Continuing Cadillac's styling metamorphosis is the new rear-wheel drive STS-V flagship with an all-new 4.4-liter version of Cadillac's Northstar V-8. General Motors is showing off their new six-speed automatic transmission on an engine that ponies out 440 horsepower and 430 lb-ft of torque 32-valve dual overhead cam (DOHC). The dual overhead cam (DOHC) V-8 engine delivers the highest horsepower rating of any production Cadillac engine to date.
Incorporated as part of the package are my favorite brembo disc brakes, 18-inch front, 19-inch rear Pirelli run-flat tires which you'll need on the 0-60 in less than 5 seconds. Other pluses are advanced Performance Algorithm Shifting (PAS) and Driver Shift Control (DSC). PAS lets the electronic transmission controller override the automatic gear selection during closed throttle high lateral acceleration maneuvers, rapidly downshifting with the release of the torque converter clutch for smooth powering up when the throttle is reopened. Driver Shift Control allows the driver to sequentially shift gears manually via the gearshift lever.
A larger, polished stainless steel wire mesh front grille that enables the required additional airflow for engine heat dissipation. The wire mesh grille not only signifies the sedan as a V-series, but is also a heritage cue, wire mesh grilles were applied on the Cadillac V-16, the standard bearer of luxury and performance in the 1930s;
A new, lower front fascia that incorporates a larger lower grille (also wire mesh) for increased cooling capability; brake ducts for front caliper and rotor cooling; and splitter to counteract lift created by larger grille openings.
A new lower rear fascia that facilitates smooth airflow under the vehicle for improved cooling; Lower rockers that visually bridge the lowered front and rear fascias.
A specific, fluidly sculpted hood designed to provide space for the engine's supercharger.
Ten-spoke, flangeless, painted aluminum alloy wheels that assist in brake cooling. Front wheels are 18 x 8.5 inches; rear wheels are 19 x 9.5 inches.
A higher, more rearward-positioned rear spoiler that enables balanced aerodynamic downforce with the front splitter; and V- series badging prominently displayed on the vehicle's rear decklid and front doors along with "Supercharged" block lettering on the doors.
