The Carpocalypse has meant the end of many storied automotive nameplates, performance variants and others — some before they even had a chance to live. Here's our list of the twelve most important vehicles killed by the Carpocalypse.

All the important details, including birthday, time of death, and cause are in the coroner's report below.

Cobalt SS Sedan
Introduced: 2004
Time Of Death: May 2009
Reason: When GM axed nearly every performance trim the Cobalt SS Sedan, despite a small but rabid following, was also on the chopping block.

Acura NSX
Introduced: 1990 originally, still in concept phase
Time Of Death: December 2008
Reason: According to Honda Chairman Takeo Fukui it's so the company can focus on green technology.

Chevy Impala SS
Introduced: 1961
Time Of Death: May 2009
Reason: Quite possibly the least likable of the defunct GM performance trims, we won't miss it much.

Mercury Sable
Introduced: 1986
Time Of Death: May 2009
Reason: Though Ford has high hopes for the new Ford Taurus, they don't want to weigh down the excitement with the Mercury version.

Camaro Z28
Introduced: 1967 originally, still in concept phase
Time Of Death: March 2009
Reason: The 2010 Chevy Camaro is, so far, a hit. For the moment, coming out with a 400+ HP Camaro while you're creating a new, green GM, didn't seem like a good use of money. We'll always have the SS.

Pontiac G8 GXP... And Every Other Pontiac
Introduced: 2008
Time Of Death: April 2009
Reason: With Pontiac dead the beloved G8 GXP is no more. Also gone, the beloved Pontiac G8 ST and the beloved-by-some Pontiac Solstice. No one, though, will miss the G3.

Toyota A-Bat
http://jalopnik.com/5210418/doa+bat-toyota-hybrid-truck-concept-dead
Introduced: Concept revealed December 2007
Time Of Death: April 2009
Reason: Designed to compete with the not-particularly-popular Honda Ridgeline, the Toyota A-Bat was going to be a car-like hybrid truck. Instead, it died so that more Scions could live.

Cadillac STS-V
http://jalopnik.com/140692/between-the-lines-autoweek-on-the-cadillac-sts+v
Introduced: 2006
Time Of Death: May 2009
Reason: Like many other GM products, the every performance trim>SSocalypse also claimed the non CTS-V Caddy performance models.

GT-R Sedan
Introduced: Rumored Concept
Time Of Death: April 2009
Reason: The longstanding rumors of a GT-R based Infiniti collapsed because, in the business climate, it wasn't a priority. I mean, c'mon, how old is the Altima?

HHR SS Panel
http://jalopnik.com/cars/jalopnik-reviews/chevrolet-hhr-ss-part-1-334563.php
Introduced: 2007
Time Of Death: May 2009
Reason: Though a Retro-styled, tubrocharged panel van appeals to us, it wasn't worth the investment for GM.

Diesel Ram 1500
Introduced: 1981
Time Of Death: June 2009
Reason: With a bankrupt company a diesel-powered light-duty truck isn't a priority.

GMC TopKick
http://jalopnik.com/5283259/gm-kills-ironhide-ceases-production-of-topkick-kodiak
Introduced: 1980
Time Of Death: June 2009
Reason: GM's medium-duty truck offerings weren't as crucial as Ford's and, with no super interested buyers, the Kodiak and TopKick finally kick the bucket.
