Which isn’t to suggest that it generates no satisfaction; immersed in the GT’s heavy-duty attitude to everything - not least its brooding, caddish image - it’s possible to enjoy it thoroughly.
Alternatively, the Speed can be made to go offensively fast. Credit where it’s due, Bentley manages to make 626bhp – more than you’d find in a Ferrari 458 Scuderia – seem like an utterly usable commodity. Swift progress is as easy as embezzlement and very nearly as detached.
Kept in its Sport mode (accessed via the gearbox in the same way as any other Volkswagen) the Speed tools up high streets and thunders down carriageway as though it were warming up for an invasion; and, like a war reporter embedded with a cavalry brigade, it’s hard not to get swept up in the throbbing energy of it all.
Nevertheless, the handling limits are obvious enough if you start trying too hard. Canter forcefully into bends or a roundabout with the kind of abandon you’d apply to a middling hot hatch and the GT loses its mind, its amenable suspension being no match for the concrete church organ of cylinders and pistons located up front.
Such is the weight penalty that tweaking the adaptive dampers to their firmest setting won’t do much other than introduce a secondary niggle to a ride quality already forced to manage well beyond two tonnes while wearing 21in alloys.
Should I buy one?
It’s quite possible that your average Speed buyer would no more fiddle with the suspension button than drink Tesco’s own-brand Cava – or expect any more handling finesse than is required to sweep you blithely around motorway bends.
But the fact that Bentley builds a manifestly superior version of the GT is hard to ignore from an enthusiast point of view. The much-praised V8 S may have 118lb ft less on paper, but it too is extravagantly fast and is better wired for fun when the mood takes you.
The notion of the more agile, cheaper, less thirsty and substantially more efficient GT being the finer example of the breed may be counter-intuitive to those buying on the steadfast belief that size matters, but the latest iteration of the W12 does nothing to countermand the idea that the Bentley is best with four fewer cylinders.
Crewe’s continued investment in the engine suggests it feels the current Speed has a decent amount of life left in it yet, although it will be a naïve UK buyer who signs up for the experience without a pronounced affinity for its increasingly anachronistic appeal.
