Its bodywork was shared with no series Bentley beyond the door handles. Factory specification, luggage and service history define each car. 2020 to 2021 · 12 built · Crewe ## The price and the proof Indicative road-car band $850K–$1.3M · 1 documented road sales · 1 recorded sales on file. Modeled values are not observed sales. Nothing here is investment advice. Confidence: low. The band rests on one exact-model public result: Bacalar number five, a 1'131-kilometre first-owner car, sold by RM Sotheby's in December 2025. Twelve individually specified cars are too few for a stable average, and colour, equipment, factory documentation and taxes make headline comparisons coarse. Figures in USD. The sole documented public sale entered the UAE on a temporary import bond; local duties were excluded from the auction result.

Private Bacalar transactions remain undisclosed. ## Mulliner reopened the coachbuilding book Bentley revealed the Bacalar at Crewe on 3 March 2020. All twelve cars were already allocated, and customers worked directly with Mulliner on paint, leather, textile, veneer and detail finishes. Customer production began in 2021. By August 2022 eight cars had been delivered and the final four were in preparation, closing a run in which each car took about six months to complete. The programme led directly to the Batur. | Highlight | Detail | | --- | --- | | A roof was never engineered | The Bacalar is not a Continental convertible with its hood hidden. There is no roof provision, two rear cowls sit behind the seats, and bespoke Schedoni luggage occupies the semi-enclosed compartment behind them. | | One shared exterior part | The door handle is the only exterior component shared with a Continental GT, retained because it carries the keyless-entry hardware. Carbon-fibre doors and wings meet an aluminium rear clamshell and top deck. | | Material choices became structure | Rice-husk-ash pigment, natural British wool and 5'000-year-old Riverwood moved from the EXP 100 GT concept into a customer car. They were not a trim package: every owner worked through a separate material specification. | | Label | Value | | --- | --- | | Power | 659 PS | | Built | 12 | | Seats | 2 | | Design | Stefan Sielaff | | Allocation | Fully allocated | ## Technical specifications ### Powertrain and chassis | Label | Value | Note | | --- | --- | --- | | Engine | 6.0-litre twin-turbo W12 TSI | factory specification | | Power | 659 PS | 650 bhp · factory figure | | Torque | 900 Nm | 667 lb-ft · factory figure | | Gearbox | 8-speed dual-clutch | | | Drive | Active all-wheel drive | rear-wheel drive used where conditions allow | | Chassis control | 48-volt Bentley Dynamic Ride | adaptive air suspension and active anti-roll control | ### Body and materials | Label | Value | Note | | --- | --- | --- | | Configuration | Two-seat roofless barchetta | no folding or removable roof supplied | | Shared exterior parts | Door handle only | shared with the Continental GT for its keyless-entry hardware | | Doors and wings | Carbon fibre | | | Rear clamshell and top deck | Aluminium | | | Rear track | +20 mm | versus Continental GT | | Wheels | 22-inch tri-finish | | ## The people behind the car ### [Stefan Sielaff](https://hiconium.dev/people/stefan-sielaff) Director of Design · Bentley Led the Bentley design team that transferred the EXP 100 GT's horizontal lighting, wraparound cockpit and material programme into the roofless Bacalar. ## Member instruments A HICON Bid is a confidential expression of buying interest on this file.
