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 4-door sedan body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Jaguar and rear in the case of the Alfa Romeo). The first one has a Jaguar-engineered powertrain under the hood, a 8-cylinder, 32-valves 600hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 510hp engine designed by Ferrari.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the same number of safety stars gained in the process. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, taking kerb weight as an important factor into account, the British car offers a considerable difference of 10% more metal.

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. That's the official data, while our visitors describe reliability of Jaguar with an average rating of 4.1, and models under the Alfa Romeo badge with 4.2 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models 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 a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. In addition to that it accelerates all the way to 322 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy an obvious choice would be the Italian car, averaging around 8.5 liters of fuel per 100 kilometers (33 mpg), in combined cycle. That's 29% difference compared to the British car!

Alfa Romeo 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 significantly better overall protection, taking the lead here. It all continues in the same 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 Alfa Romeo. 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.
