  1. That's much closer to my experience. I expect the onboard miles per kWh figures are overestimated by a small margin, probably similar to the mpg readout optimism. Still, I don't believe we have 7kWh available for EV mode - at best that figure would includes the HV battery range as well, like Alan suggested above. The highest estimated range I've seen is something like 42.5 miles after extended periods of summer driving with no heat or air-con but I've never seen anything like that in reality - somewhere around 36 miles has been my best. However, that was enough for me to achieve my 'holy grail' in August this year after many attempts - my entire commute both ways (~65 miles) completed with a readout of 199.9mpg. If only I could get a charge point at work - then I might have a go at matching your 629mpg!
  2. Had you reset the consumption figure for that journey? I just can't square 4.3 miles per kWh with travelling 34.5 miles based on what my car tells me about my journeys. The MFD says I've been averaging 5.5 miles per kWh in the summer, and 34-35 miles has been about my limit of real EV travel. However, we all know Toyota moves in mysterious ways when it comes to reporting consumption and range figures on the MFD, so anything is possible! 😄 It will be the same for the PHV but I think there's still going to be a chunk left unused for longevity. Ancient Nerd measured 6.5kWh going in, but there's charging losses to take account of which would probably bring that below 6 in terms of actual battery charge. Add the extra for HV mode (I'd guess around 0.7kWh based on the US Prius Gen4 ordinaires with li-ion batteries) and that's still not more than 7kWh in total available to use across EV and HV. That 'feels' about right based on the distance I can travel. Even allowing for my MFD electricity consumption figures to be as overstated as the MFD mpg ones are, if the 7kWh was just for EV mode than I'd routinely be getting 36-38 miles of actual travel. However, I've actually only passed 36 miles maybe once or twice.
  3. How are you arriving at your 4.3 figure? And by 'had a range' do you mean the indicated range on startup, or actual miles travelled? I only ask because on the last occasion that I managed to squeeze out 35 miles of actual EV driving, the MFD (reset just for that journey) was suggesting I was getting over 6 miles/kWh!
  4. I thought I'd seen that 7kWh figure somewhere official, but I can't find the source now. If anything, I think that's probably overstating it. I charge from a 3-pin and don't monitor what goes in each time myself, but somewhere between 6 and 6.5kWh usable capacity would fit with the indicated average miles per kWh and actual EV miles travelled.
  5. The miles per kWh figure is on one of the MFD screens - the figure only resets when you dig into the menu and tell it to, so it will be an 'overall' since the last time it was reset.
  6. Geoff, what's your overall miles per kWh for that time?
  7. The PHV's battery capacity is 8.8kWh, but it's managed so that only 7kWh is usable. No need to worry about always topping it up, because it will never be technically 'full' anyway.
  8. It is a disappointment. However, the lamp units can be manually adjusted upwards (from the factory they're set to point at the floor about 10 yards in front of the car) and once that's done it transforms dipped beam in something actually useful, with a decent spread and reach even without any enhanced wide beam. I have cornering lights on the GS and don't really miss them when I'm in the Prius, now I've done the adjustment. The upward adjustment is necessary to make dipped beam properly usable up to 40mph, because with no 'low speed' setting the Auto High Beam function won't actually engage at all until you go over that speed. Once it's kicked in, the shuttering function is surprisingly effective in oncoming traffic although like all AHB systems it removes the ability to courtesy-dip before the approaching car actually appears around the bend or over the hill. As a result, I've taken to turning the AHB off completely, which also means I can flick onto the unshuttered, max-intensity 'high speed' main beam at whatever speed I wish. It is insanely powerful, and makes night driving on lightly-trafficked roads a joy. The reach is enough to catch on reflective surfaces like road signs fully a mile distant! I did mention the inadequate factory dipped beam height settings to Toyota UK when I was complaining about the crippled AHB system. The representative said he would 'pass on' that information. Given that the same representative also said the brochure would be changed, I doubt the facelift cars are leaving the factory with more appropriately-adjusted lamps either.
  9. Thanks for posting that excerpt. I am disappointed but not remotely surprised that Toyota UK have changed precisely nothing in that to reflect reality - it is identical to the pre-facelift brochure and points 1 and 4 are completely wrong. There is no low-speed mode on UK cars, nor do the lights steer around corners at all. I doubt they've actually changed the cars themselves, so I suspect that page is as misleading as it was for the pre-facelift PHV. I guess we'll have to wait until someone buys a facelift PHV to test the lights' operation!
  10. I just use the 3-pin and charge every night, which works for me as the car is only really used for commuting. I think it takes around 3 hours for a full charge this way. Even with a wall box it will take around 2 hours as the car can't do proper fast-charging, so it didn't seem worth the investment to me.
  11. Does it describe the adaptive headlights as steering the beam around corners, or operating a wide beam at low speed?
  12. Do you have a copy? It's still missing online. I would be very interested to know if they have updated it so it actually tells the truth about the adaptive headlights, as Toyota UK suggested to me they would be updating it to reflect how these actually operate on UK cars. Also, the auto pre-heating function should now no longer be included as that isn't fitted to UK cars either. Unless, of course, they've changed the spec for the 2019 version.
  13. Fair enough. Everyone has different experiences. Let me share some more detail on why I will never buy Goodyear again myself. On my Gen3, I went from from 17" wheels on Michelin Primacy to 15" on Goodyear EfficientGrip Performance. Running both at my usual 39psi, fuel economy was immediately noticeably worse by around 5mpg, despite the reduction in size. This failed to improve after scrubbing in - I could only get close to the mileage I was getting on the 17" Michelins if I pushed them all the way up to 45psi which had the added benefit of improving the awful jelly-like handling. I am one of the least 'sporty' drivers on the road these days and actively dislike fast cornering, but I still found the Goodyears to be unbearably imprecise at standard pressures. As time went on, I wasn't comfortable with running pressures so much higher than recommended, so I dropped back to 40 as a compromise. I can state categorically that those tyres did not get quieter with extra wear, and after 20,000 miles the fronts were worn down on the outside edges (despite the overinflation) which was absolutely appalling given how gently I drive. By comparison, the Michelins had gone past 60k. That wasn't enough to put me off Goodyear completely, though. I subsequently put 17" Goodyear F1 Asymmetric 3s on my wife's Auris hybrid, again replacing Michelin Primacy. They actually delivered only slightly worse economy, similar cabin noise and similar comfort and although they woollied up the handling a bit that wasn't a concern. I actually thought they were decent tyres at first. However, the sidewalls proved to be horrendous and, in my view, a serious danger. Over two years, two of the four needed replacement because they'd developed bulges. Then, when my wife hit a pothole with the offside front, the sidewall actually tore straight through so the whole tyre ripped completely off the rim. Fortunately she managed to retain control and no serious damage was done to anyone. However, I was shocked at how the entire tyre had simply disintegrated just from hitting a hole in the road. Unfortunately, during that initial period when I'd thought the F1s were decent, I'd decided to fit a set of Asymmetric 2s to my GS. Perhaps because of the lower-profile 18" size, the sidewalls weren't so much of a problem. The issue instead was a catastrophic reduction in fuel economy, despite replacing similarly E-rated Bridgestones. I lost a full 10mpg, which translated into somewhere around £5-7 per week. I finally got shot of the things as they'd worn out after two years and a mere 30,000 miles. However, I worked out that I'd lost so much money in fuel over that time it would actually have been cheaper to throw them in the bin immediately after purchase! I'm sticking to Michelin from now on. The OE Primacies on the Auris and Gen3 were fantastic tyres for both economy and wear, and weren't any noisier than the Goodyears I replaced them with on either car. I've put CrossClimates on the GS, which has returned economy to more reasonable levels.
  14. I don't think that sound suppression system is available in tyre sizes appropriate for the Prius. Continental do something similar as well, but again not available in our sizes. In any case, I will never buy Goodyear again after being repeatedly suckered in by their own hype and by positive reviews elsewhere, only to find they offer terrible economy, horrible soft sidewalls and dreadful life. In fairness, neither the Efficientgrip Performance nor Eagle F1s that I have fitted to recent cars have been any worse for noise than the tyres they replaced, but they weren't any better, either.
  15. It's not pointless if you suffer from tinnitus (as a surprisingly large proportion of this forum appear to), because excessive continual roar can be a real impediment to the enjoyment of a vehicle. It's also not pointless when one of the greatest assets of our hybrid cars is that for a significant proportion of the time, they don't use a series of controlled explosions to propel themselves. Addressing road noise then becomes far more important than it would be when you've got a raucous diesel tractoring away up front.
