Virtual Adviser's™ opinion

Overview

Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the sports car segment and utilize the same 2-door coupe body style and the rear wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Porsche-engineered powertrain under the hood, a 6-cylinder, 24-valves 530hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 262hp engine designed by Jaguar.

Safety

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. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the sports car segment, which is generally classifying them somewhere in the middle safety-wise, still it doesn't help us solve our dilemma, does it? On the other hand, when it comes to weight, a factor that most people underestimate, the British car offers a marginal difference of 9% more metal.

Reliability

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 official statistics, while our visitors describe reliability of Porsche with an average rating of 3.8, 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. That apart, owners of different cars powered by the same engine as the German car rank it on average as 3.0 out of 5, exactly the same as the other one.

Performance & Fuel economy

Porsche is way more agile, reaching 100km/h in 3.9 seconds less than its competitor. In addition to that it accelerates all the way to 329 kilometers per hour, 86km/h more than the other car. When it comes to fuel economy the winner has to be the British car, averaging around 11.3 liters of fuel per 100 kilometers (25 mpg), in combined cycle. We can't ignore that 11% difference compared to the German car.


Verdict

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 outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for the Jaguar. 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, out of 12.000+ vehicles we currently have in our database.
