2019 Chevy Corvette ZR1 101HP Redesign, Release Date, Price, & Spy Shots – When you study the amount of horsepower a car produces, you see how much power the car makes at the crank. True-world horsepower is lower and is usually calculated at the wheels employing a dynamometer (dyno). The decrease horsepower number is attributed to drivetrain reduction – power lost by way of friction and rotational inertia. Each and every car suffers some drivetrain decrease, which includes the 2019 Chevy Corvette ZR1. Earlier in the week Hennessey Performance unveiled a video of a few staff members driving the ZR1 and last night the upgraded tuner introduced a video of the supercar on the dyno.
The ZR1 suffers about a 13-percentage drivetrain damage. At the crank, the ZR1’s supercharged 6.2-liter LT5 V8 engine produces 755 horsepower and 715 pound-feet of torque. However, at the wheels, the ZR1 can make 654 hp and 645 lb-ft of torque. Which means 101 horsepower disappears expected to drivetrain damage. Now, that doesn’t suggest the ZR1 is a slouch. The 654 hp at the wheels indicates the ZR1 can hit 60 miles per hour or so from a standstill in 2.85 seconds and hit 100 mph in 6. seconds. The supercar is capable of completing a quarter-mile race in 10.6 seconds at 134 mph.
The ZR1 with “just” 654 hp still packed sufficient impact for Hennessey workers to sing out praise about the high-performance Corvette. Allergic reactions from the earlier video ranged from “For a stock vehicle this is truly impressive” to “I’d get rid of my certificate in about a few days.” And it is not like drivetrain reduction only affects the ZR1. Automobiles with SAE International horsepower rankings show the horsepower at the crank. These vehicles lose horsepower via drivetrain reduction just like the ZR1.
If you are not happy with the drivetrain decrease, Hennessey already has three performance offers available for the ZR1 ranging from the HPE800 to the HPE1200. The base package creates 850 hp and 715 lb-ft of torque. The HPE1200 pack creates an absurd 1,200 hp and 1,066 lb-ft of torque thanks to a host of adjustments that include a 7.0-liter engine upgrade and a high-flow supercharger. That should make up for any frustrating drivetrain decrease.
