The Cadillac STS ((S-Series Touring Sedan) makes use of a whopping 300 horsepower using a 32-valve Northstar V8 Cadillac engine, which can easily take the car from zero to 60 mph in just 7.1 seconds. The Northstar V8 is light in weight making use of an aluminum block and cylinder head, with four valves for every combustion chamber. The valve are moved up and down by dual overhead camshafts, driven by quiet durable chains.
The Northstar V8’s intake manifold helps to efficiently channel air into the combustion chambers with outstanding effectiveness. Features of this one-piece manifold design are patented. In fact, there is a total of 16 U.S. government patents in the Cadillac Northstar engine.
In addition the Northstar Engine features a “limp-home” mode that keeps the engine operating without engine coolant. “Limp-home” allows the engine to continue running by alternately delivering fuel to only four of the eight cylinders. The four remaining cylinders do not fire, but continue to pump air, cooling the engine and allowing you to safely drive at 50 mph up to 50 miles for help. This of course is in conjunction with the two cooling fans that run in tandem or singular mode to provide quiet cooling in different driving conditions.
The Northstar features OBD II, which became mandatory by the year 1996. For all practical purposes OBD11 (on board diagnostics) became the universal diagnostic hookup for all cars, worldwide.
It also features a liquid cooled alternator for a quiet charge as well as longer part life.
The Caddy Seville was designed to travel up to 100,000 miles before a scheduled tuneup thanks to long life components like platinum tipped spark plugs and a distributor-less direct fire electronic ignition system.
