  1. The 2019 Cadillac XT4 is in production, on their way to dealerships and out for test drives around North America. Reviews have been very positive and people have a variety of love / hate it for the design. Even here on Cheers and Gears various members have a passion on how plastic is being used on the front and rear of the car. With that it is time to take a closer look at some of the tech on this newest CUV from Cadillac. I found sandyblogs.com and the writers Tech Link. Here they do a pretty good job of pointing out the various tech on new auto's. I wanted to bring this into C&G for discussion and see what you all think. Tech open for debate: XT4 Electro-hydraulic brakes Turbo Charged 2.0L engine Plastic Engine Oil Pan Multipoint Air filter sensors 9 speed transmission with shift by wire Active Twin Clutch AWD system Active Sports Suspension Next Generation Infotainment system Rotary Controller Driver Assistance systems Hands Free power liftgate 22 new specialty tools to work on the auto The XT4 is the first GM auto to use their new brake control system that takes up considerably less room under the hood compared to a traditional Vacuum assisted power braking system. This new brake system is 13 lbs lighter than the old one it replaces. There are new braking sensors, brake pad sensors, wheel speed sensors and a new Power up self test. This makes the braking system a very self aware system for faster response with greater safety. We then have the feature heavy 2.0L Turbo 4 motor with AFM (Active Fuel Management), SIDI (Spark ignited Direct Injection), DOHC (Dual Overhead Camshafts), VVT (Variable Valve Timing) with this being the first new engine built on CSS or cylinder set strategy. This engine also uses an electric water pump using a built in local interconnect Network to manage cooling. Oil is the Gen 2 full synthetic SAE 0W-20 and uses a hardened plastic oil pan connected to the engine block. This oil pan helps to reduce the overall weight by a few pounds. The DIC in the auto is able to manage the multiple air sensor points on when you need to change the air filter. The 9 speed transmission is one of the smallest ever and uses electronics to shift gears via input from the EPS (Electronic Precision Shift). This does have a slightly different pattern over the XT5 as it is just a straight up and down only. The AWD twin clutch system is electronically controlled and allows a perfect 50/50 between front and back wheels and yet allows power up to 100% to be sent to the wheels with the best traction. The active Sport Suspension adjusts to the road every 2 milliseconds and allows the driver to change between tour, sport or AWD mode at any time. Cadillac is rolling out their next generation infotainment system. Higher quality graphics with a much faster more responsive system. faster to touch as well as voice. This system supports NFC (Near Field Communication) for easy pairing of your phone and the system. Besides touching the screen or a button, there is a rotary controller now allowing ease in access among the menus and feature function. Driver assistance systems is easiest to just post their long list of what this includes: Safety Alert Seat Rear Camera Mirror Surround Vision 360-degree Camera Lane Change Alert with Side Blind Zone Alert Lane Keep Assist with Lane Departure Warning Front/Rear Park Assist Rear Cross Traffic Alert Front Pedestrian Braking Forward Collision Alert Forward/Reverse Automatic Braking Head-Up Display Automatic Parking Assist with Braking Final feature is one that Cadillac competitor has had for years, Hand Free power liftgate. When you are within 6 ft of the rear of the auto with the fob in your pocket, you can just swing your foot and it will open the rear liftgate. The final listed item is all the new tools needed to work on the XT4. You can review the list on the Tech Link 1. Tech Link 1 Tech Link 2
