Filed under: Etc. , Supercars , Chevrolet , GM For many, General Motors' Mr Stephens' Engine Shop online game is full of metallic looking stuff, none of it discernibly purposeful. What you're working with are extracted parts of the LS9 engine that powers the Corvette ZR1. Unless your ZR1 is in the shop for catastrophic engine failure, these components aren't usually seen out on their own. The General's little game has you correctly identify the major pieces and awards a prize after three rounds of correct answers (or lucky guesses). So many people, not just kids, are ignorant about the inner workings of the complex machine known as the car, so we applaud this effort to shed light on the mysteries that lie beneath the bodywork. Watch out for that fuel rail, we found it a little tricky to place. If anything, we're eager to get home and have the young ones begin learning auto anatomy. Thanks for the tip, Eden!

Filed under: Etc. , Tech , Videos , Chevrolet , GM Automobile Magazine was invited into General Motors Performance Build Center to watch and lightly assist in the buildup of a ZR-1's internal combustion heart. It takes four-and-a-half hours of real time to go from a bare block to a fire-breathing, supercharged LS9, but through the magic of sped-up video, it only takes seven minutes of your life. You won't come away with anything productive for that time, unlike the people in the video, who get the pleasure of creating a small-block V8, but it's a neat picture of how it all comes together. We just hope that some other poor sucker gets the motor that the magazine intern fiddled with. Video posted after the jump.

Filed under: Tech , Supercars , Chevrolet When Chevrolet officially announced the new Corvette ZR1 just before the Detroit Auto Show this year, it hadn't yet finished the certification of its new power-plant, the supercharged LS9. At that time, all the engineers would tell us was that the supercharged 6.2L V8 would produce a minimum of 100hp/L or 620 hp. Three months have passed since we got our first official look at the LS9 and the numbers are now in. According to GM, the LS9 has now been SAE Certified at 638 hp and 604 lb-ft of twist. The official EPA fuel economy testing hasn't been finished and for people who buy a ZR1 it probably won't matter anyway. Nonetheless, GM expects the LS9 to be the most fuel efficient 600+hp engine in the world, a dubious distinction if ever there was one. A special team of technicians will be hand-building and testing the LS9 at GM's Performance Build Center in Wixom, Mich. Check out the articles below for all the details on the ZR1 and...
