Gas Guzzler tax?

[OldTimer]

If it has skip shift like the corvette it will not have the gas guzzler tax. For those that don't know, the corvette has skip shift which at low rpm's forces you to shift from 1st directly to 4th. You can buy a $25 part and install it to by pass the skip shift. If that is common knowledge here, sorry!

The 2009 Corvette has the gas guzzler tax. Yes, Camaro does have the skip shift though. Maybe this is the ZR1? The pdf doesn't specify...

I had totally forgot about that!

Our members ROCK!

No it doesn't. I just bought one last month. CGM to be exact and there was no gas guzzler tax.

You bought a ZR1? Or one with a LS3?

LS3

Yea, I'm thinking that the one listed is the ZR1. It just says Corvette with 6.2L V8 with a M6 transmission so that could be either one.

Using that updated info in my earlier post... divide the numbers GM gave in the last IDL by the correction factor will give the old EPA numbers.
so...
15/22 man = 16.7/28.2 = 21.875
15/23 auto = 16.7/29.5 = 22.46

But both of those are still just shy of the 22.5 required. Maybe there's some rounding error in there or something or maybe they've gotten the results a smidgen higher (all it would take is 16 city to make it meet the cutoff). I guess we'll see soon enough when the EPA numbers become officially official.

Calculation Technique
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.

EPA and manufacturers use the same test to measure vehicle fuel economy for the Gas Guzzler Tax and for new car fuel economy labels. However, the calculation procedures for tax and label purposes differ, resulting in different fuel economy values. This is because an adjustment factor is applied to the fuel economy test results for purposes of the label, but not for the tax. The adjustment is intended to help account for the differences between “real-world” and laboratory testing conditions.

EPA conducts fuel economy tests in a laboratory on a dynamometer (a device similar to a treadmill). Laboratory conditions can be different from real world conditions for such parameters as vehicle speeds, acceleration rates, driving patterns, ambient temperatures, fuel type, tire pressure, wind resistance, etc. EPA studies indicate that vehicles driven by typical drivers under typical road conditions get approximately 90 percent of the laboratory test-based city miles per gallon (mpg) value and approximately78 percent of laboratory highway mpg value. This difference is referred to as “in-use shortfall.” To account for the in-use shortfall, the city and highway mpg values listed in Fuel Economy Guide and shown on fuel economy labels are multiplied by 0.90 for the city test and 0.78 for the highway test. However, the combined city and highway fuel economy that is used to determine tax liability is not adjusted to account for in-use shortfall, so it is higher than the mpg values provided in the Fuel Economy Guide (www.fueleconomy.gov) and posted on the window stickers of new vehicles.

Going by these numbers 15/23 EPA MPG could get by with no GG tax with only very slight rounding that wouldn't show int he final numbers while 15/22 EPA MPG might be able to avoid the tax depending on the decimal places and rounding method used. This also gives me 20.5 for the ZR1, the EPA probably has an extra decimal place or two on their estimates that I don't have accounting for their 20.4 listed. Also note that the Z06 does not incur the GG tax with it's 15/24 rating.

I have a friend of mine that is purchasing an SRT8 Challenger and he forwarded the order sheet to me to take a look at. It has the prices of every option in the car and has the Gas Guzzler tax at $1300 MSRP

[CamaroSpike23]

is that EPA calculation technique the updated one that the EPA now uses? that does 80mph highway instead of the 55/60

That's using the current testing methods but as mentioned the gas guzzler mpg's do not include the correction factors that the sticker mpg's do.

i am pretty sure that the SS will get the gas guzzler tax.


the SRT8 gets it and the SS has a bigger engine with more power.




so why not?

Because it's based on fuel consumption, not engine size or horsepower and the Camaro is more fuel efficient than the SRT8.

Don't forget the Six Speed Manual and Six Speed Auto on the Camaro. Also Camaro will be lighter in weight than the Cahllenger.
