The £220,000 Bentley Mulsanne will be in production by next spring at the company's Crewe HQ, with first deliveries scheduled for the summer.
The 6.75-litre, V8-engined supercar, which has already starred at motor shows in Pebble Beach and Frankfurt, is primarily targeted at rich and discerning Americans.
With a choice of 114 body and 21 carpet colours, nine wood veneers and 24 styles a of leather interior, each of the fuel and CO2-efficient cars will take nine weeks to build.
Says spokesman Stuart McCullough: "Even at this very early stage, the expressions of interest we've received easily exceeds our 2010 production targets.
"Mulsanne's credentials are a pure expression of Bentley design and craftsmanship, and that's struck a chord with Bentley enthusiasts across the globe, as well as many of the potential customers we have welcomed for tours in Crewe this year.
"We've been encouraged by the positive commentary, notably from our American customers as the Mulsanne was privately previewed in seven metro markets across the country."
