The interior is crafted with top-of-the-line materials and BMW's typical attention to detail. BMW's iDrive is intelligent and allows you to fully customize the vehicle's functions to your needs. Despite claiming to seat four, the 640i is best used as a two-passenger vehicle -- the rear seats are cramped and trunk space is limited.
Like most BMWs, the 640i is an uplifting experience on the road. The 6-Series was designed with sport enthusiasts in mind, and the 640i moves through twists and turns with power and grace. There's enough raw power to quickly get up to speed, and steering is crisp, precise and adaptable with normal and sport settings.
