Which one of these GM legends is your favorite?
Can a mid-engine sportscar lose to a sports sedan during a performance test? You might be able to if the sports sedan is the Cadillac CT5V Blackwing, which combines decades worth of GM performance engineering and a supercharged engine. The new C8 Corvette sports car is an engineering marvel, but it can handle the Cadillac CT5-V Blackwing, the most powerful sports sedan ever made. The U-Drag drag race was held by Edmunds to find out. This form of drag racing tests competitors’ straight-line speed and braking performance as well as their handling. The best GM product may win!
You don’t need to know much about the C8 Corvette, because the C7 was a different vehicle. If you’re counting, the engine is now located in the middle of the vehicle, just like a Ferrari. There’s also no manual transmission. Tremec’s 8-speed dual-clutch auto is instead, which makes the C8 Corvette more powerful than any Corvette before.
This high-tech transmission is coupled to the familiar Chevy LT engine. It’s now called the LT2 and maintains the pushrod design of the many Chevy V8s that came before it. The 6.2-liter LT2 produces 490 horsepower (365 kilowatts) as well as 465 lb/ft (630 Newton meters) of torque.
The Cadillac CT5-V Blackwing is the latest Cadillac sports sedan. It’s designed to take on Chevy’s supercar. The new pinnacle in performance does not use Cadillac’s short-lived twin turbo Blackwing V8 engine. Instead, it uses an upgraded version of the supercharged 6.2 liter LT4 engine of the C7 Corvette Z06. The LT4 engine produces 668 horsepower (498 kilowatts), and 659 lbft (893 Newton meters) of torque in the CT5-V Blackwing.
