diesel hybrid

[5lab]

did a quick search and couldn't find anything, but have we talked about this yet

it's not the most 'ph' car, granted, but surely this is going to be the powertrain to have in shopping cars for the next 10 years or so (ie until electric\hydrogen really takes hold)? in that big, ugly 4wd beast it puts out 200bhp and does <100 co2's - I'd be surprised if they didn't put the same drivetrain into the arsey zed - a bit more map to the diesel engine and you could have a (say) 220 bhp coupe with free road tax and very favourable BIK tax for cc drivers.

What a brill idea. Wonder if it's got wheel motors or a traditional diff?

I'd have one if it wasn't a pugeot

[5lab]

looks like some kinda diff built into the rear motor (from that picture)

For sure, its not the best car to launch it on but its gotta be counted as a good thing right? as has been said, not very PH but its prolonging the worlds oil supply. It also offers a chance for PHers who dont want to be seen in a Prius, to drop their BIK rate.

never really understood why hybrids have so far been petrol, and not diesel. Is this due to the markets that they are aimed at?

Partly, also due to petrol being "cleaner" in terms of emmisions tha affect air quality (rather than just co2) so arguably better in the cities where hybrids tend to get used.

I dont know and havn't read it anywhere, but could it be something to do with the higher torque of a diesel and the electric motors and generators not being sturdy enough til now?

Cost of both systems makes the car even more, a petrol engine ie far simpler than common-rail derv. The target markets have previously been US and Japan, non big diesel users. All the bits for derv and hybrid add massive material cost, hence the Peugeot is going for old school NiMH. Premium brands with be a Lithium chemistry.

France with the diesel costs and then the way French buy french regardless of the product will probably mean this is not a risky product for them to try out.

Electric generators are not mechanically linked in how they take power from the system, so the torque has nothing to with anything. In this application you can see the type of fuel it runs on has nothing to do with the rear electric axle. Only problem is that your motor is fixed ratio and not geared as an engine assist. Peugeot essentially have a standard car front end though which again cuts the cost as that engine is used in everything.

yes, and as nsmith said, the diesel engine requires a hefty battery to turn it over- high compression et al, and partly because the hydrids biggest market is the US. Where you just dont get Diesle cars. Trucks and ;rigs yes. But not really cars and SUV's

Interestingly Mercdedes has developed their own Diesel hybrids.

So have GM, there was talk of the 1.3 CDTi in the Ampera, cant remember what engine is going in it now.

Its the 1.4, twinport, i think for the Volt. Again petrol carry over stock parts.

Petrol run at constant speed should be decent to compare to an iron blocked diesel and wont require all the aftermarket treatment so it will be lighter. Constant speed allows alot more options with powertrain technologies and tuning NVH.
