When you sit in the driving seat of a Continental GT or Flying Spur, the dials in your field of view are a model of clarity and characterful design. It’s easy to forget that the hint of 3D knurling on the dial inners and the subtle shadowing beneath the elegant needles are all generated digitally on an active matrix Thin Film Transistor whose thickness is measured in millimeters. That’s the work of the Human Machine Interface (HMI) team, led by Graeme Smith – the specialists responsible for Bentley’s infotainment systems.
State-of-the-art technology with enduring design values
Digital technology must be integrated throughout Bentley’s interior. The ability to connect with smartphones, view 3D digital mapping, summon up the music, movies (for the passengers) and control the cabin ambiance at the touch of a finger all comes from pixels and microprocessors rather than cables and gears.
Giving those flat glass screens the same design ethos as the handcrafted wood and crisply knurled metals that surround them is a challenge, but it’s one that Graeme Smith and his team of Human Machine Interface (HMI) designers at Bentley have taken on with great success.
The skeuomorphism debate; Bentley’s philosophy
Working with the styling team in Crewe, Graeme and his team of graphic designers create a mood board of icons, colours and images that will appear in a new model. A key decision is whether to make the graphics skeuomorphic – a 3D graphic representation of a physical object – or flat digital design.
Night mode – a moment of magic
One of Bentley’s latest digital design innovations is the new dim screen mode, for those times when you don’t need any navigation or infotainment to distract you from the road ahead.
A bare minimum of information is displayed; fuel gauge and engine temperature, time, speed and outdoor temperature. Even the speedometer and rev counter dials are in darkness – except for a soft pool of light around the point of each needle.
Subtle differentiation for Flying Spur
Both the Continental GT and Flying Spur have the same driver instrumentation, but there are subtle differences in the design. Working with Bentley designers Brett Boydell and David Leary, Graeme’s team introduced a new element for the Flying Spur in the form of a bronze chapter ring around both the speedometer and the rev counter.
Where the Continental GT’s dials feature a 3D-effect to the background knurling, reflecting the design of that model’s distinctive gear lever, the Flying Spur’s dial has an outer ‘machined’ disc where the numerals sit. Both designs complement tangible design elements within the cabin; the Continental GT’s design is clearly performance-focused, while the dials of the Flying Spur convey a hint more formality.
The logistics of language
Once the design is approved, next comes the task of translating it into every menu, operation and screen. For the central display in the Flying Spur, that meant designing around 600 different icons and over 1,500 menu screens. There were the different alphabets and page orientations of English, Russian, Arabic and Chinese to incorporate, and text for 27 different languages to translate and accommodate within the screen layouts.
