Do you think that the Santa Fe Base model should replace the 2.7 liter V6 Mu engine with the Updated 2.4 liter Theta Engine, the new Theta engine should produce about 180 plus horsepower in the Santa Fe.


What do you think ?

Should a Diesel or Hybrid should be offered in all trim levels?

byronguidry3732 is an unknown quantity at this point
Dear cant,

Congress is forcing our hand. Within 5 years, I predict that you will have a US market diesel engine for the Santa Fe, a hybrid model, and probably the Theta engine for the Santa Fe.

The 2.7 liter is dependable, but low output for its fuel economy. the Audi 2.8 liter V6 FSI produces 210 hp output without turbo. the Nissan VQ25HR 2.5 liter V6 produces 225 hp without turbo. Even the Mu version of the Hyundai 2.7 liter only produces 185 hp.

Why not use a smaller engine to produce 180 hp but get better gas mileage?

Where's my bailout?

I think it makes sense because the 2.7 liter takes as much gas a 3.3 liter, the 2.4 should be standard, the mu has to go.

I wonder how the 2.7L would fair with the 3.3L engine's 5 speed auto and gearing?

I wonder how the 3.3L would fair with a 6 speed DSG auto or 6 speed stick?

The Mu is much cheaper than the 3.3 by about 1000-2000 depending on which vehicle it is used in, the mu is just a updated version of the delta, it still uses a timing belt which is a disadvantage over a timing in the long run, i would rather have the 2.4 liter Theta II updated with 190hp with the current dual exhuast setup over mu, in my opinion the 35mpg standards are around the corner, plus the 4 cylinder uses a timing chain and only has four spark plugs which are very easy to replace.

the 6 cyl has less internal friction. i had an elantra that got less milage than my 05 2.7 v-6 sonata due to weak output- you have to step into it much more often.

i also had the 06 sonata with a 3.3l , and after about 12, 000 miles, the mileage nosedived. the aluminum block screeched on startup in cold weather, also.

i got the 07 santa fe with the 2.7, and now both my 05 sonata and 07 santa fe have the 2.7 l v-6. they could add a 5-speed auto and direct gasoline injection to this engine. the 4 cylinder you describe is also used by mitsu and chrysler, and gets lousy acceleration and economy results in real-world driving.

hyundai could better results by using more light-weight materials to reduce the overall curb weight and adding better intake and tranny improvements.

In my opinion the 2.4 should be the base engine because of lower cost of operation, and maintenance the updated engine has almost 185 hp, that is why the 2.7 mu has to go.

Thumbs up



if a 2.0L engine in an elantra had a higher cost of operation than the 2.7 L in the santa fe, what makes you think that a 2.4 L engine in a santa fe would cost less!???

based on personal experience, i can say that it would not.

unless you drive like a granny on subdays only.

The 2.0 gets good gas milage, even small cars only get 16 pg in the city on the highway the kia spectra in my family gets over 35mpg, my 06 sonata gets about 25-30mpg on the highway.
