Any new car, especially something like a Toyota sedan... can bounce off the rev limiter hours most likely. I don't know why people just don't throw it in nuetral. Or hell... if you're that out-of-time... throw the f-er in park. Sure it's going to probably makes expensive noises and lock up tires but who cares... especially if you are doing 120 and out of control..


Another thing that I'm thinking on ...

Just from my time in race engineering ... and calculations involving brake systems- the brakes of a modern car should be able to dissipate more energy than what is being generated by the engine. In most cases, more than twice the energy. For instance... A Formula Atlantic I worked with could accelerate at a sustained 1.1 G's. However it could brake at nearly 2.5 G's.

Even an anemic brake system is able to dissipate 2 or even 300 horsepower of heat, and it should be able to do this long enough to stop a car. I'm sure a new lexus has a relatively large brake system, and even if the engine was making peak power, jamming on the brakes should be able to pull the car down to a safe speed if not stop it, long enough to fix the problem.


The only variable here that I do not know about is ABS. I have never worked with ABS systems and how they would respond to this, maybe they would prevent the brakes from being able to kill the engine... I don't know. In my mind though it shouldn't.
