This car isn´t realy build for perfromance..
car and driver tracktest sumary
Infiniti G37 didn’t feel terribly comfortable on the track and required plenty of cooling time between hot laps. Fingers point to its 3723-pound weight (which led to brake fade after only a few big stops), an engine that didn’t quite feel like 330 horses, and easily overheated and thus slippery tires. Pound the brakes hard, and the G37 assumes a crash is imminent and cinches up the seatbelts—as if we needed more evidence that this car was not suited to track workouts.
Not realy a BMW competition..
