2020 Cadillac XT4 Review and Buying Guide | Competence and curb appeal

The 2020 Cadillac XT4 is a handsome little crossover distinctively sized between two segments. This allows it to boast backseat space on par with larger SUVs like the Audi Q5, while being a bit more park-able and fuel efficient like the BMW X1. There should definitely be a Goldilocks "just right" thing going on for many shoppers. Cadillac's baby SUV also impresses on the technology front, boasting loads of standard, advanced features along with a user-friendly touchscreen interface that shouldn't be too hard to figure out. There are dynamic missteps, though. The steering, throttle and brake pedals lack the driver-oriented response and feedback we've come to expect from Cadillac's sharply tuned sport sedans, while also not exactly possessing the nice-and-easy isolation of Caddy's past. In either scenario, we're not sure it "drives like a Cadillac" despite some otherwise impressive engineering going on underneath that handsome skin. The XT4 is also pretty expensive given its features, size and interior quality. Competitors both larger (Acura RDX) and smaller (Volvo XC40) provide better value. Still, as we noted in our XT4 first drive, there's enough novel tech to provide bragging rights, it's obviously a Cadillac in design (and definitely not just a rebadged Chevrolet in execution), and it's a pleasing enough place to sit while scooting around in traffic. It has competence and curb appeal, which count for a lot. What's new for 2020? After being an all-new model last year, the XT4 heads into 2020 with some noteworthy features updates: Forward collision warning and automatic emergency braking are now standard, while the Premium Luxury trim level gets the hands-free power liftgate as standard equipment.   What's the XT4's interior and in-car technology like? The XT4's interior design isn't as memorable as that of its exterior, nor its stylish Volvo XC40 and Lincoln Corsair competitors. It's a bit generic, which just doesn't seem right for a Cadillac. Materials quality is acceptable when closer to its base price, but begins feeling less so as options are added and the price tag rises. We've also driven multiple XT4's with an annoying rattle in the B pillar. Standard infotainment technology is abundant. Apple CarPlay and Android Auto are included with the standard 8-inch touchscreen and benefit from a pair of USB ports: one standard USB-A and the other a newer USB-C.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

GM announces six new recalls, covering 3.5 million vehicles

General Motors has just initiated another crushingly large recall, this time affecting some 3.36 million vehicles built between 2000 and 2014 and sold in the US, Canada and Mexico. Once again, the issue surrounds the cars' ignition switches, which can be kicked out of the run position if they're carrying extra weight or if they experience a "jarring" event. In this particular case, though, GM will modify the keys, rather than the ignition itself.
A four-by-six-millimeter hole will be drilled into the key, which will more safely accommodate the weight of the key ring. As is usually the case, the work will be done free of charge. The recalled vehicles include the 2000 to 2005 Cadillac Deville, 2004 to 2005 Buick Regal LS and GS, 2004 to 2011 Cadillac DTS, 2005 to 2009 Buick Lacrosse, 2006 to 2008 Chevrolet Monte Carlo, 2006 to 2011 Buick Lucerne and 2006 to 2014 Chevrolet Impala. Only the Impala is still in production, and even then, it's only sold to fleet companies.
According to an official statement from GM, there have been eight crashes and six injuries due to this latest issue. As if this isn't a dire enough blow for GM, the company has announced five smaller recalls, covering 165,000 vehicles.
