Default GT3 Gas Guzzler Tax?

I noticed, on Porsche's Web site, that the "estimated" fuel mileage for the GT3 is currently 15 city, 20 highway, and 17 combined. That's way under the 22.5 combined threshold for the gas guzzler tax. Will the $3k tax show up on my window sticker next year - like it did on my 2007 RS-4 - or does Porsche not do it that way? I looked through the 2013 and 2007 Gas Guzzler lists and didn't see any Porsches. The Turbo S Cab says 17/24 - so turbochargers are more efficient than revolutions.

I speculate that might be a reason that Porsche won't build "as many as they can sell." It may also mean that high RPM engines will all be replaced by turbocharged engines over the next few years. It's already happening at BMW and Audi.

Good question. I found this info on the EPA site:

The Gas Guzzler Tax for each vehicle is based on its combined city and highway fuel economy value. Manufacturers must follow U.S. Environmental Protection Agency (EPA) procedures to calculate the tax. The calculation uses a formula that weights fuel economy test results for city and highway driving cycles (the combined value is based on 55% city driving and 45% highway driving). Fuel economy values are calculated before sales begin for the model year. The total amount of the tax is determined later and is based on the total number of gas guzzler vehicles that were sold that year. It is assessed after production has ended for the model year and is paid by the vehicle manufacturer or importer.

Based on Porsche's numbers of 15city/20hwy the calculation works out to 17.25 which, according to the sliding scale the EPA uses, would result in a GG tax of $3000. However, the way I read the above, since the tax is also based on the number of vehicles sold, the tax might be less due to low volumes and perhaps no tax would be assessed the first year. A plus for early adopters? Maybe Porsche would estimate the tax to assess the buyer or, OTOH, perhaps choose to pay it tax themselves. More wishful thinking?

FWIW, the highway MPG for both of those models is better than the GT3 but probably not enough to avoid the tax based strictly on the numbers. So maybe Porsche IS picking up the tab.....

Our 2013 Cayenne GTS didn't have one, maybe a different category?. It's rated at 15/21.

Maybe, although the current rates have been in effect since 1991....

The gas guzzler tax is such bs. If a car has "poor" mileage it will require more fuel and the more fuel you buy the more taxes you pay. And also why are trucks exempt?

Right.


I figure if you are in the market for a GT3 and want that 9,000 redline then $3 extra is like. Fock it! Right? Not to change the subject but I can't believe what kind of amazing mileage my 991 C2S is getting. Amazing. I saw 27.5 the other evening and that was averaging 75 on the freeway.

Sorry for the tangent.

I don't want to guess but I'm hoping Porsche eats it like it does on other models. I don't remember a gas guzz tax on my buddies 2010 GT3. Maybe ask the 997 guys if anyone with a 997 GT3 RS had the tax. I think the window mpg #'s are similar.

Exactly. I cannot understand how GT3 achieved such a poor mileage on a light car with Direct Injection engine, which is unbelievably economical in C2S. I understand that the gearing is shorter, but it's not that short - it's taller than in M3, for example, and that one gets 14/20 on a much heavier car and non-DI engine that uses mollases for engine oil (10-60).

There you have it.

That's what I wanted to see.

A fair price to pay for owning a 997.2 GT3 RS.

Well, I believe our 991 C2S 3.8 shares only 2 parts total with that 9,000 rpm GT3 motor. A small price to pay for an additional 75 hp. ? Maybe.
