Porsche has recently fielded their first 4-door sedan, the Panamera. The new Porsche Panamera is sort of a low-flying variant of the Porsche SUV, the Cayenne. It uses similar nomenclature, and powertrains as the SUV. The Panamera has widely been panned for its visual appeal (or lack thereof), but I am a function over form person. I am also a Porsche fan from way back, so let’s see how the new German compares with Cadillac’s CTS-V Supercar Sedan.

The Porsche Panamera comes in S, 4S, and Turbo Variants. The Panamera S, which starts at $90.7K, is the Panamera model that is likely to be cross-shopped with the $60.7K Cadillac CTS-V.

Conclusions?
- The more expensive, Porsche Panamera Turbo, at 500 hp, comes closer to CTS-V performance than the Panamera S model, but is unlikely to be directly shopped with a CTS-V since it costs roughly twice as much as the Cadillac.
- The CTS-V has more power, at 556 hp/551 lb-ft vs 400-hp/369 lb-ft for the Porsche Panamera S, but weighs slighly more at 4,300 lbs vs 4,137 lbs.
- The CTS-V acceleration numbers are notably stronger, with an advantage of 0.8 sec 0-60, at 4.3 sec for the Cadillac vs 5.1 sec for the Porsche. At the quartermile the difference is still 0.9 sec, placing these two cars in different classes for acceleration. Cadillac CTS-V: 12.6 @ 114.6 mph Porsche Panamera S: 13.5 sec @ 105.8 mph
- Cornering: The Porsche has the advantage here, pulling 0.94 g’s on the skidpad vs 0.93 g’s for the Cadillac. However, the CTS-V powers ahead in the Figure-8: 25.1 sec @ 0.75 g (avg) for the Cadillac vs 25.7 sec @ 0.72 g (avg) for the Porsche.
- The Porsche has the advantage in fuel economy, at 16/24 mpg city/highway vs a thirsty 14/19 mpg city/highway for the Cadillac.
- The CTS-V is almost $30K less expensive than the Porsche, with the Cadillac CTS-V at $60.7K, and the Porsche Panamera S at $90.7K (starting prices).
