Cadillac considering more engines, Vsport model for Escalade

Want to roll in the latest Cadillac Escalade? You can get it with a 6.2-liter V8... or a 6.2-liter V8. Cadillac only offers the one engine option. But that may soon change.
According to the latest from Automotive News, Cadillac is contemplating a couple of new powertrain options for its blingin' big ute. The report suggests a twin-turbo V6 and a V6 turbodiesel could be offered, and that Cadillac could create a Vsport version of the Escalade like it offers on the new CTS sedan.
The more diverse engine offerings would help attract buyers from the new Lincoln Navigator, its prime competitor, which switched from a 5.4-liter V8 this year to a 3.5-liter twin-turbo V6. The turbo V6 engines (both gasoline and diesel) would also help Cadillac market the Escalade overseas - particularly in Europe, where higher fuel prices preclude the prospect of driving a big V8 SUV for many buyers. Escalade sales have dropped from 35-40k units in the mid-2000s to around 12,000 the past couple of years.

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.

2016 Cadillac ATS-V brandishes 450 horses and 6-speed manual

Details about the hotly anticipated 2016 Cadillac ATS-V are tumbling out, and they look to be everything we could ask for in a high-performance Caddy coupe.
According to Road & Track, the ATS-V will use a version of the twin-turbocharged 3.6-liter V6 from the CTS Vsport, but the wick will be turned up to 450 horsepower and 445 pound-feet of torque. In glorious news for driving enthusiasts everywhere, that potent mill will be available with either a six-speed manual or eight-speed automatic.
According to R&T, the engine has a heap of high-performance tech to let it make the extra ponies, including titanium connecting rods, two water-to-air intercoolers, titanium turbines for the turbos and an additional radiator dedicated to cooling the gearbox and electronically locking differential. Keeping it all planted are a set of Michelin Pilot Super Sport tires, and a suspension with 50 percent more roll stiffness.
