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 420hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 370hp 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. Moving further on, let's take a closer look at some additional safety-related facts. 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, if we'd like to consider vehicle mass in this context too, which we definitely should, the British car offers a marginal difference of 6% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Jaguar does have a slight advantage, all the models observed together. These are the official statistics, 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. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. Above it all, drivers of cars with the same engine as the German car rank it on average as 3.0, while the one under the competitor's bonnet gets 2.0 out of 5.

Porsche is undoubtly more agile, reaching 100km/h in 1.2 seconds less than its competitor. In addition to that it accelerates all the way to 305 kilometers per hour, 55km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 12.7 liters of fuel per 100 kilometers (22 mpg), in combined cycle.

Porsche 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. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say Jaguar. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
