  1. That does happen, but I'm talking about a situation when you're going downhill with zero throttle. Once the SOC is at the high state it should just stop generation and use engine braking - I find it hard to believe there is anywhere for electric energy to be used in this state where there's enough momentum (assuming you're trying to slow down). Maybe after the descent it will try using more battery, but not during. It's hard for me to replicate with the Plug-in, and maybe the 2nd gen is different anyway. MG1 is nearly always spinning when the ICE is running, sometimes backwards :) But the wheels are primarily rotating the ICE in this situation.
  2. There are various explanations of how engine braking works in the Prius online, including what it does in this situation of extended downhill driving. I can't find anything official, but this describes the main modes of operation: But it makes no sense for it to waste energy from the battery anyway - it would be inefficient and unnecessary. Once the SOC gets to a certain high level it will just stop regeneration from MG2 and use the ICE instead to create resistance - it may be wasting kinetic energy to slow down the car, but no electric energy is being used from the traction battery. The momentum of the car is turning the ICE. Readouts from an OBD-II scanner during this mode will tell you what's really going on.
  3. Maybe I'm misunderstanding, but this is not a mode of operation that happens with the Prius. MG1 will only use electric power to start the ICE, or MG1 will be driven by the ICE to generate power - it will never "burn electricity". There is no such mode where it will waste energy from the battery. If you select B mode, or if you're going downhill when the traction battery reaches a high state of charge, the transmission will apply engine braking using the ICE - essentially just like engine braking with any normal ICE car. Due to the way the transmission works, MG1 and MG2 are always going to be rotating in some fashion anyway.
  4. It's just engine braking - there is no consumption of fuel (no spark), you're just using the resistance of the ICE to slow the car down. It will do this if the battery is fully charged and you're not applying any throttle, as it can't do any regen in this state. As to why it doesn't stop afterwards, I don't know. Maybe you're not waiting long enough for it to go back into its normal state? Or is it automatically shifting into B mode or something weird?
  5. The Prius C is sold as the Aqua in Japan, and was a best-seller there for a few years. It's a bit bigger than the Yaris, and competes directly with the Honda Fit/Jazz and Nissan Note over there. It does seem to have the same powertrain as the Yaris Hybrid, which is a slightly updated beltless version of the 1NZ-FXE from the 2nd gen Prius. The Yaris Hybrid seems to be a Europe-only, possibly because it's built in France (not sure)?
  6. The clock on the Gen 3 is integrated into the MFD, it's not a separate device.
  7. Yes, mine's not great - I don't know how quickly it goes off but I've had to adjust it several times in the year I've had the car.
  8. The OBDLink LX is Bluetooth. There is only a wifi version of the MX, which is more expensive again. I got a Belkin dash/windscreen mount from Halfords, and mounted it on the quarter light in the A-pillar in my Prius. Seems OK, a bit wobbly when going over rough roads.
  9. Yeah I use an OBDLink LX, which is what they recommend (I already had one). Not the cheapest scanner by any means but it's reliable, has a 3 year warranty, and is faster than the cheap stuff. Still hesitant to leave it plugged in though...
  10. There is some documentation here: I tried it on a longer journey yesterday, but unfortunately the battery went on my phone right at the end of my journey and it failed to save the data :( Will have to try it again...
  11. I didn't know about that Hybrid Assistant app, tried it out yesterday and it's quite useful - lots of data straight out of the box (unlike something like Torque where you have to create the screens from scratch). The Hybrid Reporter app is also very interesting, although maybe too much information :)
  12. I didn't know there was a touch up kit for pearlescent paint. I have a 2012 Plug-in in white pearl and also have a few scratches and stone chips I'd like to sort out - looks like a previous owner tried to correct some but did a crap job, like they used plain white paint or something. Not sure exactly what you're saying about this "Gen 3" stuff but any wax or sealant need to be completely removed before doing any touch-up work.
  13. Why would that put you off a PHEV? You only have to charge when it suits you. I guess if you couldn't charge regularly from home or work then it probably doesn't make much sense.
  14. OK, I'm not familiar with UK terminology. "Fast" here means anything >23kW, and we don't use the term "rapid".
  15. The 1st gen PIP is limited to 10A, so 10A @ 230 V means a maximum of about 2.1 kW. Or did you mean the max charging capacity is 3.3 kWh? The new model only has a 3.3 kW charger AFAIK. That blog post about the free charger offer only mentions upgrading to a 32A installation for "future proofing", so I suspect the Prius can't avail of this - having a 32A charger would make a lot more sense if you switched to a BEV, especially as capacities are increasing over 30 kWh. I assume if you use a granny cable on the new Prius it would still be limited to 10A, as no one seems to trust sustained loads of 13A on domestic sockets. Using a Type 2 cable is not about fast charging (I wouldn't call 16A "fast" :) ) - it's just the European standard for AC charging. Pretty much all other cars have them now (except older models like the Leaf). Not sure about the UK, but all public AC charging points (standard and fast) are Type 2 here. CCS and ChaDeMo are used for fast DC charging.
