First Test: 2011 Porsche Panamera Turbo – Hey Cadillac, About That "World's Fastest Sedan" Commercial…

Yes, folks, there’s a new sheriff in town. Sure, he looks…different. He’s got a funny name and he’s fresh off the boat from the old country, but he means business. He’s also looking for an outlaw by the name of CTS-V who claims to be the fastest production sedan…in the world. Commence semantic quibbling over what the Porsche Panamera is. It’s a sedan…wait, no, it’s a hatchback. A wagon? Who knows. It doesn’t matter, really. It’s fast; faster than any Cadillac CTS-V you can throw at it.

But wait, the CTS-V is a damn fast car, ain’t it? You bet it is. The sedan will blast 60 mph in 4 seconds flat. The Coupe? 4.1 seconds. The Wagon? 4.2. Few sedans can tangle with this Caddy and win. The Panamera is one of them. Oh, did we mention the Panamera gets better gas mileage, too…


How? As any poker player will tell you, a pair beats a high card. One supercharger, no matter how super, simply ain’t a match for twin turbos. Put another way, the Caddy’s 8.7 psi of supercharger boost can’t hold a candle to the 12 psi available from the Porsche’s twin turbos, much less the 13.2 psi on tap thanks to the overboost feature as part of the Sport Chrono Package Plus our test car came equipped with.


Hang on a minute, though. The CTS-V’s 6.2-liter V-8 makes 556 horsepower, while the porky Porsche’s little twin-turbo 4.8-liter V-8 makes just 500 horsepower (which we suspect may be underrated). True enough, but the Porsche pounds out some 563 pound-feet of torque to the Cadillac’s 550 pound-feet. But the Cadillac weighs less. Also true, as our Panamera Turbo weighed in at a portly 4486 pounds, more than 100 pounds heavier than the weightiest CTS-V we’ve tested and 300 pounds heavier than the lightest. Still doesn’t matter.
