The fast time for the BMW (like the Porsche) was achieved using launch control. And the procedure to place the M5 into launch control is absolutely the most convoluted process our team has ever encountered. It's supposed to work like this: First, you need to place the seven-speed dual-clutch transmission in manual mode. Then, you hit the little button below the shifter joystick twice to put the transmission into the fastest shift mode. Next, you hold the traction control button down for about 10 seconds to turn all the nannies off. Then you touch the brake pedal lightly with your left foot and with your right hand push the stick forward. Next, release the brake. Finally, you simultaneously jam the throttle to the floor (making sure to really jam it, as the BMW, like the Porsche, has a stupid detent about 90 percent of the way down that you have to kick through), and release the stick. Our quarter-mile specialist Scott Mortara told me that, out of 15 attempts, he got the M5's launch control to work twice. I personally had very similar "success." Meanwhile, in the Panamera GTS, the procedure is to tap the Sport Plus button, hold the brake, floor it, and release the brake.
When will BMW realise that their over complicating things puts them at a major disadvantage in the real world...... or is it a case that they make it this complicated so as to stop people using it and save the cost of transmission repairs under warranty.
Would it not be reasonable to suggest that if any system takes this long to setup then it shouldn't be used in roadtest results.
