In school today, covering the changes in the 2010 Subaru Legacy.
Thought I would sum up what was covered. This is a World Wide Launch.
The car is bigger all around
The NA engine series will be 170 hp with a splitcase 6 speed manual or
a “lineartronic” CVT transmission. One instructor drove his cvt on a
trip; averaged 30 mpg without trying. Not bad numbers
The Turbo will have a 265 HP manual only transmission with a beefed up
1st 2nd and reverse gears.
Electronic park brake. No handle or foot lever. A button. This system
requires resetting the system after replacing the brake shoes or doing
any maintenance on them. There is also a clutch stroke sensor-
measures the clutch movement- it also has to be calibrated if any
clutch work is done.
All cars have a hillholder, even the automatics????
A clutchless ac compressor- one serp belt. This design eliminates the
a/c clutch surging the engine up and down. If the compressor freezes
up it will shear a part and continue to freewheel so you don’t worry
about the belt
The car has a sub frame for the engine. If the steering rack was to be
removed, you have to support the engine from the top and remove it.
There is a front center motor mount and two rear transmission mounts.
New Turbo!
Located ft lower of engine. Eliminates the distance between the energy
source and the turbo so less turbo lag. Looks easier to get to,
overall. Bolts directly to the cat, so the cat gets up to temperature
quicker and eliminates the need for the secondary air system.
The turbo is at the lowest point of the lubrication system, so there
is a scavenge oil pump system. The pump itself is mounted to the back
of the cyl head and driven off a intake cam.
The car has an oil level sensor- will set a light if the oil gets too
low. The light doesn’t set a dtc, but it has to be reset at the
dealer. We are still investigating that it may reset on its own too. I
think Subaru is getting tired of buying engines for people who don’t
change the oil or let it get low… we will see what happens here.
Anyway, this is a summery of the big changes, Tomorrow we take apart a
cvt transmission
