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 luxury car segment and utilize the same 4-door sedan 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 Toyota-engineered powertrain under the hood, a 6-cylinder, 24-valves 252hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 320hp engine designed by Nissan.

Safety

The fact that the Lexus got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, puts it sky-high safety-wise, in my eyes at least. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the luxury car segment, which is generally a very good thing 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, Infiniti G offers a marginal difference of 1% more metal.

Reliability

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Lexus does have a slight advantage, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Lexus with an average rating of 4.9, and models under the Infiniti badge with 4.6 out of 5. Some independent research have also placed GS 30% above average, and G those same 30% below the first one. That apart, owners of different cars powered by the same engine as Lexus GS rank it on average as 5.0 out of 5, exactly the same as the other one.

Performance & Fuel economy

Infiniti is undoubtly more agile, reaching 100km/h in 1.4 seconds less than its competitor. In addition to that it accelerates all the way to 249 kilometers per hour, 9km/h more than the other car. When it comes to fuel economy the winner has to be Lexus GS, averaging around 9.5 liters of fuel per 100 kilometers (30 mpg), in combined cycle. We can't ignore that 11% difference compared to Infiniti G.

Verdict

Lexus 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, Lexus GS beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with Infiniti outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... All together, there's not much more to say, in this case I wouldn't even consider anything but Lexus. 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.
