Compare the2025 BMW M8VS 2025 Bentley Flying Spur

The M8’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 Flying Spur doesn’t offer a driver alert monitor.

Both the M8 and the Flying Spur have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The M8 comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Flying Spur’s 3-year basic warranty expires 1 year sooner.

The M8’s corrosion warranty is 9 years longer than the Flying Spur’s (12 vs. 3 years).

BMW pays for scheduled maintenance on the M8 for 3 years and 36,000 miles. BMW will pay for oil changes, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Bentley doesn’t pay scheduled maintenance for the Flying Spur.

There are over 7 times as many BMW dealers as there are Bentley dealers, which makes it much easier should you ever need service under the M8’s warranty.

The M8 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 Flying Spur doesn’t offer ceramic brake rotors.

The M8 stops much shorter than the Flying Spur:

The M8 Gran Coupe handles at 1.02 G’s, while the Flying Spur pulls only .94 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the M8 Competition Coupe’s turning circle is .7 feet tighter than the Flying Spur’s (40 feet vs. 40.7 feet).

The BMW M8 may be more efficient, handle and accelerate better because it weighs about 1250 to 1550 pounds less than the Bentley Flying Spur.

The M8 Gran Coupe is 1 foot, 5.5 inches shorter than the Flying Spur, making the M8 easier to handle, maneuver and park in tight spaces.

The M8 Gran Coupe has a much larger trunk than the Flying Spur (15.5 vs. 12.2 cubic feet).

The M8’s standard rear seats fold to accommodate long and bulky cargo. The Flying Spur doesn’t offer folding rear seats, only a ski pass-through.

If the windows are left open on the M8 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Flying Spur can’t use the remote to operate the windows.

The M8’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Flying Spur’s cruise control switches are unlit, making them difficult to find at night and operate safely.

Laser headlights, standard on the M8, produce their light by firing blue lasers through phosphorus, a process that uses one-half the power of the Flying Spur’s LED headlights. Laser headlights can have double the range of LEDs with a much smaller surface area.

The BMW M8 has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Bentley charges extra for Homelink® on the Flying Spur.

The BMW M8 comes in coupe, convertible and sedan bodystyles; the Bentley Flying Spur isn’t available as a coupe or convertible.

The BMW 8 Series outsold the Bentley Continental/Flying Spur by over two to one during 2023.
