Richard Parry-Jones is the person IMO who is responsible for creating such a great driving car.
Since Richard Parry-Jones initiated the creation of a dedicated vehicle
dynamics development team back in 1994, Ford of Europe has established itself as a benchmark OEM for steering, ride, and handling.
According to the man who oversees the 55-strong department working on
everything from Ka to Transit, little things can make a big difference.
“The key thing we’re always working toward is attention to detail,” explains Norbert Kessing, Ford of Europe’s manager of vehicle dynamics. “There are premium OEMs who can afford to put more technologies into their vehicles than we can.
Our way is to fine-tune each and every component to its limit.”
To understand why the department has had so much success, it’s worth
looking first at what it’s trying to achieve. “We’re looking for functional
harmony,” says Kessing. “It’s no good having a very agile vehicle in terms
of steering response but a very lazy reaction on the throttle pedal.
“Beyond that,
we remain convinced that customers don’t want to just
drive a vehicle, they want to have some fun doing it.
