Amazing performance, terrible fuel economy

The performance, ride, comfort and amenities are all amazing. The car is fun to drive and fun to just sit in. There is a price to pay, though. Having all that power and torque on tap makes it too tempting to drive the car aggressively. But when you do, you'll get nowhere near the car's rated mpg estimate. I've only had mine a few weeks now and I'm getting around 15 mpg. Maybe that will improve once the initial thrill has worn off, maybe not.

Guys , this 640i grand coupe fully loaded is a stunner on the road and sitting in my garage. Some guy in a Lexus GS wanted to play on the highway last weekend. I hit sport mode and sliced and him so bad, he will never forget he tried to get cute with the grande coupe. My wife could not understand what came over me. I told her its a guy thing. The grand coupe can park next to anything in the swanky part of town and look stunning. You get Comfort , luxury. Fuel Efficiency and sexy as a runway model. Don't let the online pictures fool you go have a look for your self. Kingc0mm

One bad BMW experience does not define a brand! I absolutely love this car. I've been driving BMWs for over 20 years and this is by far the best car I've ever driven. Performance, comfort, and high quality. The look and lines of the car are almost sensual..

Buyer Beware of BMW

- Infotainment System went out frequently while driving - SOS button malfunctioning frequently - Entire dash going out and coming back on while driving Trunk randomly opening when parked or before driving off (if you are fast enough to get in and lock doors, etc., it won't open. BMW was made aware of the problems but refused to do a Trade Assist Program on this faulty vehicle because of high mileage (29,000), amount still owed (only 12 months of payments) and repair attention not an emergency. Wife had same vehicle (except coupe) we bought one day apart, and they took it back (only constant brake problems and water leaks in the trunk (at 15,000 miles). I recommend steering clear of BMW, but if you still insist, stay away from 2014 640i Xdrive Gran Coupe.

I bought my 2014 640i x-drive in 2017 with 19,000 miles on it. I love its look and style. It gets its share of oohs and awhs. It gets good fuel economy, but I seldom drive it very hard. Unfortunately, I had to replace the head gaskit after only 58,000 miles. It rides pretty well for having low profile run-flat tires. Bottom line is that "I love this car!"

I really enjoy driving this car as it's quick, stylish and beautiful with both interior and exterior quality above most on the road. Keep in mind that this is big vehicle so quick is a relative, but in true BMW fashion the car will get you up to 80mph+ without you even being aware even in city traffic. However, there is a noticeable lag from the turbo and gas mileage borders on atrocious for this day and age when driven even just modestly aggressive. With that said, it's quiet and smooth at speeds of even 100mph. The I-Drive is far better than the old days and better than any I've used. Also, the rear seats fold down which increases the utility greatly and was one of the reason I decided to buy this model. The interior quality is among the best, although taller drivers and passengers will need to watch their heads as the car is low and wide both inside and out.So you get a gorgeous car, room for large items in the back (especially with the rear seats folded) as well as a wonderful touring car with front seats that will make your time in the car very comfy. All this for a mere $90K or so.... And that's where the rub is for me. Despite being treated with the M badging and upgraded package, my in line 6 cylinder still lacks fairly basic items like blind spot detection, intuitive cruise control, lane keep, upgraded stereo and the one that drives me crazy, a power trunk. The power trunk is not even an option, but adding these other items along with the accompanying, required packages and you're approaching $100K. In addition, I had to pay extra via aftermarket hack to have simple things like mirrors fold with remote, windows down with remote, auto engine shutoff disabled. Seems to me that even for the messily $87K that my car cost new it should really have these items. I am pretty sure the same year Honda Accord has more amenities. I mean, come on BMW. In short, love the way the car looks and drives, miss the gadgets, hate the value for price proposition.

Great shopping experience. Mileage was super low. Edmund's has very accurate information and made it easy to connect with the dealer.
