Bentley was the only ultra-luxury marque to have a stand-alone display at the Detroit Auto Show and the British brand came strong with its upcoming Mulsanne flagship in the flesh and this special edition Continental to pique our interests. The Continental is already a stunner in its “base” trim, but not everybody is content with an “ordinary” Bentley.

The ultra-exclusive Continental adds a new Series 51 trim for 2010, named after Bentley’s first official styling department in the 1950s. Series 51 trim will be available for the entire Continental lineup and offer exclusive exterior design cues and a unique color palette. We’re talking three-tone leather with contrasting piping and stitching here, folks. Check the Series 51 box and you’ll also get 14-spoke, 20-inch wheels and a Series 51 badge on the front wings.

The new trim, which will be available throughout the Continental lineup, starts at $192,750 for the GT coupe. Click below to peruse our high resolution gallery of the Series 51 Continental GTC and hit the jump to read over the Bentley press release.

At the Geneva Motor Show in March, Bentley unveiled its fastest most powerful road car in its 90 year history in the form of the Continental Supersports. Besides significantly reducing the weight of the existing Continental GT, the Supersports marked the first step of Bentley’s move reduce its carbon dioxide emissions, in this case through the use of ethanol as a fuel for the 6.0-liter twelve-cylinder engine.

The Supersports is the first flex-fuel vehicle from the British luxury marque. At this month’s Goodwood Festival of Speed, Bentley asked repeat Le Mans winner Derek Bell to spend the weekend ferrying lucky passengers up the hillclimb course in a prototype at elevated speeds.
