2014 Cadillac XTS Vsport

Not long after bombing around the Milford Road Course in the new CTS Vsport, Cadillac invited me to try out its other new-for-2014 Vsport model: the XTS. And despite using the same twin-turbocharged 3.6-liter V6 from the CTS, the Vsport package takes on a whole new meaning here in Cadillac's softer flagship.
In the CTS, this trim perfectly bridges the gap between the standard models and the hardcore CTS-V, and is focused on being the best-driving version of the range without a standalone V badge. The XTS, however, has no proper V model, so the Vsport becomes the new range-topper for that line by default. But unlike the CTS Vsport, which uses rear-wheel-drive architecture and is focused on driving dynamics above all, the XTS is geared toward a much different customer.
The entire XTS experience is far more concerned with plush comfort than handling prowess, and while this Vsport model certainly ups the ante with more power and some mild suspension and steering tweaks, it's not exactly what we'd call a particularly engaging experience. But that doesn't mean it isn't good.

GM recalls 55,000 trucks, SUVs for separating axles, fuel pump failures

General Motors issued four separate recalls covering eight of its truck and SUV models for issues related to fuel pump and half-shaft failure. In total, the four campaigns include more than 55,000 vehicles spread out over three brands and six model years, but they've sorted themselves neatly into two categories. Let's dive in.  Axle separation Four models are being recalled for potential axle separation: The 2023 Cadillac XT5, 2023 GMC Acadia, 2023 Chevy Blazer and 2023 Chevy Traverse. The number of units affected is incredibly small (10 units each times two recalls, for a total potential population of just 20 cars). In each case, a small number left the factory with half-shaft assemblies that may have been missing the retention rings that keep them in place, possibly allowing the axles to separate or eject from the transmission. In the case of the XT5 and Acadia, it's the right-side axle assembly; Chevy dealers, however, will have to check the left side.  Fuel pump failure Again, we have multiple vehicles being recalled for similar issues, but in this case they're a bit more distinct. The first of these recalls covers the 2021-2022 Chevy Equinox and 2022 GMC Terrain. GM says a supplier-initiated change may have led to fuel pumps shipping with inadequate clearances to allow for the prescribed flow of fuel, meaning the pump could starve the engine. Customers experiencing the issue may see a check engine light and experience engine hesitation. In some cases, the cars may not start at all. Chevy and GMC will replace the units in question with correctly specified pumps.  The second recall covers a fairly specific cross-section of GM's HD truck lines. 2017-2019 Silverado and Sierra HD trucks sold with the diesel engine and a dual-tank configuration may have shipped with a rear fuel pump that is susceptible to fouling by debris, preventing fuel from properly transferring to the front tank, or, in extreme cases, resulting in a collapse of the rear tank. This issue can lead to inaccurate/erratic fuel tank readings, engine hesitation, a check-engine light or failure to start.  In both cases, GM will inspect and replace faulty units free of charge for customers. Expect notifications to be delivered by March.  Related video: Recalls Cadillac Chevrolet GMC Ownership Safety Truck SUV

How Cadillac improved power output in 2016 ELR by 25 percent

Earlier this year, Cadillac announced that the 2016 ELR would come with a big price drop and a powertrain that packs 25 percent more power output. That's a lot more oomph, but it didn't sound like the Caddy engineers made any major changes to the engine or motors. So, what happened? Let's refresh our memories with the numeric details. The 2016 car is 1.5 seconds quicker to 60 miles per hour than the 2014 model (there was no 2015), down to 6.4 seconds. The 2014 put out 295 pound-feet of torque. For 2016, it will be 373 lb-ft. The specific breakdown of the various components in the powertrain has not been disclosed, but from what we can tell, the two electric motors and the 1.4-liter inline-four engine in the new ELR are not that much different than those in the old one. Sam Abuelsamid, senior research analyst at Navigant Research (and former writer here at Autoblog) said that any of the unspecified upgrades would be difficult to tell on a part-by-part basis, but the overall effect will be noticeable. "The changes to the ELR as I understand them are analogous to getting more performance out of a 1965 Mustang with the entry version of the 289 cubic-inch V8. You can replace the carburetor with a larger version that enables more air and fuel to flow into the engine, thus producing more power. The basic engine hasn't changed, but power capability is being unleashed by feeding it more." "Cadillac has changed components in the power electronics to enable more current flow into the motor and thus produce more torque. When you do this in the Mustang, you probably need to replace the rear axle gears and use a beefier clutch to transmit the power to the wheels. Similarly, the ELR probably has some upgraded clutches, bearings, and gears to withstand the increased total output." Cadillac spokesperson David Caldwell told AutoblogGreen in an email that the new ELR does indeed have more than just new lines of code. "One could not 'reflash' a previous ELR to get the performance of a 2016," Caldwell said. "If one only changed software you would not get the performance upgrade fully, as the 2016 creates higher current, more power. So these have been upgraded physically – hardware.
