2013 Aston Martin Rapide S revealed

Aston Martin has revealed the latest iteration of their four-door model, officially dubbing it the Aston Martin Rapide S. The Rapide S sedan is basically a facelift of the outgoing Rapide, but with a significant improvement in power.

The 5.9-litre V12 engine now produces 558 hp and 620 Nm of torque, an increase of 81 hp and 20 Nm. This is enough to send the Rapide S from 0-100 kph in 4.9 seconds and give it a top speed of 306 kph.

Even though the Rapide S packs more oomph, it is also more efficient than its predecessor, with reduced CO2 emissions, and with fuel economy rated at 14.1 l/100 km.

The exterior is pretty much the same, except for the significantly-larger front grille and a new rear spoiler.

The 2013 Aston Martin Rapide S is going on sale in the U.K. next month. Expect it to be released by the end of the year in the UAE, Saudi Arabia and other GCC countries.
