As any drag racer will tell you, achieving the perfect launch is something of an art form. Or maybe it’s closer to areligion to the people constantly struggling to find exactly the right RPM, clutch technique & number of prayers to the God of the Quarter Mile.Naturally, having a computer take all the guesswork out of the process (cheating? Not if everyone else is doing it… & they are) makes everything more than a little bit easier. The Lexus LFA is the latest supercar to get the technology here in the States. But how does it work?Glad you asked. Lexus’ carbon fiber wonder-mobile is finally hitting the streets, & its h&y-d&y owner’s manual outlines the launch controll process rather nicely. Nicely, but not exactly easily… as you might expect from a factory-installed technology that is known to be rather stressful on drivetrain components. See what we mean after the break.
