The diesel 308 Hybrid HDi.
Peugeot will use the Frankfurt Motor Show for the world premiere of its new 308 Hybrid HDi, a diesel hybrid which emits 80g/km of CO2 and reduces fuel consumption by 58% in the NEDC Urban Drive Cycle compared to a standard 308 HDi.
The new 308 Hybrid HDi demonstrator represents another step on the path towards the planned commercialization of the technology in 2010. Further evaluation of the original Peugeot 307 Hybrid HDi demonstrator in 2006 (earlier post) has confirmed the choice of a diesel engine, instead of a gasoline engine, as the best option to provide the best reduction in fuel consumption and emissions, according to Peugeot.
The demonstrator’s parallel hybrid powerplant uses an 80 kW (107 hp) 1.6 HDi DPFS diesel engine coupled with a 16 kW (continuous) electric motor providing a maximum power output of 96 kW (129 hp)—comparable to that of the 308 with the 2.0 liter HDi DPFS 100 kW (134 hp) diesel engine—and a 6-speed electronically controlled manual gearbox. A 200V, 5.5 Ah NiMH battery pack provides energy storage, and is recharged via regenerative braking.
General dynamic performance is comparable to a standard 308 HDi. In-gear acceleration, however, both in town and on the open road, is improved with the Hybrid HDi. During in-gear acceleration, the diesel engine is backed up by the electric motor which is able on demand to deliver a power boost of up to 23 kW and 130 Nm (96 lb-ft) or torque.
Fuel consumption in the combined cycle is 3.4 l/100km (69 mpg US) and CO2 emissions are 90 g/km—reductions of 38% compared to an equivalent 308 diesel HDi model.
The engine has been designed to meet the future Euro 5 emissions requirements coming into force in 2009. The 308 Hybrid HDi offers an all-electric range for journeys in regulated urban centers. The vehicle’s aerodynamic profile and use of Michelin Energy Saver low rolling resistance tires further enhance its performance.
Compared to the previous 307 Hybrid HDi demonstrator presented in 2006, the focus of the development has now switched to concentrating on the packaging of the hybrid technology into the structure of the new 308, and to ensure its compatibility with the future Euro 5 emission standards.
To ensure a competitive purchase price, priority has been given to using as many components as possible from current Peugeot vehicles. This has enabled the number of specific parts associated with the hybridization of the 308 to be reduced by around 30% compared to the previous 307 Hybrid HDi demonstrator.
The vehicle is started by a customary ignition key but, unlike a conventional vehicle, this does not start the diesel engine. The electric motor alone is responsible for starting and driving at low speed, while only the diesel engine is used on open roads and highways, with both units coming into play simultaneously to provide quicker acceleration. The system is fitted with a 6-speed electronically controlled manual gearbox able to operate in automatic or manual sequential mode.
A special button provides access to an all-electric “ZEV” Zero Emission Vehicle mode. Operation of the diesel engine is then restricted to more pronounced acceleration phases or high speed driving.
All the powertrain operating modes are controlled by a Power Train Management Unit (PTMU) according to the driver’s requirements.
The driver is informed in real time of the powertrain operating mode by a schematic diagram on the vehicle’s colour multifunction display. Other information is also available, such as the battery charge status or the power train operation mode.

Rest In Peace, old friend, your work is finished.......
If you want on or off the DIESEL ”KnOcK” LIST just FReepmail me........
This is a fairly HIGH VOLUME ping list on some days......
KnOcK!...............
I can’t wait to get me one of the new ‘euro style diesels. Oceans of torque, sub 7 0-60, and 40+ mpg. Sign me up! Shame though that so many Americans are prejudiced against diesel thanks to the horrific engines GM foisted on them a generation ago.
The battery and motor specified will only run 4 minutes on a charge. Maybe that’s the ticket- most power is used during acceleration which only takes a couple of minutes, so keeping the weight down makes sense.
Watch the fuel prices go up as MPG goes up. Fuel suppliers are not going to allow their profits to go down. You may use less fuel, but you will be paying the same total amount each and every week. The people that are really going to be hurt are the ones that cannot afford these vehicles.
Jaques Le Frebre of Peugeot sayys, " See how our new diesel hybrid does not burn as harshly when lit ablaze but muslim students."
Thankfully, most young people do not remember those monstrosities!..............
LOL!!!...
The market forces control the price. If it were simply up to dealers we’d be paying $20+ per gallon now.......
Makes sense. Diesels traditionally have slower acceleration, so a powerful boost from an electric motor will help alleviate that symptom......as well as mitigate the greater fuel consumption required at the standing start...........
Caller to a Raleigh, NC talk show several years ago - responding to the question: “What are the two biggest mistakes you ever made?”
“I sold the family farm and bought my wife a Puegeot.”
“Shame though that so many Americans are prejudiced against diesel thanks to the horrific engines GM foisted on them a generation ago.”
For me it was the Mercedes Diesel engines. They spewed black smoke and were noisy.
Peugeot is not interested in the USA market and I’m not interested in buying a Peugeot. Back when they were selling here I looked at them and decided that I didn’t like what I saw. I know of some who made the mistake of buying one.
Yeah, but if it’s successful in Europe the other automakers, including the ones who sell to North America, will develop similar products. Competition is always good.
I drive one of those every day. It doesn't smoke as bad now, because of the new diesel fuel.
The thing is: I'm still driving it today. How many other cars of that era are still running?
My Buddy had a brand new Peugeot once. After the ten trips to the shop for electrical problems and having the blown engine replaced it spontaneously combusted one night in his driveway.
Must have been built by a muslim..........on a Friday.....
If it is not a plug-in hybrid it will be obsolete by the time it is introduced.
I would also suggest the diesel engine and drive train be replaced by a diesel generator that is set to run at its most efficient RPMs. The generator then supplies the electricity to the electric motor and recharges the batteries. Kind of silly to have an electric and a mechanical drive train. Why not just use the electric?
Battery technology is not yet (though very very close) advanced for total electric only. It (any hybrid) is just a bridge to total electric.......
