How Ford designers used a specialized suit to simulate aging for better car ergonomics.

In short: To improve the design of the third-generation Ford Focus, engineers employed a unique Third Age Suit. By restricting their own movement and physical range, designers could directly experience the limitations of elderly drivers, leading to ergonomic insights that were integrated into the vehicle's final cabin and control layout.

The third-generation Ford Focus, or Focus Mk III, represented a pivotal shift in strategy under CEO Alan Mulally’s "One Ford" plan. Launched in 2011, the project aimed to unify global resources to create competitive vehicles sold across international markets with minimal regional changes. This global ambition required a design that appealed to diverse demographics, including an aging population, prompting the use of the Third Age Suit to simulate physical constraints during the development phase.

Beyond ergonomics, the vehicle introduced significant technical changes, including a new 2.0-litre direct-injection engine and a redesigned cabin. However, the model faced substantial scrutiny regarding its DPS6 PowerShift transmission. Many owners reported persistent shuddering, which Ford attributed to dry-type clutches. While the company issued software updates and clutch pack revisions, the issue sparked numerous lemon law claims. Ford maintained that the transmission’s behavior was distinct from traditional torque converters, sharing characteristics with manual gearboxes.

The vehicle's history is also marked by significant safety and quality recalls. In 2017, Ford recalled models equipped with 1.6-litre EcoBoost engines due to a lack of coolant circulation that could lead to engine fires, a move that resulted in a US$300 million charge. Despite these mechanical challenges, the Focus achieved global success, becoming the world's best-selling car in 2012. The platform itself was engineered to be 25% stronger than its North American predecessor, showcasing the tension between Ford’s ambitious global design goals and the complex reality of mass-market manufacturing.

The car's production footprint was vast, spanning facilities from Saarlouis, Germany, to Chongqing, China. Regional variations were common; for instance, the Japanese market received a model that exceeded local compact car tax width dimensions, while the North American market saw the introduction of the SFE package to boost fuel economy. These regional adaptations, combined with the iterative updates to infotainment and trim levels, highlight the complexity of managing a truly global automotive platform.
