No worries.. GT-R spec V to the rescue! lol

 

6.2 V8 developed by AMG > 3.8 V6

The C63 is detuned and all motor producing these types of numbers. The GT-R is highly tuned with twin air compressors aiding it.

 

Well looking at C&D IS-F numbers when it was tested by itself, it actually is 2nd fastest. Not bad considering its down about 50 horses.

 

Right, but if Lexus had put the same hp/litre in the V-8 they currently have in the V-6, we wouldn't be down on power or second in class. It's a huge disappointment IMHO.

 

I would think it would be easier to mod a factory TT GTR then the C63. You can't compare a modded car to a stock car or modded cars to modded cars since those vehicles dont take reliability into consideration.

are you serious? then why was the V6 TT by Toyota (Supra) one of the greatest engines to ever be built?

if the size of the engine is all that matters, Viper takes the crown.

btw, before you make a ignorant post, did you even know the GTR is ULEV? which means IT was also probably detuned.

 

I hope that instead of this ongoing horsepower war, that for the next generation, this class of cars.......hell all cars, focus on major weight reduction with a slight power increase, rather than sending the HP through the stratosphere.

 

Because the supra never had a V6

 

I'm pretty sure it'll be much easier to mod a gt-r with factory turbo's than a mercedes na 6.2 liter. Even IF you mod the c63 to like 800hp or something you wont get that power to the ground as well as with the GT-R's awd system.

 

First, let's stop with the unnecessary comments.

Second, the TT Supra has an I-6, not a V-6. Toyota has never produced a turbo V anything. While the 2JZ is legendary, it's only legendary when you consider it MUST run race gas to make big power. It can't do it with pump gas. The same will be true for the GTR. Sure, you'll be able to bump up the boost, but only if you're running 100 octane or better. The big MB will not hit this wall until you're well over 500 hp, and NA engines can be made to be far less fuel sensitive than boosted engines for a lot of reasons. So all the arguments go in MB's favor here.

Third, ULEV has nothing to do with tailpipe emissions. ULEV addresses hydrocarbon emissions through evaporation, not tailpipe, so saying it is detuned to meet ULEV is way off base.

 

Detuned from what? If anything, the GTR is probably the first nissan to use the 3.8L V6 TT. It can't really be detuned for now.. Having high horsepower nowadays doesn't you can't meet ULEV status. Technology and cars work hand in hand to provide a more efficient way of making use of the fuel. It doesn't have to be an emission puffer to make power.

 

Bit of an oxymoron of a post there wouldnt you say?

Anyway, Lobux and GSteg pretty much addressed your post so I'll leave it at that.

As far as the next gen of these cars focusing on weight reduction, I don't see that happening. Really, the only way to achieve that goal is to use very expensive materials which would bring the cost way up, or to strip the vehcile of it's options and luxury amenities. Keep in mind, these are not sports cars or roadsters, they are luxury sports sedans and will likely always carry a good amount of weight with them.

 

The IS-F is detuned for fuel economy (which results in a small gas guzzler tax in North America), and it's also tuned for lower C02 *tailpipe* emissions in Europe which translates to less taxes as well.

Back on topic, the C63 is an awesome car. If I had the money, I'd love to have a C63, M3, and IS-F all at once.

 

Benz are doing something similar to what the American car companies do: put a huge engine into the car to squeeze out the most number of horsepower and torque. I don't like this way. I like the Japanese way, using a reasonably big enough engine and add turbochargers to it. I am sure C63 is very fast, but of course it is fast it has a 6.2L engine for god sake.

 

Only problem with that is that there are very few japanese cars using turbo's these days. Supra's gone, 3000GT is gone, 300ZX is gone, RX7 is gone. All their replacements (if there is one) are all motor. With the exception of the GT-R what other fast japanese car is using turbo's???

 

WOW
