The infamous R-class from the Mercedes stable received a massive blow last week when a top Mercedes official admitted that the car didn’t live up to their original plan. But Mercedes didn’t spend much time mourning and is planning a replacement already, with the hope of topping the popularity charts. Low car sales would probably motivate the new R-class to a be more aggressive wagon and quite different from the current one. The only question remaining is whether it would be able to drive its way into the hearts and garages of customers especially with tough competition coming from BMW X6 crossover.
