MERCEDES-AMG’s Frankfurt stage looks set to be chock full of hot hardware this year with an updated S63 and S65 Coupe and Cabriolet now confirmed to debut alongside the growing line-up of Affalterbach-fettled machines on show.

Both V8 and V12 versions of the Coupe and Convertible will be competing for attention, but the smaller-engined S63 has the most to shout about with a version of AMG’s hand-built twin-turbo V8 that takes combined power and torque output to a level not yet seen from the unit.

With 450kW and 900Nm under their bonnets, the S63 Coupe (above) and Convertible (below) match the previous 4.0-litre V8 power hero, the E63S, but with another 50Nm squeezed out.

Despite having an extra four cylinders and 2.0 litres of displacement at their disposal, the updated AMG S65 Coupe and Cabriolet produce just 13kW and 100Nm more than the new V8, highlighting the achievement of AMG’s latest engine compared with the ageing 6.0-litre twin turbo V12, which carries over unchanged with the update.

There’s more preferential treatment for the S63 when it comes to the transmission, which has been upgraded to the company’s nine-speed Speedshift MCT auto, while the S65 continues on with its seven-speed version.

A new-design alloy wheel complements the styling refresh with a 19-inch version for the S63 and larger 20-inch items for the V12 version.

The update comes just two years after the S-Class Cabriolet was revealed at the Frankfurt show, while the Coupe version has been doing the rounds since it debuted in March 2014 in New York.
