PZEV

subaruWe recently helped our son Steve buy a used car. We settled on a Subaru Forester, and when we got it home, I noticed a label on the back of the vehicle that said, PZEV. In small letters below this, it said, “partial zero emissions vehicle.”

It reminded me of my days as a teenager when status was very important. A car could be an RT, or a RT/X, which was presumably even better than a plain old RT. Nowhere that I could remember, did anyone make clear what the difference was between the two models, but I can still remember thinking I’d take the RT/X over the RT any old day.

So I was interested to see an acronym on Steve’s car that was actually spelled out. And naturally, once I read it, I tried to figure out what the heck PZEV meant. We all have an idea what a zero emissions vehicle would be. It would take you down the road with no emissions of any sort. Kind of contrary to Newton’s laws, but maybe it is a target worth shooting for. Then there would be a 100% emissions vehicle, which I envision to be a cheap barbecue grill into which gasoline is dumped and lit. This “vehicle” put 100% of its emissions into the atmosphere, and didn’t move an inch.

A partial zero emission vehicle, then, would be somewhere between zero and 100%, which I would argue is the right category for every car that has ever been made.

Wikipedia to the rescue! “A partial zero emissions vehicle is a vehicle that has zero evaporative emissions from its fuel system, has a 15-year (or at least 150,000-mile) warranty on its emission-control components, and meets SULEV tailpipe-emission standards.” So a PZEV is a pretty cool thing after all. I wonder when the PZEV/X model will be coming out.

    Ted the X is often slapped on the end to indicate luxury add on features. In bygone years RT (road/track) was mostly… I think soley coined and used for dodge/mopar vehicles. Chevy used the SS badge. Ive honestly never seen the X on the end of Mopar vehicles with one exception. Could you be remembering the PLymouth GTX? For that they took GT(gran tourismo) and slapped an X on the end purely because it sounded cool. It was coined to be “the gentlemans” sports car and the 426 hemi version could hit 60 in 4.8 seconds with 13 second quarter miles… Thats pretty amazing for those heavy cars. The 440 version took a dismal (heh) 6.5 seconds to reach 60. Anyways sounds like a cool car. I teresting memory too. Peaked my interest. If there is an RTX Mopar Id love to see it.
