As part of its 2015 performance strategy, AMG is committed to trimming down its engines that power Mercedes-Benz cars, in the pursuit of better economy and lower emissions, without compromising performance.
A raft of new technologies, including cylinder deactivation, hybrid drivetrains, direct injection and possibly turbocharged, supercharged and four cylinder engines are being considered. However, head of vehicle development at AMG, Tobias Moeres, has ruled out the demise of the V12 engine. “Some of our customers still want that level of performance,” he says.
The first engine to get the ‘small is better’ treatment is an all-new V8 bi-turbo, which will headline the S-class based AMG S63. Despite the new engine being ‘just’ 5.5-litres in capacity (down from 6.2-litres), AMG will continue with the S63 model name.
The new engine is being shown for the first time at the Geneva Motor Show today. However, what it loses in outright cubic capacity, it more than makes up for in power and torque thanks to twin turbocharging. In its basic form, the new engine develops 400kW/900Nm, yet delivers a significant economy improvement to 10.5 litres/100km, compared to the current S63’s 12.9 litres/100km.
AMG is also building a performance version of the engine that lifts outputs to 420kW/900Nm. The current S63 sedan develops 386kW/630Nm. The new V8 will appear in the S63 and CL coupe first.
