• Dragstrip 1/4 mile comparison between the C63 AMG Coupe and Cadillac CTS-V coupe by Insideline

      The C63 AMG coupe and the CTS-V coupe are both beasts in a straight line. Insideline decided to find out which of the two is faster on the strip. The curb weight for the CTS-V is 4200 pounds versus the C63 AMG weighing in at a lighter 3,990. A 6 speed manual was the transmission chosen for the CTS-V while the C63 only has one transmission choice, a 7 speed automatic. The result? The CTS-V wins (barely) with a 12.2@117.5 against the C63's 12.3@116.3. Considering the CTS-V has a motor with a supercharger and barely edges out the naturally aspirated C63 that says a lot about how good the M156 is.

        Hell you can make and LS1 more powerful NA than the M156 and have a ton of money left over.

        if anyone saw the LSX shootout recently there were some NASTY cars going down that dragstrip mid single digits

        Oh I agree I'm just saying it's not just the LSX that can be made beastly. And it becomes difficult to dismiss them as having an inferior design when you see stock block ls1's making twice the NA power of an M156 with less money.

        It can make more power but that doesn't equal superior engineering.

That the record for and N/A lsx is like 8.5 in the 1/4 mile? Hell I bet for the cost of a stock M156 I can get and NA LSX to twice the power and that thing will never break.
        How about that Mercedes is running within a MPH without a blower? I know which motor I find more impressive.

        You know there are big HP Mercedes formula 1 engines? And? Neither of these comes in production cars.

        Than what makes superior engineering? What does it do that an LSX can't for less?

        Once again, dollar per horse is irrelevant. The LS1 is still an ancient design and outdated design compared to the M156.

        I'm sure an LS1 is easily more powerful NA with the right parts than an F430 V8 but I know which motor is truly more impressive.

        It's not difficult to dismiss as an inferior design, it is an inferior design.

        He said for parts... that is with the LSA subtracted. What about tune and labor?

        So what your saying is the performance of a motor is irrelevant in determining which is more impressive? Why because the Ferrari cost 40x's more and is less reliable? Your buying into a brand and not into the bottom line.

        Money per horsepower is irrelevant. Who cares? LSX people care because that is their main argument.

        If wanted dollar per horse I wouldn't drive a BMW. There is something beautiful about a high rpm screamer with a flat curve. The factory LS1 curve falls of a cliff and it is a cheaply designed motor.

        I don't care what it does in the aftermarket with a ton of money thrown at it. It is still a product of inferior engineering.

        Guess I prefer the Porsche GT3 flat-6 to the LSX series.

        What does it do that an LSX can't? How about dual overhead cams?

        You simply are going by horsepower potential in the aftermarket which has nothing to do with the factory cars as presented. Fact is here we have a naturally aspirated 6.2 liter running with a blown 6.2 liter. Uh, someone is doing a better a job designing a motor.

        I'm saying aftermarket performance is irrelevant in determining the better engineered motor which the M156 is. Has nothing to do with the brand. Wonder why no LS series motor has ever won an engine of the year award.

        lol...at the end of the day all i wanna do is go fast....and im pretty sure a highway pull with an LSX against an M156 will ever have the M156 winning that battle

        Most likely not... but that still isn't an LSA that comes with the CTS-V Click here to enlarge

        Well honestly cost has to be factored in because of course the M156 is doing more without the blower. It has 3x's more money put into in from the factory. All the aftermarket components you dismiss have been put in stock on the Benz. You brought up design and I'm telling you without altering the design of the LS(ie I'm not changing the fundamental functioning of the motor) just upgrading components will yield a better result. That is indisputable.

        It's funny because I drove a V and didn't like it much and went out and bought a 550i which doesn't have the potential and aftermarket support the V does and here I am arguing on the other side of the coin but I bought it cause I preferred it as my DD not because it would be easier or cheaper to make power.
