Virtual Adviser's™ opinion
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 Jaguar-engineered powertrain under the hood, a 8-cylinder, 32-valves 385hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 400hp engine designed by Porsche.
SafetyUnfortunatelly, 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? Furthermore, when it comes to weight, a factor that most people underestimate, the British car offers a considerable difference of 17% more metal.
ReliabilityManufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Jaguar does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Jaguar with an average rating of 4.1, and models under the Porsche badge with 3.7 out of 5. Some independent research have also placed XK as average reliability-wise, and 911 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the British car rank it on average as 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.
Performance & Fuel economyPorsche is undoubtly more agile, reaching 100km/h in 1 seconds less than its competitor. In addition to that it accelerates all the way to 304 kilometers per hour, 54km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 9.5 liters of fuel per 100 kilometers (30 mpg), in combined cycle. We can't ignore that 18% difference compared to the British car.
Verdict
Jaguar is apparently more reliable, not too much, but just enough. 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 significantly better overall protection, taking the lead here. 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! I believe that, when we take all into account, we have only one winner here - the 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.
