Jay Sixspeedrt Posted February 5, 2012 Report Share Posted February 5, 2012 I have a GPS speedometer app for my DroidX, and the app has got a 0-60 mph timer built into it. So I took my 2012 Hero AWD 3.6 onto a backroad, and ran a 0-60 mph timing in Autostick mode I only did one run - 7.4 seconds. I think that's really impressive for a 4000 lb+ vehicle with a full tank of gas, and contents in the trunk area, and one that will get 22 mpg on average. I shifted into 2nd at about 6000 rpm - maybe I could shave a couple tenths off that time by shifting closer to redline, and also 'loading' the transmission by reving up to 2000 rpm before releasing brake? At any rate, fun stuff. Quote Link to comment Share on other sites More sharing options...
redtomatoman Posted February 5, 2012 Report Share Posted February 5, 2012 I'd say pushing 5000 lbs for the AWD. It would be interesting to compare manual mode to the "D" or automatic mode. 7.4 is pretty good. Interesting that you did not shift from 1st until 6000. I suppose I'd be afraid I'd do some damage. I know that computer would override any bad decisions and shift before damage is done, but it seems that the computer would have intervened before 6000 rpm. What app exactly is that? Fun stuff, I agree. Peace. Quote Link to comment Share on other sites More sharing options...
Jay Sixspeedrt Posted February 5, 2012 Author Report Share Posted February 5, 2012 Redline for the Pentastar is 6400 rpm http://en.wikipedia.org/wiki/Chrysler_Pentastar_engine The engine is electronically protected to prevent over-revving - you hit the redline and the engine rpms hold at the limit. In general, these sorts of engines make more power higher in their RPM range so shifting higher in the rpm range is desirable. Haven't played much yet, but the Pentastar may deliver best acceleration by shifting just shy of the 6400 rpm redline (6300-6350 rpm) As for the app, it's called GPS Speed Free. Look around though, there may be better apps with more functions in the Marketplace. Can't take screen shots, for example, with GPS Speed Free.

Jay Sixspeedrt Posted February 19, 2012 Author Report Share Posted February 19, 2012 Hey, the Hero did a 7.0 second 0-60 mph today - preloaded the tranny by bringing RPM to 1800 with my foot on the brake, floored and released brake at same time. Think with practice i can get her the high 6.0s. That's great for a vehicle like this. The Pentastar and 6 speed tranny really accelerate!

Jod Posted February 19, 2012 Report Share Posted February 19, 2012 I'm curious to how your time would compare with letting the tranny in "D" and just letting it do its own thing. I am quite impressed by how the transmission keeps the revs up when you are hard on the gas from a stop. It seems to be programmed to keep the revs up under hard acceleration. How about one more run for the records; this time in D. ?? Quote Link to comment Share on other sites More sharing options...
Jay Sixspeedrt Posted February 19, 2012 Author Report Share Posted February 19, 2012 I did full auto mode that time too, I didn't manually shift. Most guys that drag race Dodge cars with automatic trannys just let the tranny do it's thing. Quote Link to comment Share on other sites More sharing options...
Jod Posted February 19, 2012 Report Share Posted February 19, 2012 Fantastic! I would like to drive the Chry 200 with this motor in it. I can't believe the take off in my FWD Journey; I would imagine its even more so in the 200 or Avenger. It will be interesting to see if they do indeed throw a turbo or two on this engine.

Jay Sixspeedrt Posted February 20, 2012 Author Report Share Posted February 20, 2012 The Pentastar with a turbo would be off the charts Quote Link to comment Share on other sites More sharing options...

magnumrtawd Posted September 8, 2012 Report Share Posted September 8, 2012 Hello from Toledo Oh. I currently own a 05 Magnum RT AWD. 0 to 60 times 5.6 to 5.8. I test drove a new Avenger rt a while back and was very impressed with its zero to 60 acceleration. In fact it felt quicker then my Magnum. Torque steer is bad... You better have a good grip on the wheel when you floor it. Also, Turn off the traction control and power brake it.. It will smoke the tires!!! This little car could be the Roadrunner of future. And the price is right. Quote Link to comment Share on other sites More sharing options...
