The biggest update for the refreshed 2026 Corvette is its redesigned interior, which includes three displays, traditional HVAC switches in lieu of the wall of buttons, and new colorways, finishes, and materials. However, the Corvette gets a few other upgrades for 2026, one of which is the new PTM Pro drive mode.
Performance Traction Management (PTM) first debuted on the C6 ZR1 in 2010 and has been part of the Corvette ever since. As its name implies, it manages traction to optimize performance and stability without the brakes being too intrusive when the system detects wheelspin. It can apply brakes when it needs to, but it can also reduce engine torque, adjust damping if equipped with Magnetic Selective Ride control, and control torque distribution via the eLSD when equipped.
PTM offers multiple modes in the C8 Corvette. From its debut in 2020 through 2025, those modes were Off, Wet, Dry, Sport, Race 1, and Race 2. Now, the new PTM Pro mode, which comes in all 2026 Corvette variants, turns off traction control and electronic stability control entirely while leaving ABS on. On the E-Ray, it leaves front axle controls active, as well. The idea is to minimize intervention from “nannies” and give the driver maximum control.
PTM Pro mode is best left for track use. The PTM Sport and Dry modes are more suitable for on-road performance driving. Race 1 and Race 2 are similar, StabiliTrak is turned off in both modes. The difference is Race 1 still limits engine power to the same as Sport mode, while Race 2 mode allows for maximum engine power, even when cornering.
As a reminder, the 2026 Corvette is motivated by different powertrain configurations based on variant. The Stingray is propelled by the naturally aspirated 6.2L V8 LT2 engine, developing 490 horsepower and 465 pound-feet of torque. The E-Ray adds a front-mounted electric motor, boosting power to 655 horsepower and providing AWD. The Z06 cradles the naturally aspirated 5.5L V8 LT6, cranking out 670 horsepower and 460 pound-feet. Finally, the new-for-2025 ZR1 is powered by the twin-turbocharged 5.5L V8 LT7 gasoline engine, developing 1,064 horsepower and 828 pound-feet of torque.
All 2026 Corvette variants are based on the GM Y2 platform, which is produced exclusively at the GM Bowling Green Assembly Plant in Kentucky.

A step in the right direction for sure. However, how about making a few changes other than computer programming. I. E. base engine should be putting out 525 HP, front head lights are due for a redesign as well as the back fascia including the Camaro tail lights. From paper to now those items are ten years old.
Well, there is a new V8 coming in 2027. It will probably appear in the C7 first
You wouldn’t even notice a 5% change in HP on the street. The only real benefit would be bragging rights for bench racing.
Leave the headlights and back fascia alone. Those changes should be left to the C9.
Can’t wait to see all the self-important “expert” drivers turn on PTM Pro on the street and drive into the forest.
