Borrowing the supercharged 6.2-liter V8 from the CTS-V – albeit with significant upgrades – the CT5-V Blackwing pumps out an absurd 668 horses (498 kW) and 659 pound-feet (893 newton-meters). That allows it to hit 60 in just 3.7 seconds and continue on to a top speed of around 200 miles per hour (322 kilometers per hour).
Although the CT5-V Blackwing uses the same supercharged V8 as its predecessor, the modifications are plentiful. The CT5 has a larger supercharger (1.7 liters, to be exact), new pulleys, aluminum cylinder heads, titanium intake valves, and 46-percent better airflow. And for the pursuits, there is a manual transmission. A Tremec six-speed manual comes standard on the CT5-V Blackwing (as well as the CT4-V Blackwing), with features like no-lift shift and rev-matching. The optional gearbox is a 10-speed automatic that Cadillac says shifts faster than competitors' dual-clutch transmissions. Notably, the 3.7-second sprint to 60 happens with the autobox, while the manual will be a touch slower off the line.
Underneath, the CT5-V Blackwing adopts GM's fourth-generation Magnetic Ride Control system. Already one of our favorite setups, the latest version includes upgrades to the front and rear suspension systems (hollow stabilizer bars, higher-rate bushings, etc.), improving both track handling and on-road comfort. And in both models, power travels to the rear wheels exclusively.
The CT5-V Blackwing gets standard Michelin Pilot Sport 4S tires designed exclusively for this model, measuring at 275/35R19 in the front and 305/30R19 in the rear. That super-sticky rubber wraps around Blackwing-exclusive forged 19-inch wheels, and those wheels hide a set of optional carbon-ceramic brakes pads that help shed an extra 53 pounds (24 kilograms) versus the standard steel brakes.
All that performance will cost you $84,990 for the base Cadillac CT5-V Blackwing before options.
