The CLS’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Flying Spur doesn’t offer pre-crash pretensioners.

Both the CLS 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, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, blind spot warning systems, rearview cameras, available all wheel drive, lane departure warning systems, around view monitors and rear cross-path warning.

There are over 8 times as many Mercedes dealers as there are Bentley dealers, which makes it much easier should you ever need service under the CLS’ warranty.
