Cadillac enjoys exclusive use of high compression version of GM’s 6.0 liter V8, and this is the only engine available in the EXT. the special Vortec 6000 produces 345 bhp, which is 25 more horses than Chevrolet’s version, and 50 more than the Lincoln Black Wood’s V8. The extra power comes from high flow aluminium cylinder heads and a 10.0:1 compression ratio, revised cam shaft profile; 75 mm throttle body and less restrictive exhaust. The price for this power is a 12 mpg city rating. The 6.0 liter gets a heavy duty version of GM’s Hydra Matic 4L60-E electronically controlled 4 speed automatic transmission. The EXT comes with full time all wheel drive and a traction control system. The All wheel drive uses a vicious coupling transfer case to constantly adjust power to the front or rear wheels, maximizing traction. The system is always on and requires no input from the driver, but without a low range EXT is not a candidate for serious off roading antics. Also monitoring the EXT’s dynamics are Stabili Trak, ABS and a computer controlled Road Sensing Suspension (RSS) System.
The ride is made in a very beautiful and unique way. Next Year, when loyal Cadillac customers pull up to the dealership and see the EXT sitting next to the 2003 CTS sedan and the striking XLR-2 seat roadster, they are going to have all of their preconceived notions about Cadillac turned upside down. Probably just the way Cadillac wants it.
