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.

Super Cruise’s failsafes

Even though Super Cruise is not a fully autonomous system, it incorporates redundancies like those used in aircraft to ensure failsafe operation. Before taking off on a 700-mile, 11-hour test drive of the system — and putting my life in its hands without my hands on the wheel — I sat down with Daryl Wilson, lead development engineer for Super Cruise, to get a deep dive into the system and its critical safety backups. Autoblog: First, what makes Super Cruise different from similar systems? Wilson: The key differentiator for Super Cruise is hand-free driving. It's an industry first in that respect. Our competitors require the driver at minimum to place their hands on the wheel with some frequency to ensure that the car knows that the driver is there. We don't. Two key technologies allow us to do this. One is our Driver Attention System, which is our methodology for making sure the driver is engaged with the vehicle and engaged with the road. This is a driver assist system, not a fully autonomous system. So it requires driver engagement. We use an infrared camera that constantly monitors the driver's face to determine the direction they're looking. We're looking for the driver to be what we call on-road — not on the center stack, not to left or right or down. That's all done by the tracking of the face. We also track that the eyes are open. It's infrared because at night you need to illuminate the face and you can't be shining a light into the driver's face. Then we have our lidar mapping that provides a foundation for control and redundancy to ensure safe performance. Autoblog: How does the mapping act as a redundant feature? Wilson: This system is only for use on divided, controlled access highways. What I mean by a divided highway is something more than a painted line between you and oncoming traffic. Whether that's a grassy area in between the lanes or a concrete barrier, anything that separates you from oncoming traffic. That's the divided highway part. The controlled access part is entrance ramps and exit ramps. Not with roads that cross at grade, with traffic crossing at the same level. To do that we geofenced these roads to ensure that operation is only allowed in these conditions. We don't just recommend you use it there; we ensure that you only use it there.

2020 Cadillac XT6 fuel economy announced

Thanks to the EPA's fuel economy website, we finally know how frugal the 2020 Cadillac XT6, the brand's first three-row crossover, is with gasoline. The most efficient is the front-wheel-drive version, getting 18 mpg in the city, 25 on the highway and 20 in combined driving. The all-wheel-drive XT6 is just barely behind it with 17 mpg in town, 24 on the highway, and 20 combined. Both versions share the same 3.6-liter V6 with 310 horsepower and 271 pound-feet of torque and the same nine-speed automatic transmission. These numbers put the Cadillac XT6 very much on par with the competition. Both the four-cylinder and V6 versions of the Audi Q7 get 21 mpg combined, just beating the XT6, and both feature standard all-wheel drive. The Q7 with an inline-four makes less power at 255 horses while matching the XT6's torque at 273 pound-feet. The V6's 329 horsepower and 325 pound-feet beat the Caddy, though. Both Audi and Cadillac have almost the same starting price at about $53,000. Every version of the Acura MDX tops the XT6, including the least-efficient MDX A-Spec, which manages 21 mpg in combined driving. The non-A-Spec all-wheel-drive model gets 22 mpg combined, and the front-drive MDX hits 23 mpg. But the best is the Sport Hybrid that delivers 27 mpg combined. All of the non-hybrid MDXs are less powerful and less torquey than the Cadillac, though, at 290 horsepower and 267 pound-feet of torque. The Sport Hybrid is a bit more powerful and torquey than the Cadillac with 321 horsepower and 289 pound-feet of torque. The Acura does start at a lower price of just over $45,000. The XT6 does beat one of its three-row crossover rivals, though. Its 20 mpg combined rating is comfortably ahead of the Mercedes-Benz GLS-Class's most efficient V6 version at just 18 mpg. But the Mercedes also delivers 362 horsepower and 369 pound-feet of torque, and there are even more powerful, but less efficient, V8s on offer. The Mercedes is much more expensive than the Cadillac with a base price of over $70,000.
