In the case of RR Ghost, what is this "V-Specification"?

The V-Specification was a limited edition model sold by Rolls-Royce between January 2014-June 2014. The car came with the same 6.6 liter V12 engine but had a power boost of 30 BHP, resulting in a total of 593 BHP and 780 NM of torque. It even came with a special choice of colors from 44,000 shades in the company portfolio, but Rolls-Royce recommends 1 from 5 natural colors. Apart from the other Ghost models, the limited model got 21 inch part polished alloy wheels and came with an undisclosed price tag for those who ordered one. The standard Ghost comes with a price tag of INR 4.5 crores, making the V-Spec model more costly than ever.
