Which is faster, the 2010 Forester XT or the 2010 Outback 3.6R?

Both of these vehicles are the fastest in their respective model ranges, but which is faster - the 2010 Subaru Forester XT with the turbocharged four cylinder engine or the Subaru Outback 3.6R with its Boxer six cylinder?

The Forester is a bit lighter and probably a bit quicker, too. There haven't been many track tests of the 3.6R yet, Edmunds only did a quick First Drive and didn't measure acceleration numbers.

I think the turbo four is faster in cars of the same weight.

Road Trend just tested the 2010 Legacy GT turbo 2.5 4-cylinder, in an article subtitled "The Only Mainstream Midsize Sedan That Can Call Itself a "Sport Sedan". This title would seem to exclude the naturally aspirated 3.6 6-cylinder Legacy.

09 Forester XT
0-60 : 6.6 sec, 1/4 mi : 15.1 sec

10 Outback 3.6R
0-60 : 7.1 sec, 1/4 mi : 15.5 sec

These just figure, less than 1 sec difference and don't feel it as who step on the gas first, clean air & oil filter, clean oil, etc can make a difference also.

"... clean... oil filter, clean oil, etc can make a difference..."

So an engine makes more power after an oil change? Why is that?

Please, please, tell me more about how new clean oil does the run faster thing???

ateixeira

The old oil would have to be pretty darn dirty (sludged even?) to cause loss in power.

Newer, thinner oils help engines run more efficiently, but even then it's a stretch to say they gain power measurably.
