Virtual Adviser's™ opinion

Overview

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 executive car segment and utilize the same 4-door sedan body style and the rear wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a Ford-engineered powertrain under the hood, a 6-cylinder, 24-valves 208hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 231hp engine designed by Mercedes Benz.

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. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the executive car segment, which is generally a fortune safety-wise, but it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, the German car offers a considerable difference of 12% more metal.

Reliability

Reliability is not the best thing to consider on the make level, but it is worth mentioning that both brands display similar results in faults and breakdowns, 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 4.0, and models under the Mercedes Benz badge with 4.4 out of 5. The same official information place XJ 50% below average, and S 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 5.0, while the one under the competitor's bonnet gets 4.2 out of 5.

Performance & Fuel economy

Mercedes Benz is a bit more agile, reaching 100km/h in 0.7 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 25km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 8.2 liters of fuel per 100 kilometers (34 mpg), in combined cycle.

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 German car offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Mercedes Benz 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 really tough to make a final decision here, but if I'd need to, I'd say Mercedes Benz. 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. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser, out of 12.000+ vehicles we currently have in our database.
