  1. Why Is the Q4 System So Underappreciated?

    Alfa Romeo Giulia General Discussion
    We could always take one apart. Anybody out there got a broken one (wrecked will do)? High gears are also used for comfort and fuel economy. It is not uncommon to find that the top speed of a vehicle is achieved in the next-to-highest gear.

    I finished installing new brake pads. All of them were worn down to the sensors and one was worn down to about 1mm at one corner. I drove a gentle 500 miles after the service pads light came on. As others have noticed, brake pad wear on the multi-piston solid mount calipers tends to be...

    Try If you do not understand Italian, only the drag race at about the 2 minute mark has metrics. I'm not sure why they are comparing Giulia Veloce to BMW 320d though; maybe the assumption is that with traction limited the power difference is not significant?

    Aside from the correction provided by @beaups, you are correct but we still do not have the answer to what the final ratio of the front drive is, assuming no clutch slippage. If the wheels are not slipping and the car is turning and the transfer clutch is engaged and the front drive ratio is...

    When the car is moving, pushing both pedals will cause a CEL to be thrown. However, you can push both pedals while Giulia is stopped with no CEL. I use this often to force the transmission into gear before a normal-ish start in order to reduce the initial hesitation that Giulia exhibits. I do...

    and yet the narrative still dodges the question: is the front wheel gearing higher or lower than the rear wheel gearing? While he said that the rear wheels turn faster than the front wheels when the AWD engages, that is simply the nature of rear wheels slipping*. The clutch in the transfer...

    Apparently wet, sticky Sierra cement is more harsh than your cold Chicago winter conditions. That or my 100 miles in the snow drive is more substantial than what you have taken on. I have had the wheel wells pack up more than once as well as snow accumulating inside the wheel barrel forcing it...

    Alfa Romeo Giulia Issues And Problems
    When I took delivery of my car I drove directly to the Ceramic coating place. The wipers always shuddered until I had the windshield replaced due to it cracking from a rock chip. Now they run as smooth as can be. Thus, I have to suspect an issue with your windshield rather than the windshield...

    What is wrong with this picture (besides being blurry)? Once there is less than 4mm of brake pad left, won't the rotor cut into the brake wear sensor wire? What am I missing?

    Alfa Romeo Giulia General Discussion
    That seems to be what Wikipedia says, at least for the transfer: https://en.wikipedia.org/wiki/BMW_xDrive Part of the "magic" however, is in the programming of the transfer control. It seems unlikely that BMW and Alfa would be the same in this regard, just like BMW 3 series and Alfa use...

    True, but then we are back to what 2.5% max overslip really means in this context. For example if the front ratio is the same as the rear ratio it means that torque can still be delivered to the front wheels even if they are spinning 2.5% slower than the rear wheels due to rear wheel slippage...

    By not engaging the front axle under some conditions, such as race mode and counter steering? Can you tell in any of the videos that the front wheels are being driven at all while the SQV is drifting? I see a little snow getting kicked out, but nothing like what is happening with the rear...

    Scraping is a function of the rate of change in slope rather than the absolute value of the slope. If your driveway has gentle transitions you should not have problems with scraping. Driveways with "sharp" transitions but small slopes are often a problem. This typically happens when there is...

    Only if Q4 is expected to force the car to drift sideways whenever it engages in a turn. I seriously doubt that is how it is designed. Also there is a transfer with gears between the transmission and the front axle and that transfer could have a drive ratio other than 1:1. I tried to find...
  15. Why Is the Q4 System So Underappreciated?

    Alfa Romeo Giulia General Discussion
    Maybe you have time to mess around on closed courses, but I drive on roads. If you drive like that on open highways you should have your license removed permanently before you kill someone. There is absolutely nothing in any of the posts about what speed the front wheels are driven at relative...

    Alfa Romeo Giulia Quadrifoglio
    ChuckRunning, Most of those cosmetic things are fixable, many of them easily fixable. Others are normal wear and tear such as the scuffs on the seat bolster and the rock chip at the rear of the skirt. The A pillar covers are notoriously difficult to properly attach. I have done it once, but...

    Alfa Romeo Giulia General Discussion
    I would prefer to get a clarification from @MacGeek on this subject. 1) If the car is driven in a straight line and no wheels are slipping the front and rear wheels are turning the same speed. 2) If the car is turning and no wheels are slipping and the car does not have rear wheel steering...

    My MY2018 Q4 built in Sept 2017 had NGK plugs in it, exactly the same as the plugs being sold by Alfissimo.

    One point of confusion regarding gear ratios is that we call higher gears is a lower numeric ratio. So, when I said "the gearing to the front wheels is about 2.5% higher" I meant the ratio is 2.5% lower. That is, the front wheels are driven at a faster speed than the rear wheels. Besides the...

    FWIW: I saw no complaints online about the quality of the service work at Steven's Creek. However, the front desk of the service department is apparently horrible with failure to answer inquiries, failure to communicate job completion (or not), failure to keep appointments, etc a constant...
