Porsche Panamera vs Mercedes-Benz S-Class, Lexus LS, BMW 7 Series 

When you’re laying down over $60k for any vehicle, you have a certain set of expectations that need to be met. The Porsche Panamera is a high-performance luxury sedan from a company that isn’t usually associated with sedans at all, but it delivers Porsche quality, innovation and performance in a four-door package. Its V6 delivers a robust 330 hp in base trim and a whopping 680 hp for the plug-in hybrid version. That translates to a 0-60 time of 5.4 seconds for the base engine or a rocket-sled-like 3.4 seconds for the top-line hybrid. It’s truly a driver’s car, with a supple and comfortable interior, a forgiving ride and surefooted handling thanks to Porsche’s Active Suspension Management, which adjusts the suspension on-the-fly to adapt to road conditions.

The Panamera’s slippery shape exudes Porsche style, with a surprising amount of cargo space (especially compared to the M-B S-class). and it delivers surprisingly good fuel economy on the highway. Let’s see how the Panamera looks when you compare it to the Mercedes-Benz S-Class, Lexus LS and BMW 7 Series.

Porsche Panamera Power Comparison

  Porsche Panamera Mercedes S-Class Lexus LS  BMW 7 Series
Max. Power 330 hp 362 hp 416 hp 320 hp
Max. Torque 331 lb-ft 369 lb-ft 442 lb-ft 330 lb-ft
Engine 3.0 liter intercooled turbo V6 3.0 liter twin-turbo V6 3.5 liter V6 3.0 liter intercooled turbo V6
0-60 mph 5.4 seconds 5.3 seconds 5.8 seconds 4.8 seconds

Make no mistake: these are all outstanding world-class sedans, and each car brings a lot of quality and performance to the table. All have fine handling and road manners, and each has a well-thought-out interior with plenty of innovations and cutting-edge amenities. On paper, it would seem that the Lexus LS is the stronger performer, considering its horsepower rating, but in real-world numbers all four are pretty closely matched when it comes to acceleration. Let’s move on to fuel economy rankings:

City/highway MPG 19/28 19/28 19/30 22/30


Again, this is a pretty close matchup between all four makes and models. The Panamera does deliver better fuel economy (and performance) if you opt for the hybrid, bumping fuel economy up to 46 mpg on the highway. This 680-horsepower drivetrain option puts the Panamera into supercar territory, with a jaw-dropping 0-60 time of 2.9 seconds.

These are all big, bulky cars, with the Lexus in particular tipping the scales at nearly 5,000 lbs, which is considerably more than an old Lincoln Town Car. The Panamera’s soul is all Porsche, with handling and performance that rival the 911 -- except with four doors instead of two. At the heart of the Panamera’s performance is the steering-wheel-mounted driving mode dial. Changing from one mode to another means modified shift points, more power and throttle response and changes in ride quality and handling that are tailored for Sport or Normal. In addition, the smart suspension can tweak itself on the fly to compensate for road conditions. Finally, the Panamera is available with all-wheel-drive for amazingly sure-footed road manners and traction. All in all, it’s a package of top-shelf performance, luxury, engineering and quality that the BMW, Lexus and Benz just can’t match.
