Me too, the only MB I am interested in.

Yeah, I was interested too.

 

[GTA45E]

No word yet on the price target of the GT?
It will have a higher sticker than the SL which would put it out of range with the Jaguar F-Type V8.

 

[LaArtist]

^Lol it said when driving performance is more than just a phrase..

I said to myself; Oh you mean like BMW and Ultimate driving machine?

Video said yes back


PS
Let't the dislikes hail on my naked body.. idgaf!!!

YIEAAAH livin on the edge!

Serves BMW right. I remember tests pitting the Z4M Coupe against the Cayman S, which even then was nipping at 911 tails, and the Z4M feared quite well. If BMW had continued development of the Z as a sports car instead of making it a luxury cruiser they might have had a high performance platform to rival this GT. Pity.

Official - Mercedes-AMG GT to get new 503bhp (375 kW) twin-turbo engine

The upcoming Mercedes-AMG GT will be powered by a twin-turbocharged four-valve-per-cylinder 4.0-litre V8 petrol engine, the German car maker has officially confirmed.

In its initial state of tune, the unit will develop 503bhp at 6250rpm and 479lb ft of torque on a band of revs between 1750 and 4750rpm.

The all-new 90-degree quad-cam direct-injection unit, known internally under the codename M178, has been developed from the ground up as a replacement for AMG’s existing naturally aspirated 6.2-litre V8, the M159, which is being phased out after four years, following the end of production of the SLS AMG in both coupé and roadster guises.

AMG’s new sand-cast aluminium block engine, also slated to power the upcoming replacement for the C63 AMG, boasts the same 83mm and 92.0mm bore and stroke measurements as the Mercedes-Benz performance car division’s highly strung 355bhp turbocharged 2.0-litre four-cylinder direct-injection powerplant, as used by the A45 AMG and CLA45 AMG, giving it an overall swept volume of 3982cc.

Boosting induction are a pair of Borg Warner produced turbochargers mounted atop the engine within the space between the two cylinder banks – a layout AMG engine boss, Christian Enderle, says helps make the M178 some 88mm shorter than the M159 engine. The turbochargers, which operate in a parallel state at a maximum pressure of 2.3 bar, are cooled by a water-to-air intercooler.

Other technology included on AMG’s second turbocharged production car engine is a Bosch-supplied piezo injection system, capable of providing up to seven individual injections per cycle, cylinder barrels finished with Mercedes-Benz’s patented Nanoslide friction reducing material, a cylinder head produced from a lightly Zirconium-refined aluminium and dry sump lubrication.

The exhaust is rooted from the turbochargers high up in the middle of the engine, providing the M178 with what is known as a 'hot inner vee'. Initial aural impressions of the new powerplant on a test bed at AMG’s headquarters in Affalterbach, Germany, reveal it retains the characteristic baritone exhaust note as its predecessor.

With a specific output of 126.3bhp per litre, the turbocharged M178 engine slated for the new GT develops a significant 35.6bhp more per litre than the naturally aspirated M159 unit fitted to the standard SLS AMG.

But with a swept volume that is a considerable 2226cc less than its predecessor, its overall 503bhp is down by 65bhp on the engine it replaces in its initial state of tune. Peak power is also developed 750rpm earlier in the rev range at 6250rpm.

The new AMG engine’s 479lb ft of torque is the same as that offered by the standard M159 unit. However, it is developed 3000rpm earlier in the rev range at 1750rpm and continues on a plateau through to 4750rpm.

Only 479lb of torque??? Disappointing.

 

[Wolfgang]

^ Maybe. However, max torque is already available at 1750 rpm (shown in red).

 

[GTA45E]

Assuming it`s going to use the same transmission as the SLS, this torque figure might be all it can handle for now.
Love the specs but whats up with our favorite German brands and these flimsy looking engine covers. All of them seem to be guilty of it...
Heck, some of our American brands have better looking covers. Take the 15 Corvette Z06 for example... the cover bolted on the engine and simply looks more race-inspired.

 

[Zafiro]

So 510 hp/650 nm for the new C63 AMG?

Only 479lb[650 Nm] of torque??? Disappointing.

- more than enough to move ~1,500 kilos of AMG GT.

Consider that the same kind of engine - the Audi/Bentley 4.0 V8 biturbo - 'only' has 680 Nm to motivate 2.3 tonnes of Bentley Continental GT.

Given that the 'sister' engine - the 2.0l I4 'M133' - produces 450 Nm with 1.8 bar of boost pressure, then 700 Nm plus should be easily achievable for this new AMG engine at higher boost pressures in heavier cars, like the W205 C63 AMG and so on.

whats up with our favorite German brands and these flimsy looking engine covers

it might be to do with not trapping in the huge heat generated from the turbos in the V.

Putting a glorified tea tray on top instead of a more eye-pleasing dressed engine shroud could be the necessary pay off of having all that within-the-'V' turbo response efficiency, and the perhaps better option to us enthusiasts of leaving it naked, would draw all the shyster lawyers in for claims caused by people burning themselves or having their eyebrows singed bending down to inspect all that lovely pipework.

 

[martinbo]

Here it is again - reverse flow + hot-side inside turbocharging. Brought to you by BMW - well before anyone else. Now it seems to be the high-performance industry standard...

Don't flame me for IC-level comment. Simply pointing out an observation.

Notice though that AMG eschews both twin-scroll and cross-manifold tech for a simpler (probably better sounding too) configuration:

 

[merc4]

if the torque figure is correct it has less specific torque than the 3,0 V6 TT in the 450. Well it is only the first version, mathematically it should have no problems to deliver at least 650 PS and 850 NM.

 

[Amat46]

 

[LaArtist]

Yes..they might have cracked the code to good sounding turbo engines..

Take note industry.. and especially poor BMW

 

[PINHEAD]

I like the SLS AMG, too, but this seems to be the real successor of the legendary 300 SL.
I mean the appearance.

A tee little disappointed in the power and torque figures but it is only initial tune so we can expect big gains in future! Lets hope the AMG GT will weigh less than 1500kg and then it should produce good performance! But it is 10hp less than the 911 Turbo so will this car then compete with 911 Carrera S?

Incredibly light lump, it something wonderful will be...
