Safety

The 6 Series Gran Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Charger SRT doesn’t offer pre-crash pretensioners.

The 6 Series Gran Coupe has standard Post-Crash Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Charger SRT doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The 6 Series Gran Coupe offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Charger SRT doesn’t offer all-wheel drive.

A passive infrared night vision system optional on the 6 Series Gran Coupe helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Charger SRT doesn’t offer a night vision system.

The 6 Series Gran Coupe offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Charger SRT only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

The 6 Series Gran Coupe’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Charger SRT doesn’t offer a driver alert monitor.

Both the 6 Series Gran Coupe and the Charger SRT have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems and blind spot warning systems.

Warranty

The 6 Series Gran Coupe comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Charger SRT’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

The 6 Series Gran Coupe’s corrosion warranty is 7 years and unlimited miles longer than the Charger SRT’s (12/unlimited vs. 5/60,000).

BMW pays for scheduled maintenance on the 6 Series Gran Coupe for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Dodge doesn’t pay scheduled maintenance for the Charger SRT.

Reliability

For smoother operation, better efficiency and fewer moving parts, the engines in the 6 Series Gran Coupe have an overhead cam design, rather than the old pushrod design of the engines in the Charger SRT.

To reliably start during all conditions and help handle large electrical loads, the 6 Series Gran Coupe has a standard 900-amp battery. The Charger SRT’s 730-amp battery isn’t as powerful.

J.D. Power and Associates’ 2017 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Dodge vehicles. J.D. Power ranks BMW 6th in initial quality, above the industry average. With 18 more problems per 100 vehicles, Dodge is ranked 22nd, below the industry average.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Dodge vehicles. J.D. Power ranks BMW 8th in reliability, above the industry average. With 39 more problems per 100 vehicles, Dodge is ranked 23rd.

From surveys of all its subscribers, Consumer Reports’ April 2018 Auto Issue reports that BMW vehicles are more reliable than Dodge vehicles. Consumer Reports ranks BMW 19 places higher in reliability than Dodge.

Regenerative brakes improve the 6 Series Gran Coupe’s fuel efficiency by converting inertia back into energy instead of wasting it. The Charger SRT doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the 6 Series Gran Coupe’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Charger SRT doesn’t offer an automatic engine start/stop system.

The 6 Series Gran Coupe M6’s standard fuel tank has 2.6 gallons more fuel capacity than the Charger SRT (21.1 vs. 18.5 gallons).

Transmission

The 6 Series Gran Coupe offers a manual transmission for better acceleration, control and fuel economy. The Charger SRT doesn’t offer a manual transmission.

The 6 Series Gran Coupe offers an available sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Charger SRT doesn’t offer an SMG.

Brakes and Stopping

For better stopping power the M6 w/Carbon Brakes’ front brake rotors are larger than those on the Charger SRT:

Charger SRT

Front Rotors

16.1 inches

15.4 inches

Rear Rotors

13.8 inches

The 6 Series Gran Coupe M6 offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Charger SRT doesn’t offer ceramic brake rotors.

The 6 Series Gran Coupe stops shorter than the Charger SRT:

Tires and Wheels

The 6 Series Gran Coupe’s optional 245/35R20 front and 275/30R20 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the Charger SRT’s 40 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 6 Series Gran Coupe can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Charger SRT doesn’t offer run-flat tires.

Suspension and Handling

The 6 Series Gran Coupe offers an available active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Dodge doesn’t offer an active suspension on the Charger SRT.

For better handling and stability, the average track (width between the wheels) on the 6 Series Gran Coupe is 1.3 inches wider in the rear than the track on the Charger SRT.

The 6 Series Gran Coupe’s front to rear weight distribution is more even (50.1% to 49.9%) than the Charger SRT’s (55% to 45%). This gives the 6 Series Gran Coupe more stable handling and braking.

The M6 Gran Coupe handles at .95 G’s, while the Charger SRT Hellcat pulls only .90 G’s of cornering force in a Road and Track skidpad test.

Chassis

The BMW 6 Series Gran Coupe may be more efficient, handle and accelerate better because it weighs up to about 250 pounds less than the Dodge Charger SRT.

The 6 Series Gran Coupe is 3.6 inches shorter than the Charger SRT, making the 6 Series Gran Coupe easier to handle, maneuver and park in tight spaces.

Passenger Space

The 6 Series Gran Coupe has 2 inches more front headroom, .3 inches more front legroom, 3.5 inches more front hip room, .4 inches more rear headroom and 1.1 inches more rear hip room than the Charger SRT.

Cargo Capacity

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the 6 Series offers cargo security. The Charger SRT’s non-lockable folding seat and non-lockable remote release defeat cargo security.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that BMW service is better than Dodge. J.D. Power ranks BMW 8th in service department satisfaction (above the industry average). With a 76% lower rating, Dodge is ranked 30th.

Ergonomics

Unlike the driver-only memory system in the Charger SRT, the 6 Series Gran Coupe offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The 6 Series Gran Coupe offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Charger SRT doesn’t offer a heads-up display.

The 6 Series Gran Coupe’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Charger SRT’s rear power window switches have to be held the entire time to open or close them fully.

The 6 Series Gran Coupe’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Charger SRT’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The 6 Series Gran Coupe has standard headlight washers to keep headlight output high. The Charger SRT doesn’t offer headlight washers.

To help drivers see further while navigating curves, the 6 Series Gran Coupe has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Charger SRT doesn’t offer cornering lights.

A power rear sunshade is optional in the 6 Series Gran Coupe to help block heat and glare for the rear passengers. The Charger SRT doesn’t offer a rear sunshade.

The 6 Series Gran Coupe (except xDrive)’s optional Parking Assistant can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Charger SRT doesn’t offer an automated parking system.

Model Availability

The BMW 6 Series comes in convertible, sedan and four-door hatchback bodystyles; the Dodge Charger SRT isn’t available as a convertible or four-door hatchback.

Economic Advantages

Insurance will cost less for the 6 Series Gran Coupe owner. The Complete Car Cost Guide estimates that insurance for the 6 Series Gran Coupe will cost $1055 to $7360 less than the Charger SRT over a five-year period.
