Lucky owners of BMW M3 with the sequential manual gearbox (BMW, we still haven’t gotten that test unit you sent over) are driving the first car with a built-in cheat code. The M3’s SMG transmission is electronic, preventing differential-blasting maneuvers like neutral drops (hold down the brake, rev up the car, release brake. You’ve never driven a rental car?) While better for the car, it makes showing off your new $55,000 toy a little difficult. However, switch to sport mode, put the hand shifter in drive and hold it down. Your next accelerator press will spin the engine up to 5,000 RPM (or 2,500 RPM if you have the wimpy American firmware). Let go of the shifter and the M3 will do a neck-stopping neutral drop—be ready to shift.
