I just got back from my first trip of any length with my Sonata and was
disappointed in the mileage. I got 30.8 on the outbound leg (200 miles)
which is basically what I've been getting commuting to work. This was
on good two-lane roads (routes 6 and 66 in Western PA), however, we did
get caught in a couple of construction zones and spent a fair number of
miles driving around Grove City so that may have offset the highway
mileage. The car seemed to do real well on the way back, but I haven't
filled it up to check yet. I made the trip back (190 miles) and the
gauge was right on the 3/4 tank mark. I typically get 140-150 before it
hits this point so I think the mileage on the highway was pretty good.
However, I'll drive it to work this week before filling it again so that
will bring the average down a little. Still need a good long highway
trip to get a good test.
Bear in mind that those numbers were for the LX model as I recall. The GLS
V6 is significantly lighter than the LX, but a bit heavier than the GL-4.
With my traction control off, I have done a few 6.5 sec. 0-60 unofficial
runs. While I agree that it would be close to 30 MPH, I would be ahead and
pulling away. With that said, the 4 has my respect compared to other 4's
of the same class.
That wasn't my recollection, but unfortunately the web site now has the
07 models. The big difference was the V-6 vs. the 4, not the trip
levels. Even the automatic trans doesn't add that much weight, it was
the engine and the heavier suspension required to support it that
appears to be the big difference. Even for the 07 models the Limited
(which appears to be the successor to the LX) and the SE (appears to be
similar to the former GXL-V6) have identical weights. The GLS
(successor to the GL) weighs more than 200 lbs less than the SE and
Limited with the standard transmission and just under 200 lbs less with
the automatic. 200 lbs makes a difference on a car that weighs less
than 3500 lbs.
The standard shift tranny also has a slightly lower final drive ratio
than the 5 speed automatic (althought it is higher than the 4 speed auto
if the web site is correct - but this doesn't seem right so I'm
wondering if they made a typo). However, not knowing the 1st gear
ratios I don't know if the overall ratio is less or more for the 4
cylinder. I'm guessing it is a fair bit lower given the relatively
minor performance difference from the 50% more torque in the V-6. I
suspect that much of that torque advantage is lost in the gearing.
The 07's don't really compare. My GLS only has 16" wheels. I would
imagine that is probably 50 lbs. right there, but admittedly, that is a
guess. I can only guess at the rest too, since none of the car
magazines that I read tested a GLS V6 (all LX's), but you've got a few
other things that could easily add up to 50 lbs. or more.
The final drive ratio is so small of a difference it is insignificant,
but like you said, the 5 gear ratios could be different. Although both
being 5 speeds I would suspect they are similar too.
If you have ever been into reading the car magazines like I have for the
last 25 years, you would know that the numbers even they come up with
are variable and not always accurate. Car and Driver seems to have the
most consistant numbers and it put the LX at 6.6 seconds to 60 MPH. I'd
be willing to bet that the GL I4 would be in the low 8's for a 0-60 run.
That is a very significant difference. You don't just add 50% more
torque and HP and reduce your times by 50%, even if you could keep the
weight the same. It is far from a linear relationship.
I'm 95% sure that the 06 figures were similar with the V-6 models coming
in ~200 lbs heavier than the I-4. Unfortunately, I don't see an archive
with the 06 data at the Hyundai web site.
Usually standard transmission cars are geared much lower than the
automatics so I suspect that the 3.77 really should be for the 5 speed
manual and the 3.44 for the 4-speed automatic. Then the 3.33 for the 5
speed automatic would be consistent as it could handle a higher final
drive ratio as it likely has a lower 1st gear given the extra gearset.
I was using the numbers Hyundai published. I don't see why they would
have any reason to intentionally skew the V-6 vs. the 4 cylinder. I
suspect their profit margin is larger on the V-6 so if anything the
would want to make the V-6 look better against the 4 rather than worse.
Since F=ma, if the torque is 50% greater then the acceleration will be
50% greater also since this is a linear relationship.
However, since x(t) = 1/2*a*t^2, t=sqrt((2*x(t)/a)), the difference in
time will vary as to the square root of the change in acceleration. So
a 50% increase in acceleration will yield only a 22% reduction in time
over a given distance (say 1/4 mile). However, this assumes all else is
equal, which it isn't as the V-6 is a couple of hundred pounds heavier
and has different gear ratios. I believe the performance posted by
Hyundai had the performance difference being only in the 10% range. I
posted the stats a while back, but don't remember them precisely from
Actually, isn't the aluminum block 2.7L *lighter* than the cast iron
Is the 3.3L a cast iron block?
BTW - HP is a silly figure, the greater torque curve dictates the
drivability of a car, the peak torque/HP means much less than most
people want to put into it..
I do miss my Explorer's ungodly low-end torque... I don't miss the pansy
french-built transmissions said torque destroyed...
I dunno... Can you have 3 cylinders shut down and it keep running?
On the 2.7 you can ;)
Of course that only happens on the occasion a cam jumps time (ouch), or
somebody forgets to plug the 'rear bank' of fuel injectors back in ;)
I dunno, my 2.7 has
screwed to it right now.
Damned nice filter. I think you could smack it with a roofing hammer
and not dent it.
well...one more time...I got 06 Sonata V-6 filters from Haddah Hyundai in
Springfield Mass for $6.75 with free shipping...the freeshipping was only
for the month of March. I also ordered cabin air filters and engine air
filters for Cheap!!! This is the third time I have posted this
message...so if you guys want to pay 20 bucks...go ahead!!
Can't speak for anyone else but I looked at Haddah when you first
mentioned it. OK, no online ordering and no price lists. Might be a
fine dealer but having to order by email or a phonecall is kind of last
