What happens if i redline my car

Well, the movies would have us believe that riding the redline in a vehicle will squeeze out every drop of oomph but by revving your car to redline or, worse, holding it on the redline, all you really do is cause the engine to tear itself apart. See, car makers determine the redline of an engine based on several things like peak power and torque delivery but also on the structural strength of the componentry, including the piston, bearings, valves and so on.

And these things tend to prevent you from either revving to redline or holding the car on the redline — but rev limiters are a reasonably modern thing. What the rev limiter does to prevent over-revving is to cut fuel flow to the engine or it might also fiddle with the ignition system but, in both instances the system aims to reduce revs to a safer level.

In a sportier vehicle, the transmission will be allowed to rev closer to redline or even hit it briefly usually only in Sports mode. And, in vehicles with a manual override function, like the Kia Stinger, the transmission will be allowed to hit the redline before upshifting…but they will upshift.

Beyond those peak rpms, power and torque starts to drop away, so, revving beyond the rpm peak power output is theoretically pointless. Driving Tips. Maintenance Tips. Car Review. Car Comparison.

However, a vehicle that is driven on very short trips and that rarely gets up to proper operating temperatures can still suffer from carbon buildup issues. Redlining might be an effective way for certain vehicles to keep engines running clean. Photo courtesy of Flickr. Know How. Having been bitten by the car bug at a young age, I spent my formative years surrounded by Studebakers at car shows across Quebec and the northeastern United States.

Over ten years of racing, restoring, and obsessing over automobiles lead me to balance science writing and automotive journalism full time.
