Interior is appealing with high quality materials. Smooth, powerful engine and transmission, strong/seamless acceleration from 0 to 130mph, confident handling, great soundproofing, heads up display, B&W entertainment system, comfortable seats, technology and sporty appearance are strong points. Took EU delivery and drove 2,360 miles in Germany, Switzerland, Italy and France. Great ride in all conditions' high speed German autobahn, mountain, city and country roads. Have driven 5,000 miles since returning home. Really like the intelligent cruise control, which regulates speed to maintain safe distance from Car in front. Have owned eight BMW's, including four 5 series. This is the best 5 series BMW I have owned.
I came out of the E class Mercedes Benz (owned two in the last 12 years a 2005 and 2015) both had 302 HP and fully loaded but I have to say the BMW 540i with M package offers way more performance and a more luxurious (I opted for Nappa Leather seats), comfortable and roomier cabin and is a blast to drive. I have all the options I could have had with the Benz but so much more power. The technology is state of the art and user friendly. Expect to pay mid $60k for the 6cyl twin turbo loaded package but worth every penny in my opinion.
The vehicle frequently strays out of lane even when lanes are clearly marked. When the feature is used there is added strain and stress on the driver since there is no predicting when the car will leave the lane to oncoming traffic or obstacles. The manual and videos say system can be used to over 100 mph and in traffic, and will provide a more relaxed and rested experience. DO NOT PURCHASE VEHICLE WITH THIS FEATURE because it is too dangerous to use.
