    Spying: 2020 Chevrolet Suburban Is Hiding Something

      Major changes for the suspension

    The lengths that automakers go to with camouflaging vehicles continues to amaze us. Case in point, the first spy photos of the next-generation Chevrolet Suburban has hit the internet. General Motors has covered up every surface, including the underside. That's because the new Suburban appears to be ditching the solid rear axle for an independent setup. We know this as a spy photographer found the right spot where there was minimal camouflage and captured it.

    Why is Chevrolet switching to an IRS setup? It might have to do with the new Ford Expedition which moved to independent rear suspension. A source told Autoblog that Chevrolet wouldn't have fit IRS because it was expensive, but plans changed when the Expedition made a big splash with it. Of course, IRS could have been in the cards for some time. Nevertheless, this setup will help improve ride quality significantly.

    Engines are expected to mirror the new Silverado, which might include the new turbocharged 2.7 four-cylinder.

    They dominated sales though.. It was smart of hold off a generation to save the R&D cash for anything else.

    This kind of pictures screams IRS. They could have done a far better job if they really wanted to keep it less noticable.

    Very cool as you know this will go into the Yukon and Escalade.

    Q: What is the advantage of a solid rear axle vs. an IRS other than cost?

    IRS allows for a lower rear frame and lower rear floor--more legroom for 3rd row passengers, lower cargo area floor.  Compare the Expedition vs the GM full sizers.

    Solid axles generally have higher weight capacities... but that's not really a factor in SUVs. Pickups are unlikely to ever go IRS.

      Chevrolet has canceled the Malibu Hybrid for the 2020 model year.  What? You forgot they even offered one?  It's not surprising. 
      It's tough out there for slow selling sedans these days and the Malibu Hybrid was probably one of the slowest selling of the General's current lineup. The move leaves GM with no full hybrid vehicles at all in the lineup. This comes after the cancellation of the plug-in Chevy Volt earlier this year. The only electrified vehicle, for now, is the diminutive Chevy Bolt. GM is rumored to be working hard on an electric or electrified truck, and has plans to electrify most of the Cadillac lineup, even going so far as to promise the UAW that the Lordstown plant would reopen as a battery factory. 
      The Malibu Hybrid used a 1.8 liter 4-cylinder and an electric motor combination to make 182 horsepower.  The sedan could drive on electric alone up to 55 mph, but it lacked a plug-in option.  It came only in the upper LT trim and started at $29,095 before delivery charges.

      General Motors is planing a range of updates for their full-size trucks starting in the 2021 model year, beginning with updated interiors. Also coming is a Silverado ZRX aimed to take on the likes of the Ford F-150 Raptor and the Ram 1500 Rebel.  The ZRX would come with an improved off-road suspension, special DSSV Dampers like on the Colorado ZR2, rear and front locking differentials, and improved approach and departure angles. 
      If Chevy uses the same recipe they did on the ZR2, the ZRX will likely also get unique front and rear fascias.  One thing that isn't changing though is the powertrain. It's rumored that the ZRX will continue to use the same 6.2 liter V8 with 420 horsepower and 460 lb.-ft of torque.  This is disappointing as the Raptor and Rebel TRX both get more powerful engines than their on-road counterparts. 
      If these plans come to fruition, expect the Silverado ZRX to come out in 2021 as a 2022 model.

      General Motors announced a recall Wednesday of 3.46 million GM trucks and SUVs for a braking issue that has been linked to 113 accidents and 13 injuries.  The problem arises from a vacuum pump issue where the pump make less vacuum over time, thereby increasing the braking effort. The pump is lubricated by engine oil and can accumulate debris and oil sludge lessening the pump's effectiveness.
      The recall covered model years 2014 - 2018 of Cadillac Escalade, Chevrolet Silverado, Suburban, and Tahoe, and GMC Sierra and Yukon. 
      GM told the NHTSA that the pump design was only used during those years of manufacture. 
      In a smaller recall, GM is recalling 177,000 2018 Chevrolet Malibus with the 1.5-liter Turbo engine where an error in the engine control computer could disable the fuel injectors.
