At its Innovation Day in Paris—at which the company described its Air Hybrid technology and rollout plans (earlier post)—PSA Peugeot Citroën aso showcased a next-generation mild-hybrid technology that significantly reduces fuel consumption, by 10% to 15% for an equivalent engine, and CO2, by 15 g/km, compared with its e-HDi technology.
The Group’s Eco Hybrid system is compatible with gasoline and diesel engines and will be fitted on its vehicles starting in 2017.
The system combines a 10 kW electric motor with a 48V Li-ion battery. The electric motor can drive the vehicle alone at speeds of less than 20 km/h (12 mph)—for example, when parking or leaving a car park—and supply additional power under acceleration. This solution is compatible with gasoline and diesel engines mated with manual or automatic gearboxes.
The rationale behind the development is to offer customers a vehicle that consumes significantly less fuel through the development of a technology that is accessible to the greatest number due to a lower cost.
The system is suited to segment B, C and D vehicles.
PSA says that the Eco Hybrid is a natural development of its e-HDi technology for customers. The technology is a co-development with suppliers Valeo, Bosch and Continental.
This will be very good if they can roll it out across the range at minimal extra cost.
It will reduce pollution and noise in cities, as well as save fuel.
It all sounds quite feasible, lets hope they implement it.

Also, it is interesting to see a company which was a stalwart of diesel moving to mild (and air) hybridisation.
I suppose it(hybridisation) is the best way of improving economy in the city, and if it does not add too much to the cost of a diesel engine, it can be sold at a profit and in large numbers.

Another use of Li-ion cells, though just 10 kw(~13.3 hp) seems small for the extra cost.

So it is a hybrid without plug-in, first gear (max 20 km/h) electric drive and very small battery. That is less than Toyota Prius did 15 years ago.
To me this is too little. What we need is hybrid cars, that at least can drive electric for most of city driving.

Sounds like the GM E-drive. By then GM should have made E-Drive a universal feature on all its cars, at the rate they are doing so.

Seems unexciting and minimalistic.
And not until 2017.
But quite likely the best use of batteries until battery costs go down and performance improves.
I wonder if a small, low energy, low cost capacitor system, keyed toward providing a significant level of "free" extra, short term thrust for acceleration after each stop, would provide more driver satisfaction than the typical low power, mild hybrid.
It would capitalize on the higher POWER recovery and delivery of capacitors compared to batteries.

P.S.
Not to imply this is in any way, a new idea.
