2020 Bentley Mulsanne Speed Safety and Reliability

Local authorities haven't gone through the arduous task of destroying a $300,000 luxury car, so no official safety ratings exist for the Mulsanne Speed. In the event of an accident, though, there are likely many worse places to be than inside the massive Mulsanne.

The Mulsanne Speed may be a luxury and craftsmanship benchmark, but it's rather off the pace in terms of standard safety gear. You do, of course, get essentials like eight airbags (including side curtain airbags), front and rear parking sensors, a rearview camera, automatic stability control, a hill holder function, tire pressure monitoring, and daytime running lights.

It's in the area of modern driver-assist technologies that the Mulsanne Speed falls short: adaptive cruise control and a corner-view camera are both optional extras, while lane keeping assist/lane departure warning aren't available at all. Blind spot monitoring and forward-collision warning are standard, however.

The Mulsanne Speed has been free of recalls over the last two years, but there were two issues for the 2018 model year. One was for an obstructed/delayed rearview camera, and another was for a rear seat belt buckle that could detach, increasing the risk of an injury in the event of an accident.

Bentley's warranty runs for only three years (including the powertrain) but there is no limitation on miles covered within this period.
