2025 Porsche Cayenne S E-Hybrid Coupe Vs. 2025 BMW X6 M60i

Key differences: 2025 Porsche Cayenne S E-Hybrid Coupe Vs. 2025 BMW X6 M60i

Both the Cayenne S E-Hybrid Coupe and the BMW X6 M60i are high-end luxury SUVs, but they have some significant differences. The first is price: The Cayenne S E-Hybrid Coupe will set you back $110,400, which makes it $16,100 more expensive than the BMW X6 M60i. For the extra cash, you’re getting a Porsche badge, and some added luxury features such as soft-close doors, Matrix LED headlights, full leather seating, and adaptive air suspension.

However, the X6 M60i isn’t lacking in terms of luxury features either. You get 16-way power-adjustable front seats, heated and ventilated front seats, and a massive curved display on the dashboard consisting of a 12.3-inch driver information display along with a 14.9-inch touchscreen infotainment screen. It even packs a flagship 600-watt Harman Kardon Surround Sound audio system, which is standard. The Porsche meanwhile, only gets a 10-speaker 150-watt system, and the Bose and Burmester options are $1,200 and $7,000 respectively.

Practicality is also a deciding factor in choosing Coupe SUVs because they don’t offer much cargo volume of a traditional SUV, with the sloping roofline. Surprisingly, the BMW X6 M60i aces ahead with 27.4 cubic feet, as opposed to just 15.3 in the Cayenne S E-Hybrid Coupe. The main reason why the Cayenne Coupe has lesser room in the trunk is because of the battery pack, which Porsche has tucked over the rear axle, taking up precious cargo room in all the Cayenne E-Hybrid models.

Performance: 2025 Porsche Cayenne S E-Hybrid Coupe vs. 2025 BMW X6 M60i

Apart from the obvious differences between the Cayenne S E-Hybrid Coupe and the X6 M60i, they share different powertrain configurations. I’m talking hybrid versus pure gas engines (if you don’t consider mild hybrids, true hybrids). Starting with the Porsche: it comes with a 3.0-liter turbocharged V6, the same as the base model, but the e-motor provides enough boost to produce a total of 512 horsepower and 553 pound-feet of torque. For context, this is 164 horsepower more than the standard Cayenne Coupe and 50 more than the entry-level Cayenne Coupe E-Hybrid.

The X6 M60i, on the other hand, features a 4.4-liter twin-turbo V8 with a 48-volt mild hybrid system. This is the newer S68 engine, which also powers the new BMW G90 M5, and it’s rated at 523 horsepower and 553 pound-feet of torque. The V8 indeed packs a mild hybrid, but it isn’t as effective as a PHEV like the Cayenne S E-Hybrid Coupe. The mild hybrid system helps with efficiency in stop-start traffic situations and eases out low-speed engine load.

Speaking of the hybrid system, the Cayenne S E-Hybrid also benefits from all-electric driving for short periods (about 20 miles per full charge), thanks to the 25.9 kWh battery pack. In electric mode alone, this Coupe SUV can run as fast as 84 mph! If you consider the Cayenne S E-Hybrid, you can run most of your errands without turning on the V6, and your neighbors will be happier, which is unlikely for the X6 M60i.

As for the drive type and gearbox, both the Porsche and the Bimmer come with all-wheel drive as standard and an eight-speed ZF torque converter automatic gearbox. According to Porsche, the Cayenne S E-Hybrid Coupe can get to 60 mph from a standstill in 4.4 seconds, which is two-tenths of a second slower than what BMW estimates for the X6 M60i. The Bimmer might be quicker off the line, but the Cayenne S E-Hybrid can go as fast as 163 mph, while the X6 M60i’s top speed is electronically capped at 155 mph.

Coming to chassis features, the X6 M60i is more capable on paper. Features like a rear limited-slip differential, rear axle steering, and a more capable braking system should make it a better driver’s car than the Cayenne S E-Hybrid Coupe. However, if you prefer better ride quality, the Cayenne should be a no-brainer, thanks to the air suspension system. So given a choice, which one of these two SUVs would you choose? Personally, I’d pick the BMW over the Porsche, because it’s cheaper, features more chassis tech, and has a good ol’ V8 roar. Also, I speculate that after five years of owning it, I wouldn’t feel bad about the depreciation, as much as a Porsche Cayenne S E-Hybrid would.
