Registration weight is 3019, and I have found that here in virginia that the registration weight is within 1 to 2 hundred pounds of actual wet weight.

 

Mine is registered at 3202#. It probably depends on model and options.

 

CH - I think yours has more "Heavy Metal."

 

for every 100 lbs it will run one tenth of a second slower, so an extra 1000 lbs compared to a vehicle thats otherwise exactly the same and driven exactly the same it will run 1 second slower.

 

Times as posted in the February 2006 Car & Driver. The test HHR had a 2.4 and 5-speed manual.

0-60 mph : 8.0 seconds
0-90 mph : 17.4 seconds
1/4 mile : 16.1 seconds @ 87 mph
Rolling 5-60 mph: 8.9 seconds
The top speed is 126

 

numbers seem botched. 0-60 at 8.0 yet 5-60 is 8.9? something doesn't add up...

 

I thought all cars took longer to get to 60 from a rolling start.

 

They usually do, because from a dead stop everything hooks up much quicker, and from a rolling start an automatic has to go through the gyrations of kick down and that takes time. With a manual, rolling at 5 MPH usually means your in second gear and at that speed second gear will want to bog the engine. You can do it in first gear but be prepared to shift into second very quickly after you launch because your already rolling and engine RPM is already building.

 

After sorting through all the expert / amateur opinions in this thread, I've scientifically concluded why SoCal's HHR is soooo fast....


It's the stubby antenna, folks!! Gotta be worth a full second or more on the 1/4 mi. and at least 15 MPH trap speed!! :)

So... I ordered one of the previously guarded speed-secret antennas!!

Look out world!!!

 

My HHR LT1
From the factory with the 2.2 ecotech and the 5 speed tranny ran

16.868 in the 1/4 mile at a speed of 81.54
