 | Illustrated: BMW SMG II Shifter |
Gearbox - SMG II - Hidden Feature: There's a cheat code in the software running the BMW M3's sequential manual gearbox (SMG): Press the right buttons in the right order and the car will launch you from a stop after revving the engine to 3,800 (European Software) rpm. But don't look for a how-to in the owners manual, this feature is undocumented.
| It's also the first automotive "Easter egg," though, with increased reliance on computers, it would seem just a matter of time before they become standard fare, much like the hidden features in PC games and DVD movies. In the M3's case, there's also good reason for it: The SMG transmission is completely electronic, so you can't rev the engine and drop the clutch for tire-smoking acceleration, something the owner of a performance sedan just might want to do occasionally.
But there is a catch. If this feature is used too frequently, the gearbox warning light will start flashing and the revs will be restricted to 2000 rpm, until the engine is restarted. In Europe, where the feature isn't so hush-hush, doing more than 15 launches voids the car's warranty. U.S.-spec cars are programmed to wind to only 1,800 rpm, however upon request the European software will be installed by your BMW Dealer.
For lucky drivers of this hot car, here's how: Switch off the stability system and select shift program six. Switch the engine to sport mode. With the hand shifter in drive, hold it in the downshift position and press the accelerator. The engine will rev to the preprogrammed rpm and hold. Now release the shifter. The car will launch forward violently and the engine's revs will climb quickly, so be prepared to upshift, and your head pushed against the headrest. | | :: Recommended Reading / Videos :: | | | |
