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:

Remembering Pierre Cardin's automotive legacy

Pierre Cardin has passed away at age 98, and while the designer had a great impact on the world of fashion, he also brought his signature style to the automotive realm, chiefly with the unlikely partner of American Motors. At the dawn of the 1970s, AMC decided to seek out a little glamour for its freshly renewed product lineup by having famous fashion designers work their magic on AMC cars. The first model to get the fashion treatment was the Hornet Sportabout wagon, with a special Gucci edition that became available for 1972. Later that same year, Pierre Cardin's Javelin was introduced. The Cardin Javelin arrived midway through the '72 model year as an interior option package. The designer had submitted as many as 10 proposals to AMC, and the chosen selection was a black interior with a wild multi-hued stripe of silver, white, red and purple that grooved across the seats, touched the door panels and continued onto the headliner. "People should feel like they're sitting in a living room rather than a machine," the designer was quoted in ads introducing his eponymous Javelin. In a press release, AMC said, "Cardin takes an ultra-modern abstract approach to his interior design." The Cardin interior option package was available with specific exterior colors: Snow White, Stardust Silver, Trans Am Red, and Wild Plum. For the '73 model year, Diamond Blue was a new exterior color option. The Pierre Cardin option was only $85 and was offered exclusively on the Javelin SST, although it's reported that the Pierre Cardin option also appeared on a handful of Javelin AMX models. For 1973, you could officially get a Pierre Cardin Javelin AMX. A total of 4,152 were built over the two model years. AMC's next fashion special was the Matador coupe, but the automaker tapped Oleg Cassini for that gig. Pierre Cardin was not finished with the automobile business, though. In 1975, he put his touch on the Sbarro Stash, an obscure supercar based on the SV1, with the result displayed at the Paris auto show. The designer next customized a run of early-'80s Cadillac Eldorados, and this time the treatment extended beyond the interior. A redesigned front end featured hidden headlights behind a full-width horizontal-car grille but unfortunately made the already-considerable front overhang even longer; the rear treatment was similarly modified with the factory vertical taillights replaced with horizontal units.

We really want to use an eCrate to restomod an old GM car. Here's what we'd build

You hopefully saw the news today of GM's introduction of its Connect and Cruise eCrate motor and battery package, which effectively makes the Bolt's electric motor, battery pack and myriad other elements available to, ah, bolt into a different vehicle. It's the same concept as installing a gasoline-powered crate motor into a classic car, but with electricity and stuff.  This, of course, got us thinking about what we'd stuff the eCrate into. Before we got too ahead of ourselves, however, we discovered that the eCrate battery pack is literally the Bolt EV pack in not only capacity but size and shape. In other words, you need to have enough space in the vehicle to place and/or stuff roughly 60% of a Chevy Bolt's length. It's not a big car, but that's still an awful lot of real estate. There's a reason GM chose to simply plop the pack into the bed and cargo area of old full-size SUVs. Well that, and having a rear suspension beefy enough to handle about 1,000 pounds of batteries.  So after that buzz kill, we still wanted to peruse the GM back catalog for classics we'd love to see transformed into an electric restomod that might be able to swallow all that battery ... maybe ... possibly ... whatever, saws and blow torches exist for a reason.  1971 Buick Riviera Consumer Editor Jeremy Korzeniewski: If you’re going to build an electric conversion, why not do it with style? ThatÂ’s why IÂ’m choosing a 1971-1973 Buick Riviera. You know, the one with the big glass boat-tail rear end that ends in a pointy V. Being a rather large vehicle with a big sloping fastback shape, IÂ’m hoping thereÂ’s enough room in the trunk and back seat to pack in the requisite battery pack. That would likely require cutting away some of the metal bulkhead that supports the rear seatback, but not so much that a wee bit of structural bracing couldnÂ’t shore things up. The big 455-cubic-inch Buick V8 up front will obviously have to go. Remember, this was the 1970s, so despite all that displacement, the Riviera only had around 250 horsepower (depending on the year and the trim level). So the electric motorÂ’s 200 horsepower and 266 pound-feet of torque ought to work as an acceptable replacement.   1982 Chevrolet S10 Associate Editor Byron Hurd: OK, so the name "E-10" is already taken by a completely different truck, but let's not let labels get in the way of a fun idea.
