained through running the car on a dyno, so aerodynamics play no part in those EPA numbers, which means the discrepancy between the Mustang's EPA highway mileage and its real-world highway mileage is likely gonna be quite a bit worse than that of the slicker GS.

IS-SV

Note: regarding aerodynamics which do come into play in EPA mileage testing.

The drive wheels are placed on a dynamometer that simulates the driving environment.

The energy required to move the rollers is adjusted to account for wind resistance and the vehicle's weight.

Mister Two

Ah, thanks for the correction. Never knew about the aero factor in the dyno adjustment.

Nice. It seems as though everyone else will soon be playing catchup to Ford and GM. Ford's Fiesta and Focus will set new standards this coming year with highway ratings of 40 mpg with their high 6 speed transmissions (a class first).

We can no longer assume Toyota and Honda the efficiency benchmarks. Toyota and Honda needs to follow suit with 6 speeds to compete for highway numbers.

Of course, I wouldn't call this that amazing. After all, the 6.2L 430hp V8 Corvette gets 26mpg highway. That's what a high 6th gear and bullet-like aerodynamics will do.

TRDFantasy

Aerodynamics, combined with a tall 6th-gear in the auto is what allows it to get such a number, but a good achievement from Ford .

The tall 6th-gear is pretty much confirmed.

If you notice, the manual Stang with the same engine gets quite a bit less in terms of fuel economy.

SLegacy99

1 MPG....wouldnt call that quite a bit less.

Chances are you will get better with the MT if you care to. Do some short shifts, which obviously isn't ideal for quick acceleration, but is more valuable to saving fuel than any automatic I've driven. No that's not fair. Any non hybrid auto that I have driven.
