Bentley’s updated 2021 Flying Spur has gained increased technology with the posh British brand claiming to have "eliminated" noise, vibration and harshness.

The luxury four-door sedan has gained a raft of new standard equipment alongside the refinement-boosting tweaks, as well as an enhanced array of personalisation options, just a year after its launch.

Bentley used 'virtual prototyping' processes to carry out acoustic tests on all parts of the car, identifying areas that produced "unwanted cabin noise". Following the tests, some 40 different components of the car were lightened to make way for additional soundproofing.

Bentley used virtual prototypes prior to carrying out the modifications, so was able to minimise its testing mileage and reduce the number of physical prototype cars in operation.

Elsewhere, the Flying Spur is now equipped with the City Specification package as standard, which brings traffic-sign recognition, hands-free boot opening, a top-down parking camera, welcoming lighting and automatically dimming mirrors. 

A new cabin ioniser emits negatively charged particles through the air-conditioning vents, which create a static charge around airborne particles, causing them to stick to the nearest surface rather than float around the interior.

"The result is to remove such contaminants from the air that the occupants breathe, thus improving the feeling of wellness,” says Bentley.

A new exterior paint colour, Cambrian Grey, is available for 2021, as are a range of 'open-pore' wood veneers for the interior. 

The Flying Spur remains available with a choice of V8 or W12 petrol engines. Prices start from $395,000.
