We recently reported on this barely-used 2022 Cadillac CT5-V Blackwing that’s for sale in Florida and we noticed something peculiar about the vehicle’s digital gauge cluster that we had previously overlooked: the tachometer showed a redline of 4,500 RPM as opposed to the regular 6,500 RPM redline. Having looked into it, it turns out the super sedan’s instrument panel shows a lower redline until the 500 mile break-in period is completed.
It’s our understanding that this is a first for any production GM vehicle powered by the supercharged 6.2L LT4 V8. Notably, the CT5-V Blackwing application sees the highest output from the blown Small Block with a rating of 668 horsepower and 659 pound-feet of torque compared to the 650 horsepower and 650 pound-feet of torque in the Chevrolet C7 Corvette Z06 and Chevy Camaro ZL1, or the 640 horsepower and 630 pound-feet of torque in the third-generation Cadillac CTS-V.
Edit: It’s worth clarifying that this is actually a moving redline that’s based on engine temperature, a feature found on some other GM vehicles, including Corvette models. Once the break-in mileage has been reached, the tachometer will display a 6,500 RPM redline. However, upon vehicle startups thereafter, the redline adjusts dynamically based on engine temperature, and will reach 6,500 RPM once the engine reaches operating temperature.
Additionally, when the vehicle engine is less than 158°F (70°C) – or if the vehicle odometer value is less than 500 miles (805 kilometers) the shift indications are not displayed.
If GM ever discovered that a different temperature point or mileage break-in was optimal for the vehicle’s performance or lifespan, it’s theoretically feasible for The General to introduce revise these features since the Global B electronic architecture that serves as the central nervous system of the CT5-V Blackwing allows for such updates. And, since Global B enables over-the-air (OTA) updates, among other things, such an update could be performed without even taking the vehicle to the dealership.
Nevertheless, the break-in procedure for the 2022 Cadillac CT5-V Blackwing – as per the owner’s manual – is as follows:
- Avoid full throttle starts and abrupt stops.
- Do not exceed 4000 engine rpm.
- Avoid driving at any one constant speed, fast or slow.
- Do not drive above 129 km/h (80 mph).
- Avoid downshifting to brake or slow the vehicle when the engine speed will exceed 4000 rpm.
- Do not let the engine labor. Never lug the engine in high gear at low speeds. With a manual transmission, shift to the next lower gear. This rule applies at all times, not just during the break-in period.
- Do not participate in racing events, sport driving schools, or similar activities during this break-in period.
- Check engine oil with every refueling and add if necessary. Oil and fuel consumption may be higher than normal during the first 2 414 km (1,500 mi).
- To break in new tires, drive at moderate speeds and avoid hard cornering for the first 322 km (200 mi). New tires do not have maximum traction and may tend to slip.
- New brake linings also need a break-in period. Avoid making hard stops during the first 322 km (200 mi). This is recommended every time brake linings are replaced.
- Should the vehicle be used for racing or competitive driving (after break-in), the rear axle lubricant must be replaced beforehand.
While it may be a challenge to abide by the restricted usage laid out in the above break-in procedure, doing so will keep the vehicle’s warranty in-tact and should increase the likelihood of a long, trouble-free life.
