US$150,000 Porsche Panamera Turbo vs the US$86,000 Cadillac CTS-V: how do they compare?

Read on for a comparison between perhaps the greatest sedan in existence and the extreme value proposition

The Porsche Panamera is an incredible machine – so incredible that we named it Business Insider's 2017 Car of the Year.
The Panamera in Turbo trim is monumental: There is a stonking twin-turbocharged, 4-litre V8 under the bonnet, cranking out 550 horsepower. But behind that motor is a cabin of unparalleled luxury.
For those who want it all, the Panamera Turbo does not disappoint. But it will cost more than US$150,000. One does not get to be a Porsche owner without doing some damage to the bank account.
That is a rich sticker, but for about half the price you can get your hands on even more power. It won't be German power – it will be Detroit oomph. And it will have a Cadillac badge.
The CTS-V is probably my favourite high-performance four-door on Earth. If you like the Corvette Z06 and its 6.2-litre, 650-hp V8 widow-maker, the CTS-V has the same power plant, just tuned down by 10 horses, to 640. You would be hard-pressed to notice the drop in power. In both the Caddy and Vette, you are getting extreme performance at a cost that is difficult to overlook.
Let us call this comparison a showdown between perhaps the greatest sedan in existence and the extreme value proposition. Read on to see who wins.
The CTS-V in “Red Obsession”. I enjoyed the vehicle immensely. Our test car cost over US$90,000 and was very well-optioned. The base cost of the CTS-V is about US$86,000.
The “V” cars are Caddy's answer to high-performance versions of European sports sedans: BMW’s M Sports, Mercedes-AMGs and the Audi RS. And, of course, dedicated high-end rides such as the Panamera.
