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 large family 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 BMW-engineered powertrain under the hood, a 8-cylinder, 32-valves 420hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 423hp engine designed by Toyota.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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, if we'd like to consider vehicle mass in this context too, which we definitely should, the Japanese car offers a marginal difference of 1% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Lexus as a brand displays somewhat better results, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of BMW with an average rating of 4.2, and models under the Lexus badge with 4.9 out of 5. The same official information place 3 Series as average reliability-wise, and IS is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Lexus is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. In addition to that it accelerates all the way to 270 kilometers per hour, 20km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 11.4 liters of fuel per 100 kilometers (25 mpg), in combined cycle. We can't ignore that 9% difference compared to the German car.

Lexus is apparently more reliable, not too much, but just enough. 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 Japanese car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Lexus offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! 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. 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™, among thousands of similar, yet so different vehicles.
