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 8-cylinder, 32-valves 348hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 320hp engine designed by Nissan.

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. Moving further on, let's take a closer look at some additional safety-related facts. 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? Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Lexus GS offers a marginal difference of 6% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Lexus does have a slight advantage, when all the models are taken into account. That's the official data, 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. The same official information place GS as average reliability-wise, and G is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Lexus GS rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Both of the cars accelerate exactly the same, so we couldn't put one above the other. Car No. 1 reaches top speed of 249 kilometers per hour, 1km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 10.8 liters of fuel per 100 kilometers (26 mpg), in combined cycle.

Infiniti 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. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Infiniti G still consumps less fuel, which needs to be taken into consideration. It's not difficult to say then that if I'd need to make a choice, it would definitely be the Lexus. 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.
