While Ford sacrificed the V6 entry-level engine for the 2018 facelift of the Mustang series, the improvements for the other two powerplants – the EcoBoost and V8 GT – are worthwhile, coming with increased power, and we find out now also more efficient.
Fuel economy for the US version – we’ll have to wait and see what changes have been brought to the international one – has gone up by as much as 5.6 percent, and aerodynamic tweaks have also been operated to improve handling. Ford engineers Jonathan Gesek and Mike Del Zio are now part of the story behind the improvements brought by the 2018 model year update, with the company recognizing the importance of “human touch” even in the data-driven, computer-monitored world of vehicle testing. Del Zio, a vehicle dynamics engineer – the objective one – reported that wind tunnel data doesn’t account for the real-world feeling. Gesek, an aerodynamics engineer, and the subjective part of the equation had a quick fix… he “applied a simple strip of duct tape over the lower gap of the grille” to tamper with what is known as front-end lift.
The result led to the fine tuning of the car’s handling and a modified grille ending on the final product. They were both implicated in the testing procedures over the years for the Mustang, and were part of the team that led to better aerodynamics and increased overall efficiency. The changes reflect in up to 3 percent lower drag on the EcoBoost model, and improved performance across the board. The EcoBoost’s EPA-estimated fuel economy ratings have improved by 4.2 percent combined while the GT V8 with the new automatic has gone up by 5.6 percent.
