The Cayenne badge is synonymous with performance, space, and luxury, and for being aPorsche sports car. Thismid-size SUV from Porsche’s stable has been held high, both by enthusiasts and luxury SUV buyers, alike. The Cayenne hybrid model was introduced in 2010 as part of the Cayenne’s second-generation. It was launched around the same time when the whole Volkswagen diesel gate scandal happened (Porsche is owned by Volkswagen).

Currently, in its third generation, the Cayenne hybrid is available in both Coupe and SUV style. When equipped with Porsche’s Sports Chrono package, this five-ton SUV can reach 60 mph in just 4.8 seconds, which is pretty fast for a car that weighs more 5000 pounds. With prices starting from $87,600 fro the coupe-style, and $81,800 for the SUV-styled Cayenne, it all comes down to - where do you wanna see yourself in?

Overall Rating

The E-Hybrid version is an attempt at making the Cayenne greener and more efficient, and we must say that it does that pretty well. The Cayenne’s luxurious interior with leather stitchings, soft-touch dashboard, and a very functional outlook, looks calm and comfortable both from the outside as well as the inside. To top it off, this hybrid SUV has the ability to give you spine-chilling performance for it gets a 3.0-liter V6 engine alongside an electric motor that produces 134 hp, with a combined power output of a whopping 455hp alongside a massive 516lb-ft of torque. The Cayenne competes with the Range Rover Sport and the Mercedes Benz GLE 350 and it gives them all quite a tough battle. Porsche has sold decent numbers of the Cayenne over the years, and we expect the streak to continue with the 2021 Cayenne as well.

2021 Porsche Cayenne E-Hybrid SUV Maintenance, Reliability and Warranty

Porsche is known to make great lasting cars and the Cayenne further strengthens the claim. The car has been on the market for almost 2 decades and even the first-generation vehicles can still be seen on road, and owners are quite happy with their purchase even after such a long time. The Cayenne came out really strong on the reliability front. The Porsche Cayenne is a luxury performance SUV and it does come with the costs of a luxury car, so owning the Porsche Cayenne is going to be a slightly costly affair, as even the regular wear and tear and service are arguably expensive, but it is following segment standards and you will have to shell a similar amount if you buy any of the vehicles in this class.

Reliability and Ownership Costs

The Porsche Cayenne has been a reliable workhorse over the years, and from what we know, customers are more than satisfied with the vehicle. In fact, the Porsche Cayenne gets an 84/100 J.D. Power score and is second only to the BMW X5, making it a great buy. But if you’re buying a car of this class and this price bracket, you’re more or less prepared to bear those costs.

  • Quality and Reliability- 79/100
  • Driving Experience- 87/100
  • Resale- 77/100
  • Dealership Experience- 88/100

When you’re spending a hefty sum on the Porsche, you’re not just spending on the car, you’re spending on a complete lifestyle experience, from the moment you enter the dealership you can feel the exuberance, and all of this carried over to the after-sales service as well. The Porsche Cayenne E-Hybrid is a step ahead to make a greener performance vehicle, and we must say that it has been very well executed. The E-Hybrid packs in the power, punch, and thrill of the standard Cayenne alongside a greener footprint and a smaller fuel bill and all of this can be had at almost no extra ownership costs or maintenance issues.


Porsche offers the Cayenne with an extensive warranty pack that covers the better part of the vehicle and will ensure a relaxed ownership experience. The car comes with a 4-year/50,000-mile limited warranty, a 12-year long life anti-perforation warranty, and a 4-year roadside assistance package.



Limited Warranty

4 year/50,000 miles (80,000 km) warranty for all new vehicles

Corrosion Warranty

12-year long-life warranty against rust perforation in the bodyshell

24-Hour Roadside Assistance

4 year/50,000 miles (80,000 km) warranty for all new vehicles

Porsche has a very good reputation when it comes to making quality cars, and most buyers will not face any issues with the car. Because the modern vehicles have an immensely complex build and pack in a lot of electrical components, which in some cases might malfunction or need a repair, and this is where the warranty comes as a big relief, to both, your mind and your pocket as the Cayenne is an expensive vehicle its spare parts to complement its ticket price.

Miles per Dollar

The modern-day buyer does not only look at the cost of buying the vehicle, but also at owning and maintaining one, and hence, it is important to understand the costs that come along with a vehicle, to make an informed decision. The factors taken into consideration while estimating the Miles Per Dollar figure include fuel costs. Financing, considering a 10% payment upfront, taxes, insurance, depreciation, and normal wear and tear, repairs and scheduled replacement of parts, after-sales and service expenses if any alongside little probability of unforeseen damage or expenses. We assume that an average buyer keeps the vehicle for about 5 years and drives the vehicle for about 15,000 miles a year, this brings us to a tally of about 75,000 miles at the end of 5-years. The estimated cost of owning the Porsche Cayenne E-Hybrid for a period of 5-year after considering all the aforementioned factors is expected to be between $40,000-$42,000, and it surely impresses considering the size, stature, and performance of the vehicle, and this is where you understand the perks of the E-Hybrid and how it helps cut down costs and at the same time reduce your carbon footprint. This brings the Miles Per Dollar figure of the Cayenne E-Hybrid to around 1.8 miles per dollar, which is very impressive for a car like Porsche, and it surely gets a big thumbs-up in this department.


2021 Porsche Cayenne E-Hybrid SUV Buying Advice

The Porsche Cayenne E-Hybrid comes in a single fully-loaded trim level, however, you do get the option between a more powerful and even more performance-oriented Turbo S E-Hybrid variant, which costs way more than the standard E-Hybrid variant, but it does come with mind-boggling performance, and it is truly a performance monster. 

As to which one should you buy; we feel that the standard version will satisfy most users and is more than adequate for the enthusiast as well as the family buyer, however, if you want a complete performance monster and you have the pockets for it, the Turbo S Variant too is a great proposition and it will surely put an evil grin on your face every time you drive it!

Is buying a used Porsche Cayenne E-Hybrid a good idea?

The Porsche Cayenne is quite a reliable vehicle, as we asserted earlier, and the vehicle has been in the market for quite a long time now, so finding a well-maintained example should not be a problem. The vehicle has a very well-engineered and durable motor and tranny, and Porsche has a reputation for making quality cars, so that department is sorted too, however, buying an earlier version means that you will be missing out on a lot of features, as Porsche has made a lot of additions to the Cayenne in recent past, and unless you’re getting a 2019 model car, you will be missing out on the brand-new cockpit inspired interiors, and that is just one item on the list.

The Cayenne depreciates about 19% annually, and as per reports, the best value buy would be a 2017 car, which would be quite easy on the pocket as compared to the current version. Now, coming to the point that you should go for it? If you’re going for an older version and are ready to let go of the modern features, you can go for it as it will save a decent amount of money, but the difference still won’t be too tall as the vehicle holds value quite well. 

For those willing to go for the 2019 iteration, the difference is going to be even smaller, but if you do manage to find an extremely well-maintained example with under 10,000 miles, you can easily save a few thousand bucks and that might be a good value proposition.
