Changes under the new Rapide’s skin are comprehensive, with a version of the new AM11 naturally-aspirated 6.0-litre V12 powerplant delivering unprecedented power and improved in-gear acceleration.
Power from the new engine jumps significantly versus that of its predecessor: up by 17% or a massive 81 PS from 477 PS at 6,000 rpm to a now very substantial 558 PS at 6,750 rpm.
Peak torque increases, too, up from 600 Nm to 620 Nm at 5,000 rpm. Meanwhile an even more marked improvement in torque occurs lower down the rev range, as pulling power rises by more than 40 Nm between idle and 4,000 rpm with an additional 50 Nm available at 2,500 rpm.
Naturally, increases in power and torque lead to even swifter performance as befits a four-door sports car. New Rapide S shaves 0.3 seconds off its 0-62 mph time, which drops from the 5.2 seconds of the current car to just 4.9 seconds for the new model. Top speed climbs, meanwhile, to 190 mph.
The 5,935 cc naturally aspirated V12 boasts race car technology — developments derived directly from Aston Martin Racing’s successful WEC GT campaign — to maximise both performance and efficiency. The new AM11 engine thus boasts fully CNC machined combustion chambers and lighter, hollow, cam shafts.
Dual variable camshaft timing, knock sensing, even the fully catalysed stainless steel exhaust system — these are all
engineering advances developed to preserve the V12’s position as a mainstay of the Aston Martin range.
The engine is now even more efficient, too. Despite the very significant increase in peak power and torque, the Rapide S is appreciably more economical than before. CO2 emissions drop by seven per cent — from 355 g/km to 332 g/km — while fuel economy now stands at 19.9 mpg on the official EU combined cycle.
