Come one, come all: It's time for a rousing edition of Guess That Engine. Know a piston skirt from a pressure sender, a con rod from a cap screw? Here's a slew of chances for you to prove it.

Auto shows usually have a healthy dose of engine porn, but the L.A. show had more than most. The eight powerplants in this gallery were found on the show floor, and each is available in a car sold (or about to be sold) to the American public. The only thing they have in common is that they looked cool on the stand.


Answers are on the right side of the page, along with a car that the engine is installed in. Be a sport and try not to peek, huh?

(The flat six seen here isn't part of the game because it's too easy — it lives in a Porsche 911. That said, if you can figure out which 911 it goes in, we might be impressed.)
