Earlier this month we brought you news that Bentley is working on a more powerful version of its Mulsanne flagship sedan. We now have a report claiming the more powerful Mulsanne will carry the Speed title currently applied to the most powerful versions of Bentley’s Continental GT and Flying Spur models.

Auto Express, citing Bentley insiders, reports that a new Mulsanne Speed is coming, and that it will be rated at around 550 horsepower, up from the standard Mulsanne’s 505 hp. By comparison, the 2015 Continental GT Speed is rated at 626 hp.

You might be wondering why Bentley’s Mulsanne Speed won’t be the most powerful weapon in the British automaker’s arsenal. It’s because the big sedan will be sticking with the standard Mulsanne’s twin-turbocharged 6.75-liter V-8 instead of adopting Bentley’s more potent W-12. To further boost performance, however, the Mulsanne Speed is likely to benefit from some weight-saving measures and chassis tweaks.

Combined, all of the modifications should see the Mulsanne’s 0-60 mph time drop under 5.0 seconds for the first time and its top increase from the current 184 mph figure.

The new Mulsanne Speed is expected to make its debut later this year, most likely at the 2014 Paris Auto Show in October. Sales should commence shortly after the car’s reveal, with pricing likely to lie well north of the standard Mulsanne’s current starting price of just under $300k.
