Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 2-door coupe body style within the same 'Sports car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Porsche and rear in the case of the Jaguar). The first one has a Porsche-engineered powertrain under the hood, a 6-cylinder, 24-valves 560hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 550hp engine designed by Jaguar.

Unfortunatelly, neither of the two vehicles was submitted to the European New Car Assessment Programme (Euro NCAP) testing. This makes it virtually impossible for me to pick one over the other and I'm generally against buying such cars as the safety should really always come first. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the sports car segment, which is generally classifying them somewhere in the middle safety-wise, but it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, the British car offers a marginal difference of 9% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Jaguar does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Porsche with an average rating of 3.7, and models under the Jaguar badge with 4.1 out of 5. Some independent research have also placed 911 as average reliability-wise, and XK is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 3.0 out of 5, exactly the same as the other one.

Porsche is undoubtly more agile, reaching 100km/h in 1.3 seconds less than its competitor. In addition to that it accelerates all the way to 318 kilometers per hour, 18km/h more than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 9.7 liters of fuel per 100 kilometers (29 mpg), in combined cycle. That's 27% difference compared to the British car!

Jaguar appears just a bit more reliable, although the difference is truly marginal. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In my opinion, everything taken into account, the British car offers slightly better overall protection and takes the lead. From there things take a different direction, with Porsche being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but Porsche. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among more than 12.000 different ones in our database.
