just got my touring model on the corner weights this morning.

full details here:

weight

bottom line: with the gas needle at two ticks over half, it weighs 2969lbs. but more importantly, the front half weighs 1563, the back half weighs 1407, only 160 lbs less! next saturday (first autocross) seems so far away...

 

Thanks for the info....

Does the weight include the baby in the back?

 

is that with you inside? if not, the driver would add even more weight to the front

 

Cross weights are within 20 lbs of one another (with driver) - very nice.

 

I posted the weights both with me in the car and without me in the car. I left my son & his car seat at home.

 

Thanks for sharing that.
So, does cross weights mean, that with the driver in the car, the weight is distributed somewhat to the other corners of the car?

 

That's wrong. A magazine hear in Greece did the same thing with the 8 with 3/4 of gas. The distribusion was 51.9% front and 48.1 rear when empty (1380kg). Then up to four people they measured:
51.75%-48.25% front-rear with driver
51.68%-48.32% front-rear with driver and passanger
49%-51% front-rear with four passangers

If you want I can post more detailed figures of the measurement. I think in the front seats the weight is equally distributed, slightly more to the rear...

 

Excellent info. I would like to find some corner scales here in the bay area and see what my base model weighs.

 

Interesting info, may I ask a silly question? Where's the battery located in these models? ( I don't yet own an eight, sorry.)

If it's in the same place as my 7's (LF corner) then it would seem a battery relocation to the RR would be very beneficial.

The battery is located in the front left middle next to the intake so it is not detrimental to corner weights that much. It does add weight in the front but there is so little there anyway as everything else is mostly behind the front wheels.

 

Cross weights are an important measure. Ideally, the sum of the LF and the RR would equal the sum of the RF and the LR. As the car's cross weights start to diverge, it's handling balance (understeer vs. oversteer) will start to diverge, based on corner direction. For example, if the corner weights do not match, the car will understeer more strongly in right hand turns vs. left hand turns (or vice versa).

To put this in perspective, one of the objectives of corner-weighting a car with height adjustable coilovers is to make the cross weights equal. It looks like Mazda has done a great job on this right out of the box, re-iterating how well this car is setup from the factory. Pretty impressive - I wonder how many other cars have such well matched cross weights right from the factory? I suspect not many.
