Just wondering which one is faster? I have a 05 sts v8 and I think its really quick for the sedan, however I recently drove a 09 CTS v6 with the direct inject system and it really surprised me. I would love to see a video of a sts vs a new cts but cant find it. Just wondering if anyone knew which one was quicker, and/or faster.

Thanks

I test drove a 2009 CTS with the D/I, and my car (a 2007 STS with the V8) did seem quicker, and did sound much better WOT. I wish I had some numbers, or a video to post, but alas, I do not.

Direct injection V6 any day--that's why the N* is cancelled

I am sure that the DI V6 CTS is quicker based on pretty comparable HP and less car to move. Plus, WAY better MPG. But then you don't get to drive a N*!

Driving a N* is nice, but if you have withdrawal, you can always rent a DTS or Lucerne once in a while

What kind of mpg does the DI v6 get?

 

[jamesbalzer]

29 mpg

What kind of mpg does the DI v6 get?

With my 08 AWD I have recorded over the last two weeks 22.4mpg, average speed 53.3 mph; that includes a run I did to Cleveland where I averaged 81.7mph, other than that it's a 50/50 blend of city expressway and city streets.

The DI 6 rocks in my book, as the car feels more nimble than a N* model, and the mpg is stellar in my opinion.

From http://www.cadillac.com/comparator/...t=cadillac&compModel=sts&cmpModelTrimID=24296

I calculate Weight/TQ
STS= 12.68lb per lb/ft @4400RPM
CTS= 14.18lb per lb/ft @5200RPM

Weight/HP
STS=12.48lb/HP
CTS=12.74lb/HP

Both have 6 speed autos, both have 3.42 final... Would imply the STS V8 should be quicker.

Also, stated fuel economy is only 2mpg different. 15/24 vs 17/26

Daily commuting I'm getting 21-22 in my N*
Highway I'm getting 25

There is nothing like the sound and Torque of the N*. A DTS or Lucrene can hardly compare to a 1SG STS for performance. Too bad they did not DI the N*

So true. It's reputed to be an expensive engine but it is completely figured-out. What's that worth?

I felt the same way about my '93 350 small block (5.7l). Technically, the next year's LT1 was a better motor but mine was way more reliable and pulled strong.
