The Electrified G80 has been driven. Korea-based automotive YouTuber Asian Petrolhead has posted a video with him driving the car and sharing his thoughts. Overall, he seems pretty impressed. About 12 minutes in, my accelerates a bit in a turn and you can see the back end step out a bit. This would indicate a strong bias toward the rear motor. He also said it was very easy to catch, so it seems like it should be a nice combination of good chassis engineering with good stability software.
