Peugeot e-HDi: Defining Characteristics

SYDNEY – July 4, 2011: In 2004 Peugeot Citroen Group (PSA) pioneered a micro-hybrid stop & start starter-alternator technology. Over the following thirty six months more than 30 patents were filed and a total investment of 3 million EUROS was made with nearly 500 PSA technicians and engineers involved. Peugeot has been extremely proactive in taking up the environmental challenge and intends going even further, reaching several key milestones for sustainable mobility – along the way producing a brand-defining initiative.

In 2009 Jean-Marc Gales, Executive Vice President, Brands, and Christian Chapelle, Director of Powertrain and Chassis Engineering, presented the world premiere of e-HDi, a new generation STOP & START system which combines a reversible starter-alternator with a diesel engine. STOP & START technology turns off a car’s engine whenever the car is at rest - for example at a stop light or in a traffic jam, and then restarts it instantaneously as needed.

This latest innovation, which delivers improvements of up to 15% in an HDi engine’s fuel efficiency and CO2 emissions, will be deployed on the Peugeot 508 and 308 series II from Q4, 2011 in Australia.

The e-HDi system’s unrivalled performance reflects the forward-looking combination of several technologies:

A 1.6ltr HDi EURO 5 compliant diesel engine delivering 82kW of power at 3600 rpm and 270 Nm of torque at 1750 rpm - one of Peugeot’s most efficient powerplants.

A STOP & START system with a second-generation reversible starter-alternator (i-STARS - Starter Alternator Reversible System supplied by Valeo).

An e-booster system, for instantaneous engine restart.

An electronic alternator management system, for regenerative braking.

A gearbox with optimised gear ratios.

In addition, all e-HDi-powered models can be fitted with ultra-low rolling resistance tyres to further augment the fuel economy and reduce emissions.
