Throwback Thursday - Ford’s electronic tech test bed, 4 September 1985 ~ All About Ford Mustang

Ford made a real effort to develop a reputation for design technology in the 1980s, and the Eltec was one of the outcomes

During the 1980s Ford made a big effort to throw off its reputation for producing solid and reliable but hardly innovative cars and increase its focus on design and technology.

Out of that strategy came the Eltec, or ‘Electronic Technology’, an advanced prototype car that pointed to the way in which the company’s top designers and engineers perceived the car of the 1990s.The Eltec was a collaboration between Ford’s R&D departments in Dunton and Cologne, plus the Ghia Design Studio in Turin. It was made to “prove that even small family cars can benefit from electronic co-ordination of all their functions and that electronics can improve a car’s dynamics while reducing fuel economy and exhaust emissions”.

Built in less than 18 months for a Frankfurt show debut, the Eltec was bristling with ideas, as Autocar’s then technical editor Graham Jones described when he examined the car.“The body is a small, four-door hatchback configuration featuring a large glasshouse, a slippery shape and specially designed headlamps,” he wrote. “A glass sunroof comprised five louvres that could be either opened for ventilation or electrically retracted.

“The suspension is of the active ride variety, with its own electronic brain to control spring rates and ride height. The central black box also controls electronic anti-lock brake and anti-wheelspin systems, while the dedicated wheel/tyre combination is of the run-flat type.”The engine and its control system were the stand-out features, presaging today’s trend for frugal downsized units.

“The 1.3-litre unit is brand new and develops 80bhp at 5000rpm and 88lb ft between 2500 and 4000rpm,” wrote Jones. “Designed and built as part of Ford’s lean-burn engine technology programme, the aims were to produce a power unit with compact dimensions, low internal friction and the ability to pull well from low engine speeds at the same time as producing good performance through the speed range.

“The engine is mated to Ford’s CTX continuously variable transmission, using the familiar belt and pulley drive arrangement. Next to the gear lever is a smaller lever which allows the Eltec driver to select either ‘Power’ or ‘Economy’ modes. In the latter, the transmission ratio is controlled so that engine speed is at its most efficient.

“What makes these developments significant is that they are integrated using a modified version of the EEC-IV computer fitted to the 2.0 EFi Granada and Sierra. Unlike conventional cars with onboard computers, which control the engine and transmission as separate entities, in the Eltec the computer regards them as one system.

“The computer not only matches the operation of the engine and CVT to the demands of the throttle pedal but also continuously fine-tunes the engine to provide the best possible fuel consumption. In short, Eltec could herald the age when an engine holds perfect tune permanently.”

While Ford’s top brass emphasised that the Eltec didn’t preview a specific production model, Autocar’s man wasn’t altogether convinced, and noted that “a brand-new Escort is due in 1991”.
