Yeah I was pretty surprised. (It’s actually 2.4 liters)this is a 2.5L 4 cyl engine at 5,500 lbs with passenger weight rolling up that pass at 75 mph, quiet and refined.
It’s a big vehicle. I’ve driven it with 7 people. Found myself doing 80 when going for 60. Personally, I could use more engine noise, but the public does not agree.
Variable valve timing, and direct injection have basically gotten rid of turbo lag. I think most of the annoying lag from a dead start in vehicles comes from the drive by wire system.
Direct injection, turbo, knock sensors, and of course a computer, have changed the situation with gasoline. You can actually now get more power when using high octane gas.
Turbo makes sense for high altitudes.
The negative of direct injection is carbon gunk build up on intake valves. No fuel coming in to clean them. There is no Ford approved method of cleaning afaik. Unless taking the heads off. (Chance of debris sucking into the turbo.) People do walnut shell blasting with a vacuum.
Suburu is planning on using most of that FA24 Ascent engine in the Wrx, and pushing it to 400hp with a different intake and other bits.
I will say that if you ever lose the turbo, the car going up hills will be like a 1970’s Land Rover. Been there on a Ford. So the 8 year warranty was smart.
My sister had an issue with their Ascent’s brake rotors. Replaced two times under warranty. Why the dealer doesn’t just cut them on the vehicle is beyond me.
My only critique is 20“ wheels are stupid, there isn’t enough rubber so it’s getting 18” wheels and the suspension should be more performance oriented, but that can be fixed if it bugs me enough
Hah, agree. I’ve been unable to make headway on that point so far. Maybe if they get stuck a few times I could convince them to get a set of snows or at least all weathers in 18”.
