I know those numbers are from Nissan, but there have been numerous reports from members who have found that this weight gain does not hold true. These reports are from back to back weight measurements on the same scale, and there is no 200lb weight gain to be found.

One thing to keep in mind is that Solo has a Nismo version which of course has a number of aero parts that increase its weight over a regular HR.

 

Exactly.

Even more so than reporting horsepower numbers, manufacturers have a legal obligation to accurately report the weights of their vehicles to DOT. There's no reason to under or over-report vehicle weights. The whole "conspiracy" theory is a little bit too much.

People change tires, windshields, spare tires, carpet mats, whatever... fluid levels vary, aftermarket parts, wheels, tires and other items all matter. There ARE slight manufacturer differences from car to car... but not much. The best predictor is manufacturer weight specs.

Plus, look at the reviews by mags such as C&D... for all their shortcomings, C&D at least weighs the car during testing on a certified scale, and puts it on their data sheet. These numbers have historically supported the offical published numbers, and I would trust them more than a personally owned car with who know now many variations on scales at a race track or anywhere else with questionable calibrations.

Or another way to look at it, is over the years, with additional features, safety measures, larger wheels/tires, improved materials, heavier engines, etc... how would it NOT gain weight?

 

 

Lets see the new 370Z has a full aluminum side doors, hood and rear hatch...this is much better than the 350Z in itself. This is what the GTR has. The 370Z is much closer is design to the GTR that people think.

Also the syncro rev matching system in the 6 speed manual sport package models might make the car shift faster....so the 370Z which has more HP and less weight than the 350Z and a better transmission (even the auto is a 7 speed, heck they got the G37 sedan 7 speed auto doing 5.4 secs to 60 MPH) will be a faster car.

I wonder what they will do with the convertible version? Will it be soft top or powered hardtop?

How much does the G37 convertible weigh? How much does a G37 coupe weigh?

Does not a 3.7 liter engine in the G37 dyno over 280 HP to the rear wheels? Show me a stock 350Z engine dynoing over 280 HP to the wheels?

The styling and interior of the 370Z blows the 350Z out of the water.

But you can get used 350Zs cheap these days...its still a good car..and it will get cheaper to own once the 370Zs come out in January.

 

Isn't the rev-matching just for downshifts?

 

The last sentence of literature distributed at the LA Auto Show says:

"The system also works when upshifting to give you a smooth flow of power when accelerating, and can also be turned off by a switch mounted next to the driver"

Perhaps during upshifts the system does not allow the throttle to close completely so the revs drop less?

There was also a transmission at the show which showed the shift lever position sensor on the top of the transmission. The system is more complex than one would think at first blush.
