Stop-Start to Be in 8 Million Vehicles by 2017

New study predicts major savings in fuel bills.

by on Aug.13, 2012

Ford will offer stop-start as a $295 option on the 2013 Fusion.

You come to a stoplight and press the brake pedal and the car suddenly seems surprisingly quiet.  As the light turns green and you move your foot back to the throttle you hear a brief rumble from under the hood and pull forward as if nothing had happened.  That’s because the vehicle’s stop-start system worked as it was supposed to, briefly powering down your engine instead of idling in order to save gas.

The technology first appeared on the original Honda Insight and Toyota Prius hybrids, a dozen years ago, and is now a standard feature on the growing number of gas-electric vehicles offered in the U.S. market. But a number of manufacturers are starting to add the fuel-saving technology to their more conventional car, truck and crossover lines.

In fact, a new study by the Lux Research estimates stop-start will be offered on as many as 8 million vehicles sold in the U.S. by 2017 – and some forecasters believe it will be even more common in Europe and Japan, where fuel costs justify the technology’s modest price premium.


Ford to use TRW Electric Power Steering in Europe

Fuel saving technology is migrating from North America.

Energy consumption of an EPS system is less than seven percent of a conventional hydraulic power steering system.

TRW Automotive Holdings Corp. (NYSE:TRW) today announced that it is debuting a larger version of its Electrically Assisted Steering (EAS) system in Europe for the first time with Ford Motor Company later this year.

Ford has been using the fuel-saving steering gear in North America for the past two years on Taurus, Fusion, Flex and Mercury Milan models, as well as Lincoln MKS and some MKTs.

TRW also confirmed that a second major global automotive manufacturer would use this Belt Drive – also called Rack Drive – Electrically Powered Steering (EPS) on mid-size passenger cars beginning in 2012. The Belt Drive system only consumes power when steering assist is needed.

The energy consumption of an EPS system is typically less than seven percent of a conventional hydraulic rack and pinion power steering system. This equates to a fuel savings of 0.3 to 0.4 L/100 km, with a corresponding reduction in carbon dioxide emissions of approximately 7-8g/km (up to 3.5%).


The Belt Drive EPS system supports rack loads of up to 15 kN or higher depending on vehicle kinematics and dynamic requirements. Column Drive systems are typically used on systems with output levels up to 85-100 Nm.
