[[Image:TrackTrainer.jpg|thumb|BMW Track Trainer|alt=|250x250px]] The '''BMW Track Trainer''' is a modified [[BMW 3 Series (E90)|BMW 330i]] that can negotiate a race track autonomously at the limit of traction. It was conceived as a driver training tool that allows a new student to experience the ideal race line from the driver's seat.<ref>{{Cite web|url=http://www.roadandtrack.com/auto-news/tech/bmw-track-trainer|title=BMW Track Trainer|date=8 September 2011}}</ref> The vehicle is a research project from BMW Group Research and Technology (BMW Forschung und Technik GmbH).
