Overview

Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel 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 (rear for the BMW and front in the case of the Honda). The first one has a BMW-engineered powertrain under the hood, a 6-cylinder, 24-valves 245hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by Honda.

Safety

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, with the same number of safety stars gained in the process. 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 it doesn't do much to help us decide between the two. Furthermore, when it comes to weight, a factor that most people underestimate, the Japanese car offers a marginal difference of 1% more metal.

Reliability

I don't like generalizing things when it comes to reliability, although it does seem that Honda is significantly less fault-prone, at least on all of the models level. These are the official statistics, while our visitors describe reliability of BMW with an average rating of 4.1, and models under the Honda badge with 4.7 out of 5. The same official information place 3 Series 21% below average, and Accord 58% above the first one. That apart, owners of different cars powered by the same engine as the German car rank it on average as 4.3, while the one under the competitor's bonnet gets 4.9 out of 5.

Performance & Fuel economy

BMW is way more agile, reaching 100km/h in 3.7 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 38km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.7 liters of fuel per 100 kilometers (50 mpg), in combined cycle.

Verdict

Honda definitely wins the reliability competition, everything taken into consideration. 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. From there things take a different direction, with BMW 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... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
