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 cabriolet 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 550hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 320hp engine designed by Nissan.

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?

I don't like generalizing things when it comes to reliability, although it does seem that Infiniti does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Jaguar with an average rating of 4.1, and models under the Infiniti badge with 4.5 out of 5. Independent research findings rank XK as average reliability-wise, and Q60 is more or less at the same level.Above it all, drivers of cars with the same engine as the British car rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Jaguar is undoubtly more agile, reaching 100km/h in 2 seconds less than its competitor. In addition to that it accelerates all the way to 300 kilometers per hour, 50km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 11.4 liters of fuel per 100 kilometers (25 mpg), in combined cycle. We can't ignore that 8% difference compared to the British car.

Infiniti 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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with Jaguar 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 not difficult to say then that if I'd need to make a choice, it would definitely be the Infiniti. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
