Since its introduction in 2005, the basic design of the Tata Ace has not changed much. Although the engine and a handful of features have been updated, the whole look and capabilities have remained the same. This has sparked debate if the Ace needs a major redesign. The current design's simplicity is key to its success, they argue, and it is easy to maintain and repair. But they also say that buyers trust the familiar design. But critics say the Ace is lagging behind in the areas of safety features and fuel efficiency, and driver comfort. The Ace's core functionality, they suggest, could be addressed by a more modern design that resolves these issues. The question of innovation versus reliability, brand recognition versus updating an industry standard are some of the topics the debate revolves around.
