Video: 6.2L NA engine vs 5.5L biTurbo engine

[ghibbett]

Autocar have made a 6.2L naturally aspirated engine (C63) versus 5.5L bi-turbo V8 engine (SL63) video: Mercedes AMG V8 head to head - YouTube

 

[sinewave]

I wonder what the aftermarket tuners can do with that twin turbo unit?

Nice t ohear someone praising the downsize. Sounded great on the video.

As Turbo's would easily multiply air volume by a factor of 1.5, the 5.5 litre engine becomes the equivalent of a naturally aspirated 8.25 litre engine

so he turns ESP off to get engines full power? but at no time through the corners can you put full power down, it was all for the drift !

Paid to say the new engine is better I imagine. Clearly it is in terms of mpg/CO2 etc.....but you cannot tell me there is more character than in a huge NA engine....

Erm, it is a huge Turbo engine ......WIN WIN

There will always be NA vs. Turbo debates.....the modern engine and turbo technology covers up many of the negative points that afflicted Turbo engines of the past.

Turbo is the way forward, it won't be long before EVERY engine is turbo charged.

definitely the way forward, but clearly rating it above the NA for character is strange. No doubt it is the better engine and the future.....but a A380 isn't better than a concorde...

SavMan posted up a video on YT which talks in detail about the engine and the lengths they've gone to to minimise lag etc.

I'd much rather have the 5.5TT personally.

Hmmm, not sure I get what you mean....the new engine is still a large V8, so still has that character. Some would say that the old supercharged 5.5 had more character than the 6.2

What a depressingly cynical comment

Not particularly - i think is is consensual the move to TT is the future but they are sole in their choosing of the character over the previous. The fact that there were Mercedes flags everywhere and the rest of the motoring press haven't covered a day (in my reading) where all MBs were available to drive smacks of an Autocar exclusive day.

I'm generally not well renowned for cynicism!

I think there is an endearing hot rod quality about the 6.208 6.3 engine. Though clearly the new motor is a step forward in the right direction.

True re the old supercharged motor - and it was a corker. Much as the 6.3 has been revered as. Maybe the TT will gain the love in due course.

I suppose I in part feel an AMG should be a yah boo sucks to CO2 and MOG - not enough range? Fit the free extended tank a la the old sl55.

Isn't that 'old' MB, producing stupidly big thirsty engines with a relatively low power output?

 

[englishdas]

If this was a Poll, I'd pick the n/a engine every day. Fuel economy and the price of tax discs is irrelevant at these levels of machine.

So saying journalists from the UK's longest-established motoring magazine were being "Paid to say the new engine is better" is not cynical?

I think one of us misunderstands the meaning of the word

Hmmmm are they?

The majority of C63 I see seems to be owned by a guy that only does 5-10k miles a year. That tells me that the guys doing higher mileage shy away from the thirsty V8.

It therefore stands to reason that if they could improve the MPG returns, they might entice the 10-15k miles a year people too.....massive increase in potential customers....

...plus if they left the C63 as is, rising fuel prices would shrink the exisiting demographic......and ultimately kill off the AMG cars.

So all hail the new TT engine

....don't worry too much.....the next one will have a 4 liter engine and an electric one too

Haha. Perhaps. Though please do enlighten me as to what word you would proffer when one magazine runs a test day with no other magazines in situ, and reaches a conclusion seemingly not shared by any other of the less aged but equally respected motoring press.

Perhaps the word you take umbridge with is 'paid'? Would you prefer 'exchanged a resounding tick in the character box to ensure that prospective purchasers are not concerned by other reports to the contrary.'

Cynical? a bit harsh, over analytical perhaps, but a surprising verdict delivered at a day run purely for autocar with every AMG there.....

I'd say the low mileage is pretty indicative of most super hard suspension set up cars. If you do more than 10/12k a year you probably do it for a living or like touring. At which point comfort tends to take over. These cars are not relaxing drives

I am all for the TT engine, and wish my forthcoming car had it for all the sum of its advances, though I would not suggest it is a more characterful engine than a hot rod NA 63
