Canada opens probe into 250,000 GM pickups, SUVs over brake performance

Transport Canada, the auto safety regulator, has opened a probe into braking issues in nearly 250,000 General Motors full-size pickups and SUVs after U.S. officials launched a similar probe last year, the agency said on its website. The U.S. National Highway Traffic Safety Administration (NHTSA) in November into 2.73 million U.S. 2014-2016 model year SUVs and pickups after receiving 487 reports of hard brake pedal effort accompanied by extended stopping distance that were attributed to deterioration of the engine-driven brake assist vacuum pump. Transport Canada's probe covers 249,700 2015 through 2017 model year vehicles including the Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon as well as 2014-2017 Chevrolet Silverado LD and GMC Sierra LD vehicles. The U.S. agency said it had reports of nine incidents of vehicles incurring damage as a result of colliding with another vehicle or fixed object at low speeds and reports of two injuries. NHTSA said if the pump fails to operate, the amount of brake power assist can be significantly reduced, extending vehicle stopping distance. The NHTSA sent GM an information request in a Feb. 7 letter. A GM spokesman said he had no update on the investigation. Reporting by David Shepardson; editing by Jonathan Oatis

Cadillac reveals stretched ATS-L in China

In the market for a new Cadillac, but need more space than an ATS can afford? Then you'll want to look at the larger CTS. Unless you live in China, where buyers - often chauffeured instead of driving themselves - seem to prefer a long-wheelbase version of a smaller sedan than upgrading to a larger one. For those buyers, Cadillac has released the new ATS-L.
Based on the existing ATS sports sedan, the ATS-L offers an extra 3.3 inches of rear legroom over the model we get here. As a result, the ATS-L stretches its wheelbase to 112.5 inches and its overall length to 186 inches, while riding a quarter-inch lower than the standard-wheelbase model, which itself was recently updated. That places its length in between the regular ATS and the CTS available Stateside.
Otherwise it's essentially the same sedan, but appears to ditch the base 2.0-liter four to offer either the 2.0-liter turbo four or 3.6-liter V6. Of course this model, produced locally for the Chinese market, isn't likely to make the transpacific voyage to US showrooms, so American buyers will still have to choose between the standard ATS, the larger CTS or the even larger XTS.

All-new 2019 Cadillac XT4 crossover debuts in New York

Cadillac spent years and years improving its mainline sedans, the CTS and ATS, turning them into awfully good impressions of BMWs from a few years before. The thing is, great sedans aren't selling, and crossovers sure are. Cadillac's XT5 is the only crossover in the lineup, something that's had American Cadillac dealers gnashing their teeth and wailing — although anyone they can upsell into an Escalade can staunch the bleeding. That brings us to the new XT4, which is smaller than the XT5 but even sharper than its bigger sibling. Let's take a closer look at this new two-row luxury crossover. For one, it's based on what Cadillac calls a unique platform. That may be true, technically, although it's likely related to the Equinox/Terrain on some level. Platforms are becoming quite flexible: Look at Volkswagen's MQB, under everything from Euro hatches smaller than our Golf to the three-row Atlas. Whatever else it is underneath the skin, all XT4s will share one powertrain: the corporate 2.0-liter turbocharged inline-four, paired to a nine-speed automatic transmission. View 14 Photos The engine puts out a healthy 237 horsepower and 258 pound-feet of torque, putting it just a hair underneath its closest domestic rival, the Lincoln MKC with the 2.0-liter EcoBoost. Of course, the 2.3-liter MKC beats the XT4 handily, but that's another story. Power is produced with the help of a twin-scroll turbocharger. All-wheel drive is available, with a driver-selectable rear axle disconnect to save a small amount of rolling friction. Cadillac estimates it'll be good for 30 MPG on the freeway, but we haven't seen official results to confirm that. A few other changes that'll affect driving: electro-hydraulic brake assist, a first for Cadillac and mainly a fuel-saving measure; and Continuous Damping Control, which alters the damper's valve continuously based on a number of parameters. It's almost certainly used here because it's lighter and less expensive than air suspension or MagneRide, and it is optional on XT4. CDC or no, all XT4s utilize a front strut and five-link rear suspension. All XT4s also ride on 18-inch wheels in various designs. The trim strategy is mildly interesting. The base model is the Luxury, and then you can choose a Sport (black exterior trim, unique wheels) or a Premium Luxury (bright trim and satin-brushed accents). The interior options are suitably upscale and premium, and we'll have more to say about them a little later when we can see this car up close.
