Two million pounds. That’s how much each Batur Convertible is expected to cost, once customers have personalised their limited-edition car to their exacting tastes. I assure you, dear reader, that isn’t a typo. The Batur is Bentley’s final convertible application for the venerable 6.0-litre twin-turbo W12 engine before production ends this summer and it certainly looks like an impressive setting to close this particular chapter of Bentley’s engine history, but does it look like it’s worth £2 million?

At first glance, I’m not so sure. The Batur is a model made by Bentley’s in-house Mulliner coachbuilding division. The name has been applied to an extensive customisation programme for years but more recently the name returned to its coachbuilding roots by creating ultra-exclusive models based on the Bentley Continental GT. It started with the roofless Bacalar in 2022 which was followed by the Batur coupe of 2023. Both preceding models cost over £1 million and while it was clear to see why with the Bacalar, I struggled to see it with the Batur.

Styling-wise, it’s clear what car this is based on; everything from the shape and placement of the grille, front bumper inserts, high-level character line and blistered rear wheel arches look - to the untrained eye at least - like the Continental GTC. That’s not an insult, but the Continental GTC starts at around £200,000, or 10% of the cost of the Batur.

It is said that the Batur previews the styling of future Bentley models so we’d better get used to the tall and wide square-shaped grille, two headlights as opposed to four, and a more tapered rear end than we have yet to see on production Bentleys. Speaking of the rear end, there’s no confusing its origin here; the narrow light clusters draw inspiration from those at the front but now feature three individual LEDs that get wider towards the centre.

Rather than an overly fussy diffuser design, the rear bumper features just one downwards strake in the centre, with clean bodywork extending away from it in both directions. Two large trapezoid exhaust outlets are mounted at the outer edges. The highlight for me is the integrated ducktail spoiler which takes a design trick usually used for bonnets and applies it to the boot lid; a line on either side of the car raises up and creates an elevated section for the ducktail spoiler to emerge from. Think of it as a power dome for the boot lid - I like it a lot, even if I don’t think the rear-end design matches up perfectly with the front end.

Could it be that the true differentiators lay within? Well…not really. Again, at first glance, the cabin of the Batur Convertible still looks rather familiar. The interior looks like a wonderful place to be with the mixture of wood, leather and intricate metal trim. The three-piece rotating dashboard can show the infotainment system, three analogue dials or a continuation of the interior trim at the touch of a button - it’s still one of the coolest interior items I’ve ever seen and flies in the face of the race to fit ever larger screens inside passenger cars.

Indeed, Bentley also gives a Great British two-fingered salute to the removal of physical buttons for car controls; by the looks of it there is no need to sift through multiple infotainment menus to adjust things like the air conditioning, heated seats, driving mode or to operate the fabric soft top which takes just 19 seconds to fully open or close and can be done at speeds of up to 30 mph. Strangely, the Batur Convertible is a strict two-seater and although it looks large enough to offer seating for four, this isn’t the case.

The designers opted to give the car a wraparound cockpit - closer to a two-seater like a Porsche Boxster -and this is something that I’m onboard with. I much prefer two-seat convertible cabins over more open four-seat interiors - I’d put that down to spending so much of my life in SLKs.

This effect has been achieved with a cowling that covers the rear of the cabin and there is a rather lovely trim element called the “airbridge” that sits above it. The area below the cowling can be used as an extra storage space and no doubt, there will be specially made luggage available. The thing is, unlike with the roofless Bacalar, the covered rear section on this four-seater(based) convertible just doesn’t look quite right to my eyes - have a look at the Aero Cowling for the Rolls Royce Dawn and you’ll see what I mean.
