The new LX platform cars (2005 Dodge Magnum and 2005 Chrysler 300 Series) have been tested by the EPA and they have released some intresting results on fuel mileage. Both cars are rear wheel drive and feature the 2.7L V-6, 3.5L V-6, and 5.7L HEMI V-8 w/ Multiple Displacement System (MDS). The 2.7L V-6 24-valve engine features multi-point fuel injection and produces 190 horsepower at 5,800 RPM and 190 pounds-feet of torque at 4,850 RPM. The 3.5L high-output single overhead cam 24-valve V-6 engine generates 250 horsepower at 6,400 rpm with 250 pounds-feet of torque at 3,900 RPM. The 5.7L HEMI V-8 will make 340 horsepower (Magnum) 345 horsepower (300C) and 390 ft-lbs of torque.

MPG City/Hwy:
2.7L V-6: 18/25
3.5L V-6: 18/24
5.7L HEMI V-8: 17/23

Not bad considering how big the car is!

That is good mileage, why 3.5 V-6 instead of 3.7 V-6?

 

The 3.7L "MAGNUM" V-6 is for the truck models... iron block and heads... the 3.5L HO V-6 has aluminum heads and block.... plus the 3.5L is a lot more powerful than the 3.7L... 3.7L has 210/215 horsepower depending on the model... and the 3.5L HO V-6 has 250/255 horsepower depending on the model! Plus the 3.5L is more fuel efficent!

I have a feeling I'm going to sound stupid for saying this but if the bigger 3.7 V-6 is less powerful than the smaller 3.5 V-6, what is it doing in a truck, and also why not drop the 3.7 and just use the 3.5? Wouldn't that be cheaper? Why not also up the 4.7 V-8's horsepower to 290-300ish so it would be more powerful than the V-6 (the 3.5 is just as powerful as the 4.7) and could compete with Chevy's 5.3 V-8?

 

I second all of vHiEpMeIr's questions!! LOL!!

What they are doing seems like it would cost money, it's like BMW's engine line next year, their High-Performance V-6 is going to be more powerful than their High-Performance V-8, that makes no sense.
