I think a Northstar under your hood would seal the deal.

 

music to my hears...............!!!!

 

140mph - across the top of New Mexico - highway 64 - I let the Carrera 4S go first (he had a radar detector)...


and there was more - but I won't push it higher than that on a highway - maybe a track...

 

You pone...........not sure what that means but my teenagers say it when somebody does something really cool.

 

Had some more fun with the Deville today.
I was curiousabout my fuel efficiency on the hwy. I heard numbers of 27-28 MPG on the hwy, but I haven't had an opportunity to take my Deville on a long road trip yet.

So today I thought I would perform a quick test.
On a long open stretch of hwycoming home from work,
I set the cruise control to 70 mph. Then I reset my MPG display.
To my surprise I was averaging over 31MPG at 70 mph! This remained solid on the display, no jumping around.
Then I increased my speed to about 75mph and it dropped down to about 27 MPG.
But still, this is excellent for a V8!
I know this is probably old news to some, but I'm really impressed!

Would love to hear reports from others on this.

I've seen 67 mpg on the highway for short stretches........on downhill grades! Generally average 24 mpg at cruising speed though but you can easily see 30+ in good conditions.

 

I usually try a top speed run on all of my cars... Out of curiosity I guess. Or maybe its the thrill of speed. Before my DTS, I had a Mercedes ML430 which was a money pit... Anyways, that truck hit 120 easy, and topped out at 130. My DTS is faster. It will run 110- 120 mph effortlessly and the speed governor kicks in at 130 mph. Its amazing that the car was still pulling at 130 mph. I really need to get that speed limiter raised!!!

Last month, I was coming home from my fiancee's house late one night, and had the cruise set on 75 mph. I saw a crotch rocket motorcycle fly past me going at least 100 mph. Well, I decided to test out all 32 valves under my hood so I stomped the gas pedal all the way to the floor. I caught him quick, at which point he looked over at me and gave me a "thumbs up". We slowed to about 80 mph, and he jumped behind me.

I was watching him in my rear view mirror, waiting for him to hit the gas. While watching him, I saw the front of his bike lift up a few inches, and I knew he had just hit the throttle! I buried my pedal in the carpet and I started inching AWAY from him very slowly. By about 115 mph, I had a good 1 1/2 car lengths on him. I looked at my digital dash and saw 123 mph! By this time, he started to catch up to me very slowly. Suddenly I felt a shudder and a jerk inside my Caddy... It was the damn speed limiter!!! At 130 mph he front tire was right next to my rear tire. He kept pulling past 130 mph, and I had to shut it down. I am ABSOLUTELY CONFIDENT that if I had the speed limiter removed, I would have shocked that biker boy. Imagine the look on his face when a two ton Cadillac ran his rocket bike to its limit!!! What a surprise indeed!!!

 

It's something addictive about the ride, but I don't push her too hard. I routinely hit 80 mph in my Deville. Which is not too much over the limit, since the speed limit is 70 mph where I live.

 

I've got a 2000 Deville and I get 25-26 MPG at speeds between 70-80 MPH on the interstate. Makes me happy.

 

Actually I take back what I posted above. On Sunday I went out of town to visit a friend and it was a 2 hour round trip on the interstate. I reset the MPG meter once I goton the interstae.WhenI got back from the trip I averaged 29.9 MPG going about 70-85MPH the whole time. Not bad at all, a V8 that gets 30MPG on the interstate.
