Teaching autonomous vehicles to drive like (some) humans

While I love driving, I can't wait for fully autonomous vehicles. I have no doubt they'll reduce car accidents, 94 percent of which are caused by human error, leading to more than 37,000 road deaths in the U.S. last year. And if it means I can fly home at night in winter and get safely shuttled to my house an hour-plus away — and not have to endure a typical white-knuckle drive in the dark with torrential rain and blinding spray from 18-wheelers on Interstate 84 — sign me up. Autonomous technology will also take some of the stress, tedium and fatigue out of long highway drives, as I recently discovered while testing Cadillac Super Cruise. AVs are also supposed to eventually help increase traffic flow and reduce gridlock. But according to a recent Automotive News article, as the first wave of AVs are being tested on public roads, they're having the opposite effect. Part of the problem is they drive too cautiously and are programmed to strictly follow the written rules of the road rather than going with the flow of traffic. "Humans violate the rules in a safe and principled way, and the reality is that autonomous vehicles in the future may have to do the same thing if they don't want to be the source of bottlenecks," Karl Iagnemma, CEO of self-driving technology developer NuTonomy, told Automotive News. "You put a car on the road which may be driving by the letter of the law, but compared to the surrounding road users, it's acting very conservatively." I get it that, like teen drivers, AVs need a ramp up period to learn the unwritten rules of the road and that a skeptical public has to be convinced of the technology's safety. But this is where I become less of a champion on AVs, since where I live in the Pacific Northwest we already have more than our share of overly cautious human drivers. Since moving here 12 years ago, I've found it's an interesting paradox that a region famous for its strong coffee, where you'd think most drivers would be jacked up on caffeine, is also the home to annoyingly measured motorists. As an auto-journo colleague living in Seattle so aptly put it: "People in the Pacific Northwest drive as if they have nowhere to go." If you drive like me and always have somewhere to go — and usually are in a hurry to get there — it's absolutely maddening.

Cadillac to expand V-Series but discontinue CTS-V and ATS-V

Cadillac said Tuesday it will expand its V-Series performance sub-brand with the arrival of the CT6-V sedan in 2019 ( formerly known as the CT6 V-Sport), with plans to add high-performance variants across its portfolio. The flipside to that expansion is the sunsetting of its two existing V-Series performance cars, the ATS-V (both coupe and convertible) and CTS-V sedan. Two new unspecified sedans will slot below the CT6 in Cadillac's lineup, a spokesman said. The CT6-V will arrive next spring, roughly a year after it bowed at the New York auto show. It will feature Cadillac's new "Blackwing" V8, a twin-turbo engine that displaces 4.2 liters and produces an estimated 550 horsepower and 627 pound-feet of torque, sending it through GM's new 10-speed automatic transmission to drive all four wheels. A less-aggressive version of the engine will also appear in the CT6 Platinum model, offering 500 horsepower and 553 lb-ft of torque. "Beginning with the debut of the CTS-V Sedan in 2004, the V-Series sub-brand sparked new life into Cadillac," Mark Reuss, executive vice president and president of GM Global Automotive Group and Cadillac, said in a statement. "As a result of the overwhelming response the CT6 V-Sport received when revealed in early 2018, we've decided to formally make it a V-Series, signaling the expansion of V-Series." View 61 Photos A Cadillac spokesman tells Autoblog the 2019 model year will be the last for the ATS-V and CTS-V. The ATS-V is powered by a twin-turbo 3.6-liter V6 that's good for 464 hp and 445 lb-ft of torque, an increase of 262 hp and 173 lb-ft from the base, four-cylinder ATS, which is also set to go to pasture at the end of the 2018 model year. The CTS-V, meanwhile, boasts a 6.2-liter supercharged V8 under its carbon-fiber hood that puts out 640 horsepower and 630 pound-feet of torque, good for a 3.7-second 0-60 mph time and a top speed of 200 mph. In a Quick Spin review last year, Autoblog Editor-in-Chief Greg Migliore called the car "old-school muscle in an Esquire-approved suit. It's 'roids and cufflinks." As for what's next for an expanded V-Series, Cadillac has the new XT4 crossover, and already other companies are banking on performance versions of crossovers. Cadillac's also developing a less expensive luxury sports sedan called the CT5. It's also said to be planning a production version of the Escala concept starting in late 2021, so those could be possibilities.

[UPDATE] Cadillac Blackwing gets ticket to Italy, to go to work in a supercar

UPDATE: It seems MAT's belief it had secured a supply of Cadillac's 4.2-liter Blackwing V8 was premature, and based on a handshake deal before GM sold its Turin engine center to Italy's Punch Group. Shortly after Hagerty ran the story, GM sent a statement to the outlet reading, in part, "We do not have an agreement in place with Manifattura Automobili Torino (MAT) to provide or sell the Blackwing engine. ... Our team is following up with MAT president Paolo Garella to discuss the misunderstanding." MAT also submitted a statement to Hagerty, saying, in part, "We thank GM for the clarification. Although a signed agreement was not finalized between the parties, we were under the impression that our counterpart was committing to making this engine available to MAT at conditions yet to be defined. ... We hope that this misunderstanding will not compromise our relations with GM and possible future collaborations." The original article follows: Some necessary cost-cutting at Cadillac led to switching the new CT4, CT5, and Escalade to older platforms. The revised architecture plan meant Cadillac's newest top-tier products couldn't fit Cadillac's newest top-tier engine, the 4.2-liter twin-turbo DOHC V8 known as Blackwing. That engine would serve limited duty at full power in the now-dead CT6-V, and at reduced output in the CT6 Platinum V8 trim before ending its bright, brief domestic life. But the story isn't over, the rebirth of Blackwing coming from a most surprising locale: Turin, Italy. Before the canceled Geneva Motor Show, Hagerty spoke to Paolo Garella, CEO of Manifattura Automobili Torino; that's the company better known as MAT, makers of the New Stratos and contract engineering house for boutique screamers like the Aspark Owl electric hypercar, Apollo Intensa Emozione, and SCG003C. Garella told the outlet, "We have an agreement with General Motors" for a supply of Blackwings, which would be developed and built at the General Motors Propulsion Engineering Center (PEC) in Turin. Since 2005, the PEC has been used to develop GM's global diesel engines and electronics. MAT's plan is to put the V8 into a new limited-run car MAT is creating from its own design. Then another surprising turn: Belgium-based global auto supplier Punch Group bought the PEC, with plans to work with GM on projects in progress until at least the end of 2021. Nothing changes as far as MAT is concerned, except perhaps a chance for an even closer collaboration with Punch Turin.
