Just in case you hadn't noticed, the automatic trans on the V6 Mazda 6 is also a 5 speed.
On a related note, some automakers are going to even more gears on the automatic transmissions. Mercedes is about to intorduce a 7 speed.
I guess that the horsepower race that the industry is moving stronger into is going to include a transmission race as well with a four speed automatic becoming old school real fast.
As well as the five speed automatic runs in the Lincoln LS I can't help but wonder just how well a Mazda 6 with a five speed automatic would run.
