The BMW i8, by all accounts, is a pretty incredible ride. It looks sexy as hell; it's got an advanced powertrain; and the technology used on the hybrid->ke147 sports car->ke506 is arguably second-to-none. All that being said, even the i8 is entitled to a bad day or two, and as this video painfully shows, one of those bad days reared its ugly head during a recent testing session at the Nurburgring.

At the start, the i8->ke4622 looks to have been running smoothly, effortlessly stretching its legs while weaving around one of the world's most famous race tracks. But during one run down a straight, the i8 slows down and drives into a patch of grass on the side.

We don't know exactly what happened to the i8, but it doesn't look like it was part of the testing script. Maybe it lost power, or there were some mechanical glitches in that weave of wiring inside the car. But something happened to the i8 because cars like this one don't slow down on the side of the road for anything.
