Extract of Wikipedia about using that engine
Omega V8.com
The V8.com concept car project was meant to be a "mobile office" it was built on Omega station wagon which was elongated by 130mm, to provide more space for the passengers and additional equipment; containing separate 9.5 inch LCD screens for all passengers, internet access and integrated video conferrence mobile phone system with separate cameras and microphones providing passengers hands-free operation. Additionaly the car was equipped with Xenon headlights, and Advanced Frontlighting System (AFS), automatically adjuststable to the road conditions.
Hence the name it was powered by a GM LS1 V8 engine.
The car debuted at Frankfurt Motor Show in 1999.[8]
[edit] Omega V8
Opel was planning to upgrade it's flagship Omega model with powerful GM LS1 V8 engine used in Chevrolet Corvette.
Unlike V8.com which was the concept car, this model was planned to go into the serial production.
Omega V8 was showed publicly for the first time at 70th Geneva Motor Show (March 2 - 12, 2000). A V8 engined version was to be put on sale autumn 2000.[9]
Cancelling
The reasons for cancelling production plans were concerns about whether the engine was vollgasfest (German, "Full throttle resistant") - the engine might overheat and be damaged if driven flat out on the Autobahn for long periods of time
reallly a great shame would of been a fun bit of kit and would of put the omega as a serious contender against 540is & E430s
