Eyebrows had been raised when an Aston Martin engineer, talking on the Austrian launch of the brand new Roadster, instructed the spring and damper charges had been carried over wholesale from the coupé unaltered.
For one thing and not using a correct carbonfibre tub, this could be irregular. Once you lop the highest off a coupé, the physique usually then must be dramatically strengthened, including heft to a automobile whose axles are already not singing in excellent unison as a result of torsional stiffness has plummeted. Customized suspension charges are devised to claw again some precision and cohesion – or no less than improve the notion of these attributes.
Because it occurs, the Vantage Roadster’s rear dampers do run recalibrated software program, however the change in contrast with the coupé is minimal and the entrance axle hasn’t acquired any consideration in any respect. So is that this conversion a rush job? Budgets biting, maybe? Nope. The Roadster merely doesn’t want particular therapy, apparently.
So meagre is the burden achieve over the coupé and so stiff is the aluminium chassis (thanks partly to the very fact it was developed from the outset with each derivatives in thoughts) that from a dynamic standpoint the coupé and convertible are basically the identical. Given how eager and fun-loving the coupé is, that may be music to the ears of these in the marketplace for a rip-snorting drop-top that basically handles.
Right here’s one other shocking stat: 6.8sec. Not the 0-62mph time, fortunately. Reasonably the time taken for the ‘Z-fold’ cloth roof to arc by way of its full scope in both path. It truly is a speedy little bit of mechanical choreography. The Porsche 911 Cabriolet wants 12sec and Ferrari’s Roma Spider a bit longer nonetheless.
