I read today's AutoBild review on the Audi A6, BMW 5 Series, and E-Class. I'll keep the conclusion briefly, focusing on the BMW 5 Series and the Mercedes E-Class.
All three cars were equipped the same, the Audi missed out on Matrix LED lights though.
The Mercedes provides better acceleration at higher speeds (>130 km/h), slightly higher top speed, consumes the least fuel, exhibits superior braking performance with warm brakes, offers significantly more interior space, has the highest payload, and the smallest turning radius. Additionally, it is quieter inside.
The BMW is faster up to highway speed, on par in terms of infotainment, has better braking performance with cold brakes, can carry the highest roof load, and costs considerably less than the E-Class with the same features.
The E-Class excels in almost all aspects but comes at a significantly higher cost than the new 5 Series, which wins overall due to strong performance in every discipline.
The BMW and Mercedes have similar weights and drive almost identically, making them equal in terms of comfort and dynamics. It's no longer just a 'BMW or Mercedes' choice, according to AutoBild.
Interestingly, the Audi is almost as good as its competitors in everything, except infotainment and autonomous driving.
It is priced 8,000€ less than the BMW and nearly 20,000€ less than the Mercedes.
Guess which car I would choose.
