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 'Luxury car' segment, the only major difference here really is their wheel drive configuration (rear for the Mercedes Benz and front in the case of the Audi). The first one has a Mercedes Benz-engineered powertrain under the hood, a 4-cylinder, 16-valves 136hp unit, while the other one gets its power and torque from a 4-cylinder, 20-valves 130hp engine designed by Volkswagen.
SafetyBoth vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Mercedes Benz being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the luxury car segment, which is generally a very 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, Mercedes Benz E offers a marginal difference of 1% more metal.
ReliabilityReliability 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, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the Audi badge with 4.2 out of 5. Independent research findings rank E as average reliability-wise, and A6 is more or less at the same level.Above it all, drivers of cars with the same engine as Mercedes Benz E rank it on average as 4.0, while the one under the competitor's bonnet gets 4.9 out of 5.
Performance & Fuel economyAudi is a bit more agile, reaching 100km/h in 0.3 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 205 kilometers per hour, 4km/h less than the other car. When it comes to fuel economy the winner has to be Audi A6, averaging around 8.3 liters of fuel per 100 kilometers (34 mpg), in combined cycle. We can't ignore that 12% difference compared to Mercedes Benz E.
Verdict
Audi 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, Mercedes Benz E offers much better overall protection, which launches it ahead of the other contender. From there things take a different direction, with Audi offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! No mistake, whatever you decide here, but I'd still go for the Audi. 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.
