The 2011 Cadillac CTS-V Coupe will use the most powerful engine ever offered by the automaker. Find out the 0-60mph time inside.

The 2011 Cadillac CTS-V Coupe will use a supercharged 6.2-liter V8-engine producing 556 horsepower and up to 551 ft-lb of torque, according to the automaker.  Cadillac will introduce the car to the public next week at the 2010 North American International Auto Show in Detroit.

Using "the most powerful engine" Cadillac has ever offered, the car is capable of a 0-60mph time of 3.9 seconds.  Mated to the LSA engine is a choice of transmissions, including a Tremac dual-disc six-speed manual and a Hydra-Matic six-speed paddle-shift automatic.

With bigger braking needs on the CTS-V Coupe, Cadillac turned to Brembo.  The well-known brake manufacturer is supplying six-piston calipers at the front, and four-piston calipers at the back.  "Slotted and vented rotors," built from iron and aluminum, were also used.  Cadillac's Magnetic Ride Control suspension system is a standard feature.

Outside, customers will notice the uniquely-shaped grille, built to maximize air intake.  Compared to the normal CTS Coupe, differences can be seen on the front and rear fascias, and the bulging hood.  Dual exhaust pipes are centered on the car.  On the CTS-V, Cadillac will use a choice of painted or polished 19-inch aluminum wheels wrapped in Michelin Pilot Sport 2 tires.

Recaro seats are used inside the 2+2 car, and are 14-way adjustable.  A new color option, Saffron, is available on the interior, with a faux suede microfiber material used on the seat inserts, shifter, and steering wheel.  The standard infotainment package includes a 40-gig hard drive, retractable screen, navigation system, and Bose surround sound.

Sales for the 2011 Cadillac CTS-V Coupe will begin this summer.
