Cadillac CT6 PHEV battery shape a big departure for GM's plug-in hybrid tech

Anyone with any familiarity with the electric powertrain details for the two General Motors plug-in hybrids will have noticed that the information we have about the newly announced Cadillac CT6 plug-in hybrid has a lot of numbers in common with the Chevy Volt and the Cadillac ELR, like the 18.4-kWh lithium-ion battery pack and an expected all-electric range of 37 miles. We also noticed that the announcement calls the plug-in CT6 hybrid an actual plug-in hybrid and not an "extended range electric vehicle (EREV)," which is what GM calls the Volt and the ELR. This, of course, means we needed to ask GM some questions. Donny Nordlicht from Cadillac communications told AutoblogGreen that while the Volt and CT6 batteries are both 18.4-kWh, the shape is completely different. In the Volt/ELR, the battery is T-shaped (see it here). The CT6 has four seats, with a tunnel running between the two in the rear, as you can see here, but the battery in the CT6 PHEV is "a cube-shaped pack, which is between rear seats and the trunk," Nordlicht said. "There is no pass through." GM has not yet released any technical schematics about this pack, but Nordlicht said that, "The CT6's advanced mixed-material platform was designed to accommodate the PHEV system by design so that it minimally intrudes on the cabin space." It also means that the CT6 can be ordered as an optional PHEV, while the Volt and ELR were purpose-built plug-ins. GM is also distinguishing between the EREV and PHEV powertrains in its vehicles from this point forward. "We are not discarding the EREV language," Nordlicht said. "The CT6 utilizes a two-motor system mated to a 2.0T 4-cylinder engine, which is an all-new system to Cadillac." We assume that the PHEV packs will use li-ion cells from LG Chem, just like the EREVs do, but Nordlicht did not answer our question on that point. As for other details about the CT6 PHEV – like production, full dimension, and pricing – we will just have to wait until closer to when the vehicle launches for those. Related Video:

Cadillac's 4.2-liter Blackwing V8 to die with the CT6?

Cadillac's 4.2-liter twin-turbo Blackwing V8 debuted only last year, popping up in the CT6 V-Sport — now the CT6-V — with 550 horsepower and 627 pound-feet of torque. The engine's been stymied in every attempt to power a different Cadillac model since then. Its only two use cases have been a first and second run of the original, limited-edition super sedan and the CT6 Platinum V8 trim at a slightly detuned 500 hp and 553 lb-ft. Motor Trend cites "a highly placed source at GM" as saying that the Blackwing won't go into the coming high-performance version of the CT5-V nor in the next-gen Escalade. Left without options, there's a chance the Blackwing will die with the CT6, itself a sedan with its grille on the executioner's block just waiting for the bite of an ax that might or might not shortly fall. Cost-cutting has been tagged as the reason for this misfortune; Cadillac's sales malaise and lack of clarity as to how to turn sales around led GM to downsize the brand's allowance. The parent company chose to build the new CT5 on the Alpha platform used for the erstwhile ATS and CTS instead of the Omega platform underpinning the CT6. Along with that choice, the MT report says expense reasons nixed fitting the Blacking V8. We know the lower-tier V series CT5 will work with a twin-turbo 3.0-liter V6 making 355 hp and 400 lb-ft. When we heard spy video of the upper-tier V series CT5 out testing, the engine sounded like the 6.2-liter supercharged V8 that would be a carryover from the last model.  The XT6, also rumored to get some V sauce, simply can't fit the V8. Instead of sitting on the Omega platform as once planned, the XT6 rides on the C1XX architecture under other GM products like the Buick Enclave and Chevrolet Traverse. The C1XX engine bay doesn't have room for a stouter V6, much less a hi-po V8. The next-gen Escalade ruled itself out due to price issues in back, not in front. MT writes that the independent rear suspension supporting GM's next-gen full-sized SUV quartet has burned through cash in development, putting engineers a few direct deposits short of the funds needed to massage Blackwing installation. Earlier this year at least one report said the twin-turbo DOHC V8 could serve the top-spec next-gen Escalade. More recent reports of a performance-heavy next-gen Escalade have predicted the 6.2-liter supercharged LT4 V8 from the Chevrolet Camaro ZL1 and Corvette Z06.

Genesis cars win accolades, offer value — so why are sales so bad?

My high-school buddy Brent Cormier was so smitten with the Genesis G80 when he saw it at an event I hosted at SXSW in 2016 he bought a used 2013 Hyundai Genesis a short time later and fell in love with the car. "It surpasses my every expectation," said Cormier, a self-described "renaissance man" who owns and runs a real estate agency with his wife Laura, is a food service executive chef and part owner of Austin-based Thin the Herd Guitars. "I was locked into Mercedes and Audi for 10 years," he added. "And felt trapped in an endless pit of maintenance costs." After owning the Genesis over the past two years — including using it as an Uber and Lyft driver to earn extra cash — Cormier learned what some frugal luxury sedan buyers and a handful of car reviewers have discovered: Genesis offers great bang for the buck compared to other premium brands and can compete with the best in terms of performance, features and comfort. Hyundai's luxury brand also earned a prominent third-party endorsement last week when for the first time Genesis topped J.D. Power's 2018 APEAL study, surpassing German luxury-performance icon Porsche. The APEAL study (which stands for Automotive Performance, Execution and Layout) "measures owners' emotional attachment and level of excitement across 77 attributes," ranging from performance to comfort, and asks nearly 68,000 owners of new 2018 models to score vehicles on a 1,000-point scale. In its second year ranked as a stand-alone brand, Genesis earned an APEAL score that bumped it up 15 points to 884 and helped push it past Porsche — and past BMW, Lincoln, Mercedes-Benz, Audi, Volvo, Cadillac, Land Rover and Lexus, in order of ranking. Last month, Genesis also topped J.D. Power's Initial Quality Survey (IQS) for the first time this year. And both its models were awarded Top Safety Pick Plus ratings by the Insurance Institute for Highway Safety, among 11 Plus ratings in all for Korean vehicles. Despite high J.D. Power rankings and great reviews, Genesis U.S. sales were off 50 percent for the first six months of 2018 compared to 2017, and in June Genesis sold only 796 vehicles — the first time U.S. numbers dropped below 1,000 in a month. Part of Genesis's APEAL and IQS success can be attributed to its small product lineup: just two models, the G80 and G90 sedans, with a third, the 2019 G70, launching later this year. And while those numbers may help in J.D.
