2017 Chevrolet Camaro ZL1 Shows Off the Line Lock Feature at Goodwood
Prior to making a quarter mile drag strip run in the 2017 Chevrolet Camaro ZL1, the driver will likely want to smoke the tires in order to make sure that the tires are clean and that the rubber is warm, sticky and ready to offer the best traction possible. The problem is that for some people – especially those with a manual transmission – doing a good burnout can be a bit tricky. The new Camaro ZL1 makes it a little easier with a new line lock feature that helps keep the supercharged muscle car in place while the rear tires are roasting.
To introduce this feature, General Motors boss Mark Reuss did a big, nasty burnout in front of the Goodwood Festival of Speed crowd.
2017 Camaro ZL1 Line Lock
Before getting into how the line lock system works in the 2017 Chevrolet Camaro ZL1, a quick explanation of line lock for someone who might not be familiar with the system.
The braking system in the 2017 Camaro ZL1 (and every other modern car) works via a system of fluid-filled lines. When you depress the brake pedal, the system pushes brake fluid into the brake calipers, which squeezes the brake pads against the rotor. When you let off of the brake pedal, that fluid is allowed to flow back out of the calipers, thus releasing the pressure on the rotors. With a line lock system, you depress the brake pedal and send the fluid to the calipers, but when you let off of the brakes with the line lock engaged, the fluid in the front brakes lines is prevented from leaving the calipers – thus locking the front brakes. When you let off of the brake pedal with line lock engaged, the fluid is permitted to leave the rear calipers so there is no braking pressure applied to the rear wheels during the burnout, but until the line lock system releases the front brake system – those wheels will remain stationary.
In the 2017 Chevrolet Camaro ZL1, the line lock system is activated via the driver information system when the car is in Track mode and the Launch Control page has been chosen – while the transmission is in D for automatic models or 1st gear for manual transmission models. When line lock is activated, the information screen in the gauge cluster prompts the driver to apply the brakes and when 80% pedal pressure is reached, line lock is activated. After that, he or she can let off of the brakes, using their left foot to operate the clutch (when applicable) while the right foot operates the throttle.
The Camaro ZL1 line lock will keep the front brakes locked for 15 seconds, but if the driver pushes both center control buttons on the steering wheel, the front brakes will release and let the car roll forward, all with the rear tires ablaze.
The video below shows a 2017 Camaro ZL1 at the Goodwood Festival of Speed with Mark Reuss at the wheel. He shows off the line lock system with a short, smokey burnout while stationary and then he lets the car roll – with the tires smoking hard as the 640hp Chevy muscle car speeds away.
