Porsche Panamera Interior

The first competitor to challenge the Porsche Panamera is the BMW 7 Series. And right from the beginning, we can see a price advantage for the Panamera. That price advantage becomes enormous when you consider the cost of upgrading to all-wheel drive, a popular option for buyers in Michigan. Since the all-wheel-drive option is so much cheaper on the Panamera, it gives a lot of additional spending power to get the options you want. You can see that the Porsche will hit 60mph a bit sooner, this is thanks in part to its being nearly 600 pounds lighter than BMW.

Weight isn’t the only area where the BMW doesn’t measure up to the Porsche as a driver’s car. The Panamera has a power spoiler, allowing for a more confident sprint up to a top speed that is a whopping 38mph faster than the 740i’s. The performance tires on the Panamera will also deliver more grip than the all-season tires on the 740i, and the low-profile run-flats aren’t great for ride comfort either. The Panamera give you more luggage space, and with 60/40 split-folding rear seats, it also gives you an option for balancing that increased space with passenger space. To go with the wider selection of trim levels, Porsche also gives you quite a lot more options when it comes to paint colors and wheels.

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 500 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 14 more horsepower and 21 lb-ft of additional torque as compared to the S 500 4MATIC. A larger fuel tank means you’ll have to stop less frequently for fuel on your next road trip behind the wheel of the Panamera 4S.

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 518-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 500 offer a laughable 13.8 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.
