Can someone explain why its not simply a matter of combining the outputs?
If you can find a power output graph of a hybrid car you’ll see that the lines are totally different for the combustion engine and electric motor. As far as I know (and I could easily be wrong) it’s a matter of finding the points where the maps match to create the new peak power and torque.
… Makes more sense on the graph’s.
Generally the electric motor and petrol motor reach peak power/torque at different revs, or the motor is designed to fill out weak spots in the engines power band. It also depends on the battery charge, vehicle speed etc. For example a Gen 2 Prius used to output 400nm of torque from about 10-40km/h if the battery charge was about 60%, but getting a reliable number on a dyno is near impossible, hence why Toyota doesn’t quote torque figures for its hybrids.
Wow, they have put the battery in the boot… Fail.
Where is the Greens and Labor on this! why no Tax reduction for going Hybrid its all BS!! lets get back into V8′s
Thanks Tom and Alexander for the explanation.
Jez, I suggest you pop over to the CA article(s) on the “2012 BMW 5 series range updated”.
A 0-100km\h time of 5.9 secs does not give this Hybrid5 the third fastest rank in the range. 5.9 secs is the same as the updated 535i and SLOWER than the 535D which is now 5.5 secs (previously 5.7).
How come manufacturers dont go with turbo diesel electrice hybrids? Wouldnt it be even better since a turbo diesel engine alone provide excellent fuel consumption…so attaching a hybrid motor surely would make it more efficient???
It would be near ideal – problem is diesels are more expensive than petrols, and hybrids are more expensive than petrols. Combine the two and they’d be too expensive to compete.
Oh…..i thought it was something more technical to it…like maybe diesel engines not compatible with electric motors or something. i didnt think cost could be an issue…
Peugeot’s got it up and running. The trouble for many years, developmentally, has (perhaps among other things) been the thumpy shutdown and startup behaviour of diesels, I think. Nowhere near as smooth as petrol, and that presents a refinement challenge for likely buyers. Diesel Passats with the stop-start tech apparently suffer from this a little. I’m well open for correction.
Good tech, and I dig the wheels and the colour of the car in the pics.
the outputs arrive at different rpms for each motor. so each can’t be putting out their max output at the same time
