While track testing the latest Z06 Corvette, Gary Gastelu of Fox News experienced an issue that’s becoming a trend for Chevrolet’s supercharged sports car: engine failure.
“After a few lapping sessions, the engine in mine unceremoniously called it quits,” reports Gastelu in his review.
Unfortunately the cause is still unknown in this instance, though engine failures are increasing in occurrence for the 650-horsepower Corvette.
Late last year, Corvette Forum’s member “Lawdogg149” had the LT4 V-8 in his Z06 implode after only 891 miles on the clock. The failure was with the valvetrain, though root cause of the failure wasn’t reported. GM instructed the dealer servicing the car to return the engine to the mothership unopened for further analysis. The Z06 received a new powerplant covered under warranty.
GM Authority stated as many as three failures have been mentioned on Corvette Forums as of June 2015.
Other issues have been reported, such as reduced power after hard launches or track use, in order for the engine to “survive for 100,000 miles as well as allow the Z06 to meet stringent US emissions regs,” reported Jalopnik last year.
