Virtual Adviser's™ opinion
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 Subaru and rear in the case of the Lexus). The first one has a Subaru-engineered powertrain under the hood, a 4-cylinder, 16-valves 162hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 207hp engine designed by Toyota.
SafetyThe 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 large family car segment, which is generally a good thing safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, Lexus IS offers a considerable difference of 17% more metal.
ReliabilityManufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Lexus does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Subaru with an average rating of 4.2, and models under the Lexus badge with 4.9 out of 5. The same official information place Legacy as average reliability-wise, and IS is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Legacy rank it on average as 4.8, while the one under the competitor's bonnet gets 5.0 out of 5.
Performance & Fuel economyLexus 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 230 kilometers per hour, 21km/h more than the other car. When it comes to fuel economy the winner has to be Legacy, averaging around 8.6 liters of fuel per 100 kilometers (33 mpg), in combined cycle. We can't ignore that 14% difference compared to Lexus IS.
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 IS beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Lexus being considerably quicker, thus putting more smile on driver's face. 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. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
