One of the most popular comparisons these days is the one between the BMW M5 and the new Cadillac CTS-V. We have touched the subject here a few times, with Josh writing a nice article on that, followed by mine which ended with the obvious question: would you choose the CTS-V over the M5?

The fellows at Edmunds Insideline have their own review to show, a review which includes the beautiful, powerful, Mercedes-Benz C63 AMG. We already have seen the Car and Driver magazine taking the Cadillac CTS-V to a race track and scoring better times than the M3 or M5, and apparently, Edmunds believes that the CTS-V is the clear winner in this race, followed closely by the C63 AMG, while our favorite brand finishes last.

I have always said that the combination of price and performance will put the Cadillac on top, but if money was not an issue, I wonder how many people will still choose the M5. 

With this being said, you can read their full article here, along with some great videos.

Once you get your hands on a supercharged 556-horsepower 2009 Cadillac CTS-V, you know that you need a 500-hp 2008 BMW M5 with which to measure it. It’s a matter of practical science.

Of course, there’s a sizable price difference between the $59,995 CTS-V and the $86,675 M5, and we don’t want to get our comparison results skewed by mere money. Maybe we should add the 507-hp 2009 Mercedes-Benz E63 AMG to our science project. Trouble is, this Merc’s $86,875 price tag still doesn’t put the CTS-V under any pressure.

We had a better idea. We opted for the more nimble 2009 Mercedes-Benz C63 AMG. This compact sedan cranks out only 451 hp, but it weighs almost 400 pounds less than the E63, and its base price of $58,075 rings up about $2,000 cheaper than the CTS-V.

Is the 2009 Cadillac CTS-V a true benchmark in the super sedan category? Measured against the pure performance of the 2008 BMW M5 and the value of the 2009 Mercedes-Benz C63 AMG, we knew the truth would come out.

    This comparison doesn’t make sense. The M5 competes with the E63 AMG and would be more inclined to go nose to nose with the Caddy STS-V. I understand that the horsepower is the purpose behind the comparison but you’re essentially comparing cars in different segments. Doesn’t make sense to me.

    I like the CTS-V a lot, especially since it has a proper manual in it. That said, I’d forgo all of these cars and buy an M3 sedan and save $5k over the Caddy.

    @Gragop: I agree. They are comparing apples to oranges. It is like including the M3 in the comparison.

    The comparison therefore is between the M5 and the CTS. I haven’t driven the Cadillac but I respect the company’s history and from the performance figures it seems to be a worthy competitor.
    Finally, if some people buy cars just for the social status then they are low life to begin with.

    The C63 and CTS-V come with a cupful of smug, that’s why you get dipshits like that one at that stoplight, for him it was a “mine is longer than yours” thing. Give me the sophistication and style of the M5 any day, it’s a more adult car. The numbers matter less than the quality of the experience, especially at this price strata.
