Such Sweet Sorrow: Cadillac's CTS-V gets an Irish wake

As the saying goes, all good things must come to an end. The honkin', stonkin' second-generation CTS-V, powered by Cadillac's brawny supercharged 6.2-liter V8 has been a very good thing. And now that the 500 final coupes – the only CTS-Vs designated 2015 models – have been built (just five remain unsold as of this writing), it is indeed a good thing that's come to an end. But Cadillac is not letting 2009–2015 CTS-V go gently into that good night, even as its replacement is poised to debut in just in just two months at the 2015 Detroit Auto Show. Instead, Cadillac invited us to Austin's Circuit of the Americas racetrack for what it called an "Irish wake" for the model that has proven to be one of the quickest and most charismatic models in General Motors' history. If you don't know what an Irish wake is, if you envision storytelling, songs, debauchery and more than a little liquor, you'll be in the ballpark. In this case, though, adrenaline substituted in for the booze, with squealing tires and shrieking V8s providing the singing. The debauchery took the form of an all-you-can-drive lapping of COTA in all three bodystyles – coupe, sedan and wagon – and the stories were told by the grins plastered on our faces all day. First and foremost, we'll miss the CTS-V's perfect balance of luxury and sportiness. Even after six years with no major changes, the CTS-V is surprisingly spry. Certainly, you never forget that it's a heavy thing, weighing in anywhere between 4217 pounds for the manual-equipped coupe to 4424 for an automatic wagon, but with 0-60 times of about four seconds and the ability to hit about 150 mph on COTA's back straight, the Vs remain an absolute hoot on the track. Sure, some of its details – the blocky front fascia shapes and the spoiler on the sedan and coupe models, for example – look a bit dated, but the overall design still looks sufficiently badass. The interior design has worn pretty well, too, and however Cadillac may feel about center stack buttons being so last decade, we favor them over the capacitive-touch madness of today's CUE system. We're not going to bother doing another full review of the car here, but suffice it to say, there is plenty we will miss. First and foremost, will be the CTS-V's perfect balance of luxury and sportiness. Rumor has it that Cadillac will offer the 6.2-liter LT4 V8 in the next generation (we predict about 600 hp), but we hear that the new car will skew more toward luxury than balls-out performance.

Cadillac CT6 gets a plug in Shanghai, will come to US

Don't call it the third coming of the Chevy Volt. The unsurprising debut of the Cadillac CT6 PHEV in Shanghai today has a powertrain that sounds an awful lot like the one that can be found in the Volt and the Cadillac ELR. The plug-in CT6 – identical to the CT6 that debuted in New York earlier this month – has an 18.4-kWh lithium-ion battery (just like the 2016 Volt) and offers an all-electric range of around 37 miles. It also copies the "Regen on Demand" feature from the new Volt and the battery cells "use the latest generation cell chemistry found in other GM plug-in vehicles." But Cadillac President Johan de Nysschen doesn't see the two powertrains as similar in at least one important way. General Motors calls the Volt and the ELR "extended range electric vehicles" (EREV) but in a statement, de Nysschen says that the plug-in hybrid CT6 is, "an ideal platform for Cadillac to offer its first plug-in hybrid." That GM is using the PHEV terminology rather than EREV is going to be important to some, even if the practical difference is only semantic. And yes, we all understand the irony of de Nysschen – the same guy who has a history of speaking ill of plug-in cars – hyping them now. Back when he worked for Audi, he said the original Volt was too expensive for what it offered and was thus, a car for "idiots." Speaking in Shanghai today, de Nysschen said the new CT6 PHEV was, "an EV without any of the disadvantages or range constraints," according to Automotive News. If the batteries are similar to GM's other EREV/PHEV cars, the CT6 powertrain is at least different. The ELR uses a 1.4-liter engine, while the new Volt has a 1.5-liter four-cylinder mill. The CT6, on the other hand, has a 2.0-liter turbo four-cylinder engine with direct injection. There is also an "all-new rear wheel electric variable transmission (EVT) with exclusively designed motors," that will give the CT6 PHEV, "smooth, spirited acceleration." The EVT is a two-motor-unit that uses three planetary gears. Maximum overall system output is 335 horsepower and 432 pound-feet of torque. Perhaps most interesting for American audiences is the fact that GM's press release, available below, makes multiple references to US-market sales of the PHEV. Official details on the EV range and fuel economy will be made available closer to the car's US launch.

Hennessy wastes no time in supercharging the 2015 Cadillac Escalade

The ink is still drying on the all-new 2015 Cadillac Escalade sales brochures, but that hasn't stopped Texas-based Hennessey Performance (HPE) from leaping out of the gate with its own high-performance variant. In stock form, the big fourth-generation Cadillac flagship arrives with a new small block naturally aspirated 6.2-liter Ecotec3 V8 delivering 420 horsepower and 460 pound-feet of torque. Fresh out of the showroom, the 5,900-pound SUV will sprint to 60 mph in 5.9 seconds.
While that is plenty fast for some owners, others don't want to be shamed by a 550 horsepower Mercedes-Benz GL63 AMG or a 510 horsepower Land Rover Range Rover Sport - both will leave the stock Escalade at a stoplight.
The team at HPE has come to the rescue with its HPE550 supercharger upgrade, which includes a belt-driven supercharger, air-to-water intercooler, recalibrated engine management software and a three-year/36,000 mile powertrain warranty. With 6 psi of boost, the direct-injected 6.2-liter is tuned to deliver an impressive 557 horsepower and 542 pound-feet of torque - gains of 32 percent and 18 percent, respectively, over stock. Although HPE isn't releasing performance figures as of yet, our math says that should be enough power to put the two Europeans in the Cadillac's rearview mirror. The company also offers a set of 20-inch lightweight H10 forged monoblock wheels, to further improve performance.
