Bentley Mulliner has whipped the wraps of the new Bacalar, with the Crew-based luxury automaker billing the roofless grand tourer as the “ultimate expression” of two-seat, open-air opulence.

The bespoke Bentley’s name is derived from "Laguna Bacalar", a lake in Mexico’s Yucatan Peninsula. Bentley says it's the “most dynamically sculpted model to date”, with its Barchetta design language harking back to the days of classic roofless sportscars.

The Bacalar employs an uprated version of the firm’s W12 engine. In this application, the 6,0-litre twinturbo-petrol mill, which is coupled with a 48 V mild-hybrid system, produces 485 kW (up from 467 kW). The 900 N.m torque figure remains unchanged. Power is sent to all four corner’s via Bentley’s rear-biased active all-wheel-drive setup.

According to the automaker, the Bacalar (seen here dressed in Yellow Flame paintwork) shares no body panel with any other Bentley. The door handles are, however, derived from those of the Continental GT. Fresh head- and taillamps can be seen fore and aft. The doors are manufactured from carbon-fibre, while the rear clamshell is made from light-weight aluminium. Extended wheel arches, housing bespoke 22-inch alloys, and a 20 mm wider rear track (than the Continental GT) lend the Bacalar an imposing stance.

Inside, the Bacalar ditches the standard two-plus-two seating configuration for a two-seater layout. Its distinctive wraparound cockpit spans the dash, extending across the doors towards a semi-enclosed luggage compartment behind the pews.

A D-shaped steering wheel, replete with Alcantara inserts, and updated instrumentation cluster have been fitted, while the rotating centre display remains. A knurled pattern now features on the bulls-eye air-conditioning vents and myriad black and dark bronze titanium detailing can be found in the Beluga leather-wrapped cabin. Bentley says the interior features sustainable, ethically sourced materials, which were first previewed on the EXT 100 GT concept car.

Limited to just 12 units, the firm describes the Bacalar as the rarest two-door Bentley of the modern era. All examples have, of course, already been allocated to customers.
