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 (rear for the Jaguar and 4 x 4 in the case of the Infiniti). The first one has a Jaguar-engineered powertrain under the hood, a 6-cylinder, 24-valves 380hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 405hp 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? On the other hand, taking kerb weight as an important factor into account, the Japanese car offers a considerable difference of 13% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Infiniti does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Jaguar with an average rating of 4.2, and models under the Infiniti badge with 4.6 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 British car rank it on average as 4.5, while the one under the competitor's bonnet gets 3.0 out of 5.

Infiniti is a bit more agile, reaching 100km/h in 0.5 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 250 kilometers per hour, 25km/h less than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 9.1 liters of fuel per 100 kilometers (31 mpg), in combined cycle. We can't ignore that 8% 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 Japanese car offers significantly better overall protection, taking the lead here. From there things take a different direction, with Jaguar offering somewhat better performance, just enough to call it quicker. 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. 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 thousands of similar, yet so different vehicles.
