Weight was 1,393kg with around 85 liters of fuel. This is a non-PCCB car with very few options.

GlennMc

are the official Porsche figures for a wet or dry car ??

how much would that fuel weigh ??

Cheers

That's 3071 lbs. for the other metrically challenged.

3064.6 lbs, How much does 85 liters of fuel weigh?

jimculp

A liter of water weighs 2.2 lbs.
So that's 187 lbs.
Dry weight- 2884 lbs.

JFT

Porsche's weights are for wet cars Glenn, but they do seem to exaggerate in the wrong direction on weight. Actually it was better than I thought.

Fuel is lighter than water, but not sure by how much. Around 80%?

RR

Porsches figures are 1375kg Unladen weight for the RS.

from DMV California website

The "unladen weight" of a vehicle is the weight equipped and ready for operation on the road including the body, fenders, oil in motor, radiator full of water, with five gallons of gasoline or equivalent weight of other motor fuel

Five gallons is 19 litres. And I think Porsche's weight of 1375kg is for a PCCB car and JFT's has steel breaks. So finally we all know that Porsche's figures ARE accurate.

Hmm. I waspretty sure Porsche's quoted weight was with standard equipemnt, i.e. without PCCB.

This is fascinating -- if this is true, why is the regular GT3 (at least in the US) so much heavier? Could the mandatory sunroof really weight that much?

RR

One gallon of gas weighs 6.25lbs. One litre of gasoline weighs 1.64lbs.
85L-19L=66L 66x1.64=108.24

So JTF's car with 19L of fuel weighs (Unladen weight) 2962.76lbs or 1346kg, which is lighter than what Porsche's prints as the GT3RS's Unladen weight.

JFT

Good question. The buckets should be cancelled out by the cage, so the difference should be sunroof + the other 20kg saving between the RS and the GT3. I really was expecting it to weigh more based on other weights quoted here. It was weighed by the Swedish Motor Vehicle Inspection Company, which is run by the government. I assume it's no more and no less accurate than private companies equipment. I was not able to get weight on each wheel, which I would have like.

RR

Ok JTF you must be right about the standard equipment.

Yeah it has to be the sunroof.
But I also remember someone else saying that the US cars have an extra aluminum bumber behind the rear bumber, and perhaps on the front bumber as well.

Anyone know what a standard 997 Carrera ways for a comparision to a GT3?

JFT,

Can you please confirm you have an Euro version 997 GT3 RS?

Based on the fuel weight for Sunoco 93, your car hit the scale at:

2,925 lbs with no fuel.
3,065 lbs with almost a full ROW tank (22.5 gallons out of 23.77 gallons). The US versions come with the smaller 17.7 gallons fuel tank.

Do you have the Rollbar or Full Cage?
Carbon Seats?
Plexi Rear Window?

Thanks

p.s. I'm shocked! The US GT3 RS could be under 2,950 lbs with no fuel and iron brakes.

JFT

Yes it's a Euro spec RS. Half cage only. Carbon Seats. Plexi window. Xenons. Cruise Control. Nothing else.
