The 2020 Corvette C8 Stingray is one of the most exciting cars of this year from the American manufacturer. The Chevrolet Corvette is a legend in the American automotive industry, and rather than just having a fan base, it has garnered a cult following. This vast popularity and cult following for this car over the years are because of the muscle car’s performance with quick acceleration and high straight-line speeds. These are also complemented by sportier design on the exterior and the interior with many features as standard. The 2020 C8 Stingray is the first Corvette with a brand new mid-engine platform to power the muscle car. The power unit is a naturally aspirated 6.2-liter LT2 V8 engine which has been tuned to produce 495 hp and has 470 pound-feet of torque on offer.

This engine from Chevrolet is very rev-friendly and rev up to 6500 rpm. But the question asked is that if you should do that particularly during a cold start in the morning. The answer is that you redline your C8 Corvette but not during a cold spring as its raw oil is much thicker than warm oil and thus adds extra strain to the engine. This may also be dangerous to the car, its engine, and the people driving them. A perfect example would be the 2008-2013 models of the BMW M3, which is BMW’s performance version of the BMW 3 Series. The M3 had great powerful motorsport driven 4.0-liter V8 engine but was prone to rod bearing failure, which was mainly because of the highly wearing rod bearing material and the oil, which was too viscous and did not get warmed up properly thus causing them to fail.

But the engineers at Chevrolet were very talented and caring enough about their new 2020 Chevy C8 Corvette and have introduced a new variable redline feature with the new Corvette, thus helping its engine. This is entirely a software-based implementation and varies the redline limit in the car’s ECU (Engine Control Unit) and makes sure that the massive 4.0-liter V8 engine gets warmed up nicely before thrashing the pedal on the floor and enjoy driving the C8 Corvette. The soft rev limiter feature is not an all-new feature for the Corvette series, as it was also found on the C7 Corvette.

The soft rev limiter feature prevents the C8 Corvette’s LT2 V8 engine from spinning too fast, which is more than 3,500 rpm after a cold start in the morning. Instead, what it does is that it sets a rev limiter at 3,500 rpm and a hard cut-off at 4,500 rpm for the V8 engine. Then it waits until it gets warmer, which may differ with locations weather conditions., after which the engine can freely rev up to its actual redline at 6,500 rpm. A video on YouTube shows the user using this feature as he is driving his car. Initially, the digital screen has a red limiter at 3,500 rpm, and after some time, the graphics quickly change and now show the regular 6,400 rpm as the car’s redline.
