2020 Porsche Panamera vs. Mercedes-Benz S-Class

2020 Porsche Panamera vs BMW 7 Series vs Mercedes-Benz S-Class

Drivers looking to make a statement have traditionally turned to full-size luxury sedans for their renowned reputation for unparalleled refinement, sophistication, and elegant exterior styling. A result of their full-size platforms, these striking sedans offer spacious seating adorned with premium comfort and tech amenities to impress even the most discerning passengers.

When comparing models from various manufacturers, many prospective buyers face quite a dilemma thanks to a growing number of choices in this segment. In order to help simplify your decision, Porsche Ann Arbor has created this in-depth comparison guide in which the Porsche Panamera goes head-to-head against the BMW 7 Series and Mercedes-Benz S-Class.

The first competitor to challenge the Porsche Panamera is the BMW 7 Series. Although the BMW 740i begins this matchup with a slight price advantage over the Porsche Panamera, it starts to lose its appeal once you take a closer look at the performance figures of both sedans. Although torque figures are essentially identical, the Panamera has the advantage when it comes to horsepower.

While you might not expect it from a full-size executive sedan, the Porsche Panamera is engineered with legendary Porsche sports car DNA which helps you immediately sense a connection to the road. Other strengths of the Panamera include a 1.5-foot shorter turning radius along with a curb weight that’s 87 pounds lower than that of the BMW 740i. If you’re craving spirited handling and agile maneuverability — the Panamera is the obvious favorite.

Providing the Panamera with its imposing stance are standard 19-inch alloy wheels. Featuring more than good looks, these stylish wheels are wrapped in performance tires designed specifically to deliver exceptional grip and stability during high-speed cornering. Choosing the BMW 740i means that you’ll have to accept run-flat all-season tires which lack the response and feel of dedicated performance tires. Both distinctive and functional, a standard power rear spoiler on the Panamera will deploy at various angles depending on the speed of the vehicle.

Panamera, perfect for carrying a combination of both passengers and gear on your way to your next weekend getaway. BMW shoppers will be disappointed to learn that the rear seat of the 740i is fixed in one position and only features a tiny pass-through slot for longer items. As a result, the Panamera gives you a maximum cargo capacity of 47.6 cubic feet compared to the minuscule 18.2 cubic feet found inside the 740i.

The next challenger to go up against the Porsche Panamera is the Mercedes-Benz S-Class. For this matchup, we’ll compare equivalently equipped versions of the Panamera 4S and the S 450 4MATIC. Although each is powered by a twin-turbo V6 engine and both come equipped with an all-wheel drive system, a closer examination of the performance figures reveals a significant advantage for Porsche.

Driving a Panamera 4S means that you’ll receive 78 more horsepower and 37 lb-ft of additional torque as compared to the S 450 4MATIC. Regardless of the power advantage, the Panamera 4S remains the better option in terms of fuel economy as well. Mercedes-Benz cannot match the city MPG fuel economy rating of the Panamera and the S-Class also has a smaller fuel tank capacity.

You’ll make a statement with the 19-inch alloy wheels found on the Panamera 4S which accentuate the chiseled character lines found in the body. These wheels also come with performance tires which have been engineered to provide drivers with superior response and gripping power during spirited driving. Conversely, the S-Class comes with run-flat all-season tires which have a tendency to dull road feel and compromise performance. A significant 389-pound weight advantage for the Panamera 4S also helps it deliver superlative handling through the corners.

At the rear, a standard power rear spoiler highlights the impressive performance capabilities of the Porsche Panamera 4S. In order to receive a similar feature on the S-Class you’ll be forced to shell out additional cash. If you frequently take extended weekend vacations, the S-Class falls short in terms of its cargo-carrying abilities. Not only does the S 450 offer a laughable 12.3 cubic feet of cargo capacity inside the trunk — the rear seat is also fixed in place and cannot be folded flat. The Panamera 4S features a 60/40 split folding rear seat which can be lowered to create a massive 47.3 cubic feet of cargo capacity.
