Pre-production 370Zs weighed a little less, but then additional safety equipment was added to the final product which added weight.

Anyways, all 07-08 350Zs (also 09 Convertibles) had the new VQ35HR motor, which is essentially the motor our VQ37HR is based on - just with less displacement and a few minor internal differences. Power differences between 350Zs were: 287HP > 300HP > 306HP. So our 370Z has anywhere between 26-45HP more. 370Zs also have a carbon fiber driveshaft, which reduces unsprung weight considerably for much better acceleration.

Then you simply look at the interiors - the 350Zs best interior with navi still looks like it was made from a bin of plastics used to make legos. Where as the 370Zs best interior looks and feels absolutely wonderful all around. Headlights, taillights, every single body panel, suspension, etc. are all different - the cars share practically nothing expect for the 6-speed transmission.

The end.

Seriously, as an owner of both and a fan of the car, the 370 chassis is still the FM platform like the 350Z was. As was mentioned, the chassis is shorter, wider, lighter, stiffer... The 370Z is improved in almost every way.

I honestly didn't believe it would be that great. I got in my 350Z (not worn out or anything, just 15K miles!) and drove it to the dealer to test out a 370 thinking it would feel about the same but just look better.

It's not a night-and-day difference, but the turn-in is sharper, the car feels much more precise, the whole experience is just better in terms of a "sports car feel."

Anyway, due to it being the same shared platform I don't know if I'd say it's a whole different car but it's certainly different enough where it counts.
