2014 BMW 6-Series Overview

Is the 2014 BMW 6 Series a Good Used Car?

The 2014 6 Series is a great used car. It offers a luxurious cabin, loads of tech features, great fuel economy, and thrilling performance for a large luxury car.

Used 2014 BMW 6 Series Performance and Interior

A 315-horsepower, turbocharged six-cylinder engine powers the base BMW 640i. The 650i has a 445-horsepower twin-turbo V8, and high-performance M6 models come with a 560-horsepower version of the same V8. An automatic transmission comes standard with 640i and 650i models, while the M6 has either a dual-clutch automatic or a manual transmission. The 640i pairs the best fuel economy in the lineup (at 22 mpg in the city and 32 mpg on the highway) with plenty of punch for the typical driver. V8-powered models have significantly more power and deliver quick acceleration at any speed. The 6 Series has a smooth, stable ride and feels planted around turns, but it isn't as athletic as some rivals are. Think of it as more of a grand-touring car. An adaptive suspension and rear-wheel drive are standard, while all-wheel drive (called xDrive) and rear-wheel steering are available.

The 6 Series' cabin has first-rate materials and a driver-focused design. Coupe and convertible 6 Series models have seats for four, while Gran Coupe models can accommodate five people. Leather seats, heated front seats, and power-adjustable front seats are standard in all trims. The standard front seats are very comfortable, while the available multicontour seats provide enough adjustments to suit any body type. The rear seats are not roomy compared to those in rivals, though the Gran Coupe's back seats are the most accommodating of all the body styles, owing to the rear doors.

The base 640i comes standard with a 10.2-inch iDrive infotainment system, navigation, HD Radio, satellite radio, Bluetooth, and a USB port. Some models add a Harman Kardon or Bang & Olufsen audio system. With crisp graphics, straightforward menus, and quick responses, the iDrive system is intuitive to use. A head-up display is also available, and it projects driving information (including navigation directions and your current speed) directly onto the windshield in front of the driver. Gran Coupe models have 16.2 cubic feet of trunk room, which is above average for the class. Convertible and coupe models have less available cargo space.

Should I Consider Another Used 6 Series?

The 2014 6 Series is part of the car's third generation, which launched for the 2012 model year and includes the 2018 6 Series. For the 2014 model year, BMW updated the iDrive infotainment system, launched the M6 Gran Coupe trim, made a manual transmission available in M6 models, and made all-wheel drive available in the base 640i trim. BMW introduced the Alpina B6 trim for 2015 and added more power to that trim for 2016. Unless you want the Alpina B6 model, save some money and stick with the 2014 6 Series.

Which Used BMW 6 Series Is Right for Me?

If you need room for adults in the rear seats, you'll want a Gran Coupe model, which has four doors. Otherwise, you can also consider the coupe and convertible body styles. Rather than offer different features in different trim levels, the only notable difference between models is the engine. Most drivers should be satisfied with the 640i's six-cylinder, but those who desire quicker acceleration may find the 650i's V8 more to their liking. If you live in areas with inclement weather, consider a model equipped with xDrive.

You might also want to consider a certified pre-owned 6 Series. The BMW CPO program has three levels based on the vehicle’s age and the number of miles on the odometer: Certified Pre-Owned Elite, Certified Pre-Owned, and Pre-Owned. Each level receives the balance of the original new-car warranty. Certified Pre-Owned Elite vehicles get an additional one-year/25,000-mile warranty, while Certified Pre-Owned models receive an additional two-year/50,000-mile warranty. Pre-Owned BMWs receive no additional coverage. Each BMW undergoes an inspection before earning CPO status. Additional benefits like towing and roadside assistance may be available, so read the BMW warranty page carefully.

2014 BMW 6 Series and Other Cars to Consider

Which Is Better: 2014 BMW 6 Series or 2014 Audi A7?

Overall, the Audi A7 is a better car than the 6 Series. It has sporty handling and powerful engines like the 6 Series, and it's cabin is luxurious and comfortable. The A7 gets a class-leading reliability rating that helps it rank near the top of the class, and thanks to the A7's hatchback body style, there's exceptional cargo room available.

Which Is Better: 2014 BMW 6 Series or 2014 Mercedes-Benz E-Class?

Though the Mercedes-Benz E-Class is part of our luxury midsize class and not the 6 Series' luxury large car class, it has more back-seat passenger room than the BMW. The E-Class also has better reliability ratings and fuel economy estimates. This is on top of having poised handling, punchy engines, and an opulent interior like the 6 Series.
