  1. Maybe so, but the discussion on page 2 was about 225/45R17 in which you certainly can get both. On my Honda, which was on 225/45r17. I went from eagle f1 asymmetric to pirelli cinturato p7 and certainly noticed the much greater compliance in the Pirelli. The point I was trying to make was that the eagle F1s on Adrian300h's (where he does report skipping) are less compliant than the Yokohama blueearth on wharfhouse's car (who does not report skipping). All else being equal (car, tyre size).
  2. Agreed, I had huge problems with RainX smearing on the windscreen, especially in colder temperatures. I've moved to Gtechniq G5 for side windows and mirrors - better than rainX and lasts WAY longer. However, it takes a lot of buffing off. Car looks great Rayaans. Definitely looking forward to giving our GS a good going over when we get it!
  3. Does anyone else enjoy and/or take great pride in some specific little detail on your vehicle, and making it really stand out? I'll give an example, the D5 & Polestar badging on my V70: So often with this type badging you see dirt inside the lettering because people just run a sponge (eurgh) or mitt over the top of the badge, and don't properly get in and clean it. Badging is often just avoided, with no attempt to make the chrome pop after washing, even if people are giving the car a polish or wax. Sometimes I think people debadge rather than deal with detailing them. Similarly, the very deep Volvo lettering: So what are your proud little detailing details?

    Second Car

    A little research into the UK car market would have made this spam distinctly more convincing...
  5. They're among the softest of UHP tyres, sure, but distinctly stiff compared to a touring tyre with a thin sidewall and balloon profile (eg p7 cinturato). That was my point, rather than the f1 being the stiffest.
  6. Just to echo others, this is a common thing - as someone else posted earlier, mercedes have got it so bad with their GLC that there's a class-action lawsuit against them for it (from what I've read, it afflicts RHD cars much worse, because of a change in the steering geometry that occured during the changeover. Like it's GLK predecessor, the GLC seems not to have RHD in mind at the design stage, as there's nowhere for your left foot to go in an RHD GLC). Our V70 also does this on very tight turns. Two posters in this thread compared notes on 17" IS wheels - The eagle F1 Asymmetric have very stiff sidewalls while the Yokohama blueearth do not. It's not only the profile height, but the overall stiffness of the sidewall. That's why merc's fix for the GLC was to fit winter tyres - softer, more compliant rubber. Ultimately it's about choosing an appropriate tyre - there's a lot of people who "big up" tyres like the F1 Asymmetric, Michelin PS2, etc, but these are stiff UHP tyres that are aimed at cars where sporting responses are the #1 priority - eg BMW Z4, Toyota GT86, Supra, Cayman, etc. They're not really appropriate on a luxury saloon or family car - for this you're better off with a more compliant tyre like EfficientGrip, Crossclimate, Primacy, Turanza, etc (although I do NOT recommend Pirelli P7 Cinturato - we suffered a very high failure rate of these tyres). No, they won't provide quite as much grip in warm conditions as a UHP tyre nor as sharp response, but they have a wider operating envelope, lower noise, better wear and less crabbing. I recall a thread on the Volvo owner's club where someone was utterly insistent that Pilot Sport Cup 2s were the best tyre for a 2.0 diesel V50...
  7. Holy Thread revival! I've not owned many cars... 1998R Mitsubishi Galant GLS 2.0 Auto Estate 2001X Mitsubishi Galant Elegance GDI 2.4 Manual Estate 2003 53 Honda Accord Tourer Executive 2.0 i-VTEC Manual 2011 Volvo V70 D5 SE Lux Polestar Geartronic 2015 Nissan Leaf Tekna Now the 2015 GS450h Premier is coming in to replace the V70 and will reside alongside the Leaf. As you can tell, I've always had a bit of thing for Japanese cars. I hate the spec stinginess of european cars, gouging for things that should just be standard - One time I had a VW Passat B6 hire car - R-line bodykit, Alloys, parking sensors, 2.0TDI with DSG gearbox..... and wind-up windows in the back!!! So of my 5 cars there's one worst and 4 best... The worst was the Galant GDI - it was a mistake to buy and I only kept it a year. Everything was on the verge of collapse with that car, and it was a shame because my previous Galant was great. The GDI engines were a nightmare outside of Japan, the gearbox was awful, suspension was dying (in worse shape with half the mileage than my previous), etc. The other 4 are all the best cars I've ever had, in their own ways. My R-Reg Galant was my first car and so it holds a special place for that. It had its mechanical foibles but it never let me down. Mitsubishi were an underappreciated brand I think, and back in the 90s they were doing some great engineering - sadly it all rusted away far too quickly. My Honda was great - great engine, amazing gearbox (rifle-bolt precise, never mis-shifted, never reluctant to go into gear), bombproof mechanicals and it was incredibly cheap to run as I could DIY service it. The Volvo is a great car because it's extremely comfortable with lovely seats and ride. The interior design and quality of materials is much nicer than the 5-series and E-class, and there's a lot of things where you feel that Volvo actually design cars to live with, rather than for the motoring press. The Leaf is great because being EV it's so zippy and responsive, even on very basic mechanicals (macstrut/torsion beam). Interior is pretty naff and the infotainment relatively infuriating, but the EV side is so good that it makes up for it. It's like my Canon EOS D30 was - very early digital SLR camera. The focusing, metering, framerate, viewfinder, etc were all awful - it was a terrible Camera compared to my EOS 3, but it immediately demonstrated the crushing superiority of digital to film (And I never felt that I had a camera that matched the EOS 3 as a camera until many years later with the 5D3). In a similar way, the leaf is not a very good car compared to what I'm used to (first thing I've ever owned without independent rear suspension for example), but it demonstrates the crushing superiority of EV over ICE.

    Jaguar I pace

    I've only seen once I-pace. I like the exterior of the car, but I find the interior is a bit bland - sadly the whole jag range suffers this at the moment (except for the venerable XJ). The XF, XE, F-pace interiors are all very "meh" to me. To me the best interiors in the mid-range marketplace at the moment are the new-generation Volvos and by quite a long shot the Tesla model 3 (you have to sit in it to get the experience of it - the openness of the (standard) totally panoramic roof, the low windscreen view forward, the brilliance of the UI). However, I will commend Jaguar for taking the EV bull by the horns. It's not very efficient compared to a Tesla, and the current provision of CCS charging isn't great, but that will change. At least they have done something (and in contrast to the shutdown of UK plants building the diesel models, JLR have now increased production of the I-pace at magna steyr in austria because they can't meet demand) and have a car on sale (and despite its inefficiency, it still has over twice the range of my Leaf so would be easy to live with).

    So spent all of this weekend prepping the V70 and getting it listed on Autotrader. I'm just hoping it sells easily...

    Battery

    Tesla are Li-Ion. When you get up to that size the advantages of Li-Ion are huge. All I was saying is that NiMH is a good compromise for a hybrid. All EVs (and to some extent the hybrids) have phenomenal acceleration simply because of the nature of electric motor power delivery, and not losing acceleration for gearchanges. Around town my 80kW (109bhp) Nissan Leaf is distinctly more sprightly than my 225bhp diesel Volvo - the leaf will show it a clean pair of heels up to 40mph. Conversely, once into its stride the Volvo will destroy the leaf from 50-80mph. I've driven a Tesla S 75D, and that was epic - since I'm used to EV driving it wasn't weird for me, but the ride/handling, grip and general feel to the drivetrain was actually not far different from the GS450h. Much more solid and capable than the utterly prosaic Leaf (with its macstruts and torsion beam suspension) or squirrely V70 (trying to put 470Nm through the front wheels with plenty of torque-steer) I for one can't wait for Lexus to come out with a full electric. Marry up their attention to detail and decent suspension design with a decent EV drivetrain and it would be a force to be reckoned with. Sadly Toyota have their heads in the sand about EVs and are in danger of missing the boat. They and Honda both tied themselves too deeply to hydrogen (which is NOT going to happen). I think we'll see some rather shocking changes in the auto industry in the next few years as some really big players (Ford, PSA, GM, FCA) suddenly discover that they needed to have started EV development 5 years ago to stay in business. Ford is in retreat (they're pulling out of selling cars in the USA, and will only offer pickups and SUVs) rather than trying to compete. As EV pickup trucks (Rivian, Bollinger, Tesla) and SUVs (Audi, Jag, Merc, Tesla, Rivian) start eating into their market share in those markets they will be in trouble. I sincerely hope that Toyota does not make the same mistake.

    Battery

    They still have not. Lexus Hybrids are still using Ni-MH batteries, as they are more appropriate to a hybrid. NiMH need less "looking after" than Li-Ion do, and are more rugged - NiMH doesn't need the same level of thermal management and safety gear. They are heavier and have lower volumetric energy density. The trade-off is worthwhile for a hybrid where you have ~2kWh of battery capacity (the GS450h spec is 1872Wh for the gen 3. Not been able to find info for Gen 4, but if the same 6.5Ah cells are used then the gen 4 GS450h is the same, and the GS300h is 1495Wh). In other words, the NiMH battery may be ~50kg heavier than an equivalent Li-Ion, but you'll save 20kg of encapsulation, thermal management, etc and cost. The NiMH application in hybrids is very well-developed. A full-EV with NiMH would be too heavy and lose too much space to the batteries, and the encapsulation and thermal management overheads don't increase linearly with battery size - they become less as the battery gets bigger (in percentage terms).

    So Whats Your Profession?

    Electronic Engineer. I've designed circuits and PCBs that have gone in Hi-Fi, fire alarms, coin handling machines and these days cars, among many other things.
  13. I love the V70, don't get me wrong. If ours had a power passenger seat we'd probably still be keeping it. However, I suspect we're talking different cars - SE Sport sounds like a P2 car (2001-2008)? Ours is a 2011 P3. P3s can turn a bit tighter than P2s (although ours has a lock limiter because it came from the factory on 8" wide wheels). P2s have a reputation for being out-turned by oil tankers. But my point was that Engine, trim level, wheel and tyre spec, tyre make and model all have big impacts, and would drastically affect the placement of any car in the table and that I suspect that is the case for the V70 - a T4 is probably the quietest V70, and they were more plentiful in sweden (where the test took place) than elsewhere where diesel is the defacto V70 powertrain.
  14. I'm not totally convinced by this piece... I (currently - it's making way for the GS) own a V70 and while reasonably refined and pretty good for wind noise and road noise (at least it is now, on Michelin Crossclimates), the engine is an ever-felt presence, even on the motorway. It didn't bother me for a long time, but once I got the Leaf and got acclimatised to that, the continual diesel growl in the V70 really began to grate. However, if the test was performed with a 6-cyl petrol V70 (either T6 or particularly a 3.2) then I can see that it would be quiet. Another experience I had was when visiting colleagues in Germany. During a visit in February I was given a lift from the office to the hotel in one of my colleague's BMW 425d Grancoupe. I was favourably impressed with how it rode and the engine refinement. Fast forward to September, and I was picked up from the station by another colleague in his 420d Grancoupe. I was shocked at the clattery coarseness of the engine! I struggled slightly with reconciling those two experiences. The next day I was driven to my meeting in the 420d, and then my first colleague with the 425d gave me a lift to the station after our meeting - the 425d was WAY quieter. I said this to him, and he replied (with very germanic matter-of-factness) "He bought the wrong one". The point being that the engine and trim level make quite a difference to this measure - for example, VW Bluemotion cars have (or at least used to) thinner glass and less noise absorbing material in order to save weight - but both at the cost of refinement and higher noise levels. I don't think it's as simple as "the Golf is noisy" - I'm sure that SOME golfs are, and that some are better than others. But I have no doubt that the LS600h is extremely quiet.

    Thanks all. Shahpor - it's rare that I'm called "interesting". 👍 We weren't ready to move on the car when yours was up for sale, although shortly after that Sidcup had a meteor blue one that we made an offer on. Meteor Blue was our top colour choice, followed by the Riviera Red of the car we got, with your Mercury Grey third. Silver, White and Black all tied for last place. There will be pictures, but first there will be polishing...
