This post, from SRT Blog really caught my eye:

It seems as though the Dodge Ram SRT10 will go out on top like most sports stars do according to a news report from KnightRidder. Dodge plans to stop production on the worlds fastest production truck that includes a six-speed manual transmission and 8.3 liter V-10 engine borrowed from the Dodge Viper. The engine generated 500 horsepower and had a top speed of over 150 mph. Dodge only sold about 2,000 units a year annually since it started production in 2004.
