Perfectly suited for drivers looking to make a statement, full-size luxury sedans have a renowned reputation for sophistication, premium refinement, and striking exterior styling. Due to their full-size construction, these luxury sedans feature spacious interiors which are accompanied by comfort and tech features that are sure to impress even the most discerning passengers. Ultimately, many full-size luxury sedan shoppers find themselves faced with a tough decision due to the sheer amount of choices in the segment. To help alleviate some of the confusion, our team has assembled this useful comparison guide in which the Porche Panamera goes up against some of its biggest rivals from BMW, Mercedes-Benz, and Tesla.

19.5 feet ✓ Turning Radius 21 feet
4,157 pounds ✓ Curb Weight 4,244 pounds

First up to face off against the Porsche Panamera is the BMW 7-Series. Although you might not expect it from a full-size executive sedan, the Porsche Panamera is infused with legendary Porsche sports car DNA to help instill a sense of connection with the road. With an 87-pound lower curb weight and a turning radius that’s 1.5 feet shorter than the 740i — the Panamera is clearly the superior option for drivers searching for agile handling and effortless maneuverability.

Giving the Panamera it’s commanding stance are standard 19-inch alloy wheels. Offering more than good looks, these wheels come wrapped in performance tires which are designed to deliver outstanding grip and stability during high-speed cornering. The BMW comes equipped with run-flat all-season tires which lack the feedback of dedicated performance tires. A standard power rear spoiler on the Panamera can deploy at various angles based on the speed of the vehicle.

Shifting our attention towards the interiors of both these sedans, the strengths of the Porsche Panamera continue to shine. A key distinction between the two is that the Panamera offers a 60/40 split folding rear seat that’s perfect for carrying a blend of cargo and passengers on the way to your next ski trip. BMW 740i drivers will be disappointed to learn that the rear seat of their vehicle is fixed and only offers a small pass-through slot for longer items. The end result is a maximum cargo capacity of 46 cubic feet for the Panamera as compared to the laughable 18.2 cubic feet offered by the 740i.

2020 Mercedes-Benz S 450 AWD

$105,000 MSRP $97,250

Performance ✓ Tire Type Run-Flat All-Season

Up next to challenge the Porsche Panamera is the Mercedes-Benz S-Class. In this comparison, we’ll look at equivalently equipped versions of the Panamera 4S and the S 450 AWD. While each offers a twin-turbocharged V6 engine and an all-wheel drive system, a closer look at the performance numbers uncovers a significant advantage for the Porsche. Choosing the Panamera 4S means that you will enjoy 78 additional horsepower and 36 more lb-ft of torque than the S 450.

The Porsche Panamera 4S also includes 19-inch alloy wheels which are larger than those found on the S 450. These stylish wheels come wrapped in performance tires which are designed specifically to deliver greater response and gripping power during spirited driving. On the other hand, the S-Class comes with run-flat all-seasons which can lack road feel and compromise performance. A 389-pound weight advantage for the Panamera 4S also helps it deliver superlative handling through the corners.

A stylish power rear spoiler hints at the capable performance of the Porsche Panamera 4S. You’ll be required to spend extra cash on a similar feature at Mercedes-Benz. If you’re the type of driver that loves to bring all of your gear along for your next vacation, you’ll find yourself disappointed by the S-Class. Since the rear seat of the S 450 is fixed and cannot be folded flat, it offers a minuscule 12.3 cubic feet of cargo capacity in the trunk. The Panamera 4S has a 60/40 split folding rear seat which can be lowered to create a massive 46 cubic feet of cargo capacity.

Porsche Panamera vs Tesla Model S

2020 Tesla Model S

2020 Tesla Model S 100D AWD

$105,000 MSRP $99,990
4.0 seconds (with optional Sport Chrono Package) ✓ 0-60 Time 4.1 Seconds
179 MPH ✓ Top Track Speed 155 MPH
4,296 pounds ✓ Curb Weight 4,736 pounds
663 miles (28 hwy MPG x 23.7 gallons) ✓ Highway Range 335 miles
Performance ✓ Tire Type All-Season
Standard ✓ Power Sunroof Optional
Standard ✓ Satellite Radio Optional
Standard ✓ DVD Entertainment System Optional

Our third and final vehicle to go up against the Porsche Panamera is the all-electric Tesla Model S. Although Tesla likes to tout its instantaneous response and pure electric powertrain, let’s see how exactly how the Model S 100D stacks up against the impressive Panamera 4S.

When equipped with the optional Sport Chrono Package, the Panamera 4S can accelerate from 0-60 MPH quicker than the Model S. Furthermore, the Model S 100D reaches its maximum speed at 155 MPH. The Porsche can continue on to a top track speed of an astounding 179 MPH for maximum thrills. A massive 440 pounds of additional weight on the Model S 100D AWD certainly puts the Tesla at a disadvantage. Standard performance tires help the Panamera S excel in the corners and from a dead stop as compared to the inferior all-season tires found on the Tesla.

You’d think a plug-in electric sedan would have the advantage on extended road trips. Unfortunately for Tesla owners, they will find themselves out of charge after just 335 miles of range. Even if they’re lucky to find a charge station on the Supercharger network on the way to their final destination, at best they will spend a minimum of 30 minutes to receive a full charge. A quick stop at the gas station only takes a matter of minutes to fill up your Porsche Panamera 4S.

When it comes to premium features, the Porsche is the better choice. Open the standard power sunroof inside the Panamera 4S to fill the cabin with natural lighting and fresh air. Boredom is a thing of the past inside the Porsche thanks to standard satellite radio and a DVD entertainment system. All three of these great features will require you to spend even more at Tesla, bringing its standing MSRP perilously close to the Porsche Panamera 4S.

Now that the results are in, it’s obvious that the best choice among this group of luxury sedans is the Porsche Panamera.
