Overview

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 (front for the Mazda and rear in the case of the Lexus). The first one has a Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 145hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 245hp engine designed by Toyota.

Safety

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. Still, apart from the official crash test results there are other things we need to be aware of. 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, when it comes to weight, a factor that most people underestimate, Lexus IS offers a potentially life-saving difference of 32% 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, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Mazda with an average rating of 4.5, and models under the Lexus badge with 4.9 out of 5. The same official information place 6 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 Mazda 6 rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Performance & Fuel economy

Lexus is undoubtly more agile, reaching 100km/h in 2.5 seconds less than its competitor. In addition to that it accelerates all the way to 230 kilometers per hour, 22km/h more than the other car. When it comes to fuel economy the winner has to be Mazda 6, averaging around 5.5 liters of fuel per 100 kilometers (51 mpg), in combined cycle. We can't ignore that 27% 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 offers much better overall protection, which launches it ahead of the other contender. 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... No mistake, whatever you decide here, but I'd still go for the 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.
