New AMG 6.3 Liter V8 Engine - In Detail

Press Release

Development aims and philosophy

 

Synthesis of outstanding performance and everyday practicality

 

·         The world’s most powerful naturally aspirated V8 production engine with 375 kW/510 hp

·         Effortless torque of 630 Newton metres

·         Great agility, outstanding liveliness and enormous tractive power

·         Smooth running for typical Mercedes long-distance comfort

·         Newly developed entirely by Mercedes-AMG GmbH

 

Outstanding performance and a wide usable engine speed range, a good power-to-weight ratio and sound design, a low specific fuel consumption and exhaust emission values, ease of maintenance and pedestrian protection – the requirements for newly developed engines are both varied and demanding. The same applied to the completely new AMG 6.3-litre V8 engine. The primary development goals for the engineers and product strategists at Mercedes-AMG GmbH were dynamic responsiveness, great agility, exhilarating liveliness and a high torque even at low engine speeds.

 

A glance at the key technical data shows that the aim of developing a naturally aspirated, fast-running V8 engine with a decidedly sporty character was achieved in full: the new AMG engine generates a maximum output of 375 kW/510 hp at 6800 rpm from a displacement of 6208 cubic centimetres. The new powerpack also reaches new heights where maximum torque is concerned: 630 Newton metres are on tap at 5200 rpm. This makes it the world’s most powerful naturally aspirated eight-cylinder engine, as no other unit in this output and displacement class is able to achieve these figures. A look at the torque curve also reveals its extraordinary characteristics: the new AMG V8 already delivers 500 Newton metres to the crankshaft at 2000 rpm, increasing to no less than 560 Newton metres at 3000 rpm – considerably more than the maximum values comparable engines are able to achieve at much higher engine speeds.

 

Key figures at a glance:

These remarkable figures reflect the Mercedes-AMG philosophy of building powerful engines with superlative output and torque characteristics, combined with dynamic and immediate responsiveness, which will enable drivers to use a sporty style of driving to the full.

 

With its unique, sporty AMG sound which was designed during an extensive series of tests, the eight-cylinder unit from Affalterbach offers the excitement of a naturally-aspirated, fast-running V8 engine in unmistakable audible and palpable form at low, medium and high engine speeds. Despite its pronounced sportiness, its smooth running characteristics and wide usable torque range also allow more leisurely progress when preferred – guaranteeing the long-distance comfort which is so typical of a Mercedes.

 

Completely autonomous development from Affalterbach

 

In conceptual and design terms the new eight-cylinder powerplant by Mercedes-AMG is a completely autonomous development which shares no features or common parts with other eight-cylinder engines by Mercedes-Benz. The new

6.3-litre unit differs from the other AMG V8 engines based on Mercedes designs in the distance between cylinders, the completely new crankcase concept, the sophisticated intake and exhaust manifolds and the valve train. The bore/stroke ratio is also a completely new departure for Mercedes-AMG.

 

Focusing on outstanding output and torque characteristics and decidedly sporty performance requires sophisticated technologies and solutions which are often based on motor sports engineering – which means that for mile after mile, the AMG driver benefits from more than 35 years of experience in international motor racing.
