Cadillac has unveiled the 2016 CTS-V sedan, ahead of its official debut at the 2015 Detroit Auto Show, and the new third-generation CTS-V packs a wallop: under the hood is a supercharged 6.2-liter LT4 V-8, generating 640 horsepower and 630 lb-ft of torque (essentially a slightly downrated version of the 6.2 liter LT4 found in the 2015 Chevrolet Corvette Z06), enabling a 0-60 mph sprint time of 3.7 seconds and a top speed of 200 mph. Those power figures leave the new CTS-V's main competitors in the dust, with the BMW M5 and Mercedes-Benz E63 AMG able to muster 575 and 577 horsepower in their most robust trims. Keeping the power under control are a Magnetic Ride Control active damping system (featuring a 40-percent increase in responsiveness)and a 25-percent increase in structural stiffness improves overall handling and steering. A high-performance Brembo brake package comes standard, along with 19-inch alloy wheels and Michelin Pilot Super Sport tires. Expect the CTS-V sedan to hit showrooms in the summer of 2015.
