Cadillac gives ATS, CTS new V6 for 2016

Replacing the existing 3.6-liter V6 in the Cadillac ATS and CTS is... another 3.6-liter V6. But this one promises higher output, while consuming less fuel, and making less noise. Like the V8s in the CTS-V and Escalade, it's got cylinder-deactivation technology to cut it down to a four-pot under lighter loads, as well as automatic stop/start, and comes mated to an eight-speed automatic transmission. The new engine produces 335 horsepower and 284 pound-feet of torque. That's a modest improvement over the 321 hp and 275 lb-ft mustered by the unit it replaces. But it also delivers an approximate improvement of nine percent in fuel economy and eight percent in carbon emissions. That's what we'd call a win-win, even if it's a modest one. Of course, those ATS or CTS buyers attracted to higher efficiency will still likely go for the 2.5-liter inline-four or the 2.0-liter turbo four. And those more inclined towards performance will be tempted by the 3.6-liter twin-turbo V6 in the ATS-V or CTS Vsport – or the 6.2-liter supercharged V8 in the CTS-V, for that matter. But those customers looking for the best of both worlds will surely be pleased by the improvements the new atmospheric V6 and 8-speed gearbox bring to the table.

Now as 2016 model year production begins, Cadillac adds new fuel-saving technologies. Active Fuel Management and Automatic Stop/Start technologies, and widespread use of a new 8-speed transmission, are combining to raise fuel economy ratings and reduce emissions in Cadillac's portfolio. Cadillac's all-new six cylinder engine contains Active Fuel Management, or cylinder deactivation, technology enabling it to seamlessly switch from six-cylinder to four-cylinder operation under certain light-load conditions, while maintaining excellent performance. The new 3.6-liter engine is part of the 2016 ATS and CTS product lines. Additionally, the Cadillac Escalade luxury SUV's V8 will shift to four-cylinder operation in many daily driving conditions, as will Cadillac's all-new high performance CTS-V sedan.

How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.

Cadillac Elmiraj sedan RWD flagship finally caught testing

While we still have no insight as to it being named Elmiraj, STS or some other permutation of the -TS nomenclature ("LTS" has apparently been registered by GM, as well), new spy shots give us proof positive that Cadillac is indeed hard at work on a rear-wheel-drive flagship model. Spied for the very first time in some north country testing, these shots provide a first look at the upcoming range-topper from Cadillac.
Impressively long and large bodywork ride atop new General Motors' corporate Omega rear-drive architecture here. Heavy cladding over camouflage may discourage finding any details, but the overall, sharp-edged and blocky design is clearly reminiscent of what we've seen on the new CTS and the recently debuted ATS coupe. A strong, wheels-at-each-corner stance helps emphasize the length of this stretched Caddy, and everything about the proportions seem spot-on for a new fullsize flagship for the brand.
It's quite possible that Cadillac will ultimately festoon this large sedan with detailing reminiscent of the original Elmiraj coupe, though thus far we've only seen prototypes wearing four-doors.
