The "HPS" system across the board on Maxx model for 2007 is an engine driven pump. There is such a thing as an EHPS (electro-hydraulic...)system but this is not it.
 
I believe new engine in 2007 was enough to tip the scales on the heavier Maxx to require the HPS system. Not sure exactly why though....weight or HP increase or a combination.
 
Anyways as order guide states the sedan body style still has "EPS" on everything but the "SS" model.

Please say it isn't so. I have no problem with electric steering.
 
Same here. I've grown to like the electric steering. It makes parking such a breeze. I can put up with the overly light feel on the road in exchange for the maneuverability in tight spaces.

ok, thank you E2. Good info!
   
Still, Hydraulic's a step backwards; several other cars with higher HP have electric systems that work fine. A pity Chevrolet could not do the same.

Maybe the electric motor would draw too much power because of the heavier engine. The Malibu EPS draws in the region of 65amps. Correct me if I am wrong. Anyway, it is fused with a 100amp fuse.

65 amps? That is alot of current for an electric motor!
I liked the EPS the 1st time I tried it. I think it's very progressive and a great idea. I cant understand those who complain about it. I do hope it proves to be reliable long term.

Glad to see GM has not given up on the EPS for the Malibu, with 18K I have not had a problem with mine. I just hope if I have problems after warranty they won't just say too bad, should have paid big bucks for extended warranty. I like the EPS and don't regret buying it .

That is about what the motor draws when the car is stationary and you turn the wheels. On the highway where a minimum of effort is required the motor would draw less energy as opposed to a hydraulic pump which draws maximum energy from the engine even though the wheels are not turned. Hence the fuel saving with the EPS. The EPS motor is a long life brushless DC motor so hopefully it should last the lifetime of the car.
 
I should imagine that a car with a heavier engine than the Malibu would draw even more amps when stationary and this could be a limiting factor with heavier cars.

I'm sure the power steering fuse in my car says 100amp. I'll check in the morning. But as you say, who is counting - 80 amps is still a lot. Do tell what a Megafuse is. Some kind of a slo-blow thing?

Take another look - I am pretty sure you will see it is 80 Amp. Don't look at owner manual - they don't show fuse sizes
 
You are correct, megafuse is a slo-blow, bolt-down type of fuse. Actually 80A is pretty small for the Megafuse style which go up to 250 Amp size. I think smallest is 40 Amps.
 
If you want to learn more I suggest you could visit www.littelfuse.com.
