Just wondering if anyone has ever weighed their IS? I weighted mine today at a truck stop and it came in at 3860 with me in it and almost full of fuel.

 

Not a 350 but I weighed by 450h at the drag strip and it was 4120 or so...right on target with what Lexus states. I was not in the car.

 

Never compared the weights of the 250 to 350, but damn...only 75 lbs more for 100 ponies! Nice work Lexus!!!

So...full tank being 110 lbs, OP should be around ~225 lbs? Are we close?

 

i always like to do this with my cars and am interested what other 350's weight in daily form (fuel and driver). hopefully there's a scale at the track...and it's working.

 

Yup, every time I allow passengers

 

Pretty good math, give or take a few lbs.
