Mercedes approves new straight-six engine

Straight-six engines are a BMW hallmark, but their rivals in Stuttgart could be preparing to adopt the acclaimed engine configuration.

 

Citing a "friendly Mercedes engineer," CAR is reporting the company has approved a new engine family that will be launched in 2015. Details are limited, but the source said there will be a variety of new four-cylinders, inline-sixes (available in both single and twin-turbo guise) and downsized V8s displacing 4.0-liters.

Mercedes Benz have been using straight six engines up till 1995. It was only in 1996 that they adopted the V6. So it is more like a return to the straight six for them after a 20 year hiatus.

Mercedes never wanted to return the S-6 route since adopting V6 configuration....but after BMW started using S-6 lesser on their models..Mercedes decided to backtracked their decision.

What is the difference between inline 6 and V6? Does inline6 provide more raw power?

 

In line 6 is better balanced...hence smoother especially top end...but need a much longer bonnet..

 

V6 is more compact in size...but not as smooth and well balanced....so not as smooth as inline 6 especially at high rev...

The straight-six engine or inline-six engine (often abbreviated I6) is a six cylinder internal combustion engine with all six cylinders mounted in a straight line along the crankcase. The single bank of cylinders may be oriented in either a vertical or an inclined plane with all the pistons driving a common crankshaft; in vehicles where this engine is installed inclined versus vertical, it is sometimes called a slant-six engine. The straight-six layout is the simplest engine layout that possesses both primary and secondary mechanical engine balance, resulting in relatively low manufacturing cost combined with much less vibration than engines with fewer cylinders.[1]

 

this is straight 5 [cool]

The straight-five engine or inline-five engine is an internal combustion engine with five cylinders aligned in one row or plane, sharing a single engine block and crankcase. This configuration is a compromise between the smaller inline-four engine and the larger straight-6.

 

Historically, straight-five engines have been used rarely but continuously since their invention, though they have become increasingly popular in recent years. They are used in Audis, Fords, Volkswagens, Volvos, Land Rover TD5s and on some diesel-powered Mercedes-Benz models, as well as on the Acura 2.5 TL and Vigor. Recently, General Motors launched a straight-five engine for its popular compact trucks (Chevrolet Colorado, GMC Canyon). It also powers the Hummer H3. The engine is part of its Atlas family that also includes four- and six-cylinder versions. Since the Volvo 850 was introduced in 1992, many Volvos make use of straight-five engines, often turbocharged. Most of Volvo's current model lineup are powered by inline-five engines (naturally aspirated-five, T5, and even D5) with exceptions marked otherwise (I6, T6, V8). Volvo engines recently found an application in the Ford Focus ST in which the Ford Focus shares its platform structure with the Volvo S40. Volkswagen has used straight-five engines in their Eurovan, and have recently developed a different straight-five engine which is used in the Jetta and Rabbit in North America. Audi's inline-five powered many of the company's bigger models in the 1980s, and was most notably used (in a turbocharged format) in the Audi Quattro racing car. Fiat also makes use of a five-cylinder engine (both petrol and diesel) in larger Fiat, Alfa Romeo and Lancia models.

And personally I prefer straight 6 from BMW....they are really sweet...even at neutral if u rev it...the sound is so intoxicating...however the turbocharged straight 6 from the 335 and 535 is not as smooth as their NA counterpart...

Chevrolet Epica also use inline 6 engine.......for those who is on a budget:)

 

Inline 6 is naturally balance.....:D

No difference in terms of power.

 

However, inline 6 is smoother because its balanced (V6 is not). So, you don't need balancer shafts etc

 

Inline engines are also easier and cheaper to manufacture compared to V6. 1 set of exahust manifold compared to 2 for V6. engine easier and cheaper to cast, 2 camshafts instead of 4. Less coolant/oil lines and plumbing needed. 1 timing chain/belt vs 2 for V6.

 

Downside of inline 6 is the length which requires a big bonnet and weight distribution not as good as V6 which is more compact.
