Overview

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.

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. 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 Japanese car offers a considerable difference of 13% more metal.

Reliability

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. These are the results of an independent reasearch, 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. We should definitely mention that owners of cars with the same powertrain 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.

Performance & Fuel economy

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.

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 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. 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.
